To defog or defrost the outside rear
view mirrors, push the switch.
The key must be in the “ON” position.
The heater panels in the outside rear view
mirrors will quickly clear the mirror sur-
faces. An indicator light will illuminate to
indicate the mirror heaters are operating.
Push the switch once again to turn the
mirror heaters off.
The system will automatically shut off af-
ter the mirror heaters have operated about
15 minutes.
CAUTION
Since the mirror surfaces can get hot,
do not touch them when the switch
is on.
Make sure you turn the mirror heaters off
when the mirror surfaces are clear. Leav-
ing the mirror heaters on for a long time
could cause the battery to discharge, es-
pecially during stop−and− go driving. The
mirror heaters are not designed for drying
rain water or for melting snow.
If the outside rear view mirrors are heavi-
ly coated with ice, use a spray de −icer

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
