Care of the Head-Up Display
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry it.
Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If You Can’t See the HUD Image When the Ignition
Is On
D Is anything covering the HUD unit?
D Is the HUD dimmer setting bright enough?
D Is the HUD image adjusted to the proper height?
D Still no HUD image? Check the fuse in the
instrument panel fuse block. See “Fuses and Circuit
Breakers” in the Index.
If the HUD Image Is Not Clear
D Is the HUD image too bright?
D Are the windshield and HUD lens clean?
The windshield is part of the HUD system. If you ever
need a new windshield, be sure to get one designed for
HUD. If you don’t, the HUD image may look blurred
and out of focus.
