Manual Headlamp Leveling - Halogen 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.

The manual system comprises the following components:

NOTE: Headlamp leveling is not available on NAS market vehicles with halogen headlamps.

two headlamp leveling motors
headlamp leveling rheostat rotary control.

A rotary thumbwheel controller is located adjacent to the Instrument Panel (IP) dimmer control in the auxiliary lighting switch. The rotary thumbwheel controller is connected to a rheostat which gives a variable output to the headlamp leveling stepper motors. The motors respond to the output and move to adjust the headlamp vertical alignment as required.

Movement of the leveling rotary control produces a variable voltage output (hardwired connection). The motors react to the supplied voltage and move the headlamp to the requested position which relates to the supplied voltage from the leveling rotary control. The headlamps can be lowered from their unladen position to compensate for changes in vehicle attitude due to loading.

The control has four defined positions to compensate for a drop in height at the rear of the vehicle and avoid dazzle to oncoming drivers. The positions are defined as follows:

ROTARY CONTROL ROTATION	VEHICLE LOAD
0	Driver only or Driver and front seat passenger
1	Driver and pass
2	Maximum gross vehicle weight
3	Maximum rear axle load
