3-4 Storage D-Ring Sliders There are four D-Ring sliders that move along rails on both sides of the cargo management area. These can be used as tie-downs when storing cargo. Installing D-Ring Sliders Cargo Net (Wagon) { WARNING Do not stack items higher than the upper end of the cargo net or hang anything from the net. Avoid items that have sharp edges or that apply excessive force to the net. If items are not properly stored, damage to the net could occur and items can be thrown about the vehicle. You or other could be injured. Always store items behind the net. For vehicles equipped with a cargo net, it can be used to store light loads, keeping them from falling over or being thrown into the cabin during heavy braking. The net should not be overloaded or used to store heavy loads. The loop of the D-Ring slider must be facing inward towards the storage area and the ring must be in the up position for proper usage. Push the button to move the D-Ring slider either towards the front or the rear of the vehicle. The rings can be locked into various positions along the rail. To install the D-Ring slider (A), insert it into the channel (B) located in the middle of each rail.
