5 Windshield washer: Pulling the lever from
its basic position towards the steering wheel
activates the windshield washer pump in the
first stage.
Releasing the lever causes the wiper to per-
form several dry wipes.
6 In the second stage, the windshield washer
and the wipers operate together. When the
ignition is switched on, the washer nozzles
are heated.
7 Headlight washer: Push lever toward instru-
ment cluster to operate headlight washer.
A separate pump supplies high-pressure
water to the spray nozzles located in front of
the headlights on the bumper. The high pres-
sure stream soaks the dirt on the lenses and
washes it off. Repeat the wash cycle as nec-
essary to remove heavy dirt accumulation.
The headlight washer system operates only with
the headlights on.
Avoid running the wiper blades over a dry
windshield to prevent scratching the glass.
Spray on washer fluid first. A scratched
windshield will reduce visibility.
Always loosen blades frozen to glass before
operating wipers to prevent damage to
wiper motor.
WARNING
Worn or dirty wiper blades will reduce visi-
bility, making driving hazardous. Clean blades
regularly to remove road film and carwash
wax buildup.
Clean all inside and outside window glass
regularly. See "Car care instructions".
Wiper interval
The wiper interval can be adjusted by turning the
thumbwheel in the instrument cluster.
