The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Mercedes-Benz GLA. This system alerts drivers when tire pressure is low, helping to prevent accidents and improve fuel efficiency. However, there are times when you need to reset or relearn the TPMS, such as after rotating tires or replacing sensors. This comprehensive guide will walk you through the process for all generations of the Mercedes-Benz GLA.

Understanding TPMS in Mercedes-Benz GLA

Before diving into the reset procedures, it’s essential to understand how the TPMS works in Mercedes-Benz GLA vehicles. The system uses sensors in each tire to monitor pressure and temperature. When a significant change is detected, it alerts the driver through a warning light on the dashboard[1].

Types of TPMS in Mercedes-Benz GLA

Mercedes-Benz GLA models typically use one of two types of TPMS:

• Direct TPMS: Uses physical sensors in each tire
• Indirect TPMS: Uses the ABS system to detect changes in tire rotation speeds

Knowing which system your GLA uses is crucial for proper reset and relearn procedures.

When to Reset or Relearn TPMS

You should reset or relearn your Mercedes-Benz GLA’s TPMS in the following situations:

• After rotating tires
• When replacing one or more tires
• After installing new TPMS sensors
• When the TPMS warning light remains on after properly inflating tires
• Seasonal tire changes (e.g., switching to winter tires)

Resetting TPMS in First Generation Mercedes-Benz GLA (2013-2019)

The first generation GLA uses a direct TPMS system. Here’s how to reset it:

1. Ensure all tires are properly inflated to the recommended pressure
2. Turn the ignition to the “ON” position without starting the engine
3. Press the “Menu” button on the steering wheel
4. Navigate to “Service” in the instrument cluster display
5. Select “Tire Pressure”
6. Choose “Restart Run Flat Indicator”
7. Press “OK” to confirm
8. The message “Run Flat Indicator Restarted” will appear
9. Start the engine and drive for at least 20 minutes at speeds above 20 mph to complete the relearn process[2]

Resetting TPMS in Second Generation Mercedes-Benz GLA (2020-Present)

The second generation GLA uses an advanced direct TPMS system. Follow these steps to reset it:

1. Ensure all tires are properly inflated
2. Turn on the vehicle without starting the engine
3. Press the home button on the steering wheel
4. Use the touch-sensitive buttons to navigate to “Service” in the instrument cluster
5. Select “Tire Pressure”
6. Choose “Restart Run Flat Indicator”
7. Confirm by pressing “OK”
8. The system will display “Run Flat Indicator Active, Restart OK”
9. Start the engine and drive for about 10 minutes at speeds over 30 mph to complete the relearn process[3]

Using MBUX System for TPMS Reset (2020+ Models)

For newer GLA models equipped with the MBUX infotainment system, you can also use the touchscreen to reset TPMS:

1. Tap the home icon on the touchscreen
2. Select “Vehicle”
3. Choose “Tire Pressure Monitor”
4. Tap “Restart Run Flat Indicator”
5. Confirm the action when prompted
6. Drive the vehicle as instructed to complete the relearn process

Troubleshooting TPMS Reset Issues

If you encounter problems during the reset process, consider the following:

• Ensure all tires are properly inflated to the correct pressure
• Check for any visible damage to tire sensors
• Verify that you’re following the correct procedure for your specific GLA model year
• If issues persist, consult your owner’s manual or contact a Mercedes-Benz dealership

Importance of Proper Tire Pressure

Maintaining correct tire pressure is crucial for several reasons:

• Improved fuel efficiency
• Enhanced handling and safety
• Extended tire life
• Reduced risk of blowouts

The TPMS helps ensure your tires are always at the optimal pressure, but it’s still important to manually check tire pressure regularly.

TPMS Sensor Replacement

TPMS sensors have a limited lifespan, typically 5-10 years, due to their internal battery. If you need to replace TPMS sensors:

1. Purchase compatible sensors for your Mercedes-Benz GLA model
2. Have them professionally installed at a Mercedes-Benz dealership or certified tire shop
3. Perform the TPMS reset and relearn procedure after installation

Winter Tires and TPMS

When switching to winter tires, consider the following:

• If your winter tires have their own TPMS sensors, you’ll need to reset and relearn the system after installation
• For winter tires without sensors, some Mercedes-Benz models allow you to temporarily disable TPMS warnings
• Always consult your owner’s manual for specific instructions regarding winter tire use and TPMS

Legal Requirements and TPMS

It’s important to note that TPMS is a legally required safety feature in many countries:

• In the United States, all vehicles manufactured after September 1, 2007, must have TPMS
• European Union regulations mandated TPMS for all new passenger vehicles from November 1, 2014
• Disabling or tampering with TPMS may be illegal and could affect your vehicle’s warranty

Advanced TPMS Features in Newer GLA Models

Recent Mercedes-Benz GLA models offer advanced TPMS features:

• Individual tire pressure and temperature readings
• Automatic recognition of tire changes
• Integration with navigation systems for altitude-based pressure adjustments

These features may require specific reset procedures, so always refer to your owner’s manual for the most accurate information.

Maintaining Your Mercedes-Benz GLA’s TPMS

To ensure your TPMS functions correctly:

1. Regularly check tire pressure, including the spare tire
2. Have TPMS sensors checked during routine maintenance
3. Keep the vehicle’s software up to date, as some updates may improve TPMS functionality
4. Address any TPMS warnings promptly
5. Use only Mercedes-Benz approved tires and TPMS sensors for replacements

Common TPMS Warning Messages and Their Meanings

Understanding TPMS warning messages can help you address issues quickly:

TPMS and Vehicle Safety Systems

The TPMS in Mercedes-Benz GLA models works in conjunction with other safety systems:

• Anti-lock Braking System (ABS)
• Electronic Stability Program (ESP)
• Adaptive Cruise Control

Proper TPMS function ensures these systems have accurate tire information for optimal performance.

Future of TPMS Technology in Mercedes-Benz Vehicles

Mercedes-Benz continues to innovate in TPMS technology:

• Integration with autonomous driving systems
• Predictive maintenance alerts
• Enhanced tire health monitoring

These advancements may introduce new reset and relearn procedures in future GLA models.

Conclusion

Properly maintaining and resetting your Mercedes-Benz GLA’s TPMS is crucial for safety, performance, and compliance with legal requirements. By following the procedures outlined in this guide and staying informed about your specific model’s requirements, you can ensure your TPMS functions correctly, providing peace of mind on every journey.

Remember, while these instructions are comprehensive, always consult your vehicle’s owner’s manual or a certified Mercedes-Benz technician for model-specific guidance. Regular maintenance and prompt attention to TPMS warnings will help keep your GLA running smoothly and safely for years to come.
