Engine Exhaust; Running The Vehicle While Parked - Buick Automobile User Manual

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:
•
The 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 the exhaust system has
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 the Vehicle While Parked

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 2-37.
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 4-17.
