Automatic Headlamp Leveling - Xenon Headlamps Only

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Automatic headlamp leveling is only available on vehicles with xenon headlamps. The system is not a dynamic headlamp leveling system and changes in vehicle inclination due to positive and negative acceleration are not compensated.

Automatic headlamp leveling provides for the static, periodic adjustment of the vertical aim of the headlamps to minimize glare to other road users when the vehicle attitude changes due to loading.

Automatic headlamp leveling is controlled by the BCM/GWM assembly.

The headlamp leveling system comprises the following components:

front and rear vehicle height sensors
two headlamp leveling, vertical adjustment motors
ignition in power mode 6 or above.

When the left steering column multifunction switch is moved to the side lamp or headlamp position, a Local Interconnect Network (LIN) bus message is passed from the Steering Wheel Module (SWM) to the BCM/GWM assembly for the selected function. The BCM/GWM assembly then issues a 'lights on' message on the High Speed (HS) Controller Area Network (CAN) powertrain systems bus.

Signals from the front and rear height sensors are used to periodically re-align the vertical aim of the headlamps to their optimum position.
