VDC Function
- In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected from steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under steering / over steering) is determined from information from G-sensor, wheel sensor, etc., and this information is used to improve vehicle stability by controlling the braking and engine power to all four wheels.
- SLIP indicator lamp flashes to inform the driver of VDC operation.
- During VDC operation, body and brake pedal lightly vibrate and mechanical noises may be heard. This is normal.
- ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when vehicle is subject to strong shaking or large vibration, such as when vehicle is on a turn table, a ship or a steep slope such as bank while engine is running. In this case, restart engine on a normal road, and if ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off, there is no problem.
