the wiper arm connector and pull
the wiper blade away from the
arm connector.

assembly, hold the wiper arm in
position, and push the blade
away from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade
assembly to the rest position on
the glass.

Head‐Up display (HUD) system
and the windshield needs to be
replaced, get one that is designed
for HUD or the HUD image may
look out of focus.
