1 Set speed adjustment switch 2 Time gap switch (only on vehicles with adaptive speed control fitted) 3 Cancel switch 4 Resume switch The speed control switches are located on the RH (right-hand)side of the steering wheel. The switches are connected via fly
leads to the clock spring. The speed control switches are resistive ladder type switches which vary the resistance of a 5 volt
signal sent to them. The signal is returned along a LIN bus to the instrument cluster. The instrument cluster routes the control signals to the ECM on the medium speed CAN
Speed control is engaged by rotating the speed adjustment switch to the + or - positions. Once engaged the speed can be
varied by the speed adjustment switches. Each press of the speed adjustment switch will increase or decrease the set speed
in steps of 1 mph (2 kph).
ADAPTIVE SPEED CONTROL MODULE
The adaptive speed control module, located on the drivers side at the bottom of the 'A' post. The control module is connected
to the other vehicle systems via the high speed CAN bus. Signals from the adaptive speed control forward looking radar sensor are received on a dedicated CAN bus between the two modules.
ADAPTIVE SPEED CONTROL RADAR SENSOR
The adaptive speed control radar sensor is located in the front bumper, on the RH side above the radiator grill behind the bumper cover. The sensor is connected to the adaptive speed control, module via a private CAN bus. If the unit is replaced in service the unit must be re-aligned vertically. Horizontal alignment is achieved by putting the sensor in service mode using an
approved Jaguar diagnostic system.

The lighting system has an 'auto' lights function which is controlled by the 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 LIN (local interconnect network) bus connection to the CJB . The auto lights can also be activated when the windshield wipers are activated by signals from the rain sensor, which is located at the top of the windshield or when the
driver activates the wipers in the fast wipe position.
Two levels of headlamp specification are available; halogen or xenon. In certain markets the headlamps feature a cornering
lamp or a static bending lamp which illuminates the area at the side of the vehicle when turning into driveways for 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.
The tail lamp comprises two separate lamp assemblies. 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 attached to the luggage
compartment lid. A side marker lamp is fitted to the rear fender tail lamp assembly and is fitted in all markets.
Two systems of headlamp leveling are available; manual leveling which is only available on halogen headlamps and static
dynamic 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 which periodically monitors the vehicle
attitude and adjusts the headlamp vertical alignment accordingly.

1 Headlamp leveling rotary thumbwheel (halogen headlamps only) 2 Instrument panel illumination dimmer thumbwheel 3 Luggage compartment lid release switch 4 Forward alert switch (if fitted) 5 Rear fog lamp switch The auxiliary lighting switch is located in the instrument panel, adjacent to the steering column. The switch has a rear fog
lamp switch and a rotary thumbwheel to adjust headlamp leveling on vehicles with halogen headlamps. The auxiliary lighting
switch also has a forward alert switch (if fitted) and a rotary thumbwheel for instrument panel illumination dimming.
The rear fog lamp switch is a non-latching switch which provides a momentary signal to the instrument cluster. The fog lamps
can only be activated if the ignition is in power mode 6 and the headlamp or auto headlamps are selected on. If the fog lamp
switch is pressed when the fog lamps are operating, they will be switched off. If the lighting control switch is moved to the
side lamp or off position or if the auto headlamps turns off the headlamps the rear fog lamps will be extinguished. If the
headlamps are subsequently turned on the rear fog lamp operation will not be active and the rear fog lamp switch must be
pressed to activate the lamps.
HEADLAMP ASSEMBLY
Two types of headlamp are available; xenon or halogen. The headlamp is secured in the front of the vehicle with three bolts;
one outboard bolt is screwed into the front upper cross member, one inboard bolt in the front upper body gusset and one bolt
located at the rear of the headlamp assembly which locates in the front fender reinforcing panel. Bulb replacement requires the
removal of the 3 bolts and the headlamp assembly.
The rear of the headlamp has removable panels which allow access to the bulbs for replacement. A large cover can be rotated
counter-clockwise for removal allows access the headlamp low beam halogen or xenon D1S bulb. Another large removable cover
can be rotated for removal to provide access to the high beam bulb, side lamp bulb and cornering/static bending lamp bulb (if
fitted).
The headlamps have 2 adjustment screws on the rear which allow for the manual setting of the vertical and horizontal
alignment.
On NAS vehicles, the headlamp is regarded as 'Visual Optically Left' aiming. The adjustment screws must be turned equal
amounts to maintain the correlation in the vertical axis only. There is no horizontal adjustment. Refer to the Service Repair
Procedures manual for headlamp alignment data and procedures.
Each headlamp has an integral 16 pin connector which provides inputs and outputs for the various functions of the headlamp
assembly. NOTE: RHD (right-hand drive) switch shown

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.
DAYTIME RUNNING LAMPS (DRL)
Refer to DRL section for details. Refer to: Daytime Running Lamps (DRL) (417-04 Daytime Running Lamps (DRL), Description and Operation).
REAR LAMP ASSEMBLY
The rear lamp assembly is a 2 piece unit, with one part located in the rear quarter panel and the second part attached to the
luggage compartment lid. The outer rear lamp assembly is located in a recess in the vehicle body. The lamp is secured with 2
studs inboard studs on the lamp body which are secured to the vehicle body with 2 nuts. A third outboard stud and nut secures
