2003 Acura RSX check engine

´´
To jump start your car, f ollow these
directions closely:
Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake. Connect one jumper cable to the
positive ( ) terminal on your
Acura’s battery. Connect the other
end to the positive ( ) terminal
on the booster battery.
If your car’s battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
You cannot start an Acura with an
automatic transmission by pushing
or pulling it. 1.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

µ
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.Once your car is running, discon-
nectthenegativecablefromyour
car, then from the booster battery.
Disconnect the positive cable f rom
your car, then the booster battery. Start your car. If the starter motor
still operates slowly, check the
jumper cable connections to make
sure they have good metal-to-
metal contact.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until all are
disconnected. Otherwise, you may
cause an electrical short.
The numbers in the illustration show
you the order to connect the jumper
cables.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.

BOOSTER BATTERY

Start the engine and set the
temperature control lever to
maximum. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly. Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See
on page .)
If there was no coolant in the
reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator. Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

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.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 .)
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.

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.

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
days of normal driving.
If the indicator remains on past that,
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 f ull-
throttle acceleration and driving at
high speed.

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.

Your car 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 car’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.If possible, do not take your car 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. See State
Emissions Testing on pages and
