Camera View Angle Inspection Mode (Models With Mirror HBA)

WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.

Diagnostic procedure:

Drive the vehicle under the following conditions with the high beam assist ON in the night time.

Activate the high beam assist operation (high beam assist indicator illuminates).
Drive at least 20 minutes in total at a vehicle speed of 55 km/h (34 MPH) or more, on a road with many straight sections and clear lane markings on both sides (white, orange and dashed lines are acceptable).

NOTE:

Always perform the operation under such ambience (dimness) that the high beam light can turn to ON/OFF automatically.
Avoid a road with only a center line.
Avoid a road where the strong wind can blow the vehicle from side to side, and also avoid weaving within a lane. (Because the vehicle may judge that the lane is not straight.)
