⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a stable surface before lifting.
•Allow tires to cool before measuring pressure to avoid false readings.

Symptoms

•Check tire pressure warning light illuminated on the dashboard
•Noticeable decrease in tire pressure readings on the display
•Uneven tire wear visible on the tread pattern
•Vibration or pulling to one side while driving
•Reduced handling performance or stability

Diagnostic Steps

1
Inspect each tire visually for any visible damage, punctures, or foreign objects.
2
Check the tire valve stems for leaks or damage.
3
Use a tire pressure gauge to measure the actual tire pressure compared to the recommended pressure.
4
Inspect the wheels for any cracks or bends that could cause air loss.
5
Perform a soapy water test around the tire beads and valve stems to identify leaks.
6
Scan the vehicle’s system for any tire pressure monitoring system (TPMS) error codes.

Solution

Solution

1. Preparation

Tools Required: Tire pressure gauge, soapy water solution, air compressor, jack, jack stands, tire repair kit (if needed).
Ensure the vehicle is parked on a flat, stable surface and the engine is off.

2. Inspect and Repair Tire Damage

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the tire if damage is detected that requires repair.
- Use the tire repair kit to address any punctures, or replace the tire if there is significant damage.
- If no visible damage is found, proceed to the next step.

3. Check and Repair Valve Stems

Sub-steps:
- Inspect the valve stems for cracks or damage.
- Replace any damaged valve stem with a new one.
- Tighten the valve core if it’s loose.

4. Reinflate Tires

Sub-steps:
- Use an air compressor to inflate each tire to the manufacturer-recommended pressure (found on the driver’s side door jamb).
- Monitor the tire pressure gauge while inflating to ensure accuracy.

5. Reset Tire Pressure Monitoring System (TPMS)

Sub-steps:
- After ensuring all tires are properly inflated, reset the TPMS by accessing the vehicle settings via the touchscreen.
- Select the option to recalibrate or reset the tire pressure monitoring system.
