Windshield Wipe And Wash, Basic Function - GF82.30-P-9900A

Model All (CAR) 

Model All (4xWD) 

Overview 

This document contains the following information

General 

The windshield wiper and washer system consists of a parallel windshield wiper system with wiper motor, a windshield washer system pump, a washer fluid reservoir, the spray nozzle hoses and the spray nozzles.

The parallel windshield wiper system with reversing motor allows for wiping that gets very close to the A-pillar on the driver's side.

The wiping frequency can be adjusted to the degree of wetting of the windshield.

The pump of the windshield washer system supplies washer fluid to the windshield via several spray nozzles.

The windshield wipers wipe the water and partially dissolved dirt from the windshield.

In vehicles with a combustion engine, wiping and washing of the windshield is interrupted or not permitted when the engine is started.

Vehicles With Heated Windshield Washer System 

In order to guarantees trouble-free operation also at low temperatures, the following components are heated:

Function Requirements 

Function 

Wipe Windshield 

The wiping frequency and speed can be set using the combination switch on the steering column:

The single wipe function is activated by briefly pressing the combination switch up to the engagement point. The windshield is wiped once. The wiper speed corresponds to the speed of switch position 3.

If pressed for a longer period, wiping is carried out for max. 30 s. If a request is present for even longer, the system evaluates this as a switch defect and the actuation is canceled.

The windshield wiper system is switched off.

When switching from switch position 0 to switch position 1

or 2 the windshield is wiped once (reaction wipe).

The windshield wiper system is operated depending on the degree of wetting of the windshield.

A rain sensor behind the windshield records how wet it is.

The windshield washer system works with a low sensitivity.

The frequency of wiping is calculated based on how wet the windshield is.

The windshield wiper system is also operated depending on the degree of wetting of the windshield, but with greater sensitivity.

The frequency of wiping is calculated based on how wet the windshield is.

The windshield washer system runs continuously at a low speed.

The windshield wiper system is operated continuously at high speed.

IMPORTANT Automatic speed reduction:

At low speeds, less wetting of the windshield is assumed.

In the event of deceleration from more than 6 to under 3 km/h, the system reduces the specified wiping speed in switch position 3 or 4.

Wash Windshield 

Washing is activated by pressing the combination switch beyond the engagement point.

In addition to wiping, the system actuates the windshield washer system pump for max. 15 s.

During washing, wiping takes place at the wiper speed set on the combination switch.

At switch position 0, wiping is carried out as in switch position 3.

In switch position 0, another one to max. three wipes are carried out after the washing finishes.

Wiper Operation Suppression 

The wiper operation suppression prevents people from being splashed when climbing on or off due to a wiping process conducted on-on.

The wiper operation suppression is active when the following conditions are met:

When the front door is opened, the windshield wipers remain in the parking position despite a manual or automatic wipe request.

Any wiping procedure that has already started is terminated.

When the driver and driver's door are closed and one gear is selected or the clutch is engaged, wiper operation suppression is disabled.

Wipe And Wash Stop 

The wipe and wash stop prevents the moving wiper arms from causing damage to the vehicle when the hood is open.

If the hood is opened when the vehicle speed is below 3 km/h, the system immediately stops all activation.

If the hood is open, you can wipe again from a vehicle speed of 6 km/h.

Washing is possible again from a vehicle speed of 8 km/h.
