Affected Component: EQUIPMENT

Summary
Dealer Letter: Toyota will initiate a Special Service Campaign to inform certain Tercel owners of the need to use only Koito brand replacement headlamp bulbs. The original equipment headlamp bulbs in these vehicles were all Koito brand. The use of any brand of bulb other than Koito can cause the headlamp to fail to meet all of the photometric requirements of the Federal Motor Vehicle Standard No. 108. Owners will be supplied with caution labels and asked to install them on the headlamp housings. Owners who have previously replaced headlamp bulbs will be asked to bring their vehicle to a dealer for inspection and, if necessary, replacement with a Koito brand bulb. Any headlamp bulb of the involved vehicles that is burnt out now or in the future will be replaced free of charge with a Koito brand bulb. Please assist any involved Tercel owner by inspecting and replacing any non-Koito or burned out headlamp bulb with the correct Koito bulb. If an owner has not installed the caution labels on each headlamp housing, please do so for them. An initial supply of these labels is enclosed with this information package. Should you require additional labels, they can be ordered by calling (310) 783-5596. In addition, please install caution labels and Koito headlamp bulbs as necessary in any vehicles currently in your stock.
