Even if the passenger’s f ront airbag
is turned of f , we strongly
recommend that children age 12 and
under ride properly restrained in a
back seat where they will be saf er.
Front airbags have been designed to
help protect adults in a moderate to
severe f rontal collision. To do this
the passenger’s f ront airbag is quite
large and it can inf late with enough
f orce to cause very serious injuries.
To help prevent airbag-caused
injuries to children, this vehicle has
an advanced airbag system.
With this system, the front
passenger’s airbag is turned of f if
sensors detect a total weight of less
thanabout65lbs(30kg)intheseat.
(See page f or additional
inf ormation about how the f ront
passenger’s advanced airbag works.)
According to accident statistics,
children of all ages and sizes are
saf er when they are restrained in a
back seat. The National Highway
Traffic Safety Administration and
Transport Canada recommend that
all children age 12 and under be
properly restrained in a back seat.
Children who ride in back are less
likely to be injured by striking
interior vehicle parts during a
collision or hard braking. Also,
children cannot be injured by an
inf lating airbag when they ride in the
back.

This indicator comes on when you
turn the ignition switch to ON (II). If
it comes on at any other time, it
indicates a potential problem with
your f ront airbags or automatic seat
belt tensioners. This indicator will
also alert you to a potential problem
with your side airbags, passenger’s
side airbag automatic cutoff system,
driver’s seat position sensor, or f ront
passenger’s weight sensors. For
more inf ormation, see page .This indicator comes on when you
turn the ignition switch to ON (II). If
it comes on at any other time, it
indicates that the passenger’s side
airbag has automatically shut off.
For more inf ormation, see page .
This indicator normally comes on f or
a f ew seconds when you turn the
ignition switch to ON (II), and when
the ignition switch is turned to
START (III). If it comes on at any
other time, there is a problem in the
ABS. If this happens, have your
vehicle checked by your Honda
dealer. With this indicator on, your
vehicle still has normal braking
ability but no anti-lock. For more
inf ormation, see page .

Both f ront seats are equipped with
seat heaters. The ignition switch
must be in the ON (II) position to
use them. The seat heater switch is
located on each f ront door. Push the
f ront of the switch, HI, to rapidly
heat up the seat.
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 does not cycle with
temperature change.
Follow these precautions when using
the seat heaters:
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current f rom the
battery.
Because of the sensors f or the side
airbag system, there is no heater in
the passenger’s seat-back. 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.

The heating and air conditioning
systems in your Honda provide a
comf ortable driving environment in
all weather conditions.
The standard audio system has
many f eatures. This section de-
scribes those f eatures and how to
use them. (If you selected an
optional audio system, ref er to the
operating instructions that came
with it.)
The security system helps to dis-
courage vandalism and thef t of your

The exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three Way
Catalytic Converter. These four
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 Fuel Control.
The Powertrain Control Module
(PCM) 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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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 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 ), dinitrogen
(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
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
