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 Service (U.S. and Canada) or Roadside Service (Mexico).
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.
- 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.
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.
If it takes some time for help to arrive, now and then when you run the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible to save fuel.
