disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc
player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the
battery in the event of a short circuit.

Reconnecting the Battery


WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating
sparks, and if in doubt cover the vent plugs or covers with a damp cloth.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or
damage to sensitive electrical equipment.

Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the
battery terminals are secure.
Restart the clock (where installed) and set it to the correct time.
Enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.

Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature
as the stored idle and drive values contained within the ECM have been lost. Allow the vehicle to idle for a further three
minutes. Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96
km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This will allow the ECM to relearn idle and drive values, and
may cause driveability concerns if the procedure is not carried out.

Connecting a Slave Battery Using Jump Leads


WARNING: If the slave battery has recently been charged and is gassing, cover the vent plugs or covers with a damp
cloth to reduce the risk of explosion should arcing occur when connecting the jump leads.
CAUTIONS:


A discharged battery condition may have been caused by an electrical short circuit. If this condition exists there will be
an apparently live circuit on the vehicle even when all circuits are switched off. This can cause arcing when the jump leads are
connected.


Whilst it is not recommended that the vehicle is jump started, it is recognized that this may occasionally be the only
practical way to mobilize a vehicle. In such an instance the discharged battery must be recharged immediately after jump
starting to avoid permanent damage.
Always make sure that the jump leads are adequate for the task. Heavy duty cables must be used.
Always make sure that the slave battery is of the same voltage as the vehicle battery. The batteries must be connected
in parallel.
Always make sure that switchable electric circuits are switched off before connecting jump leads. This reduces the risk
of sparks occurring when the final connection is made.




WARNING: Make sure that the ends of the jump leads do not touch each other or ground against the vehicle body at any
time while the leads are attached to the battery. A fully charged battery, if shorted through jump leads, can discharge at a rate
well above 1000 amps causing violent arcing and very rapid heating of the jump leads and terminals, and can even cause the
battery to explode.
Always connect the jump leads in the following sequence.
Slave battery positive first then vehicle battery positive.
Slave battery negative next and then vehicle ground at least, 300 mm (12 in) from the battery terminal e.g. engine
lifting bracket. www.JagDocs.com

General Information - Road/Roller Testing
Description and Operation Published: 11-May-2011

Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section.

Unless complete vehicle performance is being checked, the full road test procedure need not be carried out. Instead, those
items particularly relevant to the system/s being checked can be extracted.

Pre - Test Checks


WARNING: If the brake system hydraulic fluid level is low, pedal travel is excessive or a hydraulic leak is found, do not
attempt to road test the vehicle until the reason for the low fluid level, excessive pedal travel or hydraulic leak is found and
rectified.

It is suggested that pre-test checks, and functional tests of those systems/circuits which affect the safe and legal operations
of the vehicle, such as brakes, lights and steering, should always be carried out before the road or roller test.

Engine oil level
Engine coolant level
Tires, for correct pressure, compatible types and tread patterns, and wear within limits
There is sufficient fuel in the tank to complete the test
All around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any
apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of
the test
Starting the Engine


CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). Never operate at high engine speed or
with the accelerator pedal at full travel whilst the engine is cold.
With the ignition switched off, check:
The parking brake is applied
The transmission selector lever is in Park
All instrument gauges (except fuel gauge) read zero

With the ignition switched on, check:

Ignition controlled warning lamps come on
Engine coolant temperature gauge registers a reading compatible with the engine coolant temperature
Fuel gauge registers a reading appropriate to the fuel level in the tank
The operation of the parking brake and brake fluid level warning lamps

On Road or Roller Test Check:


CAUTION: If road testing, check the brake operation while still travelling at low speed before continuing with the test. If
the brakes pull to one side, or appear to be otherwise faulty, do not continue with the road test until the fault has been found
and rectified.
Initial gear engagement is smooth
Parking brake control operates smoothly and the parking brake releases quickly and completely
Transmission takes up the drive smoothly, without judder
The engine power output is satisfactory, full power is achieved, acceleration is smooth and pedal operation not stiff or
heavy, and engine speed returns to idle correctly
There is no excessive or abnormally colored smoke from the engine under normal driving, heavy load or overrun
conditions
Steering operation, including power steering, is smooth, accurate, not excessively heavy or with excessive free play or
vibration. Does not pull to one side and self centres smoothly after cornering
Speedometer, oil pressure warning lamp, coolant temperature gauge and tachometer register the correct readings or
operate correctly
Switches and controls operate smoothly and positively, warning lamps operate correctly and the direction indicator
control self cancels when the steering is returned to the straight ahead position
Heating and ventilation systems work correctly and effectively
Brake operation and efficiency

Brake Testing


WARNING: When brake testing, avoid breathing the smoke or fumes from hot brakes, this may contain asbestos dust
which is hazardous to health, see Health and Safety Precautions.

it may turn out to be the most important.

2. Do not touch anything until a road test and a thorough visual inspection of the vehicle have been carried out. Leave the
tire pressures and vehicle load just where they were when the condition was first observed. Adjusting tire pressures,
vehicle load or making other adjustments may reduce the conditions intensity to a point where it cannot be identified
clearly. It may also inject something new into the system, preventing correct diagnosis.

3. Make a visual inspection as part of the preliminary diagnosis routine, writing down anything that does not look right.
Note tire pressures, but do not adjust them yet. Note leaking fluids, loose nuts and bolts, or bright spots where
components may be rubbing against each other. Check the luggage compartment for unusual loads.
4. Road test the vehicle and define the condition by reproducing it several times during the road test.

5. Carry out the Road Test Quick Checks as soon as the condition is reproduced. This will identify the correct diagnostic
procedure. Carry out the Road Test Quick Checks more than once to verify they are providing a valid result. Remember,
the Road Test Quick Checks may not tell where the concern is, but they will tell where it is not.

Road Test Quick Checks

1. 24-80 km/h (15-50 miles/h): With light acceleration, a moaning noise is heard and possibly a vibration is felt in the
front floor pan. It is usually worse at a particular engine speed and at a particular throttle setting during acceleration at
that speed. It may also produce a moaning sound, depending on what component is causing it. Refer to Tip-In Moan in
the Symptom Chart.

2. Acceleration/deceleration: With slow acceleration and deceleration, a shake is sometimes noticed in the steering
wheel/column, seats, front floor pan, front door trim panel or front end sheet metal. It is a low frequency vibration
(around 9-15 cycles per second). It may or may not be increased by applying brakes lightly. Refer to Idle Boom/Shake
/Vibration in the Symptom Chart.

3. High speed: A vibration is felt in the front floor pan or seats with no visible shake, but with an accompanying sound or
rumble, buzz, hum, drone or booming noise. Coast with the clutch pedal depressed or shift control selector lever in
neutral and engine idling. If vibration is still evident, it may be related to wheels, tires, front brake discs, wheel hubs
or front wheel bearings. Refer to High Speed Shake in the Symptom Chart.

4. Engine rpm sensitive: A vibration is felt whenever the engine reaches a particular rpm. It will disappear in neutral
coasts. The vibration can be duplicated by operating the engine at the problem rpm while the vehicle is stationary. It
can be caused by any component, from the accessory drive belt to the torque converter which turns at engine speed
when the vehicle is stopped. Refer to High Speed Shake in the Symptom Chart.

5. Noise/vibration while turning: Clicking, popping, or grinding noises may be due to a worn, damaged, or incorrectly
installed front wheel bearing, rear drive half shaft or CV joint.

6. Noise/vibration that is road speed relative: This noise/vibration can be diagnosed independent of engine speed or gear
selected (engine speed varies but torque and road speed remain constant). The cause may be a rear drive
axle/differential whine.
Road Conditions

An experienced technician will always establish a route that will be used for all NVH diagnosis road tests. The road selected
should be reasonably smooth, level and free of undulations (unless a particular condition needs to be identified). A smooth
asphalt road that allows driving over a range of speeds is best. Gravel or bumpy roads are unsuitable because of the additional
road noise produced. Once the route is established and consistently used, the road noise variable is eliminated from the test
results.


NOTE: Some concerns may be apparent only on smooth asphalt roads.

If a customer complains of a noise or vibration on a particular road and only on a particular road, the source of the concern
may be the road surface. If possible, try to test the vehicle on the same type of road.

Vehicle Preparation

Carry out a thorough visual inspection of the vehicle before carrying out the road test. Note anything which is unusual. Do not
repair or adjust any condition until the road test is carried out, unless the vehicle is inoperative or the condition could pose a
hazard to the technician.
After verifying the condition has been corrected, make sure all components removed have been installed.

Lift Test

After a road test, it is sometimes useful to do a similar test on a lift.

When carrying out the high-speed shake diagnosis or engine accessory vibration diagnosis on a lift, observe the following
precautions:


WARNING: If only one drive wheel is allowed to rotate, speed must be limited to 55 km/h (35 miles/h) indicated on the
speedometer since actual wheel speed will be twice that indicated on the speedometer. Speed exceeding 55 km/h (35 miles/h)
or allowing the drive wheel to hang unsupported could result in tire disintegration, differential failure, constant velocity joint

Upper Control Arm
The forged-aluminum upper control arm is a wishbone design and connects to the vehicle body through two plain bushes, and
links to the swan neck wheel knuckle by an integral ball joint. The upper control arm is inclined to provide anti-dive
characteristics under heavy braking, while also controlling geometry for vehicle straight-line stability.

Lower Control Arm

The forged aluminum lower control arms are of the wishbone design; the arms separate to allow for optimum bush tuning:

The rear lateral control arm is fitted with a bush at its inner end which locates between brackets on the subframe. The
arm is secured with an eccentric bolt which provides the adjustment of the suspension camber geometry. The outer end
of the control arm has a tapered hole which locates on a ball joint fitted to the wheel knuckle. An integral clevis bracket
on the forward face of the lateral control arm allows for the attachment of the forward control arm. A bush is fitted
below the clevis bracket to provide for the attachment of the stabilizer bar link. A cross-axis joint is fitted to a
cross-hole in the control arm to provide the location for the clevis attachment of the spring and damper assembly.
The forward control arm is fitted with a fluid-block rubber bush at its inner end which locates between brackets on the
subframe. The arm is secured with an eccentric bolt which provides adjustment of the castor and camber geometry. The
outer end of the control arm is fitted with a cross-axis joint and locates in the integral clevis bracket on the lateral
control arm.

Wheel Knuckle

The cast aluminum wheel knuckle is a swan neck design and attaches to the upper control arm and lower lateral control arm.
The lower lateral control arm locates on a non serviceable ball-joint integral with the wheel knuckle. The lower boss on the
rear of the knuckle provides for the attachment of the steering gear tie-rod ball joint.
The wheel knuckle also provides the mounting locations for the:
wheel hub and bearing assembly
the wheel speed sensor (integral to the wheel hub and bearing assembly)
brake caliper and disc shield.

Stabilizer Bar

The stabilizer bar is attached to the front of the subframe with bushes and mounting brackets. The pressed steel mounting
brackets locate over the bushes and are attached to the cross member with bolts screwed into threaded locations in the
subframe. The stabilizer bar has crimped, 'anti-shuffle' collars pressed in position on the inside edges of the bushes. The
collars prevent sideways movement of the stabilizer bar.

The stabilizer bar is manufactured from 32mm diameter tubular steel on supercharged models and 31mm diameter tubular
steel on diesel and normally aspirated models and has been designed to provide particular characteristics in maintaining roll
rates, specifically in primary ride comfort.

Each end of the stabilizer bar curves rearwards to attach to a ball joint on a stabilizer link. Each stabilizer link is secured to a
bush in the lower lateral arm with a bolt and locknut. The links allow the stabilizer bar to move with the wheel travel providing
maximum effectiveness.

The only difference between the front stabilizer bars, in addition to the diameter, is in the shape to accommodate engine
variant:

a slightly curved bar, between bush centers, for V6 diesel (31 mm dia) and V8 gasoline supercharged (32 mm dia),
a straight bar, between bush centers, for V6 and V8 normally aspirated gasoline engines (31 mm dia).
Spring and Damper Assembly

The spring and damper assemblies are located between the lower lateral arm and the front suspension housing in the inner
wing. Dependant on vehicle model there are three types of coil spring and damper available:
a standard oil passive damper (All models except supercharged),
an adaptive damper, also known as Computer Active Technology Suspension (CATS) on 4.2L supercharged vehicles up to
2010MY, For additional information refer to Vehicle Dynamic Suspension 4.2L.
a continuously variable adaptive damper, also known as Adaptive Dynamics System on 5.0L supercharged vehicles from
2010MY. For additional information refer to Vehicle Dynamic Suspension 5.0L.

The dampers are a monotube design with a spring seat secured by a circlip onto the damper tube. The damper's lower
spherical joint is an integral part of the lateral lower control-arm, and the damper takes the form of a clevis-end, which
straddles the spherical joint.

The damper piston is connected to a damper rod which is sealed at its exit point from the damper body. The threaded outer
end of the damper rod locates through a hole in the top mount. A self locking nut secures the top mount to the damper rod.
The damper rod on the adaptive damper has an electrical connector on the outer end of the damper rod.

Supercharged 4.2L vehicles up to 2010MY: The adaptive damper functions by restricting the flow of hydraulic fluid through
internal galleries in the damper's piston. The adaptive damper has a solenoid operated valve, which when switched allows a
greater flow of hydraulic fluid through the damper's piston. This provides a softer damping characteristic from the damper. The
adaptive damper defaults to a firmer setting when not activated. The solenoid is computer controlled and can switch between
soft and hard damping settings depending on road wheel inputs and vehicle speed.

Supercharged 5.0L vehicles from 2010MY: The variable damper functions by adjustment of a solenoid operated variable orifice,
which opens up an alternative path for oil flow within the damper. When de-energized the bypass is closed and all the oil flows

Wheels and Tires - Wheels and Tires - Overview
Description and Operation

OVERVIEW Published: 25-May-2012

A number of alloy wheel designs are available ranging from 17 to 20 inch in diameter. A Tire Pressure Monitoring System
(TPMS) is used to monitor the air pressure in each tire and inform the driver if the pressure falls below predetermined
thresholds.

All wheels are of cast construction in aluminum alloy with the choice of wheel design dependant on the vehicle trim level and
engine derivative.

On normally aspirated petrol models and all diesel models a 4J X 18 inch temporary spare wheel is supplied as standard,
supercharged petrol models are supplied with a 4Jx19 inch temporary spare wheel. In some major European markets an Instant
Mobility System is offered as an alternative to the spare wheel. The Instant Mobility System is capable of providing a
temporary repair and tire inflation to a puncture of up to 6mm in diameter in the tread area of the tire. A puncture in the tire
wall cannot be repaired using the system.
The vehicle jack and accessories are stored in the spare wheel-well in the luggage compartment.

Tire Changing

WARNINGS:


Tires must be inflated to the recommended pressures when the tires are cold (ambient temperature) only. Refer to label
on the 'B' pillar for recommended tire pressures. If the tires have been subjected to use or exposed to direct sunlight, move
the vehicle into a shaded position and allow the tires to cool before checking or adjusting the pressures.


Valve stem seal, washer nut, valve core and cap should be replaced at every tire change. Valve stem seal, washer and
nut must be replaced if the valve retention nut is loosened. Sensor units and nuts must be fitted using correct torque figures
and associated profile. Damage to the vehicle and consequently injury to the vehicle's occupants may result if these
instructions are not adhered to.


NOTE: The TPMS valve should be serviced using the suitable service kit, each time the tyre is dismounted, to ensure an
air tight seal. Attention should be made to the detail of fitting this kit.

Vehicles fitted with TPMS can be visually identified by an external metal locknut and valve of the tire pressure sensor on the
road wheels. Vehicles without TPMS will have rubber tire valve.

Clunk

Clunk is a metallic noise heard when the automatic transmission is engaged in REVERSE or DRIVE. The noise may also occur
when the throttle is applied or released. Clunk is caused by transmission calibration, backlash in the driveline or loose
suspension components and is felt or heard in the vicinity of the rear drive axle.

Bearing Rumble

Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a worn/damaged wheel bearing. The
lower pitch is because the wheel bearing turns at only about one-third of the driveshaft speed. Wheel bearing noise also may
be high-pitched, similar to gear noise, but will be evident in all four driving modes.

Driveshaft System Operation

The two-piece driveshaft, manufactured from lightweight tubular steel, transmits drive from the engine, via the transmission,
to the differential. The driveshaft aligns with the centerline of the vehicle’s body and is supported by a center bearing.

The driveshaft's front tube is of swaged construction, which is a crash energy management feature, designed to collapse
progressively and predictably in the event of a severe frontal impact. A low-friction splined slip-joint at the center of the
driveshaft provide the driveshaft's plunge capability.

Flexible couplings connecting the driveshaft to both the transmission and the differential counteract the angular movement of
the driveshaft caused by the driveline's acceleration and braking forces.

The center universal joint is positioned at a specified angle using shims between the center bearing and the vehicle's body.
The driveline angles have been carefully configured to balance minimum power losses with excellent vibration and wear
characteristics. The universal joint is lubricated during manufacture and sealed for life.
