3. Dynamic driver assistance switch (formodels without ProPILOTAssist)
4. ProPILOT Assist switch (for vehicles with ProPILOT Assist)
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. NOTE:
∙ BSI warning and system application will
only be activated if the side indicator
light is already illuminated when your
vehicle approaches a lane marker. If an-
other vehicle comes into the detection
zone after your vehicle has crossed a lane
marker, no BSI warning or system appli-
cation will be activated. For additional
information, refer to “BSI driving situa-
tions” in this section.
∙ The BSI system is typically activated
earlier than the Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.
The BSI system turns on when the dynamic
driver assistance switch (for models without
ProPILOT Assist) or the ProPILOT Assist
switch (for models with ProPILOT Assist) on
the steering wheel is pushed when the “Blind
Spot Intervention” is enabled in the “Driver
Assistance” menu in the lower display. The
BSI ON indicator light on the instrument
panel illuminates when the BSI system is
turned on. The BSI system provides a chime and turns on
or flashes the side indicator light even if the
BSW system is off.

HOW TO ENABLE/DISABLE THE
BSI SYSTEM
When the BSI system is enabled in the lower
display, the system can be turned off tempo-
rarily by pushing the dynamic driver assis-
tance switch (for models without ProPILOT
Assist) or the ProPILOT Assist switch (for
models with ProPILOT Assist) on the steer-
ing wheel.
Perform the following steps to enable or dis-
able the BSI system:1. Press the MENU button below the lower display screen.
2. Select “Driver Assistance.”
3. Select “Blind Spot Assist.”
4. Select “ON” to turn the “Blind Spot Inter- vention” system on or off.
∙ Select the “-” or the “+” to change the “Side Indicator Brightness” and set it to
either “Standard”, “Bright” or “Dark.”

BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSI system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The BSI system cannot detect all vehiclesunder all conditions.
∙ The radar sensors may not be able to de- tect and activate BSI when certain ob-
jects are present such as:
– Pedestrians, bicycles, or animals.
– Vehicles such as motorcycles, low height vehicles, or high ground clear-
ance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detection zone when you accelerate from a stop.
For additional information, refer to
“BSI driving situations” in this section.
– A vehicle merging into an adjacent lane at a speed approximately the
same as your vehicle. For additional
information, refer to “BSI driving situ-
ations” in this section. – A vehicle approaching rapidly from
behind. For additional information,
refer to “BSI driving situations” in this
section.
– A vehicle which your vehicle overtakes rapidly. For additional information,
refer to “BSI driving situations” in this
section.
– A vehicle that passes through the de- tection zone quickly.
– When overtaking several vehicles in a row, the vehicles after the first vehicle
may not be detected if they are trav-
eling close together.
∙ The radar sensors’ detection zone is de- signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an ad-
jacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
∙ The radar sensors are designed to ignore most stationary objects; however, ob-
jects such as guardrails, walls, foliage and
parked vehicles may occasionally be de-
tected. This is a normal driving condition. ∙ The following conditions may reduce the
ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt build-up on the vehicle
∙ Do not attach stickers (including trans- parent material), install accessories or
apply additional paint near the radar sen-
sors. These conditions may reduce the
ability of the radar to detect other
vehicles.
∙ The camera may not detect lane markers in the following situations and the BSI
system may not operate properly:
– On roads where there are multiple 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 lane markers are still detectable.
– On roads where there are sharp curves.
Starting and driving5-57

– On roads where there are sharply con-trasting objects, such as shadows,
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 direction does not align with the lane markers.
– When traveling close to the vehicle in front of you, which obstructs 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 cam- era unit (e.g., light directly shines on
the front of the vehicle at sunrise or
sunset).
– When a sudden change in brightness occurs (e.g., when the vehicle enters or
exits a tunnel or under a bridge). ∙ Do not use the BSI system under the fol-
lowing conditions because the system
may not function properly:
– During bad weather (e.g., rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift 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, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BSI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.

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 the
side 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.

Illustration 3: If the BSI system is on and your
vehicle is approaching a lane marker and a
vehicle is in the detection zone, the system
chimes a sound (three times), and the side
indicator light flashes. Then the BSI system
slightly applies the brakes on one side to help
return the vehicle back to the center of the
driving lane.NOTE:

with a vehicle in the detection zone, the
other vehicle may not be detected.Overtaking another vehicle
Illustration 5: The side indicator light illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.
