• Wear appropriate personal protective equipment, including gloves and eye protection.

3. Setup and Installation

The Sierra Auto Tops Convertible Top is designed for a precision fit on Mazda Miata MX5 models from 1990-2005. While some experienced individuals may perform the installation themselves, professional installation is recommended due to the complexity and precision required.

3.1 Pre-Installation Considerations

• Review Instructions: Thoroughly read all instructions and watch any available installation videos before beginning.
• Tools Required: Gather all necessary tools, including rivet guns, drills, screwdrivers, wrenches, and possibly a heat gun.
• Working Conditions: Install the top in a warm environment (ideally above 70°F / 21°C) to allow the vinyl material to be more pliable. If installing in colder temperatures, allow the top to warm up indoors for several hours.
• New Cables: It is highly recommended to replace the convertible top cables during installation for optimal function and longevity.
• Rain Rail: This model includes a factory-installed rain rail. Inspect the existing rain rail for cracks or damage. If damaged, repair or replace it as necessary.

3.2 General Installation Steps (Summary)

This is a general overview. Detailed steps will vary and should be followed from a comprehensive guide or professional installer.

1. Remove Old Top: Carefully remove the existing convertible top, noting the placement of all fasteners, rivets, and seals. Take photos for reference.
2. Prepare Frame: Clean and inspect the convertible top frame for any damage or corrosion. Repair as needed.
3. Install New Top: Position the new Sierra Auto Tops convertible top onto the frame. This often requires careful alignment and stretching.
4. Secure Fasteners: Attach the top to the frame using rivets, screws, and other fasteners as specified. Ensure all mounting holes align correctly.
5. Install Seals and Cables: Reinstall or replace weather seals and tension cables.
6. Initial Closure: The new top will be very tight. It may require significant effort to close the first few times. Do not force it excessively. Allow the material to stretch and relax over a few days, especially in warm conditions. Adjust latches as needed for initial closure, then gradually return them to their original settings as the top settles.

4. Operation

Operating your new convertible top is similar to the original. Ensure the vehicle is stationary before attempting to raise or lower the top.

• Latching/Unlatching: Use the vehicle's original latch mechanisms to secure or release the front of the top to the windshield frame.
• Folding: When lowering the top, ensure it folds smoothly into its designated storage area without pinching or creasing the vinyl.
• Raising: When raising the top, ensure it extends fully and latches securely before driving.

5. Maintenance and Care

Proper care will extend the life and appearance of your convertible top.

• Cleaning: Clean the vinyl top regularly with mild automotive soap and water. Avoid harsh chemicals or abrasive cleaners that can damage the material. Rinse thoroughly.
• UV Protection: The Cabrio vinyl material is UV-resistant, but applying a vinyl protectant designed for convertible tops can further enhance its longevity and prevent fading.
• Window Care: The plastic rear window should be cleaned with a soft cloth and a plastic-safe cleaner. Avoid wiping it when dry to prevent scratches.
• Storage: When the top is down, ensure it is properly folded and secured to prevent damage from wind or debris. If storing the vehicle for extended periods, keep the top up to maintain its shape.
• Inspection: Periodically inspect the top for any signs of wear, tears, or seam separation. Address minor issues promptly to prevent them from worsening.

6. Troubleshooting

• Top is too tight after installation: This is normal. The vinyl material needs time to stretch and conform. Park the car in the sun with the top closed for several days. Gradually adjust the latches as the material relaxes. Avoid excessive force.
• Water leaks: Check all seals around the windows and the rain rail. Ensure the rain rail is properly seated and free of cracks. Verify that the top is fully latched and adjusted correctly.
• Difficulty latching: Ensure the top is fully extended and aligned with the windshield frame. If the top is new, it may be tight; allow time for stretching. Adjust the latch mechanisms if necessary.
• Seam separation: While the product is designed for durability, inspect seams periodically. If separation occurs within the warranty period, contact customer support.
