28 In Brief
Fuel (Gasoline - L87 6.2L
Engine) Premium Recommended
Use premium 93 octane —
(R+M)/2 — unleaded gasoline in
your vehicle. TOP TIER Detergent
Gasoline is recommended.
Unleaded gasoline with an octane
rating as low as 87 may be used,
but it will reduce performance and
fuel economy.
See Recommended Fuel (Except
6.2L V8 Engine) 0 271 or
Recommended Fuel (6.2L
V8 Engine) 0 271 .
Fuel (Diesel) For diesel vehicles, do not use
gasoline. See “ Fuel for Diesel
Engines ” in the Duramax diesel
supplement. E85 or FlexFuel FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 272 .
Engine Oil Life System The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
To reset the engine oil life system:
1. Display the oil life percentage
on the DIC. See Driver Information Center
(DIC) (Midlevel and Uplevel)
0 160 or Driver Information
Center (DIC) (Base Level)
0 159 .
2. Press the thumbwheel on the
steering wheel, or the trip
odometer reset stem if the
vehicle does not have DIC
controls, for several seconds.
When the confirmation
message displays, select YES.
The oil life will change
to 100%.
The oil life system can also be reset
as follows:
1. Display the oil life percentage
on the DIC.
See Driver Information Center
(DIC) (Midlevel and Uplevel)
0 160 or Driver Information
Center (DIC) (Base Level)
0 159 .
2. Fully press the accelerator
pedal slowly three times within
five seconds.
3. If the display changes to 100%,
the system is reset.

144 Instruments and Controls Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
.
It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.
The gauge moves a little while
turning a corner or speeding up.
.
The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off. Engine Oil Pressure
Gauge
Uplevel Metric Shown, Base Level
and Midlevel Similar Uplevel English Shown, Base
Level and Midlevel Similar
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, coolant
temperature, and oil viscosity.
On some models, the oil pump will
vary engine oil pressure according
to engine needs. Oil pressure may
change quickly as the engine speed
or load varies. This is normal. If the
oil pressure warning light or Driver

Instruments and Controls 145Information Center (DIC) message
indicates oil pressure outside the
normal operating range, check the
vehicle's oil as soon as possible.
See Engine Oil 0 321 .
CautionLack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine,
see the Duramax diesel
supplement. Engine Coolant
Temperature Gauge
Uplevel Metric Shown, Base Level
and Midlevel Similar Uplevel English Shown, Base
Level and Midlevel Similar
This gauge measures the
temperature of the vehicle's engine
coolant.
While driving under normal
operating conditions, if the needle
moves into the red warning area,
the engine is too hot. Pull off the
road, stop the vehicle, and turn off
the engine as soon as possible.

Engine Oil Pressure Light
(Uplevel Cluster) CautionLack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil. This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced
by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
Low Fuel Warning Light
This light is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working.
It also comes on when the fuel tank
is low on fuel. The light turns off
when fuel is added. If it does not,
have the vehicle serviced. Security Light The security light should come on
briefly as the engine is started. If it
does not come on, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light turns off.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system. See Immobilizer Operation

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.
Trip 1 or 2 and Average Fuel
Economy
Turn the trip odometer reset stem
until TRIP 1 or TRIP 2 displays. The
current distance traveled, in either
kilometers (km) or miles (mi), since
the last reset for the trip odometer is
shown, as well as the average fuel
economy. The trip odometer and the
average fuel economy can be reset
by pressing and holding the trip
odometer reset stem.
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.
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
0 369 and Tire Pressure Monitor
Operation 0 370 .
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 0 321 .
In addition to the engine oil life
system monitoring the oil life,

recommended. See Maintenance
Schedule 0 415 .
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 0 323 .
Air Filter Life
Turn the trip odometer reset stem
until AIR FILTER LIFE displays.
This displays an estimate of the
engine air filter ’ s remaining useful
life and the state of the system.
Engine Air Filter Life 95% means
95% of the current air filter life
remains. Messages will display
based on the engine air filter life and
the state of the system.
When the REPLACE AT NEXT OIL
CHANGE message displays, the
engine air filter should be replaced
at the time of the next oil change.
When the REPLACE NOW message displays, the engine air
filter should be replaced as soon as
possible.
The Air Filter Life display must be
reset after the engine air filter
replacement. To reset, see Engine
Air Filter Life System 0 325 .
Brake Pad Life
This displays an estimate of the
remaining life of the front and rear
brake pads. Messages will display
based on brake pad wear and the
state of the system. Reset the Brake
Pad Life display after replacing the
brake pads. See Brake Pad Life
System 0 335 .
