10-28 Vehicle Care
To replace the windshield wiper
blade:
1. Pull the windshield wiper
assembly away from the
windshield.
2. Lift up on the latch in the middle
of the wiper blade where the
wiper arm attaches.
3. With the latch open, pull the
wiper blade down toward the
windshield far enough to release
it from the J-hooked end of the
wiper arm.
4. Remove the wiper blade.
Allowing the wiper blade arm to
touch the windshield when no
wiper blade is installed could
damage the windshield. Any
damage that occurs would not
be covered by the vehicle
warranty. Do not allow the wiper
blade to touch the windshield.
5. Reverse Steps 1 through 3 for
wiper blade replacement.
Headlamp Aiming
The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer
adjust the headlamps. To re-aim
the headlamps yourself, use the
following procedure.
The vehicle should be properly
prepared as follows:
. The vehicle should be placed so
the headlamps are 7.6 m (25 ft)
from a light‐colored wall.
. The vehicle must have all four
tires on a level surface which is
level all the way to the wall.
. The vehicle should be placed so
it is perpendicular to the wall or
other flat surface.
. The vehicle should not have any
snow, ice, or mud on it.
