Adaptive Cruise Control; Automatic Gearbox - Volvo V40 Owner's Manual

General information on ACC
The adaptive cruise control (ACC – Adaptive
Cruise Control) helps the driver maintain a safe
distance from the vehicle ahead. Adaptive
cruise control provides a more relaxing driving
experience on long journeys on motorways
and long straight main roads in smooth traffic
flows.
The driver sets the desired speed and time
interval to the car in front. When the radar
detector detects a slower vehicle in front of the
car, the speed is automatically adapted to that.
When the road is clear again the car returns to
the selected speed.
If the adaptive cruise control is switched off or
set to the standby mode and the car comes too
close to a vehicle in front, then the driver is
warned instead by Distance Warning (see
page 158) about the short distance.
1 NOTE: The illustration is schematic - details may differ depending on car model.
WARNING
The driver must always be observant with
regard to the traffic conditions and intervene
when the adaptive cruise control is not
maintaining a suitable speed or suitable dis-
tance.
The adaptive cruise control cannot handle
all traffic, weather and road conditions.
Read the whole of this section for informa-
tion on the limitations of the adaptive cruise
control. The driver must be familiar with this
information before using the adaptive cruise
control.
The driver always bears responsibility for
maintaining the correct distance and speed,
even when the adaptive cruise control is
being used.
IMPORTANT
Maintenance of adaptive cruise control
components must only be performed at a
workshop - an authorised Volvo workshop
is recommended.
