WARNING
Off-road driving can be hazardous!·
DO NOT take unnecessary risks.
·
Be prepared for emergencies at all
times.
·
Familiarise yourself with the
recommended driving techniques in
order to minimise risks to yourself, your
vehicle AND your passengers.
·
Remove the CD autochanger (if fitted)
before arduous off-road driving or
wading.
·
Always wear a seat belt for personal
protection in all off-road driving
situations.
·
DO NOT drive if the fuel level is low -
undulating ground and steep inclines
could cause fuel starvation to the engine
and consequent damage to the catalytic
converter.
BASIC OFF-ROAD TECHNIQUES
These basic driving techniques are an
introduction to the art of off-road driving and
do not necessarily provide the information
needed to successfully cope with every single
off-road situation.
We strongly recommend that owners who
intend to drive off-road frequently, should
seek as much additional information and
practical experience as possible.Gear selection - manual gearbox
Correct gear selection is possibly the single
most important factor for safe and successful
off-road driving. While only experience will tell
you which is the correct gear for any section
of ground, the following basic rules apply:
·
NEVER change gear or de-clutch while
negotiating difficult terrain - the drag on
the wheels may cause the vehicle to stop
when the clutch is depressed and
restarting may be difficult.
·
Generally, and especially where slippery or
soft ground conditions prevail, the higher
the gear you select the better.
·
When descending very steep slopes
always select first gear LOW range.
Inexperienced drivers are advised to stop the
vehicle and carefully consider which gear will
be most appropriate for each manoeuvre
before continuing.
Slipping the clutch
Use of excessive clutch slip to prevent the
engine stalling will result in premature clutch
wear. Always select a gear low enough to
enable the vehicle to proceed without needing
to slip the clutch.
DO NOT drive with your foot resting on the
clutch pedal; driving across uneven terrain
could cause you to inadvertently depress the
clutch, resulting in loss of control of the
vehicle. 
						

							Off-road driving
166 Gear selection - automatic gearbox
On automatic models, with the main selector
lever set at D, the gearbox automatically
provides the correct gear for the appropriate
gear range selected (HIGH or LOW).
Remember that position 1 will hold the
gearbox in first gear to give maximum engine
braking when required.
HIGH range gears should be used whenever
possible - only change to LOW range when
ground conditions become very difficult. The
DIFF LOCK should be engaged whenever there
is a risk of loosing wheel grip, and disengaged
as soon as firm, level, non-slippery ground is
reached.
Braking
As far as possible, vehicle speed should be
controlled through correct gear selection.
Application of the brake pedal should be kept
to an absolute minimum. Unless ABS braking
has been fitted, any braking on wet, muddy or
loose surfaces is likely to cause one or more
wheels to lock - the resultant slide could prove
dangerous.
NOTE:
If the correct gear has been selected,
braking will be largely unnecessary.Use of engine for braking
Before descending steep slopes, stop the
vehicle at least its length before the descent,
move the gearshift lever to N, engage LOW
range and then select first or second gear (1
or 2 for automatic transmission) depending
on the severity of the incline.
While descending the slope it should be
remembered that the engine will provide
sufficient braking effort to control the rate of
descent, and that the brakes should not be
applied.
Accelerating
Use the accelerator with care - any sudden
surge of power may induce wheel spin and
result in loss of control of the vehicle. 
						

							Off-road driving
167 Steering
WARNING
DO NOT hold the steering wheel with your
thumbs inside the rim - a sudden kick of
the wheel as the vehicle negotiates a rut or
boulder could seriously injure them.
ALWAYS grip the wheel on the outside of the
rim (as shown) when traversing uneven
ground.
Survey the ground before driving
Before negotiating difficult terrain, it is wise to
carry out a preliminary survey on foot. This
will minimise the risk of your vehicle getting
into difficulty through a previously unnoticed
hazard.Ground clearance
Dont forget to allow for ground clearance
beneath the chassis, axles and under the front
and rear bumpers. Note that the axle
differentials are situated BELOW the chassis
and are positioned slightly to the right of the
centre of the vehicle. Note also that there are
other parts of the vehicle which may come
into contact with the ground - take care not to
ground the vehicle.
Ground clearance is particularly important at
the bottom of steep slopes, or where wheel
ruts are unusually deep and where sudden
changes in the slope of the ground are
experienced.
On soft ground the axle differentials will clear
their own path in all but the most difficult
conditions. However, on frozen, rocky or hard
ground, hard contact between the differentials
and the ground will generally result in the
vehicle coming to a sudden stop.
ALWAYS attempt to avoid obstacles that may
foul the chassis or axle differentials. 
						

							Off-road driving
168 Loss of traction
If the vehicle is immobile due to loss of wheel
grip, the following hints could be of value:
·
Avoid prolonged wheel spin; this will only
make matters worse.
·
Remove obstacles rather than forcing the
vehicle to cross them.
·
Clear clogged tyre treads.
·
Reverse as far as possible, then attempt
an increased speed approach - additional
momentum may overcome the obstacle.
·
Brushwood, sacking or any similar
material placed in front of the tyres may
improve tyre grip.
IMPORTANT INFORMATION
After driving off-road
Before rejoining the public highway, or
driving at speeds above 40 km/h,
consideration should be given to the
following:
·
Wheels and tyres must be cleaned of
mud and inspected for damage.
·
Brake discs and calipers should be
examined and any stones or grit that
may affect braking efficiency
removed.
Servicing requirements
Vehicles operated in arduous conditions,
particularly on dusty, muddy or wet
terrain, and vehicles undergoing frequent
or deep wading conditions will require
more frequent servicing. See Owner
maintenance and contact a Land Rover
dealer for advice.
In addition:
After wading in salt water or driving on
sandy beaches, use a hose to wash the
underbody components and any exposed
body panels with fresh water. This will
help to protect the vehicles cosmetic
appearance. 
						

							Off-road driving
169 DRIVING ON SOFT SURFACES & DRY SAND
The ideal technique for driving on soft sand
requires the vehicle to be kept moving at all
times - soft sand causes excessive drag on
the wheels resulting in a rapid loss of motion
once driving momentum is lost. For this
reason, gear changing (particularly on manual
gearbox vehicles) should be avoided.
·
Engage the DIFF LOCK.
·
Select the highest suitable gear and
REMAIN in that gear until a firm surface is
reached. It is generally advisable to use
LOW range gears, as they will enable you
to accelerate through worsening
conditions without the risk of being unable
to restart.
·
Disengage the DIFF LOCK as soon as firm
ground is reached.Stopping the vehicle on soft ground, in sand
or on an incline
If you do stop the vehicle, remember:
Starting on an incline or in soft ground or
sand may be difficult. Always park on a firm
level area, or with the vehicle facing downhill.
To avoid wheel spin, select second or third
gear, (D for automatic gearbox), and use the
MINIMUM throttle necessary to get the vehicle
moving.
If forward motion is lost, avoid excessive use
of the throttle - this will cause wheel spin and
tend to dig the vehicle into the sand. Clear
sand from around the tyres and ensure that
the chassis and axles are not bearing on the
sand before again attempting to move.
If the wheels have sunk, use an air bag lifting
device or high lift jack to raise the vehicle, and
then build up sand under the wheels so that
the vehicle is again on level ground. If a
restart is still not possible, place sand mats or
ladders beneath the wheels.

170 DRIVING ON SLIPPERY SURFACES
(ice, snow, mud, wet grass)
·
With the DIFF LOCK engaged, select the
highest gear possible.
·
Drive away using the MINIMUM throttle
possible.
·
Drive slowly at all times, keeping braking
to a minimum and avoiding violent
movements of the steering wheel.
·
Disengage the DIFF LOCK as soon as a
non slippery surface is reached.DRIVING ON ROUGH TRACKS
Although rough tracks can sometimes be
negotiated in normal drive, it is advisable to
lock the differential if excessive suspension
movement is likely to induce wheel spin.
On very rough tracks, engage LOW range to
enable a steady, low speed to be maintained
without constant use of the brake and clutch
pedals.
Always disengage the DIFF LOCK when
smooth, firm ground is reached.
