Driving dynamics

TracDSC
TracDSC is an alternative setting of DSC with
reduced system interventions. With TracDSC
engaged, traction may be somewhat increased,
although stability may be reduced compared to
normal DSC. TracDSC is intended for use only
on dry tarmac, by suitably experienced drivers
and should not be select ed for other surfaces
or by drivers with insufficient skill and training
to operate the vehicle safely with the TracDSC
function engaged.
The less restrictive TracDSC setting may be
preferred, for example, by expert drivers
engaged in high performance driving on dry
Tarmac surfaces such as tracks and circuits.
Switching between DSC and Trac DSC
• Press and hold the DSC switch for less
than 10 seconds.
• The message centre will temporarily
display either Trac DSC or DSC ON.
• The warning indicator in the instrument
panel will illuminate while Trac DSC is
selected.
• The warning indicator will flash when DSC
or Trac DSC is active.
Note: If cruise control is engaged, it will
automatically disengage if stability control
activates.
Switching between DSC OFF and ON
Switching DSC OFF
• Press and hold the DSC switch for more
than 10 seconds.
• The message centre will display DSC OFF
and a short warning chime will sound.
• The warning indicator in the instrument
panel will illuminate.
Switching DSC ON
If DSC is OFF:
• Press and release the DSC switch.
• The DSC system will switch on, the
message centre will temporarily display
DSC ON .
• The warning indicator in the instrument
panel will be extinguished.
Note: Switching the engine off and then on
again, will always revert DSC status to DSC ON,
regardless of which Ja guarDrive Control mode
is selected.
WARNING
Vehicle safety may be reduced by
inappropriate use of TracDSC.
TracDSC should only be used in
suitable conditions.

Driving dynamics
172

Note: In rare circumstances, when TracDSC is
selected or DSC is o ff, high acceleration on
rough roads may cause DSC to switch back on.
This prevents high loads on the vehicle
driveline. DSC will su bsequently remain on,
unless TracDSC is selected or DSC is switched
off manually.
Stability control indicator
If there is a fault, the warning
indicator will ill uminate in the
instrument panel and the message
centre will display DSC NOT AVAILABLE with
an amber backlight.
It is safe to drive the vehicle, but the DSC
system will not activa te under wheel spin or
slide conditions. You should seek qualified
assistance as soon as possible.
Adaptive dynamics
(Supercharged vehicles only)
Jaguar Adaptive dy namics continuously
monitors the road a nd driver inputs and
optimises the vehicle suspension settings for
ride comfort and control.
The adaptive dynamics system is linked to
Dynamic mode, modifying the suspension
settings for a more sporting character.
If the message centre displays the message
ADAPTIVE DYNAMICS FAULT , a fault has been
detected in the adaptive dynamics system.
Seek qualified assistan ce as soon as possible.
Active Differential Control (E-diff)
(Supercharged vehicles only)
The E-diff improves trac tion when one driven
wheel has more grip than the other. This
improves progress out of corners and on
patchy or uneven surfaces. The E-diff can also
increase stability in oversteer situations,
depending on road c onditions and driver
inputs. Settings for the E-diff are made automatically,
without the need for driver selection.
If there is a fault with the E-diff system, the
message centre will display
EDIFF SYSTEM
FAULT . If DSC is off, then TracDSC will be
selected automatically. The driver can still
switch between DSC mode s, as normal and the
vehicle is safe to dr ive, but seek qualified
assistance as soon as possible.
Note: If the E-diff is active continuously for an
extended period (e.g. on a patchy surface with
DSC off) then the E-diff may be temporarily
deactivated to prevent ov erheating. If DSC is
off, then TracDSC will be selected
automatically. The mess age centre will display
EDIFF NOT AVAILABLE . The driver can still
switch between DSC modes as normal and the
E-diff will become availa ble again automatically
when it has cool ed sufficiently.

SAFETY PRECAUTIONSFUEL QUALITY
Water in fuel
Petrol 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 expl osion may cause serious
injuries and/or death.
Only use containe rs specifically
designed for carrying fuel and always
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 a nd 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 expl osion 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.
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 se rvice actions should be
entrusted to a Dealer /Authorised Repairer.The presence of any unusual fumes
(e.g. petrol or exhaust fumes) in the
passenger compartment and/or
luggage compartment, should be corrected
immediately by a Dealer /Authorised Repairer.
If you must drive unde r these conditions, do
so only with all windows fully open.
CAUTIONS
If the warning WATER IN FUEL is
displayed in the message centre, an
excessive amount of wate r has collected in the
fuel filter bowl. Seek assistance from a Jaguar
Dealer/Authorised Repairer to have the filter
drained, as soon as possible.
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 petrol, as using
lower quality fuels ca n cause damage to
the engine, fuel and emission control systems.
Fuel system cleaning agents should not
be used, unless a pproved by Jaguar.
Unapproved products may be harmful to fuel
system components on your vehicle.
It is the driver’s resp onsibility 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.
WARNINGS

175
Fuel and refuelling

Unleaded fuel
Unleaded fuel must be used for the emission
control system to operate properly. Its use will
also reduce spark plug f ouling, exhaust system
corrosion and engine oil deterioration.
Octane rating
The recommended unleade d fuel should have
an octane rating of 95 RON (Research Octane
Number) or higher. Howe ver, you may also use
unleaded fuel with a lower RON, but
performance will be reduced. The minimum
octane rating for fuel to be used is 91 RON.
Note: Using unleaded fuel wi th a lower octane
rating than recommended, can cause
persistent heavy engi ne knock (a metallic
rapping noise). If severe , this can lead to
engine damage.
If a heavy knock is dete cted, even when using
fuel to the recommended octane rating, or if
you hear knock while ho lding a steady speed
on level roads, consult your Dealer/Authorised
Repairer to have the problem corrected. Failure
to do so is misuse of the vehicle, for which
Jaguar Cars is not responsible. However,
occasional, light knock for a short time while
accelerating or driv ing up hill, may occur.
ALTERNATIVE FUELS FOR PETROL
ENGINES
Fuels containing alcohol
Some fuel suppliers sell fuel containing alcohol
without advertising its presence. Where
uncertainty exists, check with the service
centre 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 opera ting difference with
fuel containing Ethanol. If a difference is
detected, the use of c onventional unleaded fuel
should be resumed.
Methanol
Some fuels contain Meth anol (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. Fuel 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.
CAUTIONS
Fuel containing alc ohol 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 a nd fuels system damage
will occur.
CAUTION
Wherever possible avoid using fuel
containing Methanol.

Fuel and refuelling
176

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 comp anies have announced
the availability of reformulated fuels. These
fuels are specially formulated to further reduce
vehicle emissions. Jagua r fully supports all
efforts to protect and maintain ambient air
quality and encourages the use of reformulated
gasoline, where available.
DIESEL ENGINED VEHICLES
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, light 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.
Winter grade diesel fuel
To make sure of relia
ble diesel engine
operation during cold seasonal periods, Winter
grade fuel must be used . This fuel is normally
available from fuel retailers during these
periods and the fuel companies adjust the fuel
quality to suit climatic conditions.
If the vehicle is not filled with Winter grade
diesel fuel, it is recommended that the engine
is idled for a period of over two minutes after
starting, to prevent fuel solidification during
operation.CAUTION
Do not use RME (bio-d iesel) except in
the case of those propr ietary diesel fuels
which contain a mix of up to 5%. Jaguar can
accept no responsibility for damage caused by
using RME in concentrat ions greater than 5%.
CAUTIONS
If you inadvertently fill your vehicle with
petrol instead of di esel, do not attempt
to start the engine. Contact your Dealer/
Authorised Repairer im mediately. Attempting
to start the engine with petrol in the fuel tank,
will cause extensive dama ge to the engine and
fuel system, which will not be covered by your
Jaguar warranty.
Jaguar cars can ac cept no responsibility
for any damage caused by running your
vehicle with petrol or ve getable oil in the fuel
tank.

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.

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.
