Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay with the vehicle unless there is help nearby. If possible, use the Roadside Assistance Program. 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 (two inches) 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 System in the Index.
For more information about carbon monoxide, see
Engine Exhaust.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your 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.
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.
