Information Displays
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 on page 9‑20 for 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.
The DIC also allows some features
to be customized. See
Vehicle
Personalization on page 5‑33 for
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.

Black plate (24,1)Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12
5-24 Instruments and Controls
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. SeeFuel System
Messages on page 5‑29 for 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
Press the trip/fuel button until INST
ECONOMY displays. 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.
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 recordedsince the last reset of this value. To
reset the value, press and hold the
set/reset button. The display will
return to zero.

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.

Instruments and Controls 5-25
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
SeeEngine Oil Messages on
page 5‑28. You should change the
oil as soon as possible. See Engine
Oil on page 10‑6. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11‑3 for more information.
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, see Engine
Oil Life System on page 10‑8.

Tire Pressure
On vehicles with the Tire Pressure
Monitor System (TPMS), the
pressure for each tire can be viewed
in the DIC. The tire pressure will be
shown in either pounds per square
inch (psi) or kilopascals (kPa). Press
the vehicle information button until
the DIC displays FRONT TIRES
PSI (kPa) LEFT ## RIGHT ##. Press
the vehicle information button again
until the DIC displays REAR TIRES

If a low tire pressure condition is
detected by the system while
driving, a message advising you to
add air to a specific tire will appear
in the display. See
Tire Pressure on
