You’ll
find many safety
recommendations throughout this
section, and throughout this manual.
Therecommendationsonthispage
are the ones we consider to be the
most important.
A seat belt is your best protection in
all typ es of collisions. Airbags are
designed to supplement seat belts,
not replace them. So even though
your vehicle is equipped with airbags,
make sure you and your passengers
always wear your seat belts, and
wear them properly (see page ).
Alcohol and driving don’t mix. Even
one drink can reduce your ability to
respond to changing conditions, and
your reaction time gets worse with every
additional drink. So don’t drink
and drive, and don’t let your friends
drink and drive, either.
Excessive speed is a maj or factor in
crash injuries and deaths. Generally,
the higher the speed, the greater the
risk, but serious injuries can also
occur at lower speeds. Never drive
faster than is safe for current
conditions, regardless of the
maximum speed posted.
While airbags can save lives, they
can cause serious or fatal injuries to
occupants who sit too close to them,
or are not properly restrained.
Infants, young children, and short
adults are at the greatest risk. Be
su re to follow all instru ctions and
warnings in this manual.
Children
age 12 and under should
ride properly restrained in a back
seat, not the front seat. Infants and
smallchildrenshouldberestrained
in a child seat. Larger children
should use a booster seat and a lap/
shoulder belt until they can use the
belt properly without a booster seat
(see pages ).
Having a tire blowout or a
mechanical failure can be extremely
hazardous. To reduce the possibility
of such problems, check your tire
pressures and condition frequently,
and perform all regularly scheduled
maintenance (see page ).

Only on models equipped withNavigation System
The climate control system f or your
vehicle can also be operated using
the voice control system. See the
NavigationsectioninyourQuick
Start Guide f or an overview of this
system and the Navigation System
manual f or complete details.
The automatic climate control
system adjusts the f an speed and
airflow levels to maintain the interior
temperature you select. You can manually select various
f unctions of the climate control
system when it is in f ull automatic
mode. All other f eatures remain
automatically controlled.
Making any manual selection causes

Turn this dial to increase or decrease
the fan speed and airflow.
Turning this dial clockwise increases
the temperature of the airflow.
Set the desired temperature by
turning the temperature control
dial. You will see AUTO in the
system’s display. Press the AUTO button. The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your pref erence.
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
In cold weather, the fan will not
come on automatically until the
heater starts to develop warm air.
In ‘‘AUTO’’ mode, the air conditioner
may not work if the humidity inside
the vehicle is low. To activate the air
conditioner, press A/C button.

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
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.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 informa-
tion.
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)
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 ), nitrogen
(N ), and water vapor.
