Practical hints Flat tire The sticker must be attached on the instrument cluster where it will be easily seen by the driver. Vehicle handling characteristics of a TIREFIT repaired tire may change. Adapt your driving accordingly. X If the tire inflation pressure is at least 20 psi (1.3 bar), inflate or deflate the tire to the correct tire inflation pressure (see Tire and Loading Information placard on the driver's door B-pillar): located in air pump housing next to pressure gauge b. After driving the vehicle for an initial 10 minutes, check the tire inflation pressure using pressure gauge on the air pump. G Warning! If tire inflation pressure has fallen below 20 psi (1.3 bar) do not continue to drive the vehicle. Park your vehicle safely away from the roadway and contact the nearest authorized Mercedes-Benz Center or Roadside Assistance. Have the damaged tire replaced. Version 2 a Deflate button b Pressure gauge X To increase tire inflation pressure: Switch on the electric air pump. X Version 1: To decrease tire inflation pressure, open vent screw a on pressure gauge b (Y page 357). or X Version 2: To decrease tire inflation pressure, press yellow deflate button a G Warning! Follow recommend inflation pressures. Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes, etc. Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the pillar in the driver's door opening). Overloading the tires can overheat them, possibly causing a blowout. X Drive to the nearest qualified workshop, e.g. an authorized Mercedes-Benz Center, to have the damaged tire replaced. X Recommended duration of use: A maximum of 300 miles (500 km) at 50 mph (80 km/h) or below with the recommended tire inflation pressure. Z 359
