Reverse Mirror Control
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
When the vehicle is shifted to R (shift lever in R) with the power mirror selector switch in the Left (or the Right) position, the driver's (or passenger's) side mirror tilts down automatically to help the driver's view. The mirror returns to the previous position when the shift lever is shifted out of R. The reverse mirror control is cancelled if the power mirror selector switch is in the center position.
