If you think you can safely 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 significantly underinflated.
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
information placard.
It is possible that the
pressures shown on the multi-
information display and the
pressures you manually
measure are slightly different.
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 significantly 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- information 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.
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. After
several miles (kilometers) driving,
this indicator begins to flash,
then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
information display. This is normal;
the system cannot monitor the
spare tire pressure. Manually check
the spare tire pressure to be sure it
is correct. Each wheel (except the compact
sparetirewheel)isequippedwitha
tire pressure sensor. You must use
TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
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.

The floor mats that came
with your vehicle hook over the
floor mat anchors. This keeps
the floor mats from sliding
forward, possibly interfering
with the pedals, or backwards,
making the front passenger’s
weight sensors ineffective.
If you remove a floor mat, make sure
to re-anchor it when you put it back
in your vehicle.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.
This filter removes the dust and
pollen that is brought
in from the outside through the
heating and cooling system/
climate control system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the
information display or multi-
information display (depending on
the models). It should be replaced
every 15,000 miles (24,000 km) if
you drive primarily in urban areas
that have high concentrations of
soot in the air, or if the flow
from the heating and cooling
system/climate control system
becomes less than usual.

The following chart shows the
recommended cold tire pressures
for 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.
Thecompactsparetirepressureis:
Excessive tread wear. Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord. Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.

tire sizes and cold tire pressures are

The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way
catalytic converter. These four
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 from the
crankcase and evaporative
emissions control systems.
The PGM-FI system uses
sequential multiport fuel injection.
It has three subsystems: air intake,
engine control, and fuel control.
The powertrain control module
(PCM) uses various sensors to
determine how much air is going
into the engine. It then controls
how much fuel 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 manifold. Adding
exhaust gas to the air/fuel mixture
reduces the amount of NOx
produced when the fuel 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
from the rest of your vehicle.
Read your warranty manual for
more information. 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.
