Adaptive cruise control
100
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 center. 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 18
mph (30 km/h) the ACC system will be
automatically switched off and the warning
lamp 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 in the message center. The driver
must take control.
ACC AUTO OFF
ACC will disengage, but not clear the memory
when:
The CAN button 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
RESshould only be used if the driver is aware
of the set speed and intends to return to it.
By pressing the RES button after ACC has been
cancelled, after braking for example, 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).
HINTS ON DRIVING WITH ACC
The system acts by regulating the speed of the
vehicle using engine control and the brakes.
Gear changes may occur in response to
deceleration or acceleration while 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 while the system is
active
That using maximum ACC braking only is
not sufficient.
Note: ACC operates when the gear selector 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.
