GENERAL INFORMATION
START/STOP button
The START/STOP button is used to start or
stop the engine, or to turn on the ignition
without starting the engine.
Note: The START/STOP button will only be
operational if a valid Jaguar Smart key is
detected within the vehicle.
Switching on the ignition
To turn on the ignition without starting the
engine, make sure the brake pedal is not
applied and that there is a valid Jaguar Smart
Key in the vehicle, then press and release the
START/STOP button. The warning indicators
illuminate and most electr ical systems will be
operational.
Note: If the brake pedal is pressed when the
START/STOP button is pressed, the engine will
start.
Steering column lock
Your vehicle is fitted with an electronic steering
column lock. The column unlocks when it
detects a Jaguar Smart Key inside the vehicle.
The steering column automatically locks when
the starter switch is turned off and the driver's
door is opened.
If the steering column remains locked, even
with a valid Jaguar Smart Key in the vehicle,
STEERING COLUMN LOCKED is displayed in
the message centre. If this occurs:
1. Press the starter button to return to the
convenience mode.
2. Try again to unlock the steering column
lock, by turning the steering wheel gently
to the left and right.
3. If the malfunction still persists, seek
qualified assistance as soon as possible.
E94135
CAUTION
During vehicle recovery, the Jaguar
Smart Key must remain inside the
vehicle (or be stowed in the starter control unit
in the centre console), so that the steering
column remains unlocked.

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.

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).

Transmission

Driver type recognition
In Sport mode, the transmission monitors
driving style and in combination with sensors
in the vehicle, varies the shift schedule,
fast-off, corner recognition and shift adapt
under braking functions, according to the
driving style.
Manual mode - Jaguar Sequential Shift
Shifts in the Jaguar Sequential Shift manual
mode are made using the steering wheel
mounted shift paddles and are optimised to
provide a rapid response to gear shift requests. Up-shift requests (
+) are optimised for
performance via the s hort shift function,
resulting in firmer feeling shifts than in
automatic mode. Down-shift requests ( -)
utilise a throttle blip duri ng the shift, resulting
in improved shift feel.
The Jaguar Sequential Shift manual mode can
be accessed either temporarily, or
permanently.
Temporary manual gear selection: When the
gear selector is in the D position, manual mode
may be directly accessed by the single action of
operating the steering wheel mounted shift
paddles.
This convenience feature allows immediate but
temporary use of the sh ift paddles when the
gear selector is in D.
If continued use of manua l mode is required,
the gear selector may be subsequently moved
to the S position to enter permanent manual
mode in the currently selected gear.
If the gear selector remains in the D position,
temporary manual mode will be held whilst the
driver is accelerating, decelerating, cornering
or continuing to request shifts via the paddles.
The transmission will revert to automatic
operation after a short pe riod of driving at
steady speed; alternatively the shift-up ( +)
paddle may be held for a short period
(approximately one second) to return directly
to automatic operation in D .
Permanent manual gear selection: Select the
S position, permanent manual mode is then
accessed by the operation of the steering wheel
mounted shift paddles.
The message centre will highlight the currently
selected gear.
E94122

Transmission
142

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
up-shifts 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.
To exit from the Jaguar Sequential Shift
permanent manual mode, either pull and hold
the shift-up paddle for approximately one
second (to return directly to automatic
operation in S ), or rotate the gear selector to
the D position. The transmission will revert to
the D automatic shift mode.
Manual operation
To shift-up, briefly pull the shift-up ( +) paddle
on the right-hand side of the steering wheel
towards you.
To shift-down, briefly pull the shift-down
paddle ( -) on the left-hand side of the steering
wheel towards you.
The message centre display will change to
highlight the requested gear.
Note: The transmission will inhibit up-shifts
and down-shifts if the requested shift would
result in an engine speed outside the normal
operating range of the engine. If this occurs,
the message centre will briefly display the
requested gear selection, but will return to
displaying the current gear.
The Jaguar Sequential Shift mode also has the
following features: Kick-down:
Operation of kick-down in Jaguar
Sequential Shift mode will override the
currently selected gear. The lowest available
gear will be selected for maximum acceleration
and will be highlighted in the message centre
display. Subsequent manu al shifts may then be
selected as usual.
Positive torque: Provides throttle blips on
down-shifts, improving shift feel and response.
Shift assist: The transmission will
automatically up-shift at the engine speed
redline in Jaguar Sequential Shift mode, as if
commanded manually.
The transmission will automatically
down-shift, when the engine speed drops too
low for the currently selected gear.
When the vehicle approaches, or comes to
rest, second gear is au tomatically selected.
Subsequent pull-aways will occur in second
gear, unless the accelerator pedal demand is
high or a down-shift is manually selected, in
which case, first gear will be selected.
In all cases the message centre will display the
current gear.
Note: During sustained braking, if a down-shift
is selected at a speed which would result in the
engine speed exceeding its normal operating
range, the gear change wi ll be indicated in the
message centre, but the down-shift will be
delayed until the vehi cle speed has reduced
sufficiently for the gear selection to be made,
without causing the engine speed to exceed its
normal operating range.

Brakes
144

PRINCIPLE OF OPERATION
Brake pads
Brake pads require a period of bedding in when
new. Drive with extra caution for the first
500 km (300 miles) to avoid the need for heavy
braking.
Brake pad wear warning
When the brake pads are wearing low, the
warning message BRAKE PADS LOW is
displayed in the message centre. Arrange for
your vehicle to be se en by your Dealer/
Authorised Repairer at the earliest opportunity.
Wet conditions
Driving through heavy ra in or water can have
an adverse effect on braking efficiency. Under
such circumstances, it is recommended that
you lightly a pply the brakes intermittently to
dry the brakes.
ABS warning indicator
If this amber warning indicator
illuminates while driving and/or
ABS FAULT is displayed in the
message centre, drive with extra caution, avoid
heavy braking where possible, and seek
qualified assistance as soon as possible.
If this red warning indicator
illuminates while driving and/or the
message LOW BRAKE FLUID is
displayed in the message centre, check the
brake fluid level at the earliest opportunity and
top-up as required. See BRAKE FLUID CHECK
(page 206).
HINTS ON DRIVING WITH ABS
ABS (Anti-Lock Braking System) allows
maximum brake pressure, and thus maximum
braking efficiency, to be applied, and prevents
the road wheels locking. This allows the driver
to retain steering control during heavy braking
under most road conditions.
ABS optimises tyre to road adhesion under
maximum braking conditions, though it cannot
provide increased cornering ability.
WARNINGS
Do not rest your foot on the brake
pedal whilst the vehicle is in motion.
This may cause a light application of
the brakes, which can result in overheating,
reduced brake performance, and excessive
brake wear.
Never allow the vehicle to coast
(freewheel) with the engine turned
off. The engine must be running to
provide full braking assistance. The brakes will
still function with the e ngine off, but far more
pressure will be required to operate them.
If the red brake warning indicator
illuminates, safely bring the vehicle to
a stop, as quickly as possible. Seek
qualified assistance before proceeding.
Never place non-approved floor
matting or any ot her obstructions
under the brake pedal. This restricts
pedal travel and braking efficiency.
WARNINGS
ABS cannot overcome the physical
limitations of braking distance. Nor
can it overcome the lack of grip on a
road surface (e.g. aquaplaning on water).
Braking distance is increased on a
slippery surface. This applies to all
vehicles, even those fitted with ABS.
The driver should not be tempted to
take risks when driving, in the hope
that ABS will correct errors of
judgement. In all cases it remains the driver's
responsibility to driv e with due care and
attention, payi ng particular attention to the
effects of speed, weather, road conditions etc.

145
Brakes

During emergency braking conditions ABS
constantly monitors the speed of each wheel.
ABS varies the brake pressure to individual
wheels, according to the grip available. The
constant alteration of brake pressure can be
felt as a pulsing sensation through the brake
pedal. This is not a caus e for concern, as it is
designed to demonstrate to the driver that ABS
is operating.
ABS braking techniques
For optimum ABS performance, these
instructions on braking techniques during ABS
operation should be followed:
• Do not release the brake pressure when
the pulsating effect is felt. Maintain a
constant pressure until the manoeuvre is
completed.
• To familiarise y ourself with the feel of the
brake pedal during ABS braking, practise
an emergency stop pr ocedure, always
making sure it is safe to do so. With the
seat belts fitted to all occupants, drive the
vehicle at 32 km/h (20 mph) and brake
sharply.
• ABS enables the driver to steer around
obstacles during em ergency braking.
However, the consequences of turning
sharply at high speed cannot be overcome
by the ABS.
• Do not attempt to pump the brakes to
avoid skidding, as this can interfere with
ABS operation. The ABS will not allow the
wheels to skid under normal road
conditions.
• The ABS will tend to keep the vehicle
straight during braki ng. Because braking
distances may increase under certain road
conditions, it is nece ssary to plan and
make turning manoeuvres as early as
possible.
Electronic Brakeforce Distribution (EBD)
EBD balances the distribution of braking forces
between the wheels on the front and rear axles,
to maintain maximum braking under all vehicle
loading conditions.
For example; Under light loads, EBD applies
less braking effort to the rear wheels, to
maintain stability. Conv ersely, it allows full
braking effort to the rear wheels when the
vehicle is towing or is heavily laden.
A fault with the EBD system is
indicated by illumination of the red
brake warning indicator and the
message EBD FAULT is displayed in the
message centre. Gently stop the vehicle, as
soon as safety permit s, and seek qualified
assistance.
