General Information - Health and Safety Precautions
Description and Operation Published: 11-May-2011
The Health and Safety Precautions subsection refers to some commonly used chemicals and materials, hazards associated with
their use, and safety measures to be taken. Some of these chemicals may be included in the following list either in their own
right or as an ingredient in a sealer or adhesive.
Acids and Alkalis
See also Battery Acids.
e.g. caustic soda, sulphuric acid.
Used in batteries and cleaning materials.
Irritant and corrosive to the skin, eyes, nose and throat. Cause burns. Can destroy ordinary protective clothing.
Avoid splashes to the skin, eyes and clothing. Wear suitable protective impervious apron, gloves and goggles. Do not breath
mists.
Ensure access to eye wash bottles, shower and soap are readily available for splashing accidents.
Display Eye Hazard sign.
Air Bags
See also Fire, Chemical Materials - General
Highly flammable, explosive – observe No Smoking policy.
Used as a part of the Supplemental Restraint System (SRS), mounted in various positions around the vehicle.
The inflator contains a high-energetic propellant which, when ignited, produces a VERY HOT GAS (2500° C).
The gas generant used in air bags is Sodium Azide. This material is hermetically sealed in the module and is completely
consumed during deployment. No attempt should be made to open an air bag inflator as this will lead to the risk of exposure
to Sodium Azide. If a gas generator is ruptured, full protective clothing should be worn when dealing with the spillage.
After normal deployment, gloves and safety goggles should be worn during the handling process.
Deployed air bags should be disposed of in a plastic bag in accordance with local regulations at an approved chemical waste
site.
Following any direct contact with gas generant.
Wash affected areas thoroughly with water
Seek medical assistance if necessary
WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted
before repairing or replacing any SRS components. To deplete the backup power supply energy, disconnect the battery negative
cable and wait for one minute. Failure to follow this instruction may result in personal injury.
NOTE: The storage, transportation, disposal and/or recycling of air bag modules must be carried out in accordance with all
applicable federal, state and local regulations including, but not limited to, those governing building and fire codes,
environmental protection, occupational health and safety and transportation.
Air Bags - Do's
Do store in an air bag safe when not installed to the vehicle.
Do store modules in an upright position
Do keep modules dry
Do carry modules with the cover side pointing away from the body
Do place modules with their cover side upwards
Do carefully inspect modules for damage
Do stand to one side when connecting modules
Do make sure all test equipment is properly calibrated and maintained
Do wash you hands after handling deployed air bags
Do wear safety glasses when carrying out repairs to the SRS or when handling an air bag module
Only carry out a system test with the air bag modules fully installed
Do inspect the condition of the impact sensor mounting bracket and sensor flylead if the vehicle has been involved in
an impact. Replace if damaged, even if there has been no deployment.
Air Bags - Do Nots
Do not store highly flammable material together with modules or gas generators
Do not store gas generators at temperatures exceeding 80° C
Viton
In common with many other manufacturers' vehicles, some components installed to the Jaguar range have 'O' rings, seals or
gaskets which contain a material known as 'Viton'.
Viton is a fluoroelastomer, that is a synthetic rubber type which contains Fluorine. It is commonly used for 'O' rings, gaskets
and seals of all types. Although Viton is the most well known fluoroelastomer, there are others, including Fluorel and
Tecmoflon.
When used under design conditions fluoroelastomers are perfectly safe. If, however, they are exposed to temperatures in
excess of 400º C, the material will not burn, but will decompose, and one of the products formed is hydrofluoric acid.
This acid is extremely corrosive and may be absorbed directly, through contact, into the body.
'O' rings, seals or gaskets which have been exposed to very high temperatures will appear charred or as a black sticky
substance.
DO NOT, under any circumstances touch them or the attached components.
Enquiries should be made to determine whether Viton or any other fluoroelastomer has been used in the affected 'O' ring, seal
or gasket. If they are of natural rubber or nitrile there is no hazard. If in doubt, be cautious and assume that the material may
be Viton or any fluoroelastomer.
If Viton or any other fluoroelastomers have been used, the affected area should be decontaminated before the commencement
of work.
Disposable heavy duty plastic gloves should be worn at all times, and the affected area washed down using wire wool and a
limewater (calcium hydroxide) solution to neutralize the acid before disposing of the decomposed Viton residue and final
cleaning of the area. After use, the plastic gloves should be discarded carefully and safely.
Welding
See also Fire, Electric Shock, Gas Cylinders.
Welding processes include Resistance Welding (Spot Welding), Arc Welding and Gas Welding (and cutting).
Resistance Welding (Spot Welding)
This process may cause particles of molten metal to be emitted at a high velocity, and the eyes and skin must be protected.
Arc Welding
This process emits a high level of ultraviolet radiation which may cause arc-eye and skin burns to the operator and to other
persons nearby. Gas-shielded welding processes are particularly hazardous in this respect. Personal protection must be worn,
and screens used to shield other people.
CONTACT LENS WEARERS ARE ADVISED TO REVERT TO ORDINARY SPECTACLES WHEN ARC WELDING as the arc spectrum is
believed to emit microwaves which dry out the fluid between the lens and the eye. This may result in blindness when the lens
is removed from the eye.
Metal spatter will also occur, and appropriate eye and skin protection is necessary.
The heat of the welding arc will produce fumes and gases from the metals being welded, the rods and from any applied
coatings or contamination on the surfaces being worked on. These gases and fumes may be toxic and inhalation of these
should be avoided. The use of extraction ventilation to remove the fumes from the working area may be necessary particularly
in cases where the general ventilation is poor, or where considerable welding work is anticipated. In extreme cases or confined
spaces where adequate ventilation cannot be provided, air-fed respirators may be necessary.
Gas Welding (and Cutting)
Oxy-acetylene torches may be used for welding and cutting, and special care must be taken to prevent leakage of these gases,
with consequent risk of fire and explosion.
The process will produce metal spatter and eye and skin protection is necessary.
The flame is bright, and eye protection should be used, but the ultraviolet emission is much less than that from arc welding,
and lighter filters may be used.
The process itself produces few toxic fumes, but such fumes and gases may be produced from coatings on the work,
particularly during cutting away of damaged body parts, and inhalation of the fumes should be avoided.
In brazing, toxic fumes may be produced from the metals in the brazing rod, and a severe hazard may arise if brazing rods
containing cadmium are used. In this event particular care must be taken to avoid inhalation of fumes and expert advice may
be required.
SPECIAL PRECAUTIONS MUST BE TAKEN BEFORE ANY WELDING OR CUTTING TAKES PLACE ON VESSELS WHICH HAVE
CONTAINED COMBUSTIBLE MATERIALS, E.G. BOILING OR STEAMING OUT OF FUEL TANKS.
Warning Symbols on Vehicles
Decals showing warning symbols will be found on various vehicle components.
Supplementary Restraint System (SRS) Precautions
WARNING: Do not install rear facing child seats in the front passenger seat.
The SRS contains components which are potentially hazardous to service personnel if not handled correctly. The following
guidelines and precautions are intended to alert personnel to potential sources of danger and emphasise the importance of
ensuring the integrity of the SRS components installed to the vehicle.
WARNING: The following precautions MUST be adhered to when working on the SRS system:
The correct procedures must always be used when working on SRS components.
Persons working on the SRS system must be fully trained and have been issued with the safety guidelines.
The airbag modules contain extremely flammable and hazardous compounds. Contact with water, acids or heavy
metals may produce harmful or explosive results. Do not dismantle, incinerate or bring into contact with electricity
before the unit has been deployed.
Always replace a seat belt assembly that has withstood the strain of a severe vehicle impact or if the webbing
shows signs of fraying.
Always disconnect the vehicle battery before carrying out any electric welding on a vehicle installed with an SRS
system.
CAUTION: Do not expose airbag modules or seat belt pre-tensioners to temperatures exceeding 85° C (185° F).
It should be noted that these precautions are not restricted to operations performed when servicing the SRS system. The same
care should be exercised when working on ancillary systems and components located in the vicinity of SRS components; these
include but are not limited to:
Steering wheel airbag, rotary coupler.
Passenger front airbag.
Head airbag modules - front and rear.
Seat belt pre-tensioners.
SRS harnesses, link leads and connectors.
Side (thorax) air bags.
Making the system safe
Before working on or in the vicinity of SRS components, make sure the system is rendered safe by performing the following
operations:
Remove the ignition key.
Disconnect battery, earth lead first.
Wait 2 minutes for the SRS power circuit to discharge before commencing work.
NOTE: The SRS uses energy reserve capacitors to keep the system active in the event of electrical supply failure under
crash conditions. It is necessary to allow the capacitors sufficient time to discharge (2 minutes) in order to avoid the risk of
accidental deployment.
Installation
In order to make sure system integrity, it is essential that the SRS system is regularly checked and maintained so that it is
ready for effective operation in the event of a collision. Carefully inspect SRS components before installation. Do not install a
part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
WARNING: The integrity of the SRS systems is critical for safety reasons. Make sure the following precautions are always
adhered to:
Do not install accessories or other objects to trim panels which cover ITS airbags.
Never install used SRS components from another vehicle or attempt to repair an SRS component.
When repairing an SRS system, only use genuine new parts.
Never apply electrical power to an SRS component unless instructed to do so as part of an approved test
procedure.
Special fixings are necessary for installing an airbag module – do not use other fixings and make sure that all
fixings are tightened to the correct torque.
Always use new fixings when replacing an SRS component.
CAUTIONS:
Take care not to trap airbag modules when installing interior trim components.
Make sure SRS components are not contaminated by oil or grease.
NOTES:
Following seat belt pre-tensioner deployment, the seat belts can still be used as conventional seat belts but will need to

Live air bag modules must be placed in a suitable cage when removed from the vehicle. The air bag or trim cover must be
facing upwards.
Do not install a rearward facing child safety seat to the passenger seat with an activated passenger air bag.
CAUTIONS:
Pyrotechnic components must not be subjected to temperatures higher than 110°C.
Never install aftermarket accessories to the vehicle on or adjacent to the supplemental restraint system module.
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.
Avoid brake testing on busy roads where it can cause inconvenience or danger to other road users.
CAUTION: Brake testing which includes heavy brake applications should not be carried out with new brake pads/discs or
linings/drums until the components have bedded-in. New brake friction components will not reach full efficiency until the
bedding-in process is complete.
Test the brakes at several speeds within the normal operating range using both light and heavy pedal pressure. Note any
tendency to snatch, pull or drag, and any undue delay in application or release.
Allow the vehicle to coast and note any tendency to pull to one side, or evidence that the brakes are binding.
After stopping the vehicle (not immediately after a period of heavy braking), carefully check the brake temperature. A disc
which feels hot, or appreciably hotter than the others, indicates that the brake is binding.
After completion of the test, check for:
Oil, coolant, hydraulic, air and fuel leaks
Abnormal temperature of any moving components or assemblies, e.g. wheel hubs, transmission, axle etc., which might
indicate over tightness or lack of lubrication
