Driving
Refueling
Clear snow from underneath and
around your vehicle, particularly the
tail pipe, before starting the engine:
Running the engine when a vehicle is
stopped in deep snow is dangerous.
The exhaust pipe could be blocked by
the snow, allowing exhaust gas to
enter the cabin. Because exhaust gas
contains poisonous carbon monoxide,
it could cause loss of consciousness or
even death to occupants in the cabin.
