DO-IT-YOURSELF MAINTENANCE - Electrical components -> Replacing light bulbs for Your Toyota Prius 4 Door First Generation (1997-2003)

Adding washer fluid  
Replacing light bulbs—  
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.  
NOTICE  
Do not use engine antifreeze or any  
other substitute because it may dam-  
age your vehicle’s paint.  
CAUTION  
D To prevent yourself from burning,  
do not replace the light bulbs while  
they are hot.  
D 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.  
If any washer does not work, the wash-  
er tank may be empty. Check the wash-  
er fluid level on the level gauge. If the  
washer fluid level is below “LOW”, add  
washer fluid.  
FULL” on the side of the washer tank  
NOTICE  
indicates the full level of washer fluid. Do  
not refill washer fluid over this level.  
Only use a bulb of the listed type.  
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.

—Headlights  
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 fogged 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.
