walls on each side of the vehicle narrows.
The walls at the entrance and exits of tunnels,
turnouts.
A BSM warning indicator light may flash or the warning beep and the warning screen
indicator display 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.
In the following cases, it may be difficult to view the illumination/flashing of the BSM
warning indicator lights equipped on the door mirrors.
