Bulletin: 88-8-23

Date: Oct. '88

Ref. No.: 88-219-8

Corp. Ref. No.: 808305
SUBJECT: FUEL GAGE DISPLAY (EXPLANATION) WITH UB3 INSTRUMENT CLUSTER

MODELS AFFECTED: 1988 REGAL

CONDITION

Customers may comment that the 1/4 tank expansion mode fuel display malfunctions.



CAUSE

The spacing between the indicator segments is greater on the 1/4 tank expansion mode display than on the normal mode full tank display (See Illustration). Also, customers do not always distinguish between the small, lower reference segments and the large, upper indicator segments. They may think segments are burned out or that the gage is inoperative.
EXPLANATION

The 1/4 tank display is made up of five small, lower reference segments and five large, upper indicator segments. As fuel is consumed, the upper segments blank out but the lower reference segments do not. The triangular, orange warning light illuminates when the fourth indicator segment in the expansion mode turns off.
