Always reduce the engine speed to idle before disconnecting the jump leads.
Before removing the jump leads, switch on the heater blower (high) or the heated rear screen, to reduce the voltage peak
when the leads are removed.
Always disconnect the jump leads in the reverse order to the connecting sequence and take great care not to short the ends of
the leads.
Do not rely on the generator to restore a discharged battery. For a generator to recharge a battery, it would take in excess of 8
hours continuous driving with no additional loads placed on the battery.
Component Cleaning
To prevent ingress of dirt, accumulations of loose dirt and greasy deposits should be removed before disconnecting or
dismantling components or assemblies.
Components should be thoroughly cleaned before inspection prior to reassembly.
Cleaning Methods:
Dry Cleaning
Removal of loose dirt with soft or wire brushes
Scraping dirt off with a piece of metal or wood
Wiping off with a rag
CAUTION: Compressed air is sometimes wet so use with caution, especially on hydraulic systems.
Blowing dirt off with compressed air (Eye protection should be worn when using this method)
Removal of dry dust using vacuum equipment. This method should always be used to remove friction lining material
dust (asbestos particles)
Steam Cleaning
Calibration of Essential Measuring Equipment
WARNING: Failure to comply may result in personal injury or damage to components.
It is of fundamental importance that certain essential equipment e.g. torque wrenches, multimeters, exhaust gas analysers,
rolling roads etc., are regularly calibrated in accordance with the manufacturers instructions.
Use of Control Modules
Control modules may only be used on the vehicle to which they were originally installed. Do not attempt to use or test a
control module on any other vehicle.
Functional Test
On completion of a maintenance procedure, a thorough test should be carried out, to ensure the relevant vehicle systems are
working correctly.
Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oil ways, exposed
by component removal, with tapered hardwood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a separate container for each component and its associated parts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the materials
within the component. Clean the bench and obtain marking materials, labels, containers and locking wire before dismantling a
component.
Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic systems
are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems.
Clean all tapped holes, crevices, oil ways and fluid passages with compressed air.
WARNING: Do not permit compressed air to enter an open wound. Always use eye protection when using compressed air.
Make sure that any O-rings used for sealing are correctly reinstalled or renewed if disturbed. Mark mating parts to make sure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of causing
distortion or the initiation of cracks, which could occur if a center punch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed for reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not discard a part which is due for renewal until it has been compared with the new part, to make sure

Noise, Vibration and Harshness - Noise, Vibration and Harshness (NVH)
Diagnosis and Testing
Principle of Operation
For a detailed description of Noise, Vibration and Harshness issues, refer to the Description and Operation section of the
workshop manual.
REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Description and Operation).
Inspection and Verification
1. Verify the customer's concerns by operating the vehicle to duplicate the condition.
2. Visually inspect the vehicle to determine any obvious cause(s) of the concern(s).
3. If the inspection reveals obvious causes that can be readily identified, repair as necessary.
4. If the concern(s) remains after the inspection, determine the symptom(s) and refer to the Symptom Chart.
How To Use This Diagnostic Procedure Section
Noise, vibration and harshness (NVH) concerns have become more important as vehicles have become more sensitive to
these vibrations. This section is designed as an aid to identifying these situations
The section provides diagnostic procedures based on symptoms. If the condition occurs at high speed, for instance, the
most likely place to start is under High Speed Shake
The road test procedure will tell how to sort the conditions into categories and how to tell a vibration from a shake
A series of Road Test Quick Checks is provided to make sure that a cause is either pinpointed or eliminated
Name the condition, proceed to the appropriate section and locate the correct diagnosis. When the condition is
identified, the job is partly done
Follow the diagnostic procedure as outlined
Quick Checks are described within the step, while more involved tests and adjustments are outlined in General
Procedures
Always follow each step exactly and make notes to recall important findings later
Customer Interview
The road test and customer interview (if available) provide information that will help identify the concerns and will provide
direction to the correct starting point for diagnosis.
Identify the Condition
NVH problems usually occur in a number of areas:
tires
engine accessories
suspension
driveline
air leakage (wind noise)
squeaks and rattles
heating ventilation and air conditioning (HVAC)
electrical (e.g. motor noise)
transmission
engine
It is important, therefore, that an NVH concern be isolated into its specific area(s) as soon as possible. The easiest and
quickest way to do this is to carry out the Road Test as outlined.
Noise Diagnostic Procedure
Non-Axle Noise
The five most important sources of non-axle noise are exhaust, tires, roof racks, trim and mouldings, and transmission.
Therefore, make sure that none of the following conditions are the cause of the noise before proceeding with a driveline tear
down and diagnosis.
Under certain conditions, the pitch of the exhaust may sound very much like gear noise. At other times, it can be
mistaken for a wheel bearing rumble
Tires, especially snow tires, can have a high pitched tread whine or roar, similar to gear noise. Radial tires, to some
degree, have this characteristic. Also, any non-standard tire with an unusual tread construction may emit a roar or
whine type noise
Trim and mouldings can also cause whistling or a whining noise
Clunk may be a metallic noise heard when the automatic transmission is engaged in reverse or drive, or it may occur
when the throttle is applied or released. It is caused by backlash somewhere in the driveline
Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a damaged wheel bearing

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.
Switching between DSC and Trac DSC:

Roof opening panel System Operation
Operation of the roof opening panel is controlled by the roof opening panel control module, which is integral with the motor.
The control module receives inputs from the CJB, which provides an 'open' or 'close' signal for remote handset operation, and
an 'enable' signal when the vehicle enters power mode 6.
The control module also receives a vehicle speed signal from the ABS module. The vehicle speed signal is used by the control
module to calibrate the anti-trap feature.
If the battery is disconnected, or the power supply is interrupted while the roof opening panel is in a partially open position,
the motor and control module will need to be calibrated to restore full functionality. To recalibrate:
1. Switch ignition on.
2. Press the front of the switch, so the roof opening panel is the tilt position, and then release the switch.
3. Press the front of the switch and hold for thirty seconds.
4. After thirty seconds the roof opening panel will begin to move. Keep the front of the switch pressed until the roof
opening panel has fully opened and then closed.
5. Once the open/close cycle has completed and the roof opening panel has stopped moving, release the switch.
6. The roof opening panel can now be operated as normal.
Drain hoses are connected to the front and rear corners of the roof opening panel frame. The drain hoses are located inside of
the cabin on the 'A' and 'D' post pillars to allow water, which has collected in the frame, to escape. One-way valves fitted to
the end of each drain hose, prevent the ingress of dirt and moisture.
Rear window sunblind
The powered rear window sunblind is operated through a switch in the roof console. Power to the sunblind motor is provided by
a pair of relays located in the CJB when the vehicle enters power mode 4. The sunblind motor is located beneath the rear parcel
shelf and is supplied as a sealed unit with the sunblind mechanism.
If the battery is disconnected or a replacement sunblind is fitted, the motor will require re-calibrating. To re-calibrate the
motor the sunblind should be powered through two-full cycles of movement.
Roof opening panel, motor Component Description
The roof opening panel motor has a worm drive which drives a gear in the cast housing attached to the end of the motor. The
gear has a small pinion gear attached to the outer part of its spindle. The pinion engages with two cables to form a rack and
pinion drive. Rotation of the motor turns the pinion which in turn drives the cables in the required direction.
The two cables are attached either side of the pinion. One end of each cable is attached to the guide; the opposite end of
each cable is held in position on the pinion by a metal insert in the frame. The cables run in channels, in the panel frame to
the guides. As the panel is closed the cables are pushed through channels in the front of the frame. The displaced cable is
guided into a further two channels in the frame, which protect the cable and prevent it from snagging. The cables
manufactured from rigid spring steel can pull as well as push the panel along the guides.
The motor contains a micro-switch and Hall effect sensor. Signals received from these components enable the control module
to calculate the exact position of the roof opening panel. The Hall effect sensor is also responsible for the operation of the
anti-trap function.
If the anti-trap feature is activated while the roof opening panel is closing, the panel is reversed for 200mm or as far as
possible. The Hall effect sensor, located in the motor, monitors the speed of the motor and if the speed decreases below a set
threshold, indicating an obstruction, the power feed to the motor is reversed so the panel goes back. In an emergency the
anti-trap function can be overridden by holding the switch in the closed position.
Roof opening panel, control module
The roof opening panel control module is integrated within the motor. The control module receives inputs from the CJB, which
provides an 'open' or 'close' signal for remote handset operation, and an 'enable' signal when the vehicle enters power mode 6.
The control module also contains the algorithm for the anti-trap system and receives a vehicle speed signal from the ABS
module. The vehicle speed signal is used by the control module to calibrate the anti-trap feature.
