Practical hints Flat tire ! Please 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 tire to the recommended tire inflation pressure given on the yellow label on the spare wheel rim. Warning! G Lowering the vehicle Warning! Follow recommend tire 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. G Inflate collapsible tire only after the wheel is properly mounted. Inflate the collapsible tire using the electric air pump ( page 501) before lowering the vehicle. Press 0 on electric air pump switch 2. Turn the SmartKey in the starter switch to position 0. Vehicles with KEYLESS-GO*: Press the KEYLESS-GO start/stop button twice without depressing the brake pedal. If the tire inflation pressure is above the recommended tire inflation pressure given in this Operator's Manual, release excess tire inflation pressure using the vent screw. Lower vehicle by turning crank counterclockwise until vehicle is resting fully on its own weight. Remove the jack. Detach the electric air pump. Store the electrical plug and the air hose behind the flap and place the electric air pump back in the vehicle tool kit storage well. 1-5 Wheel bolts 503
