My guess is that your auto-leveling headlights aren't adjusting right. Check for dirt and debris around the lights. Also check to see if any of your lights or drls are out.

 

Looks like you might have an even bigger problem with that check engine light...

 

Why do you say that

 

The CEL might just have been if the key was only partially turned. When all the electrics work, but the engine isn't started. If the engine was started during this picture, however, get it checked out. Looks like the light is an issue with the auto-leveling headlights to me.
