Gearbox & transmission

TRANSFER GEARBOX
The second gearbox (known as the transfer
box) is used to select either the high or low
range of gears and, in addition, also controls
the central differential (known as the DIFF
LOCK).
High range (H)
The high range of gears should be used for all
normal road driving and also for off-road
driving across dry, level terrain.
Low range (L)
Use low range gears in any situation where
low speed manoeuvring is necessary, such as
reversing a trailer or negotiating a...

85 Advanced method
Changing from high to low on the move:
With the vehicle slowing to a stop and
travelling NO FASTER THAN 5 km/h, depress
the clutch and push the transfer lever into
neutral. Just before the road wheels stop
turning (and with the clutch still depressed)
push the lever fully forward into L (low).
NOTE:
Use positive and confident moves, but
do not rush the gear change.
Changing from low to high on the move:
Changing from L (low) to H (high) can be
achieved without...

86 Selecting diff lock
The diff lock can be engaged or disengaged
either with the vehicle stationary, or when
driving at any road speed. However, with the
vehicle in motion it is ESSENTIAL to be
travelling on firm ground, in a straight line,
and without wheel slip.
WARNING
DO NOT engage the diff lock if one or more
wheels are slipping - this could damage the
transmission. If wheels are slipping, ease
off the accelerator before engaging the diff
lock.
To lock the differential:

Diff lock warning light
The amber warning light on the instrument
panel illuminates when the diff lock is actually
engaged - rather than when it has been
selected. Similarly it will only extinguish when
the diff lock is actually disengaged. This
accounts for a slight delay between diff lock
deselection and the warning light
extinguishing, which is quite normal.
IMPORTANT INFORMATION

If the warning light is obviously reluctant
to extinguish after the diff...

Brakes
88 FOOT BRAKE
As a safety precaution, the hydraulic braking
system operates through dual circuits. If one
circuit should fail, 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
89 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. On
manual gearbox...

Warning light
The anti-lock braking system
warning light illuminates when
the starter switch is turned to position II and
then extinguishes for half a second before
coming on again, it then remains illuminated
until the engine has started and the vehicle
reaches speeds in excess of approximately
7 km/h. If this does not occur, there is a fault
on the system and you should consult your
Land Rover dealer at the earliest opportunity.
If either this light, or the brake fluid warning
light, remains...

Cruise control
91
IMPORTANT INFORMATION
·
DO NOT use cruise control when
using low range transfer gears or
reverse gears.
·
DO NOT use cruise control on
winding or slippery road surfaces, or
in traffic conditions where a
constant speed cannot easily be
maintained.
·
DO NOT rest your foot under the
accelerator pedal while cruise
control is engaged - your foot could
be trapped.
·
ALWAYS switch off the master
switch when you no longer intend to
use cruise control.

Cruise control
92 To increase the set cruising speed:
Press and hold the SET + switch - the vehicle
will accelerate automatically. Release the
switch as soon as the desired speed has been
reached.
Alternatively, the set speed can be increased
incrementally by tapping the SET + switch.
For each five taps the speed will increase by 8
km/h.
Disengaging cruise control
The cruise control will automatically
disengage if the brake or clutch pedals are
pressed, or when the gear lever is moved into
neutral...

Towing & load carrying
93
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. A smooth
start will be achieved with trailers over 2000
kg by moving off in low range then changing
to high range while on the move.
The suspension is designed to cope with a
heavy trailer load without upsetting the
balance or feel of the vehicle. Details of gross
maximum trailer weights are listed on the
following...
