Operation Tires and wheels i If the positions of the wheels have not been changed on the vehicle, the tire inflation pressures are shown correctly after a short period. If the positions of the wheels have been switched, however, it is possible that the tire inflation pressures are temporarily shown for the wrong wheel positions. They are corrected after a few minutes of driving, and the tire inflation pressures are shown for the correct wheel positions. Potential problems associated with underinflated and overinflated tires Underinflated tire inflation pressure Underinflated tires can: cause excessive and uneven tire wear adversely affect fuel economy lead to tire failure from being overheated adversely affect handling characteristics Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Overinflated tire inflation pressure Overinflated tires can: adversely affect handling characteristics cause uneven tire wear be more prone to damage from road hazards adversely affect ride comfort increase stopping distance Warning! G G Follow recommended tire inflation pressures. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. 326
