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 center 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 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 center. 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
Four gap settings are available. Each gap level
is indicated by an additional chevron in front of
the vehicle icon in the message center (one
chevron (gap level 1) being the shortest, four
chevrons (gap level 4) being the longest). After
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
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 amber warning lamp in the
instrument panel will be
illuminated.
