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 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 pers on with disabilities, contact an Acura 
dealer, or for U.S. vehicles, Acura Clie nt Relations at 1-800-382-2238 and for 
Canadian vehicles, Acura Client  Services at 1-888-9-ACURA-9.
1Airbag Care
We recommend against the use of salvaged airbag 
system components, includi ng the airbag, tensioners, 
sensors, and control unit.

uuChild Safety uSafety of Infants and Small Children
Safe Driving
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 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. 47
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
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.
