2-4. Using other driving systems Driving assist systems To help enhance driving safety and performance, the following systems operate automatically in response to various driving situations. Be aware, however, that these systems are supplementary and should not be relied upon too heavily when operating the vehicle. n ABS (Anti-lock Brake System) Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slippery road surface. n Brake assist Generates an increased level of braking force after the brake pedal is depressed when the system detects a panic stop situation. n VSC (Vehicle Stability Control) Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces. n TRAC (Traction Control) Helps to maintain drive power and prevent the drive wheels from spinning when starting the vehicle or accelerating on slippery roads. n Hill-start assist control Helps to reduce the vehicle's rolling backward distance when starting on an incline or slippery slope. n EPS (Electric Power Steering) Employs an electric motor to reduce the amount of effort needed to turn the steering wheel. n VDIM (Vehicle Dynamics Integrated Management) Provides integrated control of the ABS, brake assist, VSC, TRAC, and hillstart assist control systems. Helps to maintain vehicle stability when swerving on slippery road surfaces by controlling the brakes and engine output. When switched to SPORT driving mode, the control characteristics of the VDIM system are altered. n Active rear wing →P. 171 166
