All Wheel Drive – AWD
4Your Volvo can be equipped with permanent
All Wheel Drive, which means that power is
distributed automatically between the front
and rear wheels. Under normal driving condi-
tions, most of the engine\fs power is directed to
the front wheels. However, if there is any ten-
dency for the front wheels to spin, an electron-
ically controlled coupling distributes power to
the wheels that have the best traction.
NOTEThe message
AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in
the AWD system. A warning light will also
illuminate in the instrument panel. If this
occurs, have the system checked by a
trained and qualified Volvo service techni-
cian.

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-

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
Air conditioningThe vehicle is equipped with Electronic Climate
Control (ECC). The climate control system
cools, heats or dehumidifies the air in the pas-
senger compartment.
NOTE
\b
The air conditioning can be switched
off, but to ensure the best possible cli-
mate comfort in the passenger com-
partment and to prevent the windows
from misting, it should always be on.
\b In warm weather, a small amount of
water may accumulate under the car
when it has been parked. This water is
condensation from the A/C system and
is normal.
Sensor location
\b
The sunlight sensor is located on the top
side of the dashboard.
NOTE The sunlight sensor monitors which side of
the car that is most exposed to sunlight.
This can mean that the temperature may
differ between the right and left-side air
vents, even if the temperatures set for both
sides of the passenger compartment are the
same.
\b
The temperature sensor for the passenger
compartment is located below the climate
control panel.
\b The outside temperature sensor is located
on the door mirror.
\b The humidity sensor
* is located in the inte-
rior rearview mirror.
NOTE Do not cover or block the sensors with
clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works opti-
mally, the side windows, and the optional
moonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-mercially available window washing spray will
also help prevent fogging or misting.
Temporary shut-off of the air
conditioning
The air conditioning is momentarily disen-
gaged during full-throttle acceleration or when
driving uphill with a trailer. This may result in a
temporary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.
Climate system maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
RefrigerantVolvo cares about the environment. The air
conditioning system in your car contains a
CFC-free refrigerant – R134a. This substance
will not deplete the ozone layer. The air condi-
tioning system contains 1.8 lbs (800 g) of
R134a. The systems uses PAG oil.
Passenger compartment filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to
