⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely parked before performing any tire maintenance.
•Use caution when working with compressed air and tire repair chemicals.

Symptoms

•Low tire pressure warning illuminated on the dashboard
•Tire pressure monitoring system (TPMS) alert message displayed
•Potentially uneven tire wear
•Reduced vehicle handling and stability
•Increased road noise or vibration while driving

Diagnostic Steps

1
Check the tire pressure using a digital or analog tire pressure gauge.
2
Visually inspect each tire for signs of damage or punctures.
3
Verify the recommended tire pressure specified in the owner’s manual or on the driver's door jamb.
4
Inspect the TPMS sensors for any visible damage or corrosion.
5
Look for any recent changes in driving conditions or load that may have affected tire pressure.
6
Check for temperature changes, as cold weather can lower tire pressure.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and safety glasses if necessary.

2. Inflate Tires

Tools Required: Tire pressure gauge, air compressor.
Instructions:
1. Remove the valve stem caps from each tire.
2. Using the tire pressure gauge, measure the current pressure of each tire.
3. Refer to the recommended tire pressure and inflate the tires using the air compressor until they reach the correct PSI.
4. After inflating, recheck the tire pressure to ensure it is accurate.
5. Replace the valve stem caps securely.

3. Inspect and Repair

Tools Required: Tire repair kit (if necessary).
Instructions:
1. If any tire is found to be damaged or punctured, assess the extent of the damage.
2. If the damage is repairable (e.g., small puncture), use the tire repair kit to fix the tire according to the kit instructions.
3. If the tire is beyond repair, remove it and replace it with a new tire.
4. Reinstall the tire on the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Reset TPMS

Instructions:
1. Turn on the vehicle and navigate to the settings menu on the dashboard.
2. Find the "Tire Pressure" or "TPMS" section.
3. Select the option to reset or recalibrate the TPMS system.
4. Confirm the reset and exit the menu.
