Honeytracker,. you can tow your Tracker automatic easily four wheels down, without a dolly. They make an excellent toad, and tow very good. Follow the steps below.
1. place transfer case in neutral (make certain of this by checking to see that the vehicle will not move when placed in gear, and if so equipped, that the 4wd light is not lit on the dash.
2. if you have manual hubs in front, place them in free position, if automatic hubs, do nothing.
3. place trans in neutral,(really doesn't matter}.
4. leave key in ignition switch in acc position,
make sure steering is unlocked, not necessary to have ign on. Make sure no accessories such as radio, or AC blower etc are left on, you don't want a dead battery.
I have towed our Grand Vitara many thousands of miles in this manner, and it is the same vehicle as your Tracker.
