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.

CAUTION:

Idling the engine with the climate control
system off could allow dangerous 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 is at the highest setting. One place this
can happen is a garage. Exhaust

with

can come in easily. NEVER park in a

garage with the engine running.

Another closed

in place can be a blizzard.

See “Blizzard” in the Index.

CAUTION:

It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) 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 PARK (P).

Four

wheel drive vehicles with the transfer case

in NEUTRAL will allow the vehicle to roll, even if
your shift lever is in PARK (P). So, be sure the
transfer case is in a drive gear

not in

NEUTRAL. Always set your parking brake.

Follow the proper steps to be sure your vehicle won’t
move. See “Shifting Into PARK (P)” in the Index.

If you’re pulling a trailer, see “Towing a Trailer” in
the Index.
