INFORMATION JUMP STARTING
WARNING: Hydrogen and oxygen gases
are produced during normal battery
operation. This gas mixture can explode if
flames, sparks or lighted tobacco are brought
near battery. When charging or using a battery in
an enclosed space, always provide ventilation and
shield your eyes.
Keep out of reach of children. Batteries contain
sulphuric acid. Avoid contact with skin, eyes, or
clothing. Also, shield eyes when working near
battery to protect against possible splashing of
acid solution. In case of acid contact with skin,
eyes, or clothing, flush immediately with water for
a minimum of fifteen minutes. If acid is swallowed,
drink large quantities of milk or water, followed by
milk of magnesia, a beaten egg, or vegetable oil.
SEEK MEDICAL AID IMMEDIATELY.
To Jump Start - Negative Ground Battery
WARNING: To avoid any possibility of
injury use particular care when connecting
a booster battery to a discharged battery.
1.Position vehicles so that jump leads will reach,
ensuring that vehiclesDO NOT TOUCH,
alternatively a fully charged slave battery may be
positioned on floor adjacent to vehicle.
2.Ensuring that ignition and all electrical
accessories are switched off, that parking brake
is applied and neutral is selected, connect the
jump leads as follows;
A.Connect one end of first jumper cable to positive
(+) terminal of booster battery.
B.Connect other end of first jumper cable to positive
(+) terminal of discharged battery.
C.Connect one end of second jumper cable to
negative terminal of booster battery.
D.Connect other end of second jumper cable to a
good earth point on the disabled vehicle (eg. engine
front lifting eye, as shown in J6086),NOT TO
NEGATIVE TERMINAL OF DISCHARGED
BATTERY.Keep jumper lead away from moving
parts, pulleys, drive belts and fan blade assembly.
WARNING: Making final cable connection
could cause an electrical arc which if
made near battery could cause an
explosion.
3.If booster battery is installed in another vehicle,
start engine and allow to idle.
4.Start engine of vehicle with discharged battery,
following starting procedure in Owners’Manual.
CAUTION: If vehicle fails to start within a
maximum time of 12 seconds, switch
ignition off and investigate cause. Failing
to follow this instruction could result in
irrepairable damage to catalyst, if fitted.
5.Remove negative (-) jumper cable from the
engine and then terminal of booster battery.
6.Remove positive (+) jumper cable from positive
terminals of booster battery and discharged
battery.

MAINTENANCE BATTERY CONDITION - Td5
Remove
1.Remove drivers seat base.
2.Release clip securing battery cover.
3.Remove battery cover.
NOTE: The vehicle may be fitted with an
alarm and immobilisation system. To
prevent the alarm from sounding, it is
important that the following procedure is used
when disconnecting the battery.
4.Turn the ignition switch to position’II’, and then
to position’0’.
5.Remove the ignition key.
6.Disconnect the vehicle -ve terminal within 15
seconds.
NOTE: Always disconnect the -ve terminal
first. When replacing, connect the +ve
terminal first.
Check
The battery fitted to Td5 models is designed to be
maintenance free, so topping-up is not possible. On
the top of the battery is a battery indicator. When the
indicator shows:
GREEN - The battery is in a good state of charge.
DARK (turning to black) - The battery needs
charging.
CLEAR (or light yellow) - The battery needs
replacing. Do not charge the battery or jump start
the vehicle in this condition.
If the green dot is missing, the battery needs
charging.
NOTE: If the indicator shows clear or
yellow, tap the indicator with the handle of
a screwdriver to disperse any air bubbles.
If the indicator colour remains unchanged, the
battery will need replacing.
Refit
7.Clean and grease battery terminals and leads
with petroleum jelly.
8.Connect leads to battery (+ve first) and tighten
clamp bolts.
9.Fit battery cover and secure with clip.
10.Fit drivers seat base.

DESCRIPTION AND OPERATION GENERAL
The Td5 diesel engine is a 2.5 litre, 5 cylinder, in-line direct injection unit having 2 valves per cylinder, operated by
a single overhead camshaft. The engine emissions on pre EU3 models comply with ECD2 (European Commission
Directive) legislative requirements. EU3 models comply with ECD3 legislative requirements. Both units employ
electronic engine management control, positive crankcase ventilation and exhaust gas recirculation to limit the
emission of pollutants. The unit is water cooled and turbo-charged and is controlled by an electronic engine
management system.
The cylinder block is a monobloc cast iron construction with an aluminium stiffening plate fitted to the bottom of the
cylinder block to improve lower structure rigidity. The cylinder head and sump are cast aluminium. An acoustic
cover is fitted over the upper engine to reduce engine generated noise.
The engine utilises the following features:
Electronic Unit Injectors (EUI’s)controlled by an Engine Management System for precise fuel delivery under
all prevailing operating conditions.
Turbochargingwhich delivers compressed air to the combustion chambers via an intercooler for improved
power output.
Fuel Cooler
Oil Cooler
Centrifuge Oil Filter
Hydraulic Lash Adjusterswith independent finger followers

RECHARGING
Service repair no - 82.30.02
WARNING: The air conditioning system is
charged with a high pressure, potentially
toxic refrigerant. Repairs or servicing must
only be carried out by an operator familiar with
both the vehicle system and the charging and
testing equipment.
WARNING: All operations must be carried
out in a well ventillated area away from
open flame and heat sources.
WARNING: Wear eye and hand safety
protection.
CAUTION: Overcharging air conditioning
system will cause excessive head
pressure.
An air conditioning portable Refrigerant Recovery
Recycling Recharging Station for use with R134a
refrigerant incorporates all the features necessary to
recover R134a refrigerant from the air conditioning
system; to filter and remove moisture; to evacuate and
recharge with the reclaimed refrigerant. The unit can
also be used for performance testing and air
conditioning system analysis.
The operator must adhere to the equipment
manufacturer’s instructions.
Refrigerant Recovery
1.Remove dust caps from high and low pressure
connectors.
2.Connect high and low pressure hoses to
appropriate connections.
3.Open valves on connectors.
4.Turn valves on refrigerant station to correct
positions.
NOTE: Operate the refrigerant station in
accordance with the manufacturers
instructions.
5.Turn Process switch to correct position.
6.Turn Main switch to’ON’.
7.Allow station to recover refrigerant from system.8.Close valves on refrigerant station.
9.Turn Main switch to’OFF’.
10.Close valves on connectors.
11.Disconnect high and low pressure hoses from
connectors.
12.Fit dust caps to connectors.
13.Open tap at rear of station to drain refrigerant oil
recovered from system.
14.Measure and record quantity of refrigerant oil
recovered from system.
15.Close tap at rear of station.
Evacuation
CAUTION: Whenever the refrigerant
system is opened, the receiver/drier must
be renewed immediately before evacuating
and recharging the system.
1.Remove dust caps from high and low pressure
connectors.
2.Connect high and low pressure hoses to
appropriate connections.
3.Open valves on connectors.
4.Turn valves on refrigerant station to correct
positions.
5.Turn Process switch to correct position.
6.Turn Main switch to’ON’.
7.Allow station to evacuate system.
NOTE: If the vacuum reading is below
700mmHg after 15 minutes, suspect a leak
in the system. Partially recharge the
system and check for leaks using an electronic
leak tester. Check suction lines first, then run the
compressor for 5 minutes. Next check the high
pressure lines.
NOTE: The system must be evacuated
immediately before recharging
commences. Delay between evacuation
and recharging is not permitted.

ADJUSTMENT Recharging
WARNING: Refrigerant must always be
recycled before re-use, to ensure that the
purity of the refrigerant is high enough for
safe use within the air conditioning system.
Recycling should always be carried out with
equipment which is design certified by
Underwriter Laboratory Inc. for compliance with
SAE-J1991. Other equipment may not re-cycle the
refrigerant to the required level of purity.
WARNING: A R134a Refrigerant Recovery
Recycling Recharging station must not be
used with any other type of refrigerant.
WARNING: R134a refrigerant from
domestic and commercial sources must
not be used in motor vehicle air
conditioning systems.
CAUTION: When a major repair has been
carried out, a leak test should be carried
out using inert gas.
1.Close valves on refrigerant station.
2.Close valve on oil charger.
3.Disconnect yellow hose from refrigerant station.
4.Remove lid from oil charger.
5.Pour correct quantity of refrigerant oil into oil
charger.
