BSW SYSTEM OPERATION
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 activated,
the system chimes (twice) and the side indi-
cator light flashes. The side indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The side indicator light illuminates for a few
seconds when the ignition 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
after the driver activates the turn signal, then
only the side indicator light flashes and no
chime sounds. For additional information, re-
fer to “BSW driving situations” in this section.

Illustration 1:The side indicator light illumi-
nates if a vehicle enters the detection zone
from behind in an adjacent lane.
Illustration 2:If the driver activates the turn
signal when another vehicle is in the detec-
tion 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 be-
fore 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 illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 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 after the first vehicle
may not be detected if they are traveling
close together.
∙ The radar sensors may not detect slower
moving vehicles if they are passed
quickly.

Illustration 5: The side indicator light illumi-
nates 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 be-
fore a vehicle enters the detection zone,

BSI SYSTEM OPERATION
The 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 system
chimes (twice) and the side indicator light
flashes. The side indicator light continues to
flash until the detected vehicle leaves the
detection zone.
If the BSI system is on and your vehicle ap-
proaches a lane marker while another vehicle
is in the detection zone, the system chimes
(three times) and the side indicator light
flashes. The BSI system activates to help re-
turn the vehicle back to the center of the
driving lane. The BSI system operates regard-
less of turn signal usage.

BSI DRIVING SITUATIONS
Another vehicle approaching from
behind
Illustration 1: The side indicator light illumi-
nates if a vehicle enters the detection zone
from behind in an adjacent lane.
However, if the overtaking vehicle is traveling
much faster than your vehicle, the indicator
light may not illuminate before the detected
vehicle is beside your vehicle. Always use theside and rear mirrors and turn and look in the
direction your vehicle will move to ensure it is
safe to change lanes.
Illustration 2: If the driver activates the turn
signal then the system chimes a sound (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.

vehicle approaches a lane marker while an-
other vehicle is in the detection zone the sys-
tem chimes a sound (three times) and the side
indicator light flashes. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.

Illustration 10: If the driver activates the turn
signal while another vehicle is in the detection
zone, then the side indicator light flashes and
a chime will sound twice.
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 another vehicle is detected.Illustration 11: If the BSI system is on and
your vehicle approaches the lane marker
while another vehicle is in the detection zone,
the side indicator light flashes and a chime
will sound three times. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.
NOTE:
∙ Illustration 12: The BSI system will not
operate if your vehicle is on a lane marker
when another vehicle enters the detec-
tion zone. In this case, only the BSW sys-
tem operates.
∙ BSI braking will not operate or will stop
operating and only a warning chime will
sound under the following conditions:
– When the brake pedal is depressed.
– When the vehicle is accelerated dur-
ing BSI system operation.
