Adaptive cruise control (ACC)

ADVANCED EMERGENCY BRAKE
ASSIST
On vehicles fitted with Advanced Emergency
Brake Assist, brake response is improved
during emergency braking when a moving
vehicle is detected close ahead.
Advanced Emergency Brake Assist activates If
the risk of collision increases after the
FORWARD ALERT warning is displayed.
See FORWARD ALERT FUNCTION (page 164).
The brakes are automatica lly applied gently in
preparation for rapid braking (which may be
noticeable). If the brake pedal is then pressed
quickly, then braking is implemented fully,
even if the pressure on the pedal is light.
See HINTS ON DRIVING WITH ABS
(page 144).
Advanced Emergency Brake Assist is available
at speeds above approximately 7 km/h (5 mph)
and will function even if Forward Alert and
Adaptive Cruise Control are switched off. A
fault with the system will be indicated by the
warning FORWARD ALER T UNAVAILABLE
appearing in the mess age centre. Advanced
Emergency Brake Assist will not be available
until the fault is rectified.
WARNING
Advanced Emergency Brake Assist, is
an additional safety system and is not
intended to relieve the driver of the
responsibility for exer cising due care and
attention when driving.
CAUTION
The system may not react to slow
moving vehicles and will not react to
stationary vehicles or vehicles not
travelling in the same direction as your vehicle.
Advanced Emergency Brake Assist can
only improve braking performance if the
driver applies the brakes.
Warnings may not appear if the distance
to the vehicle ahead is very small or if
steering wheel and pedal movements
are large (e.g. to avoid a collision).
Advanced Emergency Brake Assist
utilises the same radar sensor as
Adaptive Cruise Control and Forward
Alert - the same limita tions of performance
apply.

Automatic speed limiter (ASL)

PRINCIPLE OF OPERATION
ASL can be used in a situation where varying
vehicle speed is likely but a maximum speed
must not be exceeded. For example, where a
local speed limit is 80 km/h (50 mph), the set
speed could be at that limit or just under.
If ASL is not selected, cr uise control is always
available by simply rotating the thumb wheel
on the right-hand side of the steering wheel to
set a cruising speed. The ASL button allows the
driver to select betwee n cruise control and the
automatic speed limiter. The ASL can be set to
any speed between 30 km/h (18 mph) and 240
km/h (150 mph).
Note: Although ASL only operates at speeds
between 30 km/h (18 mph) and 240 km/h (150
mph), the maximum speed can be set when the
vehicle is stationary.
When ASL is selected, the warning indicator in
the instrument panel will illuminate. When the
ASL button is pressed ag ain, the light will
extinguish, ASL will be cancelled and cruise
control will be available again.
USING THE ASL
Setting a speed limit
• Press the ASL button.
• Use the thumb wheel ( 1) to set the
required speed. The message centre
display in the instru ment panel will show
the selected speed.
• The set speed can be adjusted at any time
by rotating the thumb wheel (1).
WARNINGS
Automatic Speed Limiter (ASL) set
speeds must be within local speed
restriction limits. The driver must
always ensure that a safe speed is set, taking
into account the prevailing traffic and road
conditions.
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set speed limit. This
is because engine br aking is unable to
maintain or reduce the vehicle speed. Driver
intervention may be required.

Note: The message is also displayed at other
times as an information display.
When ASL is selected and a set speed inserted,
the engine will respond normally up to the set
speed. Further accelerator pedal pressure will
not increase the vehicle speed beyond your set
speed, unless kickdown is initiated, in which
case ASL will be suspended.
Suspending ASL
ASL can be suspended by pressing the
CANCEL button ( 3). Applying sudden, rapid
acceleration (kickdown) will also suspend ASL.
Resuming ASL
If ASL has been suspended, it can be reinstated
with a single press of the RESUME button (2),
however, ASL will only reinstate if the vehicle
speed is less than the current speed set in
memory and greater than 30 km/h (18 mph).
The message centre will display an appropriate
message if the vehicle speed is too fast to
resume ASL.
Exceeding the set speed
If the set speed is exceeded, e.g. on a steep
downhill section, th e message centre will
display an appropriate message along with an
amber warning indicator. There are three categor
ies of over limit
displays:
• If the set speed is exceeded by up to 3
km/h (1.8 mph), the message centre will
display the message along with an amber
warning indicator.
• If the set speed is exceeded by more than
7 km/h (4 mph), the message centre will
display the message along with a flashing
red warning indicator.
• If the set speed is exceeded by more than
7 km/h (4 mph) for a duration of four
seconds, the message centre will display
the message along with a flashing red
warning indicator and an audible warning
tone.
Use your brakes to rectify the situation.
ASL unavailable
If ASL is not available due to a fault, the
message centre will display an appropriate
message along with an amber warning
indicator.
The message and warning indicator will display
when the driver attempts to use ASL.
When the ignition is switched off, ASL is
deactivated and any set speed is deleted from
memory.

Driving dynamics

TracDSC
TracDSC is an alternative setting of DSC with
reduced system interventions. With TracDSC
engaged, traction may be somewhat increased,
although stability may be reduced compared to
normal DSC. TracDSC is intended for use only
on dry tarmac, by suitably experienced drivers
and should not be select ed for other surfaces
or by drivers with insufficient skill and training
to operate the vehicle safely with the TracDSC
function engaged.
The less restrictive TracDSC setting may be
preferred, for example, by expert drivers
engaged in high performance driving on dry
Tarmac surfaces such as tracks and circuits.
Switching between DSC and Trac DSC
• Press and hold the DSC switch for less
than 10 seconds.
• The message centre will temporarily
display either Trac DSC or DSC ON.
• The warning indicator in the instrument
panel will illuminate while Trac DSC is
selected.
• The warning indicator will flash when DSC
or Trac DSC is active.
Note: If cruise control is engaged, it will
automatically disengage if stability control
activates.
Switching between DSC OFF and ON
Switching DSC OFF
• Press and hold the DSC switch for more
than 10 seconds.
• The message centre will display DSC OFF
and a short warning chime will sound.
• The warning indicator in the instrument
panel will illuminate.
Switching DSC ON
If DSC is OFF:
• Press and release the DSC switch.
• The DSC system will switch on, the
message centre will temporarily display
DSC ON .
• The warning indicator in the instrument
panel will be extinguished.
Note: Switching the engine off and then on
again, will always revert DSC status to DSC ON,
regardless of which Ja guarDrive Control mode
is selected.
WARNING
Vehicle safety may be reduced by
inappropriate use of TracDSC.
TracDSC should only be used in
suitable conditions.

Driving dynamics
172

Note: In rare circumstances, when TracDSC is
selected or DSC is o ff, high acceleration on
rough roads may cause DSC to switch back on.
This prevents high loads on the vehicle
driveline. DSC will su bsequently remain on,
unless TracDSC is selected or DSC is switched
off manually.
Stability control indicator
If there is a fault, the warning
indicator will ill uminate in the
instrument panel and the message
centre will display DSC NOT AVAILABLE with
an amber backlight.
It is safe to drive the vehicle, but the DSC
system will not activa te under wheel spin or
slide conditions. You should seek qualified
assistance as soon as possible.
Adaptive dynamics
(Supercharged vehicles only)
Jaguar Adaptive dy namics continuously
monitors the road a nd driver inputs and
optimises the vehicle suspension settings for
ride comfort and control.
The adaptive dynamics system is linked to
Dynamic mode, modifying the suspension
settings for a more sporting character.
If the message centre displays the message
ADAPTIVE DYNAMICS FAULT , a fault has been
detected in the adaptive dynamics system.
Seek qualified assistan ce as soon as possible.
Active Differential Control (E-diff)
(Supercharged vehicles only)
The E-diff improves trac tion when one driven
wheel has more grip than the other. This
improves progress out of corners and on
patchy or uneven surfaces. The E-diff can also
increase stability in oversteer situations,
depending on road c onditions and driver
inputs. Settings for the E-diff are made automatically,
without the need for driver selection.
If there is a fault with the E-diff system, the
message centre will display
EDIFF SYSTEM
FAULT . If DSC is off, then TracDSC will be
selected automatically. The driver can still
switch between DSC mode s, as normal and the
vehicle is safe to dr ive, but seek qualified
assistance as soon as possible.
Note: If the E-diff is active continuously for an
extended period (e.g. on a patchy surface with
DSC off) then the E-diff may be temporarily
deactivated to prevent ov erheating. If DSC is
off, then TracDSC will be selected
automatically. The mess age centre will display
EDIFF NOT AVAILABLE . The driver can still
switch between DSC modes as normal and the
E-diff will become availa ble again automatically
when it has cool ed sufficiently.

SAFETY PRECAUTIONSFUEL QUALITY
Water in fuel
Petrol engined vehicles
WARNINGS
Petroleum gasses are highly
flammable, have a low flash point,
and are explosive, especially in
confined spaces. Avoid exposing the gasses to
any potential sources of ignition as the
resulting fire and expl osion may cause serious
injuries and/or death.
Only use containe rs specifically
designed for carrying fuel and always
remove them from the vehicle to fill
them. Failure to do so may result in spillage,
and cause a fire.
Switch off the engine when refuelling,
as it is both a source of extreme
temperatures, and electrical sparks.
The resulting fire a nd explosion may cause
serious injury and death.
Switch off any personal electronic
devices such as mobile phones, or
music players. They have the
potential to cause electrical sparks. The
resulting fire and expl osion may cause serious
injury and death.
Do not smoke, use a naked flame, or
cause sparks. The resulting fire and
explosion may cause serious injury
and death.
Do not overfill the fuel tank.
Overfilling may cause spillage when
the vehicle is driven. Spillage may
also occur if the fuel expands in high ambient
temperatures.
Any modifications to the fuel system
not specifically designed for this
Jaguar are prohibited. Such
modifications in some circumstances, could
result in a fire. All se rvice actions should be
entrusted to a Dealer /Authorised Repairer.The presence of any unusual fumes
(e.g. petrol or exhaust fumes) in the
passenger compartment and/or
luggage compartment, should be corrected
immediately by a Dealer /Authorised Repairer.
If you must drive unde r these conditions, do
so only with all windows fully open.
CAUTIONS
If the warning WATER IN FUEL is
displayed in the message centre, an
excessive amount of wate r has collected in the
fuel filter bowl. Seek assistance from a Jaguar
Dealer/Authorised Repairer to have the filter
drained, as soon as possible.
CAUTIONS
Do not use leaded fuels, lead substitutes
or fuel additives. Doing so can cause
damage to the engine, fuel and emission
control systems.
Only use high quality petrol, as using
lower quality fuels ca n cause damage to
the engine, fuel and emission control systems.
Fuel system cleaning agents should not
be used, unless a pproved by Jaguar.
Unapproved products may be harmful to fuel
system components on your vehicle.
It is the driver’s resp onsibility to fill the
vehicle with the correct fuel. If the
vehicle is filled with the wrong type of fuel, do
not start the engine. Call for Roadside
Assistance.
