In this case, immediately stop your vehicle at a safe place. "VSC TRAC" warning light This light warns that there is a problem somewhere in the following. If the system continues to operate, the buzzer sound changes from intermittent to continuous. (The continuous buzzer sounds for about 3 seconds.)

However, as normal braking operates when being applied, there is no problem to continue your driving.
