⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a level surface and the tires are cold to get an accurate reading.
•Ensure the vehicle is properly supported on jack stands when lifting to avoid accidents.
•Allow tires to cool before measuring pressure for accurate readings.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Possible uneven wear on tire tread
•Decreased fuel efficiency or range
•Vehicle handling feels unstable or pulls to one side
•Visual inspection shows visibly deflated tire(s)

Diagnostic Steps

1
Check the tire pressure using a tire pressure gauge for all four tires.
2
Inspect each tire visually for any signs of punctures, sidewall damage, or foreign objects lodged in the tread.
3
Verify the recommended tire pressure for the vehicle, typically located on the driver’s door jamb.
4
Check the tire pressure monitoring system (TPMS) settings using the vehicle’s display to see if there are any alerts or codes.
5
Examine the valve stems for signs of air leakage or damage.

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, valve core tool (if needed)
Safety Warnings: Ensure the vehicle is parked on a level surface and the tires are cold to get an accurate reading.

2. Inflate Tires

Remove the valve cap from each tire.
Use the tire pressure gauge to measure the current tire pressure of each tire.
If the tire pressure is below the recommended level, attach the air compressor nozzle to the valve stem.
Inflate the tire to the recommended pressure as specified in the owner’s manual or on the driver’s door jamb.
Recheck the tire pressure with the gauge to confirm it is at the correct level.

3. Repair or Replace Tires (if necessary)

If any tire has visible damage, assess whether it can be repaired or needs replacement.
For minor punctures, use a tire repair kit to seal the hole following the kit’s instructions.
If the tire is beyond repair, remove the damaged tire using a jack and a lug wrench.
- Sub-steps:
- Jack up the vehicle and secure it with jack stands.
- Loosen and remove the lug nuts, then take off the tire.
- Install a new tire, hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to the manufacturer's specifications.

4. Reset TPMS

After adjusting tire pressures, reset the TPMS through the vehicle’s settings menu.
Follow the on-screen instructions to complete the reset process.
