cooling duct.
The windshield washer is operated by pressing the button at the end of the wiper control stalk switch. Pressing and
releasing the button operates the washer for 1 to 1.4 seconds and the wiper completes three sweeps. An optional drip wipe
function adds a further sweep of the wiper after a 4 second delay, to clear residual fluid from the windshield. If the button is
held depressed, the washer and wiper will operate continuous ly for up to 20 seconds. When the button is released, the
wiper will again complete three further sweeps.
Headlamp Powerwash

The headlamp powerwash system incorporates a chromed twin nozzle assembly mounted on the chromed bumper blade
immediately in front of each pair of he adlamps. Each nozzle assembly is connected via snap fittings to a powerwash pump
mounted adjacent to the windshield wash pump on the rear face of the washer fluid reservoir.The powerwash system
operates in conjunction with the windshield washers when the ignition switch is in position II and the headlamp switch is in
the dip or main beam position. When powerwash is initially activated, a wash cycle commences, consisting of two 400 ms
pulses separated by a three second delay. If powerwash is still selected on completion of this cycle, it will continue to
operate at the same frequency for a maximum period of 20 se conds. To conserve washer fluid, headlamp powerwash will
only function on every sixth operation of the windshie ld wash switch.When the 'WASHER FLUID LOW' message is
illuminated, the windshield washer will continue to operat e for a limited period but the headlamp powerwash will not
function until the fluid level is restored.
Rain Sensing System
The rain sensing system installed form so me markets, provides automatic wiper operation when rain is detected on the
windshield. The system detects differing le vels of rainfall and varies wiper operation ranging from intermittent to maximum
continuous, to suit prevailing requirements.
The system which is brought into operation by selecting AUTO on the wiper control switch bezel, does not preclude normal
manual control of wiper operation.
The system consists of a rain sensor, an electronic control module and a dedicated wiper control switch.
The rain sensor is an optical transducer that is sensitive to changes in infra-red light penetration of the windshield created
by the refractive effects of water drople ts. The sensor elements consist of two groups of light emitting diodes which
alternately project infra-red light onto th e windshield and a photo-diode that receiv es resulting reflections from the glass. A ll
of the infra-red light is reflected back from a moisture-free windshield, resulting in a contact 5V output signal from the
sensor and no wiper activation. Rain falling on the light sensing area of the wi ndshield results in refraction and diffusion of a
proportion of the projected light with a corresponding imbalance of light received by the photodiode. This results in pulsed
outputs from the sensor, the frequency and duration of which are directly proportional to the number and size of water
droplets respectively. These pulses together with wiper switch position signals are received by the sensor control module
and processed to mimic column switch gear operation. In this recognisable form, signals are input to the body processor
module (BPM) where they are interprete d as normal wiper operation requests.

The rain sensor unit is installed on the inside of the windshield within the rear view mirror stem cover. The unit is secured t o
the glass by a special adhesive th at facilitates service removal. When installing a rain sensor unit, it must be positioned in
the clear circle within the obscuration band.

The rain sensor control module is a non- serviceable unit installed in the engine bay cool box and connected to the rain
sensor unit and the body processor module.
