Description
The car is equipped with a wash and wipe system to clean the windscreen and the headlamps. 5D: The car is equipped with a wash and wipe system to clean the tailgate window.
The system functions are controlled by a lever on the column integration module to the right of the steering wheel.
The washer and wiper system comprises:
Rain sensor
The rain sensor is placed on the inside of the windscreen forward of the inside rearview mirror. The rain sensor is a control module with built-in logic circuits. The control unit is activated by selecting the automatic mode with the wiper stalk-switch. The rain sensor senses the presence of rain or snow on the windscreen and transmits data relating to this to the rear electrical center (REC) which relays the information to the engine underhood electrical center (UEC) which in turn activates the windscreen wipers. A light sensor measures the outside light intensity so that the sensitivity of the rain sensor can be adjusted accordingly.
Windscreen wipers with rain sensor
The windscreen wiper assembly is located under the cover beneath the windscreen. It comprises a motor, arm assembly and two wiper arms with wiper blades. The wipers are controlled by the rain sensor and rear and underhood electrical centers.
The windscreen wipers have two speeds (high/low) and an automatic mode. There are three alternative levels of sensitivity for the rain sensor which can be selected by means of the steering wheel controls (633).
Windscreen wipers without rain sensor
The windscreen wiper assembly is located under the cover beneath the windscreen. It comprises a motor, arm assembly and two wiper arms with wiper blades. The wipers are controlled by the Underhood Electrical Center.
The windscreen wipers have two speeds (high/low) and one intermittent wiper position, the frequency of which can be regulated to intervals of between 2 and 15 seconds by a thumbwheel on the stalk-switch.
Headlamp washers
A washer jet is mounted on a telescopic cylinder in the bumper in front of each headlamp. The headlamp washers are activated at the same time as windscreen washing.
Washer assembly
The washer assembly is located at the front of the left-hand front wing. It consists of a reservoir with two pumps and a level switch. The washer nozzles are located on the bonnet.
Operation of the system is controlled by the underhood electrical center (UEC). A message is transmitted on the bus if the washer fluid level is low. The audio system generates a warning tone and a message is displayed on the SID.
Rear window wash and wipe, 5D
The rear window wiper unit is located in the tailgate spoiler and comprises a wiper motor and a washer nozzle. The system is operated using a slider on the wiper stalk switch. The following functions are available: single wiper stroke, intermittent wipe or wash and wipe.
The wiper arm is always parked in its starting position, even if the ignition is turned from ON while the wiper arm is in motion. The logic for this function is in REC.
