ABSTRACT:
A warning device for a vehicle is capable of checking a disorder in the vehicle in a sequential order through a dialog between the device and an operator. The device first indicates conduction of a test before a starter is turned on and the operator depresses a test switch in compliance with this indication to test whether all indication units and buzzer can operate normally. After finishing this test, any disorder which may exist at various starting check points such as a hydraulic fluid level and a radiator water level is detected by an associated indication unit. After the starting check up has been completed and the starter is turned on, driving check points such as a torque converter oil temperature and a brake air pressure are constantly watched and if there occurs any disorder in such check points, the operator is informed of such disorder by operation of all of the indication units and the buzzer. The operator then operates only the indication unit associated with the check point where the disorder has occurred by manipulation of a check switch.
