Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all the accessories, and
turn on the hazard indicator.
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 comes down to the midpoint,
then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.

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.
Start the engine, and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.Put the radiator cap back on
tightly. Run the engine and watch
the temperature 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.
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.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

The engine running generates the oil
pressure. When the Auto Idle Stop is
activated, the engine is stopped, the
oil pressure is dropped, and the low
oil pressure indicator does not light.
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving.
(See on page
).
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
This light should never
come on when the engine is
running. If it starts f lashing
or stays on, the oil pressure has
dropped very low or lost pressure.
Serious engine damage is possible
and you should take immediate
action. 1.

If theAutoIdleStopisactiveforan
extended period, the charging
system indicator may come on. If it
happens, start the engine.
The charging system indicator may
also come on if the Integrated Motor
Assist (IMA) battery charge drops
below a desired level and the engine
starts to recharge the battery.
This indicator may blink af ter you
start the vehicle in the morning
when the temperature is below 20
°F ( 30°C). It will stop blinking
when the IMA battery warms up.
If the charging system
indicator comes on brightly
when the engine is running,
the 12 volt battery is not being
charged.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows and rear window
def ogger. Keep the engine running;
starting the engine will discharge the
battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

If your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to State Emissions Testing for
more information (see page ).
If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If the indicator comes on
while driving, it means one
of the engine’s emission
control systems may have a problem.
Even though you may f eel no
dif f erence in your vehicle’s
perf ormance, it can reduce your f uel
economy and cause increased
emissions. Continued operation may
cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator turn of f
immediately; it takes at least three
days of normal driving. 211

NOTICE:
If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle’s emission
controls and the engine. Those repairs
may not be covered by your vehicle’s
warranties.

The brake system indicator
normally comes on when
you turn the ignition switch
ON (II) and as a reminder
to check the parking brake.
It will stay lit if you do not
f ully release the parking
brake.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ).
If the f luid level is low, take your
vehicle to the dealer and have the
brake system inspected f or leaks or
worn brake pads.
However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down and
you will have to press harder on the
pedal.
Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed and repaired as
soon as possible (see
on page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully. If the ABS indicator comes on with
this indicator, have the vehicle
inspected by your Honda dealer
immediately.

If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse box by
pulling out each f use with the f use
puller provided in the under-hood
fuse box.
Look f or a burned wire inside the
f use. If it is burned, replace it with
oneof thesparefusesof thesame
rating or lower.
Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
Remove the cover f rom the f use
box.
Check each of the large f uses in
the under-hood f use box by
looking through the top at the wire
inside. Remove the screws with a
phillips-head screwdriver.

Replacing a f use with one
that has a higher rating greatly
increases the chances of damaging the
electrical system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.

If the radio f use is removed, the
audio system will disable itself . The
nexttimeyouturnontheradioyou
will see ‘‘COdE’’ in the f requency
display. Use the Preset buttons to
enter the f ive-digit code (see page). When the audio system is disabled,
the clock setting in the audio system
will be canceled. You will need to
reset the clock according to the
instructions in the audio system
sectiononthisowner’smanual.
If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualif ied mechanic.
