Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching an d leaning reduces the effectiveness of
the belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• 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 the seat belts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the ignition switch is turned to ON
(w
before
the driver’s seat belt is fastened, a beeper will
sound and the indicator will blink. If the driver
does not fasten the belt before the beeper
stops, the indicator will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver’s and front passenger’s seat belts are
fastened.

Seat Belt Reminder
1 About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.1 Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat belt within 6 seconds after
the ignition switch is turned to ON
(w
.
When no one is sitting in the front passenger’s seat,
or a child or small adult is riding there, the indicator
will not come on.
This is because the weight sensors in the seat cannot
detect their presence.

uuAirbags uAirbag System Components
Safe Driving
The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. The airbag
system includes:a
Two SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
front passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
b
Two side airbags, one for the driver and
one for a front passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
c
Two side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
d
An electronic control unit that continually
monitors and records information about
the sensors, the airbag activators, the
seat belt tensioners, and driver and front
passenger seat belt use when the ignition
switch is in ON
(w
.
e
Automatic front seat belt tensioners. The
driver’s and front passenger’s seat belts
incorporate sensors that detect whether
or not they are fastened.
f
A driver’s seat position sensor. If the seat
is too far forward, the airbag will inflate
with less force.
g
Weight sensors in the front passenger’s
seat. The front passenger’s airbag will be
turned off if the weight on the seat is 65
lbs (29 kg) or less (the weight of an infant
or small child).
h
Impact sensors that can detect a
moderate-to-severe front or side
collision.
i
An indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
j
Sensors that can detect if a child or small
statured adult is in the deployment path
of the front passenger’s side airbag.
k
An indicator on the instrument panel that
alerts you to a possible problem with your
airbag system or seat belt tensioners.
l
An indicator on the instrument panel that
alerts you that the front passenger’s side
airbag has been turned off.

uuAirbags uFront Airbags (SRS)
Safe Driving
Your front airbags have advanced features to help reduce the likelihood of airbag
related injuries to smaller occupants.
The driver’s advanced front airbag system
includes a seat position sensor.
If the seat is too far forward, the airbag
inflates with less force, regardless of the
severity of the impact.
The passenger’s advanced front airbag system
has weight sensors.
Although Acura recommends against carrying
an infant or small child in front, if the sensors
detect the weight of a child (up to about 65
lbs or 29 kg), the system will automatically
turn off the passenger’s front airbag.■
Advanced Airbags
1Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator will come on and the airbag
will inflate with full (nor mal) force, regardless of the
driver’s seating position.
For both advanced front airbags to work properly:•Do not spill any liquid on or under the seats.•Do not put any object under the passenger’s seat.•Make sure any objects are positioned properly on
the floor. Improperly positioned objects can
interfere with the advanced airbag sensors.•All occupants should sit upright and wear their seat
belts properly.•Do not place any cover over the passenger side
dashboard.

Safe Driving
Airbag CareYou do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by a dealer in the following situations:■
When the airbags have deployed
If an airbag has inflated, the control unit and other related parts must be replaced.
Similarly, once an automatic seat belt tensioner has been activated, it must be
replaced.
■
When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have your dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, front seat belt
tensioners, and each seat belt that was worn during the crash.
■
Do not remove or modify a front seat without consulting a dealer
This would likely disable the driver’s seat position sensor or the weight sensors in the
passenger’s seat. If it is necessary to remove or modify a front seat to accommodate
a person with disabilities, contact an Acura dealer, or for U.S. vehicles, Acura Client
Relations at 1-800-382-2238 and for Canadian vehicles, Canadian Acura Client
Service at 1-888-9-ACURA-9.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.
