Exterior Lighting: Overview

Exterior Lighting

OVERVIEW
Three levels of exterior lighting are available depending on vehicle specification:
- Halogen and manual headlamp leveling
- Xenon with LED (light emitting diode) signature lighting and automatic headlamp leveling
- Adaptive Xenon HID with LED (light emitting diode) signature lighting, automatic headlamp leveling and static bending lamps
- Automatic - Linked with automatic windscreen wipers
- Automatic High Beam Assist
A light switch module is located in the LH (left-hand) steering column multifunction switch and allows the driver to select the appropriate operation of the exterior lighting systems.
The rear lamp assemblies contain side lamps, stop lamps, reverse lamps and turn signal indicators. Rear fog lamps are mounted in the rear bumper. The rear lamp assemblies require removal for bulb replacement.
All versions of the headlamps have impact resistant polycarbonate lenses. Removable covers at the rear of the headlamps allow for bulb replacement. The headlamps require removal for bulb replacement.
The headlamps use a projector unit. Bi-function HID headlamps and the AFS headlamps use a D3S xenon bulb which operates in both low and high beam. Halogen projector headlamps use a HB3 halogen bulb which also operates in both low and high beam.
Headlamp leveling is automatic on the HID headlamps. Front and rear height sensors are located on the LH (left-hand) side of the front and rear axles. These measure the vehicle altitude and a headlamp leveling module, which is located on the bulkhead 'A' pillar behind the glovebox, automatically controls the headlamp vertical alignment. Manual headlamp leveling is used only on ROW vehicles fitted with halogen projector lamps, a rotary leveling thumbwheel is located on the dash near the door.
Headlamp powerwash is a standard fitment on HID headlamps.
Turn signal indicators and high and low beam functions are controlled from the LH (left-hand) steering column multifunction switch. The turn signal indicators have a lane change feature. A single press and release of the multifunction switch in either direction will operate the selected turn signal indicators for 3 cycles.
The exterior lighting is controlled by the CJB (central junction box). The CJB (central junction box) is the main controlling module for vehicle body systems and is located behind the glovebox in the instrument panel.
The CJB (central junction box) provides circuit protection for all exterior lighting circuits.
