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. 487
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 529
For directions on the prop er handling of the radar 
sensor, refer to the following page. 2 Radar Sensor  P. 531
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 at the 
lower part of the front 
bumper.
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 the system determines 
there is a chance of a collision with:
- Vehicles detected in front of you that ar e 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 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 CMBSTM may activate even when you are aw are 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 vehicle that is making a left or right turn.
■With Little Chance of a Collision1 With Little Chance of a Collision

uuHonda Sensing ®u Adaptive Cruise Control (ACC) with Low Speed Follow
Driving
Adaptive Cruise Control  (ACC) with Low Speed 
Follow
Helps maintain a constant vehicle speed and 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 vehicle, without you having  to keep your foot on the brake or the 
accelerator.
When ACC with Low Speed Follow slows y our vehicle by applying the brakes, your 
vehicle’s brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low 
Speed Follow. Use the brake pedal whenever 
necessary, and always keep a safe interval between 
your vehicle and other vehicles.
For directions on the prop er handling of the radar 
sensor, refer to the following page.
2 Radar Sensor  P. 531
3WARNING
Improper use of ACC with Low Speed 
Follow can lead to a crash.
Use ACC with Low Speed Follow only when 
driving on expressways or freeways and in 
good weather conditions.
3WARNING
ACC with Low Speed Follow has limited 
braking capability and may not stop your 
vehicle in time to avoid a collision with a 
vehicle that quickly stops in front of you.
Always be prepared to apply the brake 
pedal if the conditions require.
When to use
■Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead 
within ACC with Low Speed Follow range  – ACC with Low Speed Follow 
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range  – ACC with 
Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.
■Shift position for ACC with Low Speed Follow: In ( D.
The radar sensor is at the 
lower part of the front 
bumper.
The camera is 
located behind 
the rearview 
mirror.

camera equipped with this system.
2 Front Sensor Camera  P. 529
When the  MAIN button is pressed, both ACC with 
Low Speed Follow and the Lane Keeping Assist 
System (LKAS) are either turned on or off.
ACC with Low Speed Follow may not work properly 
under certain  conditions.
2 ACC with Low Speed Follow Conditions 
and Limitations  P. 499
When not using ACC with Low Speed Follow: Turn 
off adaptive cruise by pressing the MAIN  button. This 
also will turn off the Lane Keeping Assist System 
(LKAS).
Do not use ACC with Low Speed Follow under the 
following conditions:
•On roads with heavy traf fic or while driving in 
continuous stop and go traffic.
•On roads with sharp turns.•On roads with steep downhill sections, as the set 
vehicle speed can be exceeded by coasting. In such 
cases, ACC with Low Speed Follow will not apply 
the brakes to maintain the set speed.
•On roads with toll collection facilities or other 
objects between lanes of  traffic, or in parking 
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button on 
the steering wheel.
ACC (green) is on in the instrument panel.

■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when 
ACC with Low Speed Follow is automaticall y canceled. Any of these conditions may 
cause the ACC with Low Speed Fo llow to automatically cancel:
• Bad weather (rain,  fog, snow, etc.)
• When the radar sensor at the lower  part of the front bumper gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the  ACC with Low Speed Follow range is too 
close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including 
the windshield, gets dirty.
• When the Maximum Load  Limit is exceeded.
• When passing through an enclos ed space, such as tunnel.
1Automatic cancellation
Even though ACC with Low Speed Follow has been 
automatically canceled, you can still resume the prior 
set speed. Wait until the  condition that caused ACC 
with Low Speed Follow to cancel improves, then 
press the  SET/– button.
