Quick Reference Guide
Honda Sensing® (P588)
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.
Front Sensor
Camera The camera is located
behind the rearview
mirror.
Radar Sensor
The radar sensor is
in the front grille.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P 591)
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.
Adaptive Cruise Control
(ACC) with Low Speed
Follow
(P602)
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.
Lane Keeping Assist
System (LKAS)
(P 618)
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 627)
Alerts and helps to assist you when the
system detects a possibility of your vehicle
unintentionally crossing over detected lane
markings.
Traffic Sign Recognition
System
(P 632)
Reminds you of road sign information, such
as the current speed limit, your vehicle has
just passed through, showing it on the
driver information interface.

uuSeat Belts uAbout Your Seat Belts
Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching and leaning reduce the effectiveness of the
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat be lts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
The 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 you set the power mode to ON 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.
■Seat Belt Reminder
1About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.
1Seat 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 power mode is set 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 not come on and the
beeper may not sound when the occupant is not
heavy enough to trigger th e 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. 67

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, front passenger’s
knee, front side, and side curtain airbags are
deployed according to the direction and
severity of impact. Both side curtain airbags
are deployed in a ro llover. 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 knee airbags. Th e driver’s knee
airbag is stored under the steering
column; the front passenger’s knee
airbag is stored under the glove box.
Both are marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for the front passenger. The airbags
are stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
dTwo side curtain airbags, 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
.
eAn 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.
fAutomatic 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.
gDriver’s seat position sensor. This sensor
detects the driver’s seat slide position to
help determine the optimal deployment
of the driver’s airbag.
hWeight sensors in the front passenger’s
seat. The sensors are used for occupant
classification to activate or deactivate the
front passenger’s airbag.
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
kAn indicator on the instrument panel that
alerts you to a possib le problem with your
airbag system or seat belt tensioners.
lSafing Sensor
mA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng 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 scrape s, 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 airb ags 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 are your best protection during a rear
impact. Front airbags cannot provide any si gnificant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy 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 deploy, 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.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to he lp 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.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor or the passenger’s s eat weight sensors, the
SRS indicator will come on, and in the event of a
crash, the airbag will deploy (regardless of the driver’s
seating position or passenger’s occupant
classification) with a fo rce corresponding to the
severity of the impact. 2 Supplemental Restraint System (SRS)
Indicator P. 63
For the advanced front airbags to work properly,
confirm that:
•The occupant is sitting in an upright position,
wearing the seat belt prope rly 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 objec ts are in the seat back
pocket.
•The steering wheel and passenger’s side dashboard
are not obstructed by any object.
•No liquid has been spille d on or under the seat.•There is no child seat or other object pressing
against the rear of the seat or seat back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.

The front passenger’s ad vanced airbag system
has weight sensors. The sensors are used for
occupant classification to activate or
deactivate the front passenger’s airbag.
For adult size occupants, the system will
automatically activate the front passenger’s
airbag. If a small adult sits in the front
passenger seat and the system does not
recognize him/her as an adult, see
2Passenger Front Airbag Off Indicator P. 64
We advise against allowing a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a small child or
infant to ride in the front passenger’s seat, the
system is designed to automatically deactivate
the front passenger’s airbag. Do not let a
small child or infant ride in the front
passenger’s seat if the airbag does not
automatically deactivate.
