Running The Vehicle While Parked - Chevrolet 2009 TrailBlazer Owner's Manual

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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,
see Engine Exhaust on page 2-38.
CAUTION:
{
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly set.
CAUTION: (Continued)
CAUTION: (Continued)
Thevehicle can roll. Do not leave the vehicle when
the engine is running unless you have to. If you
have left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
CAUTION:
{
If the vehicle has four-wheel drive, it will be free to
roll — even if the shift lever is in P (Park) — if the
transfer case is in N (Neutral). So be sure the
transfer case is in a drive gear — not in N (Neutral).
See Four-Wheel Drive on page 2-30.
Follow the proper steps to be sure the vehicle will not
move. See Shifting Into Park on page 2-35.
If pulling a trailer, see Towing a Trailer on page 4-48.
