Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-25.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to ON/RUN,
but do not start the engine. Without applying the
regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), contact your dealer/retailer
for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK/OFF in each shift lever position.
With an automatic transmission, the ignition should
turn to LOCK/OFF only when the shift lever is in
PARK (P). The ignition key should come out only in
LOCK/OFF.
With a manual transmission, the ignition key should
come out only in LOCK/OFF.
Turn the steering wheel to the left and to the right. It
should only lock when turned to the right. Contact your
dealer/retailer if service is required.
