Traction control - TC

This function is designed to help reduce wheel spin 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). TC monitors and
compares the rotational speed of the drive wheels. If one of the drive wheels shows a tendency to spin,
the difference in speed is immediately detected.
TC is most active at low speeds, and a pulsating sound will be audible when the system is regulating
wheel spin. This is quite normal.
This function cannot be disabled.

Spin control - SC

The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is
accelerating. This is done by temporarily reducing engine torque to the drive wheels, which helps
improve tractive force.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose
sand, it may be advisable to temporarily disable this function for maximum tractive force. This is done
by pressing the STC/DSTC button (see the illustration on

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 tendency to skid or slide laterally. A pulsating sound will be audible
when the function is active, which is quite normal. If you apply the brakes while this function is active,
the brake pedal will feel stiffer than usual.
This function cannot be disabled.
