10-32 Vehicle Care
To remove and replace the wiper
blade element do the following:
1. The wiper blade element has
two notches at one end which
are engaged by the bottom claw
set of the wiper blade. At the
notched end of the wiper blade,
pull the wiper blade element
from the wiper blade assembly.
2. To replace the element, start at
the heel end of the wiper blade,
which is the end nearest to
the base of the wiper arm, and
slide the wiper blade element,
notched end last, into the wiper
blade claw sets.
3. To engage the last claw into the
notched end of the wiper blade
element, squeeze the wiper
blade element at the notched
area, and push the wiper blade
element so the claw fits into the
notch.
4. Be sure the two wiper blade
element notches are engaged
by the last claw set, and that
all the other claws are properly
engaged in the slots of the wiper
blade element on both sides.

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 the dealer
for service.
