Practical hints Flat tire Press I on electric air pump switch 2. The electric air pump switches on and inflates the collapsible tire. Inflate the collapsible tire to approximately 51 psi (3.5 bar). This takes about 5 minutes. Air hose 4 and union nut 5 can become hot during inflation. Exercise proper caution to avoid burning yourself when using the equipment. ! Do not operate the electric air pump longer than 6 minutes without interruption. Otherwise it may overheat. You may operate the electric air pump again after it has cooled off. Warning! Follow recommended tire inflation pressures. G Press 0 on electric air pump switch 2. Turn the SmartKey in the starter switch to position 0. The electric air pump is switched off. If the tire inflation pressure is above 51 psi (3.5 bar), release excess tire inflation pressure using the vent screw on air hose 4. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. ! Compare the recommended tire inflation pressure for your vehicle with the tire inflation pressure on the yellow label located on the spare wheel rim. If the tire inflation pressure on the yellow label on the spare wheel rim differs from the values given in this Operator's Manual, inflate the collapsible tire to the recommended tire inflation pressure given on the yellow label on the spare wheel rim. Detach the electric air pump. Reinstall tire valve cap. Store electrical plug 3 and air hose 4 behind flap 1 and place the electric air pump back in the trunk. Lower the vehicle ( page 413). 412
