Guarding Against Exhaust Fumes - Ford 1996 Mustang Manual

For best results, plug the heater in at least three
hours before you start your vehicle. Using the
heater for longer than three hours will not
damage the engine, so you can plug it in at
night to start your vehicle the following
morning.
NOTE: Be sure to disconnect the engine block
heater before driving your vehicle.

Guarding Against Exhaust Fumes

Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
Do not start your vehicle in a closed
garage or other enclosed area. Never sit in
a stopped vehicle for more than a short
period of time with the engine running.
Exhaust fumes are toxic. See Guarding
Against Exhaust Fumes in this chapter for
more instructions.
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes.
Have the exhaust and body ventilation systems
checked whenever:
your vehicle is raised for service
the sound of the exhaust system changes
your vehicle has been damaged in a collision
Improve your ventilation by keeping all air inlet
vents clear of snow, leaves, and other debris.
