Quick Reference Guide
Honda Sensing® (P488)
Honda Sensing ® is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located in the lower bumper next to the fog
light
* and a front sensor camera mounted to
the interior side of the windshield, behind
the rearview mirror.
The camera is
located behind the
rearview mirror.
Front Sensor
Camera
Radar Sensor
The radar sensor is in
the lower bumper.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P 491)
Can assist you when there is a possibility of
your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The
CMBS
TM is designed to alert you when the
potential for a collision is determined, as
well as to reduce your vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.
Adaptive Cruise Control
(ACC) with Low Speed
Follow
* (P 501)
Helps maintain a constant vehicle speed and
a set following-interval behind a vehicle
detected ahead of yours and, if the detected
vehicle comes to a stop, can decelerate and
stop your vehicle, without you having to
keep your foot on the brake or the
accelerator.
Adaptive Cruise Control
(ACC)
* (P 518)
Helps maintain a constant vehicle speed and
a set following-interval behind a vehicle
detected ahead of yours, without you
having to keep your foot on the brake or
the accelerator.
Lane Keeping Assist
System (LKAS)
(P 533)
Provides steering input to help keep the
vehicle in the middle of a detected lane and
provides tactile and visual alerts if the
vehicle is detected drifting out of its lane.
Road Departure
Mitigation (RDM) System
(P 541) Alerts and helps to assist you when the
system detects a possibility of your vehicle
unintentionally crossing over detected lane
markings and/or leaving the roadway
altogether.

Rear Seats
The rear seats can be folded down separa tely to allow for additional storage space.
Pull the release lever and fold down the seat-
back.
■Folding Down the Rear Seats1 Folding Down the Rear Seats
The rear seat-back(s) can be folded down to
accommodate bulkier items in the cargo area.
To lock a seat-back upright, push it backwards until it
locks, so that the red tabs in the release lever go
down.
When returning the seat-back to its original position,
push it firmly back.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly. 2 Passenger Front Airbag Off Indicator P. 61
Make sure all items in the cargo area or items
extending to the rear seats are properly
secured. Loose items can fly forward if you have
to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold
down.

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 the
potential for a collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
1 Collision Mitigation Braking SystemTM (CMBSTM)
When the CMBS
TM activates, the engine may stop
automatically.
Start the engine by normal operation if the engine
stops.
2 Starting the Engine P. 451, 454
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It does not prevent collisions
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. 496

■How the system works1How the system works
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.
CMBS
TM does not function while VSA® is completely
disabled.
2.0 L engine models
The radar sensor is in
the lower bumper
next to the fog light
*.
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 are 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.

Adaptive Cruise Control (ACC) with Low Speed Follow*
Helps maintain a constant vehicle speed a nd 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 yo u having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows your 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. 548
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Spee d Follow only when
driving on expressways or freeways and in
good weather.
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 sto ps 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 (40km/h) or above.
■Shift position for ACC with Low Speed Follow: In ( D or (S.
The radar sensor is in
the lower bumper.
Be careful not to have
the radar sensor cover
strongly impacted.
The camera is
located behind
the rearview
mirror.
