MODE: Press this button to cycle through three
modes of operation
-- Off, Compass/Temperature
and Trip Computer mode.
In the Trip Computer mode, pressing the MODE
button cycles through the five displays. Press the
MODE button after the last Trip Computer display to
return the DIC to the OFF mode.
Off: No driver information is displayed in this mode
of operation.
Compass/Temperature Mode: One of eight compass
readings and the outside temperature are displayed. If
the temperature is below 38F (3C), the temperature
reading will toggle between displaying the outside
temperature and the word ªICEº for two minutes.
Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass variance must be set.Setting the VarianceTurn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for approximately
five seconds. The last entered variance zone number will
be displayed. Press the E/M button until the proper
variance number, as shown on the map, is showing.
Press the MODE button to set the new variance zone
and resume normal operation.
The display will show all the display segments briefly to
acknowledge the change in the zone number.

Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases the calibration symbol C will be displayed
where the compass reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make three 360 turns. The calibration
symbol will turn off and the compass reading will
be displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for at least 10 seconds
until the calibration symbol appears. Release both
buttons and complete three 360 turns in an area free
from large metal objects. The calibration symbol will
turn off and the compass reading will be displayed.Error Displays
An error of the vehicle's speed sensor or fuel sender
will cause
-E- to be displayed.
In the absence of vehicle communications, a
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.
Trip Computer
There are five trip computer displays which may be
stepped through by pressing the MODE button. The
information will appear in the following order:
AVG ECON (Average Fuel Economy): This shows
the average fuel economy since the last reset.
INST ECON (Instantaneous Fuel Economy): This
shows fuel economy for the most recent second
of driving.
RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving.
FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.
AVG SPEED (Average Speed): This shows the
average speed since the last reset.

Resetting the Trip Computer
Press and hold the MODE and E/M buttons for at least
two seconds. The reset is acknowledged with the display
showing all segments on briefly. A reset can only be
done in AVG ECON, FUEL USED and AVG SPEED
displays. AVG ECON, FUEL USED and AVG SPEED
can be reset independently. Only the mode that is
displayed will be reset.
Rear Parking Assist (Option)
Rear parking assist can help you to determine how close
an object is to your rear bumper within a given area,
making parking easier. It is not intended to be used
primarily as a rear obstacle detection system.
The rear parking assist display is located inside the
vehicle, above the rear window. It has three color
-coded
lights that can be seen through the rearview mirror.
The rear PARK AID switch
is located in the overhead
console switchbank.
Rear parking assist can be disabled by pressing the
part of the switch with the PARK AID disable symbol
on it. Pressing the textured part of the switch enables
the system.

6-16 When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A change engine oil message will come on.
Change your oil as soon as possible within the next
two times you stop for fuel. It is possible that, if you
are driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for
over a year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset. It is also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.How to Reset the Change Engine Oil Message
The GM Oil Life System calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to a change
engine oil message being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL is
displayed on the Driver Information Center.
2. When OIL is displayed, push and hold the
trip/reset button for five seconds. The number will
disappear and be replaced by 100 (indicating 100%
oil life remaining).
3. Turn the key to OFF.
If the change engine oil message comes back on,
the engine oil life monitor has not reset. Repeat
the procedure.
