121 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 113.
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 bake 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.

Releasing the electric parking brake
Parking brake control
Manual release1. Fasten the seat belt.
2. Insert the remote key in the ignition slot (or
press the START/STOP ENGINE button
on vehicles with the optional keyless drive).
3. Press firmly on the brake pedal.
4. Pull the parking brake control.
Automatic release1. Start the engine.
NOTE
•For safety reasons, the parking brake is
only released automatically if the engine
is running and the driver is wearing a seat
belt.
•The electric parking brake will be
released immediately when the acceler-
ator pedal is pressed and the gear selec-
tor is in position D or R.
2. Fasten the seat belt.
3.
Move the gear selector to position D or R
and press the accelerator pedal. The park-
ing brake will release when the vehicle
begins to move.
Heavy load uphillA heavy load, such as a trailer, can cause the
vehicle to roll backward when the parking
brake is released automatically on a steep
incline. To help avoid this:
1. Keep the electric parking brake lever
pushed in with the left hand while shifting
into Drive with the right.
2. While pressing the throttle pedal to pull
away, release the parking brake lever only
after the vehicle begins to move.
Symbols
SymbolSpecification
Read the message in the infor-
mation display
A flashing symbol indicates that
the parking brake is being
applied. If the symbol flashes in
any other situation then this
means that a fault has arisen.
Read the message on the infor-
mation display.
Messages
Park brake not fully released – A fault is pre-
venting the parking brake from being released.
Try to apply the parking brake and release it
several times. If the problem persists, contact

an authorized Volvo workshop. If you drive off
with this error message showing, a warning
signal sounds.
Parking brake not applied – A fault is pre-
venting the parking brake from being applied.

several times. If the problem persists, contact
an authorized Volvo workshop. If you drive off

Parking brake Service required – A fault has
occurred. Try to apply and release. Contact a
Volvo workshop if the fault remains.
WARNING
If the vehicle must be parked before the fault
has been corrected, always put the gear
selector in P and turn the wheels so that
they point away from the curb if the vehicle
is pointing uphill or toward the curb if it is
pointing downhill.

Hill Descent Control (HDC)*
03
124* Option/accessory, for more information, see Introduction.
Introduction
Normally, when the accelerator pedal is
released while driving down hills, the vehicle's
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's speed.
HDC is a type of automatic engine brake and
makes it possible to increase or decrease the
vehicle's 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
•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.
•The indicator light in the instrument
panel illuminates and a message is dis-
played when the system is controlling the
vehicle's speed.
•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's gradient. It is not nec-
essary to apply the brakes.
•The brake lights illuminate automatically
when HDC is controlling the vehicle's
speed.
•The driver can slow or stop the vehicle at
any time by applying the brakes.
HDC is deactivated when:
•The button on the center console is
pressed
•A gear higher than first gear is selected
•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's braking effect will decrease gradually.
