WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■ When working on the engine compartment
● Keep hands, clothing and tools away from the moving fan and eng ine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or ra gs, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGN ITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 466)
■ When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, flui d spray, etc.
from getting in your eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

Maintenance and care
The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
“F”
“L”
If the level is on or below the “L”
line, add coolant up to the “F” line.
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-bora te coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50 % coolant and 50 %
deionized water. (Minimum temperature: -31 F [-35 C])
For more details about engine coolant, contact your Toyota deal er.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, radiator cap,
drain cock and water pump. If you cannot find a leak, have your Toyota dealer
test the cap and check for leaks in the cooling system.

WARNING
■ When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The cor rect mixture of
water and antifreeze must be used to provide proper lubrication , corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damage to parts or paint.

Check the radiator and condenser and clear any foreign objects.
If either of the above parts is extremely dirty or you are not sure of
their condition, have your vehic le checked by your Toyota deale r.
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
“MAX” line
“MIN” line
■Adding fluid
Make sure to check the fluid ty pe and prepare the necessary ite m.
■Refilling brake fluid
Turn the engine switch off.
Depress the brake pedal more than 40 times.
Remove the reservoir cap by hand. Add brake fluid up to the
“MAX” line.
If you do not follow the procedure above, the reservoir may ove rflow.

When trouble arises
7-2. Steps to take in an emergency
If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiat or) for any leaks.
Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The following may indicate that your vehicle is overheating.
● The needle of the engine c oolant temperature gauge (P. 93)
enters the red zone or a loss of engine power is experienced. ( For
example, the vehicle s peed does not increase.)
● Steam is coming from under the hood.

Radiator cap
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the ai r conditioning system on to check
that the air conditioning condenser cooling fans operate and to
check for coolant l eaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating b y checking the
fan sound and air flow. If it is difficult to check these, turn the air condition-
ing system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle ins pected at the nearest Toyota dealer.
