3. With the latch open, pull the
wiper blade down towards the
windshield far enough to release
it from the J-hooked end of the
wiper arm.
4. Remove the wiper blade.
5. Reverse steps 1 through 3 for
wiper blade replacement.
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to a dealer for
service.
