WARNING
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. This could lead to an acc ident, resulting in
death or serious injury.
■ When installing the driver’s floor mat
● Do not use floor mats designed for other models or different mo del 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.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle a nd may lead
to an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■ Important points while driving
● Double Cab and CrewMax models: Keep the back window closed.
● Double Cab and CrewMax models: If you smell exhaust gases in th e vehi-
cle even when the back window is closed, open the windows and h ave the
vehicle inspected at your Toyota dealer as soon as possible.
● Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to both driving and stopped or pa rked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.
■ 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 o pen 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.
