ItemsParts and toolsWARNING
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 fans and
engine drive belt.
●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter 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 and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fans or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fans may auto-
matically start to r un if the air con-
ditioning is on an d/or the coolant
temperature is high. ( P.308)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.

hybrid organic acid technology.
U.S.A.:
“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a
mixture of 50% coolant and 50%
deionized water. (Minimum tem-
perature: -31°F [-35°C])
Canada:
“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a
mixture of 55% coolant and 45%
deionized water. (Minimum tem-
perature: -44°F [-42°C])
For more details about coolant, con-
tact your Toyota dealer.
■If the coolant level drops within
a short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir caps, 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 sys-
tem.
Check the radiator and con-
denser and clear away any for-
eign objects.
If either of the above parts is
extremely dirty or you are not
sure of their condition, have
your vehicle inspected by your
Toyota dealer.
■Checking fluid level
The brake fluid and clutch fluid
level should be between the
“MAX” and “MIN” lines on the
tank.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap. ( P.376)
The cooling system may be under
pressure and may spray hot cool-
ant if the cap is removed, causing
serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight 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 it from damaging parts or
paint.
Checking the radiator and
condenser
WARNING
■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and
cause serious injuries, such as
burns.

7
When trouble arises
1Stop the vehicle in a safe
place and turn off the air con-
ditioning system, and then
stop the engine.
2 If you see steam: Carefully lift
the hood after the steam sub-
sides.
If you do not see steam:
Carefully lift the hood.
3 After the engine has cooled
down sufficiently, inspect the hoses and radiator core (radi-
ator) for any leaks.
Radiators
Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.

The coolant level is satisfac-
tory if it is between the
“FULL” and “LOW” lines on
the reservoir.

5 Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
If your vehicle over-
heats
The following may indicate
that your vehicle is over-
heating.
The engine coolant tem-
perature gauge ( P. 8 8 ) i s
in the red zone or a loss of
engine power is experi-
enced. (For example, the
vehicle speed does not
increase.)
 “High Coolant Temperature
Check Owner's Manual” is
shown on the multi-informa-
tion display.
 Steam comes out from
under the hood.

able.
6Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fans operate and to check
for coolant leaks from the
radiator or hoses.
The fans operate w hen the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fans are operating by
checking the fan sound and air flow.
If it is difficult to check these, turn
the air conditioning system on and
off repeatedly. (The fans may not
operate in freezing temperatures.)
7 If the fans are not operating:
Stop the engine immediately
and contact your Toyota
dealer.
If the fans are operating:
Have the vehicle inspected at
the nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf or a muffler)
away from the fans and belts.
Failure to do so may cause the
hands or clothing to be caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir caps while the engine and
radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the
engine has cooled down suffi-
ciently. 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 precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.
