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 PARTICULATE FILTER (DPF)
The Diesel Particulate Filter (DPF) forms part of
the emissions reduction system fitted to your
vehicle. The DPF will remove a high proportion
of the harmful car bon microspheres (soot)
before they leave the exhaust. It achieves this
by filtering out the particles, which are then
stored until they are burnt away and the filter is
emptied.
Regeneration
Unlike a normal filter which requires periodic
replacement, the DPF has been designed to
regenerate, or clean itself, to maintain
operating efficiency. Th is regeneration process
takes place automatically in most cases.
However, some unfavourable driving
conditions may mean th at the regeneration
process must be initiate d deliberately by the
driver.
Warning indicators and messages
If regeneration cannot be achieved
automatically by the system, due to short
journeys for example, the driver will be notified
via a warning indicator or message.
DPF FULL
If this message appears in the message centre
(with a red backlight), the vehicle should be
taken to your Dealer/Authorised Repairer as
soon as possible.
DPF FULL SEE HANDBOOK
If this message appears in the message centre
(with an amber backlight), the driver should
carry out the DPF regene ration procedure that
follows, as soon as possible.
CAUTION
The regeneration procedure produces
high temperatures in the DPF. Heat can
be felt radiating from beneath the vehicle,
which is normal and not a cause for concern.
However, the vehicle should not be parked
over combustible material, particularly during
dry weather. The heat generated could be
sufficient to start a fire when in close proximity
to combustible material such as long dry
grass, paper etc.
CAUTION
Failure to take the appropriate action
when a warning message appears, may
result in damage to the engine and DPF
system, increased vehicle emissions and
costly repairs.

Regeneration procedure
If the warning DPF FULL SEE HANDBOOK
appears in the message centre, carry out the
following procedure as soon as possible.
Note: At all times during this procedure you
should observe all releva nt speed limits, laws
and regulations. Always ta ke account of traffic
and weather conditions and drive with
consideration for other road users.
1. Drive the vehicle until the engine reaches
normal operating temp erature. The engine
should not be left idli ng to achieve working
temperature.
2. Drive the vehicle for a further twenty
minutes, keeping the vehicle at a steady
speed between 75 km/h (45 mph) and
120 km/h (75 mph).
Keeping a constant speed enables the DPF
to regenerate more efficiently. It is
therefore recommended that Cruise
control is used to achieve this, if possible.
3. If regeneration is su ccessful, the warning
message will extinguish. If the message
remains, repeat the process.
If the warning message fa ils to extinguish after
60 minutes of driving, contact your Dealer/
Authorised Repairer for assistance.

Transmission

AUTOMATIC TRANSMISSION
The transmission system is designed to
operate in two distinct modes, conventional
automatic and Jaguar Sequential Shift.
The automatic modes are accessed by the gear
selector:
•D - Drive - automatic shifting.
• S - Sport - sport automatic shifting.
The Jaguar Sequential Shift mode enables
sequential manual gear selection in D
(temporary) and S (permanent) modes, via the
steering wheel m ounted paddles.
Note: In addition to the st andard shift patterns
available in D and S, the transmission will
adapt to differing conditions by modifying shift
points, based upon vehicl e sensor information
for road gradient, cornering, braking pressure
and driving style.
JaguarDrive selector
The JaguarDrive selector elevates out of the
centre console when the engine is started, in
readiness for gear selection. Press the brake
pedal, then rotate the control to select the
chosen gear ( P, R , N or D) or, from D, press
down on the control and rotate to select S
(Sport).
CAUTIONS
Never select the Park ( P) position whilst
the vehicle is in motion. Doing so may
cause serious damage to the transmission.
Never select the Reverse ( R) position
whilst the vehicle is in forward motion.
Doing so may cause serious damage to the
transmission.
Never select a forward gear whilst the
vehicle is in rearward motion. Doing so
may cause serious damage to the
transmission.
Do not rev the engine or allow it to run
above normal idle speed while selecting
D or R, or while the vehicle is stationary with
any gear selected.
Do not allow the vehicle to remain
stationary for any length of time, with a
gear selected and the engine running. Always
select P or N if the engine is to idle for a
prolonged period.
E94119

Transmission

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).

Transmission

If the selector fails to elevate
If the JaguarDrive selector is obstructed when
the engine is started, it may be prevented from
elevating out of the centre console. If this
occurs, turn off the ignition, ensure that the
selector is not obstruc ted and then start the
engine. The selector s hould elevate as normal.
If the selector still fails to elevate, even if there
is no obstruction, a faul t in the system is
indicated. The selector ca n still be used in the
lowered position, but be aware that it will not
automatically select P when the engine is
switched off, so P should be sele cted manually.
The fault should be re ctified by a Dealer/
Authorised Repairer at the earliest opportunity.
Starting
In the unlikely event that the selector did not
rotate back to P when the vehicle was
previously switched off, and the selector has
remained in R, D or S, it will not be possible to
start the engine. The vehicle will go to ignition
on. The selected range will flash and the
selector will now be unlocked, to allow the
driver to select P and start the engine.
Automatic mode
To select Drive (D) when the vehicle is
stationary:-
1. Apply the foot brake.
2. Rotate the gear selector to D.
When in D the transmission will automatically
select the most appropriate gear for the current
driving conditions.
Note: When a gear is selected the vehicle may
begin to move as soon as the foot brake is
released.
Kick-down
When D is selected and the accelerator pedal is
depressed fully, the transmission will
downshift to the lowest appropriate gear. Once
the accelerator pedal is returned to a normal
driving position, the tr ansmission will up-shift
to the highest appropriate gear.
Note: Kick-down operation will vary according
to road speed, current gear in use and
accelerator movement.
E94120

Fast off
Activated when rapidly lifting off the
accelerator pedal and takes account of road
gradient. This feature inhibits up-shifts,
enhancing pe rformance.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Shift adapt under braking
Under braking, the transmission will vary the
down-shift point in proportion to braking effort
and road gradient. This feature works in
conjunction with the posit ive torque function,
resulting in a smoother down-shift.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Corner recognition
Inhibits up-shifts during cornering, to provide
improved vehicle balance.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Road gradient recognition
When the vehicle is being driven on an uphill
gradient, the transmission adapts the shift
pattern to make better use of engine power.
When driving on a long downhill gradient, the
transmission may automatically select a lower
gear, to increase engi ne braking. Selecting
Sport mode (S ) will increase the tendency of
the transmission to select a lower gear in these
conditions, further incr easing engine braking.
Note: It is also possible to manually select a
lower gear to increase e ngine braking via use of
the shift paddles.
Sport mode
To select Sport mode:
1. With the selector in D, push down on the
selector.
2. Rotate from D to S.
Note: When Sport mode is selected SPORT will
be displayed in the message centre, and the
selector indicator will illuminate.
Sport mode enhances th e responsiveness of
the transmission, to prov ide a sporting feel to
driving the vehicle. Sport mode is
recommended for over taking manoeuvres and
for when rapid progress is desired.
To return to automatic m ode move the selector
lever back to the D position. The D on the
selector display will illuminate to confirm that
automatic mode has been selected.
