This comprehensive guide will walk you through the process of resetting and relearning the TPMS for all generations of the Mercedes-Benz CLA.<>
Understanding TPMS in Mercedes-Benz CLA
Before diving into the reset procedures, it’s essential to understand what TPMS is and how it functions in Mercedes-Benz vehicles.<>
What is TPMS?
TPMS is an electronic system designed to monitor the air pressure inside pneumatic tires. It reports real-time tire pressure information to the driver, usually through a gauge or a warning light in the dashboard.<>
Types of TPMS in Mercedes-Benz CLA
Mercedes-Benz typically uses two types of TPMS:<>
- Direct TPMS: Uses physical pressure sensors in each tire
- Indirect TPMS: Uses wheel speed sensors and software algorithms to detect underinflation
The CLA models generally use the indirect TPMS, which is why a reset and relearn procedure is necessary after tire maintenance.<>
Importance of Proper Tire Pressure
Maintaining correct tire pressure is crucial for several reasons:<>
- Safety: Properly inflated tires provide better handling and reduce the risk of blowouts
- Fuel Efficiency: Correct tire pressure can improve fuel economy by up to 3%
- Tire Longevity: Properly inflated tires wear more evenly, extending their lifespan
- Comfort: Correct tire pressure ensures a smoother ride
When to Reset TPMS in Mercedes-Benz CLA
You should reset the TPMS in your Mercedes-Benz CLA in the following situations:<>
- After rotating tires
- After replacing one or more tires
- When the TPMS warning light remains on after inflating tires to the correct pressure
- After any tire-related maintenance
Preparing for TPMS Reset
Before resetting the TPMS, ensure the following:<>
- All tires are inflated to the correct pressure (check the driver’s side door jamb or owner’s manual for specifications)
- The vehicle has been stationary for at least 20 minutes
- You have the necessary tools (usually just the vehicle’s built-in controls)
TPMS Reset Procedure for First Generation Mercedes-Benz CLA (2013-2019)
For the first generation CLA, follow these steps:<>
- Turn the ignition to the “ON” position without starting the engine
- Press the “Home” button on the steering wheel
- Use the scroll wheel to navigate to “Service” in the instrument cluster display
- Press “OK” to enter the Service menu
- Scroll down to “Tire Pressure” and press “OK”
- Select “Restart Run Flat Indicator” and press “OK”
- Confirm by selecting “Yes” and pressing “OK”
- The system will display “Run Flat Indicator Restarted”
TPMS Reset Procedure for Second Generation Mercedes-Benz CLA (2020-Present)
For the latest generation CLA, the process is slightly different:<>
- Ensure the vehicle is in “Park” and turn the ignition on
- Press the home button on the steering wheel
- Use the touch-sensitive button on the steering wheel to scroll right to “Service”
- Press and hold the touch-sensitive button for about 3 seconds
- Scroll down to “Tires” and select it
- Choose “Restart Tire Pressure Monitor”
- Confirm by selecting “Yes”
- The system will display “Tire Pressure Monitor Restarted”
TPMS Relearn Process
After resetting the TPMS, the system needs to relearn the new tire pressures. This process is automatic in Mercedes-Benz vehicles:<>
- Drive the vehicle at speeds above 20 mph (32 km/h) for about 10 minutes
- The system will automatically calibrate and learn the new tire pressures
- If the TPMS light doesn’t turn off after this process, repeat the reset procedure or consult a professional
Troubleshooting TPMS Issues
If you encounter problems with your TPMS, consider the following:<>
- Ensure all tires are properly inflated
- Check for any visible damage to tires or wheels
- Verify that you’re using Mercedes-Benz approved tires
- If issues persist, consult a Mercedes-Benz dealership or certified mechanic
Maintaining Your Mercedes-Benz CLA’s TPMS
To keep your TPMS functioning correctly:<>
- Regularly check tire pressure (at least once a month)
- Rotate tires according to the manufacturer’s schedule
- Replace TPMS sensors when replacing tires (typically every 6-8 years)
- Have the system checked during routine maintenance
The Importance of Professional Service
While resetting the TPMS is a task many car owners can handle, there are times when professional service is necessary:<>
- If the TPMS light continues to illuminate after reset and relearn procedures
- When replacing TPMS sensors
- If you suspect a malfunction in the TPMS system
- During complex tire or wheel replacements
Mercedes-Benz certified technicians have the expertise and specialized equipment to diagnose and resolve complex TPMS issues.<>
TPMS and Vehicle Safety
The TPMS is more than just a convenience feature; it’s a critical safety system. Properly functioning TPMS can:<>
- Prevent accidents caused by underinflated tires
- Improve vehicle handling and stability
- Reduce the risk of tire blowouts
