Practical hints Flat tire ! Do not operate the air pump longer than eight minutes without interruption. Otherwise it may overheat. You may operate the air pump again after it has cooled off. Press 0 on the electric air pump switch. Turn the key in the ignition to position 0. or Press KEYLESS-GO* start/stop button on the selector lever twice without depressing the brake pedal. The electric air pump should now be switched off. If the tire pressure is above 36 psi (2.5 bar), release excess tire pressure using the vent screw. Detach the electric air pump. Stow the electrical plug and the air hose behind the flap and place the air pump back in the trunk. 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. i The flat tire may be transported in the trunk when the retractable hardtop is lowered. Use the protective sheet provided with the spare wheel. Do not activate the tire inflation pressure monitor until the deflated tire has been removed from the vehicle. 317
