Radar Axis Adjustment

WARNING: This page is about a different car, the 2016 Subaru Outback and 2016 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

After removal/installation or replacement of the radar sensor, perform the radar axis adjustment.
The procedure for the master is only shown here. However the procedure for the slave can also be done in the same way as the master.

Before performing the inspection, check the following items.
- The inflation pressure of tires is correct.
- The vehicle does not have load.
- Vehicle's fuel tank is fully filled.
Place the vehicle on a level surface, where approximately 5 square meters (16.41 square ft) area can be secured behind the vehicle.
CAUTION:
- No metallic objects around the vehicle and on the floor in the area.
- Do not let in objects other than the radar reflector (ST), persons and metallic objects inside the area.
NOTE: The illustration shows the secured area for adjusting the radar axis on the master side.

Set up the radar reflector.
NOTE: The following procedure explains the method of setting the radar reflector so that the distance between radar reflector and radar sensor is 1, 500 mm (4.92 ft) and the radar is positioned at an angle of 50 degree.
1. Suspend the plumb bob from the center of the front hole cap, and mark the position where the plumb bob touches the ground. (Point A)
