Ignition Switch
The combined ignition switch/anti-theft lock is located on the right
side of the steering column and has four positions:
0-LOCK position: The key can be removed or inserted in this
position. To remove the key, push it in at position I, then turn it to
0 and pull it out. When the key is removed, the steering column
will lock.
NOTE:
On cars equipped with automatic transmissions, the transmission
must be in Park before pushing and turning the key to the 0-LOCK
position.
Never turn the ignition switch to the lock position or remove the
key while the car is in motion; the steering wheel can lock causing
a loss of directional control, and an accident could result.
I-ACCESSORY position: In this position, the accessory circuit is
on, but the ignition circuit is off.
if the key is difficult to turn from the 0 to the I position, turn the
steering wheel slightly to relieve pressure on the lock.
II-ON position: This is the normal running position.
III-START position: The starter will engage when the key is
turned to this position.
To remind you to remove the ignition key when leaving your car, a
beeper will sound if the key is still in the ignition when you open the
driver's door. The beeper system is deactivated when you turn the
ignition to 0 (Lock) and fully remove the key.
