NOTICE: When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may be used. Fasteners that are not reused, and those requiring thread locking compound will be called out. The correct torque value must be used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.

FOLDING TOP OPERATION
The folding top is manually operated. When the folding top is raised, it attaches to the windshield header in the front and to the tonneau panel in the rear. When the folding top is lowered, it is stored in a top well behind the rear seat. The top well is covered by the tonneau panel.
Lowering Top
CAUTION:
The vehicle must be parked on a level surface with the trunk lid closed before lowering or raising the folding top or tonneau, or damage to the folding top or tonneau and possible personal injury could result.
1. Set the parking brake.
2. Shift the automatic transmission to "P" (park) or the manual trans- mission to "NEUTRAL."
3. Turn the ignition to "RUN" position.
4. Lower the side windows. If battery is discharged and windows won't lower, open the doors.

6. Raise the number five bow to its vertical position.
7. Push the tonneau panel release switch rearward to release the tonneau panel.
8. Raise the tonneau panel to its vertical position.
9. Lower the number five bow.
NOTICE: Before lowering the folding top, make sure nothing is in the top well, or damage to the folding top and bows could result.
10. Pull each latching handle down and rotate each latch handle outboard to release the folding top from the windshield header.
11. Grasp the front edge of the number one bow; lift upward and rearward.
NOTICE: Avoid jamming the folding top bows against one another or damage to the folding top and bows could result.
12. Slowly bring the folding top rearward until it is all the way down and return the top latch handles to the closed and stowed position.
13. Lower and latch the tonneau panel.
14. Make sure the tonneau panel is latched securely by gently lifting up on both forward ends of the tonneau panel.
NOTICE: Do not sit or place excessive weight on the tonneau panel when the folding top is down, or damage to the tonneau panel could result.
Raising Top
CAUTION:
The vehicle must be parked on a level surface with the deck lid closed before lowering or raising the folding top or tonneau, or damage to the folding top or tonneau and possible personal injury could result.
1. Set the parking brake firmly.
2. Shift the automatic transmission to "P" (park) or the manual trans- mission to "NEUTRAL."
3. Turn the ignition to "RUN" position.
4. Lower the side windows. If battery is discharged and windows won't lower, open the doors.
5. Push the tonneau panel release switch rearward to release the tonneau panel.
6. Raise the tonneau panel to its vertical position.
NOTICE: Do not sit or place excessive weight on the folding top when it is up, or damage to the folding top could result.

8. Continue to raise the folding top until it is against the windshield header.
9. Press downward until the guide pins drop into the windshield header.
10. While holding the folding top in place, rotate each latch handle for- ward, securing the folding top to the windshield header and push each handle up to its stowed position.
11. Raise the number five bow to its vertical position.
12. Lower and latch the tonneau panel.
13. Make sure the tonneau panel is latched securely by firmly but gently lifting up on both forward ends of the tonneau panel.
14. Lower the number five bow and align the pin on number five bow into the hole in the tonneau panel. Push downward until pin engages into latch.
ADJUSTMENTS
The folding top linkage includes the number one bow, side roof rails, hinges, connecting links and bows. The top linkage is attached to the body at the rear quarter area by a stationary main pivot bracket. The folding top locks to the windshield header with latches. When the folding top framework does not work correctly, the problem is usually a damaged or misaligned linkage.
For the folding top to work properly, all the folding top parts must be aligned accurately. If damage has occurred. forcing the pivot points out of alignment, it will be difficult to reset the links to the correct dimen- sions by visually realigning them. If the alignment can- not be corrected, the entire subassembly where the affected linkage is, must be replaced. If a pivot bolt or link is broken, it must be replaced.

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.
