Adaptive Cruise Control –
introduction
ACC is an optional system designed to assist
the driver by maintaining a set speed or a set
time interval to the vehicle ahead. It is primarily
intended for use on long straight roads in steady
traffic, such as on highways and other main
roads.
When the driver has set the desired speed and
the time interval to the vehicle ahead, ACC func-
tions as follows:
•
If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the
set speed.
•
If ACC's radar sensor detects a slower mov-
ing vehicle in the lane ahead, the system will
adapt your vehicle's speed to help maintain
the set time interval to the vehicle ahead.
When there are no longer slower moving
vehicles ahead, your vehicle will accelerate to
resume the set speed.
If ACC is switched off completely or in standby
mode and your vehicle comes too close to
another vehicle ahead, the driver will be warned
by the Distance Alert system (see Distance Alert
– introduction (p. 191)).
WARNING
•
Adaptive Cruise Control cannot cover all
driving situations and traffic, weather and
road conditions. The "Function" section
provides information about limitations that
the driver must be aware of before using
this feature.
•
This system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's attention
and judgement. The driver is responsible
for maintaining a safe distance and speed
and must intervene if Adaptive Cruise
Control does not maintain a suitable
speed or suitable distance to the vehicle
ahead.
•
Maintenance of ACC components may
only be performed by a trained and quali-
fied Volvo technician.
