Fuel and refuellingSAFETY PRECAUTIONS
Avoid exposing the f uel gasses to any
potential sources of ignition as the
resulting fire and explosion may
cause serious injuries and/or death.
Switch off the engine when refuelling,
as it is both a source of extreme
temperatures, and electrical sparks.
Switch off any personal electronic
devices such as mobile phones, or
music players.
PETROL ENGINED VEHICLES
Do not use leaded fuels, lead
substitutes or fuel additives.
Fuel system cleaning agents should not
be used, unless a pproved by Jaguar.
OCTANE RATING
The minimum octane rating for fuel used is 95
RON (Research Octane Number). The vehicle
will run on lower ratings, but it may cause
pronounced engine knock or pinking. If the
pinking is severe it ca n cause damage to the
engine, fuel and emis sion control systems.
Note: Occasional, light, engine knock
experienced while accele rating or climbing hills
is acceptable.
Super Green Plus 98 RON unleaded fuel (where
available) may be used as an alternative to the
standard 95 RON unleaded fuel.
Some countries have only 91 RON fuel
available. Vehicles sold in these countries are
specially calibrated to use this fuel.
ETHANOL
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
fuel system damage will occur.
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 opera ting difference with
fuel containing ethanol. If a difference is
detected, the use of co nventional unleaded fuel
should be resumed.
METHANOL
Wherever possible avoid using fuel
containing 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 fo r methanol. Also, do not
use fuels which contain more than 10%
methanol even if they contain co-solvents and
corrosion inhibitors. Fu el system damage or
vehicle performance pr oblems resulting from
the use of such fuels is not the responsibility of
Jaguar, and may not be covered under the
warranty.

METHYL TERTIARY BUTYL ETHER
(MTBE)
Unleaded fuel containing an oxygenate known
as MTBE can be used prov ided 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.
DIESEL ENGINED VEHICLES
Do not use RME (bio-diesel) except in
the case of those proprietary diesel
fuels which contain a mix of up to 5%.
Jaguar can accept no responsibility for
damage caused by using RME in
concentrations greater than 5%.
Use only high quality diesel fuel according to
EN590 or equivalent.
The quality of diesel fu el is variable, depending
on geographic location. Always use premium
or the highest quality fuel available in your
locality. High quality fuel ensures a longer life
for your engine components. Lower grade fuel
contains higher levels of sulphur, which is
detrimental to engine components. If low
quality fuel is used, li ght coloured smoke may
be evident at the exhaust.
Note: Jaguar vehicles ar e capable of running
with up to a 5% blend of bio-diesel, in
accordance with European Standard EN590.
Prolonged use of additives is not
recommended. Do not add paraffin or petrol to
diesel fuels.
If you inadvertently fill your vehicle with
petrol instead of di esel, do not attempt
to start the engine. Contact your Dealer/
Authorised Repairer immediately. Jaguar cars can accept no
responsibility for any damage caused
by running your vehicle with petrol or
vegetable oil in the fuel tank.
SULPHUR CONTENT
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.
In some countries diesel may contain higher
levels 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
Avoid running out of fuel!
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
should be left with the ignition on for 5 minutes
after refuelling before attempting to restart the
engine.
Note: If the vehicle does run out of fuel,
seeking qualified assistance is advisable.
WATER IN FUEL
If the warning WATER IN FUEL is
displayed in the message centre, an
excessive amount of water has
collected in the fuel filter bowl. Seek
assistance from a Jaguar Dealer/
Authorised Repairer to have the filter
drained as soon as possible.
