your foot on the regular brake, set
the parking brake.

held by the parking brake only.

regular brake.
Contact your dealer if service is

Wiper Blade Replacement
Windshield wiper blades should
be inspected for wear or cracking.
See Scheduled Maintenance on
page 11‑2 for more information
on wiper blade inspection.
Replacement blades come in
different types and are removed
in different ways. To remove the
wiper blade:
1. Pull the windshield wiper arm
connector away from the
windshield.
2. Squeeze the grooved areas on
each side of the blade, and turn
the blade assembly away from
the arm connector.
3. Install the new blade onto the
arm connector and make sure
the grooved areas are fully set
in the locked position.
For the proper type and size, see
Maintenance Replacement Parts on
page 11‑11.
Glass Replacement
If the windshield or front side
glass must be replaced, see your
dealer to determine the correct
replacement glass.
