LIFTING AND TOWING
LIFTING
The following instructions must be carried out before
raising the vehicle off the ground.
lUse a solid level ground surface.
lApply hand brake.
lSelect 'P' (Automatic gearbox) or 1st gear
(Manual gearbox) in main gearbox.
lSelect Low range in transfer gearbox.
To avoid damage occurring to the under body
components of the vehicle the following jacking
procedures must be adhered to.
DO NOT POSITION JACKS OR AXLE STANDS
UNDER THE FOLLOWING COMPONENTS:
lBody structure
lBumpers
lFuel lines
lBrake lines
lFront radius arms
lPanhard rod
lSteering linkage
lRear trailing arms
lFuel tank
lEngine sump
lGearbox bell housing
Vehicle jack
The jack provided with the vehicle is only intended for
use in an emergency, for changing a tyre. DO NOT
use the jack for any other purpose. Refer to Owner's
Handbook for vehicle jack location points and
procedure. Never work under a vehicle supported
solely by the vehicle jack.
Hydraulic jack
A hydraulic jack with a minimum 1500 kg, 3,300 lbs
load capacity must be used. Do not commence
work on the underside of the vehicle until
suitable axle stands have been positioned under
the axle.
WARNING: Always chock the wheels when
jacking. The hand brake acts on the
transmission, not the rear wheels, and may be
ineffective when the wheels are off the ground.Raising and supporting the vehicle
Position cup of hydraulic arm under differential
casing (1).The differential casing is not central to
the axle. Care should be taken when raising the
front road wheels off the ground as the rear axle
has less sway stiffness.
Raise vehicle to enable an axle stand to be installed
under left hand axle tube (2).
Position an axle stand under right hand axle tube (4).
Carefully lower jack until vehicle sits securely on both
axle stands, remove jack.
Alternatively, the axle stands can be positioned
under the chassis longitudinals at the front and/or
rear of the vehicle.
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.

CAPACITIES, FLUIDS AND LUBRICANTS
09-2
Refrigerant - A/C system
Fluids
Anti-freeze
Use Havoline Extended Life Coolant (XLC), or any
ethylene glycol based anti-freeze (containing no
methanol) with only Organic Acid Technology
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/ACE fluid
Use Texaco cold climate power assisted steering
fluid 14315.
Air conditioning
Use only refrigerant R134a.
Refrigerant oil
Use only NipponDenso ND-oil 8 or Unipart 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.
