2021 TOYOTA TUNDRA warning

781-1. For safe use
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.
