How Your Front Airbags WorkIf you ever have a moderate to severe
frontal collision, sensors will detect
the vehicle's rapid deceleration.
If the rate of deceleration is high
enough, the control unit will instantly
inflate the driver's and front
passenger's airbags, at the time and
with the force needed.During a frontal crash, your seat belt
restrains your lower body and torso,
and the front airbag helps protect
your head and chest.
Although both airbags normally
inflate within a split 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 protection, and the
supplemental protection offered by
the airbag would be minimal.
Only the driver's airbag can deploy if
there is no passenger in the front
seat, or if the advanced airbag
system has turned the passenger's
airbag off (see page34).
After inflating, the front airbags
immediately deflate, so they won't
interfere with the driver's visibility,
or the ability to steer or operate other
controls.

Be aware that objects placed on the
passenger's seat can also cause the
airbag to be turned off.
When the airbag is turned off, a
‘‘passenger airbag off ’’indicator in
the center of the dashboard comes
on (see page34).
If the weight sensors detect there is
no passenger in the front seat, the
airbag will be off. However, the
passenger airbag off indicator will
not come on.
To ensure that the passenger's
advanced front airbag system will
work properly,
do not do anything
that would increase or decrease the weight on the front passenger's seat.
This includes:●A second-row passenger pushing
or pulling on the back of the front
passenger's seat.
●Moving the front seat forcibly back
against cargo on the seat or floor
behind it.●Hanging heavy items on the front
passenger seat, or placing heavy
items in the seat-back pocket.●Moving the front passenger's seat
or seat-back forcibly back against
the folded right-side second-row
seat.
Also, make sure the floor mat behind
the front passenger's seat is hooked
to the floor mat anchor (see page
410).If it is not, the mat may
interfere with the proper operation of
the sensors and operation of the seat. How Your Side Airbags Work
If you ever have a moderate to severe
side impact, sensors will detect rapid
acceleration and signal the control
unit to instantly inflate either the
driver's or the passenger's side
airbag and activate the seat belt
tensioner on the affected side.

All Children Should Sit in a Back
Seat
According to accident statistics,
children of all ages and sizes are
safer when they are restrained in a
back seat.
The National Highway Traffic Safety
Administration and Transport
Canada recommend that all children
aged 12 and under be properly
restrained in a back seat. Some
states have laws restricting where
children may ride.
Children who ride in the back are
less likely to be injured by striking
interior vehicle parts during a
collision or hard braking. Also,
children cannot be injured by an
inflating front airbag when they ride
in the back.The Passenger's Front Airbag Can
Pose Serious Risks
Front airbags have been designed to
help protect adults in a moderate to
severe frontal collision. To do this,
the passenger's front airbag is quite
large, and it can inflate with enough
force to cause very serious injuries.
Even though your vehicle has an
advanced front airbag system that
automatically turns the passenger's
front airbag off (see page34),please
follow these guidelines:
Infants
Never put a rear-facing child seat inthe front seat of a vehicle equipped
with a passenger's front airbag.
If the
airbag inflates, it can hit the back of
the child seat with enough force to
kill or very seriously injure an infant.
Small Children
Placing a forward-facing child seat inthe front seat of a vehicle equipped
with a passenger's front airbag can be
hazardous.
If the vehicle seat is too
far forward, or the child's head is
thrown forward during a collision, an
inflating front airbag can strike the
child with enough force to kill or
very seriously injure a small child.
Larger Children
Children who have outgrown childseats are also at risk of being injuredor killed by an inflating passenger's
front airbag.
Whenever possible,
larger children should sit in the back
seat, on a booster seat if needed, and
be properly restrained with a seat
belt. (See page54for important
information about protecting larger
children.)
Protecting Children －General Guidelines3808/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu
2009 MDX

Protecting InfantsChild Seat TypeAn infant must be properly restrained
in a rear-facing, reclining child seat
until the child reaches the seat
maker's weight or height limit for the
seat, and the child is at least one year
old.
Only a rear-facing child seat provides
proper support for a baby's head,
neck, and back.Two types of seats may be used: a
seat designed exclusively for infants,
or a convertible seat used in the rear-
facing, reclining mode.
Do not put a rear-facing child seat in
a forward-facing position.
If placed
facing forward, an infant could be
very seriously injured during a
frontal collision.
Rear-facing Child Seat PlacementA rear-facing child seat can be placed
in any seating position in the back
seat, but not in the front.
Never put a
rear-facing child seat in the front seat.
If the passenger's front airbag
inflates, it can hit the back of the
child seat with enough force to kill or
seriously injure an infant.
When properly installed in the
second row, a rear-facing child seat
may prevent the driver or a front
passenger from moving their seat as
far back as recommended, or from
locking their seat-back in the desired
position.
It can also interfere with proper
operation of the passenger's
advanced front airbag system.

If a child who uses a booster seat
must ride in front, move the vehicle
seat as far back as possible and be
sure the child is wearing the seat belt
properly.
A child may continue using a booster
seat until the tops of their ears are
even with the top of the vehicle's or
booster's seat-back. A child of this
height should be tall enough to use
the lap/shoulder belt without a
booster seat.When Can a Larger Child Sit in
Front
The National Highway Traffic Safety
Administration and Transport
Canada recommend that all children
age 12 and under be properly
restrained in a back seat.
If the passenger's front airbag
inflates in a moderate to severe
frontal collision, the airbag can cause
serious injuries to a child who is
unrestrained, improperly restrained,
sitting too close to the airbag, or out
of position.
A side airbag also poses risks. If any
part of a larger child's body is in the
path of a deploying side airbag, the
child could receive possibly serious
injuries.Of course, children vary widely. And
while age may be one indicator of
when a child can safely ride in front,
there are other important factors you
should consider.
Physical SizePhysically, a child must be large
enough for the lap/shoulder belt to
properly fit (see pages15and54).If
the seat belt does not fit properly,
with or without the child sitting on a
booster seat, the child should not sit
in front.MaturityTo safely ride in front, a child must
be able to follow the rules, including
sitting properly, and wearing the seat
belt properly throughout a ride.
