The DIC has different modes which can be accessed by
pressing the four DIC buttons located on the center
of the instrument panel, above the radio. These buttons
are fuel information, trip information, customization,
and select. The button functions are detailed in the
following pages.
Fuel Information Button
r
(Fuel Information):Press this button to scroll
through the fuel range, fuel used, average fuel economy,
and the engine oil life system.
Fuel Range:Press the fuel information button until
RANGE appears on the display. This mode shows the
remaining distance you can drive without refueling. It is
based on fuel economy and the fuel remaining in the fuel
tank. The display will show LOW if the fuel level is low.
The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your driving
conditions change, this data is gradually updated.
Fuel range cannot be reset.
Fuel Used:Press the fuel information button until
FUEL USED appears on the display. This mode shows
the number of gallons or liters of fuel used since the
last reset of this menu item. To reset the fuel used
information, press and hold the select button for
one second while FUEL USED is displayed.Average Fuel Economy:Press the fuel information
button until AVG. ECON appears on the display.
This mode shows how many miles per gallon (MPG),
kilometers per liter (km/L), or liters per 100 kilometers
(L/100 km) your vehicle is getting based on current and
past driving conditions.
Press and hold the select button for one second while
AVG. ECON is displayed to reset the average fuel
economy. Average fuel economy will then be calculated
starting from that point. If the average fuel economy is not
reset, it will be continually updated each time you drive.
Engine Oil Life System:Press the fuel information
button until ENGINE OIL LIFE appears on the display.
The engine oil life system shows an estimate of the oil’s
remaining useful life. It will show 100% when the
system is reset after an oil change. It will alert you to
change your oil on a schedule consistent with your
driving conditions.
Always reset the engine oil life system after an oil
change. To reset the engine oil life system, seeEngine
Oil Life System on page 5-22.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeeEngine
Oil on page 5-18andScheduled Maintenance on
page 6-4.

CHECK TIRE PRESSURE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle’s tires needs to be checked.
If a tire pressure message appears on the DIC, stop
as soon as you can. Have the tire pressures checked
and set to those shown on the Tire Loading Information
label. SeeTires on page 5-59,Loading the Vehicle
on page 4-21, andInflation - Tire Pressure on
page 5-65. The DIC also shows the tire pressure
values. SeeDIC Operation and Displays on page 3-42.
If the tire pressure is low, the low tire pressure
warning light comes on. SeeTire Pressure Light on
page 3-34.
CHECK WASHER FLUID
This message displays if the washer uid level is low.
Adding washer uid to the windshield washer uid
reservoir clears this message. SeeWindshield Washer

Cold Temperature Operation
Except Vehicles with 6.0L V8 (VIN Code H)
Engine
If in an area of extreme cold, where the temperature
falls below−20°F (−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at extremely low
temperatures. Always use an oil that meets the required
speci cation, GM6094M. See “What Kind of Engine
Oil to Use” for more information.
Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM standards are all
that is needed for good performance and engine
protection.
Engine oil system ushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when
to change the engine oil and lter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must
be reset every time the oil is changed.
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE ENGINE OIL message comes on in the
Driver Information Center (DIC). SeeDIC Warnings and
Messages on page 3-45. Change the oil as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if driving under the best conditions, the oil
life system might not indicate that an oil change is
necessary for over a year. However, the engine oil and
lter must be changed at least once a year and at this
time the system must be reset. Your dealer/retailer has
trained service people who will perform this work and
reset the system. It is also important to check the oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.
