Make sure all items in the trunk, or
items extending through the opening
into the back seat, are secured.
Looseitemscanflyforwardand
cause injury if you have to brake
hard. See on page.
Never drive with the seat-back
f olded down and the trunk lid open.
See on
page .
Make sure that the folded seat-back
does not press against the f ront
passenger’s seat, as this could cause
the weight sensors to work
improperly.
Make sure all rear shoulder belts are
positioned in f ront of the rear seat-
back, and the center shoulder belt is
re-positioned in the guide whenever
the seat-back is in its upright position.
Be sure there are no twists in any
shoulder belt.
Do not put any heavy items on the
seat-back when it is folded down.

Store or secure all items that could
be thrown around and hurt
someone during a crash.Distribute cargo evenly on the
f loor of the trunk, placing the
heaviest items on the bottom and
as far forward as possible.
If you carry large items that
prevent you f rom closing the trunk
lid, exhaust gas can enter the
passenger area. To avoid the
possibility of

on page .
If youfolddownthebackseat,tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
Do not put any items on top of the
trunk panel. 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
underneath and interf ere with the
proper operation of the seats, the
sensors under the seats, or the
driver’s ability to operate the
pedals.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop. 51

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.Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf 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.
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.
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.

As required by the FCC:This device complies with Part 15 of theFCC rules. Operation is subject to the
f ollowing two conditions: (1) This devicemay not cause harmf ul interf erence, and(2) this device must accept any
interf erence received, includinginterf erence that may cause undesiredoperation.
Changes or modif ications not expresslyapproved by the party responsible f or
compliance could void the user’sauthority to operate the equipment.
This device complies with IndustryCanada Standard RSS-210.Operation is subject to the f ollowing two
conditions: (1) this device may not causeinterf erence, and (2) this device mustaccept any interf erence that may cause
undesired operation of the device.
If you have a f lat tire, the low tire
pressure indicator will come on.
Replace the flat tire with the
compact spare tire (see page ).
Each wheel (except the compact
sparetirewheel)isequippedwitha
tire pressure sensor mounted inside
the tire behind the valve stem. You
must use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualif ied technician.
After you replace the flat tire with
thecompactsparetire,thelowtire
pressure indicator stays on. This is
normal; the system is not monitoring
the spare tire pressure. Manually
check the spare tire pressure to be
sure it is correct. Af ter several miles
(kilometers) driving with the
compact spare tire, the TPMS
indicator comes on and the low tire
pressure indicator goes of f . The low tire pressure indicator or
the TPMS indicator will go off, after
several miles (kilometers) driving,
when you replace the spare tire with
the specif ied regular tire equipped
with the tire pressure monitor sensor.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Check these things:Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or neutral.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See on page .
Store the jack and tools in the tool
case. Place the tool case in the
center of the f lat tire.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.
Lower the trunk f loor, and close

You hear nothing, or almost
nothing. The engine’s starter

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 f rom
the rest of your vehicle. Read your
warranty manual f or more inf orma-
tion.
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 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.
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.
