2009 CHEVROLET TRAIL BLAZER light

One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-75.
Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer
for service if the TPMS malfunction light and DIC
message come on and stay on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identication code.
Any time you rotate your vehicle’s tires or replace one
or more of the TPMS sensors, the identication codes
will need to be matched to the new tire/wheel position.
The sensors are matched to the tire/wheel positions in
the following order: driver side front tire, passenger side
front tire, passenger side rear tire, and driver side rear tire
using a TPMS diagnostic tool. See your dealer/retailer for
service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. If increasing the tire’s air pressure, do
not exceed the maximum ination pressure indicated
on the tire’s sidewall.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gage, or a key.
5-71

You have two minutes to match the rst tire/wheel
position, and ve minutes overall to match all four
tire/wheel positions. If it takes longer than two minutes, to
match the rst tire and wheel, or more than ve minutes
to match all four tire and wheel positions the matching
process stops and you need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Turn the headlamp control from off to parking lamps
four times within three seconds. A double horn chirp
will sound and the TPMS low tire warning light will
begin to ash. The double horn chirp and ashing
TPMS warning light indicate that the TPMS matching
process has started. The TPMS warning light should
continue ashing throughout the matching
procedure.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.The single horn chirp should sound within
15 seconds, conrming that the sensor identication
code has been matched to this tire and wheel
position. If you do not hear the conrming single
horn chirp, you will need to start over with
step number one.
6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5.
9. After hearing the conrming horn chirp for the
driver’s side rear tire, check to see if the TPMS
warning light is still ashing. If yes, turn the ignition
switch to LOCK/OFF to exit the sensor matching
process. If the TPMS warning light is not ashing,
the ve minute time limit has passed and you
will need to start the process over beginning with
Step 1.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the
system developed by the United States National
Highway Traffic Safety Administration (NHTSA),
which grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters
of 10 to 12 inches (25 to 30 cm), or to some
limited-production tires.While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.

3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-19.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (C) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completelydispersed into the tire, the pressure will quickly
drop and start to rise again as the tire inates
with air only.
10. Inate the tire to the recommended ination
pressure using the pressure gage (C).
The recommended ination pressure can
be found on the Tire and Loading Information
label. SeeInflation - Tire Pressure on page 5-65.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate pressure
reading. The compressor may be turned on/off
until the correct pressure is reached.
Notice:If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot inate the tire. Remove the power plug from
the accessory power outlet and unscrew the inating
hose from the tire valve. SeeRoadside Assistance
Program on page 7-7.
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant
is distributed in the tire, therefore, Steps 12 through
18 must be done immediately after Step 11.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.

4. Remove the tire valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem
by turning it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-19.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) clockwise to the Air
Only position.
9. Press the on/off (B) button to turn the
compressor on.
The compressor will inate the tire with air only.10. Inate the tire to the recommended ination
pressure using the pressure gage (C). The
recommended ination pressure can be found
on the Tire and Loading Information label.
SeeInflation - Tire Pressure on page 5-65.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.
If you inate the tire higher than the recommended
pressure you can adjust the excess pressure
by pressing the pressure deation button (D),
if equipped, until the proper pressure reading
is reached. This option is only functional when
using the air only hose (G).
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.

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

Washing Your Vehicle
The best way to preserve the vehicle’s nish is to keep
it clean by washing it often.
Notice:Certain cleaners contain chemicals that can
damage the emblems or nameplates on the vehicle.
Check the cleaning product label. If it states that
it should not be used on plastic parts, do not use it
on the vehicle or damage may occur and it would
not be covered by the warranty.
Do not wash the vehicle in direct sunlight. Use a car
washing soap. Do not use cleaning agents that are
petroleum based or that contain acid or abrasives, as
they can damage the paint, metal or plastic on the
vehicle. Approved cleaning products can be obtained
from your dealer/retailer. Follow all manufacturers’
directions regarding correct product usage, necessary
safety precautions and appropriate disposal of any
vehicle care product.Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the nish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting.
High pressure car washes may cause water to enter
the vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a
car washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle on
page 5-113.
5-113

Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of the vehicle that
you can get along without — like the radio or cigarette
lighter — and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the engine
compartment on the driver side of the vehicle. See
Engine Compartment Overview on page 5-12for more
information on location.
Remove the primary cover by pressing the two locking
tabs. Remove the secondary cover by snapping off
while lifting. To reinstall the fuse panel cover, reverse
the sequence.
Notice:Spilling liquid on any electrical components
on the vehicle may damage it. Always keep the
covers on any electrical component.
