The tire pressure values stored at the last restart will continue to be monitored. Maximum tire pressures G Warning Never exceed the maximum tire inflation pressure. 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. 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. Two instruction labels on your vehicle show the maximum possible load. (1) The Tire and Loading Information placard on the B-pillar on the driver's side. the Tire and Loading Information placard shows the maximum possible number of occupants and the maximum possible vehicle load.
