wheel (see the right-pointing beam in the illus-
tration).This function is activated automatically when
the engine is started and can be deactivated/
reactivated by pressing the ABL button
in the center console. This button
lights up when the ABL function is activated,
and will flash if there is a fault in the system.NOTE
This function is only active in twilight or dark
conditions, and only when the vehicle is in
motion.Parking lights

Headlight control in position for parking lightsThe front and rear parking lights can be turned
on even when the ignition is switched off.Turn the headlight control to the center posi-
tion (the license plate lighting comes on at the
same time).
The lighting also comes on when the trunk is
opened in order to alert anyone traveling
behind your vehicle.
Brake lightsThe brake lights come on automatically when
the brakes are applied.Emergency brake lights (EBL)Emergency Brake Lights, EBL, activate in the
event of sudden braking or if the ABS system
is activated. This function causes an additional
taillight on each side of the vehicle to illuminate
to help alert vehicles traveling behind.
The EBL function activates if:•
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.

03 Your driving environmentBrakes
03112
Brake systemThe brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in the reservoir.
NOTE
Press the brake pedal hard and maintain
pressure on the pedal – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a brake system message is
shown in the information display:
DO NOT
DRIVE
. Have the vehicle towed to a trained
and qualified Volvo service technician and
have the brake system inspected.
Power brakes function only when the
engine is runningThe 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, the brake
pedal must be pressed approximately five
times harder than usual to make up for the lack
of power assistance. This can happen for
example when towing your vehicle or if the
engine is switched off when the vehicle is roll-
ing. The brake pedal feels harder than usual.Water on brake discs and brake pads
affects brakingDriving 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 the
brakes 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 usuallyslower, 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 systemThe 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 25 mph
(40 km/h). The brake pedal will pulsate several
times and a sound may be audible from the
ABS control module. This 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.
NOTE
•
When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•
When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

04 Comfort and driving pleasureStability system
04154
IntroductionThe 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

Collision warning with Auto-brake (option)
04``159 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: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
G017382
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

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 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.
NOTE
The auto-brake function is always on and
cannot be turned off.OperationSome settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 120.
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

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 172.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 120 for more information on the menu
system.

04 Comfort and driving pleasureAdaptive Cruise Control–ACC (option)
04166
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 168.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 170.
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 168. 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 pleasureAdaptive Cruise Control–ACC (option)
04168
WARNING
•
Only use a time interval that is suitable
in current traffic conditions.
•
A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is acti-
vated, see page 172 .Deactivating and resuming settingsCruise control is deactivated, either with a
short press on
, or by action taken by the
driver, such as braking, etc. The set speed, for
example 55 mph, is then shown in parenthe-
ses. Speed and time interval are resumed by
pressing
.
WARNING
There may be a significant increase in speed
after the
button has been pressed.
A short press on
in standby mode or a long
press in active mode deactivates cruise con-trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time
is pressed.
Deactivation due to action by the driverACC is deactivated:•
when the brakes are applied
•
if the gear selector is moved to N
•
if the accelerator pedal is depressed for an
extended period.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 deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cruise Control
Canceled
is shown in the display. The drivermust then intervene and adapt the vehicle's
speed to the surrounding traffic.
Automatic deactivation may be caused if:
•
the vehicle's speed falls below 20 mph
(30 km/h)
•
the wheels lose traction or if the anti-lock
brake system (ABS) is activated
•
brake temperature is high
•
engine speed (rpm) is too low
•
the radar sensor is obstructed by, for
example, wet snow or rain.
The radar sensor and its limitationsThe radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.The radar sensor's capacity to detect vehicles
ahead is impeded:
