TOYOTA PRIUS 2006 2.G Owners Manual

411
CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tire, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
Replacing wheels

412
When installing aluminum w
heels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.

CAUTION
12 VOLT BATTERY PRECAUTIONS
When the 12 volt battery must be re-
placed, use the Prius designated bat-
tery.
The 12 volt battery produces flam-
mable and explosive hydrogen gas.
Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES
If electrolyte gets in your eyes,
flush your eyes with clean water
and get immediate medical atten-
tion. If possible, continue to apply
water with a sponge or cloth while
en route to the medical office.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burn, get medical
attention immediately.
If 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.
If 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.

Open the back door. Remove the lug-
gage storage box and 12 volt battery
cover.
If the back door does not open, see “If
you cannot operate back door opener” on
page 376.

Terminals
Ground
cableHold−down clamp
Check the battery for corroded or loose
terminal connections, cracks, or loose
holddown 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
 Be sure the hybrid system and all
accessories are off before perform-
ing maintenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“–” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
If the 12 volt battery is disconnected or
run down, the power window and back
door may not operate automatically and
the jam protection function will not func-
tion correctly and does not open the back
door after you reconnect, replace or re-
charge the battery. In any of these cases,
you should normalize each system. To
normalize them, see “Power windows” on
page 43 and “Back door” on page 42.
Before you disconnect the 12 volt battery,
confirm the shift position is “P” and apply
the parking brake completely. After you reconnect the 12 volt battery,
shift the shift lever to “N” and confirm the
shift position is “N” when the “IG
−ON”
mode is enabled.
After connecting the cables, the hybrid
system may not start by pushing the
“POWER” switch. In that case, push it
once again.

416
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Make sure the power switch on the recharger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (3.5A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery with the
hybrid system on. Also, be sure all
accessories are turned off.

Checking and replacing fuses

417
83p004b
If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See “Fuse locations” on page 393 for
locations of the fuses.
Turn the hybrid system and inoperative
component off. Pull the suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
page 430 for the functions controlled by
each circuit.Type A fuses can be pulled out by the
pull
−out tool. The location of the pull −out
tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the “DOME”
or “OBD II” fuse, which may be dispens-
able for normal driving, and use it if its
amperage rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. If the amperage
is lower than that specified, the fuse
might blow out again. but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies. If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.

418
If any washer does not work, the wash-
er tank may be empty. Add washer
fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below the freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer ’s directions for how much to
mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the hybrid system and
light switch are off. Use bulbs with the
wattage ratings given in the table.
The stop lights and high mounted stoplight
consist of a number of LEDs. If any of
LEDs burn out, take your vehicle to your
Toyota dealer to have the light replaced.
If two or more LEDs in a stop light burn
out, your vehicle may not conform to local
laws (SAE).
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
Vehicles with discharge headlights—
Do not touch the highintensity dis-
charge headlight’s high voltage
socket when the headlights are
turned on. An extremely high volt-
age of 20,000V will be discharged
and could result in serious injury
or death by electric shock.
Do not attempt to take apart or re-
pair the headlight bulbs, connec-
tors, power supply circuits, or re-
lated components. Doing so could
result in electric shock and serious
injury or death. Call your Toyota
dealer for headlight repair or servic-
ing, including replacement of bulbs
and bulb disposal.
NOTICE
Only use a bulb of the listed type.

The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lense becomes wet in the rain
or in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lense, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lense, or if there is water
pooled inside the light, contact your
Toyota dealer.Light bulbsBulbNo.WTy p e
