Make sure the engine and radiator
are cool.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pour the coolant slowly and
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap back on, and
tighten it fully.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down. Remove the radiator cap cover. Remove the radiator cap by

Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
If the washer f luid is low, a
‘‘WASHER FLUID LOW’’ message
appears on the multi-inf ormation
display.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

Always use Honda ATF-Z1
(automatic transmission f luid). If it’s
not available, you may use a
DEXRON

transmission f luid as a temporary
replacement. However, continued
use can affect the shift quality. Have
the transmission f lushed and ref illed
with Honda ATF-Z1 as soon as it is
convenient.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
If the level is below the lower
mark, add f luid into the dipstick
hole to bring it to the level
between the upper and lower
marks.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Make sure the rubber cap on the
dipstick f its in the dipstick guide
and that you push the dipstick in

(100,000 km) if you regularly drive
your vehicle in one or more of these
conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
Check the level on the side of the
reservoir when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering f luid to the
UPPER LEVEL mark. Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
The timing belt should be replaced
at the intervals shown in the
maintenance minder schedule.
If you f requently tow a trailer.
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.
If you are not sure how to add
f luid, contact your dealer.

If you need to park your vehicle f or
an extended period (more than 1
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.Fill the f uel tank.
Change the engine oil and f ilter.
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. 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).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
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. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.

Diagnosing why the engine won’t
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position: 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.
Wh en you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. Check
the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page . If
the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
from a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.
Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the dash panel to blink
rapidly(seepage ).
Check these things: Turn
the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
on page . 426
