SERVICE MANUAL UPDATE - SECTION 8B

This service bulletin cancels and supersedes all Glove Box Literature regarding Headlamp Aiming on the 1991 Century.

The headlamp aim on the vehicle covered in this bulletin has been certified to be within the manufacturer's specification at the assembly plant with an "Electronic Headlamp Beam Aim System". These headlamps will not require any readjustment at the time of dealer, delivery or during Pre-Delivery Inspection (P.D.I.).

If there is a concern expressed by a customer about headlamp aim, the preferred method to check or correct aim is by the visual aiming equipment or screen aiming method as identified in this bulletin.

If headlamps cannot be aimed by the screen aiming method or visual aiming equipment, use the (optional) mechanical headlamp aiming method described in this bulletin.
