⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely parked and stable before performing any tire work.
•Avoid working on tires in confined spaces where ventilation is limited.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Tire pressure monitoring system (TPMS) alert displayed on the screen
•Possible visible deflation in one or more tires
•Vehicle handling feels unstable or different during driving
•Increased tire wear noted during inspection

Diagnostic Steps

1
Check the tire pressure of all four tires using a reliable tire pressure gauge.
2
Inspect the tires visually for any signs of punctures, damage, or sidewall bulges.
3
Verify the temperature of the tires; cold temperatures can affect tire pressure readings.
4
Reset the TPMS using the vehicle settings menu to see if the warning persists.
5
Inspect the TPMS sensors for possible malfunction or damage.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure vehicle is parked on a flat surface and secure the vehicle with wheel chocks.
Tools Required: Tire pressure gauge, air compressor, TPMS reset tool if needed.

2. Check and Inflate Tires

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Compare the readings to the recommended tire pressure (found on the driver’s door jamb sticker).
4. If any tire is below the recommended pressure, inflate it to the proper level using an air compressor.
5. Replace the valve caps securely after inflating.

3. Inspect for Damage

Sub-steps:
1. Examine each tire for visible punctures, cracks, or abnormal wear.
2. Check the sidewalls for any bulging or cuts.
3. If damage is found, consider replacing the affected tire.

4. Reset TPMS

Sub-steps:
1. Access the vehicle's settings menu on the touchscreen.
2. Navigate to the "Service" section.
3. Select "Reset TPMS" and follow on-screen prompts to complete the reset.

5. Test Drive and Monitor

Sub-steps:
1. Drive the vehicle for a short distance to allow the TPMS to recalibrate.
2. Monitor the dashboard for any reoccurrence of the low tire pressure warning.
