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 inflate them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.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, 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.
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 ).218

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.

Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.
If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry bef ore
you use the vehicle. If your vehicle is equipped with
genuine Honda f loor mats, the mats
hook over f loor mat anchors. This
keeps the f loor mats f rom sliding
f orward and possibly interf ering with
the pedals or making the front
passenger’s weight sensors
inef f ective.

A non-Honda f loor mat may not f it
your vehicle properly. This could
prevent the proper operation of the
f olding rear seats and the passenger’s
seat weight sensors. We recommend
using genuine Honda f loor mats. Do
not put additional f loor mats on top
of the anchored mats.
If you remove a f loor mat, make sure

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 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.
