146* Option/accessory, for more information, see Introduction.
WARNING
•Adaptive Cruise Control is not a colli-
sion 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 sta-
tionary objects.
•Do not use Adaptive Cruise Control in
demanding driving conditions such as
city driving or other heavy traffic situa-
tions, 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 high-
way on- or off-ramps.
Fault tracing and actions
If the message Radar blocked See manual is
displayed, this means that the radar signals
from the sensor have been obstructed and that
a vehicle ahead cannot be detected.
This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning
System with Auto-brake and Pedestrian
Detection will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the
radar.

CauseAction
Swirling water or snow from the surface of the road may interfere with
the radar signals.No action possible. A very wet or snow-covered road surface may affect
the function of the radar.
The surface of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that
it is no longer obstructed.

Press Brake To hold + an
audible signalThe vehicle is at a standstill and ACC will release the brakes before the parking brake engages to keep
the vehicle stopped but a problem with the parking brake means that the vehicle may begin to roll.
The driver will have to apply the brakes. The message will remain in the display and the audible signal
will continue until the driver applies the brakes or presses the accelerator pedal.
–Below 20 mph Only follow-
ingThis is displayed if you try to activate ACC at speeds below approx. 18 mph (30 km/h) without a vehicle
ahead within range (approx. 100 ft/30 meters).

Distance Alert*
04
* Option/accessory, for more information, see Introduction.149 Introduction
Distance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Distance Alert is active at speeds above
approximately 18 mph (30 km/h). Time interval
information is only given for a vehicle that is
driving ahead of your vehicle in the same direc-
tion. No information is provided for vehicles
driving toward you, moving very slowly, or at a
standstill.
Amber warning light1.
An amber warning light in the windshield glows
steadily if your vehicle is closer to the one
ahead than the set time interval.
NOTE
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.
Operation
Press the button in the center instrument panel
to switch this function on or off. The indicator
light in the button illuminates when the function
is on.Depending on the optional equipment
selected, there may not be room for a Distance
Alert button in the center console. In this case,
the function is controlled through the menu
system. Press MY CAR and go to Settings
Car settingsDistance alertOn/Off.

150* Option/accessory, for more information, see Introduction.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval. One bar rep-
resents approximately
1 second to the vehicle ahead; 5 bars is
approximately 2.5 seconds.
The number of bars indicating
the selected time interval are
shown while the setting is
being made and for several
seconds afterward. A smaller
version of the symbol is then
shown to the right in the dis-
play. The same symbol is displayed when
Adaptive Cruise Control (ACC) is activated.
NOTE
•The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
•The set time interval is also used by
Adaptive Cruise Control, see page 140.
WARNING
Only use a time interval that is suitable in
current traffic conditions.
Limitations
Distance Alert uses the same radar sensor
used by Adaptive Cruise Control and the Col-
lision Warning system. See page 144 for more
information on the radar sensor’s limitations.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
WARNING
•Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
•The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.

153 Function
Location of the laser sensor in the windshield2
City Safety™ monitors traffic ahead of you
using a laser sensor mounted in the upper sec-
tion of the windshield. If a collision is imminent,
City Safety™ will automatically apply the
brakes, which may feel like hard braking.
If the difference in speed between your vehicle
and the vehicle ahead is more than approxi-
mately 9 mph (15 km/h), City Safety™ alone
cannot prevent a collision from taking place.
The driver must apply the brakes to help avoid
a collision or reduce its effect.
When the function activates and applies the
brakes, a message will appear in the informa-tion display to indicate that the system is/has
been active.
NOTE
•When City Safety™ applies the brakes,
the brake lights will illuminate.
•In cases where City Safety™ has stop-
ped the vehicle, the system will then
release the brakes. The driver must
apply the brakes to keep the vehicle at
a standstill.
Using City Safety™
NOTE
The City Safety™ function is activated auto-
matically each time the engine has been
switched off and restarted.
On and OffIn certain situations, it may be desirable to
switch City Safety™ off, such as when driving
in close quarters where leaves, branches, etc.
may obscure the hood and windshield.
When the engine is running, City Safety™ can
be switched off as follows:Press My Car in the center console control
panel and go to Settings
Car settings
Driver support systemsCity Safety.
Select
Off.
If the engine is switched off, City Safety™ will
reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
•Follow the same procedure as for switch-
ing City Safety™ off but select On.
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.

WARNING
The laser sensor has certain limitations and
its function may be reduced (or it may not
function at all) in conditions such as heavy
rain or snowfall, or by dense fog or thick,
blowing dust or snow. Condensation, dirt,
ice or snow on the windshield may also
interfere with the sensor’s function.
Objects such as warning flags hanging from
long objects on the roof or accessories such as
auxiliary lights or protective arches on the front
of the vehicle that are higher than the hood may
also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 132) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits a laser beam and measures
the way in which the light is reflected. There-
fore, vehicles or objects with low-reflective sur-
faces may not be detected. Normally, the
license plate and taillight reflectors give the
rear section of a vehicle ahead sufficient reflec-
tive surfaces to be detected.
NOTE
•Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc. See
page 153.
•Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and snow.
•Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead of
you, which means that the system is not func-
tioning.
However, this message will not be displayed in
all situations in which the sensor is obstructed.
For this reason, the driver must ensure that the
area of the windshield in front of the sensor is
always kept clean.
The following table shows some of the situa-
tions that can cause the message to be dis-
played and suggested actions.
CauseAction
The area of the
windshield in front of
the sensor is dirty or
covered by ice or
snow.Clean the wind-
shield or remove the
ice/snow.
The laser sensor's
field of view is
obstructed.Remove the
obstruction.

WARNING
Eye injury may occur if any of the following
points are not followed:
•It is essential that all pertinent instruc-
tions be followed when handling laser
instruments. Testing, repairing, remov-
ing, adjusting and/or replacing any
components in the laser sensor may
only be done by a trained and qualified
Volvo service technician.
•Do not remove the laser sensor (includ-
ing removal of the lenses). A laser sen-
sor that has been removed belongs to
laser class 3B according to standard
IEC 60825-1. Devices in laser class 3B
present a risk of injury to the eyes.
•The laser sensor’s connector must be
disconnected before the sensor is
removed from the windshield.
•The laser sensor must be mounted in
place on the windshield before con-
necting the sensor’s connector.
•Do not view the laser sensor (which
emits spreading, invisible laser beams)
with optical instruments from a distance
of less than 4 inches (100 mm).
Symbols and messages in the display
When City Safety™ automatically applies the
brakes, one or more of the symbols in the main
instrument panel may illuminate and its asso-
ciated message will be displayed.
A text message can be erased by pressing
briefly on the OK button on the turn signal
lever.
