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.

{

WARNING

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 9‑20
.

WARNING

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. The vehicle 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).

Follow the proper steps to be sure
the vehicle will not move. See
Shifting Into Park on page 9‑18.

If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑43
