Practical hints Flat tire Warning! G The jack is designed exclusively for jacking up the vehicle at the jack tubes built both sides of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical (plumb line) when in use, especially on hills. Always try to use the jack on level surface. Make sure that the jack arm is fully inserted in the jack tube. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Take the two-piece wheel wrench out of the vehicle tool kit tray. Assemble wheel wrench. On wheel to be changed, loosen but do not yet remove the wheel bolts (approximately one full turn with wrench). The tube openings are located directly behind the front wheel housings and in front of the rear wheel housings. 1 Jack support tube cover Move cover 1 toward rear by pressing at point indicated by arrow.
