SAFETY PRECAUTIONS

!

WARNING:

• Fuel vapour is highly flammable,

and in confined spaces is explosive
and toxic. In the event of
inadvertent spillage, and before
refuelling, always switch OFF the
engine. Do not use exposed flame
or light. Do not smoke. Do not
inhale fumes.

• Do not fill the tank so that fuel is

visible in the fuel filler intake tube.
This could cause spillage and
danger from exposed fuel.

• The presence of any unusual fumes

(for example, petrol or exhaust
fumes) in the passenger
compartment and or luggage
compartment should be corrected
immediately by a Jaguar Retailer. 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 vehicle are prohibited. Such
modifications in some
circumstances could result in a fire.
All service actions should be
entrusted to a Jaguar Retailer

• Do not operate a cell phone at a gas

station.

Caution: Do not put additives of any
kind (fuel or oil) in the fuel tank.
Additives could reduce engine life or
affect exhaust emissions.

FUEL TANK FILLING

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

To remove the filler cap, turn it
counter-clockwise approximately a ¼
turn, until a slight resistance is met,
continue turning to release it. Remove the
cap from the filler neck.

Fuel and Refuelling

L

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

The cap, which is held by a retaining
strap, can be stowed on the hook on the
flap to allow easy access to fill the tank.

When filling, the dispenser nozzle must be
inserted into the filler neck sufficiently to
open the trap door for fuel to flow into the
fuel tank. For quickness and to
completely fill the tank, make sure that the
fuel nozzle rests on the bottom of the filler
neck, as shown. Fill the tank until the filler
nozzle automatically shuts off. Filling
beyond this point could result in fuel
spillage.

After refuelling, refit the filler cap in the
filler neck and twist the cap clockwise
until it clicks three times. Close the flap,
which automatically locks shut.

The continuous use of high quality fuel
makes the need for additional additives
unnecessary. This will help to protect the
engine components against corrosion,
carbon deposit formation and prevent the
fuel injection system from clogging.

If in doubt your local Jaguar Dealer will
advise on which fuel must be used in your
vehicle.

Emission control components

Owing to the legislative requirements or
options available in some countries, a
Jaguar Dealer should be consulted where
any doubt exists as to the precise
emission control system specification of
this vehicle.

FUEL CAPACITY

Avoid the risk of running out of fuel and
never intentionally drive the car 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.

FUEL REQUIREMENTS –
GASOLINE ENGINES

The filler neck of the fuel tank is a small
diameter to suit the unleaded fuel pump
nozzle and will prevent the larger diameter
leaded fuel nozzle from entering the filler
neck.

Caution: Vehicles with gasoline
engines must only be filled with
Unleaded Fuel. Leaded fuel will
damage the catalytic converters.

Unleaded fuel

All vehicles are fitted with a catalytic
system and can only use 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 Premium unleaded gasoline with
a minimum anti-knock index (AKI) of 91.

Fuel and Refuelling

R

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 of 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 Limited, is not responsible.
However, occasional light spark knock for
a short time while accelerating or driving
up hill, may occur.

Fuels containing alcohol

Caution: Take care not to spill fuel
during refuelling. Fuel containing
alcohol can cause paint damage, which
may not be covered under the
warranty.

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

Caution: This vehicle is not suitable for
use with fuels containing more than 10
per cent ethanol. Do not use E85 fuels
(85 per cent ethanol content).
Equipment necessary for the use of
fuels containing more than 10 per cent
is not fitted to this vehicle. If E85 fuels
are used, serious engine and fuel
system damage will occur.

Fuels containing up to 10% ethanol (grain
alcohol) may be used. Make sure 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.

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 that
contain more than three per cent
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 Limited, 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
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 designed
to further reduce vehicle emissions.
