Center display overview (p. 109) Table of settings in the center
display
The center display's Settings menu has a num-
ber of main categories and sub-categories that
contain settings and information for many of the
vehicle's features and functions.
There are seven main categories:
My Car,
Sound, Navigation, Media, Communication,
Climate and System.
Each category, in turn, contains a number of sub-
categories and possible settings. The table below
shows the first level of sub-categories. The possi-
ble settings for a function or an area are descri-
bed in more detail in their respective sections of
the Owner's Manual.
Some settings are personal, which means that
they can be saved to a Driver Profiles. Others
are global, which means that they are not linked
to a driver profile.

Note: The ESC system is not deactivated in this mode, but has partially reduc\
ed functionality. ESC
Temporarily off
The ESC system's functionality has been temporarily reduced due to hi\
gh brake system temperatures. The

288Managing Cruise Control speed
Cruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed Note: This illustration is general and details may vary
depending on model.
For vehicles with only CC
–
Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing and
holding them:
• Press briefly: Press briefly: each press
changes the speed in +/- 1 mph
(+/- 1 km/h) increments.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed. •
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
For vehicles with both CC and ACC
– Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing and
holding them:
• Press briefly: Press briefly: each press
changes the speed in +/- 5 mph
(+/- 5 km/h) increments.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver can temporarily disengage the Cruise Con-
trol braking function.
To disengage CC:
– Press the accelerator pedal about halfway
down and then release it.
>

Cruise Control will automatically disen-
gage the automatic brake function and
speed will only be reduced using the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode 30

DRIVER SUPPORT

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera-
tion and deceleration will be smoother than in
other drive modes to help provide optimal fuel
efficiency and reduced environmental impact.
Because of this, the vehicle's actual speed may
be slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's
acceleration and deceleration will be faster and
more immediate than in other drive modes.

Control in standby mode
Cruise Control (CC 31
) can be temporarily put
into standby mode and then reactivated.
Deactivating and putting Cruise Control
in standby mode Note: This illustration is general and details may vary
depending on model.
To put Cruise Control in standby mode:
–
Press the button on the steering wheel
(2).
>

The Cruise Control markings and symbols
will change from WHITE to GRAY, indicat-
ing that Cruise Control is temporarily
deactivated and the driver needs to con-
trol the vehicle's speed.
Standby mode due to action by the driver
Cruise Control will be temporarily deactivated and
put in standby mode if:
• the brakes are applied
• the gear selector is moved to N
• the vehicle is driven faster than the set
speed for more than 1 minute
The driver must then control the vehicle's speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Automatic standby mode
Cruise Control will be temporarily deactivated and
put in standby mode if:
• the wheels lose traction
• the engine speed (rpm) is too low/high
• the temperature in the brake system
becomes too high
• the vehicle's speed goes below 30 km/h
(20 mph).
The driver must then control the vehicle's speed.

||DRIVER SUPPORT

WARNING
•
The Adaptive Cruise Control function is
supplementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
• The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
• Adaptive Cruise Control is not a substi-
tute for the driver's attention and judg-
ment. The driver is always responsible for
ensuring the vehicle is driven in a safe
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.
NOTE Depending on market, this function may be
either Standard or Optional.
Adaptive Cruise Control regulates speed by
accelerating and braking. It is normal for the brakes to emit a slight sound when they are
being used to adjust speed.
Adaptive Cruise Control always attempts to regu-
late speed smoothly. The driver must apply the
brakes in situations requiring immediate braking.
For example, when there are great differences in
speed between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the radar
sensor, braking may occur unexpectedly or not at
all.
Adaptive Cruise Control is designed to follow a
vehicle ahead in the same lane and maintain a
time interval to that vehicle set by the driver. If the
radar sensor does not detect a vehicle ahead, it
will instead maintain the speed set by the driver.
This will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow another
vehicle at speeds from a standstill up to
200 km/h (125 mph).
WARNING •
Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible and must intervene if the sys-
tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brake
for people or animals and does not brake
for small vehicles, such as bikes and
motorcycles. Similarly, it does not brake
for low trailers, oncoming, slow-moving or
stationary vehicles and objects.
• Do not use Adaptive Cruise Control in
demanding situations, such as in city traf-
fic, at intersections, on slippery surfaces,
with a lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.
CAUTION Maintenance of Adaptive Cruise Control com-
ponents may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.
