Checking the battery status –  
– Instructions  
The meaning of the individual warning  
symbols on the top of the battery is as  
follows:  
WARNING  
BATTERY INSTRUCTIONS  
The battery produces hydrogen gas, which  
is flammable and explosive.  
Do not smoke, do not use  
open flames, avoid sparks  
• Be careful not to spark the battery by  
touching the tool.  
• Do not smoke or light matches near the battery.  
Protect your eyes  
The electrolyte contains poisonous and  
corrosive sulfuric acid.  
• Avoid contact with eyes, skin or  
clothing.

Battery acid  
• Never swallow the electrolyte.  
• Always use safety glasses when  
working near the battery.  
• Prevent children from getting into  
near the battery.  
EMERGENCY MEASURES  
Read the instructions for use  
Explosive gas  
• If the electrolyte gets into the eyes, rinse the  
eyes with clean water and seek medical help  
immediately. If possible, wash your eyes with  
water and a clean cloth or sponge also during  
the trip to the hospital.

when washing it.  
Before checking the battery, remove the battery  
cover. (See "– Engine Compartment Cover Removal"  
on page 361 in Chapter 7–1.)  
If the battery is disconnected or discharged, the power  
windows and sunroof may not operate automatically when  
the battery is reconnected, replaced or recharged, and the  
anti-entrapment function will not function properly. In these  
cases, you should normalize the operation of the power  
windows and sunroof - see "Power windows" on page 38  
and "Power sunroof" on page 56 in Chapters 1-2.  
Check the battery for corroded or loose terminal  
connections or a cracked or loose retaining clip.  
a. If the battery is corroded, rinse it with a solution of  
warm water and baking soda.  
Apply grease to the battery terminals to prevent  
further corrosion.  
b. If the pole extension connections are loose,  
tighten their terminals, but do not overtighten  
them.  
c. Tighten the retaining clip just enough to hold the  
battery firmly in place. Over-tightening the clamp can  
damage the battery body.  
After checking the battery, replace the battery cover.

– Checking the battery fluid  
There are two types of accumulators: maintenance  
type and maintenance-free type.  
Battery Maintenance Type –  
Upper line  
Bottom line  
Check the fluid level using the fluid level marks on the side of  
the accumulator.  
Maintenance-free battery type –  
Check the battery status using the indicator on the top  
of the battery.  
LEVEL CHECK USING LINES (MAINTENANCE  
BATTERY TYPE ONLY)  
The liquid (electrolyte) level must be between the  
upper and lower marks.  
When checking the fluid level, check all six cells, not just  
one or two.  
If the level is below the lower line, add distilled water.  
(See "REFILLING DISTILLED WATER" on page 389.)

If the headlights or other electrical  
components do not work, check the fuses.  
If any of the fuses are blown, they must be  
replaced.  
Fuse Locations - See "Fuse Locations" on page  
363 in Chapter 7–1.  
Before checking the fuses, remove the  
engine compartment covers. (See "–  
Removing Engine Compartment Covers"  
on page 361 in Chapter 7–1.)  
Turn off the ignition and malfunctioning components.  
Pull out the suspect fuse and check it.  
Gasoline engine  
Determine which fuse might be faulty.  
The circuit name for each fuse is displayed on  
the fuse box lid. The functions of the individual  
electrical circuits are given on page 420 in  
chapter 8.  
Remove the type A fuses with a puller. The  
location of the extractor is shown in the figure.  
If you are not sure which fuse is blown, try  
replacing the probably faulty fuse with one that  
you know is good.  
If one of the fuses is blown, insert a new  
fuse into the terminal.  
Only install a fuse that has the current rating  
marked on the fuse box cover.  
Diesel engine  
If you don't have a spare fuse, in an emergency  
you can pull out the "CIG" or "DOME" fuses,  
which are expendable in normal driving, and  
use them if they have the same current rating.  
If you do not have a fuse of the same current  
rating, use another one that is weaker but as  
close to the required rating as possible. If the  
current range is lower than you need, the fuse  
may blow again, but this does not signal  
anything wrong. Be sure to get the correct fuse  
as soon as possible and return it to its original  
location.  
It is a good idea to purchase a set of spare fuses and  
keep them in the vehicle in case of an emergency.

Refilling the washer fluid  
If the new fuse blows immediately after replacement, the  
problem is in the electrical system.  
Have the system repaired as soon as possible by any  
authorized Toyota dealer or service center, or another  
properly qualified and equipped professional.  
WARNING  
Never use a fuse with a higher current rating or  
any other object in place of the fuse, as this could  
result in significant damage and the possibility of  
a fire.  
If none of the washers are working, the washer tank  
may be empty. Top up the washer fluid.  
Loosen the tank cap. Hold your finger on the hole in the  
middle and lift the cap. Check the liquid level in the tube  
attached to the cap. If the fluid level is extremely low,  
add washer fluid.  
You can use ordinary water for the washers. However,  
in areas where temperatures frequently drop below  
freezing, use a washer fluid containing antifreeze. You  
can get this product from any authorized dealer or Toyota  
service center or from another properly qualified and  
equipped specialist. Follow the manufacturer's instructions  
when mixing the solution with water.  
NOTICE  
Do not use engine cooling antifreeze or any other  
substitute as this could damage the vehicle's  
paintwork.

Replacing light bulbs -  
Before replacing the bulbs of the headlights, parking  
lights and front turn signals, remove the engine  
compartment covers. (See "– Engine Compartment  
Cover Removal" on page 361 in Chapter 7–1.)  
• Do not disassemble, repair or remove low  
beam bulbs, connectors, power circuits and  
related components. Doing so may result in  
electric shock and serious injury or death. For  
headlight repair, including bulb replacement  
and disposal, contact any authorized Toyota  
The pictures on the following pages serve as a guide on  
how to make the bulbs accessible. Always make sure the  
ignition and lights are off when changing the bulb. Use  
only bulbs with the wattage shown in the table.  
dealer or service center, or another properly  
qualified and equipped professional.  
The turn signals on the exterior mirrors consist of a  
number of LEDs. If any LED burns out, take the vehicle to  
any authorized Toyota dealer or workshop, or another  
properly qualified and equipped technician, and have the  
light replaced.  
NOTICE  
u When reinstalling all the covers, securely install  
the screws and clips that were removed to replace  
the bulbs in their original positions. Failure to do  
so may damage the vehicle.  
WARNING  
• Do not replace bulbs when they are  
hot to avoid burns.  
u Use only the type of bulbs listed  
in the list.  
• Halogen bulbs are filled with  
compressed gas and require special  
handling. Bulbs may crack or break  
if scratched or dropped.  
Inside the parabolas of the external lights, e.g. in the  
headlights, the headlight glasses may fog up temporarily  
in rain, humidity or when washing the car. This is not a  
problem because there is a temperature difference  
between the ambient air and the inside of the headlight  
Hold the bulb only by its plastic or metal body.
