Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed to 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 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.
Corner Traction Control – CTC
CTC compensates for understeering and
helps provide additional stability when accel-
erating through a curve by preventing the
inside wheel from spinning. This is particularly
useful when accelerating on a curving high-
way on-ramp.
CTC is most effective if the stability system's
Sport mode is selected. See the section
about Sport mode.
Engine Drag Control (EDC)
EDC helps keep the engine running if the
wheels show a tendency to lock, e.g., when
shifting down in the Geartronic manual shift-
ing mode or while using the engine's braking
function on a slippery surface. If the engine
were to stop, power steering would not func-
tion, making the vehicle more difficult to
steer.
Trailer Stability Assist – TSA
Trailer Stability Assist helps stabilize a vehicle
that is towing a trailer when the vehicle and
trailer have begun to sway. See page 301 for
more information.
This system is automatically deactivated if the
driver selects
Sport
mode.
Operation
Sport mode
The stability system is always activated and
cannot be switched off.
However, the driver can select
Sport
mode,
which offers more active driving characteris-
tics. In this mode, the engine management
system monitors movement of the accelerator
pedal and steering wheel for sportier driving
by allowing more lateral movement of the rear
wheels before DSTC is activated.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily use
Sport
mode for maximum
tractive force.
If the driver releases pressure on the acceler-
ator pedal, DSTC will also activate to help
stabilize the vehicle.
To switch to
Sport mode:
1. Press the
My Car
button in the center
console control panel and select My S60
DSTC
in the menu.
