Buick 2005 Terraza - Manual (Page 365)

Your vehicle uses the underbody tire hoist assembly
to store either the compact spare or a flat road tire. See
Storing a Flat or Spare Tire and Tools on page 5-74
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 below.
{ 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.
To release the spare tire from the secondary latch,
do the following:
1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch device under the
wheel plate.
3. Keep raising the jack until the compact spare tire
stops moving upward and is held firmly in place.
This lets you know that the secondary latch
has released.
