2009 Acura RL belt

If a seat belt is worn during a crash,
it must be replaced by the dealer. 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 f or damage and replace
them if needed. If the automatic seat
belt tensioners activate during a
crash, they must be replaced.
For saf ety, you should check the
condition of your seat belts regularly.
Pull each belt out f ully, and look f or
f rays, 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
). 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 booklet f or details.

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.
The total time for inflation and
def lation is 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.
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 will deploy if
there is no passenger in the f ront
seat, or if the advanced airbag
system has turned the passenger’s
airbag off (see page ).

Your f ront airbags are also dual-
threshold airbags. Airbags with this
f eature have two deployment
thresholds that depend on whether
sensors detect the occupant is
wearing a seat belt or not.
If the occupant’s belt is ,
the airbag will deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
Your f ront airbags are dual-stage
airbags. This means they have two
inf lation stages that can be ignited
sequentially or simultaneously,
depending on crash severity.
In a crash, both stages
will ignite simultaneously to provide
the quickest and greatest protection.
In a crash, one stage will
ignite first, then the second stage
will ignite a split second later. This
provides longer airbag inf lation time
with a little less force.
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.
If the occupant’s belt is , the
airbag will inf late at a slightly higher
threshold, when the airbag would be
needed to supplement the protection
provided by the seat belt.

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.
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. 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
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.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 (up to about 65 lbs or 29
kg), the system will automatically
turn the passenger’s front airbag off.
Do not spill any liquids on or
under the seats, cover the sensors,
or put any objects or metal items
under the f ront seats.
Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.

There will be some delay between

pathandwhentheindicatorcomes

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.
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.
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.
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
position sensors detect a child has
leaned into the side airbag’s
deployment path, the airbag will shut
off.

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.
To get the best protection f rom the
side curtain airbags, occupants
should wear their seat belts and sit

If the SRS indicator does not come
on after you turn the ignition
switch to the ON (II) position.
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:
In 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 driver’s or the
passenger’s side of the vehicle. When you turn the ignition switch to
the ON (II) position, this indicator
comes on brief ly then goes of f . This
tells you the system is working
properly.
The SRS indicator alerts you to a
potential problem with your airbags,
seat belt tensioners, and, on models
with CMBS, seat belt e-pretensioners.
