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.

Introduction
1
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
G017426
•
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 instru-
ment panel illuminates and a message is
displayed 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 HDCHDC 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
1HDC is only available on the XC70, on which it is standard equipment.

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.
NOTE
Engine response to pressure on the accel-
erator pedal may be slightly slower than
normal when HDC is activated.

Stability system
04``155 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

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.

If the symbol
appears alone, it may
appear as follows:
•
If the symbol flashes, this indicates that the
stability system is actively functioning to
help counteract wheel spin and/or a skid.
•
If the symbol remains on for approximately
2 seconds after the engine has been
started, this indicates that the system is
performing a self-diagnostic test.WARNING
The stability system is intended to help
improve driving safety. It supplements, but
can never replace, the driver's judgment
and responsibility when operating the vehi-
cle. Speed and driving style should always
be adapted to traffic and road conditions.

Active chassis system–Four C
04
157 Active chassis (Four C)–option
Active chassis, Four-C (Continuously Con-
trolled Chassis Concept), regulates the cha-
racteristics of the shock absorbers so that the
car's driving characteristics can be adjusted.
There are three settings: Comfort, Sport and
Advanced.ComfortComfort mode offers a somewhat softer ride
and the transmission shifts gears at lower rpm.
This mode is particularly suitable for long-dis-
tance highway driving. The indicator light in the
button will be on when this mode is selected.SportIn this mode, the vehicle's body sway is
reduced during cornering and steering
response is more immediate. The transmission
shifts up at higher rpm for sportier driving. The
indicator light in the button will be on to indi-
cate that Sport mode has been selected.AdvancedIn this mode, body sway in curves is minimal
and steering response is very direct. Gear shift-
ing is done at high rpm in each gear for
dynamic and active driving.
Operation
G021410
Chassis settingsUse the buttons in the center console to
change setting. The setting in use when the
engine is switched off is activated the next time
the engine is started.Speed-dependent steering force
(option)Steering force increases with the speed of the
vehicle to give the driver enhanced sensitivity.
At low speed the vehicle is easy to steer in
order to facilitate parking, etc.
Steering force can be changed under Car
settings
Steering force level. For a
description of the menu system, see
