WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
. Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe and/or the
fuel operated heater exhaust
system, if equipped. If the
vehicle has a diesel engine
and a fuel operated heater,
see “Fuel Operated Heater
(FOH)” in the diesel engine
supplement.
. Check again from time to
time to be sure snow does
not collect there.

WARNING (Continued)
. Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control Systems in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.

cannot see it or smell it, so you
might not know it is in the vehicle.
Clear away snow from around the
base of the vehicle, especially
any that is blocking the exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
