Adaptive cruise control (ACC)
160

Setting the speed
Accelerate as normal until the required speed is
reached.
Rotate the speed adjustment control upwards
(+) to store the vehicle speed in the memory
and engage the system.
The set speed will be displayed on the message
centre (e.g. SETSPEED 80 KM/H (50 MPH) ).
Changing the speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed
then rotate the speed adjustment control
upwards ( +).
• Increase or decrease the speed by rotating
the speed adjustment control upwards ( +)
or downwards ( -), until the required set
speed is shown on the message centre.
The vehicle speed will gradually adjust to
the selected speed.
• Increase or decrease the speed in steps of
2 km/h (1 mph) by rotating the speed
adjustment control upwards (+) or
downwards ( -) briefly until the desired
speed is obtained.
ACC operates between approximately 30 km/h
and 180 km/h (18 mph and 112 mph)
dependent on the c ountry specification.
Set speeds outside th is 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
until ACC is cancelled.
Follow mode gap settings
Once a set speed has been selected, the driver
can release the accelerator and the set road
speed will be maintained.
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 default gap setting (gap level 3). The
vehicle is now in
follow mode.
The amber warning indicator in the
instrument panel will be
illuminated.
The message centre will display the gap set.
E97091
WARNING
When in follow mode, the vehicle will
not decelerate automatically to a stop,
nor will the vehicle always decelerate
quickly enough to avoid a collision, without
driver intervention.

161
Adaptive cruise control (ACC)

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.
• 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 ACC.
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. 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.
Changing the follow mode set gap
The gap from the vehicle ahead can be
decreased or increased by rolling the
thumbwheel on the stee ring wheel. Four gap
settings are available and the selected gap
setting will be displaye d on the message centre
when either ACC button is pressed. Each gap level is indicated by an
additional
chevron in front of th e vehicle icon in the
message centre (one chevron (gap level 1)
being the shortest, four chevrons (gap level 4)
being the longest). A fter the ignition is
switched on, the default gap (gap level 3) will
be automatically selected ready for ACC
operation.
Note: When the ignition is switched off, the
gap setting will revert to the default setting
(gap level 3) when switched on again.
Note: It is the driver’s responsibility to select a
gap appropriate to the driving conditions.
Overriding the speed and follow mode
The set speed and gap ca n 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
indicator will go out when the ACC is
overridden by the driver using the accelerator
and CRUISE OVERRIDE will be displayed on
the message centre. When the accelerator is
released the ACC functi on will operate again
and vehicle speed will decrease to the set
speed, or a lower spee d if follow mode is
active.
WARNING
Whenever the driver is overriding the
ACC by depressing the accelerator
pedal, the ACC will not automatically
apply the brakes to ma intain separation from
any vehicle ahead.

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.

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.

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.

Resetting the fuel cut-off
1.Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thor oughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualified advice and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
FUEL FILLER FLAP
Note: The fuel filler flap cannot be opened
when the alarm system is armed.
The fuel filler flap is located on the right-hand
side of the vehicle, at the rear.
1. Ensure that the vehicle is fully unlocked.
Push and release the rear of the flap (in the
area indicated in the illustration) to
unlatch.
2. Pull the fuel filler flap open. The label on
the inside of the flap indicates the correct
fuel for the vehicle. 3.
Twist the cap counte r-clockwise to undo.
4. Stow the cap on the lip provided on the top
of the hinge arm, as shown.
When replacing the cap, turn it clockwise until
the ratchet clicks. Failur e to do so could cause
the Engine malfunction warning indicator to
illuminate.
To close the filler flap, pus h the flap closed until
it latches.
WARNING
The fuel cut-off should never be reset
if you can smell fuel, or a leak can be
seen. Doing so can lead to a fire
which may cause persona l injury or death.
WARNINGS
Open the fuel filler cap slowly and
allow the pressure to release before
fully removing the cap to avoid fuel
spillage due to rapid expansion.
Take note of all warnings and
instructions given on the label affixed
to the inside of the fi ller flap. Failure to
do so may result in injury or death.
