Notice: If a jack is used to raise the vehicle without
positioning it correctly, your vehicle could be
damaged. When raising your vehicle on a jack,
avoid contact with the rear axle control arms.
Notice: If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to
your vehicle. Always position the jack so that when
the jack head is raised, it will fit firmly in the
notch located inboard from the rocker molding.

vehicle's frame, inboard of the rocker molding.
Position the jack and raise the jack head until it fits
firmly into the notch in the vehicle's frame nearest
the flat tire.
Do not raise the vehicle yet.
