3-2. Opening, closing and locking the doors

NOTICE

Back door damper stays

The  back  door  is  equipped  with  damper  stays  that  hold  the  back  door  in
place.
Observe the following precautions. 
Failure to do so may cause damage to the back door damper stay, resulting
in malfunction.

Do not place your hand on the damper stay or apply lateral forces to it.

To prevent back door closer malfunction

Do not apply excessive force to the back door while the back door closer is
operating.

To prevent damage to the power back door

Make  sure  that  there  is  no  ice  between  the  back  door  and  frame  that
would prevent movement of the back door. Operating the power back door
when excessive load is present on the back door may cause a malfunc-
tion.

Do not apply excessive force to the back door while the power back door
is operating.

Take care not to damage the sensors (installed on the right and left edges
of the power back door) with a knife or other sharp object. If the sensor is
disconnected, the power back door will not operate in automatic operation.

Do not attach any foreign objects, such
as stickers, plastic sheets, or adhesives
to the damper stay rod.

Do not touch the damper stay rod with
gloves or other fabric items.

Do  not  attach  any  accessories  other
than  genuine  Toyota  parts  to  the  back
door.

Battery-saving function

In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.

When the entry function has not been used for 5 days or more

When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more

If the entry function has not been used for 14 days or more, the vehicle can-
not be unlocked by a door other than the driver’s door. To unlock the vehicle,
grip  the  driver’s  door  handle  or  use  the  wireless  remote  control  or  the
mechanical key.

The system will resume operation when...

The vehicle is locked using the lock sensor when carrying the electronic key
on your person.

The vehicle is locked/unlocked using the wireless remote control. (

P. 111)

P. 503)

Conditions affecting operation

P. 119

Notes for the entry function

Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle, near

the ground, or in a high place when the doors are locked or unlocked.

• The  electronic  key  is  on the  instrument  panel,  floor or  in  the glove  box

when the engine is started or engine switch modes are changed.

Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.

As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.

The  doors may unlock or lock  if a  large  amount  of water  splashes on  the
door handle, such as in the rain or in a car wash when the electronic key is
within  the  effective  range.  (The  doors  will  automatically  be  locked  after
approximately 60 seconds if the doors are not opened and closed.)

If the wireless remote control is used to lock the doors when the electronic
key  is  near  the  vehicle,  there  is  a  possibility  that  the  door  may  not  be
unlocked  by  the  smart  key  system.  (Use  the  wireless  remote  control  to
unlock the doors.)

If power slide door is unable to operate due to prohibition by the power slid-
ing door main switch, the door unlock and open operation will not be per-
formed. (

3-2. Opening, closing and locking the doors

Note for locking the doors

Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.

When the lock operation is performed using the lock sensor, recognition sig-
nals  will  be  shown  up  to  two  consecutive  times. After  this,  no  recognition
signals will be given.

If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)

If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

The  lock  sensor  may  not  work  properly  if  it  comes  into  contact  with  ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.

Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

Notes for the unlocking function

Gripping the front door handle when wearing a glove may not unlock or lock
the door.

A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to
the original position and check that the doors have unlocked before pulling
the door handle.

If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped or
one of sliding door handles is pulled.

When the vehicle is not driven for extended periods

To  prevent  theft  of  the  vehicle,  do  not  leave  the  electronic  key  within  6 ft.
(2 m) of the vehicle.

The smart key system can be deactivated in advance. (

the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention may not operate.)

If the smart key system does not operate properly

Locking and unlocking the doors: Use the mechanical key. (

When  the  occupant’s  lower  back
presses  against  the  seatback
during  a  rear-end  collision,  the
head  restraint  moves  slightly  for-
ward  and  upward  to  help  reduce
the  risk  of  whiplash  on  the  seat
occupant.

WARNING

When adjusting the seat position

Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.

Do not put your hands under the seat or near the moving parts to avoid
injury. 
Fingers or hands may become jammed in the seat mechanism.

Make sure to leave enough space around the feet so they do not get stuck.

Seat adjustment

Be careful that the seat does not hit passengers or luggage.

To  reduce  the risk  of sliding  under  the lap  belt during a  collision,  do  not
recline the seat more than necessary. 
If the seat is reclined too far, the lap belt may slide past the hips and apply
restraint  forces  directly  to  the  abdomen  or  your  neck  may  contact  the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

Manual seat: After adjusting the seat, make sure that the seat is locked in
position.

WARNING

When folding the rear seatbacks down

Observe the following precautions. Failure to do so may result in death or
serious injury.

Do not fold the seatbacks down while driving.

Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P.

Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.

Do not allow children to enter the luggage compartment.

Be careful not to get any part of your body pinched by a seat.

Seat adjustment

Be careful that the seat does not hit passengers or luggage.

To  reduce  the risk  of sliding  under  the lap  belt during a  collision,  do  not
recline the seat more than necessary. 
If the seat is reclined too far, the lap belt may slide past the hips and apply
restraint  forces  directly  to  the  abdomen,  or  your  neck  may  contact  the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident. 
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

After returning the rear seatbacks or installing seats

Observe the following precautions. Failure to do so may result in death or
serious injury.

Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.

Check that the seat belts are not twisted or caught in the seatback.

Make sure the seat is locked in place by trying to shake the seatback and
lift up the seat cushion.

Removing the second seats

Do not leave a seat in the vehicle if it has been disengaged from the floor.

Do not sit on or place anything on a seat that has been removed from the

WARNING

Stowing the third seats

Make sure that the seat path is clear before moving the seat. Otherwise,
injury  may  result  from  contact  with,  or  by  being  pinched  by  parts  of  the
seat.

Manual  third  seats:  Do  not  sit  on  the  third  seat  when  it  is  in  the  stowed
position with the seatback upright.

Power third seats: Do not continue the stowing operation when the indica-
tor above the stowing switch and returning switch comes on or flashes. An
object or a person may be caught in the seat.

Power  third  seats:  During  the  stowing  operation,  to  prevent  the  vehicle
from moving, do not shift the shift lever out of P with the engine switch in
the “ON” position (vehicles without a smart key system) or IGNITION ON
mode (vehicles with a smart key system).

When  adjusting  the  seat  position or  the  ottoman  (vehicles  with  Otto-
man seats)

Make  sure  to  leave  enough  space  around  the  feet  so  as  not  to  get  them
caught.

When using the ottoman (vehicles with Ottoman seats)

Do not sit on the ottoman. Seat belts may not be properly worn which may
result in death or serious injury.

Stow the ottoman when you get in and out of the vehicle or when the otto-
man is not in use to avoid stumbling over it.

Do not use the ottoman feature when the vehicle is in motion. The ottoman
feature should only be used when the vehicle is stationary. If the ottoman
feature is in use during an accident the lap belt may slide past the hips.
This could also result in restraint forces being applied to the abdomen or
your  neck  may  contact  the  shoulder  belt,  increasing  the  risk  of  death  or

When starting off on a uphill

The hill-start assist control is available. (

P. 322)

Driving in the rain

Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.

Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.

Refrain  from  high  speeds  when  driving  on  an  expressway  in  the  rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.

Engine speed while driving

In the following conditions, the engine speed may become high while driving. 
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.

The vehicle is judged to be driving uphill or downhill

When the accelerator pedal is released

Restraining the engine output (Brake Override System)

When the accelerator and brake pedals are depressed at the same time, the
engine output may be restrained.

A warning message is displayed on the multi-information display while the
system is operating. (

P. 474, 481)

Breaking in your new Toyota

To extend the life of the vehicle, observing the following precautions is recom-
mended:

For the first 200 miles (300 km):
Avoid sudden stops.

For the first 500 miles (800 km):
Do not tow a trailer.

For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.

Drum-in-disc type parking brake system

Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-
form the bedding down operation.

Operating your vehicle in a foreign country

Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

When starting the vehicle

Always  keep  your  foot  on  the  brake  pedal  while  stopped  with  the  engine
running. This prevents the vehicle from creeping.

When driving the vehicle

Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal. 
• Accidentally  depressing  the  accelerator  pedal  instead  of  the  brake

pedal will result in sudden acceleration that may lead to an accident.

• When backing up, you may twist your body around, leading to a diffi-

culty in operating the pedals. Make sure to operate the pedals properly.

• Make  sure  to  keep  a  correct  driving  posture  even  when  moving  the

vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.

• Depress  the  brake  pedal  using  your  right  foot.  Depressing  the  brake

pedal using your left foot may delay response in an emergency, result-
ing in an accident.

Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

When driving the vehicle

During  normal  driving,  do  not  turn  off  the  engine. Turning  the  engine  off
while  driving  will  not  cause  loss  of  steering  or  braking  control,  but  the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so. 
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: 

P. 463

Use  engine  braking  (downshift)  to  maintain  a  safe  speed  when  driving
down a steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (

P. 233)

Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving. 
Doing so may result in a loss of vehicle control.

Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Proceed with all
due caution if it becomes unavoidable to drive off-road.

AWD models: Do not drive across a river or through other bodies of water.
This  may  cause  electric/electronic  components  to  short  circuit,  damage
the engine or cause other serious damage to the vehicle.

Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to  determine whether the  tires on your  vehicle are high-speed capability
tires or not before driving at such speeds.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

198

SIENNA_OM_OM08035U_(U)

4-1. Before driving

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

When driving on slippery road surfaces

Sudden  braking,  acceleration  and  steering  may  cause  tire  slippage  and
reduce your ability to control the vehicle.

Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.

After  driving  through  a  puddle,  lightly  depress  the  brake  pedal  to  make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

When shifting the shift lever

Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R. Doing so may cause the
engine to stall or lead to poor brake and steering performance, resulting in
an accident or damage to the vehicle.

Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.

Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.

Do not shift the shift lever to a driving position while the vehicle is moving
backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.

Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.

Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear other than P or N may lead to unexpected
rapid acceleration of the vehicle that may cause an accident and result in
death or serious injury. Doing so can damage the transmission and may
result in a loss of vehicle control.

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)

Have the brake pads checked and replaced by your Toyota dealer as soon
as possible. 
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.

When the vehicle is stopped

Do not race the engine. 
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.

In order to prevent accidents due to the vehicle rolling away, always keep
depressing  the  brake  pedal  while  the  engine  is  running,  and  apply  the
parking brake as necessary.

If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.

Avoid revving or racing the engine. 
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

When the vehicle is parked

Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun. 
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a

fire.

• The  temperature  inside  the  vehicle  may  cause  the  plastic  lenses  and

plastic material of glasses to deform or crack.

• Soft  drink  cans  may  fracture,  causing  the  contents  to  spray  over  the

interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.

cle.

Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.

Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.

If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.

Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off. 
Doing so may cause burns.

When taking a nap in the vehicle

Always  turn  the  engine  off.  Otherwise,  if  you  accidentally  move  the  shift
lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

When braking

When the brakes are wet, drive more cautiously. 
Braking distance increases when the brakes are wet, and this may cause
one  side  of  the  vehicle  to  brake  differently  than  the  other  side. Also  the
parking brake may not securely hold the vehicle.

If the brake booster device does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In  this  case,  braking  is  still  possible,  but  the  brake  pedal  should  be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.

Do not pump the brake pedal if the engine stalls. 
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.

The brake system consists of 2 individual hydraulic systems: If one of the
systems  fails,  the  other  will  still  operate.  In  this  case,  the  brake  pedal
should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.

If the vehicle becomes stuck (AWD models)

Do not spin the wheels excessively when any of the tires is up in the air, or
the  vehicle  is  stuck  in  sand  or  mud,  etc.  This  may  damage  the  driveline
components or unexpectedly propel the vehicle forward or backward, caus-
ing an accident.

NOTICE

When driving the vehicle

Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the engine output.

Do  not  use  the  accelerator  pedal  or  depress  the  accelerator  and  brake
pedals at the same time to hold the vehicle on a hill.

When parking the vehicle

Always set the parking brake, and shift the shift lever to P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

Avoiding damage to vehicle parts

Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time. 
Doing so may damage the power steering motor.

When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.

If you get a flat tire while driving

A flat or damaged tire may cause the following situations.

It may be difficult to control your vehicle.

The vehicle will make abnormal sounds or vibrations.

The vehicle will lean abnormally.

Hold  the  steering  wheel  firmly  and  gradually  depress  the  brake  pedal  to
slow down the vehicle.
Information on what to do in case of a flat tire. (

P. 485, 499)

When encountering flooded roads

Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:

Engine stalling

Short in electrical components

Engine damage caused by water immersion

In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:

Brake function

Changes in quantity and quality of oil and fluid used for the engine, tran-
saxle, transfer (AWD models), rear differential (AWD models), etc.

Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.

Cargo and luggage

Cargo capacity depends on the total weight of the occupants. 
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)

Steps for Determining Correct Load Limit 

(1) Locate  the  statement  “The  combined  weight  of  occupants  and

cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard. 

(2) Determine the combined weight of the driver and passengers that

will be riding in your vehicle. 

(3) Subtract  the  combined  weight  of  the  driver  and  passengers  from

XXX kg or XXX lbs.

(4) The resulting figure equals the available amount of cargo and lug-

gage load capacity. 
For example, if the “XXX” amount equals 1400 lbs. and there will be
five  150  lb  passengers  in  your  vehicle,  the  amount  of  available
cargo and luggage load capacity is 650 lbs. (1400 - 750 (5



150) =

650 lbs.)

(5) Determine the combined weight of luggage and cargo being loaded

on  the  vehicle.  That  weight  may  not  safely  exceed  the  available
cargo and luggage load capacity calculated in Step 4. 

(6) If your vehicle will be towing a trailer, load from your trailer will be

transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. (

P. 516)

Take  notice of the following information about storage  precau-
tions, cargo capacity and load:

Cargo capacity
Total  load  capacity  (vehicle
capacity weight) (

P. 516)

When  2  people  with  the  combined  weight  of A  lb.  (kg)  are  riding  in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load capacity
will be C lb. (kg) as follows: 
B

*

2

 lb. (kg) - A

*

1

 lb. (kg) = C

*

3

 lb. (kg)

*

1

: A = Weight of people

*

2

: B = Total load capacity

*

3

: C = Available cargo and luggage load

In  this  condition,  if  3  more  passengers  with  the  combined  weight  of

D lb. (kg) get on, the available cargo and luggage load will be reduced

E lb. (kg) as follows: 

C lb. (kg) - D

*

4

 lb. (kg) = E

*

5

 lb. (kg)

*

4

: D = Additional weight of people

*

5

: E = Available cargo and luggage load

As  shown  in  the  example  above,  if  the  number  of  occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due to the additional occupants. In
other  words,  if  an  increase  in  the  number  of  occupants  causes  an
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.
