⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is on a flat, stable surface when checking tire pressure.
•Wear safety gloves when handling tire repairs.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible uneven tire wear
•Decreased fuel efficiency or range
•Vehicle handling issues, such as pulling to one side
•Vibration or noise while driving

Diagnostic Steps

1
Check the tire pressures of all four tires using a reliable tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify if the tire pressure monitoring system (TPMS) is functioning by checking the TPMS sensor status through the vehicle's display.
4
Check for any recent tire changes, rotations, or repairs that may have affected TPMS calibration.
5
Review the vehicle’s settings to ensure the TPMS is properly configured and reset.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

Solution

1. Tire Pressure Adjustment

Remove the valve cap from each tire.
Inflate each tire to the recommended pressure (usually found on the driver’s side door jamb).
Recheck the pressures with a gauge to ensure accuracy.
Replace the valve caps securely.

2. Tire Inspection and Repair

Inspect each tire for punctures or damage.
- If a puncture is found, assess if it’s repairable or if the tire needs replacement.
- Use a tire repair kit or take the tire to a professional service if necessary.
Check the tread depth; replace tires if tread is below the minimum safety requirements.
Rotate or align the tires if uneven wear is apparent.

3. TPMS Reset

Navigate to the vehicle's touchscreen settings.
Select "Service" and then "TPMS."
Choose the option to reset or recalibrate the TPMS system.
Drive the vehicle for a short period to allow the system to re-evaluate tire pressures.
