Starting the engine
134

Engine block heaters
Engines are more difficult to start when the
ambient temperature is very low. In
geographical areas where temperatures below
-10°C (14°F) are experienced frequently, it is
advisable to fit an engine block heater. The
block heater will have an insulated connector at
the front of the vehicle, which is connected to a
mains supply using a suitable extension cable.
The heater can remain in use overnight if
required. Typically, an e ngine block heater will
use between 400W and 1000W per hour.
For further information consult your Jaguar
Dealer/Authorised Repairer.
If the engine fails to start
When pressing the engine START/STOP button
to start the engine, if the security status
indicator lamp on the top surface of the
instrument panel rema ins flashing, a fault
condition is indicate d. Seek qualified
assistance as soon as possible.
Note: If the Jaguar Smart Key is placed in the
door pocket, it may be outside the range of the
sensors when the door is opened.
Note: If the fuel system inertia switch has
tripped, the ignition circuit will be isolated.
See FUEL CUT-OFF (page 177).
Petrol engines
If the engine persistently fails to start, press the
START/STOP button (without applying the
brake pedal) to return the ignition to
convenience mode. Slowly depress the
accelerator pedal fully, hold it in this position
and press the START/STOP button with the
brake pedal applied, the engine will start to
crank. Release the accelerator pedal when the
engine starts.
If the engine still fails to start, consult your
Dealer/Authorised Repairer.
Diesel engines
If the engine persistently fails to start, press
and hold the START/STOP button (with the
brake pedal applied). Keep the START/STOP
button and the brake pedal pressed until the
engine starts, then release.
If the engine still fails to start, consult your
Dealer/Authorised Repairer.
SWITCHING OFF THE ENGINE
With the gear selector in position P, press the
engine START/STOP button. The engine will
stop and the ignition syst em will return to
convenience mode. The audio, telephone and
touch-screen systems will revert to stand-by
mode and the JaguarDrive selector will retract
into the centre console. Pressing the
START/STOP button ag ain (without pressing
the brake pedal) will activate the systems.
CAUTION
The fitting of an engine block heater
does not eliminate the need for
antifreeze.
WARNING
Never switch off the engine when the
vehicle is in motion.

Transmission
138

P should be selected before switching off the
engine. However, it is possible to switch the
engine off with R, D or S selected - the selector
will automatica lly select P, while retracting into
the centre console.
Note: If the engine is switched off with N
selected, the system will wait for 10 minutes
before selecting P. This procedure is to allow
the vehicle to be conveyed through a car wash
only and should not be used for vehicle
recovery purposes.
To prevent the transmission from
automatically selecting P (e.g. for vehicle
recovery purposes), it is necessary to activate
the Emergency Park Release.
See TRANSPORTING THE VEHICLE
(page 254).
Selector positions
P - Park: Use when parked. In this position the
transmission is locked, do not attempt to select
P if the vehicle is moving.
Note: P will be selected automatically when the
engine is switched off.
R - Reverse: Do not select if the vehicle is
moving forward.
N - Neutral: Disconnects drive to the wheels.
Use the parking brake when stopping
temporarily with N selected.
D - Drive: Gear changing is automatic for all six
forward gears. The shift points are determined
by accelerator pedal pos ition and road speed,
to provide the best ba lance of performance,
refinement and fuel economy, for the large
majority of driving conditions.
S - Sport: Gear changing is automatic for all six
forward gears, with modified gear shift points
to maximise the ve hicle response in
demanding driving condi tions. This mode is
not suitable for town or highway cruising. Note:
Both D and S positions also offer
additional features, wh ich are listed under
Automatic mode and Sport mode , later in this
section.
Stationary vehicle
When the vehicle is stationary, the selector
may be left in D or S, unless the vehicle is to be
parked. When stopping fo r extended periods,
either select P or apply the parking brake and
select N.
Selector interlock
The transmission is equippe d with an interlock,
to prevent inadvertent selection of a drive gear
(D , S or R) from the P or N positions. To
release the interlock to select a drive gear,
press the brake pedal while making the
selection.
Ensure the required driv ing range has selected
prior to releasing the brake pedal. The range
indicator ( R, D or S) on the selector and
message centre disp lays, will illuminate
continuously to confirm selection.
Note: If the brake pedal is released too early
during selector rotation from P or N to a driving
range ( R, D or S), then the selected range will
not be engaged. The selected range will flash
on the selector and message centre displays.
To obtain the selected range, press the brake
pedal, select P or N and reselect the required
range, ensuring the brake pedal is depressed.
If N is selected for less than 2 seconds (e.g.
when moving the selector between R and D),
the interlock will not ac tivate and the brake
pedal will not need to be pressed.
Note: The interlock is deactivated when the
vehicle is travelling at more than 5 km/h
(3 mph).

Driving hints

ECONOMICAL DRIVING
There are two main factors which influence fuel
economy, the way the vehicle is driven and
maintenance.
Driving tips for economy
•Avoid unnecessary jour neys, especially
short stop-start trips.
• Accelerate smoothly and gently from a
stand still.
• Allow time to brake gently and smoothly.
• Be aware of traffic and road conditions
ahead, and take action in time to avoid
hard braking or acceleration.
• When stationary apply the park brake, and
select neutral.
• Turn off the air conditioning when not
needed.
Maintenance and fuel economy
Regular servicing by a Dealer/Authorised
Repairer, along with regular checks by the
driver are essential fo r vehicle longevity and
fuel economy.
The condition of the engine (oils, filters, spark
plugs, settings etc.) tyre pressures, and wheel
alignment, will all have a bearing on fuel
economy. For this reason it is essential that the
vehicle is checked regularly by the driver and
serviced by an approved Dealer/Authorised
Repairer at the correct intervals.
Note: If you are in any doubt about the
maintenance requirement s, intervals, or
checks required, contact your Dealer/
Authorised Repairer for advice.

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

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.
