2009 JAGUAR XF ignition

Adaptive cruise control (ACC)
162

Automatic low speed switch off
If the speed of the vehicle decreases below
30 km/h (18 mph), the ACC system will be
automatically switched off and the instrument
warning indicator 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, and DRIVER INTERVENE will be
displayed on the message centre. The driver
must take control.
Automatic switch off
ACC will disengage, but not clear the memory
when;
• the CANCEL button ( 3) is pressed
• the brake pedal is pressed
• Neutral ( N), Park ( P) or Reverse ( R) gear
positions are selected
• Dynamic Stability Control activates.
ACC will disengage, and clear the memory
when;
• the ignition system is switched off
• maximum vehicle speed is reached
• a fault occurs in the ACC system.
Resuming the speed and follow mode
By pressing the RESUME button (4) 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 acceleration 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.
CAUTION
RESUME should only be used if the
driver is aware of the set speed and
intends to return to it.

Automatic speed limiter (ASL)
168

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

GENERAL INFORMATION
JaguarDrive Control
JaguarDrive Control is a selectable vehicle
optimisation system, designed to fine-tune the
driving characteristics of the vehicle by
accommodating different dr iving conditions or
driving styles.
The system allows the performance envelope
of the vehicle to be stretched and prevents the
necessity for a single, compromised
configuration for all conditions, thereby
increasing the vehicle's abilities.
The vehicle systems optimised by JaguarDrive
Control are:
• Engine management.
• Transmission management.
• Dynamic Stability Control and traction
control.
• Adaptive dynamics.
• Active Differential Control (E-diff) -
Supercharged vehicles only.
Note: Changing from one special mode to
another, will introduce noticeably different
vehicle responses. For example, the engine
revs produced by the accelerator position when
a special mode is not selected, may increase or
decrease when a mode is selected.
To familiarise y ourself with, and get the best
from, the JaguarDrive Control modes, you
should try out the mode s in circumstances
which are safe for you and other road users. 1.
Dynamic mode switch.
2. Winter mode switch.
3. DSC mode switch.
WINTER MODE
Press to operate. Designed for use
in slippery conditi ons, 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 ch ange strategy. This
ensures that optimum traction is maintained.
Winter mode optim ises stability of the vehicle
to suit slippery conditions, when grip is
reduced. The vehicle perfor ms 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 mode. Winter mode will
remain selected indefinite ly after the ignition is
switched off, until deselected by the driver.
WARNING
It remains the driver's responsibility
to drive safely, according to the
prevailing conditions and within the
law.

DYNAMIC MODE
(V8 petrol and diesel vehicles only)
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,
helping swift progress.
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
upshifts 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.
Note: Dynamic mode cannot be active at the
same time as Winter m ode. Dynamic mode will
remain selected for approximately six hours
after the ignition is swit ched off, after which
point it will need to be reselected if required.
STABILITY CONTROL
Dynamic Stability Control (DSC)
Dynamic Stability Contro l (DSC) is operational
whenever the engine is running, unless it has
been manually switched off. When the system
is operating, the warn ing indicator in the
instrument panel will flash.
The DSC system controls the Anti-lock Braking
System (ABS), traction control and yaw control
of the vehicle.
The DSC system assists the driver in retaining
directional control of th e vehicle in situations
where the vehicle is sliding (understeer or
oversteer). It must not encourage the driver to
drive beyond the limit of adhesion or at speeds
higher than those suitable for the prevailing
road and traffic conditions.
DSC applies braking pres sure to individual
wheels if excessive variation is detected. This
ensures that the vehicle follows the driver’s
intended direction of travel as closely as
possible.
Traction control will intervene to control 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
(e.g. one wheel on ice with another on tarmac).
Note: For recommended DSC mode selection,
refer to the JaguarDri ve Control scenarios
section in this handbook.
WARNING
The fact that the vehicle is fitted with
DSC, must never allow the driver to
be tempted into taking risks which
could affect his or her sa fety or that of other
road users. In all cases, it remains the driver’s
responsibility to drive sa fely according to the
prevailing conditions.

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.
WARNINGS

Fuel and refuelling

Sulphur content
In some countries diesel may contain higher
levers of Sulphur, wh ich could cause damage
to the vehicle, if in doubt contact a local
Dealer/Authorised Repairer for advice.
RUNNING OUT OF FUEL
Note: If the vehicle does run out of fuel, a
minimum of 4 litres (0.9 gallons) will be
required to restart the engine. The vehicle will
need to be driven 1.6-5 km (1-3 miles) in order
to reset the engine management and
monitoring systems.
Note: If the vehicle does run out of fuel,
seeking qualified assistance is advisable.
Diesel engines
Vehicles with diesel e ngines are equipped with
a system to prevent the fuel tank from
emptying completely. When the fuel reaches a
minimum level, the system will activate a
reduced power mode (i.e . the engine will not
run properly). This will be followed by the
engine stopping in a pproximately 1.6 km
(1 mile). This feature prevents the fuel system from
running dry, which could cause damage to the
vehicle. If the gauge indicates low fuel or the
warning indicator illumi
nates, the fuel tank
should be refuelled as soon as possible at the
next filling stat ion, with at least 4 litres (0.9
gallons) of fuel.
If the system protection function has activated,
the vehicle must firstly be refuelled, then
restarted using the following procedure:
1. With the brake pedal pressed, press and
hold the engine START/STOP button and
crank the engine for five seconds.
2. Release the START/STOP button.
3. With the brake pedal pressed, press and
release the START/STOP button to crank
the engine. The engine should start within
approximately five seconds.
Note: If the engine does not start, pause for ten
seconds with the ignition in convenience
mode, before re peating the procedure from the
beginning.
FUEL CUT-OFF
The fuel system cut-off forms part of the
Supplementary Restraint System (SRS) fitted
to your vehicle. Following an impact, and
depending on the severity , the fuel pump may
be switched off.
CAUTION
Your vehicle is fitted with a Diesel
Particulate Filter (DPF), the maximum
Sulphur content must not exceed 0.005%.
Using an incorrect fuel will cause serious
damage to the DPF. See DIESEL
PARTICULATE FILTER (DPF) (page 135).
CAUTION
Avoid running out of fuel. Doing so can
cause damage to th e vehicle's engine,
fuel and emission control systems.
CAUTION
Do not crank the engine for longer than
30 seconds, or damage to the fuel pump
may occur.
