2. Safety Information

Read and understand all instructions before installing and using the Thule Interstate Cargo Bag. Failure to follow these instructions can result in property damage, personal injury, or voiding of the product warranty.

• Weight Limits: Do not exceed the maximum weight capacity of your vehicle's roof rack system or the cargo bag itself. Refer to your vehicle's owner's manual for roof load limits.
• Secure Attachment: Always ensure the cargo bag is securely attached to your roof rack using all provided straps. Check strap tension before each trip and periodically during long journeys.
• Load Distribution: Distribute cargo evenly inside the bag. Place heavier items at the bottom and center of the bag to maintain vehicle stability.
• Clearance: Be aware of the increased height of your vehicle with the cargo bag installed, especially when entering garages, car washes, or low-clearance areas.
• Driving Habits: Adjust your driving speed and habits to account for the added weight and wind resistance. Avoid sudden maneuvers, hard braking, or high speeds.
• Inspection: Regularly inspect the cargo bag and attachment straps for signs of wear, damage, or loosening. Do not use if damaged.
• Sharp Objects: Avoid placing sharp or abrasive objects directly against the bag's interior without adequate padding to prevent tears.

4. Setup & Installation

The Thule Interstate Cargo Bag is designed for easy installation on vehicles equipped with a roof rack system.

4.1 Preparing the Bag

1. Unpack the cargo bag from its stuff sack.
2. Unfold the bag and lay it flat on a clean, dry surface.
3. Ensure the zipper is fully closed before placing it on the vehicle.

4.2 Attaching to Vehicle Roof Rack

The bag is compatible with Thule rack systems, round bars, and most factory racks.

1. Carefully place the empty cargo bag onto your vehicle's roof rack, centering it as much as possible. Ensure the padded base is facing down to protect your vehicle's finish.
2. Locate the heavy-duty, double-stitched webbing straps on the cargo bag. These straps are designed to loop around your roof rack crossbars or side rails.
3. Thread each strap securely around the crossbar or side rail and fasten it according to the strap's buckle mechanism. Ensure the straps are not twisted.
4. Tighten all straps firmly to eliminate slack. The bag should be snug against the roof rack and not shift when pushed.
5. Double-check all attachment points to ensure they are secure before loading the bag.

5. Operation

5.1 Loading the Cargo Bag

1. Unzip the three-sided zipper to open the bag. The large storm flaps will help keep the interior dry during loading, even in light rain.
2. Place items inside the bag, distributing weight evenly. Place heavier items towards the center and bottom.
3. Avoid overfilling the bag. Ensure the zipper can close easily without excessive strain.
4. For optimal weather resistance, consider placing sensitive items in additional waterproof bags or containers inside the cargo bag.

5.2 Securing Cargo

1. Once loaded, close the three-sided zipper completely. Ensure the storm flap covers the zipper entirely.
2. Tighten the twin compression straps located on the bag. These straps help to compress the cargo, reduce shifting, and maintain the bag's aerodynamic shape, even in wind.
3. Re-check all roof rack attachment straps to ensure they are still tight and secure after loading.

6. Maintenance & Storage

6.1 Cleaning

• Clean the cargo bag with mild soap and water. Do not use harsh chemicals or abrasive cleaners, as these can damage the material and weather-resistant coating.
• Rinse thoroughly and allow the bag to air dry completely before storing.
• Clean the zippers periodically to ensure smooth operation.

6.2 Inspection

• Before each use, inspect the bag for any tears, punctures, or damage to the fabric, seams, zippers, and straps.
• Check the integrity of the attachment straps and buckles. Replace any damaged components immediately.

6.3 Storage

• When not in use, ensure the bag is clean and completely dry.
• Fold the bag neatly and place it into its included stuff sack.
• Store the bag in a cool, dry place away from direct sunlight and extreme temperatures to prolong its lifespan.

7. Troubleshooting

7.1 Water Leakage

• Issue: Water is entering the cargo bag during rain.
• Solution: Ensure the three-sided zipper is fully closed and the storm flap completely covers the zipper. While the bag is weather-resistant, it is not fully submersible. For maximum protection of sensitive items, use additional waterproof bags inside the carrier. Inspect for any tears or punctures in the fabric.

7.2 Bag Shifting or Loose

• Issue: The cargo bag moves or feels loose on the roof rack.
• Solution: Re-tighten all webbing straps securely. Ensure they are correctly routed around the crossbars or side rails and not twisted. Distribute cargo evenly to prevent imbalance. Check strap tension periodically during travel.

7.3 Difficulty Closing Zipper

• Issue: The zipper is difficult to close or gets stuck.
• Solution: Avoid overfilling the bag. Ensure no fabric or cargo is caught in the zipper teeth. Clean the zipper teeth if dirt or debris is present. A small amount of zipper lubricant can also help.
