# ELECTRONIC INSTRUMENT PANEL CLUSTER INFORMATION

#### VEHICLES AFFECTED: 1985 Cutlass Ciera

Some late production 1985 Cutlass Ciera models equipped with the electronic instrument panel cluster (U52) may have a 'Service Engine Soon' light instead of a 'Check Engine' light. This will then carry over into the electronic instrument panel cluster for the 1986 model year Cutlass Ciera.

In addition, some service replacements may have a 'Service Engine Soon' light instead of a 'Check Engine' light.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
