Headlamp Levelling

The 'Automatic Dynamic Headlamp Levelling System' consists of:

• An Automatic Dynamic Headlamp Levelling System ECU
• A level sensor for the front suspension
• A level sensor for the rear suspension
• A bi-polar stepper motor mounted in the housing of each headlamp

The Automatic Dynamic Headlamp Levelling System prevents the dipped beam dazzling oncoming road traffic by varying the angular position of the dipped (and main beam) headlamp units relative to the position of the vehicles suspension.

Static condition - Compensates for boot or occupant load condition.

Dynamic condition - Compensates for suspension movements due to acceleration and deceleration. The sensitivity of the system is dependent on vehicle speed and the rate of change of the vehicle speed.

High amplitude low frequency inputs such as those caused by potholes are filtered out to desensitise the system in constant speed situations.

Maintenance

Front Level Sensor

Removal

1. Disconnect the vehicle ride height sensor from the lower suspension arm.
2. Remove the ride height sensor from the subframe.

Installation

1. Install the vehicle ride height sensor (LH side). Torque to:
   • (M8 (subframe)) 22.5 Nm.

(M8 (lower arm)) 22.5 Nm.
