Safety first!0•5
Working on your car can be dangerous.
This page shows just some of the potential
risks and hazards, with the aim of creating a
safety-conscious attitude.
General hazards
Scalding
• Don’t remove the radiator or expansion
tank cap while the engine is hot.
• Engine oil, automatic transmission fluid or
power steering fluid may also be dangerously
hot if the engine has recently been running.
Burning
• Beware of burns from the exhaust system
and from any part of the engine. Brake discs
and drums can also be extremely hot
immediately after use.
Crushing
• When working under or near
a raised vehicle,
always
supplement the
jack with axle
stands, or use
drive-on
ramps.
Never
venture
under a car which
is only supported by a jack.
• Take care if loosening or tightening high-
torque nuts when the vehicle is on stands.
Initial loosening and final tightening should
be done with the wheels on the ground.
Fire
• Fuel is highly flammable; fuel vapour is
explosive.
• Don’t let fuel spill onto a hot engine.
• Do not smoke or allow naked lights
(including pilot lights) anywhere near a
vehicle being worked on. Also beware of
creating sparks
(electrically or by use of tools).
• Fuel vapour is heavier than air, so don’t
work on the fuel system with the vehicle over
an inspection pit.
• Another cause of fire is an electrical
overload or short-circuit. Take care when
repairing or modifying the vehicle wiring.
• Keep a fire extinguisher handy, of a type
suitable for use on fuel and electrical fires.
Electric shock
• Ignition HT
voltage can be
dangerous,
especially to
people with heart
problems or a
pacemaker. Don’t
work on or near the
ignition system with
the engine running or
the ignition switched on.• Mains voltage is also dangerous. Make
sure that any mains-operated equipment is
correctly earthed. Mains power points should
be protected by a residual current device
(RCD) circuit breaker.
Fume or gas intoxication
• Exhaust fumes are
poisonous; they often
contain carbon
monoxide, which is
rapidly fatal if inhaled.
Never run the
engine in a
confined space
such as a garage
with the doors shut.
• Fuel vapour is also
poisonous, as are the vapours from some
cleaning solvents and paint thinners.
Poisonous or irritant substances
• Avoid skin contact with battery acid and
with any fuel, fluid or lubricant, especially
antifreeze, brake hydraulic fluid and Diesel
fuel. Don’t syphon them by mouth. If such a
substance is swallowed or gets into the eyes,
seek medical advice.
• Prolonged contact with used engine oil can
cause skin cancer. Wear gloves or use a
barrier cream if necessary. Change out of oil-
soaked clothes and do not keep oily rags in
your pocket.
• Air conditioning refrigerant forms a
poisonous gas if exposed to a naked flame
(including a cigarette). It can also cause skin
burns on contact.
Asbestos
• Asbestos dust can cause cancer if inhaled
or swallowed. Asbestos may be found in
gaskets and in brake and clutch linings.
When dealing with such components it is
safest to assume that they contain asbestos.
Special hazards
Hydrofluoric acid
• This extremely corrosive acid is formed
when certain types of synthetic rubber, found
in some O-rings, oil seals, fuel hoses etc, are
exposed to temperatures above 400
0C. The
rubber changes into a charred or sticky
substance containing the acid. Once formed,
the acid remains dangerous for years. If it
gets onto the skin, it may be necessary to
amputate the limb concerned.
• When dealing with a vehicle which has
suffered a fire, or with components salvaged
from such a vehicle, wear protective gloves
and discard them after use.
The battery
• Batteries contain sulphuric acid, which
attacks clothing, eyes and skin. Take care
when topping-up or carrying the battery.
• The hydrogen gas given off by the battery
is highly explosive. Never cause a spark or
allow a naked light nearby. Be careful when
connecting and disconnecting battery
chargers or jump leads.
Air bags
• Air bags can cause injury if they go off
accidentally. Take care when removing the
steering wheel and/or facia. Special storage
instructions may apply.
Diesel injection equipment
• Diesel injection pumps supply fuel at very
high pressure. Take care when working on
the fuel injectors and fuel pipes.
Warning: Never expose the hands,
face or any other part of the body
to injector spray; the fuel can
penetrate the skin with potentially fatal
results.
Remember...
DO
• Do use eye protection when using power
tools, and when working under the vehicle.
• Do wear gloves or use barrier cream to
protect your hands when necessary.
• Do get someone to check periodically
that all is well when working alone on the
vehicle.
• Do keep loose clothing and long hair well
out of the way of moving mechanical parts.
• Do remove rings, wristwatch etc, before
working on the vehicle – especially the
electrical system.
• Do ensure that any lifting or jacking
equipment has a safe working load rating
adequate for the job.
A few tips
DON’T
• Don’t attempt to lift a heavy component
which may be beyond your capability – get
assistance.
• Don’t rush to finish a job, or take
unverified short cuts.
• Don’t use ill-fitting tools which may slip
and cause injury.
• Don’t leave tools or parts lying around
where someone can trip over them. Mop
up oil and fuel spills at once.
• Don’t allow children or pets to play in or
near a vehicle being worked on.

When jump-starting a car using a
booster battery, observe the following
precautions:
4Before connecting the booster
battery, make sure that the ignition
is switched off.
4Ensure that all electrical equipment
(lights, heater, wipers, etc) is
switched off.
4Take note of any special precautions
printed on the battery case.4Make sure that the booster battery
is the same voltage as the
discharged one in the vehicle.
4If the battery is being jump-started
from the battery in another vehicle,
the two vehicles MUST NOT TOUCH
each other.
4Make sure that the transmission is in
neutral (or PARK, in the case of
automatic transmission).
Jump starting will get you
out of trouble, but you must
correct whatever made the
battery go flat in the first
place. There are three possibilities:
1) The battery has been drained by
repeated attempts to start, or by
leaving the lights on.
2) The charging system is not working
properly (alternator drivebelt slack or
broken, alternator wiring fault or
alternator itself faulty).
3) The battery itself is at fault (electrolyte
low, or battery worn out).
Connect one end of the red jump lead
to the positive (+) terminal of the flat
batteryConnect the other end of the red lead
to the positive (+) terminal of the
booster batteryConnect one end of the black jump lead
to the negative (-) terminal of the
booster battery
Connect the other end of the black
jump lead to a bolt or bracket on the
engine block, well away from the
battery, on the vehicle to be started
123

Make sure that the jump leads will not
come into contact with the fan,
drivebelts or other moving parts of the
engine5
Start the engine using the booster
battery, then with the engine running at
idle speed, disconnect the jump leads
in the reverse order of connection6

Roadside repairs0•9
When all else fails, you may find yourself
having to get a tow home – or of course you
may be helping somebody else. Long-distance
recovery should only be done by a garage or
breakdown service. For shorter distances, DIY
towing using another car is easy enough, but
observe the following points:
MUse a proper tow-rope – they are not
expensive. The vehicle being towed must
display an ‘ON TOW’ sign in its rear window.
MAlways turn the ignition key to the ‘on’
position when the vehicle is being towed, so
that the steering lock is released, and that the
direction indicator and brake lights will work.
MOnly attach the tow-rope to the towing
eyes provided. On some models with energy-
absorbing bumpers there are no front towing
eyes; on these vehicles the tow-rope shouldbe attached around the rear arm of the lower
control arm so that the rope passes on the
inside of the coil spring.
MBefore being towed, release the handbrake
and select neutral on the transmission.
MNote that greater-than-usual pedal
pressure will be required to operate the
brakes, since the vacuum servo unit is only
operational with the engine running.
MOn models with power steering, greater-
than-usual steering effort will also be required.
MThe driver of the car being towed must
keep the tow-rope taut at all times to avoid
snatching.
MMake sure that both drivers know the route
before setting off.
MOnly drive at moderate speeds and keep
the distance towed to a minimum. Drivesmoothly and allow plenty of time for slowing
down at junctions.
MOn models with automatic transmission,
special precautions apply. If in doubt, do not
tow, or transmission damage may result.
Caution: On models with automatic
transmission, if the vehicle is to be towed
with its rear wheels on the ground, and
extra 1.7 litres of fluid should be added to
the transmission, prior to towing (this extra
fluid must be drained before driving the
vehicle). Even with the extra fluid added to
the transmission, do not tow the vehicle at
speeds in excess of 30 mph (50 kmh) or for
a distance of greater than 15 miles (25 km).
If towing speed/distance are to exceed
these limits, then the vehicle must be
towed with its rear wheels off the ground.
Towing
Puddles on the garage floor or drive, or
obvious wetness under the bonnet or
underneath the car, suggest a leak that needs
investigating. It can sometimes be difficult to
decide where the leak is coming from,
especially if the engine bay is very dirty
already. Leaking oil or fluid can also be blown
rearwards by the passage of air under the car,
giving a false impression of where the
problem lies.Warning: Most automotive oils
and fluids are poisonous. Wash
them off skin, and change out of
contaminated clothing, without
delay.The smell of a fluid leaking
from the car may provide a
clue to what’s leaking. Some
fluids are distinctively
coloured. It may help to clean the car and
to park it over some clean paper as an
aid to locating the source of the leak.
Remember that some leaks may only
occur while the engine is running.
Sump oil Gearbox oil
Brake fluid
Power steering fluid
Oil from filter
Antifreeze
Engine oil may leak from the drain plug......or from the base of the oil filter.
Leaking antifreeze often leaves a crystalline
deposit like this.Gearbox oil can leak from the seals at the
inboard ends of the driveshafts.
A leak occurring at a wheel is almost
certainly brake fluid.Power steering fluid may leak from the pipe
connectors on the steering rack.

Weekly checks0•11
Engine oil level
Before you start
4Make sure that your car is on level ground.
4Check the oil level before the car is driven,
or at least 5 minutes after the engine has been
switched off.
The correct oilModern engines place great demands on their
oil. It is very important that the correct oil for
your car is used (See “Lubricants, fluids and
tyre pressures”).
Car care
l If you have to add oil frequently, you should
check whether you have any oil leaks. Place
some clean paper under the car overnight,
and check for stains in the morning. If there
are no leaks, the engine may be burning oil
(see “Fault finding”).
lAlways maintain the level between the
upper and lower dipstick marks (see photo 3).
If the level is too low severe engine damage
may occur. Oil seal failure may result if the
engine is overfilled by adding too much oil.
If the oil level is checked
immediately after driving the
vehicle, some of the oil will
remain in the upper engine
components, resulting in an inaccurate
reading on the dipstick!
The dipstick is located at the rear of the
engine on the left-hand side (see “Under-
bonnet check points” on page 0•10 for
exact location). Withdraw the dipstick.Using a clean rag or paper towel remove
all oil from the dipstick. Insert the clean
dipstick into the tube as far as it will go,
then withdraw it again.
Note the oil level on the end of the
dipstick which should be between the
upper and lower marks. The “M” mark is
for use when checking the oil level after the
vehicle has been standing overnight; in this
case the oil level should be between the “M”
and upper level markings.Oil is added through the filler cap.
Unscrew the cap and top-up the level; a
funnel may help to reduce spillage. Add
the oil slowly, checking the level on the dipstick
often. Don’t overfill (see “Car care” left).

Warning: DO NOT attempt to
remove the expansion tank
pressure cap when the engine
is hot, as there is a very great
risk of scalding. Do not leave
open containers of coolant
about, as it is poisonous.
Car care
lAdding coolant should not be necessary on
a regular basis. If frequent topping-up is
required, it is likely there is a leak. Check the
radiator, all hoses and joint faces for signs of
staining or wetness, and rectify as necessary.
lIt is important that antifreeze is used in the
cooling system all year round, not just during
the winter months. Don’t top-up with water
alone, as the antifreeze will become too
diluted.
Coolant level
The coolant level should be checked only
with the engine cold. The level is checked
in the expansion tank on the left-hand
side of the engine compartment. Remove the
expansion tank pressure cap and check that
the coolant level is upto the base of filler neck.If topping up is necessary, add a mixture
of water and antifreeze to the expansion
tank until the coolant level is upto the
base of the filler neck. Once the level is
correct, securely refit the pressure cap.12

Power steering
fluid level
Before you start:
4Park the vehicle on level ground.
4Set the steering wheel straight-ahead.
4The engine should be turned off.
Safety first!
lThe need for frequent topping-up indicates
a leak, which should be investigated
immediately.
For the check to be
accurate, the steering must
not be turned once the
engine has been stopped.
Wipe clean the area around the reservoir
cap then remove the cap noting that it
unscrews in a clockwise direction (see
arrow on cap).1Wipe clean the cap dipstick then insert it
fully into the reservoir and withdraw it.2
Note the fluid level on the end of the
dipstick. If the fluid is cold (vehicle not
having been used) the fluid level should
be upto the COLD level marking (1). If the
vehicle has been driven and the fluid is hot
then the fluid level should be upto the upper
(HOT) level marking (2).3If necessary, top-up the reservoir with the
specified type of fluid (note that the type
of fluid differs according to model - see
“Lubricants, fluids and tyre pressures” on
page 0•16). Once the level is correct, securely
refit the reservoir cap. Do not overfill the
reservoir.4
Wiper blades
Check the condition of the wiper blades:
if they are cracked or show signs of
deterioration, or if the glass swept area is
smeared, renew them. For maximum clarity of
vision, wiper blades should be renewed
annually.1To remove a wiper blade, pull the arm
fully away from the screen until it locks.
Swivel the blade then depress the locking
clip at the base of the mounting block and
slide the blade off the arm.2
Warning:
l This check applies only to
vehicles fitted with a separate
power steering system. For
vehicles fitted with power
steering where the fluid
reservoir is part of the power hydraulic
system, this weekly check is not
applicable.
l It is essential to use the correct power
steering fluid, this being dependent on the
year of manufacture and type of system
fitted. A label attached to the fluid
reservoir will indicate the specification of
fluid. However, if necessary refer to the
driver’s handbook supplied with the
vehicle or to your local Jaguar dealer.

Tyre condition and pressure
It is very important that tyres are in good
condition, and at the correct pressure - having
a tyre failure at any speed is highly dangerous.
Tyre wear is influenced by driving style - harsh
braking and acceleration, or fast cornering,
will all produce more rapid tyre wear. As a
general rule, the front tyres wear out faster
than the rears. Interchanging the tyres from
front to rear ("rotating" the tyres) may result in
more even wear. However, if this is
completely effective, you may have the
expense of replacing all four tyres at once!
Remove any nails or stones embedded in the
tread before they penetrate the tyre to cause
deflation. If removal of a nail does reveal thatthe tyre has been punctured, refit the nail so
that its point of penetration is marked. Then
immediately change the wheel, and have the
tyre repaired by a tyre dealer.
Regularly check the tyres for damage in the
form of cuts or bulges, especially in the
sidewalls. Periodically remove the wheels,
and clean any dirt or mud from the inside and
outside surfaces. Examine the wheel rims for
signs of rusting, corrosion or other damage.
Light alloy wheels are easily damaged by
"kerbing" whilst parking; steel wheels may
also become dented or buckled. A new wheel
is very often the only way to overcome severe
damage.New tyres should be balanced when they are
fitted, but it may become necessary to re-
balance them as they wear, or if the balance
weights fitted to the wheel rim should fall off.
Unbalanced tyres will wear more quickly, as
will the steering and suspension components.
Wheel imbalance is normally signified by
vibration, particularly at a certain speed
(typically around 50 mph). If this vibration is
felt only through the steering, then it is likely
that just the front wheels need balancing. If,
however, the vibration is felt through the
whole car, the rear wheels could be out of
balance. Wheel balancing should be carried
out by a tyre dealer or garage.
Tread Depth - visual check
The original tyres have tread wear safety
bands (B), which will appear when the tread
depth reaches approximately 1.6 mm. The
band positions are indicated by a triangular
mark on the tyre sidewall (A).1Tread Depth - manual check
Alternatively, tread wear can be
monitored with a simple, inexpensive device
known as a tread depth indicator gauge.2Tyre Pressure Check
Check the tyre pressures regularly with
the tyres cold. Do not adjust the tyre
pressures immediately after the vehicle has
been used, or an inaccurate setting will result.3
Tyre tread wear patterns
Shoulder Wear
Underinflation (wear on both sides)
Under-inflation will cause overheating of the
tyre, because the tyre will flex too much, and
the tread will not sit correctly on the road
surface. This will cause a loss of grip and
excessive wear, not to mention the danger of
sudden tyre failure due to heat build-up.
Check and adjust pressures
Incorrect wheel camber (wear on one side)
Repair or renew suspension parts
Hard cornering
Reduce speed!
Centre Wear
Overinflation
Over-inflation will cause rapid wear of the
centre part of the tyre tread, coupled with
reduced grip, harsher ride, and the danger of
shock damage occurring in the tyre casing.
Check and adjust pressures
If you sometimes have to inflate your car’s
tyres to the higher pressures specified for
maximum load or sustained high speed, don’t
forget to reduce the pressures to normal
afterwards.
Uneven Wear
Front tyres may wear unevenly as a result of
wheel misalignment. Most tyre dealers and
garages can check and adjust the wheel
alignment (or "tracking") for a modest charge.
Incorrect camber or castor
Repair or renew suspension parts
Malfunctioning suspension
Repair or renew suspension parts
Unbalanced wheel
Balance tyres
Incorrect toe setting
Adjust front wheel alignment
Note: The feathered edge of the tread which
typifies toe wear is best checked by feel.

tyres to increase the ride comfort. This is only allowable if the vehicle is not to be driven at speeds in excess of 100 mph (160 kmh);
if speeds are to exceed this, the tyres must be run at the specified pressures.
Oils perform vital tasks in all engines. The
higher the engine’s performance, the greater
the demand on lubricants to minimise wear as
well as optimise power and economy.
Duckhams tailors lubricants to the highest
technical standards, meeting and exceeding
the demands of all modern engines.
HOW ENGINE OIL WORKS
• Beating friction
Without oil, the surfaces inside your engine
which rub together will heat, fuse and quickly
cause engine seizure. Oil, and its special
additives, forms a molecular barrier between
moving parts, to stop wear and minimise heat
build-up.
• Cooling hot spots
Oil cools parts that the engine’s water-based
coolant cannot reach, bathing the combustion
chamber and pistons, where temperatures
may exceed 1000°C. The oil assists intransferring the heat to the engine cooling
system. Heat in the oil is also lost by air flow
over the sump, and via any auxiliary oil cooler.
• Cleaning the inner engine
Oil washes away combustion by-products
(mainly carbon) on pistons and cylinders,
transporting them to the oil filter, and holding
the smallest particles in suspension until they
are flushed out by an oil change. Duckhams
oils undergo extensive tests in the laboratory,
and on the road.
Engine oil types
Mineral oilsare the “traditional” oils,
generally suited to older engines and cars not
used in harsh conditions. Duckhams
Hypergrade Plus and Hypergradeare well
suited for use in most popular family cars.
Diesel oilssuch as Duckhams Dieselare
specially formulated for Diesel engines,
including turbocharged models and 4x4s.
Synthetic oilsare the state-of-the-art in
lubricants, offering ultimate protection, but at
a fairly high price. One such is Duckhams QS,
for use in ultra-high performance engines.
Semi-synthetic oilsoffer high performance
engine protection, but at less cost than full
synthetic oils. Duckhams QXRis an ideal choice
for hot hatches and hard-driven cars.
