Fuel and refuelling

FUEL CONSUMPTION
The fuel consumption figures shown below have been calculated using a standard testing
procedure (the new EC test proc edure from Directive 99/100/EC), and produced in accordance with
The Passenger Car Fuel Cons umption (Amendment) Order 1996.
Under normal use, a vehicle's actu al fuel consumption figures may differ from those achieved
through the test procedure, de pending on driving technique, ro ad and traffic conditions,
environmental factors, ve hicle load and condition.
Urban cycle
The urban test cycle is carried out from a cold start and cons ists of a series of accelerations,
decelerations and periods of stea dy speed driving and engine idling. The maximum speed attained
during the test is 50 km/h (30 mph) with an average speed of 19 km/h (12 mph).
Extra-urban cycle
The extra-urban test cycle is carried out immediatel y after the urban test. Approximately half of the
test comprises steady-speed driving, while the re mainder consists of a series of accelerations,
decelerations and engine idling . The maximum test speed is 120 km/h (75 mph) and the average
speed 63 km/h (39 mph). The test is carried out over a distance of 7 km (4.3 miles).
Combined
The combined figure is an average of the urban an d extra-urban test cycle results, which has been
weighted to take account of the differ ent distances covered during the two tests.

Certification Agency (VCA) website at http://www.vcacarfueldata.org.uk/.

CAUTIONS
Commercially operated automatic car
washes, jet washes and power-operated
mops, are not recommen ded. The detergents
used can contain certain chemicals which
may, over time, be detrimental to some
exterior parts of the vehicle. Prolonged usage
of automatic car wash es and power-operated
mops will also cause fine scratches in the paint
surface.
Ensure that Auto wipe is not selected
when entering a car wash, or damage to
the wiper blades and arms can occur if they
operate during the wash cycle.
Ensure that when using an automatic
drive through car wash, N (Neutral) is
selected and that the ignition is left in
convenience mode for the duration of the
wash.
CAUTIONS
Do not use a high pr essure washer or
steam cleaner in the engine
compartment. Damage to components could
occur.
Ensure that the brake fluid reservoir is
kept dry at all times. Only use a clean,
dry cloth to clean the brake fluid cap and
reservoir.

Safety in the garageFuel system
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, 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 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).

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
