Secondary Latch System
This 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.
See“Storing a Flat or Spare Tire
and Tools” underTire Changing on
page 10‑74 for 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 15 cm (6 in) of
cable is exposed.

3. Attach the jack handle/jackhandle extension and wheel
wrench to the jack.
4. Place the jack under the vehicle,ahead of the rear bumper.
Position the center lift point of
the jack under the center of the
spare tire and turn the handle
clockwise to raise the jack until it
lifts the secondary latch spring.
5. Keep raising the jack until the spare tire stops moving upward
and is held firmly in place. This
lets you know that the secondary
latch has released. The spare
tire is now balancing on the jack. 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.

Vehicle Care 10-85
Notice:If you drive away before
the spare tire or secondary latch
system cable has been
reinstalled, you could damage the
vehicle. Always reinstall this
cable before driving the 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 “Storing a Flat or
Spare Tire and Tools” underTire
Changing on page 10‑74.Full-Size 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. See Tire Pressure on
page 10‑56 andVehicle Load Limits
on page 9‑11 for information
regarding proper tire inflation and
loading the vehicle. For instruction
on how to remove, install or store a
spare tire, see “Removing the Flat
Tire and Installing the Spare Tire”
and “Storing a Flat or Spare Tire
and Tools” underTire Changing on
page 10‑74. 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 112 km/h (70 mph) 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.

10-96 Vehicle Care
Steering, Suspension, and
Chassis Components
Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect power
steering lines and hoses for proper
hook-up, binding, leaks, cracks,
chafing, etc. Visually check constant
velocity joints, rubber boots, and
axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and
steel fuel door hinge unless the
components are plastic. Applying
silicone grease on weatherstrips
with a clean cloth will make them
last longer, seal better, and not stick
or squeak.
Underbody Maintenance
Use plain water to flush dirt and
debris from the vehicle's underbody.
Your dealer or an underbody car
washing system can do this. If not
removed, rust and corrosion can
develop.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon
and attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.

Vehicle Data
Recording and
Privacy
This GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, the vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash, and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help your dealer technician
service the vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio presets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment or
hitting a road obstacle, data that will
assist in understanding how a
vehicle's systems performed. The
EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period of
time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
.How various systems in the
vehicle were operating.
.Whether or not the driver and
passenger safety belts were
buckled/fastened.
.How far, if at all, the driver was
pressing the accelerator and/or
brake pedal.
.How fast the vehicle was
traveling.
