Automatic Transaxle 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 115.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to 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 Saturn retailer for service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try
to turn the ignition to LOCK in each shift lever
position.
With an automatic transaxle, the ignition
should turn to LOCK only when the shift lever
is in PARK (P). The ignition key should
come out only in LOCK.
With a manual transaxle, the ignition key
should come out only in LOCK.
Contact your Saturn retailer if service is required.
