Running Your Engine While You're Parked - GMC 1994 Sonoma Owner's Manual

Running Your Engine While You're Parked
(Automatic Transmission)
It's better not to park with the engine running. But if you ever have to, here
are some things to know.
I
A
CAUTION:
Idling the engine with the air system control off could allow
dmgerous exhaust into your vehicle (see the earlier Caution
under "Engine Exhaust").
Also, idling in a closed-in place can let deadly carbon monoxide
(CO) into your vehicle even if the fan switch 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 "Blizzard'9 in the
Index.)

A
CAUTION:
It can be dangerous to get out of your vehicle if the shift lever is
not fully in "P" (Park) with the parking brake firmly set. Your
vehicle can roll. Don't leave your vehicle when the engine is
running unless you have to. If you've left the engine running, the
vehicle can move suddenly. You or others could be injured. To be
sure
your
vehicle won't move, even when you're on fairly level
ground, always set your parking brake and move the shift lever
to "P" (Park).
If you have four-wheel drive with a manual transfer case shift lever and
your transfer case is in "N" (Neutral), your vehicle will be free to roll, even
if your shift lever is in " P ' (Park). So, be sure the transfer case is in a drive
gear
-
not in
"N"
(Neutral). Follow the proper steps to
be
sure your vehicle
won't move. See "Shifting Into 'P' (Park)" in the Index.
If you're pulling a trailer, see "Towing a Trailer" in the Index.
