2013 VOLVO XC70 warning

04 Driver support
Adaptive Cruise Control (ACC)*
04
* Option/accessory, for more information, see Introduction.143
Please note that the lowest speed that can be
set is 18 mph (30 km/h), although ACC can
maintain a set speed/distance to a vehicle
ahead down to a standstill. Queue Assist con-
sists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the
driver's seat belt must be fastened before
ACC can be put in active mode. If the driv-
er's seat belt is taken off or if the driver's
door is opened, ACC will return to standby
mode.
Your vehicle can maintain the set time interval
to the vehicle ahead at any permissible speed,
including a complete stop.
In order to activate ACC at speeds below
18 mph (30 km/h):
•The vehicle ahead must be within a rea-
sonable distance (not farther away than
approx. 100 ft/30 meters)
•The lowest speed that can be selected is
18 mph (30 km/h), although ACC will also
help maintain the set time interval to the
vehicle ahead at lower speeds, including a
complete stop.During short stops (less than approximately
3 seconds) in slow-moving traffic, your vehicle
will begin moving again automatically as soon
as the vehicle ahead begins to move.
If it takes more than 3 seconds for the vehicle
ahead to begin moving, ACC will be automati-
cally go into standby mode.
The driver will then have to reactivate ACC in
one of the following ways:
•By pressing
•By accelerating up to at least 3 mph
(4 km/h). ACC will then resume following
the vehicle ahead.
Your vehicle will then resume following the
vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehi-
cle at a standstill for up to 4 minutes. After
4 minutes have elapsed, the parking brake
will be engaged and ACC will go into
standby mode.
To reactivate ACC, the driver must release
the parking brake (see page 125).
Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be
a stationary vehicle ahead
The following only applies at speeds below
approximately 18 mph (30 km/h):
If ACC changes target vehicles (the vehicle that
the radar sensor has detected) from a moving
vehicle to a stationary one, the system will
apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and
apply the brakes but will instead accelerate
to the previously set speed. The driver must
actively apply the brakes to stop the vehicle.
ACC disengages and goes into standby mode
if:

144* Option/accessory, for more information, see Introduction.
•Your vehicle's speed goes below 10 mph
(15 km/h) and ACC cannot determine if the
target object is a stationary vehicle or some
other type of object such as e.g., a speed
bump.
•Your vehicle's speed goes below 10 mph
(15 km/h) and the vehicle ahead turns so
that ACC no longer has a target vehicle to
follow.
No automatic braking when at a
standstill
In certain situations, ACC will no longer apply
the brakes and go into standby mode while the
vehicle is not moving. This means that the
driver will have to apply the brakes.
This happens if:
•The driver presses the brake pedal
•The parking brake is activated
•The gear selected is moved to P,N or R
•The driver presses the button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the parking
brake in order to continue keeping the vehicle
at a standstill.
This happens if:
•The driver opens the door or takes off
his/her seat belt
•DSTC is put in Sport mode (see page 132)
•ACC has kept the vehicle at a standstill for
more than 2 minutes
•The engine has been switched off
•The brakes have overheated
Turning ACC off completely
•From standby mode, press once.
•From active mode, press twice.
The set speed and time interval are then
cleared from the system's memory and cannot
be resumed by pressing
.
The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 149) and Collision Warning with Full
Auto-brake and Pedestrian Detection (see
page 158). This sensor is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle, in the same lane.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor's capacity to detect vehicles
ahead is impeded:
•if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean.
•if the speed of vehicles ahead is signifi-
cantly different from your own speed.

Situations where ACC may not function
optimally
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.
•If ACC is not functioning properly,
cruise control will also be disabled.
Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters the
lane between your vehicle and the target
vehicle.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
In curves, the radar sensor may detect the
wrong vehicle or lose sight of the target
vehicle.
WARNING
•Adaptive Cruise Control cannot cover
all driving situations and traffic, weather
and road conditions. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using this feature.
•This system is designed to be a supple-
mentary 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 and must intervene if
Adaptive Cruise Control does not main-
tain a suitable speed or suitable dis-
tance to the vehicle ahead.
•Maintenance of ACC components may
only be performed by a trained and
qualified Volvo technician.

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.

04 Driver support
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.

City Safety™
04
152
Introduction
City Safety™1 is a support system designed to
help the driver avoid low speed collisions when
driving in slow-moving, stop-and-go traffic.
City Safety™ is not active if your vehicle’s
speed is below approximately 2 mph (4 km/h).
This means that City Safety™ will not react if
your vehicle approaches another vehicle at
very low speed, for example, when parking.
The function is active at speeds up to approx-
imately 30 mph (50 km/h) and assists the driver
by applying the brakes automatically, thereby
avoiding or helping to reduce the effects of a
collision.
City Safety™ is designed to intervene as late
as possible to help avoid unnecessary activa-
tion.
City Safety™ triggers brief, forceful braking if a
low-speed collision is imminent. However, the
system will not intervene in situations where
the driver actively steers the vehicle or applies
the brakes, even if a collision cannot be avoi-
ded. This is done in order to always give the
driver’s actions highest priority.
City Safety™ activates in situations where the
driver has not applied the brakes in time, whichmeans that the system cannot help the driver
in all situations.
City Safety™ should not be used to alter the
way in which the driver operates the vehicle.
The driver should never rely solely on this sys-
tem to safely stop the vehicle.
Normally, the occupants of the vehicle will not
be aware of City Safety™ except when the
system intervenes when a low-speed collision
is imminent.
If the vehicle is also equipped with the optional
Collision Warning with Full Auto-brake and
Pedestrian Detection system, the two systems
interact. For more information about the Colli-
sion Warning with Auto-brake system, see
page 158.
WARNING
•City Safety™ is a supplemental aid to
the driver. It can never replace the
driver’s attention to traffic conditions or
his/her responsibility for operating the
vehicle in a safe manner.
•City Safety™ does not function in all
driving situations or in all traffic, weather
or road conditions.
WARNING
•City Safety™ only reacts to vehicles
traveling in the same direction as your
vehicle and does not react to small vehi-
cles, bicycles or motorcycles or to peo-
ple or animals.
•City Safety™ is not activated when your
vehicle is backing up.
•City Safety™ functions at speeds up to
30 mph (50 km/h). This system can help
prevent a collision if the difference in
speed between your vehicle and the
vehicle ahead is less than 9 mph
(15 km/h). If the difference in speed is
greater, a collision cannot be avoided
but the speed at which the collision
occurs can be reduced. The driver must
apply the vehicle’s brakes for full brak-
ing effect.
•City Safety™ will not intervene in a
potential collision situation if the vehicle
is being driven actively. The driver is
always responsible for maintaining a
safe distance to a vehicle or object
ahead.
