Battery
Your vehicle has a maintenance free battery. It is
located in the trunk, behind the trim panel, on the
passenger side of the vehicle. When it is time for a
new battery, see your dealer/retailer for one that has
the replacement number shown on the original battery’s
label.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
After a power loss, such as disconnecting the battery or
removing the maxi fuses in the power distribution fuse
block, the following steps must be performed to calibrate
the electronic throttle control. If this is not done, the
engine will not run properly.
1. Turn the ignition to ON/RUN. Do not start the
engine.
2. Leave the ignition in ON/RUN for at least
three minutes so that the electronic throttle
control will cycle and re-learn its home position.
3. Turn the ignition to LOCK/OFF.
4. Start and run the engine for at least 30 seconds.
Vehicle Storage
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on page 5-45
for tips on working around a battery without
getting hurt.
Infrequent Usage: If you drive your vehicle infrequently,
remove the black, negative (−) cable from the battery.

to obtain service, see your vehicle Warranty
booklet for details.
{CAUTION:
Poorly maintained and improperly
used tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
exing. You could have an air-out and
a serious accident. SeeLoading the
Vehicle on page 4-22.
CAUTION: (Continued)
5-58

TPMS Sensor Matching Process
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors
or rotate your vehicle’s tires, the identication codes
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 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 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 matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE) transmitter’s
lock and unlock buttons at the same time for
approximately ve seconds. The horn sounds twice
to signal the receiver is in relearn mode and Tire
Learning Active message displays on the DIC
screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
or until a horn chirp sounds. The horn chirp, which
can take up to 30 seconds to sound, conrms
that the TPMS sensor identication code has
been matched to this tire position.
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.
5-73

9. After hearing the conrming horn chirp, for the
driver side rear tire, the horn sounds two more
times to signal the tire learning mode is no longer
active. Turn the ignition switch to LOCK/OFF.
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.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs
of wear or damage. SeeWhen It Is Time for New
Tires on page 5-75for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform most
like it did when the tires were new.
If your vehicle has 235/50ZR18 size tires, GM
recommends rotating these tires at 3,000 mile
(4 800 km) intervals. These tires are optimized fordry traction and handling performance. Tread life
may be 15,000 miles (24 140 km) or less for these
tires, depending on how and where you drive.
Any time you notice unusual wear, rotate your
vehicle’s tires as soon as possible and check
wheel alignment. Also check for damaged tires
or wheels. SeeWhen It Is Time for New Tires on
page 5-75andWheel Replacement on page 5-80
for more information.
When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
If your vehicle has a compact spare tire, do not
include it in the tire rotation.
5-74

Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may affect
the way your vehicle performs, including its braking, ride
and handling characteristics, stability, and resistance
to rollover. Additionally, if your vehicle has electronic
systems such as, antilock brakes, traction control, and
electronic stability control, the performance of these
systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will crash
and suffer serious injury. Only use GM specic
wheel and tire systems developed for your
vehicle, and have them properly installed
by a GM certied technician.
SeeBuying New Tires on page 5-76andAccessories
and Modifications on page 5-4for additional information.
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.

turning the wing nut (C counterclockwise).
4. Remove the sealant and compressor kit from its
foam container (B).
Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal small punctures in the
tread area of the tire. The sealant cannot seal sidewall
damage, large punctures, or a tire that has unseated
from the wheel. SeeRoadside Service on page 7-7if
you need assistance.
The sealant can only be used to seal one tire. After
usage, the sealant canister and sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in
this section.
Check the tire sealant expiration date on the sealant
canister. The sealant might not be effective beyond
the expiration date. If needed, see your dealer/retailer
for a replacement canister.

{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-48.
7. Start the vehicle. SeeStarting the Engine on
page 2-35for more information. The vehicle must
be running while using the air compressor.
{CAUTION:
Overination could cause the tire to rupture,
and you or others could be injured. Be sure to
read the inator instructions, and inate the
tire to its recommended pressure. Do not
exceed 36 psi (248 kPa).
8. Turn the selector switch (A) counterclockwise to the
sealant and air position.9. Push the On/Off button (B).
The sealant and compressor kit will inject sealant
and air into the tire. Sealant may leak from the
puncture until the vehicle is driven and the hole
has sealed.
The pressure gage (C) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completely
dispersed into the tire, the pressure will quickly drop
and start to rise again as the tire inates with air.
10. Inate the tire to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air pressure
gage on the top of the unit.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate pressure reading.
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 air compressor
plug from the accessory power outlet and unscrew
the inating hose from the tire valve. SeeRoadside
Service on page 7-7.
11. Turn the compressor off by pushing the On/Off
button (B).
