Spin Control (SC)
The SC function is designed to help prevent the
drive wheels from spinning while the vehicle is
accelerating.
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 ten-
dency to skid or slide laterally.
Corner Traction Control (CTC)
CTC compensates for understeering and helps
provide additional stability when accelerating
through a curve by preventing the inside wheel
from spinning. This is particularly useful when
accelerating on a curving highway 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 shifting mode or while
using the engine's braking function on a slippery
surface. If the engine were to stop, power steer-
ing would not function, making the vehicle more
difficult to steer.
Trailer Stability Assist (TSA)
The TSA helps stabilize a vehicle that is towing a
trailer when the vehicle and trailer have begun to
sway. See Trailer Stability Assist (TSA) (p. 287)
for more information.
This system is automatically deactivated if the
driver selects Sport mode.

Operation
Sport mode
The stability system is always activated and can-
not be switched off.
However, the driver can select
Sport mode, which offers more
active driving characteristics.
Sport mode can be selected in
the MY CAR menus, see My
Car – introduction (p. 71).
In Sport 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
ESC is activated.
Under certain circumstances, such as when driv-
ing 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 accelerator
pedal, ETC will also activate to help stabilize the
vehicle.
To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is
switched off. ETC will return to normal mode
when the engine is restarted.
