I notice that LS making when beep sound when you start drive it, what does it mean? I thought that it indicates that backup camera switched off, but it beeps even if you start driving forward.

 

Seems like the seat belts, did you wear it?

 

What about the "intuitive parking assist" feature. If you start out and are close enough to an obstacle it will beep - even fi you start driving forward. It should stop once you have moved away a little.

 

On my 2011 model there is an "eco" mode you can turn on, for supposedly lower gas usage. When it is on you see "eco' in the dash display. I have noticed when I am in this mode there is a beep as I drive away and the dash display comes on. The "eco" mode gets switched off if you move the gear shift to the left out of "D".

 

Thanks, it looks like you are right, it is indication that Eco mode active.
