B (LOCK): This is the only position from which you
can remove the key. This position locks your ignition,
steering wheel and transaxle.
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.
C (OFF): This position unlocks the ignition, steering
wheel and transaxle but, does not send power to
any accessories. Use this position if your vehicle
must be pushed or towed, but never try
to
push-start
your vehicle.
D (RUN): This is the position to which the switch returns
after you start your engine and release the ignition key.
This is the position for driving. Even when the engine is
not running, you can use RUN to operate your electrical
accessories and to display some instrument panel
warning lights.
E (START): This position starts the engine. When the
engine starts, release the ignition key. The switch
will return to RUN for normal driving.
If the engine is not running, ACCESSORY and RUN
are positions that allow you to operate your electrical
accessories, such as the radio.
Retained Accessory Power (RAP)
With RAP, the power windows, power rear quarter
windows, audio system and the automatic level control
will continue to work up to 10 minutes after the
ignition key is turned to OFF and none of the doors
are opened.
