Diagnostic Steps

1
Check the tire pressure using a reliable tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or sidewall bulges.
3
Look for any visible leaks around the valve stems or tire beads.
4
Verify the recommended tire pressure values in the owner's manual or on the door jamb sticker.
5

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and valve stem tool.
Ensure the vehicle is parked on a level surface and the tires are cool for accurate pressure readings.

2. Check and Adjust Tire Pressure

Remove Valve Stem Caps: Carefully unscrew the caps from each tire’s valve stems.
Measure Tire Pressure: Press the tire pressure gauge onto each valve stem to get an accurate reading.
Inflate Tires as Needed: If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
- Note: Follow the recommended PSI values indicated on the door jamb sticker or in the owner’s manual.
Recheck Pressure: After inflating, measure the pressure again to ensure it meets specifications.

3. Inspect Tires for Damage

Visual Inspection: Look for any visible damage, such as cuts, punctures, or irregular wear on the tire surface.
Check for Leaks: Apply a soap-water solution to the valve stems and tire beads; look for bubbles indicating a leak.
Replace or Repair: If any damage or leaks are found, either repair the tire or replace it as necessary.

4. Reset TPMS

Access TPMS Menu: Using the touchscreen, go to the settings menu and locate the tire pressure monitoring system.
Initiate Reset: Follow the prompts to reset the TPMS after correcting the tire pressures.
Confirm Reset: Wait for the system to recalibrate and ensure the warning light is no longer illuminated.
