Diagnosis Procedure

INFOID:0000000010501248

1.

FORWARD EMERGENCY BRAKING DIAGNOSIS

• The system will be cancelled automatically with a beep sound and FEB warning lamp on the combination

meter will illuminate, when the system will not operate properly.

• When the FEB warning lamp continues to illuminate even if the FEB system is turned on after the engine

restarts, perform the trouble-diagnosis.
