ENTERING FOLLOW MODE
When in follow mode, the vehicle will
not decelerate automat ically to a stop,
nor will the vehicl e always decelerate
quickly enough to av oid a collision.
Note: Follow mode cannot be disengaged
independently from the speed maintenance
aspect of cruise control.
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 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.
• 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 a nd 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.
The amber warning lamp in the
instrument panel will be
illuminated.

CHANGING THE FOLLOW MODE SET
GAP
Four gap settings are available and the selected
gap setting will be displayed on the message
centre when the gap adjustment control is
operated.
Each gap level is indi cated by an additional
chevron in front of the vehicle icon in the
message centre (one chevron (gap level 1)
being the shortest, four chevrons (gap level 4)
being the longest).
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 res ponsibility to select a
gap appropriate to the driving conditions.
OVERRIDING THE SPEED AND
FOLLOW MODE
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 warning lamp 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 function will
operate again and vehicle speed will decrease
to the set speed, or a lower speed if follow
mode is active.
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 warning
lamp will go out.
If the brakes were bei ng 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.
ACC AUTO OFF
ACC will disengage, but not clear the memory
when:
• The CANCEL button is pressed
• The brake pedal is pressed
• Neutral ( N), Park (P ) or Reverse ( R) gear is
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
RESUME should only be used if the
driver is aware of the set speed and
intends to return to it.
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
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 accele ration 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.
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 is unable to detect any objects ahead,
then 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 ro ads with few objects
for the radar to detect.
Clearing the obstruction fr om in front of the
sensor allows the system to return to normal
operation. If the obstr uction is present when
ACC is inactive (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 for your
vehicle, may have different sizes. This can
affect the correct operation of the ACC.
FORWARD ALERT FUNCTION
Limited detect ion and warning of objects
ahead, is provided duri ng ACC operation by the
ACC Forward Alert warning. The enhanced
forward alert feature additionally provides
warnings when ACC is not engaged; if an object
is detected close ahead, then the warning tone
and message will be issu ed. The brakes will not
be applied.
The forward alert system does not initiate any
action. The driver must take appropriate action
when the Forward Alert message is displayed.
However, the system monitors driver actions
(e.g. braking, steering or indicating) and may
not initiate the warning display if the
appropriate action has been taken early
enough.
Press the button to switch Forward alert on or
off.
When the warning lamp in the
instrument panel is on, Forward
alert is active.

The sensitivity of th e warning can only be
adjusted with ACC disengaged. Adjust as
follows:
• Roll the gap adjustment control
downwards to decrease the sensitivity of
the alert.
• Roll the gap adjustment control upwards to
increase the sensitivity of the alert.
Note: The forward alert set gap is retained
when the ignition is switched off.
Forward Alert is displayed in the message
centre.ADVANCED EMERGENCY BRAKE
ASSIST
The system may not react to slow
moving vehicles and will not react to
stationary vehicles or vehicles
travelling in the opposite direction.
Warnings may not appear if the
distance to the vehicle ahead is very
small or if steering wheel or pedal
movements are large (e.g. to avoid a
collision).
The system utilises the same radar
sensor as ACC and Forward alert - the
same limitations of performance
apply.
Advanced emergency brake assist is available
at speeds above approximately 7 km/h (5 mph)
and improves brakin g response during
emergency braking, when a moving vehicle is
detected close ahead.
If the risk of collision increases after the
Forward Alert warning is displayed, advanced
emergency brake assist is activated. The
brakes are automatically applied gently in
preparation for rapid braking (this may be
noticeable). If the brake pedal is then pressed
quickly, full braking is implemented, even if
only light pressure is ap plied to the pedal. See
87, EMERGENCY BRAKE ASSIST (EBA) .
Note: Braking performance will only be
improved if the driver applies the brakes.
Advanced emergency brake assist will function
even if Forward Alert and ACC are switched off.
If there is a fault with the system, Forward
Alert Unavailable is displayed in the message
centre. The vehicle can st ill be driven and the
braking system will still operate, but without
advanced emergency brake assistance. Seek
qualified assistance to have the fault rectified.

INTELLIGENT EMERGENCY BRAKING
The system may not react to slow
moving vehicles.
The system will not react to stationary
vehicles, or vehicles that are not
travelling in the same direction as
your vehicle.
Warnings and automatic braking may
not occur if the dist ance to the vehicle
ahead is very small, or if the steering
wheel and pedal movements are large
(to avoid a collis ion for example).
IEB (Intelligent Em ergency Braking)
uses the same radar sensor as
Adaptive Cruise Control and Forward
Alert. The same performance
limitations apply, see 96, ADAPTIVE
CRUISE CONTROL OVERVIEW.
IEB is available at all speeds to automatically
apply the brakes if an unavoidable collision
with a moving vehicle in front is detected.
If there is an imminent risk of collision, an
audible warning is given. If the collision then
becomes unavoidable, the IEB system applies
the brakes at up to maximum pressure. After
IEB has activated, IEB System Was Activated
is displayed in the message centre and the
system is inhibited from further operation until
reset by a Dealer/Authorised Repairer.
IEB will function even if Forward Alert and ACC
are switched off. If the radar sensor is blocked,
by snow or heavy rain for example, or there is
a fault with the system, IEB Not Available is
displayed in the message centre. The vehicle
can still be driven and the braking system will
still operate, but without IEB. If the cause of
this message being disp layed is thought to be
other than a blocked rada r sensor, consult your
Dealer/Authorised Repairer.

Automatic speed limiter
103
Automatic speed limiterUSING ASL
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set speed limit. This
is because engine braking is unable to
maintain or reduce the vehicle speed.
The ASL button allows the driver to select
between 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.
SETTING A SPEED LIMIT
• Press the ASL button.
• Use the cruise control speed adjustment
control to set the required speed. The
message centre display in the instrument
panel will show the selected speed.
• The set speed can be adjusted at any time,
using the cruise cont rol speed adjustment
control.
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 suspende d by pressing the
CANCEL button. 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,
however, ASL will only reinstate if the vehicle
speed is less than the current speed set in
memory and greater th an 30 km/h (18 mph).
The message centre will display an appropriate
message if the vehicle speed is too fast to
resume ASL.
ASL WARNING LAMP
Illuminates (amber) when
Automatic Speed Limiter is active.
