04 Comfort and driving pleasure Stability system Introduction The Dynamic Stability and Traction Control system (DSTC) consists of a number of functions designed help reduce wheel spin, counteract skidding, and to generally help improve directional stability. 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 until the DSTC menu is shown. 2. Hold down the RESET button to toggle between DSTC SPIN CONTROL ON or OFF. CAUTION A pulsating sound will be audible when the system is actively operating and is normal. 04 Messages in the information display DSTC Temporarily OFF - system function has been temporarily reduced due to high brake disc temperature. The function is activated automatically when the brakes have cooled. WARNING 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. The car's handling and stability characteristics will be altered if the spin control function has been disabled. DSTC Service required - the system has been disabled due to a fault. If this occurs: 1. Stop the vehicle in a safe place and turn off the engine. 2. Restart the engine. If the message remains when the engine is restarted, drive to an authorized Volvo workshop to have the system inspected. Operation 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.
