STARTING AND DRIVING VEHICLE SKID CONTROL SYSTEM The vehicle skid control system helps provide integrated control of the systems such as an anti-lock brake system, brake assist 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. When you turn the ignition switch on, this system always turns on. SV31037 "Slip indicator light If the vehicle is going to skid during driving, the slip indicator light flashes and an alarm sounds intermittently.
