Tire pressure "Technical Data" section to avoid damage to the vehicle or the wheels. ROnly 483 Tire pressure Tire pressure specifications G 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. 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. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. use snow chains when driving on an area completely covered by snow. Do not exceed the maximum permissible speed of 30 mph (50 km/h). Remove the snow chains as soon as possible when you are no longer driving on snow-covered roads. RLocal regulations may restrict the use of snow chains. Applicable regulations must be observed if you wish to mount snow chains. RSnow chains must not be mounted on emergency spare wheels. If you intend to mount snow chains, please bear the following points in mind: Ryou ! If snow chains are mounted on the front wheels, the snow chains could grind against the bodywork or components of the chassis. This could result in damage to the vehicle or the tires. ! Vehicles with steel wheels If you wish to mount snow chains to steel wheels, make sure that you remove the respective wheels' hubcaps first. The hubcaps may otherwise be damaged. i You may wish to deactivate ESP®(Y page 69) when pulling away with snow chains installed. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). You will find a table of recommended tire pressures on the Tire and Loading Information placard on the B-pillar on the driver's side (Y page 490). You will find a table of tire pressures for various operating conditions on the inside of your vehicle's fuel filler flap. Use a suitable pressure gauge. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitor, the tire pressure can be checked using the on-board computer. G Warning Should the tire pressure drop repeatedly: Z Tires and wheels may not attach snow chains to all wheel-tire combinations; see the "Tires and wheels" section in the "Technical data" chapter. Rmount snow chains only in pairs and only on the rear wheels. Observe the manufacturer's installation instructions.
