Quick Reference Guide
Honda Sensing®
Honda Sensing® is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located in the front grille and a front sensor
camera mounted to the interior side of the
windshield, behind the rear view mirror.
The camera is located
behind the rearview
mirror.

Adaptive Cruise Control
(ACC) with Low Speed
Follow
(P485)
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, wi thout you having to
keep your foot on the brake or the
accelerator.
Road Departure
Mitigation (RDM) System
(P501)
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.
Lane Keeping Assist
System (LKAS)
(P505)
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.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P536)
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 a
potential collision is determined, as well as
to reduce your vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.

uuSeat Belts uAbout Your Seat Belts
Safe DrivingThe seat belt system includes an indicator on
the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts.
If the ignition switch is turned to ON
(w*1 and
a seat belt is not fastened, a beeper will sound
and the indicator will blink. After a few
seconds, the beeper will stop and the
indicator will come on and remain illuminated
until the seat belt is fastened.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■Seat Belt Reminder1 Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat be lt within six seconds after
the ignition switch is turned to ON

When no one is sitting in th e front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may no t come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them. 2 Protecting Child Passengers P. 62

Safe Driving
The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. Both side
curtain airbags are deployed in a rollover.
The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver's airbag is stored
in the center of the steering wheel; the
front passenger's airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bTwo side airbags, one for the driver and
one for a front passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG.
cTwo side curtain ai rbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG .
dAn electronic control unit that, when the
vehicle is on, continually monitors
information about the various impact
sensors, seat and buckle sensors, rollover
sensor, airbag activators, seat belt
tensioners, and other vehicle
information. During a crash event the
unit can record such information.
eAutomatic front seat belt tensioners. In
addition, the driver's and front
passenger's seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
fA driver's seat position sensor. This
sensor determines the optimal force at
which the airbag will deploy in a crash.
gWeight sensors in the front passenger's
seat. The front passenger's airbag will be
turned off if the weight on the seat is
approximately 65 lbs (29 kg) or less (the
weight of an infant or small child).
hImpact sensors that can detect a
moderate-to-severe front or side impact.
iAn indicator on the dashboard that alerts
you that the front passenger's front
airbag has been turned off.
jAn indicator on the instrument panel that
alerts you to a possib le problem with your

uuAirbags uFront Airbags (SRS)

Safe DrivingFront airbags are designed to inflate du ring moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won't interfere with the driver's visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver's and fr ont passenger's airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.

■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scra pes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move toward the front of the vehicle. Side
airbags and side curtain airbags have been specifically designed to help reduce the
severity of injuries that can occur during a moderate-to-severe side impact which
can cause the driver or passenger to move toward the side of the vehicle.
Rear impacts: Head restraints and seat belts ar e your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seatbelt or, if your vehicle
is equipped with a rollover sensor, both a seatbelt and a side curtain airbag. Front
airbags, however, are not designed to depl oy in a rollover as they would provide
little if any protection.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not depl oy, even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

Safe DrivingThe airbags have advanced features to help reduce the likelihood of airbag related
injuries to smaller occupants.
The driver's advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger's advanced airbag system
has weight sensors.
We advise against allowing a child age 12 or
under to ride in the front passenger's seat.
However, if you do allow a child age 12 or
under to ride in the front passenger's
seat , note that the system will automatically
turn off the front passenger's airbag if the
sensors detect that the child is approximately
65 lbs (29kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver's seat position
sensor, the SRS indicator wi ll come on, and in the
event of a crash, the airbag will deploy (regardless of
the driver's seating position) with a force
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•All occupants should sit upright and wear their seat
belts properly.
•Do not cover the passenger 's side dashboard with
a cloth, towel, cover, etc. 2 Passenger Airbag Off Indicator P. 60

Side Airbags
The side airbags help protect the torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver's and passenger's seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
If the impact is on the passenger's side, the airbag
may not deploy when there is no passenger in the
front passenger seat.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replac ing or covering front seat-back
covers can prevent your si de airbags from properly
deploying during a side impact.

uuAirbags uSide Airbags
Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle's framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag to not deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle's crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.

indicator comes on
The indicator comes on to alert you that the
passenger's front airbag has been turned off.
This occurs when the weight sensors detect
about 65 lbs (29 kg) or less, the weight of an
infant or small child, on the seat.
Children age 12 or under should always ri de properly restrained in a back seat.
2Child Safety P. 62
If the front passenger's seat is empty, the passenger's front airbag will not deploy
and the indicator will come on.
■Passenger Airbag Off Indicator1Passenger Airbag Off Indicator
To ensure the passenger is detected properly, confirm
that:
•There is no child seat or other object pressing
against the rear of the seat-back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.
•The front seat or seat-b ack is not forced back
against an object on the s eat or floor behind it.
•There is no object placed under or beside the front
passenger’s seat.
•The occupant is sitting in an upright position and
the seat back is not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are plac ed on the floor in front
of them.
•There are no objects ha nging from the front
passenger’s seat.
•Only small, lightweight objects are in the seat-back
pocket.
The passenger airbag off indicator may come on and
go off periodically if the tota l weight on the seat is
near the airbag cutoff threshold.
Have your vehicle checked by a dealer as soon as
possible if:
•All of the above conditions are met, and the
indicator comes on with an adult seated in the
front passenger seat.
•The seat is empty and the indicator is off.
Do not allow an adult passe nger to ride in the front
seat when the indicator is on.

Airbag Care
You do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by a dealer in the following situations:
■When the airbags have deployed
If an airbag has inflated, the control unit and other related parts must be replaced.
Similarly, once an automatic seat belt te nsioner has been activated, it must be
replaced.
■When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have yo ur dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, front seat belt
tensioners, and each seat belt that was worn during the crash.
■Do not remove or modify a front seat without consulting a dealer
This would likely disable or affect the proper operation of the driver's seat position
sensor or the weight sensors in the passenge r's seat. If it is necessary to remove or
modify a front seat to accommodate a pe rson with disabilities, contact a Honda
dealer, or for U.S. vehicles, American Ho nda Automobile Customer Service at 1-800-
999-1009 and for Canadian vehicles, Honda Canada Customer Relations at 1-888-
9-HONDA-9.
