CAUTION
Vehicles with Display Audio system
Properly shielded a grounded cables and connectors must be used for
connection to host computer and/or peripherals in order to meet FCC
emission limits.
This transmitter must not be co-located or operated in conjunction with any
other antenna or transmitter.
This device complies with Part 15 of FCC Rules and Industry Canada
licence-exempt RSS standard(s). Operati on is subject to the following two
conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause
undesired operation of this device.
This equipment complies with FCC/IC radiation exposure limits set forth
for an uncontrolled environment and meets the FCC radio frequency (RF)
Exposure Guidelines in Supplement C to OET65 and RSS-102 of the IC
radio frequency (RF) Exposure rules. This equipment has very low levels
of RF energy that it deemed to comply without maximum permissive expo-
sure evaluation (MPE). But it is desirable that it should be installed and
operated keeping the radiator at least 7.9 in. (20 cm) or more away from
person’s body (excluding extremities: hands, wrists, feet and ankles).
Under Industry Canada regulations, this radio transmitter may only oper-
ate using an antenna of a type and maximum (or lesser) gain approved for
the transmitter by Industry Canada. To reduce potential radio interference
to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (e .i.r.p.) is not more than that nec-
essary for successful communication.
NOTICE
■ To prevent battery discharge
Do not leave the audio system on longer than necessary with the engine o\
ff.
■ To avoid damaging the audio system
Take care not to spill drinks or other fluids over the audio system.

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
Engine coolant
The coolant level is satisfactory if it is between the FULL and LOW
lines on the reservoir when the engine is cold.
Reservoir cap
FULL line
LOW line
If the level is on or below the
LOW line, add coolant up to the
FULL line.
■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.

444 4-3. Do-it-yourself maintenance
Radiator and condenserCheck the radiator and condenser and clear any foreign objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
Type A
The brake fluid level should be
between the MAX and MIN lines
on the reservoir.
MAX line
MIN line
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.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

540 5-2. Steps to take in an emergency
The engine has cooled down sufficiently.
The engine coolant temperature gauge indicates C.
Check the engine coolant level.
Look for obvious coolant leaks from the radiator, hoses and
under the vehicle.
Note that water draining from the air conditioning is normal if it has
been used.
Add engine coolant if required.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( P. 559)
Have the vehicle checked at your nearest Toyota dealer as soon as
possible.

When trouble arises

5-2. Steps to take in an emergency
■
Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
● Steam is coming from under the hood.
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 injury such as burns.
● Keep hands and clothing away from the fan and other belts while the
engine is running.
● Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
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.
