Check the condition of the 12 volt
battery monthly by looking at the
test indicator window. The label on
the battery explains the test
indicator’s colors.
Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a cloth or paper towel. Coat the
terminals with grease to help prevent
f urther corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last. 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 ON (II). 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.

TEST INDICATOR WINDOW
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.

Fill the f uel tank.
Change the engine oil and f ilter.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.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
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. 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.
Leave the parking brake off. Put
the transmission in Reverse
(manual) or Park (CVT). 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.
If you store your vehicle f or 1 year or
longer, have your dealer perf orm the
inspections called f or in the 2 years/
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. 145

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
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral. Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
probably 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 ).
Check these things:
Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):
Turn the ignition switch to ON (II).
Turn on the headlights, and check
their brightness. If the headlights
areverydimordonotcomeonat
all, the battery is discharged. Seeon 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 12 volt battery and terminal
connections (see page ). You

Although this seems like a simple
procedure, you should take several
precautions. Open the hood, and check the
physical condition of the 12 volt
battery. In very cold weather,
check the condition of the
electrolyte. If it seems slushy or
like ice, do not try jump starting
until it thaws.
You cannot start your vehicle with an
automatic transmission (CVT) by
pushing or pulling it. To jump start your vehicle:
The numbers in the illustration show
you the order to connect the jumper
cables.Connect one jumper cable to the
positive ( ) terminal on your
battery. Connect the other end to
the positive ( ) terminal on the
booster battery.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc. Put the transmission in
Neutral or Park, and set the
parking brake.

BOOSTER BATTERY
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

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.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the metal projection
as shown. Do not connect this
jumper cable to any other part of
the engine.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle. 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 ON (II). 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.
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 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.
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.
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. Tighten the cap until it
clicks at least three times.
Tightening the cap will not turn the
indicator of f immediately; it takes at
least three days of normal driving. To check if they are set, turn the
ignition switch to ON (II), without
starting the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds.If itthengoesoff,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 inf ormation (see page ).
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. This indicator may also come on
along with the ‘‘D’’ indicator. 210
