Instead of trying to list everything here, we ask that you
contact your dealer in the area where you'll be parking
your vehicle. The dealer can give you the best advice for
that particular area.
Automatic Transaxle Operation
PARK (P): This position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.
2-20
Your automatic transaxle
has a shift lever located on
the console between the
seats.
{
CAUTION:
It is 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.
Do not leave your 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 your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See "Shifting Into Park (P)" in the
Index. If you are pulling a trailer, see "Towing
a Trailer" in the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle shift
lock control system. You have to apply your regular brake
before you can shift from PARK (P) when the ignition key
is in ON. If you cannot shift out of PARK (P), ease
pressure on the shift lever – push the shift lever all the
way into PARK (P) – as you maintain brake application.
