LOCK
(B):
Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only
position in which you can remove the key. This locks
your steering wheel, ignition and transaxle (on
automatic models).
OFF (C): This position unlocks the steering wheel and
ignition, but does not send electrical power to any
accessories. Use this position if your vehicle must be
pushed or towed, but never try to push-start your
vehicle. A warning chime will sound if you open the
driver's door when the ignition is off and the key is in
the ignition.
RUN
@): This position is where the key returns after
you start your engine and release the switch. The switch
stays in the RUN position when the engine is running.
But even when the engine is not running, you can use
RUN to operate your electrical power accessories, and
to display some instrument panel warning lights.
START
(E): This
position starts your engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.
Note that even if the engine is not running, the positions
ACCESSORY and RUN are on positions that allow you
to operate your electrical accessories, such as the radio.
On manual transaxle vehicles, turning the key to
LOCK will lock the steering column and result in
a loss of ability to steer the vehicle. This could
cause a collision. If you need to turn the engine
off while the vehicle is moving, turn the key only
to OFF. Don't press the key release button while
the vehicle is moving.
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. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
