The TPMS operates on a radio
frequency and complies with
RSS-210 of Industry and Science
Canada. Operation is subject to the
following two conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.
Changes or modi cations to this
system by other than an authorized
service facility could void
authorization to use this equipment.Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(TPMS) is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and
wheel assembly, excluding the
spare tire and wheel assembly. The
TPMS sensors monitor the air
pressure in the vehicle’s tires and
transmit the tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition
is detected, the TPMS turns on the
7
low tire pressure warning light.
At the same time a message to
check the pressure in a speci c tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
in ated to the correct in ation
pressure. Using the DIC, tire
pressure levels can be viewed bythe driver. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 4-22andDIC
Warnings and Messages on
page 4-26.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be in ated
to the proper pressure.
A Tire and Loading Information label
shows the size of the vehicle’s
original equipment tires and the
correct in ation pressure for the
vehicle’s tires when they are cold.
SeeLoading the Vehicle on
page 8-30, for an example of the Tire
and Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 9-49.
9-54 Vehicle Service and Care
Page 259 of 356
The vehicle’s TPMS system can
warn about a low tire pressure
condition but it does not replace
normal tire maintenance. See
Tire Inspection and Rotation on
page 9-57andTires on page 9-42.
Notice:Using non-approved
tire sealants could damage
the Tire Pressure Monitor System
(TPMS) sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle warranty.
Always use the GM approved
tire sealant available through your
dealer/retailer.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS
sensors are missing or not
operating.
When the system detects a
malfunction, the
7low tire warning
light ashes for about one minute
and then stays on for the remainderof the ignition cycle. A DIC warning
message also displays. The low tire
warning light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause the malfunction light and DIC
message to come on are:
One of the road tires has been
replaced with the spare tire. The
spare tire does not have a TPMS
sensor. The TPMS malfunction
light and DIC message should go
off once the road tire containing
the TPMS sensor is re-installed.
The TPMS sensor matching
process was started but not
completed or not completed
successfully after installing
replacement tires or rotating the
vehicle’s tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process is
performed successfully.
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 the dealer/
retailer for service.
Replacement tires or wheels do
not match the vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for the vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 9-59.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
Vehicle Service and Care 9-55
Page 260 of 356
If the TPMS is not functioning it
cannot detect or signal a low
tire condition. See the dealer/retailer
for service if the TPMS malfunction
light and DIC message comes
on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identi cation code. Any time one or
more of the TPMS sensors are
replaced or the vehicle’s tires are
rotated, the identi cation codes
need to be matched to the
new tire/wheel location. The sensors
are matched, to the tire/wheel
locations, 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. When increasing
the tire’s pressure, do not exceed
the maximum in ation pressure
indicated on the tire’s sidewall. To
decrease the tire’s air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match
each tire and wheel position.
If it takes longer than two minutes to
match any tire and wheel position,
the matching process stops and you
need to start over.
The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press and hold the Remote
Keyless Entry (RKE) transmitter’s
lock and unlock buttons, at the
same time, for about ve secondsto start the TPMS learn mode.
The horn chirps two times
indicating the TPMS receiver is
ready and in learn mode.
4. Start with the driver side front
tire. The driver side front
indicator lamp also comes on to
indicate that corner’s sensor
is ready to be learned.
5. Remove the valve cap from the
tire’s valve stem. Activate the
TPMS sensor by increasing
or decreasing the tire’s air
pressure for about eight seconds.
The horn chirps one time to
con rm the sensor identi cation
code has been matched to
the tire/wheel position.

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 ofmost 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
speci ed 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 signi cantly from the norm
due to variations in driving habits,
service practices, and differences
in road characteristics and
climate.

8. Check the air pressure gage (G).
If there is not a pressure reading
while the compressor is running,
check for leaks at the connection
between the tire valve stem and
the sealant/air hose (E).
9. In ate the tire to the
recommended in ation pressure,
found on the Tire and Loading
Information label. See
Inflation - Tire Pressure on
page 9-49.
The pressure gage (G) will
initially read high while the
compressor injects the sealant
into the tire. Once the sealant
injection is complete, the
pressure will quickly drop. It will
start to rise again as the tire
in ates with air.10. Turn the compressor off by
pushing the On/Off button (A)
to the I (off) position.
The pressure gage (G) reads
slightly high while the
compressor is on. Turn the
compressor off to get an
accurate reading. The
compressor may be turned on
and off until the correct pressure
is reached.
Notice:If the recommended
pressure cannot be reached after
approximately 15 minutes, the
vehicle should not be driven. The
tire is too severely damaged and
the tire sealant and compressor kit
cannot in ate the tire. Remove the
air compressor accessory plug
from the accessory power outlet
and unscrew the sealant/air hose
from the tire valve or tire pressure
monitoring sensor valve. See
Roadside Assistance Program on
page 12-6.The tire is not sealed and will
continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire.
Steps 11 through 19 must be
done right after Step 10.
Be careful while handling the
tire sealant and compressor kit
as they could be hot after
usage.
11. Unplug the air compressor
accessory plug (B) from the
accessory power outlet in
the vehicle.
12. Turn the sealant/air hose (E)
counterclockwise to remove.
13. Replace the tire valve
stem cap.
14. Stow the sealant/air hose (E)
and air compressor accessory
plug (B) in their original
locations.

6. Push the On/Off switch (G) to
the I (on) position.
Check the pressure gage (F).
If there is not a pressure reading
while the compressor isrunning, check for leaks at the
connection between the
hose and the tire valve stem.
7. In ate the tire up to the
recommended in ation pressure
using the air pressure gage (F)
on the top of the unit. See
Inflation - Tire Pressure on
page 9-49.
The pressure gage (F) reads
slightly high while the compressor
is on. Turn the compressor off to
get an accurate reading. The
compressor may be turned on
and off until the correct pressure
is reached.
8. Push the On/Off switch (G) to
the O (off) position.
Be careful while handling the tire
sealant and compressor kit as
they could be hot after usage.
9. Unplug the air compressor

cause battery gas to explode.
People have been hurt doing this,
and some have been blinded. Use
a ashlight if you need more light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has ller caps, be sure the right
amount of uid is there. If it is
low, add water to take care of that
rst. If you don’t, explosive gas
could be present.
Battery uid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, ush
the place with water and get
medical help immediately.

Successful, safe trailering takes
correct equipment, and it has
to be used properly.
That is the reason for this part. In it
are many time-tested, important
trailering tips and safety rules. Many
of these are important for your
safety and that of your passengers.
So please read this section
carefully before you pull a trailer.
Load-pulling components such
as the engine, transmission, wheel
assemblies and tires are forced
to work harder against the drag of
the added weight. The engine
is required to operate at relatively
higher speeds and under greater
loads, generating extra heat.
Also, the trailer adds considerably to
wind resistance, increasing the
pulling requirements.If You Do Decide To Pull A
Trailer
If you do, here are some important
points:
There are many different laws,
including speed limit restrictions,
having to do with trailering. Make
sure your rig will be legal, not only
where you live but also where you
will be driving. A good source for
this information can be state or
provincial police.
Consider using a sway control.
You can ask a hitch dealer about
sway controls.
Do not tow a trailer at all during
the rst 1,000 miles (1 600 km)
your new vehicle is driven. Your
engine, axle or other parts could
be damaged.
Then, during the rst 500 miles
(800 km) that you tow a trailer, do
not drive over 50 mph (80 km/h)
and do not make starts at fullthrottle. This helps your engine
and other parts of your vehicle
wear in at the heavier loads.
Use the Sport Shift mode and the
cruise control when towing. The
Active Select (A/S) may also be
used under light load conditions.
Obey speed limit restrictions
when towing a trailer. Do not drive
faster than the maximum posted
speed for trailers, or no more than
55 mph (90 km/h), to save wear
on your vehicle’s parts.
Three important considerations have
to do with weight:
The weight of the trailer.
The weight of the trailer tongue.
The total weight on your
vehicle’s tires.
9-90 Vehicle Service and Care
Page 296 of 356
Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are
in ated to the upper limit for cold
tires. You will nd these numbers on
the Tire-Loading Information label.
SeeLoading the Vehicle on
page 8-30. Then be sure you do not
go over the GVW limit for your
vehicle, including the weight of the
trailer tongue.
Hitches
It is important to have the correct
hitch equipment. Crosswinds,
large trucks going by and rough
roads are a few reasons why
you will need the right hitch. Here
are some rules to follow:
The rear bumper on your vehicle
is not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
Will you have to make any holes
in the body of your vehicle when
you install a trailer hitch? If you
do, then be sure to seal the holes
later when you remove the hitch.
If you do not seal them, deadly
carbon monoxide (CO) from your
exhaust can get into your vehicle.
SeeEngine Exhaust on
page 8-14. Dirt and water can
also enter the vehicle.
Safety Chains
You should always attach chains
between your vehicle and your
trailer. Cross the safety chains under
the tongue of the trailer so that the
tongue will not drop to the road if it
becomes separated from the hitch.
Instructions about safety chains may
be provided by the hitch
manufacturer or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains and do not
attach them to the bumper. Alwaysleave just enough slack so you can
turn with your rig. And, never allow
safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer
brakes so you will be able to install,
adjust and maintain them properly.
Because you have anti-lock brakes,
do not tap into your vehicle’s brake
system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required
for your trailer lighting system can be
accessed at the driver’s side rear
lamp connector. This connector is
located under the carpet on the rear
corner of the trunk compartment.
