What does the DEF warning light in Jiangling vehicles mean?

[DamianMarie]

Jiangling DEF warning light refers to the indicator light for the vehicle's auxiliary water tank. When this light is on, it indicates that the auxiliary water tank is low on water, and water needs to be added immediately to resolve the issue. The reasons for this warning light to illuminate are: 1. Engine temperature is too high, triggering an alarm. 2. The water temperature sensor is damaged. 3. Lack of antifreeze. Types of indicator lights: 1. Oil pressure indicator: This light is used to display the oil pressure condition inside the engine. 2. Water temperature indicator: Mainly displays the temperature of the coolant in the engine. 3. Handbrake indicator: This light automatically turns on when the handbrake is engaged. 4. Battery indicator: This light also illuminates during vehicle self-check and turns off after startup. If it remains on after startup, it indicates that the battery needs replacement. 5. ABS indicator: If the ABS light does not flash when starting the engine or remains on after startup, it indicates an ABS malfunction.
