■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 and leaning reduce 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 power mode is set to ON before the
driver’s seat belt is fastened, the 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
1About 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.1Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat belt within six seconds after
the power mode is set to ON.
When no one is sitting in the front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may not come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them.

The front, driver’s knee, front side, and side

the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:aTwo SRS (Supplemental Restraint System)

in the center of the steering wheel; the

dashboard. Both are marked SRS

uuAirbagsuFront 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 (normal) 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.
Make sure the floor mat behind the front passenger’s
seat is hooked to the floor mat anchor. An improperly
placed mat can interfere with the advanced airbag
sensors.

■When the passenger airbag off
indicator comes on
The indicator comes on to alert you that the
passenger’s front airbag has been turned off.
This occurs when the front passenger’s weight
sensors detect 65 lbs (29 kg) or less, the
weight of an infant or small child, on the seat.
Infants and small children should always ride properly restrained in a back seat.
2Child Safety P. 54Objects placed on the seat can also cause the indicator to come on.
If the front passenger seat is empty, the passenger’s front airbag will not deploy and
the indicator will not come on.■Passenger Airbag Off Indicator
1Passenger Airbag Off Indicator
If the indicator comes on with no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors. Such as:•An object hanging on the seat or in the seat-back
pocket.•A child seat or other object pressing against the
rear of the seat-back.•A rear passenger pushing or pulling on the back of
the front passenger’s seat.•The front seat or seat-back is forced back against
an object on the seat or floor behind it.•An object placed under the front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger airbag off indicator may come on and
goes off repeatedly if the total weight on the seat is
near the airbag cutoff threshold.

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. For U.S. vehicles, Acura Client
Service at 800-382-2238 and for Canadian vehicles, Acura Client Service at 888-9-
ACURA-9.
1Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.

1Folding Down the Second Row Seat
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly.
2Passenger Airbag Off Indicator P. 52
The front seats must be far enough forward so they
do not interfere with the second row seats as they
fold down.
To lock the seat-back upright, push it backwards until
it locks.
Make sure the seat-back, head restraints and seat
cushion are securely latched back into place before
driving. Also, make sure all rear shoulder belts are
positioned in front of the seat-back, and the center
shoulder belt is re-positioned in the holding slot.
