dependant on a particular ignition mode status. The side lamps will also be illuminated when the lighting control switch is in
the AUTO position and a 'lights on' signal is received by the CJB from the rain/light sensor Side Marker Lamps (NAS only)

The side marker lamp is located in the outer part of the headlamp assembly. The side marker lamp uses a W5W wedge fitting
bulb. The bulb is fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an
aperture which connects with contacts in the headlamp housing. The side marker lamp is active at all times when the side
lamps are active.

AUTOMATIC HEADLAMP OPERATION

The automatic headlamp function is a driver assistance system. The driver can override the system operation by selection of
side lamp or headlamp on if the ambient light conditions require front and rear lighting to be active. The automatic headlamp
system uses a light sensor and the CJB, which are connected via a LIN (local interconnect network) bus to control the headlamp functionality. The light sensor is incorporated in the rain/light sensor located on the inside of the windshield, below
the rear view mirror. The wiper system also uses the rain/light sensor for automatic wiper operation.

The light sensor measures the ambient light around the vehicle in a vertical direction and also the angular light level from the
front of the vehicle. The rain/light sensor uses vehicle speed signals, wiper switch position and the park position of the front
wipers to control the system. The automatic headlamp operation uses ambient light levels which are monitored by photodiode
incorporated in the rain/light sensor. The rain/light sensor sends a lights on/off request to the CJB on the LIN bus, which responds by switching on the low beam headlamps, front side lamps and rear tail lamps. The automatic headlamps are
activated under the following conditions:

Twilight
Darkness
Rain
Snow
Tunnels
Underground or multistoried car parks.

Operation of the automatic headlamps requires the ignition to be in ignition mode 6, the lighting control switch to be in the
'AUTO' position and a lights on request signal from the light sensor. If the rain sensor signal activates the fast speed wipers,
the low beam headlamps are activated, providing the lighting control switch is in the 'AUTO' position.

HEADLAMP LEVELING

Headlamp leveling provides for the adjustment of the vertical aim of the headlamps. The leveling system is primarily required
to minimise glare to other road users when a heavy load is in the rear of the vehicle. Two systems of headlamp leveling are
available; manual and static dynamic.
Manual Headlamp Leveling

The manual system uses a thumbwheel rheostat to adjust the vertical alignment of the headlamps to compensate for differing
vehicle loading. The rotary thumbwheel is located on the auxiliary lighting switch, adjacent to the illumination dimmer
thumbwheel. Three positions are available to adjust the headlamps to a position to prevent glare to other road users.
Static Dynamic Headlamp Leveling
The static dynamic headlamp leveling system uses the following components:
Front and rear vehicle height sensors
Two headlamp leveling, vertical adjustment motors
Headlamp leveling module
Ignition in mode 6
Vehicle speed information from ABS module.
The static dynamic system uses height sensors fitted to the front and rear suspension and a headlamp leveling module which
periodically monitors the vehicle attitude and adjusts the headlamp vertical alignment accordingly.

Static dynamic headlamp leveling is controlled by a headlamp leveling module located in the lower instrument panel, behind
the glovebox.

The height sensors are both located on the RH side of the vehicle. The front sensor is attached to the front suspension lower arm with a strap and to the front sub frame with a bracket and 2 bolts. The rear sensor is attached to the rear suspension
upper control arm with a cable tied clip and to the rear sub frame with a bracket and 2 bolts. Each sensor has 3 connections to
the headlamp leveling module; power, ground and signal.

Safety Information

WARNINGS:


The Xenon Headlamp system generates up to 28,000 volts. Make sure that the headlamps are switched off before
working on the system. Failure to follow this instruction may lead to fatality.

The following safety precautions must be followed when working on the Xenon Headlamp system:
DO NOT attempt any procedures on the Xenon Headlamps or circuits when the system is energized.
Handling of the xenon bulb must be performed using suitable protective equipment, e.g. gloves and goggles. The glass
part of the bulb must not be touched.
Only operate the lamp in a mounted condition in the reflector.
All safety procedures and precautions must be followed to prevent personal injury.


CAUTION: Xenon bulbs must be disposed of as hazardous waste.

There are instructions on the correct procedures for Xenon Headlamp System repairs in the manual, refer to section 100-00 -
General Information, Standard Workshop Practices of the workshop manual.

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage.



3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to DTC Index.

Operation and Component Description
Description and Operation



CENTRAL JUNCTION BOX (CJB) System Operation

The CJB (central junction box) controls the operation of the DRL (daytime running lamps). The DRL are activated once the CJB detects an ignition on power mode 6 signal.
The CJB also monitors the lighting control switch and the auto lamps feature and overrides the DRL if required.


DAYTIME RUNNING LAMPS - CANADA Component Description

The DRL for this market use full intensity low beam headlamps. The side marker lamps, tail lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
PARK is not selected on the electronic transmission selector
Electronic Parking Brake (EPB) is off
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off or side lamps position.
NOTES:


If the lighting control switch is moved to the headlamp position, DRL are deactivated and normal side lamp and headlamp functionality is operational.


When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally.

The high beam headlamp function using the left hand steering column stalk switch will be deactivated. When the transmission
is in PARK, DRL are turned off. This is to reduce battery discharge during long periods of engine idling in cold climate conditions. When the electronic transmission selector is moved from the PARK position, normal DRL functionality is restored.
DAYTIME RUNNING LAMPS - DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND


NOTE: DRL for Poland is on vehicles from 2008MY.

DRL for these markets use full intensity low beam headlamps. Side lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off position.


NOTE: When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally. The high beam headlamp function using the left hand steering column stalk switch will be deactivated.

If the lighting control switch is moved to the side lamp or headlamp positions, DRL are deactivated and normal side lamp and headlamp functionality is operational.

AUTOMATIC HEADLAMPS

On vehicles fitted with the automatic headlamps feature, DRL are overridden if the lighting control switch is in the 'Auto' position and the CJB receives a signal from the rain/light sensor to activate the exterior lights.
When the CJB receives a signal to de-activate the automatic headlamps feature the DRL function is restored providing the parameters for DRL activation are met.
