I am fan of hypermiling to save fuel. One of the steps is on downhill stretches or coasting up to a light that I know will be red, I’ll shift the vehicle from drive to neutral (and back to drive when I’m done with the downhill coasting). If I’m coasting up to a light that I know will be red for long, I will turn off the engine. I do this with my Honda Civic and Chevy Silverado. However, with my 2011 Elantra, there is a notice in the manual (5-17) to “Always come to a complete stop before shifting into D”. I’m aware that Hyundai has a new transmission in this vehicle.

So the question is: Can I still shift the Elantra into neutral from drive while the vehicle is moving and shift it back into drive from neutral while the vehicle is moving without damaging the transmission.

Thanks!
