Stability system
The car is equipped with DSTC (Dynamic Stability and Traction Control). This system consist of the following
functions:
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.
Disabling the spin control function:
This is done in the menu system, and will be indicated by a text messages in the information display.
Turn control (A) on the left steering wheel lever until the DSTC menu is displayed.
Press and hold down the reset button (B) until DSTC SPIN CONTROL OFF or DSTC ON is displayed.
The anti-spin function will be automatically reactivated when the engine is started.
WARNING!
The car's handling and stability characteristics will be altered with the spin control function disabled.
Active yaw control - AYC
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
