GMC SAVANA 2007 Owner's Manual

{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will
not move, you should put blocks at the
front and rear of the tire farthest away
from the one being changed. That would
be the tire, on the other side, at the
opposite end of the vehicle.When your vehicle has a flat tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following information will tell you next how to
use the jack and change a tire.

Removing the Spare Tire and Tools
If you have a cargo van or a passenger van,
the equipment you will need is located in
the passenger side rear corner of the vehicle.
Remove the retaining
wing bolt and lift it off of
the mounting bracket.
If you have a van with the 15-passenger seating
arrangement, the equipment you will need is
secured on the rear floor of the passenger side
of the vehicle.To access the equipment, remove the retaining
wing bolt and lift it out of the mounting bracket.
362

The tools you will be using include the jack (A),
jack handle extension (B), jack handle (C),
wheel wrench (D), and the ratchet (E).
The spare tire is stored underneath the rear of
your vehicle. You will use the wheel wrench (D)
and the ratchet (E) to lower the spare tire from
the vehicle.To lower the spare tire from the vehicle, do the
following:
1. Attach the wheel
wrench and ratchet,
with the DOWN side
facing you. The
wheel wrench has a
socket end and a flat
chisel end. Note that
there is an UP side
and a DOWN side on
the ratchet.
2. Put the flat chisel end of the wheel wrench on
an angle through the hole between the body
and the bumper. Be sure the flat end
connects into the hoist shaft.
363

3. Turn the ratchet counterclockwise to lower the
spare tire to the ground. If the spare tire does
not lower to the ground, the secondary
latch is engaged causing the tire not to lower.
SeeSecondary Latch System on page 371.4. When the tire has been lowered, pull the tire
toward you so you can reach the tire retainer
and pull it up through the wheel opening.
If you have a vehicle which was completed from a
cab and chassis, refer to the information from
the body supplier/installer.
The spare tire is a full-size tire, like the other tires
on your vehicle.
