The following steps must be performed on each of the push-pins to remove the air dam: 1. Insert the tip portion of a flat-tip screwdriver into the push-pin slot and pull downward until the push-pin snaps loose. 3. Pull the push-pins and lower air dam assembly away from the retainers until the lower air dam is free. When you're back on roads, though, be sure to replace the air dam. 2. While continuing to pull downward on the push-pin, squeeze and turn the expandable end of the push-pin with a pair of pliers until it releases from the retainer. NOTICE: Operating your vehicle for extended periods without the front bumper lower air dam installed can cause improper air flow to the engine and may allow things like fog lamps or tow hooks on the front of your vehicle to be damaged. Always be sure to replace the front bumper air dam when you're finished off-road driving. 4-18
