2012 Acura MDX sensor

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.
●
Second-row seat passenger should
not wedge objects or intentionally
force their feet under the front
passenger seat.Also, make sure the floor mat behind
the front passenger's seat is hooked
to the floor mat anchor (see page
535). 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.

Driver and Passenger Safety

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 Your Side Curtain Airbags
WorkIn a Side ImpactIn a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag and activate the seat belt
tensioner on the impacted side of the
vehicle.If the impact is on the passenger's
side, the passenger's side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle.
In a RolloverIf the rollover sensor detects your
vehicle is about to roll over, it signals
the control unit, which immediately
deploys both side curtain airbags and
activates both front seat belt
tensioners.
The airbag on the passenger's side
will deploy even if there are no
passengers on that side of the
vehicle.
To get the best protection from the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.

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.

Airbag Service
Your airbag systems are virtually
maintenance free, and there are no
parts you can safely service.
However, you must have your
vehicle serviced if:●
An airbag ever inflates.
Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. Any
seat belt tensioner that activates
must also be replaced.
We recommend against the use of
salvaged airbag system
components, including the airbag,
tensioners, sensors, and control
unit.
Do not try to remove or replace
any airbag by yourself. This must
be done by an authorized dealer or
a knowledgeable body shop.
●
The SRS indicator alerts you to a
problem.
Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.
●
If your vehicle has a moderate to
severe impact.
Even if your airbags
do not inflate, your dealer should
inspect the driver's seat position
sensor, the front passenger's
weight sensors, the front seat belt
tensioners, and all seat belts and
their anchors worn during a crash
to make sure they are operating
properly.

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.

Instruments and Controls

When you reset Trip A, average fuel
economy A is reset at the same time.
When you reset Trip B, average fuel
economy B is reset.
In the customizing mode, you can set
Trip A and average fuel economy A
to reset at the same time when you
refuel your vehicle (see page 102).Outside Temperature
This shows the outside Fahrenheit
temperature in U.S. models, and
Celsius temperature in Canadian
models.The temperature sensor is in the
front bumper. The temperature
reading can be affected by heat
reflection from the road surface,
engine heat, and the exhaust from
surrounding traffic. This can cause
an incorrect temperature reading
when your vehicle speed is under 19
mph (30 km/h). When you start your
trip, the sensor is not fully
acclimatized, therefore it may take
several minutes until the proper
temperature is displayed.
In certain weather conditions,
temperature readings near freezing
(32°F, 0°C) could mean that ice is
forming on the road surface.
You can adjust the outside
temperature display (see page 101).
