Fuel and refuelling

Sulphur content
In some countries diesel may contain higher
levers of Sulphur, wh ich could cause damage
to the vehicle, if in doubt contact a local
Dealer/Authorised Repairer for advice.
RUNNING OUT OF FUEL
Note: If the vehicle does run out of fuel, a
minimum of 4 litres (0.9 gallons) will be
required to restart the engine. The vehicle will
need to be driven 1.6-5 km (1-3 miles) in order
to reset the engine management and
monitoring systems.
Note: If the vehicle does run out of fuel,
seeking qualified assistance is advisable.
Diesel engines
Vehicles with diesel e ngines are equipped with
a system to prevent the fuel tank from
emptying completely. When the fuel reaches a
minimum level, the system will activate a
reduced power mode (i.e . the engine will not
run properly). This will be followed by the
engine stopping in a pproximately 1.6 km
(1 mile). This feature prevents the fuel system from
running dry, which could cause damage to the
vehicle. If the gauge indicates low fuel or the
warning indicator illumi
nates, the fuel tank
should be refuelled as soon as possible at the
next filling stat ion, with at least 4 litres (0.9
gallons) of fuel.
If the system protection function has activated,
the vehicle must firstly be refuelled, then
restarted using the following procedure:
1. With the brake pedal pressed, press and
hold the engine START/STOP button and
crank the engine for five seconds.
2. Release the START/STOP button.
3. With the brake pedal pressed, press and
release the START/STOP button to crank
the engine. The engine should start within
approximately five seconds.
Note: If the engine does not start, pause for ten
seconds with the ignition in convenience
mode, before re peating the procedure from the
beginning.
FUEL CUT-OFF
The fuel system cut-off forms part of the
Supplementary Restraint System (SRS) fitted
to your vehicle. Following an impact, and
depending on the severity , the fuel pump may
be switched off.
CAUTION
Your vehicle is fitted with a Diesel
Particulate Filter (DPF), the maximum
Sulphur content must not exceed 0.005%.
Using an incorrect fuel will cause serious
damage to the DPF. See DIESEL
PARTICULATE FILTER (DPF) (page 135).
CAUTION
Avoid running out of fuel. Doing so can
cause damage to th e vehicle's engine,
fuel and emission control systems.
CAUTION
Do not crank the engine for longer than
30 seconds, or damage to the fuel pump
may occur.

Resetting the fuel cut-off
1.Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thor oughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualified advice and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
FUEL FILLER FLAP
Note: The fuel filler flap cannot be opened
when the alarm system is armed.
The fuel filler flap is located on the right-hand
side of the vehicle, at the rear.
1. Ensure that the vehicle is fully unlocked.
Push and release the rear of the flap (in the
area indicated in the illustration) to
unlatch.
2. Pull the fuel filler flap open. The label on
the inside of the flap indicates the correct
fuel for the vehicle. 3.
Twist the cap counte r-clockwise to undo.
4. Stow the cap on the lip provided on the top
of the hinge arm, as shown.
When replacing the cap, turn it clockwise until
the ratchet clicks. Failur e to do so could cause
the Engine malfunction warning indicator to
illuminate.
To close the filler flap, pus h the flap closed until
it latches.
WARNING
The fuel cut-off should never be reset
if you can smell fuel, or a leak can be
seen. Doing so can lead to a fire
which may cause persona l injury or death.
WARNINGS
Open the fuel filler cap slowly and
allow the pressure to release before
fully removing the cap to avoid fuel
spillage due to rapid expansion.
Take note of all warnings and
instructions given on the label affixed
to the inside of the fi ller flap. Failure to
do so may result in injury or death.

REFUELLING
Fuel filler
Filling station pumps used for diesel
commercial vehicles deliver fuel at a higher
rate than normal. The hi gher fill rate can cause
premature cut-off and ma y cause fuel spillage.
Therefore, it is recommended that only
standard light vehicle pumps are used. If the fuel cuts off as soon as the trigger on the
pump is operated, check that the correct fuel
has been selected. Immediate cut-off may have
been caused by the fuel guard system.
See
DIESEL MISFUELLING PROTECTION
DEVICE (page 180).
Fuel tank capacity
Avoid the risk of running out of fuel and never
intentionally drive the vehicle when the fuel
gauge indicates that the tank is empty. When
refuelling your vehicle after the fuel gauge
reads empty, you may not be able to add the
fuel quantity shown below, as there will be a
small reserve remaining in the tank.
All engines
WARNINGS
When refuelling ensure that all
windows, doors, and sunroof are fully
closed, particularly if young children
or animals are in the vehicle. Fuel vapour
contains harmful chemical compounds, some
of which may cause cancer.
Do not attempt to fill the tank to its
maximum capacity. If the vehicle is to
be parked on a slope, in direct
sunlight or high ambient temperature,
expansion of the fuel could cause spillage.
Filling station pumps are equipped with
automatic cut-off sensing, to avoid fuel
spillage. Fill the tank unt il the filler nozzle
automatically cuts off supply. Do not attempt
to fill the tank beyond this point.
CAUTIONS
Check the fuel pump information
carefully, to ensure that you are putting
the correct fuel into the vehicle. Filling a
vehicle with the incorrect fuel can cause
serious engine and fu el system damage.
It is the driver’s responsibility to fill the
vehicle with the correct fuel. If the
vehicle is filled with the wrong type of fuel, do
not start the engine. Call for Roadside
Assistance.

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.
For additional information on fuel consumption figures and exhaust emissions, visit the Vehicle
Certification Agency (VCA) website at http://www.vcacarfueldata.org.uk/.

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).
