NOTE:
• The radar sensors may not detect ve-hicles which are approaching rapidly
from behind.
• If the driver activates the turn signal before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected.
Overtaking another vehicle
Illustration 3: The side indicator light illu-
minates if you overtake a vehicle and that
vehicle stays in the detection zone for ap-
proximately 2 seconds. Illustration 4:
If the driver activates the
turn signal while another vehicle is in the
detection zone, then the system chimes
(twice) and the side indicator light flashes.
NOTE:
• When overtaking several vehicles in a row, the vehicles af ter the first vehicle
may not be detected if they are travel-
ing close together.
• The radar sensors may not detect slower moving vehicles if they are
passed quickly.

• If the driver activates the turn signalbefore a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected.
Entering from the side
Illustration 5: The side indicator light illu-
minates if a vehicle enters the detection
zone from either side. Illustration 6:
If the driver activates the
turn signal while another vehicle is in the
detection zone, then the system chimes
(twice) and the side indicator light flashes.
NOTE:
• If the driver activates the turn signal before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected.
• The radar sensors may not detect a ve- hicle which is traveling at about the
same speed as your vehicle when it en-
ters the detection zone.

I-BSI SYSTEM OPERATION
The I-BSI system operates above approxi-
mately 37 mph (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light (1)
illuminates.
If the turn signal is then activated, the sys-
tem chimes (twice) and the side indicator
light flashes. The side indicator light contin-
ues to flash until the detected vehicle
leaves the detection zone. The brightness
of the side indicator light is adjusted auto-
matically depending on the brightness of
the ambient light.
If the I-BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. The I-BSI system activates to
help return the vehicle back to the center of
the driving lane. The I-BSI system operates
regardless of turn signal usage.

NOTE:
• I-BSI warning and system applicationwill only be activated if the side indica-
tor light is already illuminated when
your vehicle approaches a lane marker.
If another vehicle comes into the de-
tection zone af ter your vehicle has
crossed a lane marker, no I-BSI warn-
ing or system application will be acti-
vated. For additional information, see
“I-BSI driving situations” (P. 5-50).
• The I-BSI system is typically activated earlier than the Intelligent Lane Inter-
vention (I-LI) system when your vehicle
is approaching a lane marker.
To turn on the I-BSI system, push the ProPI-
LOT Assist switch on the steering wheel
(models with ProPILOT Assist) or the dy-
namic driver assistance switch (models
without ProPILOT Assist) af ter starting the
EV system. The I-BSI indicator will illumi-
nate. Push the ProPILOT Assist switch or
the dynamic driver assistance switch
again to turn off the I-BSI system. The I-BSI
indicator will turn off.
HOW TO ENABLE/DISABLE THE
I-BSI SYSTEMPerform the following steps to enable or
disable the I-BSI system:

–On roads where discontinued lane
markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs.
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion 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 de-
tection 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 I-BSI system under the
following conditions because the
system may not function properly.
– During bad weather (for example:
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 makeshif t 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 (e.g.,
tire wear, low tire pressure, instal-
lation of spare tire, tire chains,
nonstandard wheels).
– When the vehicle is equipped with
non-original brake parts or sus-
pension parts. •
Excessive noise (e.g., audio system
volume, open vehicle window) will in-
terfere with the chime sound, and it
may not be heard.
