1Blind spot inform ation (BSI) System*
BSI may be adversel y 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 sens ors have been improperly
repaired or the rear bu mper has been deformed.
•The orientation of the sensors has been changed.
•In bad weather (Heavy rain, snow, and fog).
For a proper BSI use:
•Always keep the rear bumper corner area clean.
•Do not cover the rear bumper corner area with
labels or sticke rs 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.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Driving
Collision Mitigati on 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 a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. 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. 328
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 284
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
in the front grille.
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 there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.

The system has three alert stages for a possible collision. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the CMBS

■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interior of the front windshield.
■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on curvy, winding, or undulating roads.

■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• An abnormal tire or wheel condition (wro ng sized, varied size or construction,
improperly inflated, compact spare tire
*, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heavy load or suspension modifications.
• The camera temperature gets too hot.
• Driving with the parking brake applied.
• When the radar sensor in the front grille gets dirty.
■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved, winding or und ulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehi cle and a vehicle in front of you is
significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in fr ont of you at an intersection, etc.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Driving
The CMBSTM may activate even when you are aware of a vehicle ahead of you, or
when there is no vehicle ahead. Some examples of this are:
■When Passing
Your vehicle approaches another vehicle ah ead of you and you change lanes to pass.
■At an intersection
Your vehicle approaches or passes another ve hicle that is making a left or right turn.
■On a curve
When driving through curves, your vehicle comes to a point where an oncoming
vehicle is right in front of you.
■Through a low bridge at high speed
You drive under a low or na rrow bridge at high speed.
■Speed bumps, road work sites, train tracks, roadside objects, etc.
You drive over speed bumps, st eel road plates, etc., or your vehicle approaches train
tracks or roadside objects [such as a traffi c sign and guard rail] on a curve or, when
parking, stationary vehicles and walls.
■With Little Chance of a Collision1 Collision Mitigation Braking SystemTM (CMBSTM)*
For the CMBSTM to work properly:
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not paint, or apply any coverings or paint to radar
sensor area. This can impact CMBS
TM operation.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the
CMBS
TM off button and take your vehicle to a dealer.

The corner and center sensors monitor obst acles near your vehicle. The beeper and
audio/information screen let you know the approximate distance between your
vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud or
dirt, etc.
•The vehicle is on uneven su rface, such as grass,
bumpy road, or a hill.
•The vehicle has been out in hot or cold weather.•The system is affected by devices that emit
ultrasonic waves.
•Driving in bad weather.
The system may not sense:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
