Traction Control (TC)
Stability system – operation
This function is designed to help reduce
wheel spin at low speeds 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).
Operation
Trailer Stability Assist (TSA)1
Sport mode
The stability system is always activated and
cannot be switched off.
The TSA helps stabilize a vehicle that is tow-
ing a trailer when the vehicle and trailer have
begun to sway. See Trailer Stability Assist
(TSA) (p. 284) for more information.
Spin Control (SC)
However, the driver can
select Sport mode, which
offers more active driving
characteristics.
The SC function is designed to help prevent
the drive wheels from spinning while the vehi-
cle is accelerating.
This system is automatically deactivated if the
driver selects Sport mode.
Active Yaw Control (AYC)
Sport mode can be selected
in the MY CAR menus, see
My Car – introduction (p. 76).

pedal and steering wheel for sportier driving
by allowing more lateral movement of the rear
wheels before ESC is activated.

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.
•
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.
CTC is most effective if the stability system's
Sport mode is selected. See the section
about Sport mode.
If the driver releases pressure on the acceler-
ator pedal, ETC will also activate to help sta-
bilize the vehicle.
