OVERVIEW
The lighting systems are cont rolled by the Engine junction box (E JB), Rear junction box (RJB) and
the Central junction box (CJB). The two boxes contain fuses, relays and microprocessors to
control the power supply and functionality of the lighting systems.
Driver lighting sele ctions using the Left-hand (LH) steering column multifunction switch or the
auxiliary lighting switch are pass ed to the Central junction box (C JB) via the instrument cluster.
The lighting system has an 'auto' lights function which is controlled by the Central junction box
(CJB) on receipt of signals from the rain/light sensor located at the top of the windscreen. The
exterior lights are turned on or off in response to ambient light signals from the rain/light sensor
on a Local interconnect network (LIN) bus connectio n to the Central junction box (CJB). The auto
lights can also be activated wh en the windshield wipers are acti vated by signals from the rain
sensor, which is located at the t op of the windshield or when the dr iver activates the wipers in the
fast wipe position.
Two levels of headlamp specification are availa ble; halogen or xenon. In certain markets the
headlamps feature a cornering lamp or a static bend ing lamp which illuminates the area at the side
of the vehicle when turning into driveways fo r example. North American Specification (NAS)
vehicles have a side marker lamp installed in the headlamp assembly. Replacement of any of the
headlamp bulbs requires removal of the headlamp assembly.
Two systems of headlamp leveling ar e available; manual leveling which is only available on
halogen headlamps and static dy namic leveling which is available on xenon headlamps. The
manual system uses a thumbwheel rheostat to adjust the vertical alignment of the headlamps to
compensate for differing vehicle loading. The static dynamic system uses height sensors fitted to
the front and rear suspension and a headlamp leveling module wh ich periodically monitors the
vehicle attitude and adjusts the headlamp vertical alignment accordingly.
The headlamps are fitted with a tourist lever which allows the vehicle to be driven in opposite drive
hand markets without applying blanking decals to the headlamp lens. A lever, accessible from the
rear inside of the headlamp, moves a flap to blan k off a portion of the beam spread and prevent
glare to oncoming drivers. The headlamp assembly requires removal to access the tourist lever.
The tail lamp comprises two separate lamp asse mblies. The turn signal indicator, side and stop
lamps and reverse lamps are located in each rear fender tail lamp assembly. The rear fog lamps
are located in separate units atta ched to the luggage compartment lid. A side marker lamp is fitted
to the rear fender tail lamp assembly and is fitted in all markets.
The turn signal indicator and re verse lamps use Phillips Hypervisi on glass filament bulbs. The rear
fog lamps, side lamps, stop lamps and the Hi gh Mounted Stop Lamp (HMSL) use Light emitting
diode (LED)'s.
