sensor Acura MDX 2005 Owner's Manual

The seat belts in all seating positions
except the driver’s have an additional
locking mechanism that must be
activated to secure a child seat (see
page ).
If the shoulder part of the belt is
pulled all the way out, the locking
mechanism will activate. The belt
will retract, but it will not allow the
passenger to move f reely.
To deactivate the locking
mechanism, unlatch the buckle and
let the seat belt f ully retract. To
ref asten the belt, pull it out only as
f ar as needed.For added protection, the f ront seat
belts are equipped with automatic
seat belt tensioners. When activated,
the tensioners immediately tighten
the belts to help hold the driver and
a f ront passenger in place.
The tensioners are designed to
activate in any collision severe
enough to cause the f ront airbags to
deploy, or if a sensor detects your
vehicle is about to rollover (see page
). If a side curtain airbag deploys
during a side impact, the tensioner
on that side of the vehicle will also
deploy.
The tensioners can also be activated
during a collision in which the f ront
airbags
. In this case, the
airbags would not be needed, but the
additional restraint could be helpf ul.
When the tensioners are activated,
the seat belts will remain tight until
they are unbuckled in the normal
manner.
If the f ront seat belt tensioners ever
activate, they must be replaced as
the belts will no longer retract
properly.

Your Airbag System (SRS) includes:Two SRS (Supplemental Restraint

the steering wheel; the f ront
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG’’ (see page ).
Two side curtain airbags, one f or
each side of the vehicle. The
airbags are stored in the f ront and
rear pillars and above the windows.
The f ront and rear pillars on both
sides are marked ‘‘SIDE
CURTAIN AIRBAG’’ (see page ).
Two side airbags, one f or the
driver and one f or a f ront

Af ter inf lating, the f ront airbags will
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.
During a f rontal crash, your seat belt
restrains your lower body and torso,
and the f ront airbag helps protect
your head and chest.
Although both airbags normally
inf late within a split second of each
other, it is possible f or 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
suf f icient protection, and the
supplemental protection of f ered by
the airbag would be minimal.
If you ever have a moderate to
severe f rontal collision, sensors will
detect the vehicle’s rapid
deceleration.
If the rate of deceleration is high
enough, the control unit will instantly
inf late the driver’s and f ront
passenger’s airbags, at the time and
with the f orce needed. Only the driver’s airbag can deploy if
the advanced airbag system has
turned the passenger’s airbag of f
(see page ).

The passenger’s advanced f ront
airbag system has weight sensors
under the seat. Although Acura does
not encourage carrying an inf ant or
small child in f ront, if the sensors
detect the weight of an inf ant or
small child, the system will
automatically turn the passenger’s
front airbag off.
The driver’s advanced front airbag
system includes a seat position
sensor under the seat. If the seat is
positioned too f ar f orward, the
airbag will inf late with less f orce,
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 inf late in the normal
manner regardless of the driver’s
seating position.
Your f ront airbags are also advanced
airbags. The main purpose of this
feature is to help prevent airbag-
caused injuries to short drivers and
children who ride in f ront.
For both advanced airbags to work
properly:
Occupants must sit upright and
wear their seat belts properly.
Do not spill any liquids on or
under the seats, cover the sensors,
or put any cargo or metal objects
under the f ront seats.
Back-seat passengers should not
put their f eet under the f ront seats.
Failure to f ollow these instructions
could damage the sensors or prevent
them f rom working properly.

When the airbag is turned of f , an
indicator in the center of the
dashboard will come on indicating
passenger airbag ‘‘OFF’’ (see page).
If there is no passenger in the f ront
seat, the airbag will be off. However,
the Passenger Airbag Of f indicator
will not come on.
Objects placed on the f ront
passenger seat can also cause the
passenger airbag to be shut of f .
To ensure that the passenger’s
advanced front airbag system will
work properly,
This includes: A rear passenger pushing or
pulling on the back of the
passenger’s seat. Moving the f ront seat f orcibly
back against cargo on the seat or
f loor behind it.
Hanging heavy items on the f ront
passenger seat, or placing heavy
items in the seat-back pocket.
If you ever have a moderate to
severe side impact, sensors will
detect rapid deceleration and signal
the control unit to instantly inf late
either the driver’s or the passenger’s
side airbag.

Only one airbag will deploy during a
side impact. If the impact is on the
passenger’s side, the passenger’s
side airbag will deploy even if there
is no passenger.
To get the best protection f rom the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.Your vehicle has a side airbag cutof f
system designed primarily to protect
a child riding in the f ront passenger’s
seat.
Although Acura does not encourage
children to ride in f ront, if the height
and position sensors in the seat
detect a child has leaned into the
side airbag’s deployment path, the
airbag will shut off.If the Side Airbag Of f Indicator
comes on (see page ), 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
pathandwhentheindicatorcomes
on or goes of f .
A f ront seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutof f
system f rom working properly.32

In a moderate to severe side impact,
sensors will detect rapid deceleration
and signal the control unit to
instantly inflate the side curtain
airbag on the driver’s or the
passenger’s 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.
If the rollover sensor detects your
vehicle is about roll over, the control
unit will instantly deploy both side
curtain airbags.
To get the best protection f rom the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
