Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor (if needed), jack, jack stands, and lug wrench.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

Check Current Pressure: Use a tire pressure gauge to measure the pressure in each tire.
Compare to Specifications: Refer to the owner’s manual or the door jamb sticker for the recommended tire pressure.
Inflate as Necessary: If any tire is below the recommended pressure, use an air compressor to inflate the tire to the specified PSI.
- Tip: Inflate slowly and re-check pressure frequently.

3. Inspect and Repair

Visual Inspection: Look for punctures, bulges, or any visible damage on the tire surfaces.
Repair or Replace: If any damage is found, either repair the tire with a patch or plug, or replace it if the damage is severe.
- Note: Punctures in the tread area can often be repaired, but sidewall damage typically requires tire replacement.

4. Reset TPMS

Reset the System: After inflating the tires and ensuring they are in good condition, reset the tire pressure monitoring system using the vehicle’s touchscreen interface.
- Navigate to Settings > Service > Tire Pressure Monitoring and follow the prompts to reset.
