passing another vehicle, does not affect the CC
set speed. The vehicle will return to the set speed
when the accelerator pedal is released. Always
observe posted speed limits.
Engine braking instead of applying the
brakes
CC regulates speed by applying the brakes
lightly. To avoid a loss of speed when driving
down hills, use the engine braking function
instead of letting the CC apply the brakes. In this
situation, the driver can temporarily deactivate the
CC braking function.
To do so:
–
Press the accelerator pedal approx. halfway
down and release it.
> CC will automatically deactivate the auto-
matic brake function and will then only

Distance Alert
*
Distance Alert is a function that alerts the driver
if the time interval to the vehicle ahead is too
short.
Distance Alert is active at speeds above approxi-
mately 20 mph (30 km/h) and only reacts to a
vehicle ahead that is driving in the same direc-
tion. No information is provided for vehicles driv-
ing toward you, moving very slowly, or at a stand-
still.
Warning light (generic illustration)
A warning light in the windshield glows steadily if
your vehicle is closer to the one ahead than the
set time interval.
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windshield difficult to
see.
Distance Alert only monitors distance to the
vehicle ahead while Adaptive Cruise Control is
in standby mode or off.
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.

Distance Alert
* limitations
Distance Alert uses the same radar sensor as
Adaptive Cruise Control
* and has several limita-
tions.
WARNING
•
The radar sensor has a limited field of
vision. In some situations it may detect a
vehicle later than expected or not detect
other vehicles at all.
•
The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.
•
The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.
•
Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.
•
Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see.
WARNING
•
Poor weather or winding roads can affect
the radar sensor's capacity to detect vehi-
cles ahead.
•
A vehicle's size (e.g., a motorcycle) can
also affect the radar sensor's capacity to
detect another vehicle. This may result in
the warning light illuminating at a shorter
distance than the one that has been set
or not illuminating at all.
•
High speeds may also result in the warn-
ing light illuminating at a shorter distance
than the one that has been set due to
limitations in the radar sensor's range.
For additional information, see also the article
"Radar sensor limitations."

Adaptive Cruise Control (ACC)
*
ACC is an optional system designed to assist
the driver by maintaining a set speed or a set
time interval to the vehicle ahead.
ACC helps provide more relaxed driving on long
trips on highways or other major roads in a rela-
tively even flow of traffic.
The camera and radar sensor monitor the distance to
the vehicle ahead (generic illustration - certain details
may vary from model to model)
The driver sets that desired speed and time inter-
val to the vehicle ahead. When the camera and
radar sensor detects a slower moving vehicle
ahead, your vehicle's speed is automatically
adapted. When there are no longer slower mov-
ing vehicles ahead, your vehicle will accelerate to
resume the set speed.
ACC is designed to follow a vehicle ahead in the
same lane and maintain a time interval to that
||
DRIVER SUPPORT
282
vehicle set by the driver. If the radar sensor does
not detect a vehicle ahead, ACC will instead
maintain the speed set by the driver.
ACC is designed to smoothly regulate speed.
However, the driver must apply the brakes in sit-
uations that require immediate braking such as
when there are great differences in speed
between vehicles, or if the vehicle ahead brakes
suddenly. Due to limitations in the radar sensor,
braking may occur unexpectedly or not at all.
Adaptive Cruise Control can follow another vehi-
cle from a standstill up to 125 mph (200 km/h).
Always observe posted speed limits.
The driver can also toggle between ACC and
Cruise Control (CC) – see the article "Switching
between Cruise Control and Adaptive Cruise
Control".
WARNING
•
It is advisable to read through all of the
related articles pertaining to ACC (see
the list at the end of this article).
•
Adaptive Cruise Control cannot cover all
driving situations and traffic, weather and
road conditions.
•
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.
Overview
The distance to the vehicle ahead (in the same
lane) is monitored by a radar sensor. Your vehi-
cle's speed is regulated by accelerating and
braking. The brakes may emit a sound when they
are being modulated by the adaptive cruise con-
trol system. This is normal.
WARNING
•
Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible for applying the brakes if the
system does not detect another vehicle.
•
Adaptive Cruise Control does not react to
people or animals, or small vehicles such
as bicycles and motorcycles. It also does
not react to slow moving, parked or
approaching vehicles, or stationary
objects.
•
Do not use Adaptive Cruise Control in
demanding driving conditions such as city
driving or other heavy traffic situations, in
slippery conditions, when there is a great
deal of water or slush on the road, during
heavy rain or snow, in poor visibility, on
winding roads or on highway on- or off-
ramps.

Collision warning
Warning light in the windshield
Adaptive Cruise Control can exert brake force
that is equivalent to approximately 40% of the
vehicle's total braking capacity.
In situations requiring more brake force than
ACC can provide and if the driver does not apply
the brakes, an audible signal from the City Safety
system will sound and warning light will illuminate
in the windshield to alert the driver to react.
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windshield difficult to
see.
||
DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.

WARNING
Adaptive Cruise Control only warns of vehicles
detected by the radar sensor. In some cases
there may be no warning or the warning may
be delayed. The driver should always apply the
brakes when necessary.

vehicle's speed.
A temporary increase in speed, such as when
passing another vehicle, does not affect the ACC
set speed. The vehicle will return to the set speed
when the accelerator pedal is released.
Automatic standby mode
ACC interacts with other systems, such as
Electronic Stability Control. If any of these other
systems are not functioning properly, ACC will
turn off automatically.
WARNING
If this happens, the driver will be alerted by an
audible signal and a message in the instru-
ment panel. The driver will have to adapt the
vehicle's speed, apply the brakes when nec-
essary and keep a safe distance to the vehicle
ahead.

•
the vehicle's speed goes below approx.
3 mph (5 km/h) and ACC cannot determine
if the vehicle ahead is stationary or is an
object such as a speed bump, etc
•
the vehicle's speed goes below approx.
3 mph (5 km/h) and the vehicle ahead
changes lanes or turns so that ACC no
longer has a target vehicle to follow
•
