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

Have a suitable fire extinguisher available when using welding or heating equipment.

First Aid

Apart from meeting any legal requirements it is desirable for someone in the workshop to be trained in First Aid procedures.
Splashes in the eye should be flushed carefully with clean water for at least ten minutes.
Soiled skin should be washed with soap and water.

Individuals affected by inhalation of gases, fumes etc. should be removed to fresh air immediately. If effects persist, consult a
doctor.

If liquids are swallowed inadvertently, consult a doctor giving the information on the container or label. Do not induce vomiting
unless this action is indicated on the label.

Fluoroelastomer

See Viton.

Foams - Polyurethane

See also Fire.
Used in sound and noise insulation. Cured foams used in seat and trim cushioning.
Follow manufacturer's instructions.
Unreacted components are irritating and may be harmful to the skin and eyes. Wear gloves and goggles.

Individuals with chronic respiratory diseases, asthma, bronchial medical problems, or histories of allergic diseases should not
work in or near uncured materials.
The components, vapors or spray mists can cause direct irritation, sensitivity reactions and may be toxic or harmful.

Vapors and spray mists must not be inhaled. These materials must be applied with adequate ventilation and respiratory
protection. Do not remove the respirator immediately after spraying, wait until the vapor/mists have cleared.

Burning of the uncured components and the cured foams can generate toxic and harmful fumes. Smoking, naked flames or the
use of electrical equipment during foaming operations and until vapors/mists have cleared should not be allowed. Any heat
cutting of cured foams or partially cured foams should be conducted with extraction ventilation.

Freon

See Air Conditioning Refrigerant.

Fuels

See also, Fire, Legal Aspects, Chemicals and Solvents.
Avoid skin contact with fuel where possible. Should contact occur, wash the affected skin with soap and water.

Gasoline (Petrol)

Highly flammable - observe No Smoking policy.

Swallowing can result in mouth and throat irritation and absorption from the stomach can result in drowsiness and
unconsciousness. Small amounts can be fatal to children. Aspiration of liquid into the lungs e.g. through vomiting, is a very
serious hazard.

Gasoline dries the skin and can cause irritation and dermatitis on prolonged or repeated contact. Liquid in the eye causes
severe pain.

Motor gasoline may contain appreciable quantities of benzene, which is toxic upon inhalation, and the concentration of
gasoline vapors must be kept very low. High concentrations will cause eye, nose and throat irritation, nausea, headache,
depression and symptoms of drunkenness. Very high concentrations will result in rapid loss of consciousness.

Ensure there is adequate ventilation when handling and using gasoline. Great care must be taken to avoid the serious
consequences of inhalation in the event of vapor build up arising from spillages in confined spaces.
Special precautions apply to cleaning and maintenance operations on gasoline storage tanks.
Gasoline should not be used as a cleaning agent. It must not be siphoned by mouth. See First Aid.
Gas - oil (Diesel Fuel)
See warnings and cautions in relevant manual sections.

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

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

With the control valve (7) OPEN and the engine idling, the following system pressures may be checked:

During turning when static (dry parking pressure).
When the steering is held on full lock (maximum system pressure or pressure relief).
With the steering at rest (idle pressure or back pressure).
CAUTIONS:


To avoid excessive heating of the power steering pump when checking the pressure, do not close the valve for more than
5 seconds maximum.


When checking the pump pressure DO NOT drive the vehicle with the test equipment installed.

With the control valve (7) CLOSED the power steering pump maximum output pressure can be checked.

Removing Test Equipment

To remove the test equipment:

Install a hose clamp on the reservoir to power steering pump hose.
Removing the test equipment is a reversal of the installation instructions.
Install a new 'O' ring seal (9) to the power steering pump high pressure outlet to hose connection.
Install the original hose to the power steering pump.
Remove the clamp from the reservoir to the power steering pump hose.
Top-up the reservoir fluid.
Bleed the power steering system.
REFER to: Power Steering System Bleeding (211-00 Steering System - General Information, General Procedures).
Description of Terms General Steering System Noises
Boom
Rhythmic sound like a drum roll or distant thunder. May cause pressure on the ear drum.

Buzz

Low-pitched sound, like a bee. Usually associated with vibrations.

Chatter

Rapidly repeating metallic sound.

Chuckle

Rapid noise that sounds like a stick against the spokes of a spinning bicycle wheel.

Chirp

High pitched rapidly repeating sound, like chirping birds.

Click

Light sound, like a ball point pen being clicked.

Click/Thump

Heavy metal-to-metal sound, like a hammer striking steel.

Grind

Abrasive sound, like a grinding wheel or sandpaper rubbing against wood.

Groan/Moan

Continuous, low-pitched humming sound.

Groan/Howl

Low, guttural sound, like an angry dog.

Hiss

Continuous sound like air escaping from a tire valve.
