LIFTING AND TOWING
08-2
Before commencing work on underside of vehicle re-
check security of vehicle on stands.
WARNING: Always chock the wheels when
jacking. The hand brake acts on the the
transmission, not the rear wheels, and may be
ineffective when the wheels are off the ground.
Reverse procedure when removing vehicle from
stands.
Hydraulic ramps
Use only a 'drive on' type ramp which supports a
vehicle by it's own road wheels. If a 'wheel free'
condition is required, use a 'drive on' ramp
incorporating a 'wheel free' system that supports
under axle casings. Alternatively, place vehicle on a
firm, flat floor and support on axle stands.
TOWING
Towing
The vehicle has permanent four wheel drive. The
following towing instructions must be adhered
to:
Towing on 4 wheels with driver
Turn ignition key to position '1' to release steering
lock.
Select neutral in main gearbox and transfer gearbox.
Secure tow rope, chain or cable to towing eye.
Release the handbrake.
The brake servo and power assisted steering
system will not be functional without the engine
running. Greater pedal pressure will be required
to apply the brakes, the steering system will
require greater effort to turn the front road
wheels. The vehicle tow connection should be
used only in normal road conditions, 'snatch'
recovery should be avoided.
Suspended tow
To prevent vehicle damage, front or rear
propeller shaft MUST BE removed, dependent
upon which axle is being trailed.
Mark propeller shaft drive flanges at transfer box and
axles with identification lines to enable the propeller
shaft to be refitted in its original position.

CAPACITIES, FLUIDS, LUBRICANTS AND SEALANTS
09-2
Fluids
Anti-freeze
Use Havoline Extended Life Coolant (XLC), or any
ethylene glycol based anti-freeze (containing no
methanol) with only Organic Acid Technology (OAT)
corrosion inhibitors, to protect the cooling system
CAUTION: No other anti-freeze should be used
with Havoline Extended Life Coolant.
The cooling system should be drained, flushed and
refilled with the correct amount of anti-freeze solution
at the intervals given on the Service Maintenance
Check Sheet.
After filling with anti-freeze solution, attach a warning
label to a prominent position on the vehicle stating
the type of anti-freeze contained in the cooling
system to ensure that the correct type is used for
topping-up.
Brake/Clutch fluid
Use only DOT 4 brake fluid.
PAS fluid
Use Texaco cold climate power assisted steering
fluid PSF 14315.
ACE fluid
Where ambient temperature falls below -20° C (-4°
F), use only Texaco cold climate power assisted
steering fluid PSF 14315. Where ambient
temperature remains above -20° C (-4° F), use either
Texaco cold climate power assisted steering fluid ,
Dexron 11 or Dexron 111 non-synthetic fluid.
Air conditioning
Use only refrigerant R134a.
Refrigerant oil
Use only Nippon Denso ND-oil 8.
Refrigerant oil absorbs water and must not be stored
for long periods. Do not pour unused oil back into the
container.
NOTE: The total quantity of refrigerant oil in the
system is 180 ml.
CAUTION: Do not use any other type of
refrigerant oil.
Anti-Freeze Concentration
The overall anti-freeze concentration should not fall,
by volume, below 50% to ensure that the anti-
corrosion properties of the coolant are maintained.
Anti-freeze concentrations greater than 60% are not
recommended as cooling efficiency will be impaired.
The following recommended quantities of anti-freeze
will provide frost protection to -48°C (-53°F):
Engine - TD5
Engine - V8
Concentration 50%
Amount of Anti-freeze 4 litres
Concentration 50%
Amount of Anti-freeze 6.5 litres
