GMC 2009 Savana - Manual (Page 335)

5. Keep raising the jack until the spare tire stops
moving upward and is held firmly in place.
This lets you know that the secondary latch
has released. The spare tire is now balancing
on the jack.
6. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging
by the cable.
7. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, assembly
the wheel wrench onto the hoist extension and
insert the chisel end of the hoist extension into the
hoist shaft hole above the bumper. Turn the wheel
wrench counterclockwise to lower the spare the rest
of the way.
8. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
Notice: If you drive away before the spare tire or
secondary latch system cable has been reinstalled,
you could damage your vehicle. Always reinstall
this cable before driving your vehicle.
9. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been repaired or replaced.
To continue changing the flat tire, return to Step 4 of
Removing the Flat Tire and Installing the Spare Tire on
page 5-84.
