112 Brake system
The 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 running
The 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 braking
Driving 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 usually slower, 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
\b
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.
\b 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.Symbols in the instrument panel Symbol Specification

inspected.

03 Your driving environmentHill Descent Control (HDC) 03
114 Introduction
Normally, when the accelerator pedal is
released while driving down hills, the vehicle\fs
speed slows as the engine runs at lower rpm
(the normal engine braking effect). However, if
the downhill gradient becomes steeper and if
the vehicle is carrying a load, speed increases
despite the engine braking effect. In this situa-
tion, the brakes must be applied to reduce the
vehicle\fs speed.
HDC is a type of automatic engine brake and
makes it possible to increase or decrease the
vehicle\fs speed on downhill gradients using
only the accelerator pedal, without applying
the brakes. The brake system functions auto-
matically to maintain a low and steady speed.
HDC is particularly useful when driving down
steep hills with rough surfaces, and where the
road may have slippery patches.
WARNING
HDC does not function in all situations, and
is a supplementary braking aid. The driver
has full responsibility for driving in a safe
manner. Function
\b
HDC can be switched on and off with the
button in the center console. An indicator
light in the button illuminates when HDC is
activated.
\b The indicator light in the instru-
ment panel illuminates and a message is
displayed when the system is controlling
the vehicle\fs speed.
\b HDC only functions when
first or reverse
gears are selected (1 will be shown in the
instrument panel display when first gear is
selected).
NOTE HDC cannot be activated if the gear selector
is the D position. Using HDC
HDC allows the car to roll forward at a maxi-
mum speed of 6 mph (10 km/h), and 4 mph
(7 km/h) in reverse. However, the accelerator
pedal can be used to select any speed that is
possible in first or reverse gears. When the
accelerator pedal is released, speed is quickly
reduced again to 6 mph (10 km/h) or 4 mph
(7 km/h), depending on the gear selected,
regardless of the hill\fs gradient. It is not nec-
essary to apply the brakes.
\b
The brake lights illuminate automatically
when HDC is controlling the vehicle\fs
speed.
\b The driver can slow or stop the vehicle at
any time by applying the brakes.
HDC is deactivated when:
\b The button on the center console is
pressed
\b A gear higher than first gear is selected
\b D is selected on vehicles with an automatic
transmission
HDC can be deactivated at any time. If this is
done while driving down a steep hill, the sys-
tem\fs braking effect will decrease gradually. G031964

116 Electric parking brake
An electric parking brake has the same func-
tion as a manual parking brake.
NOTE
\b
A faint sound from the parking brake\fs
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.
\b 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 107.
Applying the electric parking brake Parking brake control
1. Press firmly on the brake pedal.
2. Push the control.
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.
The symbol in the instrument panel
flashes while the parking bake is being applied,
and glows steadily when the parking brake has
been fully applied.NOTE \b
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.
\b 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
\b
If the vehicle is pointing uphill, turn the front
wheels so that they point away from the
curb.
\b If the vehicle is pointing downhill, turn the
front wheels so that they point toward the
curb. G021354

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\fs 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\fs 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\fs handling and stability characteris-
tics will be altered if the spin control function
has been disabled.
Operation
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 \b
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.
\b 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.

temporarily if one of the following occurs:
\b
If the speed drops below approximately
20 mph (30 km/h).
\b When the brake pedal is depressed.
\b If the gear selector is moved to position N.
\b During wheel spin or wheel lock-up.
\b If the vehicle\fs speed is increased by using
the accelerator pedal for more than 1
minute.

* Option/accessory, for more information, see Introduction.
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 \b
The collision warning system does not
work in all driving situations, and traffic,
weather and road conditions.
\b The collision warning system is not
designed to detect pedestrians.
\b 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.
\b 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\fs 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.
\b Maintenance of the collision warning
system components must only be per-
formed by a trained and qualified Volvo
technician. Function

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 G032740
