2003 HONDA ACCORD Light

If the indicator remains on past three
driving trips, or the f uel cap was not
loose or missing, have the car
checked by the dealer as soon as
possible. Drive moderately until the
dealer has inspected the problem.
Avoid full-throttle acceleration and
driving at high speed.
Youshouldalsohavethedealer
inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.
This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. If it comes on
at any other time, it indicates one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your car’s perf ormance, it can
reduce your f uel economy and cause
your car to put out excessive
emissions. Continued operation may
cause serious damage. If you have recently ref ueled your
car, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks several
times. Replace the f uel f ill cap if it is
missing. Tightening the cap will not
make the indicator turn of f
immediately; it takes at least three
driving trips.

MALFUNCTION INDICATOR LAMP
If you keep driving with the
malf unction indicator lamp on, you can
damage your car’s emissions controls
and engine. Those repairs may not be
covered by your car’s warranties.

ÎIf it comes on at any other time, it
indicates a problem with the car’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
fluid level is low, take the car to your
dealer and have the brake system
inspected f or leaks or worn brake
pads.
However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the car
begins to slow down, and you will
have to press harder on the pedal.
The distance needed to stop will be
much longer. Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the car. You
should have it towed, and repaired as
soon as possible. (See
on page .)
The Brake System Indicator
normallycomesonwhenyouturn
the ignition switch ON (II). It is a
reminder to check the parking brake.
It comes on and stays lit if you do not
f ully release the parking brake. If you must drive the car a short
distance in this condition, drive
slowly and cautiously.
If the ABS indicator comes on with
this indicator, have the car inspected
by your Honda dealer immediately.

Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
Remove the cover f rom the f use
box.
If something electrical in your car
stops working, the f irst thing you
should check f or is a blown f use.
Determine f rom the chart on pages
and , or the diagram on the
fuse box lid, which fuse or fuses
control that component. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
not the cause. Replace any blown
f uses and check the component’s
operation. Check each of the large f uses in
the under-hood f use box by
looking at the wire inside.
Removing these f uses requires a
Phillips-head screwdriver.

ÎThe burning of gasoline in your car’s
engine produces several byproducts.
Some of these are carbon monoxide
(CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline
evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC
is important to the environment.
Under certain conditions of sunlight
and climate, NOx and HC react to
f orm photochemical ‘‘smog.’’ Carbon
monoxide does not contribute to
smog creation, but it is a poisonous
gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
.
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your car has a Positive Crankcase
Ventilation System. This keeps
gasses that build up in the engine’s
crankcase from going into the
atmosphere. The Positive Crankcase Ventilation valve routes them from
the crankcase back to the intake
manif old. They are then drawn into
the engine and burned.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.

Then drive in city/suburban
traffic for at least 10 minutes.
When traf f ic conditions allow, let
the car coast for several seconds
without using the accelerator
pedal or the brake pedal.
If the testing f acility determines the
readiness codes are still not set, see
your Honda dealer.
Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
(80to97km/h)foratleast20
minutes. Drive on the highway in
D (A/T) or 5th (M/T). Do not use
thecruisecontrol.Whentraffic
allows, drive f or 90 seconds
without moving the accelerator
pedal. (Car speed may vary
slightly; this is okay.) If you cannot
do this f or a continuous 90
seconds because of traf f ic
conditions, drive f or at least 30
seconds, then repeat it two more
times (for a total of 90 seconds).
