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 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 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. 541
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 487
Be careful not to severely impact the radar sensor
cover.
1 How the system works
Rapid vibrations on the steering wheel alert you
when your vehicle speed is between 19 and 62 mph
(30 and 100 km/h) with an oncoming vehicle
detected in front of you.
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 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 collis ion. 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 thes e conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.

■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 reflec ted 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 interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on curvy, winding, or undulating roads.
■CMBSTM Conditions and Limitations1CMBSTM Conditions and Limitations
Do not paint, or apply any coverings or paint to radar
sensor area. This can impact CMBS
TM operation.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle impacted a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.•Your vehicle has a frontal collision.
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 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, tra in 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 CMBS
TM 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 put a sticker on the radar sensor cover or
replace the radar sensor cover.

The corner and center sensors monitor obstacles around your vehicle, and the
beeper and 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.
•The vehicle is on uneven su rface, such as grass,
bumps, 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.
•Objects directly under the bumper.
Do not put any accessories on or around the sensors.
