Safety Checklist
For the safety of you and your passengers, make a habit of checking these items
each time before you drive.
• After everyone has entered the vehicle, be sure all doors are closed and locked.
Locking the doors helps prevent an occupant from being ejected and an outsider
from unexpectedly opening a door.
2 Locking/Unlocking the Doors from the Inside P. 177
•Adjust your seat to a position suitable for driving. Be sure the front seats are
adjusted as far to the rear as possible while allowing the driver to control the
vehicle. Sitting too close to a front airbag can result in serious or fatal injury in a
crash.
2 Seats P. 212
•Adjust head restraints to the proper position. Head restraints are most effective
when the center of the head restraint aligns with the center of your head. Taller
persons should adjust their head restraint to the highest position.
2 Adjusting the Front and Rear Outer* Head Restraint Positions P. 219
•Always wear your seat belt, and make sure you wear it properly. Confirm that any
passengers are properly belted as well.
2 Fastening a Seat Belt P. 42
•Protect children by using seat belts or child seats according to a child’s age, height
and weight.
2 Child Safety P. 64
1Safety Checklist
If the door and/or trunk open message appears on
the driver information inte rface, a door and/or the
trunk is not completely cl osed. Close all doors and
the trunk tightly until the message disappears.

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.
■Front seats
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
1 About Your Seat Belts
Most states and all Canadian provinces and territories
require you to w ear seat belts.
1Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat belt 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 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. 64

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.
■Advanced Airbags1Advanced 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

1Passenger Front Airbag Off Indicator
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. For a small adult,
depending on physique and posture, the system may
not recognize him/her as an adult and thus deactivate
the front passenger’s airbag.
If this occurs, please confirm that the conditions set
forth in the above bullet points on the previous page
are met.
If the above conditions are met and the indicator is
still on, then with the transmission in
( P, set the
power mode to OFF and back to ON.
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 Honda Automobile Customer Service at
1-800-999-1009 and for Canadian vehicles, Honda Canada Customer Relations at
1-888-9-HONDA-9.

We recommend against the use of salvaged airbag
system components, includi ng the airbag, tensioners,
sensors, and control unit.

Safety of Infants and Small Children
An infant must be properly restrained in a rear-facing child seat until the infant
reaches the seat manufacturer’s weig ht or height limit for the seat.
■Positioning a rear-facing child seat
Child seats must be placed and secured in a
rear seating position.
When properly installed, a rear-facing child seat may prevent the driver or a front
passenger from moving their seat all the way back, or from locking their seat-back
in the desired position. Make sure that th ere is no contact between the child seat
and the seat in front of it.
It can also interfere with pr oper operation of the passenger’s advanced front airbag
system.
2 Airbags P. 46
If this occurs, we recommend that you install the child seat directly behind the front
passenger’s seat, move the seat as far fo rward as needed, and leave it unoccupied.
Or, you may wish to get a sm aller rear-facing child seat.
■Protecting Infants1Protecting Infants
Experts recommend use of a rear-facing seat for a
child so long as the child’ s height and weight are
appropriate for a rear-facing seat.
Infants should never be s eated in a forward-facing
position.
Always refer to the child seat manufacturer’s
instructions before installation.
Do not allow a front seat to rest against a child seat
installed in a rear seating position:
The weight sensor in the fr ont seat may not correctly
detect the actual weight of the occupant.
3WARNING
Placing a rear-facing child seat in the front
seat can result in serious injury or death
during a crash.
Always place a rear-fac ing child seat in the
rear seat, not the front.

Continued67
uuChild Safety uSafety of Infants and Small Children
Safe DrivingIf a child has exceeded the weight and hei ght limitations of a rearward-facing child
seat, the child should be properly restrain ed in a firmly secured forward-facing child
seat until they exceed the we ight and height limitations for the forward-facing child
seat.
■Forward-facing child seat placement
We strongly recommend placing a forward-
facing child seat in a rear seating position.
Placing a forward-facing child seat in th e front seat can be hazardous, even with
advanced front airbags that automatically turn the passeng er’s front airbag off. A
rear seat is the safest place for a child.
■Protecting Smaller Children1 Protecting Smaller Children
Educate yourself about th e laws and regulations
regarding child seat use wh ere you are driving, and
follow the child seat manufacturer’s instructions.
3WARNING
Placing a forward-facing child seat in the
front seat can result in serious injury or
death if the front airbag inflates.
If you must place a forward-facing child
seat in front, move the vehicle seat as far
back as possible, and properly restrain the
child.
