WARNING
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to
the child. ( P. 37)
■When installing a child restraint system
Follow the directions given in the child rest raint system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerving
or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
●Only put a forward-faci ng child restraint sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).

WARNING
■When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it could fall off the ch ild’s shoulder. Failing to do so may result in
death or serious injury in the event of sudden braking, sudden swerving or an acci-
dent.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufacturer.
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt will
not securely hold the child restraint system , which could cause death or serious injury
to the child or other passengers in the event of sudden braking, sudden swerving or an
accident.
■To correctly attach a child re straint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around the
anchors and that the seat belt is not caught behind the child restraint system. Make sure
the child restraint system is securely attached , or it may cause death or serious injury to
the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxi de (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open the
windows and have the vehicle inspected at your Lexus dealer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
engine.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the engine running in an area with snow build-up, or where it is snowing.
If snowbanks build up around the vehicle while the engine is running, exhaust gases
may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by your Lexus dealer.
