Digital Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset. If equipped, press
the reset stem and select to display
speed limit signs.
Trip
Turn the trip odometer reset stem
until TRIP displays. The current
distance traveled, in either
kilometers (km) or miles (mi), since
the last reset for the trip odometer is
shown. The trip odometer can be
reset to zero by pressing and
holding the trip odometer reset stem
while the trip odometer is displayed.
Fuel Range
This display shows the approximate
distance the vehicle can be driven
without refueling. The fuel range
estimate is based on an average of
the vehicle's fuel economy over recent driving history and the
amount of fuel remaining in the fuel
tank. Fuel range cannot be reset.
Average Fuel Economy
The Average Fuel Economy display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number reflects only the
approximate average fuel economy
that the vehicle has right now, and
will change as driving conditions
change. This number is based on
the number of L/100 km (mpg)
recorded since the last time this
menu item was reset. Reset this
display by pressing the trip
odometer reset stem.
Tire Pressure
Turn the trip odometer reset stem
until a vehicle with the approximate
pressures of all four tires displays.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per
square inch (psi).
See Tire Pressure Monitor System
0 399 and Tire Pressure Monitor
Operation 0 400 . Remaining Oil Life
Turn the trip odometer reset stem
until REMAINING OIL LIFE
displays. An estimate of the oil's
remaining useful life is shown.
REMAINING OIL LIFE 99% means
99% of the current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil 0 350 .
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule. See Maintenance
Schedule 0 448 .
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display at any time other than when
the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, see Engine
Oil Life System 0 353 .

DIC, use the trip odometer
reset stem to scroll to the Tire
Pressure screen.
5. If the vehicle has an uplevel
DIC, press and hold the
V(Set/Reset) button located in
the center of the DIC controls.
If the vehicle has a base level

6. Start with the driver side
front tire.
7. Place the relearn tool against
the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor. A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
8. Proceed to the passenger side
front tire, and repeat the
procedure in Step 7.
9. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 7.
10. Proceed to the driver side rear
tire, and repeat the procedure
in Step 7. The horn sounds two

identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
11. Turn the vehicle off.
12. Set all four tires to the
recommended air pressure
level as indicated on the Tire
and Loading Information label. Tire Inspection We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if: .
The indicators at three or
more places around the tire
can be seen. .
There is cord or fabric
showing through the tire's
rubber. .
The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric. .
The tire has a bump, bulge,
or split.
.
The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.

Vehicle Care 407Warning (Continued)wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the inner diameter of
the wheel hub opening with
wheel bearing grease after a
wheel change or tire rotation to
prevent corrosion or rust
build-up. Do not get grease on
the flat wheel mounting surface
or on the wheel nuts or bolts.
Reset the Tire Pressure Monitor
System (TPMS), if the vehicle
has one. See Tire Pressure
Monitor Operation 0 400 .
Check that the spare tire, if the
vehicle has one, is stored
properly. Push, pull, and then try
to rotate or turn the tire. If it
moves, tighten the cable. See “ Storing a Flat or Spare Tire and
Tools ” under Tire Changing
0 415 .
When It Is Time for New
Tires Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires. Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. See Tire
Inspection 0 404 and Tire Rotation
0 405 for additional information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. The
tire manufacture date is the last four
digits of the DOT Tire Identification
Number (TIN) which is molded into
one side of the tire sidewall. The
first two digits represent the week
(01-52) and the last two digits, the
year. For example, the third week of
the year 2010 would have a
four-digit DOT date of 0310.

Engine Oil Change When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See Engine Oil Life System 0 353 .
Passenger Compartment Air
Filter The passenger compartment air
filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
Inspect the passenger compartment
air filter every 36 000 km/
22,500 miles or two years,
whichever comes first. Replace if
necessary. More frequent
replacement may be needed if the
vehicle is driven in areas with heavy
traffic, areas with poor air quality,
or areas with high dust levels. Replacement may also be needed if
there is a reduction in air flow,
excessive window fogging, or odors.
