Terminals

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 auxiliary battery is disc onnected
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 42 and “Back door” on page 41.
Before you disconnect the auxiliary bat-
tery, confirm the shift position is “P” and
apply the parking brake completely. After you reconnect the auxiliary 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.

302
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

303
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 279 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 316 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.

304
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.
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 high voltage sock-
et when the headlight turns on.
20000 V is momentarily generated
and may cause severe injury by
electric shock.
Do not disassemble, repair or take
apart the headlight bulbs, connec-
tor, power supply circuits and ro-
tate components. Or you may be
injured by electric shocks. Call your
dealer when the headlights fail to
work or have to be replaced or dis-
posed of.
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.
