Connecting point
Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid death or serious injury, do not
lean over the battery or accidentally
let the jumper cables or clamps touch
anything except the correct battery
terminals or the ground.

Turn the engine switch to “ON” posi-
tion. Hold down the brake pedal firmly,
and place the shift lever to “N” posi-
tion. Make sure that the “N” indicator
in the instrument cluster comes on.
Then start your engine in a normal
way.
Manual transmission:Start your en-
gine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
5. Carefully disconnect the cables in the
exact reverse order: The negative
cable and then the positive cable.

224IN CASE OF AN EMERGENCY
If the cause of the battery discharging is
not apparent (for example lights left on)
you should have it checked at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If another attempt is not successful, the
battery may be depleted. Have it checked
at any authorized Toyota dealer or repair-
er, or another duly qualified and equipped
professional.If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see “If your
vehicle will not start” on page 220 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes will not work
so braking will be much harder than
usual.

260DO−IT−YOURSELF MAINTENANCE: Introduction
If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this Section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
This Section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
6, there are still a number of items that
must be done by a qualified technician
with special tools.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
CAUTION
DWhen the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
DRight after driving, the engine
compartment—the engine, radiator,
exhaust manifold, and spark plug
boots, etc. —will be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
DIf the engine is hot, do not remove
the radiator cap or coolant reser-
voir cap or loosen the drain plugs,
to prevent burning yourself.
DDo not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
DDo not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
DBe extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
DDo not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
DBe sure that the engine is off if you
work near the electric cooling fan
or radiator grille. With the engine
on, the electric cooling fan will au-
tomatically start to run if the en-
gine coolant temperature is high
and/or the air conditioning is on.
DUse eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
DUsed engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
DDo not leave used oil within the
reach of children.
DDispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
DTake care when filling the brake
fluid reservoir because brake fluid
can harm your hands or eyes. If
fluid gets on your hands or in your
eyes, flush the affected area with
clean water immediately. If you still
feel uncomfortable with your hands
or eyes, go to the doctor.

Do−it−yourself service
precautions

DO−IT−YOURSELF MAINTENANCE: Introduction261
NOTICE
zRemember that battery and ignition
cables carry high currents or volt-
ages. Be careful not to accidentally
cause a short circuit.
zAdd only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based non−silicate,
non−amine, non−nitrite, and non−bo-
rate coolant with long−life hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water.
zIf you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging any parts
or paint.
zDo not allow dirt or anything else
to fall through the spark plug holes.
zDo not pry the outer electrode of a
spark plug against the center elec-
trode.
zUse only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
zIf you spill brake fluid, be sure to
wash it off with water to prevent it
from damaging any parts or paint.
zDo not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
zBe careful not to scratch the glass
surfaces with the wiper frames.
zWhen closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
DDo not cause a spark from the bat-
tery with tools.
DDo not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
DAvoid contact with eyes, skin or
clothes.
DNever ingest electrolyte.
DWear protective safety glasses when
working near the battery.
DKeep children away from the bat-
tery.
EMERGENCY MEASURES
DIf electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
DIf electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
DIf electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
DIf you accidentally swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of magne-
sia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.
The electricity stored in the battery will
discharge gradually even when the vehicle
is not in use, due to natural discharge
and the draining effects of certain electri-
cal appliances. If the vehicle is left for a
long time, the battery may discharge, and
the engine may be unable to start. (The
battery recharges automatically during
driving.)
The meanings of each caution symbol
on the top of the battery are as fol-
lows:
No smoking, no naked
flames, no sparks
Shield eyes
Keep away from children

Terminals
Hold−down clamp
Check the battery for corroded or loose
terminal connections, cracks, and a
loose hold−down clamp.
a. If the battery is corroded, wash it off
with a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose,
tighten their clamp nuts—but do not
overtighten.
c. Tighten the hold−down clamp only
enough to keep the battery firmly in
place. Overtightening may damage the
battery case.
NOTICE
zBe sure the engine and all accesso-
ries are off before performing main-
tenance.
zWhen checking the battery, remove
the ground cable from the negative
terminal (“−” mark) first and rein-
stall it last.
zBe careful not to cause a short cir-
cuit with tools.
zTake care no solution gets into the
battery when washing it.
