2009 CHEVROLET IMPALA warning

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the right of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the shift
lever position indicator. SeeAutomatic Transmission
Operation on page 2-24for more information.
If your vehicle has these features, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. The compass
direction appears on the top right corner of the DIC
display. The outside air temperature automatically
appears in the bottom right corner of the DIC display.
If there is a problem with the system that controls the
temperature display, the numbers will be replaced with
dashes. If this occurs, have the vehicle serviced by your
dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 3-57for
more information.
DIC Operation and Displays
The DIC has different displays which can be accessed
by pressing the DIC buttons located on the instrument
panel, to the right of the instrument panel cluster.
DIC Buttons
The buttons are
the trip/fuel, vehicle
information, customization,
and set/reset buttons.
The button functions are
detailed in the following
pages.
3(Trip/Fuel):Press this button to display the
odometer, trip odometers, fuel range, average economy,
instantaneous economy, Active Fuel Management™
indicator on vehicles with this feature, and average
speed.
3-42

If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the display
will show the number of miles (mi) or kilometers (km) that
were driven during the last ignition cycle.
Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of remaining
miles (mi) or kilometers (km) 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. This estimate
will change if driving conditions change. For example, if
driving in traffic and making frequent stops, this display
may read one number, but if the vehicle is driven on a
freeway, the number may change even though the same
amount of fuel is in the fuel tank. This is because different
driving conditions produce different fuel economies.
Generally, freeway driving produces better fuel economy
than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message displays. See “FUEL LEVEL LOW” under
DIC Warnings and Messages on page 3-49for more
information.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of
mpg (L/100 km) recorded since the last time this menu
item was reset. To reset this display to zero, press and
hold the set/reset button.
Instantaneous Economy and Active Fuel
Management™ Indicator
Press the trip/fuel button until INST ECONOMY displays.
If your vehicle has the Active Fuel Management™
feature, INST ECONOMY 8CYL MODE will display
on vehicles with a V8 engine. This display shows the
current fuel economy at a particular moment and
will change frequently as driving conditions change.
This display shows the instantaneous fuel economy
in miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). Unlike average economy, this screen
cannot be reset.
3-44

If your vehicle has the Active Fuel Management™
feature, an Active Fuel Management™ indicator
will display on the right side of the DIC, while
INST ECONOMY displays on the left side. Active
Fuel Management™ allows the engine to operate
on either all or half of its cylinders, depending on
your driving demands.
For vehicles with a V8 engine, when Active Fuel
Management™ is active, 4CYL MODE will display.
When Active Fuel Management™ is inactive,
8CYL MODE will display.
SeeActive Fuel Management™ (5.3L V8 Engine) on
page 2-23for more information.
Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display shows the average speed of the
vehicle in miles per hour (mph) or kilometers per hour
(km/h). This average is calculated based on the various
vehicle speeds recorded since the last reset of this value.
To reset the value, press and hold the set/reset button.
The display will return to zero.
Blank Display
This display shows no information.
Vehicle Information Menu Items
T
(Vehicle Information):Press this button to scroll
through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an estimate of
the oil’s remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system will alert
you to change the oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON” under
DIC Warnings and Messages on page 3-49. You should
change the oil as soon as possible. SeeEngine Oil on
page 5-17. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
3-45

Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally 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, seeEngine Oil
