Buick 2007 Rainier Owner's Manual page 439

The following instructions explain how to remove
the underbody-mounted spare located underneath
your vehicle.
Notice: If you remove or restow a tire from/to
the storage position under the vehicle when
it is supported by a jack, you could damage the
tire and/or your vehicle. Always remove or
restow a tire when the vehicle is on the ground.
1. Open the liftgate. See Liftgate/Liftglass on
page 102 for more information.
2. Attach the wheel wrench (A) to the
extension (C).
3. It is exposed when the rear gate is open and
is just above the rear bumper.
Be sure the socket end of the extension (C)
connects to the hoist shaft (B).
4. Turn the wheel wrench counterclockwise to
lower the spare tire. Keep turning the wheel
wrench until the spare tire can be pulled
out from under the vehicle.
If the spare tire does not lower to the ground,
the secondary latch is engaged causing
the tire not to lower. See Secondary Latch
System on page 446 for more information.
