2012 Acura MDX Owner's Manual

6. Maintain a Proper Sitting
Position
After all occupants have adjusted
their seats and head restraints, and
put on their seat belts, it is very
important that they continue to sit
upright, well back in their seats, with
their feet on the floor, until the
vehicle is safely parked and the
engine is off.
Sitting improperly can increase the
chance of injury during a crash. For
example, if an occupant slouches, lies
down, turns sideways, sits forward,
leans forward or sideways, or puts
one or both feet up, the chance of
injury during a crash is greatly
increased.In addition, an occupant who is out of
position in the front seat can be
seriously or fatally injured in a crash
by striking interior parts of the
vehicle or being struck by an
inflating front airbag.
Sitting improperly or out of
position can result in serious
injury or death in a crash.
Always sit upright, well back in
the seat, with your feet on the
floor.

Advice for Pregnant WomenIf you are pregnant, the best way to
protect yourself and your unborn
child when driving or riding in a
vehicle is to always wear a seat belt,
and keep the lap part of the belt as
low as possible across the hips.When driving, remember to sit
upright and adjust the seat as far
back as possible while allowing full
control of the vehicle. When riding
as a front passenger, adjust the seat
as far back as possible.This will reduce the risk of injuries to
both you and your unborn child that
can be caused by a crash or an
inflating front airbag.
Each time you have a checkup, ask
your doctor if it's okay for you to
drive.

Driver and Passenger Safety

Additional Safety Precautions●
Never let passengers ride in the
cargo area or on top of a folded-
down back seat.
If they do, they
could be very seriously injured in a
crash.
●
Passengers should not stand up or
change seats while the vehicle is
moving.
A passenger who is not
wearing a seat belt during a crash
or emergency stop can be thrown
against the inside of the vehicle,
against other occupants, or out of
the vehicle.
●
Two people should never use the
same seat belt.
If they do, they
could be very seriously injured in a
crash.
●
Do not put any accessories on seat
belts.
Devices intended to improve
occupant comfort or reposition the
shoulder part of a seat belt can
reduce the protective capability of
the belt and increase the chance of
serious injury in a crash.
●
Do not place hard or sharp objects
between yourself and a front
airbag.
Carrying hard or sharp
objects on your lap, or driving with
a pipe or other sharp object in your
mouth, can result in injuries if your
front airbag inflates.
●
Keep your hands and arms away
from the airbag covers.
If your
hands or arms are close to an
airbag cover, they could be injured
if the airbag inflates.
●
Do not attach or place objects on
the front airbag covers.
Objects on
the covers marked‘‘SRS AIRBAG’’
could interfere with the proper
operation of the airbags or be
propelled inside the vehicle and
hurt someone if the airbags inflate.
●
Do not attach hard objects on or
near a door.
If a side airbag or a
side curtain airbag inflates, a cup
holder or other hard object
attached on or near the door could
be propelled inside the vehicle and
hurt someone.
●
Do not cover or replace front seat-
back covers without consulting
your dealer.
Improperly replacing
or covering front seat-back covers
can prevent your side airbags from
inflating during a side impact.

Seat Belt System Components
Your seat belt system includes lap/
shoulder belts in all seating
positions. The front seat belts are
also equipped with automatic seat
belt tensioners and, on models with
collision mitigation braking system™
(CMBS™), seat belt e-pretensioners.
The seat belt system
includes an indicator on the
instrument panel and a beeper to
remind you and your front passenger
to fasten your seat belts.
This system monitors the front seat
belts. If you turn the ignition switch
to the ON (II) position before your
seat belt is fastened, the beeper will
sound and the indicator will flash. If
your seat belt is not fastened before
the beeper stops, the indicator will
stop flashing but remain on.
If a front passenger does not fasten
their seat belt, the indicator will
come on about 6 seconds after the
ignition switch is turned to the ON
(II) position.If either the driver or a front
passenger does not fasten their seat
belt while driving, the beeper will
sound and the indicator will flash
again at regular intervals.
You will also see a‘‘FASTEN SEAT
BELT’’or‘‘FASTEN PASSENGER
SEAT BELT’’message on the multi-
information display (see page 87).
When no one is sitting in the front
passenger's seat, the indicator
should not come on and the beeper
should not sound. When an infant or
small child is riding there, the
indicator may not come on and the
beeper may not sound.

Driver and Passenger Safety

If the indicator comes on or the
beeper sounds when the driver's seat
belt is latched and there is no front
seat passenger and no items on the
front seat, something may be
interfering with the monitoring
system. 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) touching the rear of
the seat-back.
If no obstructions are found, have
your vehicle checked by a dealer.Lap/Shoulder Belt
The lap/shoulder belt goes over your
shoulder, across your chest, and
across your hips.
To fasten the belt, insert the latch
plate into the buckle, then tug on the
belt to make sure the buckle is
latched (see page 16 for how to
properly position the belt).
To unlock the belt, press the red
PRESS button on the buckle. Guide
the belt across your body so that it
retracts completely. After exiting the
vehicle, be sure the belt is out of the
way and will not get closed in the
door.All seat belts have an emergency
locking retractor. In normal driving,
the retractor lets you move freely in
your seat while it keeps some tension
on the belt. During a collision or
sudden stop, the retractor
automatically locks the belt to help
restrain your body.
The seat belts in all positions except
the driver's have a lockable retractor
that must be activated to secure a
child seat (see page 53).
If the shoulder part of the belt is
pulled all the way out, the lockable
retractor will activate. The belt will
retract, but it will not allow the
passenger to move freely.
To deactivate the lockable retractor,
unlatch the buckle and let the seat
belt fully retract. To refasten the seat
belt, pull it out only as far as needed.
Additional Information About Your Seat Belts22

The lap/shoulder belts in the center
seat of the second row and both of
the third row seats are equipped with
a detachable anchor that has two
parts: a small latch plate and a
buckle.
The detachable seat belt should
normally be latched whenever the
seat-backs are in an upright position.
For more information about the
detachable seat belt, see page 155.
Allowing a child to play with a
seat belt or wrap one around
their neck can result in serious
injury or death.
Instruct children not to play with
any seat belt and make sure
any unused seat belt a child
can reach is buckled, fully
retracted, and locked.Automatic Seat Belt Tensioners
For added protection, the front seat
belts are equipped with automatic
seat belt tensioners. When activated,
the tensioners immediately tighten
the belts to help hold the driver and a
front passenger in position.

Driver and Passenger Safety

The tensioners can be activated
during a collision in which the front
airbags
do not deploy.
In this case, the
airbags would not be needed, but the
extra tension in the seat belt could be
helpful.
If the tensioner is activated, the SRS
indicator comes on and the tensioner
must be replaced.Seat Belt e-pretensioners
On models with Collision Mitigation
Braking System™(CMBS™)For added safety, the front seat belts
are equipped with e-pretensioners
that work in combination with the
collision mitigation braking system™
(CMBS™) (see page 463) and the
brake pedal assist function (see page
460).If your vehicle gets too close to the
vehicle ahead of it in your lane, the
driver's e-pretensioner slightly
retracts the seat belt to alert the
driver of the approaching vehicle. If a
collision with the vehicle in front of
you is likely, the e-pretensioners on
both front seats retract the seat belts
with enough force to properly
restrain you and your front
passenger. After they activate, the e-
pretensioners release the retracted
seat belts.
To get the full benefit of the e-
pretensioners, you and your front
passenger must sit normally in your
seats and wear your seat belts
properly (see page 16).
Additional Information About Your Seat Belts24

If the automatic seat belt tensioners
are activated by a collision, both front
seat belts and all related components
must be replaced (see page 25). If
only the e-pretensioners were
activated, no components need to be
replaced.
In addition, the front passenger's e-
pretensioner does not activate when
the passenger's airbag is
automatically turned off because the
weight sensor detects a child in the
front passenger's seat.Seat Belt Maintenance
For safety, you should check the
condition of your seat belts regularly.
Pull each belt out fully, and look for
frays, cuts, burns, and wear. Check
that the latches work smoothly and
the belts retract easily. If a belt does
not retract easily, cleaning the belt
may correct the problem (see page
534). Any belt that is not in good
condition or working properly will
not provide good protection and
should be replaced as soon as
possible.
Acura provides a limited warranty on
seat belts. See your
Acura Warranty
Information
booklet for details.If a seat belt is worn during a crash,
you should have your dealer inspect
the belt, and replace it if necessary. A
belt that has been worn during a
crash may not provide the same level
of protection in a subsequent crash.
The dealer should also inspect the
anchors for damage and replace
them if needed. If the automatic seat
belt tensioners activate during a
crash, they must be replaced.
