Spin Control (SC)
The SC function is designed to help prevent the drive wheels from spinning while the vehicle isaccelerating.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one ormore 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 acceleratingthrough a curve by preventing the inside wheelfrom spinning. This is particularly useful whenaccelerating 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 downin the Geartronic manual shifting mode or whileusing the engine's braking function on a slipperysurface. If the engine were to stop, power steer-ing would not function, making the vehicle moredifficult to steer.
Trailer Stability Assist (TSA)
The TSA helps stabilize a vehicle that is towing a trailer when the vehicle and trailer have begun tosway. 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 allowingmore lateral movement of the rear wheels beforeESC is activated. Under certain circumstances, such as when driv- ing with snow chains, or driving in deep snow orloose 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 thevehicle. 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 modewhen the engine is restarted.

Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval to the vehi-cle ahead.

• Press and hold the
button; the symbol in
the instrument panel will switch from

.
> This activates the standard cruise control function (see Cruise control (CC) – introduc- tion (p. 173)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automatically
maintain a set distance to a vehicle ahead.
• Only the set speed will be maintained andthe driver will have to apply the brakeswhen needed.
Switching from CC to ACC
Switch off cruise control by pressing once or
twice as needed according to the instructions in
