WARNING

Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where
this may occur are listed below.

There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)

The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.

The sensor is covered in any way.

The vehicle is leaning considerably to one side.

On an extremely bumpy road, on an incline, on gravel, or on grass.

The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.

There is another vehicle equipped with parking assist sensors in the vicin-
ity.

The sensor is coated with a sheet of spray or heavy rain.

The sensor is drenched with water on a flooded road.

The vehicle is equipped with a fender pole or wireless antenna.

Towing eyelets are installed.

The bumper or sensor receives a strong impact.

The vehicle is approaching a tall or curved curb.

The detection range is reduced due to an object such as a sign.

In harsh sunlight or intense cold weather.

The area directly under the bumpers is not detected.

If obstacles draw too close to the sensor.

A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

A backlit license plate is installed.

In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

WARNING

Obstacles which may not be properly detected
The shape of the obstacle may prevent a sensor from detecting it. Pay par-
ticular attention to the following obstacles:

Wires, fences, ropes, etc.

Cotton, snow and other materials that absorb sound waves

Sharply-angled objects

Low obstacles

Tall obstacles with upper sections projecting outwards in the direction of
your vehicle

People may not be detected if they are wearing certain types of clothing.

Moving objects such as people or animals

NOTICE

When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.

The intuitive parking assist operation display flashes, and a buzzer sounds
when no obstacles are detected.

If the area around a sensor collides with something, or is subjected to
strong impact.

If the bumper collides with something.

If the display shows continuously without beeping, except when the buzzer
volume is muted.

If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.

Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

Drivin

Driving assist systems

ABS (Anti-lock Brake System)

Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface

Brake assist

Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation

VSC (Vehicle Stability Control)

Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces

TRAC (Traction Control)

Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads

Hill-start assist control

Helps to reduce the backward movement of the vehicle when start-
ing on an uphill

EPS (Electric Power Steering)

Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel

Active Torque Control 4WD (AWD models only)

Automatically  switches  from  front-wheel  drive  to AWD  (All-Wheel
Drive)  according  to  driving  conditions,  helping  to  ensure  reliable
handling and stability. Examples of conditions where the system will
switch  to  AWD  are  when  cornering,  going  uphill,  starting  off  or
accelerating, and when the road surface is slippery due to snow or
rain etc.

To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.

Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems

A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.

Any of the following conditions may occur when the above systems are
operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.

Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:

When the engine switch is turned to the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system)

If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.

326

SIENNA_OM_OM08025U_(U)

4-5. Using the driving support systems

Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.

Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:

The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline)

The vehicle is stopped

The accelerator pedal is not depressed

The parking brake is not engaged

Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:

The shift lever is shifted to P or N

The accelerator pedal is depressed

The parking brake is engaged

No more than 2 seconds have elapsed after the brake pedal is released

WARNING

The ABS does not operate effectively when

The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).

The vehicle hydroplanes while driving at high speed on wet or slick roads.

Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:

When driving on dirt, gravel or snow-covered roads

When driving with tire chains

When driving over bumps in the road

When driving over roads with potholes or uneven surfaces

WARNING

TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system is operating. Drive the
vehicle carefully in conditions where stability and power may be lost.

Hill-start assist control does not operate effectively when

Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.

Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.

When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.

Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern

and total load capacity. In addition, make sure that the tires are inflated

to the recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different

tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires

or wheels.

Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will

affect the driving assist systems, and may cause a system to malfunc-

tion.

Active Torque Control 4WD system (AWD models only)

The AWD system of this vehicle is intended to ensure driving stability on
normal roads. It is not designed for use in demanding situations such as
rally driving.

Take care when driving on slippery road surfaces.

Winter driving tips

Use fluids that are appropriate to the prevailing outside tempera-
tures.

• Engine oil
• Engine coolant
• Washer fluid

Have a service technician inspect the condition of the battery.

Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.

Ensure that all tires are the same size and brand, and that chains match
the size of the tires.

Perform the following according to the driving conditions:

Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.

To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.

Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.

Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.

Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

4-6. Driving tips

Drivin

Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.

Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.

If the vehicle is parked without setting the parking brake, confirm
that the shift lever cannot be moved out of P

: The shift lever will be locked if it is attempted to be shifted from P to any

other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.

Use the tire chains of correct size and type.

Use SAE Class “S” type radial tire chains, with the exception of radial
cable chains or V-bar type chains.

Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.

Tire chain installation
Observe the following precautions when installing and removing chains.

Install and remove tire chains in a safe location.

Install tire chains on the front tires only. Do not install tire chains on the rear
tires.

Install tire chains on front tires as tightly as possible. Retighten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).

Install tire chains following the instructions provided with the tire chains.

WARNING

Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.

Use tires of the specified size.

Maintain the recommended level of air pressure.

Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.

Use snow tires on all, not just some wheels.

Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.

Do not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.

Avoid driving on bumpy road surfaces or over potholes.

Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.

Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

NOTICE

Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.

Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
