Raising the rear seats
The process for raising the rear seat is the
reverse of folding.
HEATED SEATS
Note: To prevent the battery from becoming
discharged the seat heaters will only operate
when the engine is running.
Seat heating is adjusted through the vehicle
touch-screen (from either the Climate or the
Home menu). The seat heaters have three
temperature levels, indica ted by the three bars
adjacent to each seat icon.
• Touch the left or right -hand seat icon (as
appropriate) to activate the seat heater,
which initially selects the maximum
temperature level (three bars).
• Touch the icon a second time to select the
medium temperature setting (two bars).
• Touch the icon a third time to select the
lowest temperature setting (one bar).
• Touch the icon again to switch off the seat
heaters.
WARNINGS
Ensure that when the seat back is
raised, the seat belts are routed
correctly and are not trapped by the
seat back.
Ensure that when the seat back is
raised, the locking mechanism is fully
engaged. Failure to do so can
increase the risk of death or serious injury in
the event of an accident or sudden manoeuvre
or heavy braking.
Before driving, ensure that the head
restraints are correctly fitted to the
rear seats.

The rotating air vents acti vate and rotate out of
the fascia when the engine START/STOP
button is pressed, provided the climate system
has not been manually switched off. Adjust the
volume of air usi ng the thumbwheels ( 1) and
the direction of the air using the direction
controls ( 2), to suit your requirements.
It is possible to set the air vents so that they
remain permanently on view, even when the
ignition is switched off. From the touch-screen Climate menu, select
Settings
. Select Vent rotation Always open .
Rear vents
The temperature of the air supplied by the rear
air vents is dependent on the combined
temperature settings for the driver and front
passenger. For example, if the driver
temperature is set to 21°C (70°F) and 20°C
(68°F) for the front passenger, the temperature
of the air supplied to the rear of the vehicle will
be approximately 20.5°C (69°F).

temperatures to be independently
adjusted. Press the upper (red)
button to increase temperature and the lower
(blue) button to decrease temperature.
Both driver and passenger temperatures are
displayed on the touch-screen.
Selecting the maximum or minimum
temperature settings for the driver temperature
zone, causes the disp lay to change to HI or LO
respectively. This cancels AUTO mode.
To quickly change from HI or LO to a
convenient mid-rang e temperature of 22°C
(72°F), press and hold AUTO for a few
seconds.
Note: The maximum possible temperature
differential between the driver and passenger
settings is 3°C (5.4°F)
Windscreen defrost and demist
To remove frost or heavy misting
from the windscreen, press the DEF
button. The following functions will
activate:
• The blower switches on at a high speed
(blower speed can be adjusted manually to
suit).
• The air conditioni ng activates (to
dehumidify the air) and cannot be switched
off.
• Recirculation is canc elled and cannot be
selected.
• The front and rear screen heaters switch
on automatically (if th e engine is running).
To deselect, press the DEF button again or

The front (F) and rear ( R)
screen heaters, may be
switched on and off in
any mode, including with
the climate control system off. However, they
will only operate when the engine is running.
The front screen heater switches off
automatically after 5 minutes. The rear screen
heater switches off automatically after 21
minutes.
The screen heaters can be manually deselected
using the push buttons.
In cold ambient conditions, the front and rear
screen heaters will switch on automatically for
the timed period when the engine is started.
The front and rear screen heaters will
automatically come on at temperatures below
5°C (41°F).
Auto mode
Automatic operation utilises
the air conditioning and other
climate controls , to provide a
controlled environment over a
temperature range of 16°C to 28°C (59°F to
83°F) and should be rega rded as the normal
operating mode.

engine reaches normal operating temperature.
Recirculation
Press to turn recirculation on
or off. The button indicator
illuminates when recirculation
is turned on.
When selected, the air is recirculated inside the
vehicle. This helps to ma intain a high or low
temperature, and is useful for preventing
fumes from entering the vehicle.
Recirculation may also be selected in AUTO
mode, if the climate control system detects
high levels of pollution in the atmosphere
outside the vehicle (if a smog sensor is fitted).

the air conditioning on.
The air conditioning system is
controlled automatically in AUTO mode to
maintain the desired temperature and humidity
(even if higher temperature settings are
selected).
The air conditioning system is also switched on
automatically in defrost mode ( DEF) in order to
dehumidify the air.
Note: Water may collect unde rneath the vehicle
when parked. This is moisture expelled from
the interior of the vehicle by the air
conditioning system a nd is not cause for
concern.
Heated/climate seats and heated
steering wheel
The heated seats, climate seats and heated
steering wheel can be controlled from both the
Home and Climate menus on the touch-screen.

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.

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.

RUNNING-IN
Apart from a few precautionary
recommendations, there are no strict
running-in procedures for this vehicle.
By observing the following advisory
precautions you will ensure maximum engine,
transmission and brake life for your vehicle:
Engine
• Allow the engine to reach operating
temperature before operating at engine
speeds over 3 500 rev/min.
• Vary the speed frequently.
• From 1 500 kilometres (940 miles)
onwards, gradually in crease performance
of the vehicle up to the permitted
maximum speed.
Engine oil consumption
A certain amount of oil consumption is normal.
The rate of consumpt ion will depend on the
following:
• The quality and viscosity of the oil.
• Climatic conditions.
• The speed at which th e engine is being
operated.
• Road conditions.
Drivers should expect above normal
consumption when the engi ne is new, and after
running-in if high speeds are sustained.
Brakes
To ensure that brake pa ds reach their optimum
wear and performance condition, usually
within 500 kilometres (300 miles), it is
recommended that the following points are
observed.
• Where possible, avoid heavy or harsh
braking, as this can result in damage to the
brake pads and discs.
• Avoid prolonged use of the brakes
(e.g. when descending severe gradients).
• Frequent light application of the brakes is
desirable. This helps to fully bed-in the
brake pads.
These running-in guidelines also apply when
new brake discs or pads have been fitted.
Final drive unit
During the first 1 500 kilometers (940 miles):
•Avoid full throttle a pplications and do not
exceed 190 km/h (120 mph). Observe the
national speed limits in the country in
which you are travelling.
• Do not participate in motor racing events,
test track days, sports driving schools or
similar for the first 8 000 kilometers
(4 975 miles).
