Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Windshield
Wipers, Blade Check” underScheduled Maintenance on
page 6-4for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeNormal Maintenance Replacement Parts on
page 6-16. Here’s how to remove the wiper blades:1. Turn on the wipers to the low wipe setting.
2. Turn off the ignition while the wipers are at the
outer positions of the wiper pattern. The blades
are more accessible for removal/replacement while
in this position.
3. Pull the windshield wiper arm away from the
windshield.
4. While holding the wiper arm away from the glass,
push the release clip from under the blade
connecting point and pull the old blade assembly
down toward the glass to remove it from the
wiper arm.
5. Push the new wiper blade securely on the wiper arm
until you hear the release clip “click” into place.

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 2-26.
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 key should come out only in LOCK.
With a manual transaxle, the key should come out
only in LOCK.
Contact your Saturn retailer if service is required.
