Maintaining optimal tire pressure in your Audi A5 is crucial for ensuring your safety, maximizing fuel efficiency, and enjoying peak performance on the road. The Tire Pressure Monitoring System (TPMS) in your Audi is designed to keep you informed about your tire pressure, alerting you to any deviations from the recommended levels. This guide will help you understand your Audi A5’s tire pressure display, why it matters, and how to manage it effectively.
Why Tire Pressure Matters for Your Audi A5
Driving with the correct tire pressure offers a multitude of benefits for your Audi A5. Neglecting tire pressure can lead to several issues that compromise your driving experience and vehicle longevity.
Safety First
Properly inflated tires are fundamental to your safety on the road. Underinflated tires can lead to:
- Increased risk of tire blowouts: Low pressure causes tires to flex more, generating excessive heat that can weaken the tire structure and result in sudden failure, especially at high speeds.
- Reduced braking performance: Tires with insufficient pressure deform more during braking, increasing stopping distances and compromising your ability to avoid accidents.
- Compromised handling and stability: Inadequate tire pressure diminishes steering responsiveness and cornering grip, making your Audi A5 less stable and predictable, particularly in emergency maneuvers.
Fuel Efficiency Savings
Tire pressure directly impacts your Audi A5’s fuel consumption. Underinflated tires increase rolling resistance, meaning your engine has to work harder to move the vehicle. This translates to:
- Lower miles per gallon (MPG): You’ll find yourself visiting the gas station more frequently as your fuel economy decreases.
- Increased fuel costs: Over time, the cumulative effect of driving on underinflated tires can significantly increase your fuel expenses.
Performance and Handling Optimization
For Audi A5 drivers who appreciate the vehicle’s sporty handling, tire pressure is paramount. Correctly inflated tires ensure:
- Optimal contact patch: The tire’s contact area with the road is maximized, providing the intended grip and responsiveness for precise steering and cornering.
- Enhanced driving dynamics: Your Audi A5 will feel more agile, responsive, and enjoyable to drive when the tires are properly inflated.
Tire Longevity
Maintaining correct tire pressure is an investment in the lifespan of your tires.
- Reduced wear and tear: Both underinflation and overinflation can lead to uneven tire wear patterns. Underinflation causes wear on the tire shoulders, while overinflation results in center wear. Proper inflation promotes even wear across the tire tread, extending tire life.
- Cost savings on tire replacement: By prolonging tire life, you delay the need for costly tire replacements.
Decoding Your Audi A5 Tire Pressure Display
Your Audi A5’s TPMS display is designed to be intuitive, alerting you when tire pressure deviates from the recommended levels.
Understanding the TPMS Warning Light
The most common indication of a tire pressure issue is the TPMS warning light illuminating on your dashboard. This light, often resembling a horseshoe shape with an exclamation point (!), signals that one or more of your tires are significantly underinflated. In some cases, it may also indicate overinflation or a TPMS malfunction.

Where to Find Recommended Tire Pressure
Knowing the recommended tire pressure for your Audi A5 is essential. You can typically find this information in several locations:
- Driver’s side doorjamb: A sticker on the doorjamb provides the recommended tire pressure for both normal and maximum load conditions. This is usually the most convenient and accurate source.
- Owner’s manual: Your Audi A5 owner’s manual will also list the recommended tire pressures, along with other important tire-related information.
- Fuel filler door: In some Audi A5 models, you might find a sticker with tire pressure information on the fuel filler door.
It’s crucial to adhere to the recommended tire pressures specified for your Audi A5 model, as these values are determined by the manufacturer to optimize safety, performance, and fuel efficiency.
How to Reset the Tire Pressure Monitoring System in Your Audi A5
After adjusting your tire pressure, or if the TPMS light remains on even after ensuring correct pressure, you may need to reset the system. Here’s how to reset the TPMS on your Audi A5 using the MMI (Multi Media Interface) control panel:
- Turn the ignition on: Start your Audi A5, but you don’t need to start the engine. Just turn the ignition to the “on” position.
- Access the “Car” menu: On your MMI control panel, locate and press the “car” button. This will bring up the main car settings menu on your display screen.
- Navigate to “Service & Checks”: Within the “car” menu, use the MMI controls to select “Service & Checks”. You may need to use a rotary dial or touch controls depending on your MMI version.
- Find “Tire Pressure Monitoring”: Scroll through the “Service & Checks” menu until you find and highlight “Tire Pressure Monitoring”.
- Store Current Tire Pressure: Once “Tire Pressure Monitoring” is highlighted, select the option that says “Store Current Tire Pressure.” The system will prompt you to confirm that you have checked your tires and adjusted the pressure. Confirm by selecting “Yes” or “OK”.
- Confirmation Message: A message “Tire Pressures are Being Stored” will appear on the screen, indicating that the system is resetting and learning the new tire pressure values.
- Reset Complete: Once the process is complete, the TPMS warning light should turn off (if it was illuminated due to pressure issues) and your Tire Pressure Monitoring System is reset.

If the TPMS warning light persists after resetting the system and ensuring correct tire pressure, it may indicate a sensor malfunction or another issue within the TPMS. In such cases, it’s recommended to consult with a qualified Audi service center like Fletcher Jones Audi to diagnose and resolve the problem. Regularly checking and maintaining your Audi A5’s tire pressure is a simple yet vital aspect of vehicle ownership that contributes significantly to safety, efficiency, and driving enjoyment.
