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 difficult 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 Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● 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 careful 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 inter-
fere with the floor mat.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhale.
CAUTION
Exhaust gases include harmful carbon monoxide (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 Toyota
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 Toyota dealer.

■ If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not

not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by your Toyota dealer immedi-
ately if this occurs.
