mild cleaner, then lubricate it with a
multipurpose grease. Lubricate all
the moving parts (as shown),
including the pivot. Follow the time
and distance recommendations in
the Maintenance Schedule. If you
are not sure how to clean and grease
the latch, contact your Honda dealer. Loosen the f our bolts with a

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 vehicle’s air conditioning is a
sealed system. Any major mainte-
nance, 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. 386

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.

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.
If you are changing the bulb on
the driver’s side, start the engine,
turn the steering wheel all the way
to the right, and turn off the
engine. If you are changing the
bulb on the passenger’s side, turn
the steering wheel to the left.
Insert the new bulb into the hole,
making sure the tabs are in their
slots. Pivot the hold-down wire
back in place and clip the end into
the slot.
Install the rubber seal over the
back of the headlight assembly.
Make sure it is right side up; it is
marked ‘‘TOP.’’
Push the electrical connector onto
the new bulb. Make sure it is
connected securely.
Reinstall the air intake cover. (Driver’s side) Turn on the headlights to test the
new bulb.

If you need to park your vehicle 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 vehicle back on the road. If
possible, store your vehicle indoors.Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Fill the f uel tank.
Change the engine oil and f ilter
(see page ).
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield. Disconnect the battery.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘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).
If you store your vehicle f or 12
months or longer, have your Honda
dealer perf orm the inspections called
f or 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 ).
The replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage.

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. Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
the f uses are OK, there is proba-
bly something wrong with the
electrical circuit f or the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (See
on page .)
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.
The transmission must be in Park
orNeutralorthestarterwillnot
operate.
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 . 380
