Secondary Latch System - GMC Acadia 2011 Owner's Manual

10-82 Vehicle Care

Secondary Latch System

This vehicle has an underbody
mounted tire hoist assembly that
has a secondary latch system.
It is designed to stop the compact
spare tire from suddenly falling off
the vehicle if the cable holding the
spare tire is damaged. For the
secondary latch to work, the tire
must be stowed with the valve stem
pointing down. See Tire Changing
on page 10 72 for instructions on
storing the spare tire correctly.
WARNING
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 next.
To release the spare tire from the
secondary latch:
WARNING
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
under the spare.
1. If the cable is not visible, start
this procedure at Step 3.
