What Causes the Triangle Exclamation Mark on the Reverse Radar?

[EvelynLynn]

Common reasons for the triangle exclamation mark warning light on the reverse radar include: malfunction of the automatic headlights, low battery in the remote key requiring replacement, or a fault in the vehicle's reverse radar system. Other possible causes are as follows: 1. Engine: The engine system's exhaust emission system is substandard, or the engine control unit's memory contains fault codes. 2. Operational faults: Malfunctions in the automatic transmission or dual-clutch transmission operation. Doors not properly closed or insufficient windshield washer fluid may also trigger the warning light. 3. Other electrical components: Issues with other electrical parts may cause multiple indicator lights to illuminate simultaneously.
