I would check your owners manual to double check if the car is towable 4 down or with a dolly. It's listed under 'recreational towing' in the manual.
THIS should be your bible not anyone else' info when dealing with all the different manuf.types of a Tracker.
Just a heads up about Trackers that I experienced that might save you some headaches! :W
I had a Chevy Tracker and because the Tracker went thru so MANY different manufacturing plants and actually changing in the middle of years, etc.
I.E. These are essentially the same car but can be totally different when trying to get info/parts: Chevy, Geo, Suzuki. ANY info outside the box of the actual manual that came with it can be incorrect.
Especially when Regarding 'how' to tow it, if you have to start it, what position to leave the key in when towing, if you had to add a pump etc etc.
I had a "Chevy" Tracker yet many of the parts had to be ordered under "Geo" Tracker AND even at that you would get the wrong parts. Forget to look up 4 door and could affect if you got the right light bulb!!
When I had the base plate ordered for my "Chevy" Tracker when the base plate came in it didn't fit. They had to order the one for a "Suzuki" Tracker and when THAT one came in we found out it was imperative to note that it was a 4 door because that actually was yet another different model base plate. :S
So bottom line what others do with their Tracker might not be correct for the type of Tracker you have.
