I don't have a Passat, and I can't imagine any reason that it would be different than any other FWD sedan...just hook-up and go...but maybe someone here has more insight.
- BUT - DO NOT USE THE "CHAIN" Automatic Restraint System (ARS) that may have come from the Mfgt. They have discontinued it because it does not allow enough "pivot point" on the wheel tray during turns.
See "What Exactly is the ARS here: FAQs | Car Tow Dolly
The name "ARS" now describes the design of the web strap with a single front strap and slide mounted winch.
This should not be confused with the safety chains - those should always be used.
REASON: The front wheels of the toad must be able to pivot during turns. If the toad's wheels cannot pivot during turns the dolly wheels will scrub sideways plus tremendous side pressures will be created in the toad's front suspension during the turns.
If your Passat has steering lock, ensure it is unlocked during the tow.

Finally, the toad's wheels do not need to spin (toad can be left in park) but it doesn't hurt if you expect to be making very tight turns during the tow.
Best of luck and safe travels
BTW, I have over 10,000miles on my EzeTow, I bought it used, and I Love It! So simple and EZE to use.
