CAUTION
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, leading to an accident, or leading to death or a 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.

CAUTION
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.
●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.

cle is subjected to certain types of
severe frontal collision.
The seat belt pretensioners also activate
when the vehicle is subjected to certain
types of severe side collision.
The pretensioners do not activate in the
event of a minor frontal impact, a minor

■After the rear center seat belt has been used
■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.
■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. 5 8 )
●When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions regarding seat belt usage. (→P. 3 6 )
■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 regulations
If seat belt regulations exist in the country where you reside, please contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional for
seat belt replacement or installation. Stow the buckle as shown.

CAUTION
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.
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (→P. 3 6 )
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.

CAUTION
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (→P. 3 6 )
■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
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 any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
■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. 3 7 )
■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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●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 any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional. Inappropriate handling may lead
to incorrect operation.
