Practical hints Flat tire Lowering the vehicle Warning! Warning! Follow recommended tire inflation pressures. G G 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. Inflate the collapsible tire using the electric pump ( page 417) before lowering the vehicle. Lower vehicle by turning the crank counterclockwise until vehicle is resting fully on its own weight. Remove the jack. Tighten the five wheel bolts evenly in the direction of the arrow, following the diagonal sequence illustrated (1 to 5), until all bolts are tight. Observe a tightening torque of 80 lb-ft (110 Nm). Detach the electric air pump. Reinstall collapsible tire valve cap. Store electrical plug 3 and air hose 4 behind flap 1 and place the electric air pump back in the trunk.
