Fill the f uel tank.
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.
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 12 volt battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
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.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, suchas plastic sheeting, trap moisture,
which can damage the paint.
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.
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.
Vehicle Storage

If this vehicle is unused f or over one
month, the service lif e of the 158V
Nickel-Metal Hydride battery will be
reduced and the battery may be
permanently damaged.

Diagnosing why the engine won’t
start f alls 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 12 volt battery is
discharged or the connections are
corroded. Check the condition of
the 12 volt battery and terminal
connections (see page ). You
canthentryjumpstartingthe
vehicle f rom a booster 12 volt
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
f aster than normal, but the engine
does not start up and run.
When 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 f uses. If the f uses
areOK,thereisprobably
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 .
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 .319 333

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 instant f uel economy 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.

Start the engine, and set the
interior temperature 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 check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon 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 f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
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 (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

If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).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 come
on.
Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning lights.
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.
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
).
This indicator 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. 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 the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by your 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 emissions 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 due to a loose or missing
f uel f ill cap. You will also see a
‘‘CHECK FUEL CAP’’ message on
the inf ormation display. Tighten the
cap until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition switch to the ON (II)
position, 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 f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.
