MAIN GEARBOX
Your vehicle features a five speed main
gearbox and a two speed transfer box. In
addition, a centre differential in the transfer
box distributes the drive to the front and rear
axles, providing permanent four wheel drive.
By using the main gearbox in conjunction with
the transfer gears, ten forward and two
reverse speeds are available.
The gear positions for the main gearbox are
shown on the gear lever knob. Note that when
the gearbox is in neutral, the gear lever...

TRANSFER GEARBOX
The second gear lever is used to select either
the high or low range of gears in the transfer
gearbox and, in addition, also controls the
centre differential (known as the DIFF LOCK).
High range (H)
Use high range for all normal road driving and
also for off-road driving across dry, level
terrain.
Low range (L)
Use low range gears when moving off from
rest when towing a heavy load, or in any
situation where low speed manoeuvring is
necessary, such as reversing a...

56 USING THE TRANSFER GEARBOX
With the vehicle stationary and the engine
running, depress the clutch and then move
the lever fully forward (or backwards) in TWO
distinct but positive moves - high to
neutral.... neutral to low (or vice versa).
If there is resistance to the gear engaging, do
not force the lever. Instead, with the main
lever in gear, release the clutch momentarily
and then try again.
Changing from low to high on the move:
Changing from L (low) to H (high) can be...

THE DIFFERENTIAL LOCK
Unlike other four wheel drive vehicles, all Land
Rover products have permanent four wheel
drive. This is achieved by the inclusion of a
lockable differential between the front and rear
drive shafts. With the differential locked, the
drive shafts to front and rear axles are (in
effect) joined together, causing both to rotate
at the same speed. This is a normal feature
with all four wheel drive vehicles and
enhances traction on difficult off-road
surfaces....

58 When to use the diff lock
As a general rule, the differential should only
be locked in order to drive off-road on loose
and slippery surfaces. ALWAYS unlock the
differential for normal road driving or as soon
as a hard grippy surface is reached whether
high or low gears are selected.
NOTE:A valuable introduction to off-road
driving, which includes many useful
references to the transfer gearbox and diff
lock, is included in the Off-road driving
section of the handbook.

Brakes
59 BRAKING SYSTEM
As a safety precaution, the hydraulic braking
system operates through dual circuits. If one
circuit fails, the other will continue to function,
but increased brake pedal travel and longer
stopping distances will be experienced.
Servo assistance
The braking system is servo assisted, but
ONLY when the engine is running. Without
this assistance, greater braking effort is
necessary to safely control the vehicle,
resulting in longer stopping distances. Always
observe the following...

Brakes
60 HANDBRAKE
Unlike most other vehicles, the handbrake
operates on the rear propeller shaft, and NOT
on the road wheels. This may result in slight
movement of the vehicle after the handbrake
is applied.
To engage the handbrake, depress the button
and pull the lever up.
To release, pull the lever up slightly, depress
the button and lower the lever.
Always apply the handbrake fully whenever
you park.
When parking on a slope, do not rely on the
handbrake alone to hold the vehicle, park in a
low...

Towing & load carrying
61 TOWING
The torque ranges of Land Rover engines
allow maximum-weight loads to be pulled
smoothly from standstill, and reduce gear
changing on hills or rough terrain.
The suspension is designed to cope with a
heavy trailer load without upsetting the
balance or feel of the vehicle.
WARNING
Only fit towing accessories that have been
designed and approved by Land Rover.
Ensure that the gross weight and maximum
rear axle weight are not exceeded.
When preparing your vehicle for...

NOTE:Towing regulations vary from country to country. It is very important to ensure that
national regulations governing towing weights and speed limits are observed (refer to the relevant
national motoring organisation for information). The following maximum permissible towed
weights refer to the vehicles design limitations and NOT to any specific territorial restriction.

Towing & load carrying
63 Coupled braking systems
In order to tow a trailer with a weight in
excess of 3,500 kg, the vehicle must be
adapted to operate a coupled brake system. If
this adaptation is carried out, the vehicle
identification number plate (VIN) must be
changed to show the increased train weight.
Revised VIN plates may be obtained from
Land Rover; these will be issued subject to
satisfactory proof that the vehicle has been
fitted with an approved conversion.
NOTE:Above 300 metres (1,000 feet)...
