User's Manual

When a vehicle ahead enters the same lane or
a slower vehicle is ahead in the same lane, the
vehicle's 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 lamp in the Instrument panel will be
illuminated, see 46, FOLLOW MODE (AMBER).
The Message centre will display the gap, set in
the form of a vehicle with a varying number of
bars in front of it.
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's brakes will be
automatically applied, slowing the vehicle and
maintaining 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 in 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.
If a direction indicator is used, ACC will reduce
the gap to the vehicle ahead so as to respond
more quickly to the anticipated manoeuvre. If
a manoeuvre is not actioned, the previous gap
will be restored after a few seconds. Enhanced
response may not occur if ACC detects that it
is inappropriate, i.e., you are already too close
to the vehicle ahead or you are already in
another lane.
CHANGING THE FOLLOW MODE SET
GAP
It is the driver's responsibility to select
a gap appropriate to the driving
conditions.
Four gap settings are available and the selected
gap setting will be displayed in the Message
centre when either gap adjustment button is
pressed.
Each gap level is indicated by an additional bar
in front of the vehicle icon in the Message centre
(one bar (gap level 1) being the shortest, four
bars (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.
If Winter mode is selected, then the longest gap
(gap level 4) will initially be selected.
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.
