Xenon Lighting System, Calibration

The headlamp levelling system must be calibrated after changing the headlamp, AHL control module or the front and rear load angle sensors. The system must also be calibrated after undoing or dismantling the front or rear load angle sensor.

Check the following points before carrying out calibration.

• The car must be level.
• The car must be unladen.
• Stabilize the suspension by rocking the car.
• The handbrake must not be applied.
• The xenon lamps must be turned on.

Connect the diagnostic tool and calibrate both headlamp/AHL control modules.

Check the function of the headlamps and clear any trouble codes.

Check the headlamp alignment and adjust if necessary. Refer to HEADLAMP ALIGNMENT  .
