Your vehicle was supplied with a jack for emergency road repairs. This jack is fine for changing a flat tire or other short-term procedures not requiring you to go beneath the vehicle. Do not attempt to use the jack on any portions of the vehicle other than specified by the vehicle manufacturer. Always block the diagonally opposite wheel when using a jack.
A more convenient way of jacking is the use of a garage or floor jack. You may use the floor jack on either side of he front of the vehicle by positioning the jack on the frame. However, it is usually easier to raise the front of the vehicle at the front crossmember.
At the rear of the vehicle, the jack can be positioned under the rear axle housing tubes, between the suspension arm brackets and the differential housing. Do not raise the rear of the vehicle using the differential housing as a lift point.
