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 109.
Applying the electric parking brake

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.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.
Operation
G021409
Temporarily switching off Spin control1.
Turn the thumbwheel until the DSTC
menu is shown.
2.
Hold down the RESET button
to toggle
between
DSTC SPIN CONTROL ON or
OFF.
Messages in the information display
DSTC Temporarily OFF – system function
has been temporarily reduced due to high
brake disc temperature. The function is acti-
vated automatically when the brakes have
cooled.
DSTC Service required – the system has
been disabled due to a fault. If this occurs:
1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
If the message remains when the engine is
restarted, drive to an authorized Volvo work-
shop to have the system inspected.

mately 1 mph (1.6 km/h).
NOTE
•A temporary increase in speed by
pressing the accelerator pedal, for less
than 1 minute (e.g. when passing
another car), does not affect the current
cruise control setting. The vehicle will
automatically return to the previously
set speed when the accelerator pedal is
released.
•If one of the cruise control buttons is
kept depressed for more than approx.
1 minute cruise control is disengaged.
The engine must then be switched off in
order to reset cruise control.
Automatic deactivationCruise control is automatically deactivated
temporarily if one of the following occurs:
•If the speed drops below approximately
20 mph (30 km/h).
•When the brake pedal is depressed.
•If the gear selector is moved to position N.
•During wheel spin or wheel lock-up.
•If the vehicle's speed is increased by using
the accelerator pedal for more than
1 minute.
The currently set speed will be saved in the
system's memory.

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.161 Introduction
Collision 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:
•Collision warning warns the driver of the
imminent risk of a collision.
•Brake support helpsthe driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision cannot be avoided.
WARNING
The auto-brake function cannot 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
G017382
Function overview
Visual warning signal, collision risk
Radar sensor
Camera
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

support is activated. Brake support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided, even if pressure on the
brake pedal is light.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes, the auto-brake function is
activated without the driver pressing the brake
pedal. Limited brake force is applied to reduce
the vehicle’s speed when the collision occurs.
WARNING
The auto-brake function cannot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
NOTE
The auto-brake function is always on and
cannot be turned off.
Operation
Some settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 122.
On and offTo switch Collision Warning on or off, go into
the menu Car settings
Collision warning
settings and select On or Off. When the engine
is started, the setting that was selected when
it was switched off will be used.
Activating/deactivating warning signalsThe collision warning system’s audible and vis-
ual signals are activated automatically when
the engine is started if the collision warning
system is activated.
The audible warning signal can be activated/
deactivated by selecting the alternative
On or
Off in Car settingsCollision warning
settings
Warning sound.
Setting a warning distanceThis setting determines the distance at which
the visual and audible warnings are triggered.
Select
Long, Normal or Short under Car
settings
Collision warning settings
Warning distance
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to
Normal.
WARNING
•The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
•Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
•For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 174.
NOTE
•When adaptive cruise control is used,
the warning light and signal will be used
by cruise control, even if they have been
deactivated by the driver.
•In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by going into the menu system at Car
settings
Collision warning settings. See
page 122 for more information on the menu
system.

LimitationsStrong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal in such conditions.
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.
Warnings may not appear if the distance to the
vehicle ahead is very small or if steering wheel
and pedal movements are great, for example,
due to a very active driving style.
WARNING
•In certain situations, the system cannot
provide warnings or warning may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect the
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 stationary or slow-moving vehicles
and may therefore give delayed or no
warnings if your vehicle’s speed is
above approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions.
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 170.
If no warning is given, or if a warning is delayed,
Auto-brake will also not be provided or will be
delayed.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 162. This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 177), and Lane Departure Warning (see
page 180).
NOTE
•To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
•Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.

164* Option/accessory, for more information, see Introduction.
WARNING
•The camera has the same limitations as
the human eye. In other words, its
“vision is impaired” by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera’s
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera’s capacity to detect the side
of a lane or another vehicle.
Fault tracing and actions
If the message Windshield sensors
blocked is displayed, this means that the cam-
era is obscured and cannot detect vehicle or
road marker lines in front of the vehicle.
This, in turn, means that Collision Warning with
Auto-brake, Lane Departure Warning, and
Driver Alert Control will not have full function-
ality.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered
with ice or snow.Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the
camera.
