Adjustment

Before carrying out the adjustment, the vehicle must be moved and the light

module at the bottom of the right-hand A-pillar exposed. Disconnect white

2-pin socket housing (3) (Dummy, green wire) from branch A2, white 2-pin pin

housing of xenon headlight wiring harness A and connect white 2-pin socket

housing branch A3 (wire jumper, red wire) kept in the glovebox to branch A2,

white 2-pin pin housing of xenon headlight wiring harness A.The vehicle should

be parked unladen on a flat and even surface for the purpose of automatic

adjustment of the level sensor. Disengage gear or selector lever in position "N".

Release handbrake and start vehicle. Make sure that the battery voltage is not

below 13.0 V for the adjustment of the level sensor (battery must be charged).

Disconnect branch A3, white 2-pin socket housing (wire jumper, red wire) from

branch A2, white 2-pin pin housing of xenon headlight wiring harness A.

The adjustment is now completed. Reconnect white 2-pin socket housing (3) (Dummy, green wire) to free branch A2,

white 2-pin pin housing of xenon headlight wiring harness A.

Electrical adjustment is now functional.

Park vehicle and switch off ignition.

Place disconnected branch A3, white 2-pin socket housing (wire jumper, red wire) and the information leaflet

(Section 4) in the car’s glovebox as the adjustment procedure must be repeated in the event of any changes made to

the running gear or repairs carried out on the rear axle.

Reinstall the light module and adjust headlights with headlight adjuster (the headlights must be set mechanically to H-1%).

Encoding

This system does not require encoding.

Notes on checking cold light scan module

If the message "check low beam headlight or the symbol" appears in the

instrument cluster display, it is possible that fuse (1) in the cold light scan

module (2) is defective (500 mA slow-blow fuse). After replacing the fuse, there

still may be a fault in the cold light scan module or in the xenon headlight

(replace cold light scan module or xenon headlight).

Notes on checking the level sensor

The level sensor in the rear right wheelhouse is checked as follows:

- Expose light module (1) in right-hand A-pillar

- Park unladen vehicle on flat and even surface

- Disengage gear, release handbrake

- Connect voltmeter between branch A6, yellow/red wire of xenon headlight

wiring harness A and ground.

- Start vehicle

- Measure voltage (setpoint 1.0 V)

- Luggage compartment laden with 150 kg (2 persons)

- The voltage value must increase (approx. 1.2 to 2 Volt) after 20 seconds.

- If the voltage does not increase, either the control rod is detached (fixed) or

the control sensor is defective.
