Transmission

Limp-home mode
Note: The driver should be aware that the
vehicle’s performance will be reduced and
must take this into account when driving. Also
the use of the Jaguar Sequential Shift paddles
will be disabled. In this event, seek qualified
assistance as soon as possible.
In the unlikely event of an electrical or
mechanical failure, tran smission operation will
be limited. The vehicle gear selector ranges P,
R , N , D and S may still be used to enable the
vehicle to be driven to a safe area.
Some faults will cause the selector to be locked
in position until the igniti on is switched off. If
the selected range flashes, it signifies that the
driver request cannot be engaged. Re-select N
and repeat the attempt.
If the transmission is still unable to select the
requested gear, contact your Dealer/
Authorised Repairer.
Message centre display
The message centre will confirm the
JaguarDrive selector pos ition (selected gear). Selector position is sh
own highlighted at the
top of the message cent re and confirmed by
the dot on the circular representation of the
selector.
If manual mode is se lected, the numbers 1 to 6
appear at the top of the display, with the
currently selected gear highlighted.
Note: With the transmission set to permanent
manual mode and Dynamic mode selected,
when the rev limit is re ached, the gear position
indicator in the message centre will glow
amber, to indicate that the next gear should be
selected.
The message centre may also display the
following messages with associated warning
indicators:
ENGINE SYSTEMS FAULT (Red)
RESTRICTED PERFORMANCE (Red or Amber)
GEARBOX FAULT (Amber)
If any of these messages are displayed it is
likely that loss of power or driveability will be
experienced. Seek qualified assistance as soon
as possible.

DYNAMIC MODE
(V8 petrol and diesel vehicles only)
Press to operate. Dynamic mode
co-ordinates the vehicle's control
systems to deliver a high
performance driving experience. This setting
enhances key vehicle systems so that the
vehicle's full potential can be exploited. The
vehicle's responses are aimed at involving the
driver more in focused and purposeful driving,
helping swift progress.
Note: When the transmission is set to
permanent manual mode (i.e. using the
paddles to change gear while in Sport mode)
and Dynamic mode is selected, transmission
upshifts are fully controlled by the driver. This
means that the transmissi on will not change up
a gear automatically, even when the vehicle's
rev limit is reached. When the rev limit is
reached, the gear position indicator in the
message centre will glow amber, to indicate
that the next gear should be selected.
Note: Dynamic mode cannot be active at the
same time as Winter m ode. Dynamic mode will
remain selected for approximately six hours
after the ignition is swit ched off, after which
point it will need to be reselected if required.
STABILITY CONTROL
Dynamic Stability Control (DSC)
Dynamic Stability Contro l (DSC) is operational
whenever the engine is running, unless it has
been manually switched off. When the system
is operating, the warn ing indicator in the
instrument panel will flash.
The DSC system controls the Anti-lock Braking
System (ABS), traction control and yaw control
of the vehicle.
The DSC system assists the driver in retaining
directional control of th e vehicle in situations
where the vehicle is sliding (understeer or
oversteer). It must not encourage the driver to
drive beyond the limit of adhesion or at speeds
higher than those suitable for the prevailing
road and traffic conditions.
DSC applies braking pres sure to individual
wheels if excessive variation is detected. This
ensures that the vehicle follows the driver’s
intended direction of travel as closely as
possible.
Traction control will intervene to control wheel
spin by automatically reducing the power
output from the engine and applying braking to
individual wheels. This improves acceleration,
particularly on surfaces with uneven friction
(e.g. one wheel on ice with another on tarmac).
Note: For recommended DSC mode selection,
refer to the JaguarDri ve Control scenarios
section in this handbook.
WARNING
The fact that the vehicle is fitted with
DSC, must never allow the driver to
be tempted into taking risks which
could affect his or her sa fety or that of other
road users. In all cases, it remains the driver’s
responsibility to drive sa fely according to the
prevailing conditions.

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.

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.
Rinse thoroughly and dry with a chamois
leather or synthetic substitute.
Using an automatic wash
Note: Regular use of automatic car washes
tends to dull the lustre of the paintwork.
1. Drive up to the entry of the car wash and
onto the conveyor.
2. Select N (Neutral) using the JaguarDrive
selector.
3. Press and release the engine START/STOP
button to stop the engine. The JaguarDrive
selector should remain raised and the
selector and message centre should
indicate that N is selected. 4.
The vehicle should rema in in this condition
while it is conveyed through the car wash.
5. At the end of the wash cycle, when directed
to start the engine by the car wash
instructions, press the brake pedal and
press and release the engine START/STOP
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.

petrol engines is checked automatically at all
times by the electronic dipstick.
Severe driving conditions
When a vehicle is operated in severe
conditions, more frequent attention must be
paid to servicing requirements.
Severe driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading. •
Driving in extremely hot or cold
conditions.
• Driving in areas using road salt or other
corrosive materials.
• Towing a trailer or driving in mountainous
conditions.
Contact your Dealer/Authorised Repairer for
advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporati ve control equipment,
designed to meet specific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissi ons, engine performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes, it is essential that any dynamometer
testing is carried out only by a qualified person,
familiar with the dynamometer testing and
safety procedures practised by
Dealers/Authorised Repairers.
CAUTION
Ensure that you take notice of any
message centre information and
warnings relating to engi ne oil level (V8 petrol

The oil consumption of an engine is influenced
by many factors. Unde r high loads an engine
will consume more oil than usual. Diesel
engines consume slightly more oil than petrol
engines.
Above normal oil consumption should be
expected when the engine is new.
Check the oil level weekly , when the engine is
cold and with the vehicle resting on level
ground.

CAUTIONS
If the message ENGINE OIL PRESSURE
LOW is displayed, st op the engine as
soon as it is safe to do so and seek qualified
assistance. Do not start the engine until the
cause has been identified and rectified.
Your vehicle’s warranty may be
invalidated if damage is caused by the
use of improper engine oil. Low quality or
obsolete oils do not pr ovide the protection
required by modern, high performance
engines. Failure to use an oil that meets the
required specification could cause excessive
engine wear, a build up of sludge and deposits
and increased pollution. It could also lead to
engine failure.
Do not use oil additi ves of any type as
engine damage coul d occur. Use only
specified lubricants.
