Fuel

PETROL ENGINES
USE ONLY RECOMMENDED FUEL
4 cylinder engines:
Use 90 RON minimum leaded or unleaded fuel
wherever possible.
V8 engines:
Use 91 - 93 leaded or unleaded fuel wherever
possible.
The RON value (octane rating) of petroleum
commonly available at garage forecourts will
vary in different countries. The RON value
quoted is the MINIMUM requirement and
whilst this can be safely exceeded, no
advantage in performance or fuel economy
will be gained by using a higher octane fuel.
If heavy engine knock is detected when using
the recommended octane rated fuel, or if
steady engine knocking is present while
maintaining a steady speed on level roads,
contact your dealer for advice.
NOTE: An occasional, light, engine knock
while accelerating or climbing hills is
acceptable.
DIESEL ENGINES
The quality of diesel fuel (Derv) can vary in
different countries and only clean, good
quality fuel should be used. It is important
that the sulphur content of diesel fuel does
not exceed 1%; in Europe all supplies should
be within this limit, but in other parts of the
world, you should check with your supplier.
Ensure the fuel filter element is changed and
the fuel sedimenter drained, at the
recommended service intervals.
If good quality diesel fuel is unavailable and it
is necessary to use poor quality fuel, it may be
necessary to have the fuel filter/sedimenter
drained regularly.
NOTE: The use of paraffin (kerosene) as a
diesel fuel additive is illegal in the UK.
WARNING
On both petrol and diesel engine vehicles, if
the fuel tank is accidentally filled with the
wrong fuel, it is ESSENTIAL that you contact
your dealer BEFORE attempting to start the
engine!

Fuel filling
To unlock the fuel cap;
1. Insert the key and turn it 90° clockwise.
2. Turn the key back to the vertical and then
remove.
The cap should then be unscrewed gradually
(see Warning below).
WARNING
To avoid any sudden discharge of fuel
caused by excessive air pressure, the cap is
designed to allow the fuel tank to vent
during the first half turn. DO NOT fully
remove the cap until pressure has been
released.
Filling station pumps are equipped with
automatic cut-off sensing to avoid fuel
spillage - only fill the tank until the filler nozzle
automatically shuts off. DO NOT attempt to fill
the tank beyond this point or spillage could
result due to expansion of the fuel.
WARNING
DO NOT fully fill the tank if the vehicle is to
be parked on a slope in direct sunlight or
high ambient temperature - expansion of the
fuel could cause spillage.
When replacing the fuel cap, turn it clockwise
until the cap clicks at least three times - this
locks the cap (the key is not needed).
SAFETY ON THE FORECOURT
Petroleum gases are highly inflammable
and in confined spaces are also explosive.
Always take sensible precautions when
refuelling:
• Switch off the engine.
• Do not smoke or use a naked flame
or light.
• Take care not to spill fuel.
• Do not overfill the tank.

Empty fuel tank
DO NOT RUN THE FUEL TANK DRY!
In the case of Tdi diesel models, qualified
assistance may be required to prime the fuel
system before the engine can be restarted.
Td5 diesel engine vehicles
In the case of Td5 vehicles,carry out the
following procedure:
1. Turn off the starter switch and wait for 15
seconds.
2. Turn the starter key to position ’II’ and
wait for 30 seconds.
3. Turn off the starter switch.
Repeat steps 2 and 3 six times.
4. Fully depress the accelerator pedal.
5. Keeping the pedal depressed, start
cranking the engine.
6. Continue cranking the engine and as soon
as the engine is running on all cylinders,
ease the accelerator pedal back to
approximately halfway through its travel,
and release the starter key. The engine
should now be running.
7. If the engine fails to start, repeat the
process.
During the above procedure, the fuel pump
will be heard to operate (priming the engine).
This noise is not a cause for concern.
IMPORTANT INFORMATION
The engine must NOT be cranked for
more than 20 seconds in any one period.
If the above procedure is carried out on a
vehicle that has NOT run out of fuel, it will
result in the engine flooding with fuel and
failing to start.

FUEL CUT-OFF SWITCH
(Td5 models only)
The fuel cut-off switch is a safety device
which, in the event of a collision or sudden
impact, automatically cuts off the fuel supply
to the engine.
The switch is located on the engine
compartment bulkhead. After an impact, the
switch must be reset by pressing the rubber
top (arrowed in illustration) before the engine
can be restarted.
WARNING
ALWAYS check for fuel leaks before
resetting the switch!
