WARNING
■Front passenger occupant classification system precautions
●Do not recline the front passeng er seatback so far that it touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that the
SRS airbags for th e front passenger will no t activate in the event of a severe accident.
If the seatback touches the rear seat, return the seatback to a position where it does
not touch the rear seat. Keep the front passenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the effec-
tiveness of the seat belt system.
●If an adult sits in the fron t passenger seat, the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit up
straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If
the “AIR BAG OFF” indicator still remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward.
●When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. ( P. 60)
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise, the
SRS warning light may come on to indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.
●Child restraint systems installed on the rear se at should not contact the front seat-
backs.
●Do not use a seat accessory, such as a cushion and seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.
●Do not place anything between the cons ole box and front passenger seat. Other-
wise, the system may not de tect the front passenger properly, leading to improper
operation of the airbags.
●Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.

WARNING
■When installing a child restraint system
Observe the following when installing child re straint system to the front passenger seat
if it is unavoidable. The front passenger SR S airbag inflates with considerable speed
and force that if not observed may lead to death or serious injury to the child.
●Never install a rear-facing child restraint sy stem on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the event of an accident, the force
of the rapid inflation of the front passenger airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is installed on the front passenger
seat.
●A forward-facing child restraint system ma y be installed on the front passenger seat
only when it is unavoidable. A child restraint system that requires a top tether strap
should not be used in the front passenger seat since there is no top tether strap
anchor for the front passenger seat.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front pillars or roof side rails from which the SRS side air-
bags or SRS curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the SRS side and curtain shield airbags inflate, and
the impact could cause death or serious injury to the child.
●When a booster seat is installed, always en sure 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 coul d fall off the child’s shoulder.
●A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restraint system on the front
passenger seat, adjust the seatback to the
most upright position, move the seat to the
rearmost position, and raise the seat to the
highest position, even if the “AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes with the instal-
lation of the child re straint system, and the
head restraint can be removed, remove the
head restraint.

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 on 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.
