Warning

• Do not attempt to reproduce an emergency stop signal system malfunction. Doing so will result in a remarkable loss of vehicle stability which could cause an unexpected rear-end or other type of collision and a serious accident.

• To prevent an accident, verify the M-MDS data monitor using two people while the vehicle is being driven (One person drives vehicle and other operates the M-MDS).

• If there is any vehicle malfunction complaint lodged by a customer, perform malfunction diagnosis according to the troubleshooting procedure.
