Adaptive Cruise Control (ACC) with Low Speed 
Follow (LSF)
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle 
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate 
and stop your ve hicle, without you having to keep your foot on the brake or the 
accelerator.
When ACC with LSF slows your vehicle by  applying the brakes, your vehicle's brake 
lights will illuminate.

LaneWatchTM
LaneWatch is an assistance system that allows you to check the passenger side rear 
areas displayed on the audio/information screen  when the turn signal is activated to 
the passenger’s side. A camera in the pass enger side door mirror monitors these 
areas and allows you to chec k for vehicles, in addition to your visual check and use 
of the passenger door mirror. You can also keep the system on for your convenience 
while driving.1 LaneWatchTM
Important Safety Reminder
Like all assistance systems, LaneWatch has 
limitations. Over reliance on LaneWatch may result in 
a collision.
The LaneWatch function can be  affected by weather, 
lighting (including headli ghts and low sun angle), 
ambient darkness, camera  condition, and loading.
The LaneWatch may not prov ide the intended display 
of traffic to the side and rear under the following 
conditions:
•Your vehicle’s suspensi on has been altered, 
changing the height of the vehicle.
•Your tires are over or under inflated.•Your tires or wheels are of varied size or 
construction.

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 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. 432
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 383
Be careful not to severely  impact the radar sensor 
cover.
1 How the system works
Rapid vibrations on the  steering wheel alert you 
when the your vehicle speed is between 19 and 62 
mph (30 and 100 km/h) with an oncoming vehicle 
detected in front of you.
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 radar sensor is 
behind the emblem.
The camera is 
located behind 
the rearview 
mirror.
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.
When to use
The CMBSTM 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.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Driving
• When there is a group of people in front of your vehicle walking together side by 
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s 
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorter than about 3.3 feet (1 me ter) or taller than about 
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squa tting, or when their hands are raised or 
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify  that a pedestrian is present due to an 
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself off and the CMBSTM indicator comes and 
stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain ro ad, or curved and winding road for an 
extended period.
• An abnormal tire condition is detected  (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including 
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed 
(e.g., cleaning), the system comes back on.
