Low Oil Level Message - False Display

Bulletin 91-6D-2

Date Dec. '90

Ref. No. 91-073-6D

Corp. Ref. No. 018317


SUBJECT: LOW OIL LEVEL MESSAGE - NORMAL OPERATION


MODELS AFFECTED: 1988 - 91 RIVIERA MODELS


Some 1988-1991 Rivieras that have been parked at an angle (i.e., on a hill or two wheels in a ditch) either front to back or side to side may exhibit a false low oil message. The angle of the vehicle causes the oil in the oil pan to flow away from the oil level switch. This condition is normal and will not be corrected by replacing the oil level switch or oil pan.
