2008 CHEVROLET EXPRESS flat tire

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 the 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 6-100for instructions on storing the spare tire
correctly.
{WARNING:
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:
{WARNING:
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 under the spare.
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible, start this
procedure at Step 6.
2. Turn the hoist extension counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.

6. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging
by the cable.
7. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, assembly
the wheel wrench onto the hoist extension and insert
the chisel end of the hoist extension into the hoist
shaft hole above the bumper. Turn the wheel wrench
counterclockwise to lower the spare the rest of
the way.8. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
Notice:If you drive away before the spare tire or
secondary latch system cable has been reinstalled,
you could damage your vehicle. Always reinstall
this cable before driving your vehicle.
9. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been repaired or replaced.
To continue changing the flat tire, return to Step 4 of
Removing the Flat Tire and Installing the Spare Tire on
page 6-90.

Storing a Flat or Spare Tire and
Tools
{WARNING:
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.
1. Put the tire on the ground at the rear of the vehicle
with the valve stem pointed down.2. Pull the retaining bar through the center of the
wheel, making sure it is properly attached.
3. Pull the wheel toward the rear of the vehicle,
keeping the cable tight.
4. Put the chisel end of the hoist extension on an
angle through the hole in the rear door frame,
above the bumper.
5. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until
the tire is secure and the cable is tight. The spare
tire hoist cannot be overtightened.
6-100

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 wheel wrench to tighten the cable.
You will hear two clicks when the tire is up all
the way.
7. Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.
Spare Tire
This vehicle, when new, may have had a fully-inflated
spare tire. A spare tire may lose air over time, so check its
inflation pressure regularly. SeeInation - Tire Pressure
on page 6-68andLoading the Vehicle on page 5-19for
information regarding proper tire inflation and loading the
vehicle. For instruction on how to remove, install or store
a spare tire, seeRemoving the Flat Tire and Installing the
Spare Tire on page 6-90andStoring a Flat or Spare Tire
and Tools on page 6-100.
After installing the spare tire on the vehicle, you should
stop as soon as possible and make sure the spare is
correctly inflated. The spare tire is made to perform well
at speeds up to 70 mph (112 km/h) at the recommended
inflation pressure, so you can finish your trip.
Have the damaged or flat road tire repaired or replaced
as soon as you can and installed back onto the vehicle.
This way, a spare tire will be available in case you need
it again. Do not mix tires and wheels of different sizes,
because they will not fit. Keep the spare tire and its
wheel together.
