Resuming Speed
If a speed setting is stored in system
memory, press the multifunction
control (RES +) up and take foot off
the accelerator pedal. The last set
speed will be displayed.
WARNING!
The resume function should be used
only when road and traffic conditions
allow it. Resuming too a high or too a
low speed for current traffic and road
conditions could cause a harsh vehicle
acceleration or deceleration which
could jeopardise driving safety and
risk to cause severe accidents.
Setting the Time Gap
The specified time gap has four
different settings, identified by 4
horizontal bars that represent 4
different time gaps:
• Maximum (longest) time: 4 bars.
• Long time: 3 bars (default time).
• Medium time: 2 bars.
• Short time: 1 bar.
Based on both time gap, selected by
the driver, and the actual vehicle
speed, ACC calculates the distance to
keep from the vehicle ahead.
If another information covering ADAS
visualization in the main area (textual
pop ups, NAVI information, phone call,
etc...) are displayed, the ACC time gap
symbol shall be displayed in the top
left corner for the time the ADAS in
the main area is covered (see detail in
picture).
If system does not detect the presence
of any vehicles ahead, only the bars
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
bars, corresponding to the time gap
from vehicle ahead, press and release
the related setting button.
Each press and release of the button
changes the time gap starting from
3 bars (default time) and moving in a
sequential way towards the minimum
time: 3
→
2
→
1
→
4
→
3
→
2
→
1
→
4 and so on.
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.
