Using your Thule Apex XT rear hitch rack is easy. First, attach the rack to your vehicle's 1 - 1/4 - inch or 2 - inch receiver. Make sure it's properly secured. Then, unfold the bike arms if they're folded. To load a bike, place it in the cradle and use the ratcheting cradle strap to secure it tightly. Remember, each bike should not exceed 37.5 pounds. When you need access to the rear of your vehicle, just use the HitchSwitch lever to tilt the rack down. When not in use, fold down the bike arms to save space. As for maintenance, regularly check the hitch connection and the straps for any signs of wear. Clean the rack with mild soap and water to keep it in good condition. Avoid using abrasive cleaners that could damage the black finish. If you notice any parts are loose or damaged, replace them promptly to ensure the safety of your bikes during transport.
