Cruise control - normal?
 

Re: 2007 Camry LE

When I have cruise on and I am on a relatively flat road (ie no upward or downward hills), the cruise stays at target/set speed.

When I have cruise on and I am going up a hill the engine revs way up and the speed goes significantly beyond the target/set speed and stays higher than target for significant time before it falls back to target/set speed.

I thought cruise was supposed to keep it at target/set speed no matter what the conditions? Is the above normal?

Thanks
