For safety and security
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.
