■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 front 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. 55
Objects placed on the seat can also cause the indicator to come on.
If the front passenger’s seat is empty, th e passenger’s front airbag will not deploy
and the indicator will not come on.
■Passenger Front Airbag Off Indicator1 Passenger Front Airbag Off Indicator
If the indicator comes on wi th no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors, such as:
•An object hanging on the seat or in the seat-back
pocket.
•A child seat or other obj ect pressing against the
rear of the seat-back.
•A rear passenger pushing or pulling on the back of
the front passe nger’s seat.
•The front seat or seat-back is forced back against
an object on the seat or floor behind it.
•An object placed under th e front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger front airbag off indicator may come
on and go off repeat edly if the total weight on the
seat is near the airbag cutoff threshold.

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 tensioner 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 proper 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 person with disabilities, contact a Honda
dealer, or for U.S. vehicles, American Honda Automob ile 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. 42
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 old 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.
