Air Conditioning System

Your car's air conditioning is a sealed system. Any major maintenance,such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure the
air conditioning works efficiently.
Periodically check the engine's
radiator and air conditioning
condenser for leaves, insects, anddirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.

The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.
Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at asteady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant. If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Refrigerant HFC-134a (R-134a). (See Specifications on page 302.)
Whenever you have the air conditioning
system serviced, make sure the service
facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasingrefrigerant into the atmosphere can
damage the environment.

Changing a Flat Tire, If Your Engine Won't Start

19.Slip the hole at the top of the jack over the bracket in the trunk well.
Turn the jack's end bracket to lock it in place. Store the tool kit back
in its place.
20.Unclip the hook from the trunk lid and lower the trunk floor.
21.Store the center cap and spacer basket in the trunk. Make sure the
center cap will not get scratched
or damaged.
22.Close the trunk lid. If Your Engine Won't Start
Diagnosing why your engine won't
start falls into two areas, depending
on what you hear when you turn the
key to START (III): You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or operates very slowly.
You can hear the starter motor operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine does not start up and run. Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to START (III), you do not hear the
normal noise of the engine trying tostart. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Your car has the ImmobilizerSystem. You should use a
properly-coded master or valet key
to start the engine (see page 78).
A key that is not properly coded will cause the immobilizer system indicator in the dash panel to blink
rapidly.
Check the transmission interlock.
The transmission must be in Park or Neutral or the starter will not
operate.

Taking Care of the Unexpected

Loose items can fly around the

interior in a crash and could

seriously injure the occupants.

Store the wheel, jack and tools

securely before driving.

If Your Engine Won't Start

Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 280 .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. (See

Emergency Towing on page 296 .)
If the headlights dim noticeably or
go out when you try to start the engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page 236). You can
then try jump starting the car from a booster battery (see page 280).
The Starter Operates Normally In this case, the starter motor'sspeed sounds normal, or even faster
than normal, when you turn the ignition switch to START (III), but
the engine does not run. Are you using the proper starting
procedure? Refer to Starting the
Engine on page 181. Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light may not be working, so you were
not reminded to fill the tank. There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page 292).

If you find nothing wrong, you will
need a qualified technician to find
the problem. See Emergency
Towing on page 296 .

Taking Care of the Unexpected

Jump Starting
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 your Acura bypushing or pulling it. To jump start your car, follow these
directions closely:
1. Open the hood and check the physical condition of the battery(see page 236). 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.

Taking Care of the Unexpected
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 Your Engine Overheats
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 296 ).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page172 ). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have toadd coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator capcounterclockwise, without pushing
down, to the first 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. 10.Start the engine and set the
temperature control dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained andrefilled with the proper mixture assoon as you can.
11. 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 Emergency
Towing on page 296 .)
12.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.

Taking Care of the Unexpected
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.

Low Oil Pressure Indicator

This indicator should light when the ignition switch is ON (II), and go outafter the engine starts. It should
never come on when the engine is
running. If it starts flashing, it
indicates that the oil pressure dropped very low for a moment, then
recovered. If the indicator stays on
with the engine running, it shows that the engine has lost oil pressureand serious engine damage is
possible. In either case, you should
take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safely get
the car stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open the hood and check the oil level
(see page 171). Although oil leveland oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 217 ). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a mechanical problem that needs to
be repaired before you can continue driving. (See Emergency
Towing on page 296 .)

LOW OIL PRESSURE INDICATOR

NOTICE

Malfunction Indicator Lamp

This indicator comes on for a few
seconds when you turn the ignition
switch ON (II). 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 feel no difference in your
car's performance, it can reduce

your fuel economy and cause your car to put out excessive emissions.
Continued operation may cause

serious damage.
If you have recently refueled your
car, the cause of this indicator
coming on could be a loose or
missing fuel fill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is missing. Tightening the cap will not
make the indicator turn off
immediately; it takes at least three driving trips.
If the indicator remains on past three
driving trips, or the fuel 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.
You should also have the dealer inspect your car if this indicator
comes on repeatedly, even though it
may turn off as you continue driving.
If you keep driving with the

malfunction indicator lamp on, you can

damage your car's emissions controls

and engine. Those repairs may not be
covered by your car's warranties.
