Warning!
The Resume function should only be used
if traffic and road conditions permit.
Resuming a set speed that is too high or
too low for prevailing traffic and road
conditions could cause the vehicle to
accelerate or decelerate too sharply for
safe operation. Failure to follow these
warnings can result in a collision and death
or serious personal injury.
Setting The Distance
Between Vehicles
The distance between your vehicle and
the vehicle ahead may be set to one
bar (short), two bars (medium), three
bars (long), or four bars (maximum).
Distance Icons
The distances from the vehicle ahead
are proportional to speed.
The interval of time with relation to the
vehicle ahead remains constant and
varies from one second (for the short
distance one-bar setting) to two
seconds (for the maximum distance
four-bar setting).
The set distance is shown on the
display by a dedicated icon.
The setting is four (maximum) the first
time the system is used. After the
distance has been modified by the
driver, the new distance will be stored
also after the system is deactivated and
reactivated.
To Decrease The Distance
Push and release the distance button to
decrease the distance setting. The
distance setting decreases by one bar
(shorter) every time the button is
pushed.

Distance Button
The set speed is held if there are no
vehicles ahead. Once the shortest
distance has been selected, the next
push of the button will set the
maximum distance.
If a slower vehicle is detected in the
same lane, the vehicle icon on the
display illuminates from grey to white.
The system automatically adjusts the
vehicle's speed to keep the set
distance, independently of the set
speed.
The vehicle holds the set distance until:
The vehicle ahead accelerates to a
speed higher than the set speed.
The vehicle ahead leaves the lane or
the detection field of the Adaptive
Cruise Control system sensor.
The distance setting is changed.
The Adaptive Cruise Control system
is deactivated/paused.
Warning!
The maximum breaking applied by the
system is limited. The driver may apply the
brakes in all cases if needed.
If the system predicts that the braking
level is insufficient to hold the set distance,
either "BRAKE!" or a dedicated message is
displayed to warn the driver of approaching
the vehicle ahead. An acoustic signal is
also emitted. In this case, it is advised to
07146S0015EM
brake immediately as necessary to hold a
safe distance from the vehicle ahead.
