tofive different positions:

and windshield wipers when the engine is off. To
use ACCESSORY, push in the key and turn it toward
you. Your steering wheel will stay locked.
B (LOCK):This is the only position in which you can
insert or remove the key. This position locks the ignition,
steering wheel and transaxle. It’s a theft-deterrent
feature.Notice:If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the steering
wheel left and right while you turn the key hard.
Turn the key only with your hand. Using a tool
to force it could break the key or the ignition switch.
If none of these works, then your vehicle needs
service.

still turn the steering wheel. It doesn’t lock the
steering wheel. Use OFF if you must have your vehicle
pushed or towed.
D (RUN):This position is where the key returns to after
you start your vehicle. With the engine off, you can
use RUN to display some of your warning and indicator
lights.
E (START):This position starts your engine.
A warning chime will sound if you open the driver’s door
when the ignition is in OFF, LOCK or ACCESSORY
and the key is in the ignition.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. 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
Your automatic transaxle
will have a shift lever on
the console between
the seats.The graphic shown above is displayed on your
instrument panel cluster and will indicate the gear your
vehicle is in when you move.
Maximum engine speed is limited on automatic transaxle
vehicles when you’re in PARK (P) or NEUTRAL (N) to
protect driveline components from improper operation.
