Default competitive driving mode???

For some reason my car won't go into comp driving mode. Wanted to see if anyone had a simple solution as to why. Change oil light just came on a few days ago, wonder if that has anything to do with it.

Thanks.

I would think you would have seen a 'service tire monitor' warning but are all your tire pressure sensors registered correctly and working properly? If you have one or more TPS's 'out' you can't engage comp mode. Just a thought. Good luck!

If you have the wrong diameter tires either F or R the computer gets confused and locks out Comp. mode.

No tire pressure sensor alarms, but I will check manually to make sure. Thanks.

On my 08 if my steering wheel is turned to far to the left or right it will not go into CDM. It has to be nearly straight ahead.

If you mean a 9.5" rim from an 8.5" rim----- The rim width doesn't matter, it's the DIAMETER of the tire you put on the wheel. The tire diameter depends on the sidewall width and the aspect ratio. I.E;

A 275/35/18 tire on an 18" X 9.5" rim is close to the same overall diameter as a 245/40/18 on an 18" X 8.5" rim.

Wayne O, you are on the spot. After checking, my left rear is registering 0, but manually have 31 pounds so this is obviously the issue. Thanks for the help.
