Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
af ter it contacts the cylinder head.)
Tightening torque:
Put the new spark plug into the
socket, then screw it into the hole.
Screw it in by hand so you do not
crossthread it.
Install the ignition coil. Reinstall
the hexagon socket head cap bolt.Push the wire connector onto the
ignition coil. Make sure it locks in
place.
Reinstall the cover on the front
cylinder bank while putting its
mounting clip in the hole on the
passenger’s side. Secure the cover
by turning the heads of the two
holding clips one-quarter turn
clockwise with a f lat-tipped
screwdriver.
Repeat this procedure f or the
other f ive spark plugs.

Tighten the spark plugs caref ully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.

Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. 364

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

all the way.
Turn on the headlights to test the
new bulb.
Reinstall the air intake cover.
Reinstall the two fasteners and
secure them by pushing on the
heads until they lock.Use a f lat-tipped screwdriver to
remove the two holding clips f rom
the inner f ender.Pull the inner f ender cover away
f rom the f ender and bumper.
(Passenger’s side) Remove the electrical connector
fromthebulbbysqueezingthe
connector to unlock the tab, then
slide the connector of f the bulb.
Remove the bulb by turning it
approximately one-quarter turn
counterclockwise.
If you are changing the bulb on
the passenger’s side, start the
engine, turn the steering wheel all
the way to the left, and turn off the
engine. If you are changing the
bulb on the driver’s side, turn the
steering wheel to the right.

Block the rear wheels.
Fill the f uel tank.
Wash and dry the exterior
completely.

carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Reverse
(5-speed manual) or Park
(automatic).
If you need to park your car f or an
extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the car is being stored indoors).
Disconnect the battery.
Support the f ront wiper blade
arms with a f olded 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 car
body wax to the painted surf aces
that mate with the door and trunk
seals.
Change the engine oil and f ilter
(see page ).
If you store your car f or 1 year or
longer, have your Honda dealer
perf orm the inspections as soon as
youtakeitoutof storage(seepages
, ). The 6-cylinder model
needs the inspections called f or in
the 2 years/30,000 miles (48,000 km)
maintenance schedule (Normal
Conditions) and the 4-cylinder model
needs the inspections called f or in
the 2 years/40,000 miles (64,000 km)
maintenance schedule (Normal
Conditions). The replacements
called f or in the maintenance
schedule are not needed unless the
car has actually reached that time or
mileage.
Coverthecarwitha‘‘breathable’’
cover, one made f rom a porous
material such as cotton. Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.
If possible, run the engine f or a
while periodically (pref erably once
amonth).

Store the jack in its holder. Turn
the jack’s end bracket to lock it in
place. Replace the cover. Store the
tools.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.Diagnosing why your engine won’t
start f alls 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
f aster than normal, but the engine
does not start up and run. When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor 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 headlights
are very dim or don’t light at all,
the battery is discharged. See on page .

Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (Seeon page .)
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 ). You can
then try jump starting the car from
a booster battery (see page ). In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Are you using the proper starting
procedure? Ref er to on page .
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly. Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .

Turn of f all the electrical acces-
sories: climate control, stereo
system, lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake.
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.
To jump start your car, f ollow these
directions closely:
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 a Honda with an
automatic transmission by pushing
or pulling it.1. 2.294

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyonenearby.
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.
