Item Description 1 LH turn signal 2 RH turn signal 3 Brake warning 4 Brake warning (NAS) 5 Forward alert 6 Automatic Speed Limiter (ASL) 7 Adaptive speed control 8 ABS (anti-lock brake system) warning 9 ABS warning (NAS) 10 Malfunction Indicator Lamp (MIL) 11 Tire Pressure Monitoring System (TPMS) 12 Airbag warning 13 Front fog lamps 14 Dynamic Stability Control (DSC) warning 15 Seat belt warning 16 Side lamps 17 High beam 18 Rearfoglamps

6. Adaptive Speed Control Indicator
The adaptive speed control system is controlled by the adaptive speed control module. Operation of the SET +/- switches on
the steering wheel will activate the system. Operation of the switches is detected by the adaptive speed control module. The
module issues a high speed CAN message to the instrument cluster which illuminates the adaptive speed control indicator, when the system is in 'follow mode', in an amber color and displays a 'SETSPEED XXX MPH / KM/H' message in the message
center. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
7. Anti-lock Braking System (ABS) Warning Indicator

The ABS warning indicator is controlled by the ABS module. If a fault in the ABS system is detected by the ABS module, the module issues a high speed CAN message to the instrument cluster to illuminate the ABS warning indicator in an amber color and display the message 'ABS FAULT' in the instrument cluster. The indicator is illuminated in an amber color for a 3 second
indicator check when the ignition is switched on. If a fault is present when the ignition is on, the bulb will remain illuminated
after the 3 second indicator check period.
NOTES:


The 'ABS FAULT' message is not displayed in NAS markets).


If both the ABS warning indicator and the brake warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.

On NAS vehicles, the ABS warning indicator is also used for parking brake operation. The NAS warning indicator does not have 'ABS' on the icon and will function as described previously for the parking brake operation of the brake warning indicator.
8. Engine Malfunction Indicator Lamp (MIL)

The MIL warning indicator is controlled by the ECM and illuminated by the instrument cluster on receipt of a message on the high speed CAN bus from the ECM. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the MIL remains illuminated after the engine is started or illuminates when driving, a fault is present and must be
investigated at the earliest opportunity. Illumination of the MIL warning indicator alerts the driver to an OBD (on-board
diagnostic) fault which will cause excessive emissions output. This may relate to either an engine management system fault or
a transmission.
9. Tire Pressure Monitoring System (TPMS) Warning Indicator

The TPMS warning indicator is illuminated by the instrument cluster on receipt of a medium speed CAN message from the TPMS module. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the indicator illuminates and is accompanied by the message 'TYRE PRESSURE SYSTEM FAULT' in the message center, then a
TPMS fault has occurred. If the indicator illuminates and accompanied by a different message, then a low tire pressure has
been detected, a spare wheel has been fitted or a TPMS sensor has failed.
10. Airbag Warning Indicator

The airbag warning indicator is controlled by the instrument cluster. The indicator is illuminated in an amber color for the 3
second indicator check when the ignition is switched on. The indicator remains illuminated after the 3 second period has
expired until the instrument cluster receives a turn off message on the high speed CAN bus from the RCM (restraints control module).
11. Front Fog Lamp Indicator

The green colored front fog lamp indicator is controlled by the CJB and illuminated by the instrument cluster on receipt of a front fog lamp on message on the medium speed CAN bus from the CJB. The indicator is illuminated for as long as the front fog lamps are active. The front fog lamp indicator is not subject to the 3 second indicator check when the ignition is switched
on.
12. Dynamic Stability Control (DSC) Indicator

The DSC warning lamp is controlled by the ABS module and illuminated by the instrument cluster in response to messages received on the high speed CAN bus. The indicator is illuminated in an amber color for the 3 second indicator check when the ignition is switched on. The DSC warning indicator, are permanently illuminated in an amber color if the instrument cluster
receives a high speed CAN message from the ABS module relating to one of the following faults:
Traction control fault
Yaw control fault
Engine drag torque control fault
Panic Brake Assist (PBA) fault
Signal missing relating to either traction control active, yaw control active or DSC switch input.

The above faults will also generate an applicable DSC and ABS warning message in the message center. The DSC warning
indicator will flash at 2 Hz for if the traction control or yaw control is active when the DSC system is enabled. If the DSC
system is switched off, the warning indicator will be permanently illuminated until the DSC system is subsequently
re-activated.

13. Safety Belt Warning Indicator

The safety belt warning indicator operates for both the driver and passenger safety belts. The warning indicator is controlled by

Description and Operation

System Operation
SERVICE INTERVAL INDICATOR - 3.0L V6 DIESEL, 5.0L V8 SUPERCHARGER AND 5.0L V8 NATURALLY ASPIRATED ENGINES ONLY

If the vehicle is within 3,200 kilometers (1,988 miles) of a service, the message center will display 'SERVICE REQUIRED IN
XXXX km or MILES'. The display reduces the 'service required in' readout by increments every 50 kilometers (30 miles). If this
distance drops below 1 km (0.6 miles), the message center will display 'SERVICE REQUIRED'.

These messages are displayed every time the vehicle enters power mode 6, for 4 seconds after the instrument cluster bulb
check routine has finished.


NOTE: The message center will display distance to next service in miles on an instrument cluster fitted with a Miles Per
Hour (MPH) speedometer unless the driver has changed the display units on the Touch Screen Display (TSD).
Reset Procedure
To re-set the service interval indicator, the following process switch presses must each be carried out within 3 seconds:
With the vehicle in power mode 0, (ignition off) press and hold the rear fog lamp switch
Allow the vehicle to enter power mode 6 (Press the start button without a foot on the brake)
Immediately release the rear fog lamp switch
Press and hold the trip computer cycle switch
Press and hold the rear fog lamp switch
Continue to hold the trip computer and rear fog lamp switches
If the process has been successful, the message center will display 'RESETTING SERVICE MODE' and then display
'SERVICE MODE RESET' after 10 seconds
Release both switches and return the vehicle ignition to off, power mode 0.



MESSAGE CENTER Component Description

The message center LCD (liquid crystal display) display has a viewable area of 126 pixels horizontal and 174 pixels vertical. It
is divided into six information display zones as follows, starting from the top:

Set speed
Transmission position
Warning /message display
JaguarDrive Optimization icon
Odometer/Trip computer information
Fuel level.

The message center is active at all times when the ignition is on and can also be active when the ignition is off, dependant on
the information to be displayed. The message center LCD illumination is controlled by the sun load light sensor located on the instrument panel. In bright conditions, the illumination is set to maximum brightness. As the ambient light levels drop, the
illumination dims. When the lights are switched on or activated by the 'AUTO' function, the illumination operates in the same
way until a defined ambient light threshold is reached, at this point the setting of the panel illumination dimmer in the
auxiliary light switch will control the brightness.

If more than one message is active, each message is displayed for 4 seconds in the order of priority. Once all messages have
been displayed, they are again displayed in turn for 2 seconds each. Warning messages can be displayed when the ignition is
in accessory power mode 4 which is the initial ignition state when a door is opened.
Message Priority

Messages are assigned priorities which are defined by the effect on driving safety and functional ability of the vehicle. When
new messages are displayed they may be accompanied by a chime from the instrument cluster sounder. A new message will be
displayed immediately, providing the currently displayed message (if there is one) has been displayed for at least 4 seconds. A
warning indicator will be activated simultaneously with the message being displayed. If more than one fault warning message
is being displayed, the messages will cycle, in priority order, with each message being displayed for 2 seconds.

INFORMATION DISPLAY

The transmission display is located in the upper section of the LCD. The transmission position information is sent from the TCM (transmission control module) in a high speed CAN (controller area network) message to the instrument cluster. The
transmission has three modes of operation:

Conventional automatic operation (JaguarDrive selector in 'D' position)
Sport automatic operation (JaguarDrive selector in 'S' position)
Manual gear operation - Jaguar Sequential Shift.
