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.

The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN (local interconnect network) bus connection from the RJB which is not used at the moment but installed for a later enhancement of the parking aid camera.
A shielded co-axial cable connection between the camera and the Touch Screen Display (TSD) is used for the video image
transmission.
The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected signal on the medium speed CAN bus message to the entertainment system control module. This message is transferred on the MOST to the TSD which displays the parking aid camera video input from the camera in
preference to the parking aid alert screen.
If the driver does not require the camera image in the TSD, a single touch on the screen will revert the display to the parking
aid alert screen. The camera view can be reselected by pressing the 'Rear Camera' softkey on the TSD.
When reverse gear is deselected, the camera image remains on the TSD for 10 seconds after the transmission has been put
into drive 'D'. This is to prevent the TSD switching between screens if the vehicle is being manoeuvred into a parking space. If
the vehicle forward speed exceeds 16 km/h (10 mph) within the 10 second period, the camera image is removed from the TSD.
If the TSD display is switched off, the camera image will be automatically displayed when reverse gear is selected. When
reverse gear is deselected and the 10 second period has expired, the TSD will revert back to its switched off state.
PARKING AID
Parking Aid Module Component Description
The parking aid module is located on the LH side of the luggage compartment.
The parking aid module has three connectors which provide for power, ground and CAN bus connections, front parking aid sensors and rear parking aid sensors. The medium speed CAN bus connections provide for the receipt of the following Distance Calculation

PARKING AID CAMERA
The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN bus connection with the RJB, which is used as a gateway. A shielded co-axial cable connection between the camera and the TSD is used for the video image transmission.
The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected message on the medium speed CAN bus. The information and entertainment module transfers the message on the MOST ring to the TSD, which displays the video input from the parking aid camera in preference to the parking
aid alert screen.
The display from the camera incorporates graphic overlays, indicating vehicle direction, width and proximity to surrounding
objects.
Item Description A Solid line: The projected wheel trajectory B Dotted line: The safe working width of the vehicle (including exterior mirrors) C Luggage compartment access guideline: Do not reverse beyond this point if luggage compartment access is required D Bumper inclusion E Parking sensor activation: A colored area appears, to indicate which rear sensors have been activated A single touch on the screen will revert the display to the parking aid alert screen. The camera view can be reselected by
pressing the Rear Camera soft key on the TSD.
NOTE: This can only be activated when reverse gear is selected.
When reverse gear is deselected, the camera image remains on the TSD for 2 seconds after the transmission has been put into
D (drive). If the vehicle forward speed in D exceeds 16 km/h (10 mph) the camera image is removed from the TSD.
If the TSD is switched off, the camera image will be automatically displayed when reverse gear is selected. When reverse gear
is deselected, after 10 seconds the TSD will revert back to its switched off state.

Battery and Charging System - General Information - Battery Care
Requirements
Description and Operation
1. INTRODUCTION
This document defines the requirements for care and maintenance of batteries, and the standard of battery care at dealers and
retailers for new vehicles.
This applies to all types of 12 Volt Lead Acid Batteries used in Jaguar and Land Rover vehicles whether they are conventional
flooded technology or Absorbed Glass Mat (AGM – also known as Valve Regulated Lead Acid (VRLA)) technology and also
applies to both Primary, Secondary and Auxiliary Batteries. AGM batteries offer improved resistance to cycling as seen in stop
start applications.
In order to prevent damage to the battery and ensure a satisfactory service life, all processes detailed within this document
must be rigorously adhered to.
It is equally important therefore to note the following key points:
All new vehicles leave the factory with either a transit relay installed and/or have a transit mode programmed into the
vehicle control modules. The transit relay must be removed and the transit mode disabled (where applicable) using an
approved diagnostic system, NOT MORE THAN 72 HOURS before the customer takes delivery.
The battery can be discharged by the following mechanisms:
- Self Discharge: - A lead acid battery will very slowly discharge itself due to its own internal chemical processes
whether it is connected to a vehicle or not.
- Quiescent Discharge: - The vehicle electrical systems when connected to the battery will draw charge from the
battery.
12 Volt Lead Acid Batteries rely on internal chemical processes to create a voltage and deliver current. These processes and
the internal chemical structure of the battery can be damaged if the battery is allowed to discharge over a number of weeks /
months, or is left in a discharged state for a lengthy time period.
On vehicles with conventional ignition keys, these must not be left in the ignition lock barrel when the transit relay
has been removed, otherwise quiescent current will increase and the battery will discharge more rapidly.
For keyless vehicles, the Smart Key must be stored at least 5m (16 ft) away from the vehicle when the vehicle is
parked or stored.
AGM Batteries are fully sealed and cannot have the electrolyte level topped up.
NOTE: Dealers and retailers involved in the storage / handling of vehicles and replacement batteries have a responsibility
to ensure that only a fully charged battery may be processed through the distribution selling chain.
2. GENERAL RULES FOR BATTERY CARE
2.1 Dealer Demonstration Vehicles
Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a JLR approved showroom conditioner capable
of delivering 50 Amps. This will prevent the battery from being damaged.
2.2 Software Reflash, SDD work or Ignition On related workshop activities
Due to the high electrical current demand and high depth of discharge that can occur during vehicle software re-flash activities,
SDD work or ignition on (power mode 6) related work in the workshop, vehicles that are undergoing such activities MUST have a
JLR approved power supply capable of delivering 50 Amps or more.
2.3 Extended Vehicle Rework
For any extended vehicle rework that results in consuming vehicle power, either the battery should be disconnected or a JLR
approved power supply connected.
2.4 Jump Starting New vehicles before they have been delivered to the customer
It is the dealer / retailers responsibility to make sure the battery is not allowed to discharge by following the
instructions and processes defined in this manual.
However, if circumstances dictate that a new vehicle must be jump started due to a discharged battery whilst the
vehicle is in the dealer / retailers care, the battery on this vehicle must be replaced with a new one prior to delivery
to the customer at the dealer / retailers liability.
The vehicle should also undergo investigation as to why the battery became discharged.
Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended
earth point. As defined in the owners handbook or service documentation for that vehicle. 2.5 AGM Batteries
AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
AGM Batteries must be tested with a capable battery tester as detailed in the Equipment section (Section 5) of this

Battery and Charging System - General Information - Quiescent Drain
Description and Operation
VEHICLE QUIESCENT CURRENT TESTING
On vehicles fitted with a Battery Monitoring System (BMS), the diagnostic routine for quiescent drain testing in the approved
Jaguar or Land Rover diagnostic system should be utilized.
If a customer complains of a vehicle battery that discharges continuously or when left for a prolonged period of time, it is
recommended that a quiescent drain test is performed as described below.
The battery drain should be measured using the approved Jaguar or Land Rover diagnostic system or a Digital Multi-Meter
(DVOM). A procedure for quiescent drain measurement using the diagnostic system is available in the Diagnosis and Testing
section of the Workshop Manual. The vehicle should be in the locked/armed state (for example vehicle alarm fully armed), all
doors, engine and luggage compartment lids are open and latched (so as to appear closed from an electrical point of view).
The test should take place after the vehicle has entered shutdown mode. The time taken for this to occur after the ignition is
switched off varies according to model (Refer to the Topix On line resource for details).
When the vehicle is armed, the effect of the security system Light Emitting Diode (LED) flashing is to cause a pulsation in the
measured current drain. In this case, either the average current should be taken (using a Digital Multi- Meter (DVOM) with an
averaging system) or the current reading taken, ignoring the brief high current peaks.
EQUIPMENT
Approved Jaguar or Land Rover diagnostic system with current probeOR Digital Multi-Meter (DVOM) with current probe.
METHOD OF MEASUREMENT
Using an Approved Jaguar or Land Rover Diagnostic System.
1. Switch off all electrical loads and ensure that the ignition is off
2. Connect the current probe to the approved Jaguar or Land Rover diagnostic system
3. Calibrate the probe
4. Install a clamp around the battery lead/junction box lead
5. Go to the Quiescent Current Testing section in this procedure
Using a digital multimeter
Do not use an in-line DVOM to measure the quiescent drain on vehicles fitted with an electronic throttle (for example XK 2006
onwards). The current exceeds the maximum amount the fuse in the DVOM is capable of handling.
1. Switch off all electrical loads and ensure that the ignition is off
2. Connect the current probe to the digital multmeter
3. Calibrate the probe
4. Install a clamp around the battery lead/junction box lead
5. Go to the Quiescent Current Testing section in this procedure
QUIESCENT CURRENT TESTING
1. Switch ignition to ‘on’ or select ignition mode in keyless vehicles and switch to ‘off’ (do not crank)
2. Remove key from ignition switch (if equipped)
3. Open and latch all doors, hood and luggage compartment lid
4. Lock the vehicle using the remote function on the remote handset. (Single lock only to avoid volumetric alarm arming)
5. Remove any other potential electrical drains such as accessories plugged into accessory sockets
6. Record the amperage readings after the shutdown period referenced in the Topix on line resource for details. Note all
cars from 10MY onwards and XK from 07MY and XF from 08MY should be less than 30mA after 30 minutes
7. Record the final reading on the battery report form
The preferred method of testing following an excessive current consumption figure is to use a current probe around individual
junction box leads to the various suspected circuits to identify a potential cause. This is in preference to the old method of
removing fuses for the following reasons:
The drain may be caused by a module remaining active and preventing the quiescent drain from reducing to normal
levels
The drain may be caused by a relay winding that is activated. Pulling the fuse can allow this to ‘reset’ and the drain will
be lost and go un-diagnosed
QUIESCENT DRAIN - TYPICAL VALUES
NOTE: The quiescent drain after the initial shutdown period should not exceed the value shown in the table.
