WIPERS AND WASHERS

DESCRIPTION AND OPERATION

Description

General
The wipers and washers system is controlled by the Body Control Unit (BCU) on receipt of requests made by the driver 
or the rain sensor unit (if fitted). All wiper functions for the front and rear wipers are controlled from a multifunction 
wash/wipe switch assembly located on the right hand side of the steering column.

The wiper and washer system comprises:

l

Front and rear wiper motors

l

A front wiper linkage

l

Two front and one rear wiper arms and blades

l

Two front washer jets and one rear washer jet (incorporated with rear wiper arm)

l

A washer reservoir and three pumps

l

A wash/wipe control column switch.

Other items are added to enhance the wiper system:

l

Heated front washer jets

l

Headlamp wash/wipe system

l

A rain sensor for automatic wiper control.

The wiper system can be optionally equipped with a rain sensor. The sensor, located below the interior rear view 
mirror, detects rain drops on the windscreen and automatically operates the wipers in the intermittent mode. The 
column stalk switch must be in the intermittent position for rain sensor controlled wiper operation.

The front wiper system has four wiper stages of operation and four intermittent wiper delay periods. The four wiper 
stages are as follows:

l

Flick wipe

l

Intermittent

l

Normal (slow) speed continuous

l

Fast speed continuous.

The intermittent, normal and fast speeds are affected by road speed. The intermittent wiper delay periods change with 
the road speed, with the delay decreasing as the road speed increases. The normal continuous operation changes to 
intermittent operation when the vehicle is stationary. The fast speed operation changes to normal operation when the 
vehicle is stationary.

The wiper and washers operate with the ignition switch in positions I or II (aux or ign). Wiper functions are suspended 
during engine cranking to reduce battery power consumption under high load conditions.
