⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is stable and secure before checking or inflating tires.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Decreased handling and stability during driving
•Tire(s) visibly low on air
•Increased tire wear or uneven tread patterns
•Possible noise or vibration while driving

Diagnostic Steps

1
Inspect each tire visually for signs of deflation, damage, or foreign objects.
2
Use a tire pressure gauge to measure the air pressure in each tire.
3
Check the vehicle's tire pressure monitoring system (TPMS) for any stored error codes using an OBD-II scanner.
4
Inspect the TPMS sensors on each wheel for damage or corrosion.
5
Verify the recommended tire pressure from the owner’s manual or the sticker located on the driver’s door jamb.

Solution

Diagnostic Steps

1
Inspect each tire visually for signs of deflation, damage, or foreign objects.
2
Use a tire pressure gauge to measure the air pressure in each tire.
3
Check the vehicle's tire pressure monitoring system (TPMS) for any stored error codes using an OBD-II scanner.
4

5
Verify the recommended tire pressure from the owner’s manual or the sticker located on the driver’s door jamb.

Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface and the tires are cool for accurate pressure readings.

2. Inflate Tires

Remove the valve stem caps from each tire.
Use the tire pressure gauge to check the current pressure of each tire.
Inflate each tire to the recommended pressure as specified in the owner’s manual or on the door jamb sticker using an air compressor.
Recheck the pressure with the gauge to ensure it is at the correct level.
Replace the valve stem caps securely.

3. Inspect and Reset TPMS

If the tires were inflated but the warning light remains, check the TPMS sensors for any visible damage or corrosion.
If needed, replace any faulty TPMS sensors.
Use the OBD-II scanner to reset the TPMS warning light after ensuring all tires are at the correct pressure.
