If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
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 ).
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/TPMS
indicator may come on unexpectedly.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display 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. 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/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.
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 the low tire pressure/TPMS
indicator comes on, or the multi-
inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message,
the VSA system automatically turns
on even when the VSA system is
turned of f by pressing the VSA OFF
switch (see page ). If this
happens, you cannot turn the VSA
system of f by pressing the VSA OFF
switch again.
When you restart the vehicle with
thecompactsparetire,theTPMS
system message will also be
displayed on the multi-inf ormation
display af ter several miles
(kilometers) driving.This indicator and the warning
message on the multi-information
display will go of f , af ter several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a 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
a qualif ied technician.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

If you have a f lat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated f lat tire with the compact
sparetire(seepage ).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct.

the models). It should be replaced
every 15,000 miles (24,000 km) if you
drive primarily in urban areas that

The following chart shows the
recommended cold tire pressures f or
most normal and high-speed driving
conditions.Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread lef t on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.

Cuts, splits, or cracks in the side
of the tire. Replace the tire if you

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)
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.
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 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.
