Hold down the black knob on the dashboard and turn the ignition key three times to reset it. Introduction to the light: The car maintenance light is an indicator that illuminates when the vehicle reaches the scheduled maintenance mileage within the preset maintenance cycle, prompting the need for vehicle maintenance. As driving time increases, the wear and tear on internal components of the vehicle gradually intensifies. To ensure normal operation, manufacturers have installed reminder indicator lights. Upon reaching a certain mileage, the owner should promptly replace the components. After successful replacement, it is also necessary to reset the car's maintenance light to zero. Function of the maintenance light: The purpose of these lights is to record the mileage usage of important components, much like a timer in a sprint race, serving as a reminder for both the vehicle owner and automotive maintenance personnel. However, if the owner replaces the relevant components but fails to reset the maintenance light, it generally does not affect the vehicle's performance but can cause unnecessary trouble for the next component replacement—specifically, the inability to accurately track the usage time of the new components.

I got this! First, sit in the car and turn off the engine, remember to pull the handbrake. Then locate the small mileage display button near the instrument panel (that's the Trip button), press and hold it firmly. With your other hand, turn the key to the power-on position, but don't start the engine! Now watch the instrument panel closely - the light will start blinking. Keep holding the button for about 10 seconds until the light completely goes off before releasing. Turn off the power and restart the car; if the light doesn't come back on, you've succeeded. I helped my neighbor with this procedure on their 2017 model last year - the key is holding the button long enough. Also, note that button locations may vary by model year; for the 2015 model, the button is on the left side of the steering wheel and you might need to feel around to find it.

Three simple steps to reset: Park and turn off the engine → Hold the Trip button on the dashboard → Turn the key to power on and wait for 10 seconds. I've shared this trick in the car owners' group – the key is to keep holding until all indicator lights completely go off. After completion, it's best to restart the engine to confirm. The light is just a small reminder from the onboard computer; manually resetting it won't affect other systems. However, if repeated attempts fail, you might need to visit a 4S shop for a diagnostic tool reset – they can handle it in two minutes. Remember to reset it after routine maintenance, otherwise the persistent light can be annoying.

For my 2016 Tiggo5, I always reset the light myself. After parking, just press and hold the round Trip button on the dashboard while turning the key to the position where the dashboard powers on (don't start the engine). You'll see the red oil light flashing—keep holding the button for about seven or eight seconds until the light goes off. If it fails, just repeat the process; usually, the first attempt doesn't last long enough. This method is much simpler than older models, which used to require things like pressing the accelerator.

Before operation, ensure the gear is in P position and the handbrake is engaged for safety. Specific steps: Press the ignition switch to completely turn off the engine, then locate the Trip reset button (the one with an arrow symbol) on the right side of the instrument panel. Hold down the button with your index finger, and simultaneously press the start button to power on the instrument panel (do not press the brake pedal). Wait for about 20 seconds until the reminder light turns off, then release the button. After completion, remember to start the engine to verify the effect. Here's an additional fun fact: After the maintenance light is reset, the system will automatically calculate a new cycle, and the reminder will reappear after 5,000 kilometers, so regular maintenance is the key.

Last time, the guy at the 4S store taught me a clever trick: After turning off the engine, press and hold the Trip button below the steering wheel for more than 10 seconds. With your other hand, turn the key to the ON position (just until the dashboard lights up). At this point, the light is usually on continuously, and when it suddenly turns off, it means the reset is complete. Don’t release the button during the process—if your hand strength is weak, using both hands is fine. This operation is equivalent to refreshing the car’s computer data, similar to resetting a phone to factory settings. If you notice the lights flashing inexplicably, it might be a false trigger due to unstable battery voltage, so it’s better to check the battery status before proceeding.
