Driving and Driver Assistance Systems
referred to set time gap will be
displayed.
When system detects the presence of a
vehicle ahead, it is displayed in front of
the bars (see example in the figure).
To increase or decrease the number of
5
bars, corresponding to the time gap from
vehicle ahead, press and release the
related setting "pulse activation" button.
Each press and release of the button
changes the time gap starting from
4 bars (default time) and moving in a
240
sequential way towards the minimum
time: 4→3→2→1→4→3→2→1 and so on.
NOTE:
The set time gap will be maintained in
the next ACC activation.
If there is no vehicle ahead, the vehicle
will maintain the set speed. If a slower
moving vehicle is detected in the same
lane, the system displays the target
vehicle icon before the bars.
From that moment, the system adjusts
vehicle speed automatically to maintain
the time gap setting, regardless of the
set speed.
The vehicle will then maintain the set
time gap until:
• The vehicle ahead accelerates to a
speed above the set speed.
• The vehicle ahead moves out of your
lane or view of the sensor.
• The time gap setting is changed.
• The driver disables the system.
The maximum braking applied by ACC is
limited; however, the driver can always
apply the brakes manually, if necessary.
Any time the ACC system automatically
operates the brakes, the stop lights will
turn on as if the driver was braking.
A Proximity Warning on display will
alert the driver if ACC predicts that its
maximum braking level is not sufficient
to maintain the set time gap.
If this occurs, a visual alert will flash on
the display and a chime will sound while
ACC continues to apply its maximum
braking capacity.
NOTE:
The displayed warning is a warning
for the driver to take action and does
not necessarily mean that the Forward
Collision Warning system is applying the
brakes autonomously.
Overtake Aid
When driving with ACC engaged and
following a target vehicle, the system
will provide an additional acceleration to
assist in passing vehicles in front.
This additional acceleration is triggered
when the driver utilises the left turn
signal to start overtaking. In locations
with left hand drive traffic, overtake aid
is active only when passing on the left
side of the target vehicle.
