uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Continued
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 shorte r than about 3.3 feet (1 meter) 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 squatting, 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 o ff and the safety support indicator
(amber) comes and stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, 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.
Limitations applicable to pedestrian detection only

uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Driving
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 Collision

Driving
■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 traffic sign and guard rail) on a curve or, when
parking, stationary vehicles and walls.

uuHonda Sensing ®u Adaptive Cruise Control (ACC) with Low Speed Follow*
Driving
Adaptive Cruise Control (A CC) 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.
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 qu ickly stops in front
of you.
Always be prepared to apply the brake
pedal if the cond itions 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.

■How to activate the system1Adaptive Cruise Control (ACC) with Low Speed Follow*
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. 528
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

Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the SET/– button when you reach the de sired speed. The moment you
release the button, the set speed is fixed, and ACC with Low Speed Follow begins.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the button fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
When ACC with Low Speed Follow starts
operating, the vehicle icon, interval bars and
set speed appear on the driver information
interface.
When you use ACC with Low Speed Follow,
Straight Driving Assist (a feature of the Electric
Power Steering system) is activated.
By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicl e in a straight line.

■There is a vehicle ahead
ACC with Low Speed Follow m onitors if a vehicle ahead of you enters the ACC with
Low Speed Follow range. If a vehicle is de tected doing so, the ACC with Low Speed
Follow system maintains or decelerates your vehicle’s set speed in order to keep the
vehicle’s set following interval from the vehicle ahead.
2 To Set or Change Following Interval P. 532
When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■When in Operation1 When in Operation

Driving
■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.
■When you depress the accelerator pedal
You can temporarily increase th e vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unless you cancel it. Once you release the
accelerator pedal, the system resume s an appropriate speed for keeping the
following interval while a vehicle ahead is within the ACC with Low Speed Follow
range.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerati ng your vehicle under the
following circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC with
Low Speed Follow detect ing range. Change the ACC
Forward Vehicle Detect Beep setting.
