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.

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.

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.

Emergency Brake Assist (EBA)
The EBA system measures the rate at which the
brake pressure increases. If the system detects
an emergency braking situation, EBA
automatically init iates full braking effect. This
can reduce stopping dist ances in critical
situations.
EBA stops operating as soon as the brake pedal
is released.
EBA is part of the Dynamic Stability
Control (DSC) system and a fault
with the EBA system is indicated by
the amber DSC warning indicator illuminating
and DSC NOT AVAILABLE (with amber
backlight) displaying in the message centre.
Seek qualified assistan ce as soon as possible.
Brake vacuum assist
(V6 petrol models only)
When the engine is cold and/or engine vacuum
is low, Brake vacuum assist provides additional
brake pedal assistance. When the function is
operating, a pulsation ma y be felt through the
brake pedal - this is not a cause for concern.
A fault is indicate d by the message BRAKE
ASSIST FAULT (with amber backlight)
appearing in the message centre. Increased
brake pedal effort may be required to slow the
vehicle when the engine is cold and/or engine
vacuum is low. Seek qualified assistance.
ELECTRIC PARKING BRAKE (EPB)
The switch which operate s the parking brake is
mounted on the centre c onsole to the rear of
the gear selector.
To engage the parking brake (1): Pull the
parking brake switch up wards and release. The
switch will return to the neutral position. The
Parking brake warning and Brake fluid low
warning indicator on the instrument panel will
illuminate.
The Drive Away Release feature allows the
parking brake to release automatically as the
vehicle is driven away.
To disengage the parking brake (2): With the
ignition system on or with the engine running,
apply the foot brake and press the parking
brake switch down.
If the parking brake is a pplied while the vehicle
is stationary and D or R is selected, applying
the throttle will auto matically release the
parking brake.
The parking brake is also automatically
released when the gear selector is moved from
the P position.
WARNING
The EBA system is an additional
safety system; it is not intended to
relieve the driver of his or her
responsibility for exercising due care and
attention when driving.12

PRINCIPLE OF OPERATION
Note: Once the system has been activated by
selecting reverse or using the switch, the front
and rear sensors are active when the gear
selector is in neutral. Therefore, if an obstacle
is detected an audible warning tone will sound.
The parking aid is automatically in standby
when the ignition is on and provides the driver
with information on most obstructions, and
their distance from the vehicle, when
manoeuvring. This is ac hieved by using four
ultrasonic sensors on each bumper.
When objects are detected the Park aid will
emit a warning tone which increases in
frequency and then becomes constant, as the
vehicle gets closer to the object.
USING THE PARKING AID
Touch-screen
To set the volume of the parking aid warning
tones:
• Select Vehicle from the touch-screen
Home menu, then select Veh. settings.
• Select Parking , then select Vol. presets.
Touch the Parking aid + or - button to increase
or decrease the warning tone volume.
Note: This adjusts both front and rear speaker
volume.
WARNINGS
It remains the driver’s responsibility
to be vigilant when reversing. Small
children or animals may not be
detected by the system.
It remains the driver’s responsibility
to detect obstacles and estimate the
vehicle’s distance from them. Some
overhanging objects , barriers, thin
obstructions or painted surfaces which could
possibly cause damage to the vehicle may not
be detected by the system. Always be vigilant
when reversing.
CAUTIONS
Objects moving away from the vehicle
will be reported. Howe ver, whilst driving
away, object warning may be temporarily
reported due to ground reflection.
Systems using the same frequency
band as the front parking sensors, may
cause irregular tones to be emitted.

Parking aid

When the parking aid is active, a pop-up screen
is initiated displaying a plan view of the vehicle
and the immediate surrounding area. This can
be cancelled by touching the screen within the
pop-up area.
Note: If a rear-view camera is fitted, when
reverse gear (R ) is selected, the camera display
is selected automatically. To view the parking
aid display, touch the screen. The rear view
camera will indicate wh en a rear parking aid
sensor has been activated, by showing a red
panel over the relevant area of the camera
display. See Rear view camera (page 152).
Rear parking aid
The rear parking aid operates only with the
ignition is on and reve rse gear selected. If
obstacles are detected within operating range
(shown in next illustra tion), the parking aid
automatically provides an audible proximity
warning. 1.
Approximately 600 mm (24 inches).
2. Approximately 1800mm (71 inches).
Note: The outer rear sensors ( 1) will show
visual detection on the touch-screen, before
the audible warn ing is given.

Front and rear parking aid
When both front and rear parking aids are
fitted, a switch is located in the overhead
console.
Pressing the switch turns both the front and
rear parking aids on or off. The switch warning
indicator will come on when the system is
turned on. A switch is not provided when only
a rear parking aid is fitted.
Note: The front parking aid will also operate
when reverse gear is selected.
The front parking aid provides an audible
proximity warning when driving forwards or
reversing.
The front and rear sensors only operate within
a fixed speed range in forward gears and are
not effective when moving forwards above
15 km/h (9 mph). Objects are detected within the approximate
operating range from the
front of the vehicle,
as shown in the illustration above:
1. 600 mm (24 inches).
2. 1800 mm (71 inches).
3. 800 mm (31 inches).
If an obstacle is detected at the front or rear of
the vehicle, a warning tone will be heard from
the front or rear speaker respectively.
Note: The outer rear sensors ( 1) will show
visual detection on the touch-screen, before
the audible warning is given.
The warning tone increa ses in rate as the
vehicle approaches the obstacle.
CAUTION
The parking aid system automatically
switches off when the vehicle is moving
above 15 km/h (9 mph) in D, and will need to
be reselected when moving below 15 km/h
(9 mph).

The front or rear warning tone will become
continuous when the obstacle is detected at or
within 300 mm (12 inches) from the vehicle.
Note: The outer front and rear sensors will
switch off if the distance to an object increases
or remains constant for 3 seconds. The
sensors will reactivate automatically if a new
object is detected with in the operating range,
or if the distance to the original object reduces.
Rear fitted accessories
Particular care must be taken when reversing
with rear fitted accessories e.g. bicycle carrier,
as the rear park assist will only indicate the
distance from the bumper to the obstacle.
Cleaning the sensors
Do not clean the sensors with abrasive or sharp
objects or materials.
For reliable operation, th e sensors in the front
and rear bumpers should be kept free from ice,
frost and grime.
When using a high pressure spray the sensors
should only be sprayed br iefly and not from a
distance of less than 200 mm (8 inches).
System fault
If the system has a fault when engaging reverse
gear or turning on the ignition, then a single,
three second tone will be heard (only once per
ignition cycle) and a pop-up warning will
appear on the touch-scre en. If both front and
rear parking aids are fitted, the warning
indicator in the parking aid switch will flash for
three seconds and then switch off, if a fault is
detected.
If a fault is detected, the system is
automatically disabled.
The parking aid may sound spurious tones if it
detects a frequency tone using the same band
as the sensors (e.g. air brakes).
