When Driving- Page 235



Under the following conditions, the rear
side radar sensor cannot detect target
objects or it may be difficult to detect
them.



The rear bumper around the rear side
radar sensor is deformed.



Radio wave interference from a radar
sensor equipped on a nearby vehicle.



The approaching vehicle is any of the
following shapes.
a) The size of the vehicle body is

extremely small.

b) The vehicle height is extremely low

or high.

c) A special type of vehicle with a

complex shape.



A vehicle is in the detection area at
the rear in an adjacent driving lane
but it does not approach. The BSM
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
side radar sensor is set at the road
width of expressways.



In the following case, the flashing of the
BSM warning indicator light, and the
activation of the warning sound and the
warning screen indicator display 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 slopes.



Crossing the summit of a hill or
mountain pass.



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 rear side radar
sensor 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.

1. Objects such as guardrails and

concrete walls running alongside the
vehicle.
