Is the 2.4 engine the only one with VVT or did the later 2.2s also have it? Also, how do you tow these vehicles?

 

The later 2.2 also got the VVT. 2009-11, I think. Towing instructions are in your owner manual.

 

Rear wheels up all 2.0 and 2.2 and 2.4 very similar, for automatics

 

If you tow 4 down you need to pull the ABS (#44) fuse and unlock the steering wheel. If you are hard core towing you can get an electric pump to cool the trans fluid.
If 2 down, FRONT (drive wheels) up.
2009-2011 2.2L are VVT.
