DRIVING PRECAUTIONS
WARNING
Utility vehicles have a significantly higher 
roll-over rate than other types of vehicles. 
Since these vehicles are designed to be 
operated both on and off-road, these vehicles 
have a higher ground clearance and hence a 
higher center of gravity. Such a feature has 
been associated with an increased risk of 
vehicle roll-over. An advantage associated 
with higher ground clearance vehicles is a 
better view of the road, allowing the driver to 
anticipate problems. Another factor shown to 
significantly increase roll-over risk is 
unauthorized vehicle modifications such as 
fitting incorrect specification tires (see 
‘WHEELS & TIRES’, page 235), oversize tires, 
body lifting, incorrect springs/dampers, 
incorrect vehicle loading/trailer towing.
However, on-road crash data also indicates 
that driver behaviour is a greater factor than a 
high center of gravity in determining a 
vehicles overall roll-over rate. The single 
most effective driver behaviour that can 
reduce the risk of injury or death in all crashes 
including roll-over, is to ALWAYS WEAR 
YOUR SEAT BELT and to properly restrain all 
child passengers on the second row seats in 
appropriate child safety seats. In a roll-over 
crash, an unbelted person is significantly 
more likely to die than a person wearing a 
seat belt. Other measures that can reduce the risk of 
injury and death from vehicle crashes and 
roll-over are:
•Limit speed. Posted speed limits should 
never be exceeded, and you should always 
adjust your speed as traffic, weather, road 
or other conditions dictate. Always use your 
common sense and good judgement.
•Take curves at reasonable speeds, avoiding 
unnecessary braking and steering.
•Drive defensively. Be aware of traffic, road 
and weather conditions. Avoid risk taking 
behaviour such as following too close, rapid 
lane changing or abrupt maneuvers.
•Assume that pedestrians or other drivers 
are going to make mistakes. Anticipate what 
they might do. Be ready for their mistakes.
•Avoid distractions such as cellular phone 
calling, reading, eating, drinking or reaching 
for items on the floor.
•Before changing lanes, check your mirrors 
and flash your turn signal lights.
•Always leave room for unexpected events 
such as sudden braking.
•Never operate your vehicle when you have 
consumed alcohol, are sleepy or fatigued or 
have taken any medications that affect 
judgement, reflexes or alertness.
•Many vehicle rollovers occur when a driver 
attempts to bring a vehicle back onto the 
road after some or all of the wheels drift 
onto the shoulder of the road, especially 
when the shoulder is unpaved. If you find 
yourself in such a situation, do not initiate 
any sharp or abrupt steering and/or braking 
maneuvers to re-enter the roadway. Instead, 
let the vehicle slow down as much as safely 
possible before attempting to re-enter the 
roadway and keep your wheels as straight 
as possible while re-entering the roadway.

FUEL ECONOMY
Fuel consumption is influenced by two major 
factors: 
•How your vehicle is maintained.
•How you drive your vehicle.
To obtain optimum fuel economy, it is essential 
that your vehicle is maintained in accordance 
with the manufacturers service schedule. 
Items such as the condition of the air cleaner 
element, tire pressures and wheel alignment 
will have a significant effect on fuel 
consumption. But, above all, the way in which 
you drive is most important. The following hints 
may help you to obtain better value from your 
motoring: 
•Avoid unnecessary, short, start-stop 
journeys.
•Avoid fast starts by accelerating gently and 
smoothly from rest.
•Do not drive in the lower gears for longer 
than necessary.
•Decelerate gently and avoid sudden and 
heavy braking.
•Anticipate obstructions and adjust your 
speed accordingly well in advance.
•When stationary in traffic, select neutral to 
improve fuel economy and air conditioning 
performance.
BREAKDOWN SAFETY
IMPORTANT INFORMATION
Remember the breakdown safety code
If a breakdown occurs while travelling:
•Wherever possible, consistent with 
road safety and traffic conditions, the 
vehicle should be moved off the main 
thoroughfare, preferably onto the 
shoulder as far as possible. If a 
breakdown occurs on a motorway, pull 
well over to the inside of the hard 
shoulder.
•Switch on hazard lights.
•If possible, position a warning triangle 
or a flashing amber light at an 
appropriate distance from the vehicle to 
warn other traffic of the breakdown, 
(note the legal requirements of some 
countries).
•Consider evacuating passengers 
through the doors facing away from 
traffic, to a safe area away from the 
vehicle, as a precaution in case your 
Discovery is accidentally struck by 
another vehicle.

Ma inte na nceROUTINE MAINTENANCE
Regular systematic maintenance is the key to 
ensuring the continued reliability and efficiency 
of your vehicle.
Maintenance is the owners responsibility and 
you must ensure that owner maintenance 
operations, oil services, inspections and brake 
fluid and coolant changes are carried out when 
required and according to the manufacturers 
recommendations.
The routine maintenance requirements for your 
vehicle are shown in the Passport to Service 
book. Most of this necessary workshop 
maintenance requires specialised knowledge 
and equipment, and should preferably be 
entrusted to a Land Rover retailer.
Passport to Service book
The Passport to Service book includes a 
Service Record section, which enables a record 
to be kept of all the oil services and inspections 
that are carried out on the vehicle. This section 
of the book also provides a facility for the dealer 
to record brake fluid and ancillary drive belt 
changes, as well as the fitting of replacement 
airbag modules. 
Ensure your retailer signs and stamps the book 
after each oil service and inspection.Brake fluid/component replacement
Brake fluid must be completely renewed every 
30,000 miles (48,000 km) or 24 months, 
whichever is the sooner.
In addition, it is recommended that at 90,000 
mile (144,000 km) intervals or every 6 years, 
whichever is the sooner, all hydraulic brake 
fluid seals and flexible hoses are renewed. All 
working surfaces of the caliper cylinders are 
examined and the components renewed where 
necessary. Under arduous operating 
conditions, these intervals may need to be 
reduced. Please consult your Land Rover 
retailer.
Coolant replacement
The engine coolant (anti-freeze and water 
solution) needs to be replaced every 
30,000 miles (48,000 km) or 24 months, 
whichever is the sooner.

OWNER MAINTENANCE
In addition to the routine services and 
inspections referred to previously, a number of 
simple checks must be carried out more 
frequently. You can carry out these checks 
yourself and advice is given on the pages that 
follow.
Any significant or sudden drop in fluid levels, 
or uneven tire wear, should be reported to a 
dealer without delay.
Daily checks
•Operation of lights, horn, direction 
indicators, wipers, washers and warning 
lights.
•Operation of seat belts and brakes.
•Look for fluid deposits underneath the 
vehicle that might indicate a leak 
(condensation drips from the air 
conditioning are normal).
Weekly checks
•Engine oil level.
NOTE: The engine oil level should be 
checked more frequently if the vehicle is 
driven for prolonged periods at high speeds.
•Coolant level.
•Brake fluid level.
•Power steering fluid level.
•Screen washer fluid level.
•Active cornering enhancement fluid level
•Tire pressures and condition.
•Operate air conditioning.
All fluid specifications and capacities are shown 
in ‘LUBRICANTS AND FLUIDS’, page 229.WARNING
If brake pedal travel is unusually long or if 
there is any significant loss of brake fluid, 
contact your retailer immediately. Driving 
under such conditions could result in 
extended stopping distances or complete 
brake failure.
Driving in arduous conditions
IMPORTANT INFORMATION
Special operation conditions
When a vehicle is operated in extremely 
arduous conditions, more frequent 
attention must be paid to servicing 
requirements.
For example: if your vehicle experiences 
deep wading conditions, even DAILY 
servicing could be necessary to ensure the 
continued safe and reliable operation of the 
vehicle.
Arduous driving conditions include:
•Repeated short distance driving (e.g. 
up to 6 miles (10 km), stop-start 
driving or idling for long periods.
•Driving in dusty and/or sandy 
conditions.
•Driving on rough and/or muddy roads 
and/or wading.
•Driving in extremely hot conditions.
•Towing a trailer or driving in 
mountainous conditions.
Contact a Land Rover retailer for advice.

SAFETY IN THE GARAGE
WARNING
Cooling fans may continue to operate after the 
engine is switched off. When the engine is 
hot, the cooling fans may also COMMENCE 
operating after the engine is switched off and 
continue operating for up to 10 minutes. To 
avoid injury, keep clear of all fans and 
remove any loose clothing while working in 
the engine compartment.
Whenever you need to carry out maintenance 
on your vehicle, observe the following safety 
precautions at all times:
•Keep your hands, hair, tools and clothing 
away from drive belts and pulleys.
•If the vehicle has been driven recently, DO 
NOT TOUCH exhaust and cooling system 
components until the engine has cooled.
•DO NOT TOUCH electrical leads or 
components while the engine is running, 
or with the starter switch turned on.
•NEVER leave the engine running in an 
unventilated area - exhaust gases are 
poisonous and extremely dangerous.
•DO NOT work beneath the vehicle with the 
wheel changing jack as the only means of 
support.
•Ensure sparks and naked lights are kept 
away from the engine compartment.
•Wear protective clothing, including, 
where practicable, gloves made from an 
impervious material.
•Remove metal wrist bands and jewellery 
before working in the engine 
compartment.
•DO NOT allow tools or metal parts of the 
vehicle to make contact with the battery 
leads or terminals.
WARNING
Under no circumstances should any part of 
the fuel system be dismantled or replaced by 
anyone other than a suitably qualified motor 
vehicle technician. Failure to comply with this 
instruction may result in fuel spillage with a 
consequent serious risk of fire.
Poisonous fluids
Fluids used in motor vehicles are poisonous 
and should not be consumed or brought into 
contact with open wounds. These include 
battery acid, anti-freeze, brake and power 
steering fluid, petrol, engine oil and windscreen 
washer additives. 
For your own safety, ALWAYS read and obey all 
instructions printed on labels and containers.
Used engine oil
Prolonged contact with engine oil may cause 
serious skin disorders, including dermatitis and 
cancer of the skin. ALWAYS wash thoroughly 
after contact.
It is illegal to pollute drains, water courses 
or soil with toxic chemicals such as used 
engine oil. Use authorised waste disposal sites 
to dispose of used oil and toxic chemicals. 
						

							Maintenance
168
EMISSION CONTROL
Your vehicle is fitted with various items of 
emission and evaporative control equipment 
designed to meet specific territorial 
requirements. You should be aware that 
unauthorised replacement, modification or 
tampering with this equipment by an owner or 
repair shop may be unlawful and subject to 
legal penalties.
In addition, engine settings must not be 
tampered with. These have been established to 
ensure that your vehicle complies with 
stringent exhaust emission regulations. 
Incorrect engine settings may adversely affect 
exhaust emissions, engine performance and 
fuel consumption, as well as causing high 
temperatures, which will result in damage to 
the catalytic converter and the vehicle.
NOTE: While Land Rover North America Inc. 
maintains that an authorised Land Rover 
retailer is best equipped to carry out repairs and 
maintenance on the emission control system, 
such work may be carried out by any competent 
automotive repair shop or individual using 
certified parts.
ROAD TESTING ON DYNAMOMETERS 
(‘rolling roads’)
Because your vehicle is equipped with anti-lock 
brakes and permanent four-wheel drive, it is 
essential that any dynamometer testing is 
carried out ONLY by a qualified person familiar 
with appropriate testing and safety procedures 
and ONLY on a four-wheel drive dynamometer.
