The vehicle capacity weight (max. load), the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Ratings (GAWR) for front and rear, are listed on a sticker located on the

doorsill on the driver's side.

The gross vehicle weight rating includes the weight of the basic vehicle plus full fuel tank, oil and coolant, plus max. load which combines passenger (150 pounds/68 kg per designated

seating position) and luggage weight. Luggage weight may not be increased by the use of roof, ski or luggage racks, unless passenger capacity is reduced accordingly.

The load rating and the code letter for maximum permissible speed (e. g. 88 Q) are minimum

requirements. When buying new tires or changing tires, follow the instructions in the

section "Tires and Tire Care".

To ensure that the tire pressure warning system operates properly, rims with pressure

switches must be used.
