If the warning light in the instrument
cluster remains illuminated, have the
vehicle inspected at an authorized
dealer as soon as possible.
Note:
Under the following conditions, the rear
radar sensors cannot detect objects, or
it may be difficult to detect them:
A vehicle is in the detection area at
the rear in an adjacent driving lane but
it does not approach. The BSM system
determines the condition based on
radar detection data.
A vehicle is traveling alongside your
vehicle at nearly the same speed for an
extended period of time.
Vehicles approaching in the
opposite direction.
A vehicle in an adjacent driving lane
is attempting to pass your vehicle.
A vehicle is in an adjacent lane on a
road with extremely wide driving lanes.
The detection area of the rear radar
sensors is set at the road width of
expressways.

In the following cases, the activation of
the BSM warning lights and the audible
alert may not occur, or they may be
delayed:
A vehicle makes a lane change from
a driving lane two lanes over to an
adjacent lane.
Driving on steep inclines.
Crossing the summit of a hill or
mountain pass.
The turning radius is small (making a
sharp turn or turning at intersections).
When there is a difference in the
height between your driving lane and
the adjacent lane.
Immediately after pushing the BSM
switch and the system becomes
operable.
If the road width is extremely narrow,
vehicles two lanes over may be
detected. The detection area of the rear
radar sensors is set according to the
road width of expressways.
The BSM warning lights may turn on in
reaction to stationary objects on the
road or the roadside such as guardrails,
tunnels, sidewalls, and parked vehicles.
A BSM warning light may flash or the
audible alert may be activated several
times when making a turn at a city
intersection.
Turn off the BSM system while pulling a
trailer or while an accessory such as a
bicycle carrier is installed to the rear of
the vehicle. Otherwise, the radar's
sound system 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 lights equipped on the
door mirrors:
Snow or ice is adhering to the door
mirrors.
The door glass is fogged or covered
in snow, frost or dirt.
The system switches to the Rear Cross
Traffic Alert function when the gear
selector is shifted to the REVERSE
position.
