flat tire GMC ACADIA 2008 User Guide

Secondary Latch System
Your 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 your 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.
SeeStoring a Flat or Spare Tire and Tools on page 5-84
for instructions on storing the spare 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.
To release the spare tire from the secondary latch:
{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 under spare.
1. If the cable is not visible, start this procedure at
Step 3.

Storing a Flat or Spare Tire and
Tools
Storing the Spare Tire
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down. If
the spare tire is stored with the valve stem
pointing upwards, its secondary latch will not
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing down.
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
To store the spare tire:
1. Lay the compact spare tire near the rear of the
vehicle with the valve stem down.
2. Reinstall the plastic spare tire heat shield on the
compact spare tire.
3. Slide the cable retainer through the center of the
wheel and start to raise the compact spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
4. When the compact spare tire is almost in the stored
position, turn the tire so the valve is toward the rear
of the vehicle.
This position helps when checking the air pressure
in the compact spare tire.

5. Raise the tire fully against the underside of the
vehicle. Continue turning the lug wrench until
you feel more than two clicks. This indicates that
the compact spare tire is secure and the cable
is tight. The spare tire hoist cannot be
overtightened.
6. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the lug wrench to tighten the cable.Storing the Flat Tire
Notice:Storing the full-size at tire in the
underbody hoist system can expose it to heat from
the exhaust system. This can damage the tire
and underbody hoist system. Do not store the
full-size at tire in the underbody hoist system.
1. Remove the cable package from the jack
storage area.
2. Remove the small center cap by tapping the back
of the cap with the extension of the shaft, if the
vehicle has aluminum wheels.
3. Put the at tire in the rear storage area with the
valve stem pointing toward the rear of the vehicle.
