CAUTION
■Caution while driving
●Keep the trunk lid closed while driving.
If the trunk lid is left open, it may hit near-by objects while driving or luggage in
the trunk may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a serious
health hazard. Make sure to close the trunk lid before driving.
●Before driving the vehicle, make sure that the trunk lid is fully closed. If the trunk
lid is not fully closed, it may open unexpectedly while driving, causing an accident.
●Never let anyone sit in the trunk. In the event of sudden braking or a collision, they
are susceptible to death or serious injury.
■When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not allow children to enter the trunk.
If a child is accidentally locked in the trunk, they could overheat or suffocate.
●Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to operate unexpectedly, or cause the child’s
hands, head, or neck to be caught by the closing trunk lid.

Seat belt pretensioners (front seats)The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
Pre-collision seat belts (front seats of vehicles with pre-collision system)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt, thus enhancing the effectiveness
of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( →P. 212)
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudde n 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. 1 2 0 )

CAUTION
Observe the following precautions to reduce the risk of injury in the event of sudden
braking or an accident.
Failing to do so may cause death or severe 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.
●Do not recline the seat any more than necessary to achieve a proper seating
position. 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.
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading 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 detecting
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.

CAUTION
■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 tab 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 han-
dling of the pretensioner may prevent it from operating properly resulting in
death or serious injury.
■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 seatin g position other than the one originally
intended.
■When using the seat belt guide
Always make sure that the belt is not twisted, and runs freely through the guide.
■Before fastening the rear seat belt
Release the seat belt holder.
