Estimated Time

30 minutes to 1 hour

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a stable surface when checking or inflating tires.
•Avoid driving on under-inflated tires to prevent further damage or safety issues.

Symptoms

•Warning message displayed on the dashboard
•Tire pressure monitoring system (TPMS) light illuminated
•Decreased handling stability or increased tire noise
•Uneven tire wear patterns
•Potential decrease in vehicle range or efficiency

Diagnostic Steps

1
Check the tire pressure of all tires using a tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify that the tires are properly seated on the rims and not leaking air.
4
Check the ambient temperature, as tire pressure can drop in colder conditions.
5
If applicable, confirm that the TPMS sensors are functioning properly by using a TPMS tool.

Solution

Solution

1. Preparation

Gather all necessary tools: tire pressure gauge, air compressor, and possibly a jack and jack stands if a tire needs to be removed.
Ensure the vehicle is on a flat surface.

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 in each tire.
3. Refer to the vehicle's door jamb sticker for the recommended tire pressure values.
4. If pressure is below the recommended value, use an air compressor to inflate the tire to the correct level.
5. Replace the valve caps securely after inflating.

3. Inspect for Damage

Sub-steps:
1. Visually examine each tire for any bulges, cuts, or punctures.
2. If any damage is detected, consider replacing the tire or consulting a tire specialist for repair.

4. Reset the TPMS (if necessary)

Sub-steps:
1. Access the vehicle's settings through the touchscreen.
2. Navigate to the "Service" section and select "Reset Tire Pressure Monitoring System."
3. Confirm the reset and wait for the system to recalibrate.
