■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 not to 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.

Safe Driving■When the passenger airbag off
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 ride properly restrained in a back seat.
2 Child Safety P. 61
If the front passenger’s seat is empty, the indicator will come on and, in the event of
a crash, the front passenger’s airbag will not deploy. The front passenger’s knee
airbag will not deploy either.
■Passenger Front Airbag Off Indicator1 Passenger Front 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, th e 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 vehicl e has been in a moderate-to-severe collision
Even if the airbags did not inflate, have your 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 prop er operation of the driver’s seat position
sensor or the weight sensors in the passenger ’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.
1 Airbag Care
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, reclining child seat until the
infant reaches the seat manufacturer’s weig ht or height limit for the seat, and the
infant is at least one year old.
■Positioning a rear-facing child seat
Child seats must be placed and secured in a
rear seating position.
When properly installed, a rear-facing chil d seat may prevent the driver or a front
passenger from moving their seat all the wa y back, or from locking their seat-back
in the desired position. Make sure that there is no contact between the child seat
and the seat in front of it.
It can also interfere with proper operation of the passenger’s advanced front airbag
system.
2 Airbags P. 45
If this occurs, we recommend that you insta ll 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 smaller rear-facing child seat.
■Protecting Infants1 Protecting Infants
Many experts recommend us e of a rear-facing seat
for a child up to two years ol d if the child’s height and
weight are appropriate for a rear-facing seat.
Rear-facing child seats should never be installed 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.
