Stability system
04
148* Option/accessory, for more information, see Introduction.
Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.
Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Trailer Stability Assist – TSA*Trailer Stability Assist helps stabilize a vehicle
that is towing a trailer when the vehicle and
trailer have begun to sway. See page 281 for
more information.
This system is automatically deactivated if the
driver selects Sport mode.
Operation
Sport modeThe stability system is always activated and
cannot be switched off.
However, the driver can select Sport mode,
which offers more active driving characteris-
tics. In this mode, the engine management sys-
tem monitors movement of the accelerator
pedal and steering wheel for sportier driving byallowing more lateral movement of the rear
wheels before DSTC is activated.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily use Sport mode for maximum
tractive force.
If the driver releases pressure on the acceler-
ator pedal, DSTC will also activate to help sta-
bilize the vehicle.
To switch to Sport mode:
1.
Press the My Car button in the center con-
sole control panel and select My XC70
DSTC in the menu.
2. Unselect the symbol and leave the menu
by pressing EXIT.
>
This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is
switched off. DSTC will return to normal mode
when the engine is restarted.

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.155
WARNING
Adaptive Cruise Control only warns of vehi-
cles detected by the radar sensor, see
page 158. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level
roads. The system may have difficulty main-
taining the correct distance to a vehicle ahead
on steep inclines, if the vehicle is carrying a
heavy load or is towing a trailer. In these situa-
tions, the driver should always be prepared to
apply the brakes if necessary.

Distance Alert*
04

* Option/accessory, for more information, see Introduction.163 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

Collision warning with Full Auto-brake and Pedestrian Detection*
04

* Option/accessory, for more information, see Introduction.171 Introduction
Collision Warning with Full Auto-brake and
Pedestrian Detection is designed to assist the
driver if there is a risk of a collision with a
pedestrian, a vehicle ahead that is at a stand-
still or one that is moving in the same direction
as your vehicle.
Collision Warning consists of the following
three functions:
•Collision Warning warns the driver of a
potential collision situation.
•Brake Support helps the driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision with a pedestrian or
another vehicle cannot be avoided and the
driver does not apply the brakes in time or
steer around the person/vehicle. Auto-
brake can help prevent a collision or
reduce the speed at which a collision
occurs.
Since Collision Warning with Full Auto-brake
and Pedestrian Detection is activated in cir-
cumstances where the driver should have
begun braking much sooner, the system will
not be able to assist the driver in all situations.
This system is designed to activate as late as
possible to help avoid unnecessary interven-
tion.The system should not be used in such a way
that the driver changes his/her way of operat-
ing the vehicle. If the driver relies entirely on the
system, the chances of an accident eventually
occurring increase considerably.
The Collision Warning and City Safety™ sys-
tems supplement each other. See page 166 for
detailed information about City Safety™.
WARNING
No automatic system can be guaranteed to
function 100% correctly in all situations. For
that reason, never test the Auto-brake sys-
tem by driving toward a person or object.
This could result in serious injury or death.
WARNING
•Collision Warning does not work in all
driving, traffic, weather and road condi-
tions. It does not react to vehicles not
traveling in the same direction as your
vehicle.
•Collision Warning does not react to ani-
mals.
•Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using Collision Warning.
•Collision Warning will not provide a
warning or brake the vehicle for pedes-
trians at speeds above 50 mph
(80 km/h).

Park assist*
04
186* Option/accessory, for more information, see Introduction.
Signals from the park assist system
View in the display (warning for objects front left/
right rear)
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The marked sectors in the display indicate that
one or more of the sensors has detected an
object. The closer the car symbol comes to a
sector, the closer the vehicle is to the object.
If the infotainment system is switched off, the
park assist system will not be able to provide a
visual indicator. An audible signal will still be
provided.
Audible signalThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle. If there are
objects within this distance both behind and in
front of the vehicle, the tone alternates
between front and rear speakers.
NOTE
The level of the audible signal can be low-
ered/raised with the infotainment volume
control. The level can also be set in the MY
CAR menu system, see page 132.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
G017833
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.

04 Comfort and driving pleasure
Rear Park Assist Camera (PAC)*
04
190* Option/accessory, for more information, see Introduction.
Using PAC
Activation
PAC is activated when the gear selector is
moved to R if the system is selected in the MY
CAR menu system or by pressing the CAM
button in the center console. See page 131 for
a description of the menu system.
If the Volvo Navigation System (VNS) is in use,
PAC will automatically override the navigation
system to show the camera's image on the
screen instead of navigation information, for as
long as reverse gear is selected.
ZoomThe camera can be useful when attaching a
trailer. Press CAM to zoom in on the trailer
hitch (and press this button again to return to
the normal camera view).With the camera zoomed in on the trailer hitch,
a guiding line showing the hitch's path toward
the trailer will be projected. This feature can be
activated in the MY CAR menu, see
page 132. The guiding lines for the wheels (see
the following section "Guiding lines") and for
the trailer hitch cannot be displayed at the
same time.
If the camera shows an enlarged (zoomed)
image, turn TUNE counterclockwise, or press
EXIT, CAM or OK to return to a normal view.
DeactivationMove the gear selector from R to another posi-
tion. There is a slight delay in the PAC system,
which means that the view from behind the
vehicle will remain on the screen for approxi-
mately 15 seconds after the gear selector has
been moved from the R position or until the
vehicle reaches a forward speed of 6 mph
(10 km/h). The screen will then revert to the
mode that it was in before R was selected and
will, for example, display navigation system
information.
NOTE
If any button on the center console control
panel is pressed, the camera image will dis-
appear from the display. Pressing CAM will
return the camera image to the display.
Guiding lines
The lines on the screen are projected as if they
were a path on the ground behind the vehicle
and are affected by the way in which the steer-
ing wheel is turned. This enables the driver to
see path the vehicle will take, even if he/she
turns the steering wheel while backing up.
NOTE
When backing up with a trailer, the guiding
lines show the path that the vehicle will
take, not the trailer.

Blind Spot Information System*
04
194* Option/accessory, for more information, see Introduction.
When does BLIS function
The system functions when your vehicle is
moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another vehicle:The system reacts if your vehicle is passed by
another vehicle at a speed of up to 43 mph
(70 km/h) faster than your vehicle.
WARNING
•BLIS does not function in sharp curves.
•BLIS does not function when your vehi-
cle is backing up.
•If you are towing a wide trailer, this may
prevent the BLIS cameras from detect-
ing other vehicles in adjacent lanes.
How BLIS functions in daylight and
darkness
Daylight
BLIS reacts to the shape of surrounding vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
DarknessBLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, a
vehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or truck.
WARNING
•BLIS does not react to cyclists or
mopeds.
•BLIS does not react to vehicles that are
standing still.
•The BLIS cameras have the same limi-
tation as the human eye. In other words,
their "vision is impaired" by adverse
weather conditions such as heavy
snowfall, intense light directly into the
camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s)
may illuminate even when there are no other
vehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa-
sionally even when there are no other vehi-
cles in the blind area, this does not indicate
a fault in the system.
In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa-
tions in which the BLIS indicator light(s) may
illuminate even when there are no other vehi-
cles in the area monitored by the system.
