WARNINGS:

EYE CONTACT: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes. Wash hands thoroughly
after handling. If brake fluid comes into contact with the eyes, flush the eyes with plenty of cold running water for 15 minutes.
Seek medical attention for any persistent eye irritation or abnormality.


SWALLOWED: Brake fluid contains polyglycol ethers and polyglycols. If swallowed, drink plenty of water. Seek immediate
medical attention.


INHALED: Dust from friction materials can be harmful if inhaled.
Only use new specified brake fluid from airtight containers.
CAUTION: If brake fluid is spilled on the paintwork, the affected area must be immediately washed down with cold water.

Do not empty fuel while working in a workshop or a pit
Ensure that working area is well ventilated
Ensure that any work on the fuel system is only carried out by experienced and well qualified maintenance personnel
Ensure that fume extraction equipment is used where appropriate


Fume extraction equipment must be in operation when solvents are used e.g. Trichloroethane, white spirit, sbp3,
methylene chloride, perchlorethylene. Do not smoke in the vicinity of volatile degreasing agents.

Whenever possible, use a ramp or pit whilst working beneath a vehicle, in preference to jacking. Position chocks at the wheels
as well as applying the parking brake. Never rely on a jack alone to support a vehicle. Use axle stands, or blocks carefully
placed at the jacking points, to provide a rigid location. Check that any lifting equipment used has adequate capacity and is
fully serviceable. Ensure that a suitable form of fire extinguisher is conveniently located. When using electrical tools and
equipment, inspect the power lead for damage and check that it is properly earthed. Disconnect the earth (grounded) terminal
of the vehicle battery. Do not disconnect any pipes of the air conditioning refrigeration system unless you are trained and
instructed to do so. A refrigerant is used which can cause blindness if allowed to come into contact with the eyes. Ensure that
adequate ventilation is provided when volatile degreasing agents are being used.

Adhere strictly to handling and safety instructions given on containers and labels. Keep oils and solvents away from naked
flames and other sources of ignition. Do not apply heat in an attempt to free seized nuts or fittings; as well as causing
damage to protective coatings, there is a risk of damage from stray heat to electronic equipment and brake lines. Do not leave
tools, equipment, spilt oil etc. around the work area. Wear protective overalls and use barrier cream when necessary.

Environmental Protection

In some countries it is illegal to pour used oil onto the ground, down sewers or drains, or into water courses. The burning of
used engine oil in small space heaters or boilers is not recommended unless emission control equipment is installed. Dispose
of used oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation
trade. If in doubt, contact the Local Authority for advice on disposal facilities.

Description and Operation

Protecting the Vehicle Published: 04-Jul-2014

Always install covers to protect the fenders before commencing work in the engine compartment. Always install the interior
protection kit, wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic
fluid, antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use polythene
sheets in the luggage compartment to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or installing caps.

Vehicle in Workshop

When working on a vehicle in the workshop always make sure that:

The parking brake is applied or the wheels are securely chocked to prevent the vehicle moving forwards or backwards
If the engine is to be run, there is adequate ventilation, or an extraction hose to remove exhaust fumes is installed
There is adequate room to jack up the vehicle and remove the wheels, if necessary
Fender covers are always installed if any work is to be carried out in the engine compartment
The battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle is jacked up


CAUTION: When electric arc welding on a vehicle, always disconnect the generator wiring to prevent the possibility of a
surge of current causing damage to the internal components of the generator.
If using welding equipment on the vehicle, ensure a suitable fire extinguisher is readily available.

Screw Threads

Damaged nuts, bolts and screws must always be discarded. Attempting to recut or repair damaged threads with a tap
or die impairs the strength and fit of the threads and is not recommended.
NOTES:

During certain repair operations, it may be necessary to remove traces of thread locking agents using a tap. Where this
is necessary, the instruction to do so will appear in the relevant operation and it is essential that a tap of the correct size and
thread is used.


New Taptite bolts when used cut their own threads on the first application.

Some bolts are coated with a thread locking agent and unless stated otherwise, they must not be reused. New bolts
having the same part number as the original must always be installed. When nuts or bolts are to be discarded, the
repair operation and relevant torque chart will include an instruction to that effect. Do not use proprietary thread
locking agents as they may not meet the specification required. See also Encapsulated ('Patched') Bolts and Screws.
Always make sure that replacement nuts and bolts are at least equal in strength to those that they are replacing.
Castellated nuts must not be loosened to accept a split pin except in recommended cases when this forms part of an
adjustment.
Do not allow oil or grease to enter blind holes, the hydraulic action resulting from tightening the bolt or stud can split
the housing and also give a false torque reading.
Always tighten a nut, bolt or screw to the specified torque figure, damaged or corroded threads can give a false torque
reading.
Nut and bolt loosening and tightening sequences, where given, must ALWAYS be followed. Distortion of components or
faulty sealing of joints will result if the sequences are not followed. Where an instruction is given to tighten in stages,
these stages must be adhered to; do not attempt to combine stages particularly where certain stages involve
tightening by degrees.
To check or re-tighten a fixing to a specified torque, first loosen a quarter of a turn, then retighten to the specified
torque figure.
Unless instructed otherwise, do not lubricate bolt or nut threads prior to installing.
Where it is stated that bolts and screws may be reused, the following procedures must be carried out:
Check that threads are undamaged.
Remove all traces of locking agent from the threads.

CAUTION: DO NOT use a wire brush; take care that threads are not damaged.
Make sure that threads are clean and free from oil or grease.
Apply the specified locking agent to the bolt threads.

Jacking and Lifting - Jacking
Description and Operation

Safety Precautions Published: 11-May-2011

WARNING: The jack provided with the vehicle is intended to be used in an emergency for changing a deflated tire. To
avoid damage to the vehicle, never use the jack to raise the vehicle for any other purpose. Refer to the Driver Handbook when
using the jack supplied with the vehicle. Failure to follow these instructions may result in personal injury.
The following safety precautions must be observed when raising the vehicle to carry out service operations:
Never rely on a jack alone to support a vehicle. Always use suitable vehicle stands to provide rigid support.
When working beneath a vehicle, whenever possible use a vehicle hoist instead of a jack and vehicle stands.
Make sure that the vehicle is standing on firm, level ground before using a jack.
Do not rely on the parking brake alone; chock the wheels and put the automatic transmission into Park if possible.
Check that any lifting equipment used has adequate capacity for the load being lifted and is in correct working order.

Noise Conditions

Gear noise is typically a howling or whining due to gear damage or incorrect bearing preload. It can occur at various
speeds and driving conditions, or it can be continuous
Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning bicycle wheel. It occurs
while decelerating from approximately 64 km/h (40 miles/h) and can usually be heard all the way to a stop. The
frequency varies with vehicle speed
Knock is very similar to chuckle, though it may be louder and occurs on acceleration or deceleration. The tear down will
disclose what has to be corrected
Check and rule out tires, exhaust and trim items before disassembling the transmission to diagnose and correct gear noise.

The noises described under Road Test usually have specific causes that can be diagnosed by observation as the unit is
disassembled. The initial clues are the type of noise heard on the road test and the driving conditions.

Vibration Conditions


wear. NOTE: New Constant Velocity (CV) joints should not be installed unless disassembly and inspection revealed unusual

Clicking, popping or grinding noises may be caused by the following:

Cut or damaged CV joint boots resulting in inadequate or contaminated lubricant in the outboard or inboard CV joint
bearing housings
Loose CV joint boot clamps
Another component contacting the rear drive half shaft
Worn, damaged or incorrectly installed wheel bearing, suspension or brake component
Vibration at highway speeds may be caused by the following:
Out-of-balance front or rear wheels
Out-of-round tires
Driveline imbalance
Driveline run-out (alignment)


NOTE: Rear drive half shafts are not balanced and are not likely to contribute to rotational vibration disturbance.
Shudder or vibration during acceleration (including from rest) may be caused by the following:
Driveline alignment
Excessively worn or damaged outboard or inboard CV joint bearing housing
Excessively high CV joint operating angles caused by incorrect ride height. Check ride height, verify correct spring rate
and check items under Inoperative Conditions
Excessively worn driveshaft components

Leakage Conditions

1. Inspect the CV joint boots for evidence of cracks, tears or splits.

2. Inspect the underbody for any indication of grease splatter in the vicinity of the rear drive half shaft, outboard and
inboard CV joint boot locations, which is an indication of CV joint boot or CV joint boot clamp damage.
3. Inspect the inboard CV joint bearing housing seal for leakage.

Inoperative Conditions

If a CV joint or rear drive half shaft pull-out occurs, check the following:

suspension components for correct location, damage or wear
bushings for wear
subframe for damage
bent or worn components
- Stabilizer bar link
- Left-hand rear suspension lower arm and bushing
- Right-hand rear suspension lower arm and bushing
- Rear wheel hub and rear drive half shaft

Road Test

A gear-driven unit will produce a certain amount of noise. Some noise is acceptable and may be audible at certain speeds or
under various driving conditions as on a newly paved blacktop road. The slight noise is in no way detrimental and must be
considered normal.

The road test and customer interview (if available) provide information needed to identify the condition and give direction to
the correct starting point for diagnosis.
1. Make notes throughout the diagnosis routine. Make sure to write down even the smallest piece of information, because

PRINCIPLES OF OPERATION System Operation

The adaptive damping module uses a combination of information from other system modules and data from the accelerometers
and suspension height sensors to measure the vehicle and suspension states and driver inputs. Using this information, the
adaptive damping module applies algorithms to control the dampers for the current driving conditions.
The adaptive damping module receives signals on the high speed CAN bus from the following system components: Brake Pressure - ABS module. Brake Pressure Quality Factor - ABS module. Car Configuration Parameters - AJB. Center Differential Range Actual - ECM. Engine Speed - ECM. Engine Speed Quality Factor - ECM. Engine Torque Flywheel Actual - ECM. Engine Torque Flywheel Actual Quality Factor - ECM. Gear Position Target - TCM. Lateral Acceleration - ABS module. Power Mode (Ignition Signal) - CJB. Power Mode Quality Factor - CJB. Roll Stability Control Mode - ABS module. Steering Wheel Angle - ABS module. Steering Wheel Angle Speed - ABS module. Steering Wheel Angle Status - ABS module.

Rear Left Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed - ABS module. The adaptive damping module also outputs information on the high speed CAN bus for use by other systems as follows: Fault Message - instrument cluster.
Terrain Mode Change Status - JaguarDrive selector.
Terrain Mode - JaguarDrive selector.

The adaptive damping module monitors the input signals and operates the damper solenoids. The input signals are used in
control modes and a force required for each damper for that mode is calculated. An arbitration mode monitors the force
requirements from each mode and apportions a force to a damper. The force is converted to the appropriate current and sent to
the damper.
The control modes are as follows:

Description and Operation



JAGUARDRIVE CONTROL OPERATION

Engine Management System System Operation

The Engine Management System (EMS) varies the accelerator pedal maps to change the amount of torque per percentage of
pedal travel. The EMS can also change the accelerator pedal response to control the allowed torque change relative to the
speed of pedal travel.

Each driving mode uses a combination of operating parameters for each sub-system. Changing between driving modes initiates
a different set of operating characteristics, which will be noticeable to the driver. The driver will notice differences in engine
response when, for example, the accelerator pedal is held in a constant position and the driving mode is changed from Winter
to Dynamic, the driver will notice the torque and engine speed increase. Similarly, if the mode is changed from Normal or
Dynamic to Winter the driver will notice a reduction in torque and engine speed.


NOTE: The change in torque and engine speed can take approximately 30 seconds and care must be taken not to confuse
the JaguarDrive Control system operation with an EMS fault.
Transmission Control

The TCM (transmission control module) changes the shift maps for the JaguarDrive Control mode selected. This changes the
shift points providing early or late upshifts and downshifts. For example, on slippery surfaces in Winter mode the transmission
will select 2nd gear for starting from a standstill on a flat surface to minimize wheel slip.
Anti-lock Braking System Control

The ABS (anti-lock brake system) module controls several vehicle functions and adjusts the operating parameters of these
functions to optimize the selected JaguarDrive Control mode. Traction control uses different slip/acceleration thresholds to
improve traction and vehicle composure. For example, the system sensitivity is increased on slippery surfaces to reduce wheel
spin.

If TracDSC is selected or DSC is switched off, then subsequently the JaguarDrive Control mode is changed, DSC is automatically
switched back on (or to TracDSC for Dynamic mode).

The stability control uses different threshold values for the selected mode, reducing the requirement for the driver to change
the DSC system mode for optimum performance in various driving scenarios.
Incorrect Mode Usage

Selection of an inappropriate mode is discouraged in the following ways:

The active mode icon is continually displayed in the instrument cluster message center
In any special mode, when the ignition has been in the off position continuously for more than 6 hours, the JaguarDrive
Control system defaults to the special modes off (DSC on).

Selection of an inappropriate mode for the conditions will not endanger the driver or immediately cause damage to the vehicle.
Continued use of an inappropriate mode may reduce the life of some components. The driver may notice a different vehicle
response, with the engine and transmission responses being different than in the special modes off.
Driver Information

The instrument cluster contains a message center, which displays vehicle information to the driver. The message center
contains the JaguarDrive Control mode icons, which display the currently selected mode. If no symbol is displayed, no special
mode is selected and the system is in special modes off.

Any required changes to the subsystems are also passed to the driver in the form of warning illumination in the instrument
cluster or appropriate messages in the message center, DSC off for example.

In Dynamic mode when the transmission is in manual mode, the gear information is displayed in amber when the appropriate
engine speed is reached for optimum sporty change point.

DIAGNOSTICS

JaguarDrive Control relies on the correct functionality of the sub-systems. If one of the sub-systems develops a fault, the
JaguarDrive Control system will not function, even though the fault is not in the JaguarDrive Control system.

The JaguarDrive Selector module and rotary control should only be investigated if there are no apparent faults in any of the
sub-systems. If a fault in a sub-system is subsequently corrected, the JaguarDrive Control system will function normally after
an ignition on and off cycle.
