Do not allow the vehicle to remain
stationary with a drive gear selected and
the engine running . Always select P or
N if the engine is to idle for a prolonged
period.
ROTARY GEAR SELECTOR
The JaguarDrive selector elevates out of the
centre console when the engine is started, in
readiness for gear selection
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.
In the event of a vehicle breakdown, the
transmission will automatically select P. This
prevents the vehicle from being towed on all
four wheels. Therefore, vehicle recovery
should only be undertaken by suitably qualified
personnel.
IF THE SELECTOR FAILS TO ELEVATE
If the JaguarDrive selector is obstructed
remove the obstruction 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. P should be selected manually.
The fault should be re ctified by a Dealer/
Authorised Repairer at the earliest opportunity.
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.
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.
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.
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 event of an electrical or mechanical
failure, transmission ope ration will be limited.
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 ignition 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 st ill unable to select the
requested gear, contact your Dealer/
Authorised Repairer.

Stability control
83
Stability controlWINTER MODE
Winter mode optimises stability of the vehicle
to suit slippery conditions, when grip is
reduced. This helps the vehicle to perform in a
more gentle and controlled manner, to avoid
skidding, allowing more confident progress
under adverse conditions.
Note: Winter mode cannot be active at the
same time as Dynamic m ode. Winter mode will
remain selected indefinitely, even after the
ignition is switched off. Winter mode must be
deselected if no longer required.
DYNAMIC MODE
Note: When the transmission is set to
permanent manual mode and Dynamic mode is
selected, transmission upshifts are fully
controlled by the driver . The transmission will
not change up automatically, even when the rev
limit is reached (the ge ar position indicator in
the message centre will gl ow amber, to indicate
that the next gear should be selected).
Note: Dynamic mode cannot be active at the
same time as Winter mode. Dynamic mode will
remain selected for approximately six hours
after the ignition is switched off, after which
point it will need to be reselected if required.
TRACDSC
Vehicle safety may be reduced by
inappropriate use of of Trac DSC. Trac
DSC should only be used in suitable
conditions.
Trac DSC is an alternative setting of DSC, with
reduced system interventions. With Trac DSC
engaged, traction may be increased, although
stability may be reduced compared to normal
DSC. Trac DSC is intended for use only on dry
tarmac, by suitably experienced drivers. Trac
DSC should not be selected for other surfaces
or by drivers with insuff icient skill and training
to operate the vehicle safely with Trac DSC
function engaged.
Press to operate. Designed for use
in slippery conditions, when
active, Winter mode selects 2nd
gear for driving away on level
ground (no incline), softens the
responsiveness of the engine and
modifies the gear change strategy.
This helps ensure that optimum
traction is maintained.
Press to operate. Dynamic mode
co-ordinates the vehicle's control
systems to deliver a high
performance driving experience.
This setting enhances key vehicle
systems so that the vehicle's full
potential can be exploited. The
vehicle's responses are aimed at
involving the driver more in
focused and purposeful driving.

Brakes
87
BrakesIMPORTANT INFORMATION
Do not rest your foot on the brake
pedal whilst the vehicle is in motion.
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 wi th the engine off,
but far more pressure will be required
to operate them.
If the red brake warning lamp
illuminates, safely bring the vehicle to
a stop, as quickly as possible and
seek qualified assistance.
Never place non-approved floor
matting or any other obstructions
under the brake pedal. This restricts
pedal travel and braking efficiency.
Driving through heavy rain or water can have
an adverse effect on braking efficiency. Under
such circumstances, it is recommended that
you lightly apply the brak es intermittently to
dry the brakes.
BRAKE WARNING LAMPS
Note: This warning lamp will also illuminate if
there is a fault with the parking brake. See 88,
ELECTRIC PARKIN G BRAKE (EPB).
ELECTRONIC BRAKE FORCE
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 heavily laden.
A fault with the EBD system is indicated by the
red brake warning lamp and the message EBD
FAULT . The braking system will still operate,
but without EBD assist ance. Seek qualified
assistance to have the fault rectified.
EMERGENCY BRAKE ASSIST (EBA)
The EBA system measures the rate at which the
brake pressure increases. If the system detects
an emergency braki ng situation, EBA
automatically initiates fu ll braking effect. This
can reduce stopping distances in critical
situations.
A fault with the EBA system is indicated by the
brake warning lamp illuminating and
Emergency Brake Assist Not Available
displaying in the message centre. The braking
system will still func tion, but without EBA
assistance. Seek qualified assistance to have
the fault rectified.
EMERGENCY STOP SIGNAL (ESS)
ESS (Emergency Stop Signal) automatically
activates the hazard warning lights during
emergency braking to warn other road users
and reduce the risk of a collision.
If the parking brake
is released and
this red warning lamp illuminates
while driving and/or the message
Brake Fluid Low is displayed in the
message centre, check the brake
fluid level at the earliest
opportunity and top-up as
required.
If this amber warning lamp
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.

The red brake warning lamp on the instrument
panel will illuminate.
The Drive Away Release feature allows the
parking brake to release automatically as the
vehicle is driven away.
The warning lamp will remain on briefly if the
parking brake is applied when the ignition
system is reverted to convenience mode.
If a fault in the system is detected, the amber
brake warning lamp will illuminate and PARK
BRAKE FAULT or CANNOT APPLY PARK
BRAKE will be displayed in the message centre.
Seek qualified assistan ce as soon as possible. If the battery has been discharged or
disconnected,
APPLY FOOT AND PARK BRAKE
will be displayed in the message centre when
the ignition is next switched on. Depress the
foot brake and pull the parking brake switch up
to apply the parking brake. This is required to
reset the parking brake system. The parking
brake will now f unction correctly.
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.
If the parking brake is inadvertently applied
when the vehicle is moving at above 3 km/h
(1.8 mph), PARK BRAKE APPLIED is displayed
in the message centre, the warning indicator in
the instrument panel will illuminate and a
warning chime will sound.
If the parking brake is a pplied whilst the vehicle
is moving, releasing th e switch will disengage
the parking brake. The parking brake cannot be
applied when the vehicle is moving, if the
accelerator pedal is pressed.
Note: If the vehicle is in motion, the parking
brake should only be used as an emergency

Cruise control
94
Cruise controlUSING CRUISE CONTROL
The cruise (speed) contro l system can be used
by the driver to maintain a selected vehicle
speed above 30 km/h (18 mph).
1. SET (+ / - ) : Roll upwards to engage cruise
control. Roll up or down to increase or
decrease the set cruising speed.
2. CANCEL : Press to disengage cruise
control. The set sp eed memory will be
retained.
3. RESUME : Resumes the cruise control set
speed after it has been disengaged.
SETTING VEHICLE SPEED
Only use cruise control when
conditions are favourable (e.g.
straight, dry, open roads with light
traffic).
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set cruising speed.
This is because eng ine braking is
unable to maintain or reduce the
vehicle speed. Driver intervention
may be required.
When you are travelling at the speed you
require press the set button.
Cruise control will enga ge and maintain the set
speed and you can remove your foot from the
accelerator pedal. Note:
Cruise control w ill automatically
disengage when the brake pedal is pressed or
when the vehicle speed falls below 30 km/h
(18 mph).
CHANGING THE CRUISE SPEED
There are two ways to change the set speed:
• Accelerate or decele rate to the desired
speed then roll the SET control upwards.
• Increase or decrease the speed by rolling
the SET control up or down until the
desired speed is obtained.
Note: The set speed can be increased or
decreased in steps of 2 km/h (1 mph), by
rolling the SET control up or down briefly until
the desired spee d is obtained.
RESUMING THE SET SPEED
If the vehicle is accelerated above the set
speed, then the set speed will be resumed
when the accelerator pedal is released.
If the CANCEL button ( 2) or the brake pedal is
pressed, the cruise cont rol will disengage but
the set speed memory will be retained. Press
RESUME (3) and the vehicle will return to the
set speed.
Note: Cruise control will not resume at speeds
below 30 km/h (18 mph).
RESUME should only be used if the
driver is aware of the set speed and
intends to return to it.
It is not recomme nded to resume set
speed when a low gear is selected as
excessive engine speeds will occur.

RESUMING THE SPEED AND
FOLLOW MODE
RESUME should only be used if the
driver is aware of the set speed and
intends to return to it.
By pressing the RESUME button after ACC has
been cancelled, for example, after braking, the
ACC will become active again provided that the
set speed memory has not been erased. The
original set speed will be resumed (unless a
vehicle ahead causes the follow mode to
become active) and the set speed will be
displayed in the message centre for four
seconds.
HINTS ON DRIVING WITH ACC
The system acts by regulating the speed of the
vehicle using engine c ontrol and the brakes.
Gear changes may occur in response to
deceleration or accele ration whilst in ACC.
ACC is not a collision avoidance system.
However, during some situations the system
may provide the driver with an indication that
intervention is required.
An audible alarm will sound, accompanied by
the message DRIVER INTERVENE if the ACC
detects:
• A failure has occurred whilst the system is
active
• That using maximum ACC braking only is
not sufficient.
Note: ACC operates when the gear selector
lever is in position S or D.
Note: When engaged, the accelerator pedal
rests in the raised position. Fully release the
pedal to allow normal ACC operation.
Note: When braking is applied by the ACC, the
vehicle brake lamps will be switched on
although the brake pedal will not move.
DETECTION BEAM ISSUES
Detection issues can occur:
1. When driving on a different line to the
vehicle in front.
2. When a vehicle edges into your lane. The
vehicle will only be detected once it has
moved fully into your lane.
3. There may be issues with the detection of
vehicles in front when going into and
coming out of a bend.
In these cases ACC may brake late or
unexpectedly. The driver should stay alert and
intervene if necessary.
