WARNING

Observe the following precautions.

Failure to do so may result in death or serious injury.

●

Do not adjust the position of the driver’s seat while driving.

Doing so could cause the driver to lose control of the vehicle.

●

Do not place a cushion between the driver or passenger and the seatback.

A cushion may prevent correct posture from being achieved, and reduce the effec-

tiveness of the seat belt and head restraint.

●

Do not place anything under the front seats.

Objects placed under the front seats may become jammed in the seat tracks and stop

the seat from locking in place. This may lead to an accident and the adjustment mech-

anism may also be damaged.

●

Always observe the legal speed limit when driving on public roads.

●

When driving over long distances, take regular breaks before you start to feel tired.

Also, if you feel tired or sleepy while driving, do not force yourself to continue driving

and take a break immediately.

The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a vehi-
cle rollover.

The pretensioners do not activate in the

event of a minor frontal impact, a minor

side impact or a rear impact.

■

Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if you

lean forward too quickly. A slow, easy motion will allow the belt to extend so that you can

move around fully.

■

Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even

slightly, the belt is locked in that position and cannot be extended. This feature is used to

hold the child restraint system (CRS) firmly. To free the belt again, fully retract the belt

and then pull the belt out once more. (

P. 57)

■

Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.

●

Use a child restraint system appropriate for the child, until the child becomes large

enough to properly wear the vehicle’s seat belt. (

P. 55)

●

When the child becomes large enough to properly wear the vehicle’s seat belt, follow

the instructions regarding seat belt usage. (

P. 32)

■

Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the first

collision, but will not activate for the second or subsequent collisions.

■

Seat belt extender

Seat belt pretensioners (front seats and outboard second-row seats)

If your seat belts cannot be fastened securely

because they are not long enough, a personal-

ized seat belt extender is available from your

Lexus dealer free of charge.

WARNING

Observe the following precautions to reduce the risk of injury in the event of sudden

braking, sudden swerving or an accident.

Failing to do so may cause death or serious injury.

■

Wearing a seat belt

●

Ensure that all passengers wear a seat belt.

●

Always wear a seat belt properly.

●

Each seat belt should be used by one person only. Do not use a seat belt for more

than one person at once, including children.

●

Lexus recommends that children be seated in the rear seat and always use a seat belt

and/or an appropriate child restraint system.

●

To achieve a proper seating position, do not recline the seat more than necessary. The

seat belt is most effective when the occupants are sitting up straight and well back in

the seats.

●

Do not wear the shoulder belt under your arm.

●

Always wear your seat belt low and snug across your hips.

■

Pregnant women

●

RX350L: Do not let third-row seat passen-

gers to use second-row seat seat belts.

Obtain medical advice and wear the seat belt

in the proper way. (

P. 32)

Women who are pregnant should position the

lap belt as low as possible over the hips in the

same manner as other occupants, extending

the shoulder belt completely over the shoulder

and avoiding belt contact with the rounding of

the abdominal area.
If the seat belt is not worn properly, not only the

pregnant woman, but also the fetus could suffer

death or serious injury as a result of sudden

braking or a collision.

WARNING

■

People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (

P. 32)

■

When children are in the vehicle
P. 66

■

Seat belt pretensioners

●

Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will

disperse the passenger’s weight, which prevents the sensor from detecting the pas-

senger’s weight properly. As a result, the seat belt pretensioner for the front passen-

ger’s seat may not activate in the event of a collision.

●

If the pretensioner has activated, the SRS warning light will come on. In that case, the

seat belt cannot be used again and must be replaced at your Lexus dealer.

■

Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoulder.

The belt should be kept away from your neck, but not falling off your shoulder. Failure to

do so could reduce the amount of protection in an accident and cause death or serious

injuries in the event of a sudden stop, sudden swerve or accident. (

P. 32)

■

Seat belt damage and wear

●

Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed in

the door.

●

Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts. Do

not use a damaged seat belt until it is replaced. Damaged seat belts cannot protect an

occupant from death or serious injury.

●

Ensure that the belt and plate are locked and the belt is not twisted.

If the seat belt does not function correctly, immediately contact your Lexus dealer.

●

Replace the seat assembly, including the belts, if your vehicle has been involved in a

serious accident, even if there’s no obvious damage.

●

Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.

Have any necessary repairs carried out by your Lexus dealer. Inappropriate handling

may lead to incorrect operation.

■

Using a seat belt extender

●

Do not wear the seat belt extender if you can fasten the seat belt without the extender.

●

Do not use the seat belt extender when installing a child restraint system because the

belt will not securely hold the child restraint system, increasing the risk of death or

serious injury in the event of an accident.

●

The personalized extender may not be safe on another vehicle, when used by another

person, or at a different seating position other than the one originally intended.

NOTICE

■

When releasing a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender, not

on the seat belt.

This helps prevent damage to the vehicle interior and the extender itself.

Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system components diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.

WARNING

■

SRS airbag precautions
Observe the following precautions regarding the SRS airbags.

Failure to do so may cause death or serious injury.

●

The driver and all passengers in the vehicle must wear their seat belts properly.

The SRS airbags are supplemental devices to be used with the seat belts.

●

The SRS driver airbag deploys with considerable force, and can cause death or seri-

ous injury especially if the driver is very close to the airbag. The National Highway

Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,

placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear

margin of safety. This distance is measured from the center of the steering wheel to

your breastbone. If you sit less than 10 in. (250 mm) away now, you can change your

driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com-

fortably.

• Slightly recline the back of the seat.

Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-

tance, even with the driver seat all the way forward, simply by reclining the back of

the seat somewhat. If reclining the back of your seat makes it hard to see the road,

raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle

has that feature.

• If your steering wheel is adjustable, tilt it downward. This points the airbag toward

your chest instead of your head and neck.

The seat should be adjusted as recommended by NHTSA above, while still maintain-

ing control of the foot pedals, steering wheel, and your view of the instrument panel

controls.

●

The SRS front passenger airbag also deploys with considerable force, and can cause

death or serious injury especially if the front passenger is very close to the airbag. The

front passenger seat should be as far from the airbag as possible with the seatback

adjusted, so the front passenger sits upright.

●

If the seat belt extender has been connected

to the front seat belt buckles but the seat belt

extender has not also been fastened to the

latch plate of the seat belt, the SRS front air-

bags will judge that the driver and front pas-

senger are wearing the seat belt even though

the seat belt has not been connected. In this

case, the SRS front airbags may not activate

correctly in a collision, resulting in death or

serious injury in the event of a collision. Be

sure to wear the seat belt with the seat belt

extender.

WARNING

■

SRS airbag precautions

●

Improperly seated and/or restrained infants and children can be killed or seriously

injured by a deploying airbag. An infant or child who is too small to use a seat belt

should be properly secured using a child restraint system. Lexus strongly recom-

mends that all infants and children be placed in the rear seats of the vehicle and prop-

erly restrained. The rear seats are safer for infants and children than the front

passenger seat. (

P. 55)

●

Do not sit on the edge of the seat or lean

against the dashboard.

●

Do not allow a child to stand in front of the

SRS front passenger airbag unit or sit on the

knees of a front passenger.

●

Do not allow the front seat occupants to hold

items on their knees.

●

Do not lean against the door, the roof side rail

or the front, side and rear pillars.

●

Do not allow anyone to kneel on the passen-

ger seats toward the door or put their head or

hands outside the vehicle.

WARNING

■

SRS airbag precautions

●

Do not hang coat hangers or other hard objects on the coat hooks. All of these items

could become projectiles and may cause death or serious injury, should the SRS cur-

tain shield airbags deploy.

●

If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to

remove it.

●

Do not use seat accessories which cover the parts where the SRS side airbags and

SRS seat cushion airbag inflate as they may interfere with inflation of the SRS airbags.

Such accessories may prevent the side airbags and SRS seat cushion airbag from

activating correctly, disable the system or cause the side airbags and SRS seat cush-

ion airbag to inflate accidentally, resulting in death or serious injury.

●

Do not strike or apply significant levels of force to the areas around the SRS airbag

components or the front doors.

Doing so can cause the SRS airbags to malfunction.

●

Do not touch any of the component parts immediately after the SRS airbags have

deployed (inflated) as they may be hot.

●

If breathing becomes difficult after the SRS airbags have deployed, open a door or

window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any resi-

due as soon as possible to prevent skin irritation.

●

If the areas where the SRS airbags are stored, such as the steering wheel pad and

front and rear pillar garnishes, are damaged or cracked, have them replaced by your

Lexus dealer.

●

Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will

disperse the passenger’s weight, which prevents the sensor from detecting the pas-

senger’s weight properly. As a result, the SRS front airbags for the front passenger

may not deploy in the event of a collision.

●

Do not attach anything to or lean anything

against areas such as the dashboard, steering

wheel pad and lower portion of the instru-

ment panel.

These items can become projectiles when the

SRS driver, front passenger and knee airbags

deploy.

●

Do not attach anything to areas such as a

door, windshield, side windows, front or rear

pillar, roof side rail and assist grip.

1-1. For safe use

RX350/RX350L_U

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the

extremely high speed deployment (inflation) by hot gases.

●

A loud noise and white powder will be emitted.

●

Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the

front seats, parts of the front and rear pillars, and roof side rails, may be hot for several

minutes. The airbag itself may also be hot.

●

The windshield may crack.

●

For Lexus Enform Safety Connect subscribers, if any of the following situations occur,

the system is designed to send an emergency call to the response center, notifying

them of the vehicle’s location (without needing to push the “SOS” button) and an agent

will attempt to speak with the occupants to ascertain the level of emergency and assis-

tance required. If the occupants are unable to communicate, the agent automatically

treats the call as an emergency and helps to dispatch the necessary emergency ser-

vices. (

P. 568)

• An SRS airbag is deployed.

• A seat belt pretensioner is activated.

• The vehicle is involved in a severe rear-end collision.

WARNING

■

Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without

consulting your Lexus dealer. The SRS airbags may malfunction or deploy (inflate)

accidentally, causing death or serious injury.

●

■

SRS airbag deployment conditions (SRS front airbags)

●

The SRS front airbags will deploy in the event of an impact that exceeds the set threshold

level (the level of force corresponding to an approximately 12-18 mph [20-30 km/h]

frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move

or deform on impact

• If the vehicle is involved in an underride collision, such as a collision in which the

front of the vehicle “underrides”, or goes under, the bed of a truck

●

Depending on the type of collision, it is possible that only the seat belt pretensioners will

activate.

●

The SRS front airbags for the front passenger will not activate if there is no passenger

sitting in the front passenger seat. However, the SRS front airbags for the front passen-

ger may deploy if luggage is put in the seat, even if the seat is unoccupied. (

P. 47)

●

The SRS seat cushion airbag on the front passenger seat will not operate if the occu-

pant is not wearing a seat belt.

■

SRS airbag deployment conditions (SRS side and curtain shield airbags)

●

The SRS side and curtain shield airbags will deploy in the event of an impact that

exceeds the set threshold level (the level of force corresponding to the impact force

produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle

cabin from a direction perpendicular to the vehicle orientation at an approximate

speed of 12 -18 mph [20 -30 km/h]).

●

Both SRS curtain shield airbags will deploy in the event of vehicle rollover.

●

All SRS side and curtain shield airbags will deploy in the event of a severe frontal colli-

sion.

■

Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS side and curtain shield airbags may also deploy if a seri-

ous impact occurs to the underside of your vehicle. Some examples are shown in the

illustration.

●

Hitting a curb, edge of pavement or hard sur-

face

●

Falling into or jumping over a deep hole

●

Landing hard or falling

1-1. For safe use

RX350/RX350L_U

The SRS curtain shield airbags may also deploy under the situations shown in the illustra-

tion.

■

Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear

collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a

collision of any type causes sufficient forward deceleration of the vehicle, deployment of

the SRS front airbags may occur.

■

Types of collisions that may not deploy the SRS airbags

(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to a

collision from the side at certain angles, or a collision to the side of the vehicle body other

than the passenger compartment.

●

The angle of vehicle tip-up is marginal.

●

The vehicle skids and hits a curb stone.

●

Collision from the side

●

Collision from the rear

●

Vehicle rollover

●

Collision from the side to the vehicle body

other than the passenger compartment

●

Collision from the side at an angle

1-1. For safe use

For safety

and security

RX350/RX350L_U

The SRS side airbags do not generally inflate if the vehicle is involved in a rear collision, if

it rolls over, or if it is involved in a low-speed side or low-speed frontal collision.

The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear

collision, if it pitches end over end, or if it is involved in a low-speed side or lowspeed fron-

tal collision.

■

When to contact your Lexus dealer
In the following cases, the vehicle will require inspection and/or repair. Contact your

Lexus dealer as soon as possible.

●

Any of the SRS airbags have been inflated.

●

Collision from the rear

●
