BUICK LACROSSE 2005 Owner's Manual

Driver Information Center (DIC)
Your vehicle may have a Driver Information
Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the speedometer.
The DIC buttons are located on the center of the
instrument panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the DIC on the uplevel vehicle will display the
WELCOME DRIVER (1 or 2) if a personalized key 1 or 2
is used, and then the information that was last
displayed before the engine was turned off.
The DIC on the base level vehicle displays the odometer
and trip odometers only.
The DIC on the uplevel vehicle displays the odometer,
trip odometers, fuel economy, trip computer, vehicle
system, and compass display information. It also
displays warning messages if a system problem is
detected. In addition, the DIC on the uplevel vehicle
displays phone numbers that are called using the
OnStar
®system, if equipped. SeeOnStar®System on
page 2-34.The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air
temperature is at or below 37°F (3°C), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there
is a problem with the system that controls the
temperature display, the letters OC (open circuit) or SC
(short circuit) will appear on the display. If this occurs,
have the vehicle serviced by your GM dealer.
The DIC on the uplevel vehicle also allows some
features to be customized or personalized. SeeDIC
Vehicle Personalization on page 3-71for more
information.

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays.
This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode 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.
Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on
page 3-53for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY displays.
This mode 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 AVG ECONOMY, press and hold the
set/reset button. The display will return to zero.
Instantaneous Fuel Economy
Press the fuel button until INST ECONOMY displays.
This mode shows the current fuel economy at a
particular moment and will change frequently as driving

Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC. This
is normal.
Oil Life
Press the gages button until OIL LIFE displays. This
mode shows an estimate of the oil’s remaining useful
life. If you see OIL LIFE 99% on the display, that means
99% of the current oil life remains. The engine oil life
system will alert you to change your oil on a schedule
consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change your oil as soon as possible. SeeEngine Oil
on page 5-15. 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 6-4for
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, press and hold the

on page 3-71for additional information on personal
programming.
Compass Zone
Under certain circumstances, such as during a long
distance cross-country trip, it will be necessary to
compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between the earth’s
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
in the vehicle could give false readings.
In order to do this, the compass must be set or
calibrated to the variance zone in which the vehicle
is travelling.To adjust for compass variance, use the following
procedure:
Compass Variance Procedure
1. Press the option button until COMPASS ZONE
displays.
2. Find the vehicle’s current location and variance
zone number on the map.
Zones 1 through 15 are available.
3-52

3. Press the set/reset button to scroll through and
select the appropriate variance zone.
The direction the vehicle is moving will be displayed
in the top right corner of the DIC display.
4. If you need to calibrate the compass, use the
compass calibration procedure. See “Compass
Calibration Procedure” following.
Compass Calibration
The compass is manually calibrated. Only calibrate the
compass in a safe location where driving the vehicle
in circles is not a problem.
To calibrate the compass, use the following procedure:
Compass Calibration Procedure
1. Press the option button until the COMPASS
CALIBRATION screen is displayed.
2. Press the set/reset button to start the compass
calibration.
3. The DIC will display CALIBRATION BEGUN DRIVE
IN CIRCLES. Drive the vehicle in a circle until the
DIC displays CALIBRATION FINISHED. The
DIC will display CALIBRATION FINISHED for
several seconds and then will display the
COMPASS CALIBRATION screen.
DIC Warnings and Messages
Messages are displayed on the uplevel DIC to notify the
