Stability system 

04

154

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

G021409

Temporarily switching off Spin control

1.

Turn the thumbwheel 

 until the 

DSTC

menu is shown.

2.

Hold down the RESET button 

 to toggle

between

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.

Symbols in the instrument panel

If the symbols 

 and 

 are displayed

at the same time, read the message in the
information display.

If the symbol 

 appears alone, it may

appear as follows:

04 Comfort and driving pleasure

 Stability system

04

155

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.

Option/accessory, for more information, see Introduction.

Active chassis (Four C)*

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.

Comfort

Comfort 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.

Sport

In 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.

Advanced

In 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

Chassis settings

Use 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*

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

 Collision warning with Auto-brake*

04

``

*

 

Option/accessory, for more information, see Introduction.

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:

Collision warning warns the driver of the
imminent risk of a collision.

Brake support helpsthe driver brake effi-
ciently in a critical situation.

Auto-brake brakes the vehicle automati-
cally if a collision cannot be avoided.

WARNING

The auto-brake function cannot 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.

Collision warning

The 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 support

If 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-brake

If 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 cannot 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.

Operation

Some settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 120.

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 settings

The current Collision Warning settings can be
checked by going into the menu system at 

Car

Limitations

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal in such conditions.

NOTE

The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.

Warnings may not appear if the distance to the
vehicle ahead is very small or if steering wheel
and pedal movements are great, for example,
due to a very active driving style.

WARNING

In certain situations, the system cannot
provide warnings or warning may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect the
vehicle ahead.

Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.

The sensor system has a limited range
for stationary or slow-moving vehicles
and may therefore give delayed or no
warnings if your vehicle’s speed is
above approximately 45 mph
(70 km/h).

Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions.

The Collision Warning system uses the same
radar sensors as Adaptive Cruise Control. For
more information on the radar sensor and its
limitations, see page 168.

If no warning is given, or if a warning is delayed,
Auto-brake will also not be provided or will be
delayed.

NOTE

If warnings are given too frequently, the
warning distance can be reduced (see
page 160. This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.

The camera’s limitations

The camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 175), and Lane Departure Warning (see
page 178).

NOTE

To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.

Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.
