Weekly checks
•Engine oil level (non- electronic dipstick
vehicles). See ENGINE OIL CHECK - V6
Petrol engines (page 197).
• Engine coolant check. See ENGINE
COOLANT CHECK (page 204).
• Brake fluid level. See BRAKE FLUID
CHECK (page 206).
• Power steering fluid level. See POWER
STEERING FLUID CHECK (page 208).
• Screen washer fluid level. See WASHER
FLUID CHECK (page 209).
• Tyre pressures and condition. See TYRE
CARE (page 217).
• Operate air conditioning. See AUTOMATIC
CLIMATE CONTROL (page 116).
Note: The engine oil level on V6 petrol engines,
should be checked more frequently if the
vehicle is driven for prolonged periods at high
speeds. The engine oil level on diesel and V8
petrol engines is checked automatically at all
times by the electronic dipstick.
Severe driving conditions
When a vehicle is operated in severe
conditions, more frequent attention must be
paid to servicing requirements.
Severe driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading. •
Driving in extremely hot or cold
conditions.
• Driving in areas using road salt or other
corrosive materials.
• Towing a trailer or driving in mountainous
conditions.
Contact your Dealer/Authorised Repairer for
advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporati ve control equipment,
designed to meet specific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissi ons, engine performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes, it is essential that any dynamometer
testing is carried out only by a qualified person,
familiar with the dynamometer testing and
safety procedures practised by
Dealers/Authorised Repairers.
CAUTION
Ensure that you take notice of any
message centre information and
warnings relating to engi ne oil level (V8 petrol
and diesel engines only). Top-up the level
when advised to do so. See ENGINE OIL
CHECK - V8 Petrol engines (page 199).

battery acid, antifreeze, brake, clutch and
power steering fluid, petrol, diesel, 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. Use authorised
waste disposal site s to dispose of
used oil and toxic chemicals.
WARNINGS
If the vehicle has been driven
recently, do not touch exhaust and
cooling system components until the
engine has cooled.
Never leave the engi ne 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.
Keep your hands and clothing away
from drive belts, pulleys and fans.
Some fans may continue to operate
after the engi ne has stopped.
Remove metal wrist bands and
jewellery, before working in the
engine compartment.
Do not touch electrical leads or
components while the engine is
running, or with the starter switch
turned on.
Do not allow tools or metal parts of
the vehicle to make contact with the
battery leads or terminals.WARNINGS
Under no circumstances should any
part of the fuel system be dismantled
or replaced by anyone other than a
suitably qualified vehicle technician. Failure to
comply with this instruct ion, may result in fuel
spillage with a consequent serious risk of fire.
Ensure sparks and naked lights are
kept away from the engine
compartment.
Wear protective cl othing, including,
where practicable, gloves made from
an impervious material.

The oil consumption of an engine is influenced
by many factors. Unde r high loads an engine
will consume more oil than usual. Diesel
engines consume slightly more oil than petrol
engines.
Above normal oil consumption should be
expected when the engine is new.
Check the oil level weekly , when the engine is
cold and with the vehicle resting on level
ground.

CAUTIONS
If the message ENGINE OIL PRESSURE
LOW is displayed, st op the engine as
soon as it is safe to do so and seek qualified
assistance. Do not start the engine until the
cause has been identified and rectified.
Your vehicle’s warranty may be
invalidated if damage is caused by the
use of improper engine oil. Low quality or
obsolete oils do not pr ovide the protection
required by modern, high performance
engines. Failure to use an oil that meets the
required specification could cause excessive
engine wear, a build up of sludge and deposits
and increased pollution. It could also lead to
engine failure.
Do not use oil additi ves of any type as
engine damage coul d occur. Use only
specified lubricants.

Checking the oil level
Note: If it is necessary to check the oil level
when the engine is hot, switch off the engine
and let stand for five minutes to allow the oil to
drain into the sump. Do not start the engine.
1. Withdraw the dipstick ( 1) and wipe the
blade clean with a lint free cloth.
2. Fully re-insert the di pstick and withdraw
again to check the oil level. Never allow the
oil level to fall below the lower mark or
notch on the dipstick.
As a general guide, if the level on the dipstick:
• Is nearer to the upper mark or notch than
the lower, add no oil.
• Is nearer to the lower mark or notch than
the upper, add half a litre (one pint) of oil.
• Is below the lower mark or notch, add one
litre (two pints) of oi l and re-check the level
after a further five minutes.
Topping up the oil
1. Unscrew the oil filler cap ( 2).
2. Add oil to maintain the level between the
MIN and MAX marks or notches on the
dipstick. Clean up any oil spilled during
topping-up.
3. Check the oil level again after 5 minutes.
It is essential to use the correct specification
oil, and to ensure it is suitable for the climatic
conditions in which the vehicle is to be
operated.
Note: The approximate quant ity of oil required
to raise the level from MIN to MAX on the
dipstick is 1.0 litre (1.76 pints).

CAUTIONS
Your vehicle warranty may be
invalidated if damage is caused by using
oil that does not meet the required
specification.
Failure to use an oil that meets the
required specificat ion could cause
excessive engine wear, a build up of sludge
and deposits, and increa se pollution. It could
also lead to engine failure.
Overfilling with oil c ould result in severe
engine damage. Oil should be added in
small quantities and the level re-checked to
ensure that the engine is not overfilled.

ENGINE OIL CHECK - V8 Petrol
engines
Engine oil consumption
A certain amount of oil consumption is normal.
The rate of consumpt ion will depend on the
following:
• The quality and viscosity of the oil.
• Climatic conditions.
• The speed at which th e engine is being
operated.
• Road conditions.
Drivers should expe ct above normal
consumption when th e engine is new.
Checking the oil level
For an accurate oil level reading to be taken, the
following conditions must be met:
•The vehicle needs to be parked on level
ground. •
The oil level should be checked when the
oil is hot. It is therefore recommended that
a reading is taken after a journey.
• The vehicle needs to stand for
approximately 10 minutes after the engine
is switched off, to allow the oil to drain
back into the sump.
Note: The system will not gi ve a reading until
the oil level has stabilised.
Once the above conditions are met, check the
oil level as follows:
1. Switch on the ignition - do not start the
engine.
2. Set the transmission to Park ( P).
3. Press the TRIP butt on on the end of the
left-hand column stalk repeatedly, until the
oil can icon is displa yed at the bottom of
the message centre.
4. The oil level and topping- up advice will be
shown in the message centre. Top-up as
instructed.
CAUTIONS
It is recommended that the oil level is
checked weekly. If any significant or
sudden drop in oil level is noted you should
seek qualified assistance immediately.
Your vehicle’s warranty may be
invalidated if damage is caused by the
use of improper engine oil. Low quality or
obsolete oils do not provide the protection
required by modern, high performance
engines. Failure to use an oil that meets the
required specification could cause excessive
engine wear, a build up of sludge and deposits
and increased pollution. It could also lead to
engine failure.
Do not use oil additi ves of any type as
engine damage could occur. Use only
specified lubricants.
