Check the f luid level with the engine
at normal operating temperature.Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks within the HOT range.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.
Always use Honda CVT Fluid
(Continuously Variable
Transmission f luid).
Park the vehicle on level ground.
Start the engine and let it run until
the radiator fan comes on, then
shut of f the engine. For accurate
results, wait about 60 seconds
bef ore going to step 2, but don’t
wait longer than 90 seconds. 3.

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. Leave one window open slightly (if
the vehicle is being stored
indoors).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.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals. Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield. Disconnect the 12 volt battery. Reconnect the 12 volt battery and
drive your vehicle every month f or
about 30 minutes. This will keep
the IMA battery charged and in
good condition.
Leave the parking brake off. Put
the transmission in Park. 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.
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.

permanently damaged.

This section covers the more
common problems that motorists
experience with their vehicles. It
gives you inf ormation about how to
safely evaluate the problem and what
to do to correct it. If the problem has
stranded you on the side of the road,
you may be able to get going again.

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:
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 12 volt battery and terminal
connections (see page ). You
canthentryjumpstartingthe
vehicle from a booster battery
(see page ).
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 these things:
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate. 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 .
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 . 223 223212237

Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Are you using the proper starting
procedure? Refer to
on 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. Ifyoufindnothingwrong,youwill
need
a qualified technician to find
the problem. See
on page .
Do
you have fuel? Check the fuel
gauge; the low fuel indicator may
not be working.
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page ).

µStart the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle. Once your vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
then from the booster battery.
If your vehicle’s 12 volt battery is
disconnected or goes dead, the IMA
battery level gauge reading will not
be correct the next time you turn the
ignition switch to the ON (II)
position. It will show less than the
actual level temporarily. It will show
the correct level af ter you drive f or
at least 30 minutes.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine. 7. 6.

The reading on the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
When the current f uel mileage is
shownonthedisplay,the
temperature gauge will interrupt on
the display and blink for several
times if the coolant temperature
rises to 224°F (118°C) or more. At
the same time, the beeper sounds
once.
If your vehicle overheats, you should
take immediate action. The only
indicationmaybethetemperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge reading comes down to the
midpoint, then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.
Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f all
accessories, and turn on the
hazard warning lights.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
reading at the red mark can cause
serious damage to your engine.

Start the engine, and set the
interior temperature to maximum.
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
refilled with the proper mixture as
soon as you can.
Put the radiator cap back on
tightl y. Run the engine, and check
the temperatu re gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Using
gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.
Look
for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see
on page ).
If you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). Add coolant if the level is
below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator. 8. 9.
