Estimated Time

30 minutes to 1 hour

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a flat surface before checking tire pressure.
•Wear safety glasses when inspecting tires for damage.

Symptoms

•Warning message displayed on the dashboard indicating low tire pressure
•Decreased handling and stability while driving
•Increased road noise from tires
•Visible flattening or bulging of one or more tires
•Possible loss of traction, especially in wet conditions

Diagnostic Steps

1
Use a tire pressure gauge to measure the pressure in each tire.
2
Check the tire pressure specifications in the owner’s manual or on the driver’s side door jamb.
3
Inspect the tires for any visible damage, such as cuts, punctures, or bulges.
4
Look for any signs of a slow leak, such as uneven wear or a hissing sound when the tire is inflated.
5
Verify that the tire pressure monitoring system (TPMS) is functioning correctly by checking for any error codes using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and tire sealant if needed.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Inflate Tires

Sub-step 1: Remove the valve cap from each tire.
Sub-step 2: Use the tire pressure gauge to measure the tire pressure.
Sub-step 3: Compare the measured pressure with the recommended pressure (found in the owner’s manual or on the door jamb).
Sub-step 4: If the pressure is below the recommended level, use an air compressor to inflate the tire to the correct pressure.
Sub-step 5: Replace the valve cap securely after inflating.

3. Inspect for Damage

Sub-step 1: Visually inspect each tire for any signs of punctures, cuts, or abnormal wear.
Sub-step 2: If any damage is found, consider using tire sealant for minor punctures or take the vehicle to a tire shop for professional assessment and repair.
Sub-step 3: Check the sidewalls for bulges or cracks that may indicate a need for tire replacement.

4. Reset TPMS (if applicable)

Sub-step 1: Use the vehicle’s touchscreen to navigate to the tire pressure monitor settings.
Sub-step 2: Follow the prompts to reset the TPMS after adjusting the tire pressures.
