Buick 2007 Rainier - Manual (Page 446)

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch
system. It is designed to stop the spare tire from
suddenly falling off your vehicle if the cable holding
the spare tire is damaged. For the secondary
latch to work, the tire must be stored with the valve
stem pointing up. See Storing a Flat or Spare
Tire and Tools on page 450 for instructions
on storing the spare or flat tire correctly.
{ 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 next.
{ 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.
