Windscreen cleaner (Renault Laguna 2)

Automatic windshield wiper mode

Under normal operating conditions, the windshield wiper operates intermittently, at low or high speed. The wiper mode can be changed using the ring on the wiper stalk. The mode can also be changed automatically, depending on the vehicle speed (except for vehicles equipped with a rain sensor).

If the windshield wiper speed is selected while driving, then when the car stops, the windshield wiper switches to a lower speed:

• from continuous high speed operation to continuous low speed operation;
• from continuous low-speed operation to intermittent operation.

When the vehicle starts moving again, the wiper returns to the selected speed.

Note: If the vehicle is equipped with a rain sensor, the wiper speed does not depend on the vehicle speed.

Note: Any action on the windscreen wiper switch lever has priority and cancels the mode set by the UEC.

Automatic mode does not switch on if low or high windshield wiper speed is selected while the vehicle is stationary.

When the load on the wiper arms is too great (for example, at high speed, etc.) The UEC automatically switches the windscreen wiper to a lower speed.

In case of blocking of the windshield wiper mechanism (for example, when the brushes freeze to the windshield, etc.) The UEC automatically interrupts the power supply to the electric motor.

Rain sensor

On vehicles equipped with a rain sensor, the UEC does not control the intermittent wiper operation with a pause in operation. In this case, the wiper speed and the time delay between the movements of the brushes do not depend on the vehicle speed.

Please note: The windshield wiper differs on right-hand and left-hand drive vehicles.
