The DEF warning light refers to the indicator light for the vehicle's auxiliary water tank. Here is some related information about warning lights coming on: 1. The car won't start: This could be due to a fuel pump or ignition component failure. Call for assistance immediately. 2. Warning light is on: But no abnormalities in driving are observed. This might just be a sensor malfunction. You can continue driving temporarily, but it's best to drive at low to medium speeds. 3. Engine warning light is on: The vehicle can still be driven, but symptoms like severe shaking or lack of acceleration power appear. In this case, you should stop the vehicle and call for roadside assistance.
