Stability system
Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of functions designed help reduce
wheel spin, counteract 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 stability, 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 maximum tractive force.
WARNING
The car's handling and stability characteristics will be altered if the spin control function has been disabled.
Operation

Temporarily switching off Spin control
1. 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 activated automatically when the brakes have cooled.
DSTC Service required - the system has been disabled due to a fault. If this occurs:

Stability system
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 workshop 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:
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 vehicle. Speed and driving style should always be adapted to traffic
and road conditions.

Adjusting the set speed
After a speed has been set, it can be increased or decreased by using the
or buttons.
Press and hold down or until the vehicle reaches the desired speed. This will become the set speed when the
button is released.
Press or for approximately a half second and release the button to increase or decrease vehicle speed by
approximately 1 mph (1.6 km/h).
NOTE
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.
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.
Automatic deactivation
Cruise control is automatically deactivated temporarily if one of the following occurs:
If the speed drops below approximately 20 mph (30 km/h).
When the brake pedal is depressed.
If the gear selector is moved to position N.
During wheel spin or wheel lock-up.
If the vehicle's speed is increased by using the accelerator pedal for more than 1 minute.
The currently set speed will be saved in the system's memory.

Cruise control
Temporary deactivation
The driver can temporarily deactivate cruise control by pressing 0. The saved speed is shown in brackets in the
information display.
Resume set speed
If cruise control has been deactivated temporarily, it can be reactivated by pressing
. The vehicle's speed returns to
the most recently set speed.
WARNING
There may be a significant increase in speed after the
button has been pressed.
Deactivation
Cruise control is disengaged with CRUISE , by putting the gear selector in Neutral, or by switching off the engine. The
set speed is cleared.
WARNING
Cruise control should not be used in heavy traffic or when driving on wet or slippery roads. Cruise control may not

The set speed, for example 55 mph, is then shown in parentheses. Speed and time interval are resumed by pressing .
WARNING
There may be a significant increase in speed after the
button has been pressed.
A short press on
in standby mode or a long press in active mode deactivates ACC.
The set speed is then cleared and cannot be resumed.
When ACC is activated, the vehicle's speed increases by approximately 1 mph (1 km/h) each additional time
is
pressed.
Deactivation due to action by the driver
ACC is deactivated:
when the brakes are applied
if the gear selector is moved to N
if the accelerator pedal is depressed for an extended period.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passing another vehicle, ACC is deactivated
temporarily and is reactivated when the pedal is released.
Automatic deactivation
Adaptive cruise control is linked to other systems such as ABS, the stability and traction control system (DSTC) and
the Distance Alert system. If any of these systems are not functioning properly, adaptive cruise control is automatically
deactivated.
In the event of automatic deactivation a signal will sound and the message Cruise Control Canceled is shown in the
display. The driver must then intervene and adapt the vehicle's speed to the surrounding traffic.
Automatic deactivation may be caused if:
the vehicle's speed falls below 20 mph (30 km/h)
the wheels lose traction or if the anti-lock brake system (ABS) is activated
brake temperature is high
engine speed (rpm) is too low
the radar sensor is obstructed by, for example, wet snow or rain.

Adaptive Cruise Control-ACC
The radar sensor and its limitations
The radar sensor is used by both Adaptive Cruise Control and the Collision Warning System with Auto-brake (see
page 166
). It is designed to detect cars or larger vehicles driving in the same direction as your vehicle.
