Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.
A driver’s seat position sensor that
monitors the distance of the seat
f rom the airbag. If the seat is too
far forward, the airbag will inflate
with less f orce (see page ). Sensors that can detect whether a
child is in the passenger’s airbag
path and signal the control unit to
turn the airbag off (see page ).
Your airbag system includes:
Two SRS (Supplemental Restraint
System) airbags. The driver’s
airbag is stored in the center of
the steering wheel; the passenger’s
airbag is stored in the dashboard.
Both are marked ‘‘SRS AIRBAG.’’
Sensors that can detect a
moderate to severe front impact. Automatic seat belt tensioners
(see page ). An indicator on the dashboard that
alerts you that the passenger’s
airbag has been turned of f (see
page ).
Weight sensors and unit that
monitor the weight on the
passenger’s seat. These
automatically turn off the
passenger’s airbag if they detect
an inf ant or small child may be in
theseat(seepage ).
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
passenger seat belt use when the
ignition switch is in the ON (II)
position.

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.
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
inflate the driver’s and passenger’s
airbags, at the time and with the
f orce needed. Only the driver’s airbag will deploy if
there is no passenger in the
passenger’s seat, or if the advanced
airbag system has turned the
passenger’s airbag of f (see page ). During a f rontal crash, your seat belt
restrains your lower body and torso,
and the airbag helps protect your
head and chest.
Af ter inf lating, the airbags will
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.

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. The driver’s advanced 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.The passenger’s advanced airbag
system has weight sensors and unit
under the seat. If the sensors detect
an inf ant or small child may be in the
seat, the system will automatically
turn the passenger’s airbag off.
Your airbags are also advanced
airbags. The main purpose of this
feature is to help prevent airbag-
caused injuries to short drivers and
children who ride in the passenger’s
seat.
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 cargo or metal objects
under the seats.
Failure to f ollow these instructions
could damage the sensors or prevent
them f rom working properly.

If you see any of these indications,
the airbags and seat belt tensioners
may not work properly when you
need them.This indicator alerts you that the
passenger’s airbag has been shut of f
because weight sensors detect an
inf ant or small child may be in the
passenger’s seat. It does
there is a problem with the airbag.
When you turn the ignition switch to
the ON (II) position, this indicator
comes on brief ly then goes of f .If the indicator comes on with no
passenger in the seat, or with an
adult in the seat, there may be a
problem with the advanced airbag
system. Have the vehicle checked by
your dealer as soon as possible. If no one is riding in the passenger’s
seat, the airbag will be automatically
shut of f . However, the indicator will
not come on.
The passenger airbag of f indicator
may also come on and of f repeatedly
if total weight on the seat is near the
airbag cutoff threshold.
If this happens, move the seat as f ar
to the rear as possible and have the
passenger sit upright and wear the
seat belt properly.

Ignoring the SRS indicator can
result in serious injury or death
if the airbag systems or
tensioners do not work properly.
Have your vehicle checked by a
dealer as soon as possible if
the SRS indicator alerts you to
a possible problem.

Together, airbags and
seat belts provide the best
protection.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.
Even if your
airbags do not inflate, your dealer
should inspect the driver’s seat
position sensor and the passenger’s
weight sensors to make sure they
are operating properly.
Your airbag systems are virtually
maintenance f ree, and there are no
parts you can saf ely service.
However, you must have your
vehicle serviced if:
Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. If a
f ront airbag inf lates, the seat belt
tensioners must also be replaced.
Do not try to remove or replace
anyairbagbyyourself.Thismust
be done by your dealer or a
knowledgeable body shop. This could make the driver’s seat
position sensor or the passenger’s
weight sensors inef f ective. If it is
necessary to remove or modif y a

This shows how much f uel you have.
It may show slightly more or less
than the actual amount.
This shows the temperature of the
engine’s coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark. If it reaches the red
(Hot) mark, pull saf ely to the side of
the road. See page f or
instructions and precautions on
checking the engine’s cooling
system.This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models).
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 indicator
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 5°F in U.S. models ( 3°C in
Canadian models) warmer or cooler.

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
qualitypartsmayincreasethe
emissions f rom your vehicle.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
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
engine control module (ECM) 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. 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.
