Subaru Legacy BN/BS (2015-2019) Owners Manual: Rear gate drop prevention function

If, while fully opened via the power rear gate function, the rear gate is lowered by the weight of snow and such, an electronic chirp will sound and the rear gate drop prevention function will apply braking to the rear gate so that it prevents a rapid closure of the rear gate.

NOTE

•  If there is snow on the rear gate, only use the power rear gate function after removing the snow.
•  If you close the rear gate manually just after the rear gate is fully opened using the power rear gate function, the rear gate drop prevention function will detect a rapid closure of the rear gate and apply braking to the rear gate. In this case, this is not a malfunction.
