Maintenance Safety

Important Safety Precautions
Before you begin any maintenance,
make sure your vehicle is parked on
level ground and that the parking
brake is set. Also, be sure the engine is off. This will help to eliminateseveral potential hazards: Carbon monoxide poisoning
from engine exhaust. Be sure
there is adequate ventilation
whenever you operate the engine.
Burns from hot parts. Let the
engine and exhaust system cool
before touching any parts.
Injury from moving parts. Do
not run the engine unless in-
structed to do so. Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of fire or explosion, be careful when working
around gasoline or batteries. Use a
nonflammable solvent, not gasoline,
to clean parts. Keep cigarettes, sparks, and flames away from the
battery and all fuel-related parts.
You should wear eye protection and protective clothing when workingnear the battery or when using
compressed air.

Battery
Check the condition of your vehicle's
battery monthly. You should check
the color of the test indicator window,
and for corrosion on the terminals.
Check the battery condition by
looking at the test indicator window on the battery.
The label on the battery explains the test indicator's colors.

Battery
Check the battery terminals for
corrosion (a white or yellowish
powder). To remove it, cover the terminals with a solution of bakingsoda and water. It will bubble up and
turn brown. When this stops, wash it
off with plain water. Dry off the
battery with a cloth or paper towel. Coat the terminals with grease to
help prevent future corrosion. If the terminals are severely cor-
roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables from
the terminals. Always disconnect the negative ( —) cable first and recon-
nect it last. Clean the battery termi-
nals with a terminal cleaning tool or
wire brush. Reconnect and tighten the cables, then coat the terminals
with grease.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damage to the vehicle's electrical system.

Maintenance

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled mechanic do the battery

If your vehicle's battery is discon-
nected or goes dead, the audio system will disable itself. The next
time you turn on the radio you will see "Code" in the frequency display.Use the Preset buttons to enter the
five-digit code (see page 117).

Charging the battery with the cables
connected can seriously damage your vehicle's electronic controls. Detach
the battery cables before connecting
the battery to a charger.

Storing Your Vehicle

If you need to park your vehicle 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 vehicle back on the road. If
possible, store your vehicle indoors. Fill the fuel tank.
Change the engine oil and filter
(see page 175). 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 Reverse (5- speed manual) or Park (automatic). Block the rear wheels. If the vehicle 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 vehicle 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 vehicle with a
"breathable" vehicle 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 vehicle for 12
months or longer, have your Honda 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 164).
The replacements called for in the maintenance schedule are not
needed unless the vehicle hasactually reached that time or mileage.

If Your Engine Won't Start

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 vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page 69).
A key that is not properly coded will cause the immobilizer systemindicator in the dash panel to blinkrapidly. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed all the way to the floor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral. Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlightsare very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 236.
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 ignitionswitch or starter motor. You will
need a qualified technician to
determine the problem. (See
Towing on page 250.) 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 190). You can
then try jump starting the vehicle
from a booster battery (see page
236).

If Your Engine Won't Start, Jump Starting

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 133.
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 245).

If you find nothing wrong, you will

need a qualified technician to find

the problem. See Towing on page
250. Jump Starting
If your vehicle's battery has rundown, 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 a Honda with an automatic transmission by pushing
or pulling it. To jump start your vehicle, follow
these directions closely:
1. Open the hood and check the physical condition of the battery(see page 190). 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.

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: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.

A battery can explode if you do

not follow the correct procedure,
seriously injuring anyone nearby.

Jump Starting

3. Connect one jumper cable to the positive ( + ) terminal on the
booster battery. Connect the other
end to the positive ( + ) terminal
on your Honda's battery. 4. Connect the second jumper cable
to the negative (—) terminal on
the booster battery. Connect theother end to the grounding strap
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.
BOOSTER BATTERY

6. Start your vehicle. If the starter motor still operates slowly, check
the jumper cable connections to make sure they have good metal-
to-metal contact.
7. Once your vehicle is running, disconnect the negative cable from
yourvehicle, then from the booster battery. Disconnect the
positive cable from your vehicle,
then the booster battery.
