Air conditioning system
Adjusting the settings■ Adjusting the temperature setting
Turn the temperature control dial clockwise (warm) or counter-
clockwise (cool).
If is not pressed, the system will blow ambient temperature air or
heated air.
For quick cooling, turn the temperature control dial to the MAX A/C posi-
tion. The air conditioning will automatically turn on and the air intake
selector will be set to recirculated air mode.
■ Adjusting the fan speed
Turn the fan speed control dial clockwise (increase) or counter-
clockwise (decrease).
Set the dial to OFF to turn the fan off.

• The shift lever is in N and the clutch pedal is not depressed.(manual transmission)
A maximum capacity of 400W can only be restored by turning
the power outlet main switch off and then on again under condi-
tion described above.
● The maximum capacity is 120 VAC/100 W when the following
condition applies:
• The shift lever is moved to any positions other than P and N.
(automatic transmission)
• The clutch pedal is depressed. (manual transmission)
■ The power outlet can be used when
The engine is started.
■ The indicator light changes accord ing the maximum available capacity,
as follows:
■ When the power outlet is in operation
The sound of the cooling fan may be heard from the front console box. This
is normal and does not indicate a malfunction.
■ If the engine is started with th e power outlet main switch on
The maximum capacity of the power supply may decrease to below the stan-
dard, or may be cut off completely, even when the vehicle is stationary.

402 4-3. Do-it-yourself maintenance
CAUTION
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 engine
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 rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
■ When working near the cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the cooling fan may automatically start to run if
the air conditioning is on and/or the coolant temperature is high.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Maintenance and care
■
If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with
long-life hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 F [-42 C])
For more details about engine coolant, contact your Toyota dealer.
CAUTION
■ 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 engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct 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 damage to parts or paint.

Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
●When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
NOTICE
■To prevent damaging the vehicle (vehicles with a manual transmission)
Do not pull- or push-start the vehicle, because the three-way catalytic con-
verter may overheat and become a fire hazard.
■ When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan
or any of the belts when connecting or disconnecting them.

5-2. Steps to take in an emergency
If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system, and then stop the engine.
If you see steam: Carefully lift the hood after the steam subsides completely.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory if
the reservoir level is between the
“FULL” and “LOW” lines on the
reservoir.Reservoir
“FULL”
“LOW”
Radiator cap
The following may indicate that your vehicle is overheating.
● The needle of the engine co olant temperature gauge (P. 145)
enters the red zone or a loss of engine power is experienced.
(For example, the vehicl e speed does not increase.)
● Steam comes out from under the hood.

5-2. Steps to take in an emergency
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine to check that the radiator cooling fan oper-
ates and check for coolant leak
s from the radiator or hoses.
If the fan is not operating: Stop the engine immediately and contact your Toyota
dealer.
If the fan is operating: Have the vehicle inspected at the nearest Toyota dealer.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.

510 5-2. Steps to take in an emergency
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additives.
