2012 Acura MDX airbag off

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 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 will deploy if
there is no passenger in the front
seat, or if the advanced airbag
system has turned the passenger's
airbag off (see page 37).
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.

The driver's advanced front airbag
system includes a seat position
sensor under the seat. If the seat is
too far forward, the airbag will inflate
with less force, regardless of the
severity of the impact.
If there is a problem with the sensor,
the SRS indicator will come on, and
the airbag will inflate in the normal
manner regardless of the driver's
seating position.
The passenger's advanced front
airbag system has weight sensors
under the seat. Although Acura does
not encourage carrying an infant or
small child in front, if the sensors
detect the weight of an infant or
small child (up to about 65 lbs or 29
kg), the system will automatically
turn the passenger's front airbag off.Be aware that objects placed on the
passenger's seat can also cause the
airbag to be turned off.
When the passenger airbag gets
turned off by the weight sensors, a
‘‘passenger airbag off’’indicator in
the center of the dashboard comes
on (see page 37).
If the weight sensors detect there is
no passenger in the front seat, the
airbag is automatically turned off.
However, the passenger airbag off
indicator in this situation will not
come on.

Only one airbag will deploy during a
side impact. If the impact is on the
passenger's side, the passenger's
side airbag may not deploy if there is
no passenger.
To get the best protection from the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.
Side Airbag Cutoff SystemYour vehicle has a side airbag cutoff
system designed primarily to protect
a child riding in the front passenger's
seat.
Although Acura does not encourage
children to ride in front, if the
position sensors detect a child has
leaned into the side airbag's
deployment path, the airbag will shut
off.
The side airbag may also shut off if a
short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag's
deployment path.
Objects placed on the front
passenger seat can also cause the
side airbag to be shut off.If the side airbag off indicator comes
on (see page 36), have the passenger
sit upright. Once the passenger is
out of the airbag's deployment path,
the system will turn the airbag back
on, and the indicator will go out.
There will be some delay between
the moment the passenger moves
into or out of the airbag deployment
path and when the indicator comes
on or goes off.
A front seat passenger should not
use a cushion or another object as a
backrest. It may prevent the cutoff
system from working properly.

How the SRS Indicator Works
The SRS indicator alerts you
to a potential problem with
your airbag system components.
When you turn the ignition switch to
the ON (II) position, this indicator
comes on briefly then goes off. This
tells you the system is working
properly.
If the indicator comes on at any other
time, or does not come on at all, you
should have the system checked by
your dealer. For example:
●
If the SRS indicator does not come
on after you turn the ignition switch
to the ON (II) position.
●
If the indicator stays on after the
engine starts.
●
If the indicator comes on or flashes
on and off while you drive.You will also see a‘‘CHECK AIRBAG
SYSTEM’’message on the multi-
information display (see page 87).
If you see any of these indications,
the airbag system components may
not work properly when you need
them.
Ignoring the SRS indicator can
result in serious injury or death
if the airbag systems or
tensioners do not work
properly.
Have your vehicle checked by a
dealer as soon as possible if
the SRS indicator alerts you to
a possible problem.How the Side Airbag Off Indicator
Works
U.S. Canada
This indicator
alerts you that the
passenger's side airbag has been
automatically shut off. It does
not
mean there is a problem with your
side airbags.
When you turn the ignition switch to
the ON (II) position, the indicator
should come on briefly and then go
out (see page 70). If it does not come
on, stays on, or comes on while
driving without a passenger in the
front seat, you will also see a
‘‘PASSENGER SIDE AIRBAG OFF’’
message on the multi-information
display. Have the system checked
(see page 87).

How the Passenger Airbag Off
Indicator WorksThis indicator alerts you that the
passenger's front airbag has been
shut off because weight sensors
detect about 65 lbs (29 kg) or less
(the weight of an infant or small
child) on the front passenger's seat.
It does
not mean
there is a problem
with the airbag.Be aware that objects placed on the
front seat can cause the indicator to
come on.
If no weight is detected on the front
seat, the airbag will be automatically
shut off. However, the indicator will
not come on.
The passenger airbag off indicator
may come on and off repeatedly if the
total weight on the seat is near the
airbag cutoff threshold.
If an adult or teenage passenger is
riding in front, move the seat as far to
the rear as possible, and have the
passenger sit upright and wear the
seat belt properly.If the indicator comes on with no
front seat passenger and no objects
on the seat, or with an adult riding
there, something may be interfering
with the weight sensors. Look for
and remove:
●
Any items under the front
passenger's seat.
●
Any object(s) hanging on the seat
or in the seat-back pocket.
●
Any object(s), such as a folded-
down back seat, that are touching
the rear of the seat-back.
If no obstructions are found, have
your vehicle checked by a dealer as
soon as possible.

Additional Safety Precautions●
Do not attempt to deactivate your
airbags.
Together, airbags and seat
belts provide the best protection.
●
Do not tamper with airbag
components or wiring for any
reason.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
●
Do not expose the front
passenger's seat-back to liquid.
If
water or another liquid soaks into
a seat-back, it can prevent the side
airbag cutoff system from working
properly.
●
Do not remove or modify a front
seat without consulting your
dealer.
This could make the
driver's seat position sensor or the
front passenger's weight sensors
ineffective. If it is necessary to
remove or modify a front seat to
accommodate a person with
disabilities, first contact Acura
Client Relations. In the US call 800-
382-2238 and in Canada call 888-9-
ACURA-9.

All Children Should Sit in a Back
Seat
According to crash 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 under certain
circumstances (see page 37), please
follow these guidelines:
Infants
Never put a rear-facing child seat in
the 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 in
the 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 child
seats are also at risk of being injured
or 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 page 57 for important
information about protecting larger
children.)

Child Seat PlacementWe strongly recommend placing a
forward-facing child seat in a back
seat, not the front.Placing a forward-facing child seat in
the front seat of a vehicle equipped
with a passenger's 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 airbag can strike the child
with enough force to cause very
serious or fatal injuries.Even with advanced front airbags
that automatically turn the
passenger's front airbag off (see page
37), a back seat is the safest place for
a small child.
If it is necessary to put a forward-
facing child seat in the front, move
the vehicle seat as far to the rear as
possible, be sure the child seat is
firmly secured to the vehicle and the
child is properly strapped in the seat.
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.
