Brakes
03

119
•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing through an
automatic car wash can cause water to collect
on the brake discs and pads. This will cause a
delay in braking effect when the pedal is
depressed. To avoid such a delay when thebrakes are needed, depress the pedal occa-
sionally when driving through rain, slush, etc.
This will remove the water from the brakes.
Check that brake application feels normal. This
should also be done after washing or starting
in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less efficient than when driving on
level roads. To reduce the strain on the brakes,
shift into a lower gear and let the engine help
with the braking. Do not forget that if you are
towing a trailer, the brakes will be subjected to
a greater than normal load.
Anti-lock braking system (ABS)The Anti-lock Braking System (ABS) helps to
improve vehicle control (stopping and steering)
during severe braking conditions by limiting
brake lockup. When the system "senses"
impending lockup, braking pressure is auto-
matically modulated in order to help prevent
lockup that could lead to a skid.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehicle
first reaches a speed of approximately 6 mph(10 km/h). The brake pedal will pulsate several
times and a sound may be audible from the
ABS control module, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after
the vehicle has been washed. Do this by brak-
ing gently for a short period while the vehicle is
moving.
Emergency Brake AssistanceEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.

Heavy load uphillA heavy load, such as a trailer, can cause the
vehicle to roll backward when the parking
brake is released automatically on a steep
incline. To help avoid this:
1. Keep the electric parking brake lever
pushed in with the left hand while shifting
into Drive with the right.
2. While pressing the throttle pedal to pull
away, release the parking brake lever only
after the vehicle begins to move.

Climate system
04

* Option/accessory, for more information, see Introduction.137 Introduction
Air conditioningThe vehicle is equipped with Electronic Climate
Control (ECC). The climate control system
cools, heats or dehumidifies the air in the pas-
senger compartment.
NOTE
•The air conditioning can be switched
off, but to ensure the best possible cli-
mate comfort in the passenger com-
partment and to prevent the windows
from misting, it should always be on.
•In warm weather, a small amount of
water may accumulate under the car
when it has been parked. This water is
condensation from the A/C system and
is normal.
Sensor location
•The sunlight sensor is located on the top
side of the dashboard.
NOTE
The sunlight sensor monitors which side of
the car that is most exposed to sunlight.
This can mean that the temperature may
differ between the right and left-side air
vents, even if the temperatures set for both
sides of the passenger compartment are the
same.
•The temperature sensor for the passenger
compartment is located below the climate
control panel.
•The outside (ambient) temperature sensor
is located on the door mirror.
•The humidity sensor* is located in the inte-
rior rearview mirror.
NOTE
Do not cover or block the sensors with
clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works opti-
mally, the side windows, and the optional
moonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-mercially available window washing spray will
also help prevent fogging or misting.
Temporary shut-off of the air
conditioning
The air conditioning is momentarily disen-
gaged during full-throttle acceleration or when
driving uphill with a trailer. This may result in a
temporary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.
Climate system maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
RefrigerantVolvo cares about the environment. The air
conditioning system in your car contains a
CFC-free refrigerant – R134a. This substance
will not deplete the ozone layer. The air condi-
tioning system contains 1.8 lbs (820 g) of
R134a. The systems uses PAG oil.
Passenger compartment filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to

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.

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.
Setting a speedOnce ACC has been put in standby mode, use
the
or buttons to store (set) the vehicle's
current speed. This puts the system in active
mode. The set speed, for example 55 mph, is
shown in the display.

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.

Rear Park Assist Camera (PAC)*
04

* Option/accessory, for more information, see Introduction.189 Introduction
The Park Assist Camera uses the display in the
center console to show the area behind the car
while you are backing up.
PAC also shows guiding lines in the on-screen
image to indicate the direction that the vehicle
will take as it moves rearward, which helps
simplify parallel parking, backing into a tight
space or when attaching a trailer to the vehicle.
WARNING
•PAC is designed to be a supplementary
aid when parking the vehicle. It is not,
however, intended to replace the
driver’s attention and judgment.
•The camera has blind spots where it
cannot detect objects or people behind
the vehicle.
•Pay particular attention to people or ani-
mals that are close to the vehicle.
Function
The driver sees what is behind the vehicle and
if a person or animal should suddenly appear
from the side.
PAC is mounted on the tailgate, near the open-
ing handle.
The camera has built-in electronics that help
reduce the “fish-eye” effect so that the image
shown on the screen is as natural as possible.
This may cause some objects on the screen to
“lean,” which is normal.
WARNING
Objects seen on the screen may be closer
than they appear to be.
Ambient lighting conditionsThe camera automatically monitors the ambi-
ent lighting conditions behind the vehicle and
constantly adjusts sensitivity to light. This may
cause the brightness and quality of the image
on the screen to vary slightly. Sensitivity to light
is increased in dark conditions or in bad
weather, which may affect image quality.
If the image on the screen seems too dark,
brightness can be increased with the thumb
wheel on the lighting panel.
NOTE
In order to function properly, the camera
lens should always be kept clean. This is
particularly important in bad weather. Keep
the lens free of dirt, ice or snow.

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.

image is shown on the center console dis-
play.
•When backing up, two solid lines are pro-
jected on the screen to show the path that
the vehicle's rear wheels will take. These
lines are affected by movements of the
steering wheel. The vehicle's approximate
outer dimension are shown by two dashed
lines.
•The graphic lines will not be displayed
when backing up with a trailer that is con-
nected to the vehicle's electrical system.
•Objects on the ground that are closer than
1 ft (30 centimeters) cannot be detected by
the camera.
•The camera is active for approx.
5 seconds after the gear selector is moved
to R or until the vehicle's speed exceeds
6 mph (10 km/h).
•The optional Park Assist sensors and the
parking camera work together and infor-
mation from the sensors is shown graphi-
cally on the display.
•The graphic lines shown on the screen
when the vehicle backs up can be disabled
in the settings menu.
•Manual zoom can be selected in the MY
CAR menu.
•The system can be switched off by press-
ing CAM. By default, the system is acti-
vated when the gear selector is moved toR. This setting can be changed in the in MY
CAR menu.
•If there are two cameras installed on the
vehicle*, to switch between cameras, turn
TUNE (at least one of the cameras has to
be active), press CAM repeatedly or use
the center console controls. If the front
camera is on, it overrides the optional park
assist system's visual indicator but there
will still be an audible signal.
Limitations
Even if a fairly small section of the screen image
appears to be obstructed, this may mean that
a relatively large area behind the vehicle is hid-
den and objects there may not be detected
until they are very near the vehicle.
NOTE
Bicycle carriers or other accessories moun-
ted on the tailgate may obstruct the cam-
era's field of view.
Keep in mind
•Keep the camera's lens free of dirt, ice and
snow. Remove ice and snow carefully to
avoid scratching the lens.
•Clean the lens regularly with warm water
and a suitable car washing detergent.
