Practical hints Flat tire 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. X Version 2 a Deflate button b Pressure gauge X To increase tire inflation pressure: Switch on the electric air pump.

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 Contact an authorized Mercedes-Benz Center as soon as possible to obtain a new TIREFIT kit.
