Safety Precautions
Issue 5, January 2010 Workshop Manual 0-0-7
Safety Precautions
All service workshops are a source of potential danger and
repair work should only be performed by technically trained
staff following procedures detailed in this manual. A safety
conscious approach to the performance of all service
procedures must be observed at all times. Statutory
requirements governing all aspects of health and safety at
work including directives for the proper use of materials and
equipment must be implemented.
The following contains a list of particular safety precautions
which should be observed; it is not intended to be
exhaustive.
Battery Disconnection
When a service manual procedure requires the vehicle
battery to be disconnected - always physically disconnect
the vehicle battery earth (Negative) lead.
Do not use the ‘Battery Disconnect Switch’.
After reconnecting the vehicle battery the following items
will have to be reset or re-learnt:
•Radio pre-sets
•Windows
• DTCs will be lost
Air Conditioning (A/C) System
Do not break into the A/C refrigeration system until the
refrigerant has been evacuated using the procedure detailed
in this manual. Do not disconne ct any A/C refrigerant system
pipes unless trained and instructed to do so. The refrigerant
used can cause blindness if allowed to contact your eyes.
Chemical Handling and Storage
Chemicals used in the servicing of motor vehicles include
acids, adhesives, antifreeze, brake fluids, coolants, grease,
oil, paint, resin and solvents. Exposure to certain chemicals
through direct contact or inhalation can be fatal.
Potential hazards may also be present through the incorrect
use, storage and handling of chemicals causing a fire risk.
The following precaution s should be observed.
• Strictly adhere to handling and safety information found on containers and labels.
• Do not store chemicals in unlabelled or incorrectly labelled containers.
• Containers used for storing chemicals should not be left open; there is a risk of spilling , or evaporation of fumes
which may be inflammable or toxic.
• Do not mix chemicals unless instructed to do so following manufacturers guidelines.
• Do not inhale chemical materials to determine identity, they may be toxic.
• Do not use petrol, kerosene, diesel fuel, gas oil, thinners or solvents for washing skin.
• Containers whose capacity is over 25 litres (5 gallons) require a bund wall in order to contain spillages. • Chemicals based on solvents such as paint should not be
sprayed in a confined space; work areas used for such
operations should be well ve ntilated and fume extraction
equipment should be utilised.
• Ensure that adequate ventilation is provided when volatile de-greasing agents are being used.
• Avoid splashing the skin, eyes and clothing .
• Clean chemicals from the skin and clothing as soon as
possible after soiling .
• Wear protective clothing such as goggles, non porous gloves and apron when handling battery acid and other
corrosive and toxic substances.
Electrical Equipment
• Ensure that electrical equipment is in safe working order before use.
• Inspect power leads of all mains electrical equipment for damage and security, and check that it is properly earthed.
• Ensure that electrical equipment is protected by a fuse of the correct current rating .
• Disconnect the battery before commencing repair operations to the electrical sy stem, fuel system and engine
or when working beneath the vehicle.
Exhaust Fumes
Engines should not be run in confined spaces as exhaust
fumes contain harmful and to xic substances including
carbon monoxide which can prove fatal if inhaled. Engines
must only be run where there is fume extraction equipment
in operation or where there is adequate ventilation.
Fire Precautions
• Ensure that a suitable form of fire extinguisher is conveniently located near the work area.
• Keep oils, solvents and combustible materials away from naked flames and other sources of ignition.
• Ensure that NO SMOKING signs are posted around areas where combustible materials and vapour may be present
and ensure that the warnings are strictly observed.
• Ensure that dry sand is availabl e to soak up any spillage of
fuel or other flammable solutions.
• Fume extraction equipment must be available and in full working order to remove combustible and toxic vapours.
• All personnel should be aware of the fire drill procedures and precautions. WAR NI NG
DO NOT SMOKE IN THE VICINITY OF VOLATILE DE- GREASING AGENTS.
WAR NI NG
FUME EXTRACTION EQUIPMENT MUST BE IN
OPERATION WHEN SOLVENTS ARE USED E.G. TRICHLOROETHANE, WHITE SPIRIT, SBP3,
METHYLENE CHLORIDE, PERCHLORETHYLENE.

Battery System (14.01)
Power Supply (14.00)14-1-2 Workshop Manual May 2007
Power Supply (14.00)
Battery System (14.01)
Description
The 12 volt negative earth (‘-’ ve) battery is located under the RH side rear seat and is grounded to the vehicle body.
The battery positive (‘+’ ve) terminal is connected to a battery connect switch. The connect switch may be accessed by
raising the rear seat cushion.
Battery Connect Switch
When the battery connect switch is in an ‘open’ state it
isolates electrical power from all systems except the ‘keep
alive memory’ functions in the PCMs, TCU, radio,
navigation system and door modules.
This function isolates electri cal power from vehicle circuits
under all normal service conditions with the following
exceptions:
• Before any welding or other work which may induce high voltages into the electronic control modules
• Before disconnecting any of the control modules with ‘keep alive memory ’
• Before any major service task (e.g . engine removal)
• Before installing any accessory which involves modification of vehicle wiring
In the above four exceptions the battery earth (‘-’ ve) lead
should be disconnected.
When the battery earth (‘-’ ve) terminal is disconnected,
data held in keep alive memories will be lost. After connecting the battery, the radio preset stations and the
door window controllers will require to be reset (adaptive
learning data in the PCM module will require to be re-
learned by driving the vehicle for some miles in a range of
driving conditions),
driveability may be slightly
compromised until the vehicle systems have completed
their adaptive learning routines again.
Battery Disconnection and Alarm
Activation
The vehicle is installed with an alarm which will be activated
if the battery is disconnected. This alarm is driven by a back
up battery within the alarm sounder unit.
To prevent the alarm from so unding when the battery is
disconnected (for workshop procedures), disconnect the
battery within 10 seconds of switching off the ignition.
Always carry out the following procedures upon connection
of the battery.
• Reset the clock
• Reset the radio preset programmes.
• Reset the window maximum up and maximum down settings.
