For safety and security
CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the
pedals while driving. An unexpectedly high speed may result or it may become diffi-
cult to stop the vehicle, leading to an accident, or leading to death or a serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year vehicles,
even if they are Lexus Genuine floor mats.
●Only use floor mats designed for the driver’s seat.
●Always install the floor mat securely using the retaining hooks (clips) provided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
●Check that the floor mat is securely fixed in
the correct place with all the provided
retaining hooks (clips). Be especially care-
ful to perform this check after cleaning the
floor.
●With the engine stopped
and the shift lever in P, fully depress each
pedal to the floor to make sure it does not
interfere with the floor mat.

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 your Lexus dealer as soon as pos-
sible.
■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.
