To reset the tire pressure monitoring system (TPMS) on a 2019 Mercedes-Benz C-Class, follow these detailed steps:

 
Step 1: Ensure Proper Tire Inflation
 

• Before starting the reset process, ensure all tires are inflated to the recommended pressure levels specified in the owner's manual or the sticker located on the driver's side door jamb.
• Start with a cold engine and tires that have not been driven on recently to get the most accurate pressure readings.

 
Step 2: Start the Vehicle
 

• Insert the key and turn it to the ignition position, or if you have a push-start button, press it without pressing the brake pedal to turn on the electrical systems without starting the engine.

 
Step 3: Access the Instrument Cluster
 

• Use the left side steering wheel-mounted controls to navigate the instrument cluster.
• Look for the "Home" button or use the directional pads to find the "Service" menu in the display.

 
Step 4: Use the Control Buttons
 

• Press the "Home" button or scroll using the navigation controls on the steering wheel until you see the “Service” option on the screen.
• Select "Service" by pressing the confirm button or OK button on your steering wheel.

 
Step 5: Select the Tire Pressure Menu
 

• Within the "Service" menu, use the scrolling and selection buttons to navigate to the “Tire Pressure” submenu.

 
Step 6: Reset Tire Pressure
 

• When in the "Tire Pressure" submenu, the option to reset or initialize the tire pressure monitoring system should be available. Select this option by pressing the confirm or OK button.
• The system will ask for confirmation to reset, select "Yes" or "Reset" to confirm your decision.

 
Step 7: Drive the Vehicle
 

• To complete the TPMS reset process, it may be necessary to drive the vehicle for a short distance (typically a few miles) at a steady speed above 20mph (about 32 km/h).
• This action helps the system to re-learn the new tire pressure settings and clear any warnings.

 
Step 8: Verify TPMS Light Reset
 

• After driving, park the vehicle and turn off the ignition.
• Check the instrument cluster for any remaining tire pressure warnings. If done correctly, the TPMS light should no longer appear, indicating that the reset was successful.

Following these steps should successfully reset the TPMS on your 2019 Mercedes-Benz C-Class, ensuring accurate tire pressure monitoring.
