TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The key must be in the “ON” position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.To turn on the emergency flashers,
push the switch.
All the turn signal lights will flash. To turn
them off, push the switch once again.
Turn on the emergency flashers to warn
other drivers if your vehicle must be
stopped where it might be a traffic hazard.
Always pull as far off the road as pos-
sible.
The turn signal light switch will not work
when the emergency flashers are operat-
ing.
NOTICE
To prevent the battery from being dis-
charged, do not leave the switch on
longer than necessary when the en-
gine is not running.

The 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 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.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens 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 lens, just like the
windshield fogged up in the rain. However,
if there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer. Light bulbsBulb
