1 Tire valve and pressure sensor 2 Tire fitting/removal tool initial start position 3 High tire and bead tension area 4 Low tire and bead tension area When removing the tire, the bead breaker must not be used within 90 degrees of the tire valve in each direction on each side
of the tire.
When using the tire removal machine, the fitting arm start position must be positioned as shown in the tire changing
illustration for each side of the tire. The wheel can then be rotated through 180 degrees in a counter-clockwise direction. This
will relieve tension from the tire bead allowing the remaining 180 degrees of the tire to be manually pulled from the rim.
When refitting the tire, position the fitting arm as shown. Rotate the tire and take care that the bead on the low tension side
of the tire does not damage the sensor.
Run-Flat Tires
Run-flat tires are not available on vehicles from 2011MY.
TREAD Act - NAS Only
Vehicles supplied to the North American markets must comply with the legislation of the Transport Recall Enhancement,
Accountability and Documentation (TREAD) act. Part of the requirement of the TREAD act is for the vehicle to display a label
which defines the recommended tire inflation pressure, load limits and maximum load of passengers and luggage weight the
vehicle can safely carry. This label will be specific to each individual vehicle and will be installed on the production line. The
label is positioned on the driver's side 'B' pillar on NAS vehicles and the inside rear face of the LH door on Canadian
specification vehicles.
This label must not be removed from the vehicle. The label information will only define the specification of the vehicle as it
came off the production line. It will not include dealer or owner fitted accessory wheels and tires of differing size from the
original fitment.
If the label is damaged or removed for body repair, it must be replaced with a new label specific to that vehicle. A new label is
requested from Jaguar parts and will be printed specifically for the supplied VIN of the vehicle.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS) is a driver assistance system which assists the driver to maintain the tire
pressures at the optimum level. TPMS is standard fitment on NAS vehicles and an optional fitment in other markets. TPMS

Specific Steering System Noise Types
Belt Squeal
Belt squeal is a high frequency air-borne noise generated by slippage of the ribbed Vee belt on the power steering pump
pulley. Squeal increases with system loading and at full lock.
Clonk
Clonk is a structure-borne noise heard as a loose-sounding rattle or vibration coming from the steering column. Clonk can be
identified by driving and turning over cobblestones, rough roads, or high frequency bumps such as 25-50 mm tall tar strips.
Clonk requires a tie-rod load impact.
Column Knock
Column knock is a loose-sounding rattle or vibration generated by the steering column shaft contacting other portions of the
column assembly. The noise is both audible and tactile. Column knock is generated by driving over cobblestones or rough
pavement. It is not necessary to turn the steering wheel to create this noise.
Column Rattle
Column rattle is a metallic sounding noise created when applying a highly impulsive force to the steering wheel. Column rattle
is often used to combine the more general group of column noises including clonk and column knock. Column rattle noises can
be caused by clonk, knock, loose column components, bonus parts etc. A series of parked, straight-line driving, and cornering
tests should be carried out to isolate the source/sources.
Grinding/Scrape
Grinding is a low frequency noise in the column when the steering wheel is turned. It is generally caused by interference

1 Fuel supply connection 2 Electrical connector 3 Flange locking ring and seal 4 Sucking jet connector 5 Fuel pump module 6 Fuel pick up filter 7 Level sensor float 8 RH level sensor 9 Fuel filter 10 Pressure relief valve 11 Pump supply to flange connection 12 The fuel pump is a variable speed rotary vane type. The pump is energized by the fuel pump relay which is located in the RJB and the FPDM which is located under the RH floor pan above the rear suspension stabilizer bar. The relay and FPDM are controlled by the ECM.
A fine mesh filter is located in the lower section of the pump module. This provides filtration to the fuel as it is drawn into the
module. There is a winged filter on the fuel pump that gives additional protection and a life time fuel filter integrated into the
flange which eliminates the need for an additional filter further downstream in the fuel system.
The RH fuel level sensor is mounted into the pump module housing.
FUEL PUMP DRIVER MODULE (FPDM)
The FPDM is located on a bracket which is integral with the charcoal canister. The module is attached to one end of the canister with a bracket.
The fuel pump operation is regulated by a FPDM which is controlled by the ECM. The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (pulse width modulation) output.
The FPDM is powered by a supply from the fuel pump relay in the RJB. The fuel pump relay is energized on opening the driver's door, pressing the start button only or pressing the start button and the footbrake (which initiates engine cranking). The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump and thus the pressure and flow
in the fuel delivery line.
A PWM signal from the ECM tells the FPDM the required speed for the fuel pump. The on time of the PWM signal represents half the fuel pump speed, e.g. if the PWM signal has an on time of 50%, the FPDM drives the pump at 100%.
The FPDM will only energize the fuel pump if it receives a valid PWM signal, with an on time of between 4% and 50%. To switch the fuel pump off, the ECM transmits a PWM signal with an on time of 75%.
The output pressure from the fuel pump will change with changes of engine demand and fuel temperature. The ECM monitors the input from the fuel rail LP sensor and adjusts the speed of the fuel pump as necessary to maintain a nominal output
pressure of 450 kPa (4.5 bar; 65.3 lbf/in.2
), except during engine start-up. At engine start-up the target pressure for the fuel
delivery line is 630 kPa (6.3 bar; 91.4 lbf/in.2
).
If the SRS (supplemental restraint system) outputs a crash signal on the high speed CAN (controller area network), the ECM de-energizes the fuel pump relay to prevent any further fuel being pumped to the engine.
If the ECM does not detect pressure in the fuel delivery line, it stops, or refuses to start the engine and stores the appropriate DTC (diagnostic trouble code).
The ECM receives a monitoring signal from the FPDM. Any DTC's produced by the FPDM are stored by the ECM.
DTC's can be retrieved from the ECM using an approved Jaguar diagnostic system. The FPDM itself cannot be interrogated by the approved Jaguar diagnostic system.

EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the
total distance is not lost if the battery is disconnected.
The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.

Warning Devices - Blindspot Monitoring System - Overview
Description and Operation
OVERVIEW Published: 11-May-2011
Eliminating blind spots is a major element in vehicle body design, but because of the structural requirements of B, C and D
posts, blind spots cannot be entirely eliminated. Statistics show that some accidents are directly attributable to drivers moving
across into the path of overtaking vehicles that have not been seen in conventional mirrors. New mirror designs have improved
the situation, but by remotely covering areas that cannot be seen either directly or by the vehicle mirrors, have led to the
introduction of a radar-based blind spot monitoring system.
The blind spot monitoring system comprises:
LH (left-hand) Blind spot monitoring sensor
RH (right-hand) Blind spot monitoring sensor
LH door mirror RH door mirror
The system uses two radar modules operating at a frequency of 24 GHz and each combining the radar face and electronic
module in a single unit. The modules are located behind the rear bumper surface, symmetrically, one on each side of the car
behind the rear wheels. They are side facing and inclined rearwards at an angle of 16 degrees, which is dictated by the shape
at the rear of the vehicle. Each module is calibrated to detect a vehicle in the driver’s blind spot. Once a vehicle is detected
the module illuminates an amber warning ‘alert icon’ LED (light emitting diode) in the relevant exterior door mirror. If there is a
fault or blockage with the blind spot monitoring system an amber warning indicator dot LED is displayed in the exterior mirror and the message ‘blind spot monitoring not available’ is displayed in the instrument cluster message center.
When the system initiates, it performs a self-check, during which the warning icons in the mirrors illuminate alternately for a
short period of time. Each module does a left/right determination check when the ignition is switched on. Each mirror has a
different circuit configuration so that the modules can determine which mirror they are connected to. If a module detects the
wrong mirror it will go into a fault condition.
The blind spot monitoring modules receive vehicle speed on the medium speed CAN (controller area network) and are inactive
until the vehicle reaches 16kph (10mph). Each blind spot monitor module emits a radar field greater than the blind spot area.
Each Blind Spot Monitor module emits a radar field greater than the blind spot area. The actual blind spot area is calibrated
into the module during its manufacture.
CAUTION: The blind spot monitoring system is designed as a driver aid not a safety device. The driver should always
exercise due care and attention whilst driving. www.JagDocs.com
Page 1834 of 3039
Blind Spot Monitoring System Operation
The purpose of the blind spot monitoring system is to detect an object moving with a positive velocity relative to the radar
module, on either side of the vehicle, at a distance of up to 2.5 meters laterally and in an area from the door mirror up to 7.0
meters behind the module. These criteria identify an overtaking vehicle within the blind-spot area and within a typical
carriageway lane width, while eliminating other objects that are not relevant, either because of their position, they are
stationary, traveling in the opposite direction, or being overtaken. A vehicle is classed as a heavy goods vehicle, car or
motorcycle. A motorcycle is defined as a minimum size of 2.0m long, 0.8m wide (widest point) and 1.1m high. The system is
not affected by the mass of the overtaking vehicle providing all identification criteria, including relative velocity of (16km/h -
10mph) or above, is met.
The system emits radar pulses and analyses the reflections, identifying anything that moves into the blind spot zone. Having
detected another vehicle in the defined blind spot zone it alerts the driver by illuminating the amber alert icon located in the
appropriate exterior mirror.
NOTE: If an overtaking vehicle is detected on both sides of the vehicle simultaneously, the warning alert icons in both
mirrors will illuminate.
The light lens is shaped so as to minimize the visibility to other drivers. The LED (light emitting diode)’s are located towards
the outside extremity of the mirror face, within the peripheral view of the driver but not in any area of the mirror where they
could obscure or distract from the image.
Item Description 1 Warning alert icon 2 System status warning indicator The LED lighting sequence is as follows;
Amber alert LED icon permanently lit - system operational, vehicle detected in blind spot area No LED’s lit – system active no vehicle detected in blind spot area Amber status LED permanently lit - system not active or faulty
The system has operating limitations and is automatically turned off under certain operating conditions. During these
operating conditions the amber status LED is permanently lit. The system operating limitations are as follows;
The area surrounding the radar face of the module must be clear of metallic items
The system is inactive until vehicle speed is greater than 16km/h - 10mph (amber status LED permanently lit) The system is inactive if an approved trailer is connected to the vehicle (amber status LED permanently lit) The system is inactive when reverse gear or park is selected (amber status LED permanently lit)
If either of the radar signals are blocked or distorted, for example by water, the radar face of the module is covered in mud,
sleet or snow the system may detect this and be disabled with the amber status LED permanently lit together with a ‘blind spot monitoring blocked’ message displayed in the instrument cluster message center. The system is disabled until the
blockage is cleared.
If there is a fault in the system the amber status LED is permanently lit and a ‘blind spot monitoring not available’ message displayed in the instrument cluster message center. The system is disabled until the fault is rectified.
System fault and blockage warnings are as follows;

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.
Jaguar Quiescent Drain Values

5. NOTE: Where fitted.
6. NOTE: This step is only necessary when installing a new
component.
Using the Jaguar approved diagnostic equipment, reset the battery
monitoring system.
7. Refer to: Door Window Motor Initialization (501-11 Glass, Frames and Mechanisms, General Procedures).
8. Enter the audio unit preset radio frequencies.
9. Reset the clock to the correct time.
10. Start the engine and allow to idle until the engine reaches normal
operating temperature.
11. Switch the engine off.
