Acura MDX 2002 Owner's Manual

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 ). Let the vehicle sit f or a minute.
Open the hood and check the oil
level (see page ). Although oil
levelandoilpressurearenot
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 .)

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f

This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories:radio,heater,A/C,
climate control, rear def ogger, cruise
control, etc. Try not to use other
electrically-operated controls such as
the power windows. Keep the engine
running and take extra care not to
stall it. Starting the engine will
discharge the battery rapidly.

If the indicator remains on past three
driving trips, or the f uel cap was not
loose or missing, have the vehicle
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 vehicle if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.
This indicator comes on when you
turn the ignition switch ON (II) and
goes of f 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 vehicle’s
perf ormance, it can reduce your f uel
economy and cause your vehicle to
put out excessive emissions.
Continued operation may cause
serious damage. If you have recently ref ueled your
vehicle, 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. This indicator may also come on
along with the ‘‘D ’’ indicator.

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

If possible, do not take your vehicle
f or a state emissions test until the
readiness codes are set. To check if
they are set, turn the ignition ON (II),
but do not start the engine. The
Malf unction Indicator Lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks 5 times, the readiness
codes are not set. Ref er to State
Emissions Testing f or more
inf ormation.(See page .)
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.

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
vehicle begins to slow down, and you
will have to press harder on the
pedal. The distance needed to stop
will be much longer. If it comes on at any other time, it
indicates a problem with the vehicle’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
f luid level is low, take the vehicle to
your dealer and have the brake
system inspected f or leaks or worn
brake pads.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 vehicle. You
should have it towed, and repaired as
soon as possible. (See
on page .)
If you must drive the vehicle a short
distance in this condition, drive
slowly and cautiously.
The Brake System Indicator comes
on when you turn the ignition ON
(II). If the parking brake is not set, it
goes of f af ter you start the engine. If
the parking brake is set, it goes of f
when you f ully release the parking
brake with the engine running. 273

Determine f rom the chart on pagesand , or the diagram on the
f use box lid (the diagram f or the
driver’s side interior f use box is on
the kick panel below the f use box),
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.
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.
The secondary f use box is in the
engine compartment next to the
battery.
The primary under-hood f use box is
located in the back of the engine
compartment on the passenger’s side.
To open it, push the tabs as shown. 1.

Look f or a burned wire inside the
f use. If it is burned, replace it with
one of the spare f uses of the same
rating or lower.
Check each of the large f uses in
the primary under-hood f use box
by looking through the top at the
wire inside. Removing these f uses
requires a Phillips-head screw-
driver. Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse boxes by
pulling out each f use with the f use
puller provided in the primary
under-hood f use box.5.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualif ied mechanic.If the radio f use is removed, the
audio system will disable itself . The
nexttimeyouturnontheradioyou
will see ‘‘ ’’ in the f requency
display. Use the Preset buttons to
enter the f ive-digit code (see page
).
If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a replace-
ment f use with the proper rating f or the
circuit, install one with a lower rating.
