2003 HONDA ACCORD COUPE light

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or a moment, then
recovered. If the indicator stays on
with the engine running, it shows
that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Letthecarsitforaminute.Open
the hood and check the oil level
(see page ). Although oil level
and oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during
cornering and other driving
maneuvers.Start the engine and watch the oil
pressure indicator. If the light
does not go out within ten seconds,
turn of f the engine. There is a
mechanical problem that needs to
be repaired bef ore you can
continue driving. (See
on page .)

LOW OIL PRESSURE INDICATOR
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f
the engine as soon as you can saf ely get
the car stopped.

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 one driving trip.
If the indicator remains on past one
driving trip, 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 may also come on
along with the ‘‘D’’ indicator.

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.

Î
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.

All the electrical circuits in your car
have fuses to protect them from a
short circuit or overload. These
f uses are located in two f use boxes.The under-hood f use box is located
near the back of the engine compart-
ment on the driver’s side. To open it,
pushthetabsasshown. Remove the cover f rom the f use
box. Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
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
f use box lid, which f use or f uses
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.
The interior f use box is on the
driver’s lower lef t side. To remove
the f use box lid, put your f inger in
the notch on the lid, and pull it
upward slightly, then pull it toward
you and take it out of its hinges. 1.
