Practical hints Flat tire Mounting the spare wheel Preparing the vehicle Prepare the vehicle as described ( page 478). Take the wheel wrench and the vehicle jack from the vehicle tool kit ( page 455). Take the spare wheel from the wheel well under the cargo compartment floor ( page 458).

When changing wheel on a level surface: Place the wheel chock in front of and another sizable object behind the wheel that is diagonally opposite to the wheel being changed. Always try lifting the vehicle using the jack on a level surface. However, should circumstances require you to do so on a hill, place the wheel chock and another sizable object as follows: Place the wheel chock and another sizable object on the downhill side blocking both wheels of the axle not being worked on. 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 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. 479
