To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1, then drive the
vehicle a short distance. Do this
three times. Then drain and ref ill the
transmission a f inal time.
If the level is below the lower
mark, remove the f ill plug and add
f luid to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill. Clean up any
spills immediately. Spilled f luid
could damage components in the
engine compartment.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If you are not sure how to add f luid,
contact your Honda dealer.
Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it is not available, you may use a
DEXRON

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the
system. Have the brake system
f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Check the f luid level in the brake
f luid reservoir monthly.
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule.
Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled f luid could
damage components in the engine
compartment.

Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently and have
the system inspected as soon as
possible.
Check the level when the engine is
cold. Look at the side of the
reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.
Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled f luid could
damage components in the engine
compartment.

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

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

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.
