Practical hints Flat tire Lifting the vehicle Prevent the vehicle from rolling away by blocking wheels with wheel chocks (not included) or other sizable objects. When changing wheel on a level surface: Place one chock in front of and one behind the wheel that is diagonally opposite to the wheel being changed. When changing wheel on a hill: Place chocks on the downhill side blocking both wheels of the other axle. Warning! G The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into 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 a level surface. Make sure the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. 1 Wheel wrench On wheel to be changed, loosen but do not yet remove the wheel bolts (approximately one full turn with wrench). The jack take-up brackets are located directly behind the front wheel housings and in front of the rear wheel housings. 359
