Engine Exhaust
{ CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot
see or smell. It can cause unconsciousness
and death.
You might have exhaust coming in if:
• Your exhaust system sounds strange or
different.
• Your vehicle gets rusty underneath.
• Your vehicle was damaged in a collision.
• Your vehicle was damaged when driving
over high points on the road or over
road debris.
• Repairs were not done correctly.
• Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:
• Drive it only with all the windows down to
blow out any CO; and
• Have your vehicle fixed immediately.
Running Your Engine While You Are
Parked (Automatic Transmission)
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{ CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can happen
is a garage. Exhaust — with CO — can come
in easily. NEVER park in a garage with the
engine running.
Another closed-in place can be a blizzard.
See Winter Driving on page 4-38.
