First, inflate the tires. After inflating, use the main menu button on the dashboard to navigate to vehicle information and select the tire pressure reset option. Then, follow the Chinese prompt asking whether to proceed with the reset and select 'Yes'.
Don't panic when the tire pressure warning light comes on in your Mercedes-Benz GLA200 - I've handled this several times. The key is to first check the tire pressure. Mercedes' recommended pressure is usually on a small label by the driver's door frame, like 240 kPa for front tires and 250 kPa for rear tires. Use an air pump or gas station compressor to adjust all tires to standard values. Then start the engine (keep it running), navigate the left steering wheel buttons to find "Vehicle Settings," select "Tire Pressure Monitoring," and press confirm to reset. Wait a few minutes for system calibration and the light will turn off. If it stays on after reset, there might be a puncture or faulty sensor - visit a dealership immediately, especially before highway driving. Making monthly tire pressure checks a habit can prevent this issue.
When the tire pressure warning light comes on in my Mercedes-Benz GLA200, I usually do the following: First, find a safe place to pull over and check if any tire looks visibly flat or has a foreign object puncturing it. If nothing seems wrong, I use a tire pressure gauge to measure the air pressure. If the pressure is low, I head to the nearest service station to refill the tires—the standard tire pressure for this model is typically around 240 kPa. After adjusting, I start the engine and use the small knob on the dashboard to navigate to the vehicle information screen, select the tire pressure monitoring system, and press the reset button to confirm. Once reset, the system will prompt me to drive for a while to allow it to recalibrate, usually taking 5 to 10 minutes for the warning light to disappear automatically. Why does the warning light come on frequently? Temperature fluctuations or prolonged periods without checks can trigger the sensors as a safety reminder. Failing to address it promptly can damage the tires and increase fuel consumption, so I always remind myself to perform regular maintenance.
