The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Mercedes-Benz GLE. 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 tire rotations, replacements, or when the warning light persists even after proper inflation. In this comprehensive guide, we’ll walk you through the process of resetting and relearning the TPMS for all generations of the Mercedes-Benz GLE.<>

Understanding TPMS in Mercedes-Benz GLE

Before diving into the reset procedures, it’s essential to understand what TPMS is and how it functions in the Mercedes-Benz GLE.<>

What is TPMS?

The Tire Pressure Monitoring System is an electronic system designed to monitor the air pressure inside pneumatic tires. It reports real-time tire pressure information to the driver of the vehicle, usually through a gauge or a low-pressure warning light.<>

Types of TPMS in Mercedes-Benz GLE

Mercedes-Benz typically uses two types of TPMS:<>

  1. Direct TPMS: Uses physical pressure sensors inside each tire to measure pressure accurately.
  2. Indirect TPMS: Uses wheel speed sensors and software to detect underinflated tires based on their rotational speed.

The Mercedes-Benz GLE primarily uses a direct TPMS system, which provides more accurate readings but may require specific reset procedures when tires are changed or rotated.<>

When to Reset TPMS in Mercedes-Benz GLE

You should reset the TPMS in your Mercedes-Benz GLE under the following circumstances:<>

  • After rotating tires
  • When replacing one or more tires
  • After inflating tires to the correct pressure
  • When the TPMS warning light remains on even after proper tire inflation
  • After replacing TPMS sensors

General TPMS Reset Procedure for Mercedes-Benz GLE

While the exact steps may vary slightly depending on the model year and generation of your Mercedes-Benz GLE, the following general procedure should work for most vehicles:<>

  1. Ensure all tires are inflated to the correct pressure as specified in your vehicle’s manual or on the driver’s side door jamb sticker.
  2. Turn on the ignition without starting the engine.
  3. Press the “Home” button on the steering wheel or center console.
  4. Using the touchpad or scroll wheel, navigate to the “Service” menu.
  5. Select “Tire Pressure” or “Tires” from the submenu.
  6. Choose “Restart Run Flat Indicator” or a similar option.
  7. Confirm the restart by selecting “Yes” when prompted.
  8. The TPMS light should blink three times and then turn off, indicating a successful reset.

TPMS Reset Procedures for Specific GLE Generations

Let’s break down the reset procedures for different generations of the Mercedes-Benz GLE:<>

First Generation GLE (2015-2019)

For the first generation GLE, also known as the W166 chassis:<>

  1. Ensure all tires are properly inflated.
  2. Turn the key to the “On” position without starting the engine.
  3. Press the steering wheel buttons to navigate to the “Service” menu on the instrument cluster display.
  4. Scroll to “Tire Pressure” and press “OK”.
  5. Select “Restart Run Flat Indicator” and confirm by pressing “OK”.
  6. The system will display “Run Flat Indicator Restarted” to confirm the reset.

Second Generation GLE (2020-Present)

For the current generation GLE, also known as the W167 chassis:<>

  1. Ensure all tires are properly inflated.
  2. Press the start button without pressing the brake pedal to turn on the electrical systems.
  3. On the steering wheel, use the touch-sensitive buttons to navigate to “Service” in the instrument cluster display.
  4. Scroll to “Tires” and select it.
  5. Choose “Restart Tire Pressure Monitor” and confirm.
  6. The system will display a confirmation message and the TPMS light should blink before turning off.

TPMS Relearn Process for Mercedes-Benz GLE

After resetting the TPMS, some Mercedes-Benz GLE models may require a relearn process to ensure the system accurately recognizes the new tire pressures or sensor positions. This is particularly important after tire rotations or replacements.<>

Automatic Relearn Process

Many newer Mercedes-Benz GLE models feature an automatic relearn process:<>

  1. After resetting the TPMS, drive the vehicle at speeds above 20 mph (32 km/h) for at least 10 minutes.
  2. The system will automatically detect and relearn the tire positions and pressures.
  3. Once complete, the TPMS light should remain off, indicating successful relearning.

Manual Relearn Process (If Required)

Some older GLE models or those with aftermarket TPMS sensors may require a manual relearn process:<>

  1. Park the vehicle and turn off the engine.
  2. Turn the key to the “On” position without starting the engine.
  3. Press and hold the TPMS reset button (usually located under the steering wheel or in the glove box) until the TPMS light blinks three times.
  4. Start with the left front tire. Use a TPMS activation tool to trigger the sensor.
  5. Wait for a horn chirp or light flash, indicating the sensor has been recognized.
  6. Repeat the process for the right front, right rear, and left rear tires in that order.
  7. Turn off the ignition after the final tire is learned.

Troubleshooting TPMS Issues in Mercedes-Benz GLE

If you encounter problems during the reset or relearn process, consider the following troubleshooting steps:<>

TPMS Light Remains On After Reset

  • Double-check that all tires are inflated to the correct pressure.
  • Ensure you’ve followed the reset procedure correctly for your specific GLE model.
  • Drive the vehicle for at least 10 minutes at speeds over 20 mph to allow for automatic relearning.
  • If the issue persists, there may be a faulty TPMS sensor that needs replacement.

Inconsistent Tire Pressure Readings

  • Check for leaks or damage to the tires.
  • Ensure the TPMS sensors are properly installed and not damaged.
  • Consider having the sensors checked for battery life, as they typically last 5-7 years.

TPMS System Failure

If you receive a “TPMS System Failure” message:<>

  • Check for any visible damage to wheels or tires.
  • Ensure there’s no electromagnetic interference from aftermarket accessories.
  • Have the vehicle’s TPMS module checked by a certified Mercedes-Benz technician.

Maintaining Your Mercedes-Benz GLE’s TPMS

To ensure your TPMS functions correctly and provides accurate readings:<>

  • Regularly check tire pressures, at least once a month and before long trips.
  • Have your TPMS sensors checked during routine maintenance.
  • When replacing tires, consider also replacing the TPMS sensors if they’re more than 5 years old.
  • Be cautious when using tire sealants, as they can damage TPMS sensors.
  • If you switch between summer and winter tires, ensure both sets have functioning TPMS sensors.

The Importance of Proper Tire Pressure

Maintaining correct tire pressure is crucial for several reasons:<>

  • Safety: Properly inflated tires provide better handling, shorter stopping distances, and reduced risk of blowouts.
  • Fuel Efficiency: Correct tire pressure can improve fuel economy by up to 3%.
  • Tire Longevity: Proper inflation helps tires wear evenly, extending their lifespan.
  • Comfort: Correctly inflated tires provide a smoother, more comfortable ride.

TPMS Regulations and Mercedes-Benz Compliance

TPMS has been mandatory in the United States since 2007 for all new passenger vehicles. Mercedes-Benz has not only complied with these regulations but has often exceeded them, providing advanced TPMS features in their vehicles, including the GLE lineup.<>

European Regulations

In the European Union, TPMS became mandatory for all new car models from November 2012 and for all new cars from November 2014. Mercedes-Benz GLE models sold in Europe comply with these regulations, often featuring more advanced TPMS systems than the minimum required.<>

Future of TPMS Technology in Mercedes-Benz Vehicles

As automotive technology advances, so does TPMS technology. Future Mercedes-Benz GLE models may incorporate:<>

  • Integration with Advanced Driver Assistance Systems (ADAS): TPMS data could be used to enhance stability control and autonomous driving features.
  • Predictive Maintenance: AI-powered systems could predict tire issues before they occur, based on driving patterns and tire wear data.
