Porsche 928 ST1991 Owner's Manual page 48

5 Windshield washer: Pulling the lever
from its basic position towards the steer-
ing wheel activates the windshield
washer pump in the first stage.
Releasing the lever causes the wiper to
perform 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 in-
strument 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
pressure stream soaks the dirt on the
lenses and washes it off. Repeat the wash
cycle as necessary 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 be-
fore 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.
Intensive windshield cleaning
With the intensive cleaning feature you can re-
move even firmly adhering silicon dirt from the
windshield. Briefly depress the switch and the
metering pump will pump the Special Porsche
Silicon Remover onto the windshield.
The length off spraying is limited by a time-delay
relay in order to prevent excessive use. If neces-
g sary, repeat the operation. Then turn on the
windshield washer system.
