Pressing any one of the DIC buttons will reset or remove
any active status messages from the display. Personalization messages supersede
status messages.
For cellular telephone messages (if equipped), the cellular telephone
status is displayed by the instrument cluster as listed below, where ### indicates
the cellular telephone received signal strength:
| • | CEL-PHONE ### INCOMING CALL |
| • | CEL-PHONE SYSTEM NO SERVICE |
| • | CEL-PHONE ### CALL TIMER XX:YY |
The instrument cluster may also display phone numbers stored in the
cellular telephone's memory with associated alpha-tags and digit dialing.
Cellular telephone displays, when active, cannot be reset or removed from
the display. Warning/Status messages may supersede cellular telephone displays
if they exist.
For personalization status messages, use the driver information center
in order to allow the driver to customize various vehicle features through
the personalization displays. Personalization messages display in a predetermined
order. Initial messages will provide instructions on how to use the system,
followed by the actual customize selection messages. A list of messages follows:
| • | WELCOME TO BUICK OPTION FEATURE DRIVER # |
| • | ARMREST BUTTON CHANGES DRIVER # |
| • | PRESS ENG/MET TO SELECT OPTION |
| • | PRESS RESET TO GO TO NEXT CHOICE |
| • | LOCK FEEDBACK LIGHTS LIGHTS+HORN |
| • | UNLOCK FEEDBACK OFF LIGHTS |
| • | PERIMETER LIGHTING OFF ON |
| • | RECALL POSITION MEMORY EXIT |
| • | OPTION FEATURE SELECTION DONE |
Pressing either the ODO/TRIP, FUEL INFO or GAGE buttons may remove personalization
messages from the display , when active. Driver identifier messages supersede
personalization displays if they exist.
For the driver identifier messages, the DIC may be used in order to
indicate the current driver # of the vehicle. This information is displayed
at each ignition cycle and is part of the vehicle personalization functions.
You may program actual customer names into the instrument cluster in order
to appear in the driver # display for added convenience. A complete list
of messages and analysis is provided in the diagnostic portion of this
section. An export ID# will accompany the driver identifier messages for
non-US vehicles. The DIC may display the following messages:
You cannot remove active driver identifier messages from the display.
Other messages cannot supersede driver identifier displays.
Pressing one of the IP buttons next to the instrument cluster
commands the instrument cluster to perform the following functions:
ENG/MET: The ENG/MET button toggles the instrument cluster and the heater
and A/C module between the English/metric unit modes. The instrument cluster
sends the current selected unit mode status to the heater and A/C module,
through the class 2 serial data line. The instrument cluster also
sends the current selected mode status to the HUD (optional) through
the serial parallel interface (SPI).
ODO/TRIP: The ODO/TRIP button displays the following odometer information:
| • | Season odometer/trip odometer #1 (TRIP 1:) |
| • | Season odometer/trip odometer #2 (TRIP 2:) |
The FUEL INFO button scrolls the DIC through the following fuel
information messages.
| • | For the FUEL ECONOMY AVERAGE (MPG or L/100km) XXX, the Average
Fuel Economy (AFE) is computed by using the following formula: AFE= (Trip
Distance) / (Trip Fuel Used) x Scale Factor. The AFE value is reset when
the FUEL ECONOMY AVERAGE message displays when you press the RESET button. |
| | The trip distance value is the distance traveled. The trip fuel used
value is fuel used since the last reset. The trip fuel used data is received
from the PCM. The trip distance is determined from the vehicle speed
input. |
| • | For the FUEL ECONOMY INST (MPG or L/100km), the Instantaneous
Fuel Economy (IFE) is based on the previous few seconds of driving and is
computed by using the following formula: IFE = Distance / Fuel Used
x Scale Factor. |
| | Distance is determined from the discrete vehicle speed input to the
instrument cluster. Since the fuel data is received from the PCM, this portion
of the instrument cluster is dashed if the instrument cluster loses communication
with the PCM. |
| • | The vehicle (fuel) range displays as an estimate of expected remaining
driving distance with the current fuel level. Driving range is based on
the fuel in the tank and fuel economy of the last 25 miles. Because
of the required predictions, the displayed range and the actual range
may vary. When the calculated range falls below 40 miles, the
range displays LOW. Vehicle range is calculated by the instrument cluster
using the following formula: Estimated Drivable Range = Distance Traveled/Fuel
Used x Scale Factor x Filtered Fuel in Tank. |
| | The calculation cannot be reset by the driver. The data used in order
to calculate the range is lost if the battery is disconnected. This portion
of the instrument cluster is dashed if the instrument cluster loses
communication with the PCM. |
| • | The Fuel Used is the gallons (L) used since the last reset. The
fuel used is reset by pressing the RESET button when the fuel used is displayed
on the DIC. Incremental fuel used data is received from the PCM and
stored in the instrument cluster. This portion of the instrument cluster
is dashed if the instrument cluster loses communication with the PCM. |
The GAUGE button scrolls the DIC through the following messages:
| • | For OIL PRESSURE NORMAL (psi or kPa), the oil pressure data is
received from the PCM through the class 2 serial data line. The word
NORMAL is replaced with LOW when the low oil pressure indicator is activated.
This portion of the instrument cluster displays ???? if the instrument
cluster loses communication with the PCM. |
| • | For COOLANT TEMP NORMAL (°F or °C), the coolant temperature
data is received from the PCM through the class 2 serial data line.
The word NORMAL is replaced with HOT when the coolant temperature indicator
is activated. This portion of the instrument cluster displays ????
if the instrument cluster loses communication with the PCM. |
| • | For BATTERY STATE NORMAL V, the battery voltage data is received
from the SBM through the class 2 serial data line. The word NORMAL
is replaced with LOW when the battery voltage is less than 10.5 volts
and with HIGH when the battery voltage is greater than 15.9 volts.
This portion of the instrument cluster displays ???? if the instrument
cluster loses communication with the SBM. |
| • | For OIL LIFE INDEX NORMAL ###%, ### represents the approximate
percentage of useful oil life remaining. The word NORMAL is replaced with
CHANGE OIL when the oil life index is less than 11%. This portion of
the instrument cluster displays ???? if the instrument cluster loses communication
with the SBM. After an oil change, reset the message by displaying the
OIL LIFE INDEX NORMAL ###% message and then pressing the RESET button
for approximately 5 seconds or until the OIL LIFE INDEX NORMAL
100% message displays. |
| • | For TIRE PRESSURE NORMAL, the tire pressure status is calculated
by the EBTCM and sent to the instrument cluster through the class 2
serial data line. The word NORMAL is replaced with LOW : CHECK TIRES when
a low tire pressure condition is detected. This portion of the instrument
cluster will display ???? if the instrument cluster loses communication
with the EBTCM. To reset, fill the tires to the proper pressures, then
display the TIRE PRESSURE LOW: CHECK TIRES message and press the RESET button
for approximately 5 seconds or until the TIRE PRESSURE NORMAL
message displays. |
