•When there is a difference in the height between your driving lane and the adjacent
lane.
•Directly after the BSM system becomes operable by changing the setting.
•If the road width is extremely narrow, vehicles two lanes over may be detected. The
detection area of the radar sensors (rear) is set according to the road width of
expressways.
•The BSM warning indicator light may turn on and the vehicle detection screen may be
displayed in the display in reaction to stationary objects (guardrails, tunnels, sidewalls,
and parked vehicles) on the road or the roadside.
Objects such as guardrails and concrete walls
running alongside the vehicle. Places where the width between guardrails or
walls on each side of the vehicle narrows.

and turnouts.
•A BSM warning indicator light may flash or the warning beep may be activated several
times when making a turn at a city intersection.
•Turn off the BSM while pulling a trailer or wh
ile an accessory such as a bicycle carrier is
installed to the rear of the vehicle. Otherwise, the radar’s radio waves will be blocked
causing the system to not operate normally.

warning indicator lights equipped on the door mirrors.
•Snow or ice is adhering to the door mirrors.
•The front door glass is fogged or covered in snow, frost or dirt.
•The radar sensors (rear) of the BSM may be regulated under the radio wave related laws
of the country where the vehicle is driven. The sensors in this system are approved for use
in the U.S.A. (including territories), and Canada. If a vehicle with a BSM is driven in a
country other than the U.S.A., or Canada, the system has to be turned off by changing the
