Rear Wiper Blade Replacement
1. Lift the wiper blade assembly up
and out of the park rest position.

away from the backglass. The
backglass wiper blade will not
lock in a vertical position, so
care should be used when
pulling it away from the vehicle.
3. Turn the wiper blade assembly,
and pull it off of the wiper arm.
Hold the wiper arm in position
and push the blade away from
the wiper arm.
4. Replace the wiper blade.
5. Return the wiper blade assembly
to the park rest position.

Glass Replacement

If the windshield or front side glass
must be replaced, see your dealer
to determine the correct
replacement glass.
Vehicle Care

Headlamp Aiming

The vehicle has a visual optical
headlamp aiming system. The aim
of the headlamps has been preset
at the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the aim of the headlamps
may be affected and adjustment
may be necessary.
If oncoming vehicles flash their high
beams at you, this may mean the
vertical aim of the headlamps needs
to be adjusted.
It is recommended that the vehicle
be taken to the dealer for service if
the headlamps need to be adjusted.
It is possible, however, to re-aim the
headlamps as described.
