RX350_U_OM48E90UExhaust gas precautions Harmful substance to the human body is contained in exhaust gases if inhaled.WA R N I N G
Exhaust gases contain 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-deadness, 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 wh ile the engine is ru nning, 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.

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 child 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 restra int 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. ●
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, raise the seatback as much as
possible, move the seat to the rearmost posi-
tion, 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 restraint system, and the
head restraint can be removed, remove the
head restraint.
If the head restraint cannot be removed, raise
it to the uppermost position. ●
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 or rear 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 airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.

interferes with your child restraint
system. ( P. 1 6 7 )If the head restraint cannot be
removed, raise it to the uppermost
position.
Widen the gap between the seat cushion and seatback slightly.Child restraint system fixed with a child restraint LATCH anchor
