The bi-xenon headlamp uses a projector lens, similar to the halogen headlamp. The projector module comprises an ellipsoidal
lens and a reflector. The projector reflector collects the light produced by the halogen bulb and projects the light into a focal
plane containing a shield. The contour of the shield is projected onto the road by the lens. A complex surface reflector is used
for the halogen fill in high beam lamp. This type of reflector is divided into separate parabolic segments, with each segment
having a different focal length. The low and high beam bulbs are quartz halogen H7, with a rating of 55W. The bulbs are
retained in the headlamp unit with conventional wire retaining clips.
A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves a flap to blank off
a portion of the beam spread to enable the vehicle to be driven in opposite drive hand markets without applying blanking
decals to the headlamp lens. The beam is changed by removing the access cover at the rear of the lamp assembly and moving
a small lever located near the bulb holder, at the side of the projector.
NOTE: The tourist lever is not fitted to NAS vehicles.
WARNING: The Xenon system generates up to 30000 volts and contact with this voltage could lead to fatality. Make sure
that the headlamps are switched off before working on the system.
The following safety precautions must be adhered to when working on the xenon low beam headlamp system:
DO NOT attempt any procedures on the xenon headlamps when the lights are switched on.
Handling of the D1S xenon bulb must be performed using suitable protective equipment; for example gloves and
goggles. The glass part of the bulb must not be touched.
Xenon bulbs must be disposed of as hazardous waste.
Only operate the bulb in a mounted condition in the projector module installed in the headlamp.
The xenon headlamp is known as 'bi-xenon' because it operates as both a low and high beam headlamp unit. The xenon lamp,
or High Intensity Discharge (HID) lamp as they are sometimes referred to, comprises an ellipsoidal lens with a solenoid
controlled shutter to change the beam output from low to high beam.
NOTE: If the lighting control switch is in the 'off' position, both the xenon lamp and the halogen high beam lamp will
operate when the high beam 'flash' function is operated.
The xenon headlamp system is controlled by the CJB using a control module for each headlamp and an igniter. The control modules and the igniters provide the regulated power supply required to illuminate the bulbs through their start-up phases of
operation.
The xenon headlamp is a self contained unit located within the headlamp assembly. The unit comprises a reflector, an adaptor
ring, the lens, a shutter controller and the xenon bulb, which together forms an assembly known as the projector module. The
reflector is curved and provides the mounting point for the xenon bulb. The bulb locates in a keyway to ensure the correct
alignment in the reflector and is secured by a plastic mounting ring. The bulb is an integral component of the igniter and is
electrically connected by a connector located in the igniter unit.
The shutter controller is a solenoid which operates the shutter mechanism via a lever. The shutter is used to change the beam
projection from low beam to high beam and vice versa.
The xenon bulbs illuminate when an arc of electrical current is established between 2 electrodes within the bulb. The xenon
gas sealed in the bulb reacts to the electrical excitation and the heat generated by the current flow to produce the
characteristic blue/white light.
To operate at full efficiency, the xenon bulb goes through 3 full stages of operation before full output for continuous operation
is achieved. The 3 phases are; start-up phase, warm-up phase and continuous phase.
In the start-up phase, the bulb requires an initial high voltage starting pulse of up to 30000 volts to establish the arc. This is
produced by the igniter. The warm-up phase begins once the arc is established. The xenon control module regulates the supply
to the bulb to 2.6A which gives a lamp output of 75W. During this phase, the xenon gas begins to illuminate brightly and the
environment within the bulb stabilizes, ensuring a continual current flow between the electrodes. When the warm-up phase is
complete, the xenon control module changes to continuous phase. The supply voltage to the bulb is reduced and the operating
power required for continual operation is reduced to 35W. The process from start-up to continuous phase is completed in a very
short time.
The xenon control modules (one per headlamp) receive an operating voltage from the CJB when the headlamps are switched on. The modules regulate the power supply required through the phases of start-up.
The igniters (one per headlamp) generate the initial high voltage required to establish the arc. The igniters have integral coils
which generate high voltage pulses required for start-up. Once the xenon bulbs are operating, the igniters provide a closed
circuit for the regulated power supply from the control modules.

Halogen Low/high Beam Headlamp
The halogen low/high beam headlamp uses a projector lens, similar to the xenon headlamp. The projector module comprises
an ellipsoidal lens and a reflector. The projector reflector collects the light produced by the halogen bulb and projects the light
into a focal plane containing a shield. The contour of the shield is projected onto the road by the lens. The low/high beam
bulbs are quartz halogen and are retained in the headlamp unit with conventional wire retaining clips.
A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves a flap to blank off
a portion of the beam spread to enable the vehicle to be driven in opposite drive hand markets without applying blanking
decals to the headlamp lens. The beam is changed by removing the access cover at the rear of the lamp assembly and moving
a small lever located near the bulb holder, at the side of the projector.
Halogen High Beam Headlamp - Xenon and Halogen
The xenon and halogen headlamps use a complex surface reflector for the halogen fill in high beam lamp only lighting unit,
which is of the same design on both headlamp types. This type of reflector has the reflector divided into separate parabolic
segments, with each segment having a different focal length.
The high beam headlamp bulbs are quartz halogen and are retained in the headlamp unit with conventional wire retaining
clips.
Cornering Lamps
NOTE: The cornering lamps are not fitted to NAS vehicles.
The cornering lamps are an optional feature designed to illuminate the direction of travel when cornering at low speeds. The
design of the lens projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The cornering
lamp is incorporated into the headlamp assembly and shares the same housing as the low beam headlamp. The cornering lamp
uses a 35W Halogen H8 bulb which is permanently located in an integral holder which is connected on the headlamp housing.
The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover
on the base of the headlamp housing.
The cornering lamps are controlled by the LH steering column multifunction switch with the lighting control switch in the headlamp position and the ignition in power mode 6. The cornering lamps are supplied power via the ignition circuit to ensure
that they do not function with the headlamp delay feature. The cornering lamps are deactivated if the vehicle speed exceeds
25 mph (40 km/h). Only one cornering lamp will illuminate at any one time. If the left hand turn signal indicators are selected
on, the left hand cornering lamp will be illuminated and vice versa, providing the vehicle speed and lighting control switch
positions are correct.
Static Bending Lamps
NOTE: The static bending lamps are not fitted to NAS vehicles.
The static bending lamps are designed to illuminate the direction of travel when cornering at low speeds. The static bending
lamp functionality, which is controlled by the CJB and the headlamp leveling module, operates using inputs from the steering angle sensor and vehicle speed information from the ABS (anti-lock brake system) module. The static bending lamp is
incorporated into the headlamp assembly and shares the same housing as the low beam headlamp. The design of the lens
projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The static bending lamp uses a
35W Halogen H8 bulb which locates in a holder which is connected via wires to the main connector on the headlamp housing.
The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover
at the rear of the headlamp housing.
The static bending lamps operate with a steering angle sensor CAN bus signal which is received by the CJB. The CJB monitors this signal and vehicle speed and activates the static bending lamp bulb. When the operation parameters of the lamp are
reached, the CJB fades the static bending lamp bulb on using a PWM (pulse width modulation) voltage over a period of approximately 2 seconds. When the lamp is switched off, the CJB fades the bulb off by decreasing the PWM voltage in a linear manner depending on steering angle and vehicle speed. The cornering lamps can only be active for a maximum of 3 minutes.
NOTE: Static bending lamps only operate when the transmission is in DRIVE or in SPORT.
Turn Signal Indicators
The turn signal indicator lamp is incorporated into the outer part of the headlamp assembly. The turn signal indicator lamp
uses a PY21W bayonet orange colored bulb in ROW markets, a S8W 27/7W wedge bulb is used in NAS markets. The bulb is
fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an aperture in the
headlamp housing and rotated to lock into position.
When active, the turn signal indicator lamps will flash at a frequency cycle of 380ms on and 380ms off. If a bulb fails, the
remaining turn signal lamps bulbs continue to flash at normal speed. The turn signal indicators in the instrument cluster will
flash at double speed to indicate the bulb failure to the driver.
Side Lamps
The side lamp is located between the headlamp projector module and the high bean headlamp. The side lamp uses a W5W
wedge fitting bulb which locates in a holder which connected via wires to the main connector on the headlamp housing. The
holder is a push fit into a receptacle in the headlamp housing. The bulb is accessible by removal of the inner cover on the rear
of the headlamp housing. Access to the bulb requires removal of the headlamp from the vehicle. The side lamps are operated
by selecting side lamps or headlamps on the lighting control switch. The side lamps are functional at all times and are
Page 2034 of 3039
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

The turn signal indicator, side and stop lamps and reverse lamps are located in each outer rear lamp assembly. The side lamps
and stop lamps use 24 LED's. The 24 LED's are illuminated at a higher intensity than the side lamp when the stop lamp switch is operated by pressing the brake pedal. A side marker lamp is fitted to the outer rear lamp assembly and is fitted in all
markets. The side marker lamp also uses 4 LED's and are active at all times when the side lamps are selected on.
The stop lamps can also be activated by the adaptive speed control system. A signal from the adaptive speed control module
is sent via the high speed CAN bus to the RJB which activates the stop lamps until an off message is received. Turn Signal Indicator
The turn signal indicator lamp uses a Phillips Hypervision glass filament bulb. The bulb is located in a holder which has
contacts which mate with contacts on lamp body. The holder locates in the lamp body and is rotated to lock.
If a bulb fails, the remaining turn signal indicator lamps continue to flash at the normal speed. The applicable turn signal
indicator in the instrument cluster will flash at double speed to indicate the bulb failure to the driver. www.JagDocs.com

The console can be removed by carefully levering out
the rear edge of the housing to release 2 spring clips, and then pulling the console rearwards to release 2 locating tabs.
Removal of the console is required to replace any of the interior or map reading lamp bulbs.
The interior lamps and air bag off warning lamp in the front overhead console are common to all vehicles. The overhead
console can also contain security system intrusion detection module and volumetric sensors, sunroof switch and a voice
activation microphone depending on vehicle specification and market.
The interior lamp can operated manually using the JaguarSense feature to switch the lamp on and off. The lamp is also
controlled as part of the automatic interior lighting system.
The map reading lamps only operate manually using the JaguarSense feature to activate the lamps.
The interior and map reading lamp bulbs are located in holders which locate in a PCB. The PCB also provides for the operation
of the ambience lighting LED's, the air bag off warning lamp and the JaguarSense proximity sensors which are integral with the PCB.
The overhead console also contains 2 LED's for the ambience lighting system. The ambience lighting is part of the lighting control switch functionality and is subject to the setting of the instrument panel illumination dimmer control in the auxiliary
lighting switch. The ambience lighting provides very limited illumination of the instrument panel and floor console when the
vehicle is being driven without affecting the driver's visibility. www.JagDocs.com

Anti-Theft - Active System Operation
The active anti-theft system is available with three different levels of vehicle protection depending on market specification:
Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.
The system is controlled by software in the CJB and RJB and indicates a trigger condition: Visually, using the direction indicators, and
Audibly, using the vehicle horn and either a passive or active sounder to indicate a trigger condition.
The passive sounder takes the form of an anti-theft disc horn located at the rear of the engine compartment on the LH side. The active sounder takes the form of a battery backed sounder located in the same position.
Depending on market specification, the battery backed sounder may be fitted with an inclination sensor. Both types of battery
backed sounder are visually identical and can only be identified by their part number. Both are also intelligent units, and
communicate to the CJB over a LIN (local interconnect network) bus connection.
Monitoring of the hinged panels is carried out using switches located in each door latch assembly, the engine-compartment-lid
latch assembly, and the luggage-compartment-lid latch assembly. The condition of the switches is monitored by the CJB.
Monitoring of front door lock status is carried out using switches located in the door latch mechanisms. The condition of the
switches is monitored by the front door modules and transmitted to the CJB over the medium speed CAN (controller area
network) bus.
Monitoring of the cabin interior is carried out using an intrusion detection module mounted behind the roof console. The
intrusion detection module comprises an ultrasonic sound wave sensor to determine if there is movement within the cabin.
Information from the intrusion detection module is communicated to the CJB over a LIN bus connection.
CAUTIONS:
The intrusion detection module electrical connections, particularly those to the sensors mounted in the roof console, are
very delicate and must be handled with care.
The intrusion detection module is an electro-statically sensitive part and should only be handled in an electro-statically
controlled environment.
When armed, the active anti-theft system can be triggered in one of the following ways:
A door ajar switch indicates a door has been opened.
The engine compartment lid or luggage compartment lid ajar switches indicate that either has been opened.
Either front door latch mechanism indicates a door has been unlocked.
The emergency key blade is used to open either the LH front door or luggage compartment.
The CJB or RJB are disconnected (this may result in only a partial trigger).
An attempt is made to start the engine without a valid signal from the Smart Key.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
