■When the system detects a vehicle
Blind spot information System Alert Indicator:
Located near the pillar on both sides.
Comes on when:
•A vehicle enters the alert zone from behind
to overtake you with a speed difference of
no more than 31 mph (50 km/h) from your
vehicle.
• You pass a vehicle with a speed difference
of no more than 12 mph (20 km/h).
Blinks and the beeper sounds when:
You move the turn signal lever in the direction
of the detected vehicle. The beeper sounds
three times.1 Blind spot information System
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.
•The blind spot informatio n system alert indicator
may not come on due to obstruction (splashes,
etc.) even without the Blind spot information
system not available driver information interface
appearing.
•The blind spot informatio n system alert indicator
may come on even with the message appearing.
You can change the setting for the blind spot
information system. 2 Customized Features P. 345
Turn the system off when towing a trailer.
The system may not work properly for the following
reasons:
•The added mass tilts the vehicle and changes the
radar coverage.
•The trailer itself can be detected by the radar
sensors, causing the blind spot information system
alert indicators to come on.

■Blind spot information System On and Off
When you turn the blind spot information
system on and off, do the following.
1. Press the safety support switch.
2. Roll the right selector wheel to the
symbol and push it.
u The message appears on the driver
information interface when the system
becomes on or off.
u A check mark appears in the box and the
color of the symbol changes green
when the system is on. The check mark
disappear and the color of the symbol
changes gray when the system is off.
The blind spot information system is in the
previously selected on (checked) or off
(unchecked) setting eac h time you start the
engine.1 Blind spot information System
You can also select the safety support content from
the driver information interface.

Blind spot information sy stem may be adversely
affected when:
•Objects (guard rails, poles, trees, etc,.) are
detected.
•An object that does not re flect radio waves well,
such as a motorcycle, is in the alert zone.
•Driving on a curved road.
•A vehicle is moving from a far lane to the adjacent
lane.
•The system picks up external electrical interference.
•The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed.
•The orientation of the sensors has been changed.
•In bad weather (Heavy rain, snow, and fog).•Making a turn at an intersection.
•Driving on a bumpy road.
•Making a short turn that slightly tilts the vehicle.
For a proper blind spot in formation system operation:
•Always keep the rear bumper corner area clean.•Do not cover the rear bumper corner area with
labels or stickers of any kind.
•Take your vehicle to a dealer if you need the rear
bumper corner area or th e radar sensors to be
repaired, or the rear bumper corner area is strongly
impacted.

Collision Mitigation Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when the
potential for a collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
1 Collision Mitigation Braking SystemTM (CMBSTM)
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 549
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 547
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions: 2 CMBS
TM Conditions and Limitations P. 484
The CMBS
TM is not activated for about 15 seconds
after the power system is turned on.

■How the System Works1How the System Works
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
behind the emblem.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system
determines there is a chance of a collision with:
- Vehicles detected in front of you that are stationary, oncoming, or traveling
in your same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines
there is a chance of a collision with a vehicle detected in front of you traveling
in your same direction. The camera is
located behind the
rearview mirror.

the stages before initiating the last stage.

Driving
Low Speed Braking Control*
Using sonar sensors located on the front an d rear bumpers, this system detects if
there is danger of a potential collision with a wall or other obstacle during normal
driving or when the accelerator pedal is de pressed with too much force. The system
then assists in avoiding collisions and reducing damage from impact through
assistive braking and/or assistive driving power suppression.1 Low Speed Braking Control*
If trapped in a railway crossing, the system may
detect the crossing gate as an obstacle and activate.
If this happens, assistive braking will automatically
cancel after a certain amount of time after stopping,
so continue to move forw ard. If assistive driving
power suppression is activate d, continue to calmly
depress the accelerator or depress the accelerator
once again, then push aside the crossing gate.
3WARNING
It is not possible for the Low Speed Braking
Control system to avoid collisions or reduce
damage from collision s in all situations
where the accelerator has been depressed
accidentally or with too much force.
Over reliance on this system may result in a
collision and serious injury or death.
It is your responsibility to always check your
shift position, pedal location and
surroundings, and safely operate the
vehicle.
