module and fuel injector operating data from the ECM.
A 'Trip' button is located on the end of the LH (left-hand) multifunction switch and allows the driver to access, in sequence, the
available trip information by repeatedly pressing the button. The trip information is displayed in the following order:
Trip distance – The trip distance since the last reset is displayed
Average speed – The average speed since the last reset is displayed
Average fuel consumption – The average fuel consumption since the last reset is displayed
Range – The range is displayed showing the distance which can be travelled until the fuel gage reads empty. If the
range display shows dashes (-), this indicates a failure with one or both of the fuel level sensors.
The trip computer has three independent memories; A, B and Auto. Memories A and B can be set independently. The Auto
memory is reset after each ignition cycle and therefore only contains information relating the current journey.
The trip information can also be accessed from the TSD located in the center console. The TSD allows the same information
available with the trip button on the multifunction switch to be displayed on the TSD, with the addition of the option to reset
the values in the A and B memories.
If the battery is disconnected, all trip data in memories A, B and Auto are erased.
Fuel Level Display
The fuel level display is a linear LCD display to show the usable fuel tank contents. The level display is active at all times when the ignition is on. Low fuel level is displayed as a LOW FUEL LEVEL message and an amber warning triangle in the
message center.
The fuel level is obtained by fuel level sensors in the fuel tank. These are monitored by the RJB software and their output resistance values, corresponding fuel quantity, are transmitted to the instrument cluster on the medium speed CAN bus. The instrument cluster uses the two level sensor signals to calculate the fuel tank contents. This calculation takes into account
fuel movement in the tank to display a steady fuel quantity in the LCD.
The fuel level information is transmitted on the medium speed and high speed CAN bus for use by other vehicle system modules.
AUDIBLE WARNINGS
The instrument cluster can generate audible warnings to alert the driver to a displayed message and change of vehicle
operating condition. The audible warning is generated by a sounder located within the instrument cluster. The audible warnings
can be generated for the warnings below and are listed in order of priority, with the first being the highest priority:
Seatbelt reminder
EPB (High Pitch)
ACC Driver Intervene 1
Airbag fault
Key in ignition switch
ASL overspeed
ACC Driver Intervene 2
EPB (Low Pitch)
Vehicle armed (entry delay)
JaguarDrive selector not in park
Valet mode
Lights on reminder
Hood operation
Passive Entry / Passive Start (PEPS)
Memory set
Turn signal indicators
Seat Belt Minder.
The audible warnings can take the form of a single chime, a number of chimes or a continuous chime. The audible warnings are
initiated by a CAN message request from the requesting sub-system control module or by the instrument cluster software.

Daytime Running Lamps (DRL) - Daytime Running Lamps (DRL) - System
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.
