BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSI system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The BSI system cannot detect all
vehicles under all conditions.
. The radar sensors may not be able to
detect and activate BSI when certain
objects are present such as:
— Pedestrians, bicycles, animals.
— Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
— Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
— Oncoming vehicles.
— A vehicle merging into an adja- cent lane at a speed approxi-
mately the same as your vehicle.
— A vehicle approaching rapidly from behind. — A vehicle which your vehicle over-
takes rapidly.
— A vehicle that passes through the detection zone quickly.
. The radar sensor’s detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect
vehicles in an adjacent lane. When
driving in a narrow lane, the radar
sensors may detect vehicles driving
two lanes away.
. The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a
normal operation condition.
. The camera may not detect lane
markers in the following situations
and the BSI system may not operate
properly.
— On roads where there are multi- ple parallel lane markers; lane
markers that are faded or not
painted clearly; yellow painted
lane markers; non-standard lane
markers; lane markers covered
with water, dirt, snow, etc.

— On roads where discontinued lanemarkers are still detectable.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs.
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane markers.
— When traveling close to the ve- hicle in front of you, which ob-
structs the lane camera unit
detection range.
— When rain, snow or dirt adheres to the windshield in front of a lane
camera unit.
— When the headlights are not bright due to dirt on the lens or
if aiming is not adjusted properly.
— When strong light enters a lane camera unit. (For example: light
directly shines on the front of the
vehicle at sunrise or sunset.) — When a sudden change in bright-
ness occurs. (For example: when
the vehicle enters or exits a tunnel
or under a bridge.)
. Do not use the BSI system under the
following conditions because the sys-
tem may not function properly.
— During bad weather. (For exam- ple: rain, fog, snow, etc.)
— When driving on slippery roads, such as on ice or snow, etc.
— When driving on winding or un- even roads.
— When there is a lane closure due to road repairs.
— When driving in a makeshift or temporary lane.
— When driving on roads where the lane width is too narrow.
— When driving with a tire that is not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts. — When towing a trailer or other
vehicle.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.
