2004 Acura RL engine

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open the
hood.
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. 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 ).
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.
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.
Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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 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 .)

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.

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. (Seeon page .)
Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
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. 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.

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 vehicle stopped.

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, 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.
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.

inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving. 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.
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 the indicator remains on past that,
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 f ull-
throttle acceleration and driving at
high speed.

There are three popular types of
prof essional towing equipment. If your car needs to be towed, call a
prof essional towing service or, if you
belong to one, an organization that
provides roadside assistance. Never
tow your car behind another vehicle
with just a rope or chain. It is very
dangerous. The operator
loads your car on the back of a truck.
The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. If your Acura cannot be transported
by f lat-bed, it should be towed by
wheel-lif t equipment with the f ront
wheels of f the ground. If , due to
damage, your car must be towed
with the f ront wheels on the ground,
do the f ollowing.
Release the parking brake.
Shif t the transmission to Neutral. With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the vehicle
of f the ground. Your car’s sus-
pension and body can be seriously
damaged.Flat -bed Equipment

Improper towing preparation will

Your car has several identif ying
numbers located in various places.
The Vehicle Identif ication Number
(VIN) is the 17-digit number your
Acura dealer uses to register your
car f or warranty purposes. It is also
necessary f or licensing and insuring
your car. The easiest place to find
the VIN is on a plate fastened to the
top of the dashboard. You can see it
by looking through the windshield
on the driver’s side. It is also on the
Certification label attached to the
driver’s doorjamb, and is stamped on
the engine compartment bulkhead.
The VIN is also provided in bar code
on the Certification label.
