Subaru Forester: Reverse Automatic Braking (RAB) system (if equipped) / Handling of the sonar sensors
The 4 sonar sensors are located in the rear
bumper. To ensure the proper operation of
the Reverse Automatic Braking (RAB)
system, observe the following precautions.

- Do not affix any stickers or other items
on the sonar sensor or the bumper surface
near the sonar sensors.
- Always keep the rear bumper surface
near the sonar sensors clean.
- Do not modify the rear bumper.
- Do not paint the bumper near the sonar
sensors.
- Do not apply strong impacts to the rear
bumper near the sonar sensors. If a sensor
becomes misaligned, a system malfunction
may occur, including inability to detect
objects in the reversing direction. If any
strong impact is applied to the rear
bumper, contact a SUBARU dealer to
have the system inspected.
- Do not disassemble the sonar sensors.
NOTE
If the sonar sensors require repair or
replacement, or if the area of the rear
bumper near the sonar sensors requires
repair, paintwork or replacement,
contact your SUBARU dealer for
assistance.
