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.The cargo net can be used to help
hold down items stored in the trunk.
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 proper operation of the
seats, or the proper operation of
the sensors under the seats. 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
, f ollow the instructions
on page .
If youfolddownthebackseat,tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
Distribute cargo evenly on the
f loor of the trunk, placing the
heaviest items on the bottom and
as f ar f orward as possible.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.
Also, 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 airbags. 50

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.
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.
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.
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.

As required by the FCC:This device complies with Part 15 of theFCC rules. Operation is subject to thef ollowing two conditions: (1) This devicemay not cause harmf ul interf erence, and(2) this device must accept anyinterf erence received, includinginterf erence that may cause undesiredoperation.
Changes or modif ications not expresslyapproved by the party responsible f orcompliance could void the user’sauthority to operate the equipment.
This device complies with IndustryCanada Standard RSS-210.Operation is subject to the f ollowing twoconditions: (1) this device may not causeinterf erence, and (2) this device mustaccept any interf erence that may causeundesired 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.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.
Lower the trunk f loor, then close
the trunk lid.
Your vehicle’s original tire has a
tire pressure monitoring system
sensor. To replace a tire, ref er to

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 howmuch 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 emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
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 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 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 exhaust emissions controls
include three or f our systems:
PGM-FI, ignition timing control,
exhaust gas recirculation (DX,
Canadian DX-G, LX, EX and EX-L),
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 comes out the tailpipe. The
exhaust emissions control systems
are separate from the crankcase and
evaporative emissions control
systems.
