These items are not yet programmed for your car so do not trust the manufacturer. The tire shops told me to go to a retraining class and I've been doing this for an hour and still say the system will service the tire with 3 low pressure tires soon. Purchase at your own risk. I can't use the Relearn tool because my car doesn't have the luxury of driving around and praying for the message light and annoying blinking TPMS light to go out. What a waste.
