Checking and replacing fuses  
Type A fuses can be pulled out by using  
the pullout tool. The location of the pull−  
out tool is shown in the illustration.  
Type A  
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.  
Good  
Blown  
Only install a fuse with the amperage rat-  
ing designated on the fuse box lid.  
Type B  
If you do not have a spare fuse, in an  
emergency you can pull out the “PWR  
OUTLET” or “HEATER NO.2” fuse, which  
may be dispensable for normal driving,  
and use it if its amperage rating is the  
same.  
If the headlights or other electrical  
components do not work, check the  
fuses. If any of the fuses are blown,  
they must be replaced.  
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.

Blown  
See “Fuse locations” on page 430 in Sec-  
tion 71 for locations of the fuses.  
Type C  
Turn the engine switch 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 468 in Section 8 for the functions  
controlled by each circuit.  
It is a good idea to purchase a set of  
spare fuses and keep them in your ve-  
hicle for emergencies.

Adding washer fluid  
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.  
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.  
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.  
NOTICE  
Do not use engine antifreeze or any  
other substitute because it may dam-  
age your vehicle’s paint.  
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” or  
only slightly above the “LOW” level,  
add washer fluid.  
For vehicles sold in Canada—  
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.
