    FINAL VEHICLE EXAMINATION

32. Examine the body panels to ensure that they are in a pre-installation condition. Test the electronic functions of the vehicle. Correct any inconsistencies.
33.  Ensure that hitch components work properly.

• Verify that the lock works correctly. Push in the safety lock on the latch block then unlock with key. The lock should slide back out with the key when unlocked.
• Verify that each accessory can be installed correctly. Use the following steps to install and remove each accessory that will be used with the hitch. (Rack Receiver and Ball Mount if purchased.)

1.  Prepare latching mechanism. Turn handle clockwise if needed.
2.  Firmly insert “post” of accessory into latch block until handle releases indicating that the accessory is latched.
3.  Push in the safety locking pin until it fully engages. The locking pin prevents the handle from turning when pushed in, and confirms that the block is securely latched onto the accessory. The safety locking pin will not depress if the accessory is not fully latched.
4. Use key to release safety locking pin.
5. While holding on to the accessory, rotate handle clockwise to release and remove the accessory.

• Verify that no part of the accessories come into contact with the body of the vehicle.

NOTICE: If the hitch is being installed by a professional, the installer is responsible for training the end user in the use and maintenance of the product.

• Accessory installation procedure:
  1. Prepare latching mechanism. Turn handle clockwise if needed.
  2. Firmly insert “post” of accessory into latch block until handle spins counter- clockwise indicating that the accessory is latched.
  3. Always depress the safety locking pin and check that it has fully engaged.
• Never use any accessory with the safety lock disengaged. Until the safety locking pin is engaged, the handle is able to turn. A fully engaged safety locking pin is confirmation that the accessory is properly latched into the latch block.
• Never use the rack receiver for towing. The rack receiver accessory is only to be used with payload carrying products, such as bike racks or luggage racks.
• Before each use, give the post of the accessory a light coating of lithium based grease.
• Before each use, inspect the hitch to ensure that all bolted connections are secure and that no cracks or damage are present. Do not tow with the hitch if cracks or damage outside of normal wear is found.
• Remove the Stealth accessories from the latch block after each use. Do not leave accessories plugged in for extended periods of time.
