1. To install, reverse the removal procedure.


2. CAUTION: Make sure the wiring harness is correctly routed
to avoid contact with the halfshaft. Failure to follow this
instruction may result in damage to the component.












3. CAUTION: Calibrate the electric park brake using Jaguar approved
diagnostic system. If the Jaguar approved diagnostic system is not
available disconnect the battery for approximately 30 seconds, the

Anti-Lock Brake System System Operation

ABS controls the speed of all road wheels to ensure optimum wheel slip when braking at the adhesion limit. The wheels are prevented from locking to retain effective steering control of the vehicle.

The brake pressures are modulated separately for each wheel. Rear brake pressures are controlled to maintain rear stability on
split friction surfaces.

Dynamic Stability Control

DSC (dynamic stability control) uses brakes and powertrain torque control to assist in maintaining the yaw stability of the
vehicle. While the ignition is energized the DSC function is permanently enabled, unless selected off using the DSC switch.

DSC enhances driving safety in abrupt maneuvers and in under-steer or over-steer situations that may occur in a bend. The
ABS module monitors the yaw rate and lateral acceleration of the vehicle, steering input and individual wheel speeds, then selectively applies individual brakes and signals for powertrain torque adjustments to reduce under-steer or over-steer
conditions.
In general:

In an under-steer situation the inner wheels are braked to counteract the yaw movement towards the outer edge of the
bend.
In an over-steer situation the outer wheels are braked to prevent the rear end of the vehicle from pushing towards the
outer edge of the bend.

The ABS module monitors the tracking stability of the vehicle using inputs from the wheel speed sensors, the steering angle sensor, and the yaw rate and lateral acceleration sensor. The tracking stability is compared with stored target data. Whenever
the tracking stability deviates from the target data, the ABS module intervenes by applying the appropriate control strategy. The following interactions occur in an intervention situation:

High speed CAN signal to the ECM, to reduce engine torque. Application of braking to the appropriate corner of the vehicle.
Trac DSC

TracDSC is an alternative setting of DSC with reduced system interventions. With TracDSC engaged, traction may be somewhat
increased, although stability may be reduced compared to normal DSC. TracDSC is intended for use only on dry tarmac, by
suitably experienced drivers and should not be selected for other surfaces or by drivers with insufficient skill and training to
operate the vehicle safely with the TracDSC function engaged.

The less restrictive TracDSC setting may be preferred, for example, by expert drivers engaged in high performance driving on
dry Tarmac surfaces such as tracks and circuits.

Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol - Transmission Fluid Level Check
General Procedures





WARNINGS: Activation

Observe due care when draining, as the fluid can be very hot.
Observe due care when working near a hot exhaust system.
1.
The following steps must be observed before starting the
transmission fluid level check.
The vehicle must be on a horizontal ramp.
The parking brake must be applied.
The engine must be running for 2 minutes with the transmission
control switch (TCS) in the "P" position.


2. CAUTION: Make sure that the transmission fluid temperature is
below 30 degrees before starting the fluid level check.
Connect Jaguar approved diagnostic equipment to the vehicle.

3.
Apply, and hold, the footbrake.
Move the selector lever from 'P' through all the gear positions,
pausing in each gear position for 2-3 seconds and return to the
'P' position.


4. WARNING: Make sure to support the vehicle with axle stands.
Raise and support the vehicle.

5. Refer to: Air Deflector (501-02 Front End Body Panels, Removal and Installation).

6. Place a suitable container under the transmission fluid fill plug. 307-452
Wrench, Transmission Filler Plug Special Tool(s)

1 Latch 2 Strap 3 Locking cylinder 4 Operating lever 5 Upper cable 6 Cable joint 7 Lower cable 8 Cable bracket 9 Park interlock lever If a vehicle requires recovery/transportation, the emergency park release mechanism is used to manually disengage the park
lock and engage the transmission in neutral.

The emergency park release mechanism consists of an operating lever that is connected to a park interlock lever on the
transmission by an upper and lower cable assembly.

The operating lever is installed in the floor console, under the trim panel between the drinks holder and the cubby box. The
park interlock lever is attached to the transmission selector shaft.

One end of the operating lever is attached to a base by a hinge pin. A locking cylinder is installed in the other end of the
operating lever, to secure the operating lever to the base. The operating lever is raised by pulling on a strap.
When operated, the emergency park release mechanism turns the transmission selector shaft.
To disengage the park lock:
Open the cubby box lid and the drinks holder lid.
Remove the trim panel from between the drinks holder and the cubby box.
Rotate the locking mechanism of the emergency park release lever 90 degrees counterclockwise.
Apply the footbrake, pull the operating lever upwards and ensure it locks in the vertical position.

Raising the operating lever causes the emergency park release cable to rotate the park interlock lever on the transmission,
which disengages the parking pawl and engages neutral. This allows the vehicle to freewheel.
To re-engage the park lock:

Hold the strap on the operating lever, release the latch and lower the operating lever to the horizontal position.
Lock the operating lever by turning the locking mechanism 90 degrees clockwise.
Install the trim panel.
Close the cubby box lid and the drinks holder lid. www.JagDocs.com
