SAFETY PRECAUTIONS

FUEL QUALITY

Gasoline engined vehicles

WARNINGS

Petroleum gasses are highly
flammable, have a low flash point
and are explosive, especially in

confined spaces. Avoid exposing the
gasses to any potential sources of
ignition as the resulting fire and
explosion may cause serious injuries
and/or death.

Only use containers specifically
designed for carrying fuel, and
alway remove them from the

vehicle to fill them. Failure to do so may
result in spillage and cause a fire.

Switch off the engine when
refuelling, as it is both a source of
extreme temperatures, and

electrical sparks. The resulting fire and
explosion may cause serious injury and
death.

Switch off any personal electronic
devices such as mobile phones,
or music players. They have the

potential to cause electrical sparks. The
resulting fire and explosion may cause
serious injury and death.

Do not smoke, use a naked flame,
or cause sparks. The resulting fire
and explosion may cause serious

injury and death.

Do not overfill the fuel tank.
Overfilling may cause spillage
when the vehicle is driven.

Spillage may also occur if the fuel
expands in high ambient temperatures.

The presence of any unusual
fumes (for example, gasoline or
exhaust fumes) in the passenger

compartment and or luggage
compartment should be corrected
immediately by a Jaguar Dealer. If you
must drive under these conditions do so
only with all windows fully open.

Any modifications to the fuel
system not specifically designed
for this Jaguar are prohibited.

Such modifications in some
circumstances could result in a fire. All
service actions should be entrusted to a
Jaguar Dealer.

CAUTION

Catalytic Converter - Do not
continue to operate the vehicle if
any engine malfunction is evident.

Misfire, loss of engine performance,
excessive oil consumption or engine
run-on may lead to unusually high
catalytic converter temperatures and
may result in damage.

CAUTIONS

Do not use leaded fuels, lead
substitutes, or fuel additives. Doing
so can cause damage to the

engine, fuel, and emission control
systems.

Only use high quality gasoline, as
using lower quality fuels can cause
damage to the engine, fuel, and

emission control systems.

WARNINGS

Fuel and refuelling

192

L

Unleaded fuel

Unleaded fuel must be used for the
emission control system to operate
properly. Its use will also reduce spark
plug fouling, exhaust system corrosion
and engine oil deterioration.

Use only unleaded gasoline with a
minimum anti-knock index (AKI) of 91.
Using unleaded fuel with a lower AKI than
recommended can cause persistent
heavy spark knock ( a metallic rapping
noise). If severe, this can lead to engine
damage.

If a heavy spark knock is detected even
when using fuel to the recommended
octane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, consult a Jaguar Dealer to
have the problem corrected. Failure to do
so is misuse of the vehicle, for which
Jaguar Cars is not responsible. However,
occasional light spark knock for a short
time while accelerating or driving up hill,
may occur.

Alternative fuels

Fuels containing alcohol

Some fuel suppliers sell fuel containing
alcohol without advertising its presence.
Where uncertainty exists check with the
service station operator.

Note: Some difficulty in starting may be
encountered when using alcohol blended
fuel.

Ethanol

Fuels containing up to 10% Ethanol (grain
alcohol) may be used. Ensure that the fuel
has octane ratings no lower than those
recommended for unleaded fuel. Most
drivers will not notice any operating
difference with fuel containing Ethanol. If
a difference is detected, the use of
conventional unleaded fuel should be
resumed.

Fuel system cleaning agents
should not be used, unless
approved by Jaguar Cars.

Unapproved products may be harmful to
fuel system components on your vehicle.

CAUTIONS

CAUTION

Fuel containing alcohol can cause
paint damage, which may not be
covered under the warranty.

CAUTIONS

This vehicle is not suitable for use
with fuels containing more than
10% Ethanol.

Do not use E85 fuels (85% Ethanol
content). Equipment necessary for
the use of fuels containing more

than 10% Ethanol is not fitted to this
vehicle. If E85 fuels are used, serious
engine and fuels system damage will
occur.

193

Fuel and refuelling

R

Methanol

Some fuels contain Methanol (Methyl or
wood alcohol). If you use fuels containing
Methanol the fuels must also contain
co-solvents and corrosion inhibitors for
Methanol. Also, do not use fuels which
contain more than 3% Methanol even if
they contain co-solvents and corrosion
inhibitors. Fuel system damage or vehicle
performance problems resulting from the
use of such fuels is not the responsibility
of Jaguar Cars, and may not be covered
under the warranty.

Methyl Tertiary Butyl Ether (MTBE)

Unleaded fuel containing an oxygenate
known as MTBE can be used provided
that the ratio of MTBE to conventional
fuel does not exceed 15%. MTBE is an
Ether based compound derived from
Petroleum, which has been specified by
several refiners as the substance to
enhance the Octane rating of fuel.

Reformulated gasoline

Several petroleum companies have
announced the availability of
reformulated fuels. These fuels are
specially formulated to further reduce
vehicle emissions. Jaguar Cars fully
supports all efforts to protect and
maintain ambient air quality, and
encourages the use of reformulated
gasoline where available.

RUNNING OUT OF FUEL

Note: If the vehicle does run out of fuel, a
minimum of 4 litres (0.8 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.

FUEL FILLER FLAP

CAUTIONS

Avoid running out of fuel. Doing so
can cause damage to the vehicle's
engine, fuel, and emission control

systems.

Do not run the fuel tank dry.
Running the fuel tank dry could
create an engine misfire.

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 filler

flap. Failure to do so may result in injury
or death.

Fuel and refuelling

194

L

The fuel filler flap release switch is
located in the knee bolster switchpack
below the facia. The switch is inhibited if
the vehicle is armed. The filler flap is on
the right-hand side of the vehicle.

A label on the inside of the fuel filler flap
serves as a reminder to fill the tank with
the correct fuel.

REFUELLING

Fuel filling

Gas station pumps are equipped with
automatic cut-off sensing to avoid fuel
spillage. Fill the tank slowly until the filler
nozzle automatically cuts-off the supply.
Do not attempt to fill the tank beyond this
point.

To remove the filler cap, turn it
counterclockwise approximately a ¼
turn, until a slight resistance is met.
Continue turning to release it. Remove
the cap from the filler neck.

The cap is held by a retaining strap and
can be stowed on the filler flap hook.

WARNINGS

Do not fully remove the fuel filler
cap until any captive tank
pressure has been released (wait

until the hissing stops).

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.

CAUTIONS

Ensure that you 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 fuel system damage.

If the vehicle is filled with incorrect
fuel it is essential that you seek
qualified assistance before you

start the engine. Running the engine can
cause serious engine and fuel system
damage.
