BSW SYSTEM OPERATION
1. Side Indicator Light
2. BSW IndicatorThe 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, see “BSW driving situations”
(P. 5-40).
The 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
Illustration 1:The side indicator light illumi-
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.

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.
