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

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. 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 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. How Your Front Airbags Work

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. 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 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.
Although Honda 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.
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 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.

To regulate the interior temperature,
the system has two sensors. A
sunlight sensor is located in the top
of the dashboard and a temperature
sensor is next to the steering column.

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.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 to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more inf orma-
tion.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
transmission control module (TCM)
in automatic transmission (CVT)
vehicles or the engine control
module (ECM) in manual
transmission vehicles uses various
sensors to determine how much air is going into the engine. It then
controls how much f uel to inject
under all operating conditions.
