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.

Fuel and refuelling

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.

DIESEL MISFUELLING PROTECTION
DEVICE
Diesel engine vehicles in some markets are
equipped with a misfuelling protection device,
incorporated into the fuel filler neck, designed
to alert that the wrong fuel type has been
selected. If the narrow filler nozzle fitted to
pumps delivering unleaded petrol is correctly
inserted (i.e. fully inserted) into the filler neck,
the misfuel protection de vice will activate.
The protection device c ontinually interrupts the
fuel flow from the pump, until the protector
mechanism in the filler neck is reset.
When activated, the yellow protection device
will be visible in the f iller neck. The device will
need to be reset before the tank can be
correctly filled with dies el fuel. This is achieved
using the reset tool, lo cated in the luggage
compartment, clipped onto the battery
restraining bar.
Note: It is the driver’s responsibility to fill the
vehicle with the correct fuel. The diesel
misfuelling protection devi ce only reduces the
risk of filling the vehicle with the incorrect fuel.
Note: When refuelling the vehicle using a
disposable fuel canister, use a canister
designed for diesel fuel where possible. The
spout on petrol canist ers may activate the
protection device. The device may also be
activated by fuel pumps with a smaller nozzle
than those fitted to standard diesel pumps.
Resetting the protection device
To reset the misfuelling protection device:
1. Insert the reset tool (with the teeth
uppermost) into the fi ller neck opening, as
far as it will go. The triangular section on
the reset tool stop s on the protection
device at the requi red insertion depth.
2. Pivot the reset tool handle downwards to
engage the teeth into the protection device.
3. Keeping the reset tool handle held down,
slowly pull the reset tool out of the filler
neck to reset the misfuelling protection
device.
Note: To ensure that the pr otection device is
correctly reset, check that the yellow protector
is no longer visible in the filler neck.
After resetting the misfuelling protection
device, remove the tool fr om the filler neck and
secure it to the battery restraining bar. If
subsequent driveability difficulties are
encountered, seek assistance from your
Dealer/Authorised Repairer.
WARNINGS
When the misfuelling protection
device is activated, it could cause fuel
to be discharged from the filler neck.
CAUTIONS
Using the incorrect fuel can result in
major damage to your vehicle’s engine
and fuel system.

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

Towing

RECOMMENDED TOWING WEIGHTS
Nose/tongue weight must be the greater of
50 kg (110 lbs) or 7% of the actual trailer
weight, up to the maximum tow hitch load.
Nose/tongue weight can be measured using a
proprietary brand of nose weight indicator.
If it is necessary to increase the nose/tongue
weight up to the maximu m allowed, the vehicle
load should be reduced accordingly. This
ensures that the Gross Vehicle Weight (GVW),
and maximum rear axle load, are not exceeded.
Note: When towing the maximum permissible
gross vehicle weight can be increased by a
maximum of 100 kg (220 lb.) provided that the
road speed is limited to 100 km/h (60 mph).
Note: When calculating rear axle loading,
remember that the trailer nose/tongue weight,
the load in the vehicle's luggage area and the
weight of rear seat pa ssengers must all be
added together.
Towing weights - Australia only
The weight of a traile r must not exceed 1.5
times the towing vehicle’s weight. The
nose/tongue weight must be a minimum of 7%
of gross caravan/trai ler weight, up to a
maximum of 350 kg (722 lbs).
ESSENTIAL TOWING CHECKS
• The trailer should be parallel to the ground
when loaded and connected to the vehicle.
• When calculating the laden weight of the
trailer remember to include the weight of
the trailer, plus the weight of the load.
• If the load can be divided between the
vehicle and trailer, loading more weight
into the vehicle will generally improve
stability. Do not exceed the vehicle's
weight limits. See WEIGHTS (page 259).
• Ensure that all applic able regulations and
legislation are complied with when loading
and towing a trailer.
• Increase rear tyre pressures of the towing
vehicle to those for maximum vehicle
loading conditions.
• Ensure trailer tyre pressures are set to
trailer manufacturer' s recommendations.
• If the vehicle is loaded to maximum Gross
Vehicle Weight (GVW) the nose weight is
limited (see Towi ng weights table).
• Ensure that a suitable breakaway cable or
secondary coupling is used. Refer to the
trailer manufacturer' s instructions for
guidance.
• Ensure that the tow ball is secure.
• Check the operation of all trailer lights.
Maximum permissible
towing weights
Unbraked trailers 750 kg (1653 lb.) Trailers with
overrun brakes 1850 kg (4080 lb.)
Nose/Tongue weight 75 kg (165 lb.)
WARNING
Do not exceed the Gross Vehicle
Weight (GVW), m aximum rear axle
weight, maximum trailer weight, or
nose/tongue weight. Exceeding any of these
limits could cause inst ability and loss of
control. See WEIGHTS (page 259).
WARNING
Do not loop the breakaway cable over
the tow ball as it may slide off.

Vehicle care
188

Do not use household soaps or detergents. The
use of Jaguar Vehicle Shampoo is
recommended.
Note: The vehicle's brightwork should be
cleaned using a sponge and generous
quantities of cold or lukewarm water only.

button to start the engine.
6. Select D (Drive) using the JaguarDrive
selector and drive away.
Do not start the engine or change the
JaguarDrive selector position during the car
wash.
After leaving the car wash, switch on the
windscreen wiper immediately to remove water
and prevent a build up of wax.
Underbonnet cleaning
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.

Maintenance
192

GENERAL INFORMATION
Regular systematic maintenance is the key to
ensuring the continued reliability and efficiency
of your vehicle.
Maintenance is the owner's responsibility and
you must ensure that owner maintenance
operations, oil services, inspections and brake
fluid and coolant changes are carried out when
required and according to the manufacturer's
recommendations.
The routine maintenance requirements for your
vehicle are shown in th e Service Portfolio book.
Most of this necessar y workshop maintenance
requires specialised knowledge and
equipment, and should preferably be entrusted
to a Dealer/Authorised Repairer.
Service Portfolio
The Service Portfolio book includes a Service
Record section, which enables a record to be
kept of all the servicing and inspections that are
carried out on the vehicle. This section of the
book also has an area for brake fluid changes
to be recorded.
Ensure your service provider signs and stamps
the book after each se rvice and inspection.
Owner maintenance
In addition to the routine services and
inspections, a number of simple checks must
be carried out more frequently. These checks
can be carried out by th e owner and advice is
given on the pages that follow.
Daily checks
• Operation of lamps, horn, direction
indicators, wipers, washers and warning
indicators.
• Operation of seat belts and brakes.
• Look for fluid deposits underneath the
vehicle that might indicate a leak.
Condensation drips from the air
conditioning is normal.
CAUTION
Severe damage to the electrical system
and electronic components can occur, if
any attempt is made to diagnose faults in the
electrical system using conventional
diagnostic equipment (e .g. the use of test
lamps or low impedanc e voltmeters). The
fitting of any electric al accessory should only
be entrusted to a Deal er/Authorised Repairer.CAUTION
Any significant or sudden drop in fluid
levels, or uneven tyre wear, should be
reported to a qualifie d technician without
delay.
