DSTC – Stability and traction control system
General information on DSTC
The stability and traction control system,
DSTC (Dynamic Stability & Traction Control)
helps the driver to avoid skidding and
improves the car's traction.
The activation of the system during braking
may be noticed as a throbbing sound. The
car may accelerate slower than expected
when the accelerator pedal is depressed.
Active Yaw Control

The function limits the driving and brake force
of the wheels individually in order to stabilise
the car.
Spin Control
The function prevents the driving wheels from
spinning against the road surface during
acceleration.
Traction control system
The function is active at low speed and trans-
fers power from the driving wheel that is spin-
ning to the one that is not.
Trailer stabiliser - TSA
The function serves to stabilise the car and
trailer combination if it begins to snake, see
page 329.

selects Sport mode.
Operation
Selection of level - Sport mode
The DSTC system is always activated - it
cannot be deactivated.
However, the driver can select the Sport
mode, which allows for a more active driving
experience. In Sport mode the system
detects whether the accelerator pedal, steer-
ing wheel movements and cornering are more
active than in normal driving and then allows
controlled skidding with the rear section up to
a certain level before it intervenes and stabil-
ises the car.
If the driver stops a controlled skid by releas-
ing the accelerator pedal then the DSTC sys-
tem intervenes and stabilises the car.
With Sport mode, maximum traction is
obtained if the car has become stuck, or

when driving on a loose surface - e.g. sand or
deep snow.
Proceed as follows to select Sport mode:
1. Press the centre console button MY CAR
and search in the screen's menu system
and locate My S80 DSTC. (For infor-
mation on the menu system, see
page 209).
2. Uncheck the box and back out of the
menu system with EXIT.
> The system then allows a more sporty
driving style.
The Sport mode is active until the driver
deselects it or until the engine is switched off
- after the engine is started the next time the
DSTC system is back in its normal mode
again.
