481-1. For safe use
Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
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 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 win-
dows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated 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 snow-
banks build up around the vehi-
cle 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 corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.
