Windshield Replacement
Keep in mind that your windshield is part of the Head-Up
Display (HUD) system. If you ever have to get your
windshield replaced, be sure to get one that is designed
for HUD or your HUD image may look blurred or out
of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
or cracking. SeeScheduled Maintenance on page 6-4.
It’s a good idea to clean or replace the wiper blade
assembly on a regular basis or when worn. For proper
windshield wiper blade length and type, seeNormal
Maintenance Replacement Parts on page 6-14.
To replace the wiper blade assembly, do the following:
1. Turn the ignition to OFF/ACC, with the engine off.
2. Turn on the windshield wipers and turn them off
again when the wipers are in the out-wipe
position. The driver’s side blade will be straight up
and down on the windshield.
3. Pull the windshield wiper assembly away from the
windshield.
