Damage to the tires or the vehicle may be the result. The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer's maintenance recommendation included with vehicle. i The following pages also list the approved wheel rim and tire sizes for equipping your vehicles with winter tires. Winter tires are not available as standard or optional factory equipment, but can be purchased from an authorized Mercedes-Benz Light Truck Center. Depending on vehicle model and the standard or optional factory-equipped wheel rim/tire configuration on your vehicle (Appearance Package, Sport Package etc.), equipping your vehicle with winter tires approved for your vehicle model may also require the purchase of two or four wheel rims of the recommended size for use with these winter tires. Contact an authorized Mercedes-Benz Light Truck Center for more information. i Further information on tires and rims is available at any authorized Mercedes-Benz Light Truck Center. A placard with the recommended tire inflation pressures is located on the driver's door B-pillar ( page 366). Some vehicles may have supplemental tire inflation pressure information for driving at high speeds ( page 372) or for vehicle loads less than the maximum loaded vehicle condition ( page 372). If such information is provided, it can be found on the placard located on the inside of the fuel filler flap. 529
