■When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In the event
that the rear seat cannot be used, the front seat can be used as long as the airbag
manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deploy-
ment (inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may
result in serious injury or even death.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if
inhaled.
CAUTION
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odor-
less. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an acci-
dent 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 any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional 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 any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.

• Ultrasonic waves emitted from devices such as the intrusion sensors of other
vehicles
• The movement of people outside the vehicle
●Unstable items, such as dangling accesso-
ries or clothes hanging on the coat hooks,
