■Situations in which the system
may not operate properly
●Some pedestrians, such as the
following, may not be detected by
the rear camera detection func-
tion, preventing the function from
operating properly:
• Pedestrians who are bending for- ward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skate- board, or other light vehicle • Pedestrians wearing oversized
clothing such as a rain coat, long
skirt, etc., making their silhouette
obscure
• Pedestrians whose body is par- tially hidden by an object, such as
a cart or umbrella
• Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the
following, pedestrians may not be
detected by the rear camera
detection function, preventing the
function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is
obscured (dirt, snow, ice, etc., are
attached) or scratched
• When a very bright light, such as
the sun, or the headlights of
another vehicle, shines directly
into the rear camera
• When backing up in a place where the surrounding brightness
changes suddenly, such as at the
entrance or exi t of a garage or
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in
an underground parking lot
• When the camera position and
direction are deviated
• When a towing hook is attached
• When water droplets are flowing on the camera lens
• When the vehicle height is extremely changed (nose up,
nose down).
• When tire chains or an emergency tire puncture repair kit is used
■Situations in which the system
may operate unexpectedly
●Even though there are no pedes-
trians in the detection area, some
objects, such as the following,
may be detected, possibly caus-
ing the rear cam era detection
function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or
parked vehicle
• Moving objects, such as a car or

2725-5. Using the driving support systems
Owners Manual_USA_M62084_enmotorcycle
• Objects moving toward your vehi- cle when backing up, such as
flags or puddles (or airborne mat-
ter, such as smoke, steam, rain, or
snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines,
pedestrian crossings or fallen
leaves on the road
• Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on a wet road surface

●In some situations, such as the
following, the rear camera detec-
tion function may operate even
though there are no pedestrians in
the detection area.

• When backing up toward an
incline/decline
• If the rear of the vehicle is raised or lowered due to the carried load

• If a towing eyelet is installed to the
rear of the vehicle
• When water is flowing over the rear camera lens
• When the rear camera is obscured (dirt, snow, ice, etc., are
attached) or scratched
• If there is a flashing light in the detection area, such as the emer-
gency flashers of another vehicle
• When a tire chains or an emer- gency tire puncture repair kit is
used
●Situations in which the rear cam-
era detection function may be diffi-
cult to notice
• The buzzer may be difficult to hear if the surrounding area is noisy,
the volume of the audio system
volume is high, the air condition-
ing system is being used, etc.
• If the temperature in the cabin is extremely high or low, the audio
