WARNING
■Front passenger occupant classification system precautions
Observe the following precau tions regarding the front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON”
indicator light is illuminated. If you use the seat belt extender while the “AIR BAG
OFF” indicator light is illuminated, the SRS airbags for the front passenger will not
activate, which could cause death or seri ous injury in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback
pocket).
●Do not put weight on the front passenger seat by putting your hands or feet on the
front passenger seat seatback from the rear passenger seat.
●Do not let a rear passenger lift the front passenger seat with their feet or press on the
seatback with their legs.
●Do not put objects under the front passenger seat.

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 back door closed.
●If you smell exhaust gases in the vehicle even when the back door 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.

WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
●For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system which is correctly
installed. For installation details, refer to the operation manual enclosed with the child
restraint system. General inst allation instructions are provided in this manual.
●Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
weight and size of the child, installed on the rear seat. According to accident statistics,
the child is safer when proper ly restrained in the rear seat than in the front seat.
●Holding a child in your or someone else’s ar ms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between
the holder and the interior of the vehicle.
■Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerv-
ing, or an accident.
●If the vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has da mage that is not readily visible. In such cases, do not
reuse the restraint system.
●Make sure you have complied with all installa tion instructions provided with the child
restraint system manufacturer and th at the system is properly secured.
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the luggage compartment.

WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Never install a rear-facing ch ild restraint system 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.
●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, move the seat as far back as
possible, even if the “AIR BAG OFF” indicator
light is illuminated.
If the head restraint in terferes with the child
restraint system installation and the head
restraint can be remo ved, remove the head
restraint.
●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, side and rear pillars,
or roof side rails from which the SRS side air-
bags or SRS curtain shield airbags deploy
even if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.

WARNING
■When using a child restraint system
●Use a child restraint system suitable to the age and size of the child and install it to the
rear seat.
●Vehicles with third seats: Ch ild restraint system installed on the third seat should not
contact the second seatbacks.
●When installing a child restraint system on the second center seat, adjust both seat
cushions to the same position and align bo th seatbacks at the same angle. The seat-
backs must be adjusted to the same angle. Otherwise, the child restraint system can-
not be securely restrained an d this may cause death or serious injuries in the 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.
