Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, tire repair kit (if needed), and a jack.
Ensure the vehicle is parked on a flat surface and turn off the engine.

2. Tire Pressure Adjustment

Check and Inflate Tires:
1. Remove the valve stem caps from all tires.
2. Use the tire pressure gauge to measure the current pressure in each tire.
3. Compare the measured pressure to the recommended pressure found on the driver’s door jamb sticker.
4. If the pressure is low, use an air compressor to inflate the tire to the recommended level.
5. Replace the valve stem caps securely after inflation.

3. Inspect and Repair

Visual Inspection:
1. Look for any visible damage on each tire.
2. If any punctures or leaks are found, repair them using a tire repair kit or replace the tire if necessary.
3. Inspect the valve stems for leaks; replace if damaged.

4. Reset TPMS (if applicable)

System Reset:
1. Turn on the ignition without starting the engine.
2. Navigate to the vehicle settings on the dashboard display.
3. Select the option to reset the tire pressure monitoring system.
4. Confirm the reset and turn off the ignition.
