STARTING AND DRIVING VEHICLE SKID CONTROL SYSTEM The vehicle skid control system helps provide comprehensive control of the systems such as an anti-lock brake system, traction control, engine control, etc. This system automatically controls the output of the brakes or engine to help prevent the vehicle from skidding when cornering on a slippery road surface or abrupt steering wheel operation occurs. You may hear a sound in the engine compartment for a few seconds when the engine is started or just after the vehicle is started. This means that the vehicle skid control is in the self-check mode and does not indicate a malfunction. 31G021 31G013 You can turn off the vehicle skid control system by pushing the "VSC OFF" switch.
