FUEL FILLER FLAP
WARNING
To reduce the risk of any sudden discharge of 
fuel caused by excessive air pressure, the cap 
is designed to allow the fuel tank to vent 
during the first half turn. DO NOT fully remove 
the cap until any pressure has been released.
Take careful note of warning labels located 
around the filler flap.
The fuel filler is located in the rear right-hand 
wing. With the starter switch turned off, press 
the binnacle mounted switch (shown in 
illustration) to release the filler flap.
The filler cap is designed to allow the fuel tank 
to vent during the first half turn. Carefully 
loosen the cap one half turn until resistance is 
felt, and allow fuel tank pressure to be released. 
Once the pressure is released (hissing has 
stopped), it is safe to fully remove the filler cap.When replacing, tighten the cap clockwise until 
you hear the fuel cap ratchet click at least three 
times. If the cap is not fitted correctly, the 
‘Service engine soon’ warning light may 
illuminate.

TYPE OF FUEL
Octane requirements
Premium unleaded gasoline with a CLC or AKI
octane rating of 90 or 92 (95 or 96 RON) should 
be used.
NOTE: Federal law requires that gasoline octane 
ratings be posted on the pumps. The Cost of 
Living Council (CLC) octane rating or Anti 
Knock Index (AKI) octane rating shown is an 
average of Research Octane Number (RON) and 
Motor Octane Number (MON).
Using unleaded fuel with an octane rating lower 
than that recommended can cause persistent, 
heavy ‘engine knock’ (a metallic rapping noise). 
If severe, this can lead to engine damage.
If heavy engine knock is detected when using 
the recommended octane rated fuel, or if steady 
engine knocking is present while maintaining a 
steady speed on level roads, contact your 
retailer for advice.NOTE: An occasional, light, engine knock while 
accelerating or climbing hills is acceptable.
Octane enhancers
The use of octane enhancers is not 
recommended, and may invalidate the vehicle 
warranty. 
NOTE: Reformulated gasolines and gasolines 
that contain detergents, anti-corrosion and 
stability additives are recommended - they will 
help your vehicle maintain the correct level of 
emissions and engine performance.
Driveability
If you encounter driveability, starting and 
stalling problems, especially in high ambient 
temperatures or at high altitude when the 
engine is cold, it may be caused by poor quality 
fuel. Try an alternative brand, and if the problem 
persists, seek advice from your retailer.
Gasoline/oxygenated fuel blends
To avoid invalidating the vehicle warranty, use 
ONLY fuels blended within the following limits:
•Up to 15% of Methyl Tertiary Butyl Ether 
(MTBE) and unleaded fuel mix.
•Up to 15% of Ethyl Tertiary Butyl Ether 
(ETBE) and unleaded fuel mix.
•Up to 10% of Ethanol (Ethyl or grain 
alcohol) and unleaded fuel mix.
Methanol/unleaded fuel blends
In some areas, it is possible to buy unleaded 
fuel that is blended with up to 5% Methanol 
(Methyl or wood alcohol) and cosolvents and 
corrosion preventatives. Using these blends 
can cause driveability problems and damage to 
the fuel system components. Their use may 
also invalidate the vehicle warranty. 
WHEREVER POSSIBLE, AVOID USING FUEL 
CONTAINING METHANOL!
IMPORTANT INFORMATION
ONLY USE UNLEADED FUEL
•Unleaded fuel is essential for proper 
operation of the emission control 
system.
DO NOT use leaded fuel! Your engine is 
designed to use unleaded fuel ONLY.
•Even a very small quantity of leaded 
fuel will damage your vehicles 
emission control system and could 
invalidate the emissions warranty. In 
addition, leaded fuel will damage the 
oxygen sensors in the fuel injection 
system and also seriously damage the 
catalyst in the catalytic converter.
Fuel system cleaning agents should be 
avoided, as many of these products can 
be harmful to gaskets and other materials 
used in fuel system components.

WARNING
Automotive fuels can cause serious injury, 
and even death if misused. 
Methanol/unleaded fuel blends, even in small 
amounts, can cause blindness and possible 
death if swallowed. Additionally, take 
precautions to prevent methanol from coming 
into contact with the skin.
GAS STATION SAFETY
WARNING
Petroleum gases are highly inflammable and, 
in confined spaces, are also extremely 
explosive. 
Always place portable gasoline containers on 
the ground while filling. A fire may result if 
gasoline is pumped into a container that is 
inside a vehicle or on a truck bed. You could 
be burned!
Always take sensible precautions when 
refuelling: 
•Switch off the engine.
•Do not smoke or introduce other ignition 
sources.
•Switch off mobile phones.
•Take care not to spill fuel.
•Do not overfill the tank.
•Do not fill gas cans in the vehicle.
•Do not get back into your vehicle during 
refuelling.
•Use only the hold-open latch provided on 
the gasoline pump. Never jam the latch open 
with some other object.
FUEL FILLING
Gas station pumps are equipped with automatic 
cut-off sensing to avoid fuel spillage. Fill the 
tank SLOWLY until the filler nozzle 
automatically cuts-off the supply. 
DO NOT attempt to fill the tank beyond this 
point or spillage could result due to expansion 
of the fuel.
The reduced diameter filler neck, accepts ONLY 
a narrow filler nozzle of the type found on 
pumps that supply UNLEADED fuel.
NOTE: Ensure the filler cap is fitted correctly 
after refuelling, otherwise the ‘Service engine 
soon’ warning light may illuminate.
EMPTY FUEL TANK
IMPORTANT INFORMATION
DO NOT run the fuel tank dry!
•Running the fuel tank dry could create 
an engine misfire capable of damaging 
the catalytic converter. It will also cause 
the ‘Service engine soon’ warning light 
to illuminate. 
						

							Fuel Filling

FUEL CUT-OFF SWITCH
The fuel cut-off switch is a safety device which, 
in the event of a collision or sudden impact, 
automatically cuts off the fuel supply to the 
engine.
The switch is located on the engine 
compartment bulkhead. After an impact, the 
switch must be reset by pressing the rubber top 
(arrowed in illustration) before the engine can 
be restarted.
WARNING
ALWAYS check for fuel leaks before resetting 
the switch! Activating the switch when the 
fuel system has been damaged (evidenced by 
fuel leakage or odor) will cause additional 
fuel leakage increasing the risk of fire.

							Automatic Transmission
124
Au to matic  Tran smissionGEAR SELECTOR
The Automatic transmission features a four 
speed main gearbox with a torque converter 
and a two speed transfer box. Using the main 
gearbox in conjunction with the transfer 
gearing produces eight forward and two 
reverse speeds.
Main gearbox selector lever
A spring loaded catch restricts movement of 
the lever, thereby preventing inadvertent gear 
selection. Press and hold the trigger mounted 
in the handle of the selector lever (arrowed in 
illustration) to release the catch whilst moving 
the lever to the required position.
NOTE: Gear selection between ‘D’ and ‘3’ in 
high and low range may be made without 
operating the trigger.Selector lever positions
•‘P’ Park 
In this position, the transmission is locked 
to prevent the vehicle from rolling away.
Select ONLY when the vehicle is stationary 
and with the handbrake applied.
•‘R’ Reverse
Select ONLY when the vehicle is stationary.
•‘N’ Neutral 
Use this position when the vehicle is 
stationary and the engine is to idle for a 
short period (at traffic lights, for example).
•‘D’ Drive 
In high range, select for all normal driving 
on good road surfaces; fully automatic gear 
changing occurs on all four forward gears 
according to vehicle speed and accelerator 
position. 
•‘3’ (1st, 2nd and 3rd gears)
Automatic gear changing is limited to first, 
second and third gears only. In high range, 
use this position in congested traffic 
conditions and for town driving.
•‘2’ (1st and 2nd gears)
Automatic gear changing is limited to first 
and second ratios only. In high range, use 
when driving up steep gradients and for 
negotiating very narrow, twisting, roads. 
This position also provides moderate engine 
braking for descending slopes.
•‘1’ (1st gear only)
Use on very severe gradients, particularly 
when towing, and when maximum engine 
braking is required.
WARNING
To reduce the risk of inadvertent vehicle 
movement when parked, always leave the 
vehicle with the gear selector in ‘P’ (Park) 
position, as well as applying the handbrake.

Starting and driving
Drivers unfamiliar with the performance 
characteristics of an automatic gearbox should 
thoroughly familiarize themselves with the 
following instructions before driving.
•Before starting the engine, ensure that both 
foot and parking brakes are applied.
•After starting the engine, KEEP BOTH 
BRAKES APPLIED before and whilst moving 
the selector lever to the required drive 
position.
•Keep the brakes applied until you are ready 
to move - remember, once a drive position 
is selected, an ‘automatic’ will tend to creep 
forward (or backward) without throttle 
application, as soon as the brakes are 
released.
•Never ‘rev’ the engine while selecting a 
forward or reverse drive gear, or while the 
vehicle is stationary with a drive gear 
selected - remember, an ‘automatic’ will 
move immediately once the accelerator 
pedal is pressed.
NOTE: The starter key cannot be removed 
unless the gear selector is in ‘P’ (Park), and it is 
impossible to move the selector lever from ‘P’ 
(Park) unless the foot brake is pressed.
Gear change speeds
With ‘D’ selected, the road speeds at which gear 
changes take place will vary according to the 
position of the accelerator: minimum 
acceleration will result in gear changes at low 
road speed, while larger throttle openings will 
cause the gearbox to delay gear changes until 
faster road speeds have been reached (thereby 
increasing acceleration).
With practice, gear changes can be made to 
occur at a wide range of road speeds depending 
on accelerator pedal pressure.On long inclines the gearbox will sometimes 
change back and forth between gears. This 
occurs because the transmission does not 
include a ratio that is precisely right for the 
particular incline and vehicle loading 
circumstances. However, excessive gear 
changing results in a loss of momentum and is 
wasteful of fuel. It can be prevented by selecting 
the ‘3’ or ‘2’ positions which limit the gearbox 
to lower ratios. 
‘Kick-down’
To provide rapid acceleration for overtaking, 
push the accelerator pedal to the full extent of 
its travel in a single quick movement (this is 
known as ‘kick-down’). Up to a certain speed, 
this will cause an immediate downshift into the 
lowest appropriate gear, followed by rapid 
acceleration. Once the pedal is relaxed, normal 
gear change speeds will resume (dependent 
upon road speed and accelerator pedal 
position).

MODE SWITCH
In High range press the mode switch to select 
‘Sport’ mode (the ‘S’ information light on the 
instrument panel will illuminate).
In Low range press the mode switch to select 
‘Manual’ mode (the ‘M’ information light will 
illuminate).
Press the switch a second time to return the 
gearbox to normal operation.
‘Sport’ mode
With ‘Sport’ mode selected, the gearbox is 
more responsive to accelerator pedal 
movement - downshifts occur earlier and 
upshifts are delayed to make optimum use of 
the engines power while accelerating. Select 
‘Sport’ when increased acceleration is required, 
or when negotiating long inclines or twisting 
roads. Note that driving in ‘Sport’ mode may 
increase fuel consumption.
NOTE: If the ignition switch is turned off while 
‘Sport’ mode is selected, the vehicle will stay in 
‘Sport’ mode when the ignition is next switched 
on.
Moving the transfer gearbox to Low range will 
de-select ‘Sport’ mode; it will stay de-selected 
after moving back to High range.‘Manual’ mode
In Low range, with ‘Manual’ mode selected, the 
automatic transmission functions as a manual 
gearbox requiring the driver to move the 
selector lever manually to change gear 
(‘D’ = 4th gear). Manual mode will provide 
maximum vehicle control and engine braking - 
ideal for use in severe off-road conditions. Note 
that ‘kick-down’ is disabled and that automatic 
downshifts will only occur to prevent the engine 
from stalling.
NOTE: ‘Manual’ mode will be cancelled if the 
ignition is switching off or the transfer gearbox 
is used.

							Transfer Gearbox
127
T ra nsfer Ge arboxTRANSFER GEARBOX
The second gearbox (known as the transfer 
box) is used to select either the high or low 
range of gears. It also has a neutral position 
between high and low.
High range (‘H’)
High range should be used for all normal road 
driving and also for off-road driving across dry, 
level terrain.
Low range (‘L’)
Low range should be used ONLY in situations 
where low speed manoeuvering is necessary, 
such as reversing a trailer or negotiating a 
boulder-strewn river bed. Also use low range 
for more extreme off-road conditions where 
progress in high range cannot be maintained. 
DO NOT attempt to use LOW range gears for 
normal road driving.Transfer box Neutral (‘N’)
With the Transfer box in neutral, drive cannot 
be transmitted to the road wheels, regardless of 
the position of the main gear lever.
Use transfer box neutral when being towed.
H4738 
						

							Transfer Gearbox
128
USING THE TRANSFER GEARBOX
There are two ways of operating the transfer 
gearbox lever:
1.‘Statically’, i.e shifting whilst the vehicle is 
stationary.
2.‘Shift on the move’, this is the 
recommended method, which after a little 
practice, can be carried out smoothly and 
quickly.
‘Static’ method
With the vehicle stationary and the engine 
running, apply the foot brake and then move the 
automatic gearbox selector to the ‘N’ (neutral) 
position.Then move the transfer lever fully 
forward or backwards to the required position. 
If there is a resistance to the gear disengaging, 
do not force the lever. Instead, move the 
automatic gearbox selector to the ‘R’ (reverse) 
position for 2 seconds and then return to the ‘N’ 
(neutral) position and then try range change 
again.
If there is resistance to the gear engaging, 
(from the neutral position to the either high or 
low), do not force the lever. Instead:
1.Apply handbrake.
2.With the automatic gearbox still in ‘N’ 
(neutral), momentarily rev the engine 
whilst applying pressure to the transfer 
box lever to engage gear.
3.Select appropriate main gearbox gear to 
pull away.
‘Shift on the move’ method 
With the vehicle driving forwards, reduce (or 
increase) the speed of the vehicle to 5 mph (8 
km/h), then: 
1.Release the accelerator and select auto 
gearbox ‘N’.
2.As the vehicle reaches walking pace, move 
the transfer lever to the required ‘H’ or ‘L’ 
position. (Use positive and confident 
moves, but do not rush the gear change).3.Finally, reselect appropriate gear with the 
main gear selector and continue driving as 
normal.

THE DIFFERENTIAL LOCK*
Unlike most other four-wheel-drive vehicles, all 
Land Rover products have permanent 
four-wheel drive.
Discovery is enhanced by the inclusion of an 
optional lockable differential (diff lock) 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 feature enhances traction on difficult 
off-road surfaces. However, with the differential 
unlocked, the different running requirements of 
the two axles can be accommodated, thereby 
enabling Discovery to operate permanently in 
four-wheel drive for both normal AND off-road 
use.Selecting diff lock
The diff lock can be engaged or disengaged 
either with the vehicle stationary, or when 
driving at any speed. However, with the vehicle 
in motion, it is ESSENTIAL to be travelling on 
firm ground, in a straight line, and without 
wheel slip.
To lock the differential
Move the transfer gear lever to the left - from 
either ‘H’ (high) or ‘L’ (low) gearbox (the 
warning light on the instrument panel will 
illuminate). 
To unlock the differential
Move the transfer gear lever to the right - to 
either ‘H’ (high) or ‘L’ (low) gearbox as 
required; when the diff lock disengages, the 
warning light will extinguish.
When to use the diff lock
As a general rule, the differential should be 
locked only in order to drive on loose or 
slippery off-road surfaces. ALWAYS unlock the 
differential for normal road driving or as soon 
as a surface giving good grip is reached 
whether high or low gears are selected.

IMPORTANT INFORMATION
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.
