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.’’
An indicator on the instrument
panel that alerts you that the
passenger’s side airbag has been
turned of f (see page ).
Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash. 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 is in ON (II).
An indicator on the instrument
panel that alerts you to a possible
problem with your airbags,
sensors, or seat belt tensioners
(see page ).
Automatic seat belt tensioners
(see page ).
Sensors that can detect a
moderate to severe front impact,
or side impact in models with side
airbags.
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 ).
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 ).
Sensors that can detect whether
a child is in the passenger’s side
airbag path and automatically
turn the airbag off (see page
). 27

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.
During a f rontal crash, your seat belt
restrains your lower body and torso,
and the 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.

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.
To reduce the risk of injury f rom an
inf lating side airbag, your vehicle has
an automatic cutoff system for the
passenger’s side airbag.
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
on or goes of f .
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.
Although Acura does not encourage
children to ride in f ront, this system
is designed to shut of f the side
airbag if a child leans into the side
airbag’s path.
If you ever have a moderate to
severe side impact, 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. 28

In a moderate to severe side impact,
sensors will detect rapid deceleration
and signal the control unit to
instantly inflate the side curtain
airbag on the driver’s or the
passenger’s side of the vehicle.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
upright and well back in their seats.
The SRS indicator alerts
you to a potential problem
with your airbags or seat belt
tensioners.
When you turn the ignition switch to
ON (II), this indicator will come on
brief ly then go out. This tells you the
system is working properly.
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:
If the SRS indicator does not come
on after you turn the ignition
switch to ON (II).
If the indicator stays on after the
engine starts.
If the indicator comes on or

The odometer shows the total
distance your vehicle has been
driven. It measures miles in U.S.
models and kilometers in Canadian
models. It is illegal under U.S.
federal law and Canadian provincial
regulations to disconnect, reset, or
alter the odometer with the intent to
change the number of miles or
kilometers indicated. The temperature sensor is in the
f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road
surf ace, engine heat, and the
exhaust f rom surrounding traf f ic.
This can cause an incorrect
temperature reading when your
speed is under 19 mph (30 km/h).
The sensor delays the display update
until it reaches the correct outside
temperature. This may take several
minutes.
If the outside temperature is
incorrectly displayed, you can adjust
it up to 5°F ( 3°C) warmer or
cooler.
NOTE: The temperature must be
stabilized bef ore doing this
procedure.
This display shows the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models). To see the outside
temperature, press and release the
Select/Reset knob until the
temperature is displayed.

After the seat reaches a comfortable
temperature, select LO by pushing
the back of the switch. This will keep
the seat warm.
In HI, the heater turns of f when the
seat gets warm, and turns back on
after the seat’s temperature drops.
In LO, the heater runs continuously.
It does not cycle with temperature
changes.Follow these precautions whenever
you use the seat heaters:
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current f rom the
battery.
If the engine is lef t idling f or an
extended period, do not use the
seat heaters even on the LO
setting. It can weaken the battery,
causing hard starting.
Both f ront seats are equipped with
seat heaters. Because of the sensors
f or the side airbag system, there is
no heater in the passenger’s seat-
back. The ignition switch must be
ON (II) to use the heaters.

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection. It has three
subsystems: air intake, engine
control, and f uel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. Itthen controls how much f uel to inject
under all operating conditions.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor. The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
