Dynamic Stability Traction Control(DSTC)

The stability system consists of a number of functions designed help reduce wheel spin, counteract skidding, and to generally help improve directional stability.

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 is most active at low speeds.

This is one of DSTC's permanent functions and cannot be switched off.

Spin control (SC) The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.

Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be advisable to temporarily switch off this function for maximum tractive force.

Temporarily switching off Spin control 1. Turn the thumbwheel (1) on the left-side steering wheel lever until the DSTC menu is displayed.
2. Hold down the RESET button (2) to toggle between DSTC SPIN CONTROL ON or OFF.

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.

This is one of DSTC's permanent functions and cannot be switched off.

DSTC-related messages in the text window • TRACTION CONTROL TEMPORARILY OFF – The system has been temporarily switched off due to high brake temperature and will automatically switch on again when the brakes have cooled.
• "ANTI SKID SERVICE REQUIRED" – the system has been automatically disengaged due to a fault. A trained and qualified Volvo service technician should check the system.
