9-10 Driving and Operating
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use the Roadside
Assistance Program on page 13 6.
To get help and keep everyone in
the vehicle safe:
Turn on the hazard warning
flashers.
Tie a red cloth to an outside
mirror.
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.
Check again from time to
time to be sure snow does
not collect there.
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.

WARNING (Continued)
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 30.
Run the engine for short periods
only as needed to keep warm,
but be careful.
