Practical hints Flat tire Storing collapsible spare wheel in wheel well Before you can store the spare wheel with collapsible tire in the wheel well you have to release the air pressure of the tire. Unscrew valve stem removal tool, which is part of the valve cap, from tire valve. Using the valve stem removal tool, open tire valve slightly by turning the tire valve insert counterclockwise to release air pressure. When the air pressure has been released, remove tire valve insert (protect it from dirt and sand) using the previously removed tire valve cap. Once all air is out of the tire, and the tire has collapsed to its original shape, reinstall the tire valve insert and valve cap. Place spare wheel in wheel well and secure it with the pump holder. Turn pump holder clockwise to its stop. Warning! G Warning! G 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. To prevent possible injury when unscrewing air pump filler hose from tire valve after inflating the tire, use a rag since the tire valve could be hot. Detach the electric air pump. Reinstall tire valve cap. Stow the electrical plug and the air hose behind the flap and place the air pump back in the trunk. Close the trunk lid. 244
