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.
If any washer does not work or low
windshield washer fluid level warning
light* comes on, the washer tank may
be empty. Add washer fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below 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.
*: When equippedThe following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
CAUTION
To prevent from 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.
NOTICE
Only use a bulb of the listed type.
