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.
When you adjust a f an control, the
f an is taken out of AUTO mode.
In AUTO mode, the vehicle’s interior
temperature is independently
regulated f or the driver and f ront
passenger according to each
adjusted temperature. The system
also regulates each temperature
basedontheinformationof the
sunlight sensor and the sun’s
position which is updated
automatically by the navigation’s
global positioning system (GPS). If
onesideof thevehicleisgettingtoo
much sun, the system lowers the
temperature only on that side.When you press this button, the
indicator in the button comes on, and
the passenger’s side temperature is
synchronized to the driver’s side set
temperature. Changing the
passenger’s side temperature makes
the indicator go off and takes the
system out of SYNC mode.
Each time you press this button, the
climate control system switches
betweenonandoff.Turningonthe
system with this button selects your
last climate control selection.
To turn the system completely of f ,
press the ON/OFF button.

Store or secure all items that could
be thrown around and hurt
someone during a crash.
Do not put any items on top of the
rear shelf . They can block your
view and be thrown around the
vehicle during a crash.
Be sure items placed on the f loor
behind the f ront seats cannot roll
under the seats and interf ere with
the driver’s ability to operate the
pedals, the operation of the seats,
or the operation of the sensors
under the seats.Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.
Keep all cargo below the bottom
of the windows. If it is higher, it
could interf ere with the proper
operation of the side curtain

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you cannot make the low tire
pressure indicator go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
Each tire has its own pressure
sensor (not including the spare tire).
If the air pressure of a tire becomes
signif icantly low while driving, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on.
Driving on a signif icantly under
inf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.

The exhaust emissions controls
includethreeorfoursystems:
PGM-FI, ignition timing control,
exhaust gas recirculation (6-cylinder
models), and three way catalytic
converter. These 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 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
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 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) 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. 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.
