Islhrbr

It is a 2011 SEL and we have looked at the manual, gone to the settings - they are on, but still no lines. We turned them off, then back on, still nothing. And yes, we have done that with the vehicle in park. It beeps as usual when you are getting close to an object but the red and yellow guidelines are gone.

The guidelines on our screen have disappeared. Searching our owner guide has not yielded any helpful info. Anyone know the answer?
