Press button j or k repeatedly until you see the current inflation pressures for each tire appear in the multifunction display or the following message appears in the multifunction display: Tire pressure displayed only after driving a few mins. Warning! G i If you are transporting a deflated tire in the vehicle, do not activate the tire pressure monitoring system until the deflated tire is no longer in the vehicle you have inflated the tire to the correct pressure Press the reset button on the instrument cluster ( page 24). The following message will appear in the multifunction display: Check current tire pres.? Follow recommended tire inflation pressures. Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes, etc. Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the pillar in the driver's door opening). Overloading the tires can overheat them, possibly causing a blowout. 324
