Today I tested the FTM, but I am not sure it is working. I dropped the front right tire from 32 to 18 psi (the other tire is at 32 psi), drove 4 blocks at 30-35 mph. No low tire pressure warning. (I did reset the tire warning in the dash last night) Maybe the FTM is not yet activated? Or it takes longer than 4 blocks for the FTM to detect the low pressure?
