Operation Tires and wheels Warning! G Activating the tire inflation pressure monitor You must activate the tire inflation pressure monitor in the following cases: If you have changed the tire pressure If you have replaced the wheels or tires If you have installed new wheels or tires Make sure the tire pressure is correctly set. Press button è or ÿ on the multifunction steering wheel repeatedly until the standard display menu appears in the multifunction display ( page 129). 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. Press button j or k repeatedly until you see the current inflation pressures for each tire appear in the display or the following message appears in the display TIRE PRES. DISPLAY AFTER DRIVING A FEW MINS. REACTIVATE USING R-BUTTON i If transporting a deflated road wheel or additional wheel sensors in the vehicle, the tire inflation pressure monitor should not be reactivated until the deflated wheel or additional wheel sensors have been removed from the vehicle. Otherwise, the deflated wheel or additional sensors could cause the tire inflation pressure monitor system to malfunction. 274
