■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-

may lead to death or a serious health
hazard.
●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.
