bility of thevehicle. If thedrive wheels startto
spin, ASR brakes individualdrive wheels and lim‐
its theengine torque. ASR thus significantly
assists youwhen pullingawayand accelerating,
especiallyonwet or slippery roads.
If traction on theroad surface is notsufficient,
evenASR will notallow youtopull away without
difficulty.The typeoftires and total weight of the
vehicle as well as thegradient of theroad also
playacrucial role.
