Automatic standby mode with change
of target
The adaptive cruise control is disengaged
and set in standby mode:
•
when the speed is below 5 km/h and
cruise control is not sure whether the tar-
get object is a stationary vehicle or some
other object, e.g. a speed bump.
•
when the speed is below 5 km/h and the
vehicle in front turns off so the cruise
control no longer has a vehicle to follow.
Termination of automatic braking at a
standstill
In certain situations, Queue Assist stops
automatic braking at a standstill. This means
that the brakes are released and the car may
start to roll - the driver must therefore inter-
vene and brake the car himself/herself in
order to maintain its position.
Queue Assist releases the foot brake and sets
the adaptive cruise control in standby mode
in the following situations:
•
the driver puts his/her foot on the brake
pedal
•
the parking brake is applied
•
the gear selector is moved to P, N or R
position
•
the driver sets the cruise control in
standby mode.
Automatic activation parking brake
In certain situations Queue Assist applies the
parking brake in order to keep the car remain-
ing stationary.
This takes place if:
•
the driver opens the door or takes off
his/her seatbelt
•
DSTC is changed from Normal to Sport
mode
•
Queue Assist has held the car stationary
for more than 4 minutes
•
the engine is switched off
•
the brakes have overheated.
The radar sensor and its limitations
The radar sensor is used - apart from by
Adaptive cruise control - by the following
functions as well:
•
Collision Warning with Auto Brake, see
page 177
•
Distance Warning, see page 168.
The function of the radar sensor is to detect
cars or larger vehicles in the same direction,
in the same lane.

Adaptive cruise control*
IMPORTANT
In the event of visible damage to the car's
grille, or if you suspect that the radar sen-
sor may be damaged:
•
Contact a workshop - an authorised
Volvo workshop is recommended.
The function may completely or partially
disappear - or malfunction - if the grille,
the radar sensor or its bracket is damaged
or has loosened.
WARNING
The driver must always be observant with
regard to the traffic conditions and inter-
vene when the adaptive cruise control is
not maintaining a suitable speed or suita-
ble distance.
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 con-
trol is being used.
