Running Your Engine While You're
Parked (Automatic Transaxle)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
/r\
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 switch is at the highest setting. One place
this can happen is a garage. Exhaust
--
with
CO
--
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.)
A
CAUTION:
t 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).
Follow the proper steps to be sure your vehicle won't
move. See "Shifting Into PARK (P)" in
the
Index.
If you are parking on
a hill
and if you're pulling a
trailer, also see "Towing a Trailer'' in the Index.
