3 TERM.(UA8) BATTERY SYSTEM CONVERT TO COMMON BATTERY SYS.

VEHICLES AFFECTED: 1985 Electras Equipped With Option UA8 --------------------------------------

Buick Motor Division has discontinued the optional Power Reserve Battery System which was available on 1985 Electras. Due to the limited number of vehicles produced with this system, and to the possibility of customer inconvenience in obtaining service on this system, the following Special Policy has been established.

Vehicles produced with the Power Reserve System option UA8 will be converted to a more common battery system. This consists of replacing the three (3) terminal posi-power battery with a new two-terminal heavy duty UA1 option 78A72 battery and replacing the power reserve controller and battery cables with new battery cables.

Owners of vehicles involved will be refunded the list price difference of $134.45 between the price of the two options, plus any applicable Provincial tax.

This Special Policy conversion will be done at no charge to the owner regardless of the vehicle age or mileage until August 31, 1986. After August 31, 1986, GM of Canada will continue the refund offer and the conversion of the power reserve system regardless of age or distance of vehicle at no charge, but the cost of the replacement or new battery will be at the customer's expense.

A copy of this 'Special Policy Bulletin,' should be filed in the 3-ring binder furnished to the Dealer by General Motors in September 1982.

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.
