2003 Acura MDX sensor

Devices intended to improve
occupant comf ort or reposition the
shoulder part of a seat belt can
severely compromise the
protective capability of the seat
belt and increase the chance of
serious injury in a crash.
Carrying hard or sharp
objects on your lap, or driving with
a pipe or other sharp objects in
your mouth, can result in injuries
if your f ront airbag inf lates. If a side airbag
inflates,acupholderorotherhard
object attached on or near the
door could be propelled inside the
car and hurt someone.
If your
hands or arms are close to the
airbag covers in the center of the
steering wheel and on top of the
dashboard, they could be injured if
the airbags inf late.
Any object
attached to or placed on the covers
marked ‘‘SRS AIRBAG’’ in the
center of the steering wheel and
on top of the dashboard could
interf ere with the proper operation
of the airbags. Or, if the airbags
inf late, the objects could be
propelled inside the car and hurt
someone. This could make the driver’s seat
position sensor or the f ront
passenger’s seat weight sensors
inef f ective.
This could cause
problems with the driver’s seat
position sensor or the f ront
passenger’s seat weight sensors.
Do not put any accessories on seat
belts.
Do not place hard or sharp object sbet ween yourself and a f rontairbag. Do not at t ach hard object s on or
near a f ront door.

Do not at t ach or place object s onthe f ront airbag covers. Do not modif y t he f ront seat s.
Do not place any it ems under t hefront seats.
Protecting Adults
Driver and Passenger Saf ety20

Front airbags have been designed to
help protect adults in a moderate to
severe f rontal collision. To do this,
the passenger’s f ront airbag is quite
large, and it can inflate with enough
f orce to cause very serious injuries.With an advanced airbag system, the
f ront passenger’s airbag is turned of f
if sensors detect a total weight of
less than about 65 lbs (30 kg) in the
seat, and the ‘‘Passenger Airbag
Cutof f ’’ indicator is turned on. (See
page f or additional inf ormation on
how the passenger’s airbag works.)
Even if the passenger’s f ront airbag
is turned of f , we strongly
recommend that inf ants, small
children, and larger children ride
properly restrained in a back seat
wheretheywillbesafer.
To help prevent airbag-caused
deaths and injuries to children, this
vehicle has an advanced airbag
system. 58

Af ter inf lating, the f ront airbags
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.
The total time for inflation and
def lation is approximately one-tenth
of a second, so f ast that most
occupants are not aware that the
airbags deployed until they see them
lying in their laps.
Since both airbags use the same
sensors, both airbags normally
inf late at the same time. However, it
is possible f or only one airbag to
inf late.
This can occur when 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.
During a f rontal crash, your seat
belts help restrain your lower body
and torso. Your airbag provides a
cushion to help restrain and protect
your head and chest. If you ever have a moderate to
severe f rontal collision, the sensors
will detect the vehicle’s rapid
deceleration. If the rate of
deceleration is high enough, the
control unit will instantly inf late the
f ront airbags.

After a crash, you may see what
looks like smoke. This is actually
powder f rom the airbag’s surf ace.
Although the powder is not harmf ul,
people with respiratory problems
mayexperiencesometemporary
discomf ort. If this occurs, get out of
the vehicle as soon as it is saf e to do
so.Your vehicle has a driver’s seat
position sensor as a part of the
advanced airbag system. The sensor
is located on the inside of the lef t
seat rail under the driver’s seat. This
sensor monitors the driver’s seat
sliding position and sends the
inf ormation to control unit. The
control unit will control adequate
inf lation and timing of the driver’s
airbag.
Do not put any cargo or metal
objects under the driver’s seat, and
do not cover the sensor with
anything, including the rear seat
passenger’s f eet.
This will cause the sensor to work
improperly and will damage it.If there is a problem in the sensor,
the SRS indicator in the instrument
panel comes on. In this case, the
driver’s airbag will inf late normally
during a crash regardless of the
driver’s seating position.

Your vehicle has front passenger’s
weightsensorsaspartof the
advanced airbag system. They are
located under both of the f ront
passenger’s seat rails. These sensors
monitor the weight on the seat at the
seat cushion, seat-back, seat-back
pocket, and seat rails.
If the total weight on the seat is
about65lbs(30kg)orless,the
system shuts of f the f ront passenger’s

you that the f ront passenger’s airbag
will not inf late during a crash.
If there is no passenger in the f ront

Your vehicle is equipped with side
airbags f or the driver and a f ront
seat passenger. The airbags are
stored in the outer edges of the f ront
seat-backs, and both are marked
‘‘SIDE AIRBAG.’’If you ever have a moderate to
severe side impact, the 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.
