Park Distance Control
Caution: It remains the driver’s
responsibility to detect obstacles and
estimate the car’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.
Park distance control is always
automatically switched on when the
ignition is turned on.
Caution:
1. If, for example, you are driving into a confined space such as a
home garage, the outer sensors
will detect the side walls and after
3 seconds will switch the tone off.
However, as movement
continues, the inner sensors will
eventually detect the rear wall
and will start the tone again.
2. The sensors are not active when the gear selector is in neutral,
therefore, take care if moving the
vehicle as the tone will not be
heard.
3. Do not clean the sensors with abrasive or sharp objects. Note:
1. For reliable operation, the sensors in
the front (if fitted) and rear bumpers
should be kept free from frost, ice and
grime.
2. When using a high pressure spray the sensors should only be sprayed briefly
and at least 8 inches (20 cm) distance
from the sensors.
3. The front parking aid may sound spurious tones if it detects a frequency
tone using the same band as the
sensors.
Rear Park Distance Control
When reverse gear is selected and
ignition is on, rear park distance control
automatically provides an audible
proximity warning (to the nearest
detected obstacle) when reversing the
vehicle if obstacles are detected within
the operating range, shown in the
illustration above (between
approximately 24 inches [60 cm] ( A) and
63 inches [160 cm] ( B).

4-36 On the Road
Front and Rear Park Distance
Control
When both front and rear park distance
control are fitted, a switch is located in
the overhead console.
Pressing the switch turns front and rear
park distance control on or off together.
The switch integral warning lamp will
come on when the system is turned off or
if a fault is detected in the system.
A switch is not provided when only rear
park distance control is fitted.
Note: The front park distance control will
also operate when reverse gear is
selected. Front park distance control provides an
audible proximity warning when driving
forwards if objects are detected within
the operating range shown in the
illustration above (between
approximately 24 inches [60 cm] (
A) and
31 inches [80 cm] (C ) to the front of the
vehicle). The front sensors only operate
within a fixed speed range in forward
gears and are not effective when moving
forwards above 9mph (15km/h) or when
slowing down until below 4½ mph
(7 km/h).
If an obstacle is detected at the front or
rear of the vehicle, a beep tone will be
heard from the front or rear speaker
respectively, which increases in rate as
the vehicle approaches the obstacle. The front or rear park distance control
beep will become co
ntinuous when the
obstacle is detected at or within
12 inches (30 cm) from the rear or
approximate 10 inches (25 cm) from the
front of the vehicle.
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,
if fitted, the switch lamp will come on.
The system is automatically disabled
when a fault is detected.

4-46 On the Road
Dynamic Stability
Control (DSC)
Unless it has been switched off, dynamic
stability control is operational whenever
the engine is running. If the system is
operating, the warning light in the
instrument cluster will flash.
The DSC system controls the anti-lock
braking system (ABS), traction control
and yaw control of the vehicle.Yaw control determines the vehicle’s
direction relative to
the driver’s inputs
(sideslip and under/ov ersteer). It applies
braking pressure to individual wheels if
excessive variation is detected.
This ensures that the vehicle follows the
driver’s intended direction of travel.
Traction control will intervene to reduce
wheel spin, by automatically reducing the
power output from the engine and
applying braking to individual wheels.
This improves acceleration, particularly
on surfaces with uneven friction,
for example, one wheel on ice the other
on tarmac.
ABS helps to prevent the road wheels
from locking and skidding during
emergency braking.
When the system is operating,
the warning light in the instrument
cluster will flash.
The dynamic stability control system can
be switched OFF by pressing the switch
on the centre console switchpack.
The warning light in the instrument
cluster will remain on and a message will
be shown to indicate that the system has
been switched OFF. If the switch is
pressed again the system will switch ON. Note:
If cruise control is engaged it will
automatically disengage if stability control
activates.
A system malfunction is indicated by the
message:
DSC NOT AVAILABLE
Warning light: Amber .
and the instrument cluster DSC warning
light will be lit.
It is safe to drive the vehicle but the
system may not activate under wheel spin
or slide conditions. Report the fault to a
Jaguar Retailer as soon as possible.
!WARNING:
1. The fact that the vehicle is fitted with Dynamic Stability Control
must never allow th e driver to be
tempted into taking risks which
could affect his/her safety or that
of other road users. In all cases it
remains the driver’s responsibility
to drive safely according to the
prevailing conditions.
2. It is recommended that when using snow chains, DSC should be
switched OFF.

On the Road 4 - 49
Cruise (Speed) Control
The cruise (speed) control system can be
used by the driver to maintain a selected
vehicle speed above 17.5 mph (28 km/h)
without the driver having to use the
accelerator.
Switches on the steering wheel allow the
driver manual control of the system.
Brake operation also influences the cruise
control system. (
A ) – RESUME to resume the set speed
retained in memory.
( B ) – SET to set the speed or increase/
decrease the set speed when the speed
has been set.
( C ) – CANCEL cancels cruise control but
retains the set speed in memory.
Setting the Vehicle Speed
!WARNING:
Only use cruise control when
conditions are favourable,
for example, straight, dry, open roads
with light traffic.
When you are travelling at the speed you
require, which must be above 17.5 mph
(28 km/h), press the SET button.
Cruise control will engage and maintain
the set speed and you can remove your
foot from the accelerator pedal.
Note: Cruise control will automatically
disengage when the brake pedal is pressed
or when the vehicle speed falls below
16 mph (26 km/h).
Changing the Set Speed
There are three ways to change the set
speed:
1. Accelerate or decelerate to the desired speed then press the SET (+) button.
2. Increase or decrease the speed by pressing and holding either SET (+)
or (–) until the desired speed is
obtained, then release the switch.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing either the SET (+) or (–) until
the desired speed 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 CANCEL is pressed, or the brake pedal
is pressed, the cruise control will
disengage but the set speed memory will
be retained. Press RESUME and the
vehicle will return to the set speed.
Note: Cruise control will not resume at
speeds below 17.5 mph (28 km/h).
RESUME will not operate if the ignition
has been turned off.

On the Road 4 - 53
When a vehicle ahead enters the same
lane or a slower vehicle is ahead in the
same lane, the vehicle speed will be
adjusted automatically until the gap to
the vehicle ahead corresponds to the
preset gap. The vehicle is now in ‘follow
mode’.The warning light in the
instrument cluster will be
illuminated,
and the message centre
will display the gap set.
The vehicle will then maintain the
constant time gap to the vehicle ahead
until:
• The vehicle ahead accelerates to a speed above the set speed.
• The vehicle ahead moves out of lane or out of view.
• The vehicle ahead slows so that ‘low speed automatic switch off’ occurs.
• A new gap distance is set.
If necessary, the vehicle brakes will be
automatically applied to slow the vehicle
to maintain the gap to the vehicle in
front. The maximum braking which is applied
by the ACC system is limited and can be
overridden by the driver applying the
brakes, if required.
Note:
Driver braking will cancel adaptive
cruise control.
If the ACC system predicts that its
maximum braking level will not be
sufficient, then an audible warning will
sound while the ACC continues to brake.
This is accompanied by a red warning
light and ‘DRIVER INTERVENE’ will be
displayed on the message centre.
The driver should take IMMEDIATE
action.
When in follow mode the vehicle will
automatically return to the set speed
when the road ahead is clear, for instance
when:
• The vehicle in front accelerates or changes lane.
• The driver changes lane to either side or enters an exit lane.
The driver should intervene if
appropriate.
Low speed automatic switch off
If the speed of the vehicle decreases
below 18 mph (30 km/h), the ACC system
will be automatically switched OFF and
the instrument warning lamp will go out. If the brakes were
being applied by the
ACC system, they will be slowly released.
This will be accompanied by an audible
warning, a red warning light and ‘DRIVER
INTERVENE’ will be displayed on the
message centre. The driver must take
control.
Overriding the set speed/follow mode
!WARNING:
Whenever the driver is overriding the
ACC by depressing the accelerator
pedal, the ACC will not automatically
apply the brakes to maintain
separation from any vehicle ahead.
The set speed and gap can be overridden
by pressing the accelerator pedal when
cruising at constant speed or in follow
mode. If the vehicle is in follow mode,
the instrument warning lamp will go out
when the ACC is overridden by the driver
using the accelera tor and ‘CRUISE
OVERRIDE’ will be displayed on the
message centre. When the accelerator is
released the ACC function will operate
again and vehicle speed will decrease to
the set speed, or a lower speed if follow
mode is active.
GAP

4-54 On the Road
Changing the set speed
There are three ways to change the set
speed:
1. Accelerate or brake to the required speed and press the ‘SET +’ button.
2. Increase or decrease the speed by pressing and holding either the
‘SET +’ or ‘–’ button until the required
set speed is shown on the message
centre. The vehicle speed will
gradually change to the selected
speed.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing the ‘SET +’ or ‘–’ button.
ACC operates between approximately
20 mph and 110 mph (34 km/h and
180 km/h) dependent on the country
specification.
Set speeds outside this range will not be
captured.
The ACC may apply the brakes to slow
down the vehicle to the new set speed.
The new set speed will be displayed on
the message centre for four seconds after
it has been changed. Changing the gap
The gap from the vehicle ahead can be
decreased or increased by pressing the
gap setting rocker switch on the steering
wheel. Four gaps are available and the
selected gap setting will be displayed on
the message centre when the rocker
switch is pressed. After the ignition is
switched ON the default gap will be
automatically selected ready for ACC
operation.
Note:
It is the driver’s responsibility to
select a gap appropriate to the driving
conditions, and in accordance with
national driving regulations.
ACC automatic switch off
Adaptive cruise control will disengage,
but not clear the memory when:
• The CANCEL button is pressed.
• The brake pedal is pressed.
• The vehicle speed falls below 18 mph (30 km/h).
• Neutral, Park or Reverse gear positions are selected.
• The parkbrake is applied.
• DSC is activated. Adaptive cruise control will disengage,
and clear the memory when:
• The ignition switch is set to
position ‘0’.
• Maximum vehicle speed is reached.
• A fault occurs in the ACC system.
Resuming the set speed/follow mode
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 set
speed will be displayed for four seconds
and the original set speed will be
resumed, unless a vehicle ahead causes
the follow mode to become active.
Caution: ‘RESUME’ should only be
used if the driver is aware of the set
speed and intends to return to it.

On the Road 4 - 55
Forward alert
Limited detection and warning of objects
ahead is provided during ACC operation
by the ACC ‘DRIVER INTERVENE’
warning.
The forward alert feature additionally
provides warnings whilst ACC is not
engaged, if an object is detected close
ahead then a warning tone and message
will be issued. The brakes will not be
applied.
This additional feature may be switched
on or off using the forward alert switch in
the lower outboard knee bolster
switchpack. When the indicator lamp in
the switch is on, forward alert is active.The sensitivity of the warning may be
changed:
• Pressing the gap decrease button
when ACC is disengaged displays and
then decreases the sensitivity of the
alert.
• Pressing the gap increase button displays and then increases the
sensitivity of the alert.
Both of these are accompanied by the
FORWARD ALERT message on
the message centre.
ACC failure
If a fault occurs during operation of the
system in cruise or follow modes,
the ACC system will switch OFF and
cannot be used until the fault is cleared.
A red warning light and the message
‘DRIVER INTERVENE’ appear briefly, and
are then replaced by an amber warning
light and the message ‘CRUISE NOT
AVAILABLE’.
If failure of the ACC or any related system
occurs at any other time an amber
warning light will be displayed
accompanied by th e message ‘CRUISE
NOT AVAILABLE’. It will not be possible
to activate the ACC system in any mode. Accumulations of dirt, snow or ice on the
on the sensor or cover may inhibit ACC
operation. Fitting of a vehicle front
protector or metallis
ed badges may also
affect ACC operation.
If this occurs in ACC cruise/follow mode,
the red warning light is displayed,
the audible alarm sounds and the
message ‘DRIVER INTERVENE’ appears
briefly. These warnings are then replaced
by the amber warning light and the
message ‘ACC SENSOR BLOCKED’ is
displayed. The system is no longer active.
Clearing the obstruction allows the
system to return to normal operation.
If the obstruction is present when ACC is
inactive, e.g. on initial starting or with the
ACC system switched off, the amber
warning light will be displayed with the
message ‘ACC SENSOR BLOCKED’.
Tyres other than those recommended
may have different sizes. This can affect
the correct operation of the ACC.

General Driving
Information
!WARNING:
Ensure the parkbrake is on and the
automatic gear selector is in
position ‘P’ or ‘N’ before attempting
to start the engine.
Before driving off, check the gauges and
warning lights and messages. Take special
note of any warning light that is on.
Seat belts are provided for your safety
and it is unwise, and in certain countries
illegal, to commence any journey,
however short, without wearing them.
Warming Up
Do not operate the en gine at high speed
when first started but allow time for the
engine to warm up and the oil to
circulate.
Engine Braking On Downhill
Gradients
When driving on mountain roads with
long downhill gradients it is advisable to
select a low gear.
Running-in
Apart from a few precautionary
recommendations, there are no strict
‘running-in’ procedures for this vehicle.
By observing the following advisory notes
you will ensure maximum engine,
transmission and brake life for your
vehicle:
1. Allow the engine to warm up thoroughly before operating at engine
speeds over 3500 rev/min.
2. Vary the speed frequently.
3. From 940 miles (1500 kilometres) onwards, gradually increase
performance of the vehicle up to the
permitted maximum speed, where
road conditions permit. Running-in for brakes
To ensure that the brake pads can
‘bed-in’ evenly and reach their optimum
wear and performance condition, usually
within 300 miles (480 kilometres),
the following points are recommended.
1. Where possible, avoid heavy braking
or rough usage of the brakes as this
can result in damage being caused to
the brake pads and discs.
2. Avoid prolonged use of the brakes, for example, when descending severe
gradients.
3. Frequent light application of the brakes is desirable. This helps to fully
‘bed-in’ the brake pads before the
normal running-in period is
completed and the vehicle is operated
at high speeds, when maximum brake
efficiency will be required.
The above equally applies when new
discs or pads have been fitted.
