Changing the set speed
There are three ways to change the set
speed:
1. Accelerate or brake to the required speed and press the ‘SET +’ button.
2. Increase or decrease the speed by pressing and holding either the
‘SET +’ or ‘–’ button until the required
set speed is shown on the message
centre. The vehicle speed will
gradually change to the selected
speed.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing the ‘SET +’ or ‘–’ button.
ACC operates between approximately
20 mph and 110 mph (34 km/h and
180 km/h) dependent on the country
specification.
Set speeds outside this 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 for four seconds after
it has been changed. Changing the gap
The gap from the vehicle ahead can be
decreased or increased by pressing the
gap setting rocker switch on the steering
wheel. Four gaps are available and the
selected gap setting will be displayed on
the message centre when the rocker
switch is pressed. After the ignition is
switched ON the default gap will be
automatically selected ready for ACC
operation.
Note:
It is the driver’s responsibility to
select a gap appropriate to the driving
conditions, and in accordance with
national driving regulations.
ACC automatic switch off
Adaptive cruise control will disengage,
but not clear the memory when:
• The CANCEL button is pressed.
• The brake pedal is pressed.
• The vehicle speed falls below 18 mph (30 km/h).
• Neutral, Park or Reverse gear positions are selected.
• The parkbrake is applied.
• DSC is activated. Adaptive cruise control will disengage,
and clear the memory when:
• The ignition switch is set to
position ‘0’.
• Maximum vehicle speed is reached.
• A fault occurs in the ACC system.
Resuming the set speed/follow mode
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 set
speed will be displayed for four seconds
and the original set speed will be
resumed, unless a vehicle ahead causes
the follow mode to become active.
Caution: ‘RESUME’ should only be
used if the driver is aware of the set
speed and intends to return to it.

Notes on using adaptive cruise
control
1. Adaptive cruise control operates when the gear selector lever is in
position ‘2’, ‘3’ ‘4’ ‘5’ or ‘D’.
2. When engaged, the accelerator pedal rests in the raised position.
Fully release the pedal to allow
normal ACC operation.
3. When braking is applied by the ACC
the brake pedal will move down and
up as braking is applied or removed.
The vehicle brake lights will be
switched on while braking is applied.
!WARNING:
The driver must not rest a foot under
the brake pedal, as it may become
trapped. Driving with ACC active
The system acts by regulating the speed
of the vehicle using engine control and
the brakes. Gear changes may occur in
response to decelerati
on 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 a re d warning light and
the message ‘DRIVER INTERVENE’ if the
ACC detects:
• That using maximum ACC braking only is not sufficient.
• That the vehicle speed has decreased below the minimum for ACC
operation.
• A failure has occurred whilst the system is active.
