⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secured and on a level surface before working on the tires.
•Wear gloves and safety glasses when handling tires and tools.
•Check if the tire pressure warning light is no longer illuminated after adjustments.
•Test drive the vehicle to ensure stable handling and performance.
•Re-check tire pressures after a short drive to confirm they remain at the correct levels.
•Regularly check tire pressures at least once a month.
•Rotate tires according to manufacturer recommendations to ensure even wear.
•Inspect tires for damage or wear during routine maintenance.
•Replace damaged or worn tires promptly to maintain safety and performance.
•Ensure proper inflation before long trips or heavy loads.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible decrease in vehicle handling or stability
•Visual inspection shows a tire may appear flat or under-inflated
•Increased tire wear or uneven tire pressure readings
•Warning message displayed on the vehicle's infotainment system

Diagnostic Steps

1
Check the current tire pressures using a tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify the tire pressure monitoring system (TPMS) status using the vehicle’s onboard diagnostics.
4
If applicable, check for any stored error codes related to the TPMS using an OBD-II scanner.
5
Reset the TPMS using the vehicle's settings if tire pressures are correct.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves as needed.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Compare readings to the recommended pressure found on the driver’s side door jamb.
4. Inflate tires to the recommended pressure using an air compressor if necessary.
5. Reinstall valve stem caps securely.

3. Inspect and Repair Tires

Sub-steps:
1. Examine each tire for visible damage such as cuts, punctures, or bubbles.
2. If damage is found, replace the tire or use a tire repair kit for minor punctures.
3. Check the sidewalls and tread for unusual wear patterns indicating alignment or suspension issues.

4. Reset the Tire Pressure Monitoring System (TPMS)

Sub-steps:
1. Turn the ignition key to the "On" position without starting the engine.
2. Access the vehicle settings through the infotainment system.
3. Navigate to "Vehicle Settings" > "Tires" > "Reset Tire Pressure Monitor."
4. Confirm the reset and wait for the system to recalibrate.

Tools Required:
