Practical hints Flat tire More information can be found in the "Technical data" section ( page 333). Preparing the vehicle Take vehicle tool kit tray and vehicle jack out of trunk. Take the spare wheel out of wheel well ( page 296). Lifting the vehicle Prevent the vehicle from rolling away by blocking wheels with wheel chocks (not included) or other sizable, heavy 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 behind the downhill sides of both wheels of the axle not being worked on. Warning! Take the two-piece wheel wrench out of the vehicle tool kit tray. Assemble wheel wrench. 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 level surface. Make sure that 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. 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. 309
