⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is stable and properly supported before inspecting or inflating tires.
•Avoid over-inflating tires beyond the manufacturer's specified pressure.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible uneven tire wear
•Reduced handling or stability during driving
•Change in ride comfort (bumpier ride)
•Possible audible warning chimes when starting the vehicle

Diagnostic Steps

1
Verify the tire pressures using a tire pressure gauge.
2
Check the vehicle's tire pressure monitoring system (TPMS) for any fault codes using an OBD-II scanner.
3
Inspect all tires visually for visible damage, punctures, or foreign objects.
4
Confirm that the TPMS sensors are functioning correctly and have not been damaged.
5
Check the spare tire (if applicable) to ensure it is also at the correct pressure.

Solution

Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, and a tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the current tire pressure.
3. Inflate tires to the recommended pressure listed on the driver’s side door jamb sticker.
4. Recheck tire pressure after inflating to ensure it is at the correct level.
5. Replace the valve caps securely.

3. Reset TPMS (if necessary)

Sub-steps:
1. Turn the ignition to the ON position without starting the engine.
2. Press the TPMS reset button (usually located under the steering column or in the glove compartment).
3. Start the vehicle and drive for a few minutes to allow the system to recalibrate.
4. Monitor the dashboard for the tire pressure warning light to turn off.

4. Repair or Replace (if issues found)

Sub-steps:
1. If any tire is damaged or punctured, assess whether it can be repaired or needs replacement.
2. If a TPMS sensor is faulty, replace it according to the manufacturer's specifications.
3. Reinstall any components, ensuring they are secure and functioning properly.
