2009 CHEVROLET TRAIL BLAZER Owners Manual

Secondary Latch System
This vehicle may have an underbody-mounted tire
hoist assembly equipped with a secondary latch system.
It is designed to stop the spare tire, if the vehicle has one,
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 stored with the valve stem pointing
up. SeeStoring a Flat or Spare Tire and Tools on
page 5-106for instructions on storing the spare or at
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.
{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.
To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable is visible. If it is
not visible, proceed
to Step 6.
5-103

2. If visible, rst try to tighten the cable by turning the
wheel wrench clockwise until you hear two clicks or
feel it skip twice. You cannot overtighten the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with
Step 2 ofRemoving the Spare Tire and Tools on
page 5-94.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.
6. Attach the jack handle, extension(s) and the wheel
wrench to the jack and place it under the vehicle
towards the front of the rear bumper. Position
the center lift point of the jack under the center
of the spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
8. Continue raising the jack until the spare tire
stops moving upward and is held rmly in place.
The secondary latch has released and the spare
tire is balancing on the jack.
5-104

9. 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.
10. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while rmly pulling the jack out
from under the spare tire with the other hand.
11. If the spare tire is
hanging from the cable,
insert the socket end of
the extension into the
hoist shaft hole on a
45 degree angle
downward.
12. Be sure that the socket end of the extension
connects to the hoist shaft.Turn the wheel wrench counterclockwise to lower
the spare the rest of the way.
13. 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.
14. Turn the wheel wrench clockwise to raise the cable
back up if the cable is hanging under the vehicle.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare tire using the
hoist assembly until it has been repaired or replaced.

Storing a Flat or Spare Tire and
Tools
{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.
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing up. If the
spare tire is stored with the valve stem pointing
downward, 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 up.
Notice:An aluminum wheel with a at tire should
always be stored under the vehicle with the hoist.
However, storing it that way for an extended period
could damage the wheel. To avoid this, always stow
the wheel properly with the valve stem pointing up
and have the wheel repaired as soon as possible.

hole just above the rear bumper at a 45 degree
angle downward. Connect the socket end of
the extension to the hoist shaft (B).
6. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench (A)
clockwise until you hear two clicks or feel it skip
twice. This indicates that the tire is secure and
the cable is tight. The spare tire hoist cannot be
overtightened.

Spare Tire
This vehicle may have a spare tire. Although the
spare tire was fully inated when the vehicle was new,
it can lose air after a time. Check the ination pressure
regularly. SeeInflation - Tire Pressure on page 5-65
andLoading the Vehicle on page 4-33for information
regarding proper tire ination and loading your vehicle.
For instruction on how to remove, install or store a spare
tire, seeRemoving the Flat Tire and Installing the Spare
Tire on page 5-97andStoring a Flat or Spare Tire and
Tools on page 5-106.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. The spare tire is made to perform well
at speeds up to 70 mph (112 km/h) at the recommended
ination pressure, so you can nish your trip.
Have the damaged or at road tire repaired or replaced
as soon as you can and installed back onto your 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 t. Keep your spare tire and its
wheel together.
Appearance Care
Interior Cleaning
The vehicle’s interior will continue to look its best if it is
cleaned often. Although not always visible, dust and
dirt can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from the
upholstery. It is important to keep the upholstery from
becoming and remaining heavily soiled. Soils should be
removed as quickly as possible. The vehicle’s interior
may experience extremes of heat that could cause
stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to home furnishings may also
transfer color to the vehicle’s interior.
5-109

When cleaning the vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:Using abrasive cleaners when cleaning
glass surfaces on the vehicle, could scratch
the glass and/or cause damage to the rear window
defogger. When cleaning the glass on the vehicle,
use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in the vehicle’s breathing space. Before
using cleaners, read and adhere to all safety instructions
on the label. While cleaning the vehicle’s interior,
maintain adequate ventilation by opening the vehicle’s
doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.Products that remove odors from the vehicle’s
upholstery and clean the vehicle’s glass can be
obtained from your dealer/retailer.
Do not clean the vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops
per gallon (3.78 L) of water is a good guide.
Use only mild, neutral-pH soaps.
Too much cleaner that saturates the upholstery.
Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
