Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch system.
It’s designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work, the
spare must be installed with the valve stem pointing
down. See “Storing a Flat or Spare Tire, Jack and Tools”
earlier in this section.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed below.
To release the spare tire from the secondary latch do
the following: Suburban

11. 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.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If the
spare tire does not slide off the jack completely,
make sure no one is behind you or on either
side of you as you pull the jack out from
the spare.
12. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while rmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert
the hoist handle, extension and wheel wrench into
the hoist shaft hole in the bumper and turn the
wheel wrench counterclockwise to lower the spare
the rest of the way.13. Tilt the retainer (D) at
the end of the cable
and pull it through
the wheel opening. Pull
the tire out from
under the vehicle.
14. 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 at tire using
the hoist assembly until it has been replaced.
To continue changing the at tire, see “Removing
the Flat Tire and Installing the Spare Tire” earlier in
this section.
