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 2-35.
{
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
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 (Automatic Transmission)
on page 2-32.
If parking on a hill and pulling a trailer, see Towing a
Trailer (Automatic Transmission) on page 4-35 or
Towing a Trailer (Manual Transmission) on page 4-41.
