WARNING

Observe the following precautions.

Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the ped-

als while driving. An unexpectedly high speed may result or it may become difficult to

stop the vehicle. This could lead to an accident, resulting in death or serious injury.

■

When installing the driver’s floor mat

●

Do not use floor mats designed for other models or different model year vehicles,

even if they are Lexus Genuine floor mats.

●

Only use floor mats designed for the driver’s seat.

●

Always install the floor mat securely using the retaining hooks (clips) provided.

●

Do not use two or more floor mats on top of each other.

●

Do not place the floor mat bottom-side up or upside-down.

■

Before driving

●

Check that the floor mat is securely fixed in

the correct place with all the provided retain-

ing hooks (clips). Be especially careful to per-

form this check after cleaning the floor.

●

With the engine stopped and the shift lever in

P, fully depress each pedal to the floor to

make sure it does not interfere with the floor

mat.

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.

1-1. For safe use

Seat belts

●

Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.

●

Position the lap belt as low as possi-
ble over the hips.

●

Adjust the position of the seatback.
Sit up straight and well back in the
seat.

●

Do not twist the seat belt.

To fasten the seat belt, push the plate
into the buckle until a click sound is
heard.
To release the seat belt, press the
release button.

Push the seat belt shoulder anchor
down while pressing the release but-
ton.
Push the seat belt shoulder anchor
up.

Move the height adjuster up and down

as needed until you hear a click.

Make sure that all occupants are wearing their seat belts before driving the
vehicle.

For safety

and security

For children or smaller-than-average
people, slide the seat belt comfort
guide forward so that the shoulder belt
does not sit close to the person’s neck.

The pretensioner helps the seat belt to
quickly restrain the occupant by
retracting the seat belt when the vehi-
cle is subjected to certain types of
severe frontal collision.

The front seat pretensioners also acti-

vate when the vehicle is subjected to

certain types of severe side collision.

The pretensioner does not activate in the event of a minor frontal impact, a minor side

impact, a rear impact or a vehicle rollover.

■

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. (

■

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. 59)

●

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

the instructions regarding seat belt usage. (



P. 36)

■

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

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.

Failure 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.

WARNING

■

Pregnant women

■

People suffering illness

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



P. 36)

■

When children are in the vehicle

Do not allow children to play with the seat belt. If the seat belt becomes twisted around

a child’s neck, it may lead to choking or other serious injuries that could result in death.

If this occurs and the buckle cannot be unfastened, scissors should be used to cut the

belt.

■

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 detect-

ing the passenger’s weight properly. As a result, the seat belt pretensioner for the

front passenger’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. 36)

Obtain medical advice and wear the seat belt

in the proper way. (



P. 36)

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

■

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 is 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 using 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.

■

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.

WARNING

■

SRS airbag precautions

●

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.

●

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. 59)

●

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.

●

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.
