Battery

If your car's battery is disconnected
or goes dead, the engine's computer
needs to "relearn" the idle control.
After replacing or recharging the
battery:

1. Make sure the climate control sys-
tem is off.

2. Start the engine and let it run until

it warms up (the radiator cooling
fan comes on at least twice), and
let it idle for five more minutes.

Your audio system will also disable it-
self when the battery is disconnected
or goes dead. The next time you turn
on the radio you will see "Code" in
the frequency display. Use the Pre- set buttons to enter the five-digit
code (see page 164 ).

Charging the battery with the cables
connected can seriously damage your
car's electronic controls. Detach the
battery cables before connecting the

battery to a charger.

NOTICE

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.

HOLDING CLIP

Storing Your Car

If you need to park your car for an extended period (more than one
month), there are several things you should do to prepare it for storage.
Proper preparation helps prevent deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors. Fill the fuel tank.
Change the engine oil and filter
(see page 219).
Wash and dry the exterior
completely.
Clean the interior. Make sure the
carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the car is to be stored for a
longer period, it should be supported on jackstands so the
tires are off the ground.
Leave one window open slightly (if
the car is being stored indoors).
Disconnect the battery.
Support the front wiper blade
arms with a folded towel or rag so
they do not touch the windshield. To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a vehicle body wax to the painted
surfaces that mate with the door
and trunk seals. Cover the car with a "breathable"
cover, one made from a porous
material such as cotton. Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint. If possible, run the engine for a
while periodically (preferably once
a month).
If you store your car for 12 months or longer, have your Acura dealer
perform the inspections called for in
the 24 months/30,000 miles (48,000
km) maintenance schedule (Normal Conditions) as soon as you take it
out of storage (see page 208). The
replacements called for in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage.

Taking Care of the Unexpected

This section covers the more- common problems that motorists
experience with their vehicles. It
gives you information about how to safely evaluate the problem and what
to do to correct it. If the problem has stranded you on the side of the road,
you may be able to get going again. If not, you will also find instructions
on getting your car towed. Compact Spare Tire....................... 272

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.

Jump Starting

If a battery sits in extreme cold, the electrolyte inside can freeze.
Attempting to jump start with a frozen battery can cause it to rupture.

2. Turn off all the electrical acces- sories: climate control, stereo
system, lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.
3. Connect one jumper cable to thepositive ( + ) terminal on your
Acura's battery. Connect the other end to the positive (
+ ) terminal
on the booster battery. 4. Connect the second jumper cable
to the negative ( — ) terminal on
the booster battery. Connect theother end to the ground wire on
the right side of the engine as shown. Do not connect this jumper
cable to any other part of the

engine.

5. If the booster battery is in another vehicle, have an assistant startthat vehicle and run it at a fast idle.
