DIAGNOSIS

1. Inflate all of the tires to the recommended pressure shown in the doorjamb. Use the recommended tire pressure gauge to make sure the pressures are accurate.
2. Drive the vehicle until you see the pressure change in the multi-information display (MID).
3. Check the pressures of all of the tires in the MID. Are all of the tire pressures shown in the MID within 3 psi of what you set them at?
   • Yes – You are finished.
     NOTE: This is not a warrantable repair if the low tire pressure indicator goes off with proper air pressure.
   • No – Go to REPAIR PROCEDURE to replace any sensor that is not within this specification.
