Electric parking brake
An electric parking brake has the same func-
tion as a manual parking brake.
NOTE
•A faint sound from the parking brake's
electric motor can be heard when the
parking brake is being applied. This
sound can also be heard during the
automatic function check of the parking
brake.
•The brake pedal will move slightly when
the electric parking brake is applied or
released.
Low battery voltageIf the battery voltage is too low, the parking
brake cannot be applied or released. Connect
an auxiliary battery if the battery voltage is too
low, see page 114.
Applying the electric parking brake
Parking brake control
1. Press firmly on the brake pedal.
2. Push the control.

The
symbol in the instrument
panel flashes while the parking brake is
being applied, and glows steadily when
the parking brake has been fully applied.
3. Release the brake pedal and ensure that
the vehicle is at a standstill.
4. When the vehicle is parked, the gear selec-
tor must be in position P.
NOTE
•In an emergency the parking brake can
be applied when the vehicle is moving
by holding in the control. Braking will be
interrupted when the accelerator pedal
is depressed or the control is released.
•An audible signal will sound during this
procedure if the vehicle is moving at
speeds above 6 mph (10 km/h).
Parking on a hill
•If the vehicle is pointing uphill, turn the front
wheels so that they point away from the
curb.
•If the vehicle is pointing downhill, turn the
front wheels so that they point toward the
curb.
The parking brake should also be applied.

Stability system
04
128
Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed to help reduce wheel spin,
counteract 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 brakingone 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.
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 by
allowing 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 S80DSTC 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.

04 Driver support
Adaptive Cruise Control (ACC)*
04
134* Option/accessory, for more information, see Introduction.
Introduction
Adaptive Cruise Control (ACC) is an optional
system designed to assist the driver by main-
taining a set speed or a set time interval 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.
When the driver has set the desired speed and
the time interval to the vehicle ahead, ACC
functions as follows:
•If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the
set speed.
•If ACC's radar sensor detects a slower
moving vehicle in the lane ahead, the sys-
tem will adapt your vehicle's speed to help
maintain the set time interval to the vehicle
ahead. When there are no longer slower
moving vehicles ahead, your vehicle will
accelerate to resume the set speed.
If ACC is switched off completely or in standby
mode and your vehicle comes too close to
another vehicle ahead, the driver will be
warned by the Distance Alert system (see
page 145).
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.

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, which is expressed as a
time interval. For example, you can choose
to remain approximately 2 seconds behind
the vehicle ahead. The actual distance
required to maintain a 2-second interval
will vary according the speed of the vehi-
cles.

138* Option/accessory, for more information, see Introduction.
Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•if the brakes are applied
•if the gear selector is moved to N
•if the driver drives at a speed higher than
the set speed for more than 1 minute.
In this happens, the driver will have to regulate
the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic standby modeAdaptive cruise control is linked to other sys-
tems such as the stability and traction control
system (DSTC). If this system is not functioning
properly, adaptive cruise control is automati-
cally deactivated and will go into standby
mode.
In the event of automatic deactivation, an audi-
ble signal will sound and the message
Cruise
control Cancelled is shown in the display.
The driver must then intervene and adapt thevehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•engine speed (rpm) is too high/low
•the vehicle's speed goes below 18 mph
(30 km/h)3
•the wheels lose traction
•brake temperature is high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactivated
by pressing the
button on the steering
wheel keypad. The vehicle will return to the
most recently set speed.
WARNING
The vehicle may accelerate quickly after has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicleIf your vehicle’s speed is being regulated by
ACC and the driver indicates that he/she would
like to pass the vehicle ahead by using theleft turn signal, ACC can assist by accelerating
briefly.
This function is active at speeds above approx-
imately 45 mph (70 km/h).
WARNING
Please be aware that this function will also
cause the vehicle to accelerate briefly in
certain situations other than passing
another vehicle, for example using the left
turn signal to indicate a lane change or a
turn toward a highway exit at speeds above
approximately 45 mph (70 km/h).
Queue AssistQueue Assist is an added ACC feature that is
linked to your vehicle's automatic transmis-
sion.
Queue Assist consists of the following func-
tions:
•Enhanced speed interval (including when
the vehicle is at a complete stop or is mov-
ing at speed below 18 mph (30 km/h))
•Automatic standby mode when ACC
changes target vehicles
•No automatic braking when at a standstill
•The parking brake is applied automatically
3Does not apply to vehicles equipped with the optional Queue Assist

capacity to avoid a collision. In these condi-
tions, the ABS and DSTC systems provide the
best possible braking effect while helping to
maintain stability.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.
WARNING
•In certain situations, the system cannot
provide warnings or warnings may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian or a vehicle ahead.
•Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
•The sensor system has a limited range
for pedestrians and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions or in poor visibility.
The Collision Warning system uses the same
radar sensors as Adaptive Cruise Control. For
more information on the radar sensor and its
limitations, see page 140.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 156). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
WARNING
•The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
•The driver's actions always have high-
est priority and override the Collision
Warning system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
•When Auto-brake has prevented a col-
lision with a stationary object, your vehi-
cle will remain at a standstill for approx.
1.5 seconds. If your vehicle has been
braked for a moving vehicle ahead, your
vehicle's speed will be reduced to the
same speed as that vehicle's.

Driver Alert System*
04
162* Option/accessory, for more information, see Introduction.
Introduction
The Driver Alert System is designed to help a
driver who may be becoming fatigued or who
is inadvertently leaving the lane.
The Driver Alert System consists of two differ-
ent functions that can be switched on together
or separately.
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW), see
page 165
When one or both of the functions has been
switched on, it is in standby mode and is acti-
vated when the vehicle exceeds a speed of
40 mph (65 km/h).
The function deactivates if the vehicle's speed
goes under 37 mph (60 km/h).
Both functions use a camera that is dependent
on the road/lane being clearly marked by pain-
ted lines on each side.
WARNING
The Driver Alert System does not function in
all situations and is designed to be a sup-
plementary aid. It is not, however, intended
to replace the driver’s attention and judge-
ment.
Driver Alert Control (DAC)–
introduction
This function is intended to alert the driver if
his/her driving becomes erratic, such as if the
driver is distracted or fatigued.
NOTE
The camera has certain limitations, see
page 140.
A camera monitors the painted lines marking
the lane in which the vehicle is traveling and
compares the direction of the road with the
driver’s movements of the steering wheel. The
driver is alerted if the vehicle does not follow
the lane smoothly.DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
WARNING
•DAC is not intended to extend the dura-
tion of driving. Always plan breaks at
regular intervals to help remain alert.
•In certain cases, fatigue may not affect
the driver’s behavior. In situations of
this type, no warning will be provided.
Therefore, it is important to take breaks
at regular intervals, regardless of
whether or not DAC has given a warn-
ing.
LimitationsIn certain situations, DAC may provide warn-
ings even if the driver’s driving pattern has not
become erratic.
•if the driver is testing the LDW function
•in strong crosswinds
•on grooved road surfaces.
