counterclockwise. Keep lowering the jack until the
spare tire slides off the jack or is hanging by
the cable.

the bumper on a 45 degree angle downward.
Turn the wheel wrench counterclockwise to lower
the spare the rest of the way.

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.

back up if the cable is hanging under the vehicle.
