Active chassis system–Four C
04
157 Active chassis (Four C)–option
Active chassis, Four-C (Continuously Con-
trolled Chassis Concept), regulates the cha-
racteristics of the shock absorbers so that the
car's driving characteristics can be adjusted.
There are three settings: Comfort, Sport and
Advanced.ComfortComfort mode offers a somewhat softer ride
and the transmission shifts gears at lower rpm.
This mode is particularly suitable for long-dis-
tance highway driving. The indicator light in the
button will be on when this mode is selected.SportIn this mode, the vehicle's body sway is
reduced during cornering and steering
response is more immediate. The transmission
shifts up at higher rpm for sportier driving. The
indicator light in the button will be on to indi-
cate that Sport mode has been selected.AdvancedIn this mode, body sway in curves is minimal
and steering response is very direct. Gear shift-
ing is done at high rpm in each gear for
dynamic and active driving.
Operation

Chassis settingsUse the buttons in the center console to
change setting. The setting in use when the
engine is switched off is activated the next time
the engine is started.Speed-dependent steering force
(option)Steering force increases with the speed of the
vehicle to give the driver enhanced sensitivity.
At low speed the vehicle is easy to steer in
order to facilitate parking, etc.
Steering force can be changed under Car
settings
Steering force level. For a
description of the menu system, see
page 120.
NOTE
This steering force level menu function can-
not be accessed when the vehicle is in
motion.

04 Comfort and driving pleasureCollision warning with Auto-brake (option)
04160
IntroductionCollision Warning with Auto-brake is designed
to assist the driver if there is a risk of a collision
with the vehicle ahead, if that vehicle is at a
standstill or moving in the same direction as
your vehicle. Auto-brake helps reduce the col-
lision speed.
Collision Warning consists of the following
three functions:1. Collision warningThe driver is warned of the imminent risk of a
collision.2. Brake supportThis helps the driver brake efficiently in a criti-
cal situation.3. Auto-brakeThis function brakes the vehicle automatically
if a collision cannot be avoided.
WARNING
The auto-brake function connot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
WARNING
•
The collision warning system does not
work in all driving situations, and traffic,
weather and road conditions.
•
The collision warning system is not
designed to detect pedestrians.
•
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 use.
•
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 components must only be per-
formed by a trained and qualified Volvo
technician.

Function overview
Visual warning signal, collision riskRadar sensorCamera
Collision warningThe radar sensor and the camera work
together to detect stationary vehicles and vehi-
cles that are moving in the same direction as
your vehicle. If there is a risk of collision, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 5 mph (7 km/h).Brake supportIf the risk of collision continues to increase after
the collision warning has been given, brake

04 Comfort and driving pleasureAdaptive Cruise Control–ACC (option)
04166
IntroductionAdaptive Cruise Control (ACC) is an optional
system designed to assist the driver by main-
taining a set speed or a set distance to the
vehicle ahead. It is primarily intended for use
on long straight roads in steady traffic, such as
on highways and other main roads.
WARNING
•
Do not use the adaptive cruise control
system in demanding driving conditions
such as city traffic, winding roads, at
intersections, on slippery surfaces, in
poor visibility, heavy rain, etc.
•
Maintenance of cruise control compo-
nents must only be performed by an
authorized Volvo workshop.
WARNING
•
Adaptive cruise control cannot cover all
driving situations and traffic, weather
and road conditions. The Function sec-
tion provides information about limita-
tions that the driver must be aware of
before using the adaptive cruise con-
trol.
•
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.
Function

Function overview
Warning light, braking by driver requiredControlsRadar sensor in front grille
Adaptive cruise control consists of:
•
A cruise control system to maintain a set
speed
•
A system to maintain a set distance to the
vehicle ahead (expressed as a time inter-
val. For example, you can choose to
remain approximately 2 seconds behind
the vehicle ahead).

Adaptive Cruise Control–ACC (option)
04``167
WARNING
•
Adaptive cruise control is not a collision
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 slow moving or stationary vehicles.
The distance to the vehicle ahead (in the same
lane) is measured by a radar sensor. Your vehi-
cle's speed is regulated by acceleration and
braking. The brakes may emit a sound when
they are being modulated by the adaptive
cruise control system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the
brakes. Do not rest your foot under the
brake pedal.The adaptive cruise control system is designed
to follow the vehicle ahead of you in the same
lane, at a set time interval.
If the radar sensor has not detected a vehicle
ahead, the system will then attempt to maintain
the set speed. This is also the case if the speedof the vehicle ahead exceeds the speed that
you have set.
The adaptive cruise control system is designed
to smoothly regulate speed. However, the
driver must apply the brakes in situations that
require immediate braking. This applies when
there are great differences in speed between
vehicles, or if the vehicle ahead brakes sud-
denly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 169.Adaptive cruise control can only be activated
at speeds above 20mph (30 km/h). If speed
falls below 20 mph (30 km/h) or if engine speed
(rpm) becomes too low, adaptive cruise control
disengages and will no longer modulate the
brakes. In situations when adaptive cruise con-
trol cannot be activated
Cruise Control
Unavailable
is shown in the display, see
page 171.
WARNING
When adaptive cruise control disengages,
the brakes will not be modulated automati-
cally. The driver must assume full control
over the vehicle.Warning light-driver braking requiredAdaptive cruise control has a braking capacity
that is equivalent to approximately 30% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can pro-
vide, if the driver does not apply the brakes, an
audible signal will sound and a red warning
light will illuminate in the windshield to alert the
driver to react.
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
Cruise control only warns of vehicles
detected by the radar sensor, see
page 169. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.

04 Comfort and driving pleasureBlind Spot Information System (option)
04184
Introduction
G021426
BLIS cameraIndicator lightBLIS symbol
The Blind Spot Information System (BLIS) is an
information system that indicates the presence
of another vehicle moving in the same direction
as your vehicle in the side-view mirror's "blind
area."CAUTION
The BLIS system should only be repaired by
a trained and qualified Volvo service tech-
nician.
WARNING
•
BLIS is an information system, NOT a
warning or safety system.
•
BLIS does not eliminate the need for
you to visually confirm the conditions
around you, and the need for you to turn
your head and shoulders to make sure
that you can safely change lanes.
•
As the driver, you have full responsibility
for changing lanes in a safe manner.
The system is based on digital camera tech-
nology. The cameras are located beneath the
side-view mirrors.
When one (or both) of the cameras have
detected a vehicle in the blind area (up to
approximately 10 ft. (3 meters) from the side of
your vehicle, and up to approximately 31 ft.
(9.5 meters) behind the side-view mirror), see
the illustration, the indicator light in the door
panel illuminates. The light will glow continu-
ously to alert the driver of the vehicle in the
blind area.
NOTE
The door panel indicator light illuminates on
the side of the vehicle where the system has
detected another vehicle. If your vehicle is
passed on both sides at the same time, both
lights will illuminate.BLIS has an integrated function that alerts the
driver if a fault should occur with the system.
For example, if one or both of the system's
cameras are obscured, a message (see the
table on page 187) will appear in the informa-
tion display in the instrument panel. If this
occurs, clean the camera lenses. If necessary,
the system can be temporarily switched off (for
instructions, see page 186).

Roof loadsUsing load carriersLoad carriers are available as Volvo accesso-
ries. Observe the following points when in use:•
To avoid damaging your vehicle and to
achieve maximum safety when driving, we
recommend using the load carriers that
Volvo has developed especially for your
vehicle.
•
Volvo-approved removable roof racks are
designed to carry the maximum allowable
roof load for this vehicle: 220 lbs (100 kg).
For non-Volvo roof racks, check the man-
ufacturer's weight limits for the rack.
•
Never exceed the rack manufacturer's
weigh limits and never exceed the maxi-
mum rated roof load of 220 lbs (100 kg).
•
Avoid single-point loads. Distribute loads
evenly.
•
Place heavier cargo at the bottom of the
load.
•
Secure the cargo correctly with appropri-
ate tie-down equipment.
•
Check periodically that the load carriers
and load are properly secured.
•
Remember that the vehicle's center of
gravity and handling change when you
carry a load on the roof.
•
The vehicle's wind resistance and fuel con-
sumption will increase with the size of the
load.
•
Drive smoothly. Avoid rapid starts, fast
cornering and hard braking.
