3. Locate the vehicle’s jacking
positions (A and B).
4. Assemble the jack and tools as follows:
Front Tire Flat: If the flat tire is on a front tire
of the vehicle, you will need to use the jack
handle and both jack handle extensions. Attach
the wheel wrench to the jack handle
extensions. Attach the jack handle to the jack.
From the front of the vehicle position the
jack on the front lower control arm along the
bar that runs front to back. Turn the wheel
wrench clockwise to raise the vehicle. Raise
the vehicle far enough off the ground so
there is enough room for the spare tire to clear
the ground.
