2009 JAGUAR XF ECO mode

Transmission
140

Fast off
Activated when rapidly lifting off the
accelerator pedal and takes account of road
gradient. This feature inhibits up-shifts,
enhancing pe rformance.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Shift adapt under braking
Under braking, the transmission will vary the
down-shift point in proportion to braking effort
and road gradient. This feature works in
conjunction with the posit ive torque function,
resulting in a smoother down-shift.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Corner recognition
Inhibits up-shifts during cornering, to provide
improved vehicle balance.
Note: If Sport mode is selected, driver type
recognition will vary the activation of this
feature according to driving style.
Road gradient recognition
When the vehicle is being driven on an uphill
gradient, the transmission adapts the shift
pattern to make better use of engine power.
When driving on a long downhill gradient, the
transmission may automatically select a lower
gear, to increase engi ne braking. Selecting
Sport mode (S ) will increase the tendency of
the transmission to select a lower gear in these
conditions, further incr easing engine braking.
Note: It is also possible to manually select a
lower gear to increase e ngine braking via use of
the shift paddles.
Sport mode
To select Sport mode:
1. With the selector in D, push down on the
selector.
2. Rotate from D to S.
Note: When Sport mode is selected SPORT will
be displayed in the message centre, and the
selector indicator will illuminate.
Sport mode enhances th e responsiveness of
the transmission, to prov ide a sporting feel to
driving the vehicle. Sport mode is
recommended for over taking manoeuvres and
for when rapid progress is desired.
To return to automatic m ode move the selector
lever back to the D position. The D on the
selector display will illuminate to confirm that
automatic mode has been selected.

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.

Parking aid
148

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.

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.

Adaptive cruise control (ACC)

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.
ACC malfunction
If a malfunction occurs during operation of the
system in cruise or follow modes, the ACC
system will switch off a nd cannot be used until
the fault is cleared. The message DRIVER
INTERVENE appears briefly and is then
replaced by the message CRUISE NOT
AVAILABLE . If malfunction of the ACC or any
related system occurs at any other time, the
message CRUISE NOT AVAILABLE will be
displayed. It will not be possible to activate the
ACC system in any mode.
Accumulations of dirt, snow or ice on the
sensor or cover may inhibit ACC operation.
Fitting of a vehicle front protector or metallised
badges may also affect ACC operation.
The ACC system relies on its radar to detect
objects and constantly scans ahead. If the
radar detects no objects ahead in ACC or follow
mode , then the ACC will be deactivated, the
audible alarm sounds and the message
DRIVER INTERVENE displays briefly. The
message ACC SENSOR BLOCKED will then be
displayed.
The same messages may also be displayed
while driving on open roads with few objects
for the radar to detect.
Clearing the obstruction allows the system to
return to normal operation. If the obstruction is
present when ACC is inac tive, e.g. on initial
starting or with the ACC system switched off,
the message ACC SENSOR BLOCKED will be
displayed.
Tyres other than those recommended may
have different sizes. This can affect the correct
operation of the ACC.1

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.

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.
