prevents unnecessary upshifting.

doors using the smart entry & start system or wireless remote control will turn the front
position lights and tail lights on automatically.
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
