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 2-31.
{ 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. 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 it is on
fairly level ground, always set
the parking brake and move the
automatic transmission shift lever
to P (Park), or the manual
transmission shift lever to Neutral.
Follow the proper steps to be
sure the vehicle will not move.
See Shifting Into Park (Automatic
Transmission) on page 2-29
and Parking the Vehicle (Manual
Transmission) on page 2-31.
If pulling a trailer, see Towing a
Trailer on page 4-42.
