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
04
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 accel-
eration.
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.

Operation
Selection of level - Sport mode
The DSTC system is always activated - it can-
not be deactivated.
However, the driver can select the Sport mode,
which allows for a more active driving experi-
ence. In Sport mode the system detects
whether the accelerator pedal, steering 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 stabilises the car.
If the driver stops a controlled skid by releasing
the accelerator pedal then the DSTC system
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 display screen's menu
system and locate
My S80
information on the menu system, see
page 144).
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 dese-
lects 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.
