–On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The I-LI system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– 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 the lane
camera unit.
– When the headlights are not
bright due to dirt on the lens or if
the aiming is not adjusted
properly.
– When strong light enters the lane
camera unit (for example, the 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).
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions:
• When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The I-LI system will
be deactivated for approximately 2 sec-
onds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the warning and assist func-
tions will resume. Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional):
• When the brake pedal is depressed.
• When the steering wheel is turned as far
as necessary for the vehicle to change
lanes.
• When the vehicle is accelerated during I-LI system operation.
• When the Intelligent Cruise Control (ICC) approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, a chime will
sound and the I-LI system will be turned off
automatically.
• “Not Available - Poor Road Conditions”: When the Vehicle Dynamic Control (VDC)
system (except Traction Control System
[TCS] function) or ABS operates.

BSW SYSTEM OPERATION
1. Side Indicator Light
2. BSW Indicator
The BSW system operates above approxi-
mately 20 mph (32 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 acti-
vated, the system chimes (twice), the side
indicator light flashes, and the BSW indica-
tor (2) illuminates (yellow) in the vehicle in-
formation display. The side indicator light
continues to flash until the detected ve-
hicle leaves the detection zone.
The side indicator light illuminates for a few
seconds when the power switch is placed
in the ON position.
The brightness of the side indicator light is
adjusted automatically depending on the
brightness of the ambient light.
If a vehicle comes into the detection zone
af ter the driver activates the turn signal,
then only the side indicator light flashes
and no chime sounds. For additional infor-
mation, refer to “BSW driving situations” in
this sectionThe BSW system automatically turns on
every time the EV system is started, as long
as it is activated using the settings menu
on the vehicle information display.

BSW DRIVING SITUATIONS

nates if a vehicle enters the detection zone
from behind in an adjacent lane.
Indicator on
Indicator off
Indicator flashing
Another vehicle approaching
from behind
Illustration 2: If the driver activates the
turn signal when another vehicle is in the
detection zone, then the system chimes
(twice) and the side indicator light flashes.
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 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.

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
O1
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.5–52).).
• 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.

• If the driver activates the turn signal be- fore a vehicle enters the detection zone,
the side indicator light will flash but no
