Your vehicle is equipped with many
features that work together to
protect you and your passengers
during a crash.
However, you and your passengers
can’t take full advantage of these
f eatures unless you remain sitting in
the correct position and
. In fact, some safety
f eatures can contribute to injuries if
they are not used properly.
The f ollowing pages explain how you
cantakeanactiveroleinprotecting
yourself and your passengers. Some f eatures do not require any
action on your part. These include a
strong steel f ramework that f orms a
saf ety cage around the passenger
compartment, front and rear crush
zones, a collapsible steering column,
and tensioners that tighten the f ront
seat belts in a crash.

For added saf ety, the f ront seat belts
are equipped with e-pretensioners
that work in combination with the
collision mitigation braking system
(CMBS ) (see page ) and the
brake pedal assist f unction (see page
).If your vehicle gets too close to the
vehicle ahead of it in your lane, the
driver’s e-pretensioner slightly
retracts the seat belt to alert the
driver of the approaching vehicle. If
a collision with the vehicle in f ront of
you is likely, the e-pretensioners on
both front seats retract the seat belts
with enough f orce to properly
restrain you and your f ront
passenger. After they activate, the
e-pretensioners release the retracted
seat belts.
To get the f ull benef it of the
e-pretensioners, you and your f ront
passenger must sit normally in your
seats and wear your seat belts
properly (see page ).The e-pretensioners do not activate
when the vehicle stability assist
(VSA) of f indicator on the
instrument panel is on.
If the automatic seat belt tensioners
are activated by a collision, both
f ront seat belts and all related
components must be replaced (see
page ). If only the
e-pretensioners were activated, no
components need to be replaced.
In addition, the f ront passenger’s
e-pretensioner does not activate
when the passenger’s airbag is
automatically turned off because the
weight sensor detects a child in the
f ront passenger’s seat. 17

Your airbag system includes:
Two SRS (supplemental restraint
system) f ront airbags. The driver’s
airbag is stored in the center of
the steering wheel; the f ront
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG’’ (see page ).
Two side airbags, one f or the
driver and one f or a f ront
passenger. The airbags are stored
in the outer edges of the seat-
backs. Both are marked ‘‘SIDE
AIRBAG’’ (see page ).
Two side curtain airbags, one f or
each side of the vehicle. The
airbags are stored in the ceiling,
above the side windows. The f ront
and rear pillars are marked ‘‘SIDE
CURTAIN AIRBAG’’ (see page
).A driver’s seat position sensor that
monitors the distance of the seat
from the front airbag. If the seat is
too far forward, the airbag will
inf late with less f orce (see page
).
Weight sensors that monitor the
weight on the f ront passenger’s
seat. If the weight is about 65 lbs
(29 kg) or less (the weight of an
inf ant or small child), the
passenger’s f ront airbag will be
turned of f (see page ).
A sophisticated electronic system
that continually monitors and
records inf ormation about the
sensors, the control unit, the
airbag activators, the seat belt
tensioners, and driver and f ront
passenger seat belt use when the
ignition switch is in the ON (II)
position. On models with CMBS , f ront
seat belt e-pretensioners (see page
).
Automatic front seat belt
tensioners (see page ).
Sensors that can detect a
moderate to severe front impact or
side impact.
Sensors that can detect whether a
child is in the passenger’s side
airbag path and signal the control
unit to turn the airbag of f (see
page ).
Sensors that can detect whether
the driver’s seat belt and the f ront
passenger’s seat belt are latched
or unlatched (see page ). 28

An indicator on the instrument
panel that alerts you to a possible
problem with your airbag system
components (see page ).
An indicator on the instrument
panel that alerts you that the
passenger’s side airbag has been
turned of f (see page ).
An indicator on the dashboard that
alerts you that the passenger’s
f ront airbag has been turned of f

Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.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.
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 ). If the rate of deceleration is high
enough, the control unit will inf late
the driver’s and f ront passenger’s
airbags, at the time and with the
f orce needed. If you ever have a moderate to
severe f rontal collision, sensors will
detect the vehicle’s rapid
deceleration. 34

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 or small-statured adults 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 objects or metal items
under the f ront seats.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. Failure to f ollow these instructions
could damage the sensors or prevent
them f rom working properly.
Objects placed or pushed under
the f ront passenger’s seat may
cause the sensor to malf unction,
increasing the risk of injury in a
crash.

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 f ront airbag of f .Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned of f .
When the passenger airbag gets
turned of f by the weight sensors, a
‘‘passenger airbag of f ’’ indicator in
the center of the dashboard comes
on (see page ).
If the weight sensors detect there is
no passenger in the f ront seat, the
airbag is automatically turned off.
However, the passenger airbag of f
indicator in this situation will not
come on.To ensure that the passenger’s
advanced front airbag system will
work properly,
This includes:
Hanging heavy items on the f ront
passenger seat, or placing heavy
items in the seat-back pocket. Moving the f ront seat f orcibly
back against cargo on the seat or
f loor behind it. A rear passenger pushing or
pulling on the back of the f ront
passenger’s seat.
Back seat passengers should not
wedge objects or intentionally
f orce their f eet under the f ront
passenger seat. 35

If you ever have a moderate to
severe side impact, sensors will
detect rapid acceleration 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. 477

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.
Thesideairbagmayalsoshutoff if a
short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag’s
deployment path.
Objects placed on the f ront
passenger seat can also cause the
side airbag to be shut of f .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

A f ront seat passenger should not
use a cushion or another object as a
backrest. It may prevent the cutof f
system f rom working properly.In a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag. 35

This indicator alerts you that the
passenger’s side airbag has been
automatically shut off. It does
mean there is a problem with your
side airbags.
When you turn the ignition switch to
the ON (II) position, the indicator
should come on brief ly and then go
out (see page ). If it does not
come on, stays on, or comes on while
driving without a passenger in the
f ront seat, you will also see a
‘‘PASSENGER SIDE AIRBAG OFF’’
message on the multi-inf ormation
display. Have the system checked
(see page ).This indicator alerts you that the
passenger’s f ront airbag has been
shut of f because weight sensors
detect about 65 lbs (29 kg) or less
(the weight of an inf ant or small
child) on the f ront passenger’s seat.
It does there is a problem
with the airbag.If an adult or teenage passenger is
riding in f ront, move the seat as f ar
to the rear as possible, and have the
passenger sit upright and wear the
seat belt properly. Be aware that objects placed on the
