Thule cargo boxes are durable and strong enough to protect your cargo from the elements. Cargo boxes store equipment and luggage, leaving the interior of your vehicle free for passengers. Available in a range of models, Thule cargo boxes feature a lock so that your cargo is safe when you're not around and an easy-snap system that makes them simple to install on your vehicle's roof rack system.

  1. 1

    Set the roof rack system (if it is adjustable) on your vehicle to the widest position that will fit the mounting holes in the cargo box. The minimum width that the Thule cargo box will accommodate is 23-5/8 inches.

  2. 2

    Lift the cargo box onto the roof rack. You may need someone to help you do this.

  3. 3

    Slide the box forward or backward to position the mounting holes located on the bottom of the box properly over the crossbars of your roof rack. Mount your cargo box toward the rear of the vehicle to minimise wind resistance.

  4. 4

    Open the cargo box and remove the bag of hardware inside.

  5. 5

    Remove the easy-snap mounting hardware and attach the rectangular rubber pads onto the bottom of each of the four easy-snap brackets.

  6. 6

    Lift the red safety tab on top of the easy-snap bracket then twist the blue handle counterclockwise. Do this for each bracket.

  7. 7

    Insert the easy-snap brackets into the appropriate holes on your cargo box support bars. Line up the load bar with the red safety tab lever toward the rear of the cargo box.

  8. 8

    Slide each of the four U-bolts provided under the roof rack load bar and into the mounting holes of the box and the easy-snap hardware. Push the U-bolts up until they fit snugly.

  9. 9

    Turn the blue handle on the easy-snap bracket clockwise until it clicks into place then press the safety tab down.

  10. 10

    Check the rear hatch and front hood to make sure they will open with the box installed. If not, you'll have to adjust the cargo box's position.

Tips and warnings

  • All four mounting brackets must be attached and locked through the proper holes between the inside of the box and the roof rack's load bars. Make sure that the easy-snap mounting hardware is fully seated in the holes of your box and roof rack system.
  • Secure all loads with the load straps provided before driving.
  • Make sure that all loads are evenly distributed inside your cargo box and do not exceed the maximum weight permitted by the manufacturer of the box or your vehicle.
  • Clean your Thule cargo box with water and a mild soap that contains no alcohol, chlorine or ammonia which can damage the box's surface. Your cargo box locks should be lubricated regularly with graphite or a similar dry lubricant.
  • Inspect bolts, screws and all other fastenings on your cargo box and roof rack system periodically for signs of wear. Replace them if you see signs of corrosion.
  • Thule cargo boxes are not intended for use on trailers or towed vehicles or for off-road use.
  • Remove cargo boxes when they aren't in use and before entering automatic car washes.
