Managing The Speed Of The Adaptive Cruise Control - Volvo XC 90 Owner's Manual

Start Adaptive Cruise Control
In order to start the ACC the following require-
ments apply:
•
The driver's seatbelt must be buckled and
the driver's door must be closed.
•
There must be a vehicle (the "target vehicle")
in front of the car, or the current speed must
be at least 15 km/h.
–
With the symbol/function
press the steering wheel button
> Adaptive Cruise Control starts, and the
current speed is stored as the desired
speed in memory and is shown in figures
in the centre of the speedometer.
The time interval is only
adjusted to the vehicle ahead
by the ACC when the distance
symbol shows two vehicles.
At the same time a speed
range is marked.
The higher speed is the
stored/set speed and the lower
speed is that of the preceding
vehicle (target vehicle).

– Change the stored speed with short or long
presses on steering wheel button
- (3):
•
To change in steps of +/– 5 km/h, use
short presses — each press results in a
change of +/– 5 km/h.
•
To change in steps of +/– 1 km/h, hold
the button depressed and release it when
the indicator (4) in the driver display
shows the desired speed.
> The speed set after the last press is
stored in the memory.
If the driver increases the car's speed using the
accelerator pedal before pressing the steering
wheel button , the speed stored will be the
car's speed when the button is depressed, provi-
ded the driver's foot is on the accelerator pedal at
the moment when the button is depressed.
A temporary increase in speed with the accelera-
tor pedal, e.g. during overtaking, does not affect
the setting - the car returns to the last stored
speed when the accelerator pedal is released.
Note that the lowest programmable speed for
Adaptive Cruise Control is 30 km/h - even
though it is capable of following another vehicle
down to a standstill, a speed lower than 30 km/h
cannot be selected/stored.
After-sales fitted ACC
Cars originally supplied with a standard Cruise
control can be fitted afterwards with the Adaptive
(1) or
cruise control function. An after-sales fitted ACC
differs from the factory mounted version with
respect to the following points:
•
When the speed of the preceding vehicle is
less than 30 km/h the ACC switches to the
standby mode - the driver must then inter-
vene and manually maintain a suitable dis-
tance to the vehicle in front.
•
The lowest speed at which ACC can be acti-
vated is 30 km/h.
