Distance Alert*
04
148* Option/accessory, for more information, see Introduction.
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.

* Option/accessory, for more information, see Introduction.149
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 139.
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 143 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.

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 130) 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 152.
•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.

CAUTION
If a crack, scratch or stone chip should
occur in the section of the windshield in
front the laser sensor, contact a trained and
qualified Volvo service technician to repair
or replace the windshield (see the illustra-
tion showing the location of the sensor on
page 152). Failing to do so may result in
reduced City Safety™ functionality.
To help prevent reduced functionality,
please also observe the following:
•Before the windshield is replaced, con-
tact a Volvo retailer to ensure that the
correct windshield is ordered and
installed. If the wrong type of windshield
is used, this may cause City Safety™ to
function improperly or not at all. Volvo
recommends the use of only Genuine
Volvo Replacement Windshields.
•When replacing windshield wipers, use
the same type or ones approved by
Volvo.

04 Driver support
Collision warning with Full Auto-brake and Pedestrian Detection*
04
158* Option/accessory, for more information, see Introduction.
WARNING
•Collision Warning will not provide a
warning or brake the vehicle for pedes-
trians in darkness or in tunnels, even if
there is street lighting in the area.
•The auto-brake function can help pre-
vent a collision or reduce the speed at
impact but the driver should always
apply the brakes for the best possible
braking effect, even if auto-brake is
actively applying the brakes.
•Never wait for a collision warning. This
system is designed to be a supplemen-
tary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed, even when the colli-
sion warning system is in use.
•Maintenance of the Collision Warning
system's components must only be
performed by a trained and qualified
Volvo technician.
Function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work
together to detect a pedestrian, stationary
vehicles and vehicles that are moving in the
same direction as your vehicle. If there is a risk
of collision with a vehicle or a pedestrian, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increase after
the collision warning has been given, Brake
Support is activated. Brake Support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided. Brake Support also
increases brake force if the system determines
that the driver has not applied adequate pres-
sure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes or begun to steer around the
vehicle or pedestrian, the auto-brake function
is activated without the driver pressing the
brake pedal. Full brake force is applied to help
reduce the vehicle’s speed when the collision
occurs or limited brake force is applied if this
is sufficient to avoid the collision.
NOTE
The auto-brake and brake support functions
are always on and cannot be turned off.

Warning distance.
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal.
WARNING
•The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
•Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
•For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 148.
NOTE
•When Adaptive Cruise Control is used,
the warning light and signal will be used
by that function, even if the warnings
provided by Collision Warning have
been deactivated by the driver.
•In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by pressing MY CAR on the center
console control panel and going to Settings
Car settingsDriver support systems
Collision Warning.
Limitations
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal.
Slippery driving conditions increase braking
distance, which can reduce the system's

capacity to avoid a collision. In these condi-
tions, the ABS and DSTC systems provide the
best possible braking effect while helping to
maintain stability.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.
WARNING
•In certain situations, the system cannot
provide warnings or warnings may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian or a vehicle ahead.
•Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
•The sensor system has a limited range
for pedestrians and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions or in poor visibility.
The Collision Warning system uses the same
radar sensors as Adaptive Cruise Control. For
more information on the radar sensor and its
limitations, see page 143.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 159). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
WARNING
•The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
•The driver's actions always have high-
est priority and override the Collision
Warning system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
•When Auto-brake has prevented a col-
lision with a stationary object, your vehi-
cle will remain at a standstill for approx.
1.5 seconds. If your vehicle has been
braked for a moving vehicle ahead, your
vehicle's speed will be reduced to the
same speed as that vehicle's.
