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
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.
ItemsParts and tools●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is OFF.
With the engine switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.347)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
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
U.S.A.:
“Toyota Super Long Life Coolant” is
a mixture of 50% coolant and 50%
deionized water. (Minimum tem-
perature: -31°F [-35°C])
Canada:
“Toyota Super Long Life Coolant” 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 condi-
tion, have your vehicle
inspected by your Toyota dealer.
■Checking fluid level
The brake 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.
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 d amaging 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.

4237-2. Steps to take in an emergency
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.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan or engine drive belt.
■When connecting jumper
cables
Make sure to connect jumper
cables to the specified terminals
and connecting point. Failure to
do so may adversely affect the
electronic devices or damage to
them.
If your vehicle over-
heats
The following may indicate
that your vehicle is over-
heating.
 The engine coolant tem-
perature gauge ( P.76, 79)
is in the red zone or a loss
of engine power is experi-
enced. (For example, the
vehicle speed does not
increase.)
 “Engine Coolant Temp High
Stop in a Safe Place See
Owner’s Manual” is shown
on the multi-information dis-
p l a y.
 A loss of engine power is
experienced. (For example,
the vehicle speed does not
increase.)
 Steam comes out from
under the hood.
Correction procedures

4247-2. Steps to take in an emergency
3After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radi-
ator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately cont act your Toyota
dealer.
4 The coolant level is satisfac-
tory if it is between the “MAX”
and “MIN” lines on the reser-
voir.
Reservoir cap
“MAX” line
“MIN” line
5 Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able. If water was added in an emer-
gency, have the vehicle inspected
at your Toyota dealer as soon as
possible.
6
Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fan operates and to check
for coolant leaks from the
radiator or hoses.
The fan operates when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fan is operating by check-
ing the fan sound and air flow. If it is
difficult to check these, turn the air
conditioning system on and off
repeatedly. (The fan may not oper-
ate in freezing temperatures.)
7If 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.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. Failure to do so may result
in serious injury such as burns.

4257-2. Steps to take in an emergency

When trouble arises
1Stop the engine. Set the
parking brake and shift the
shift lever to P.
Do not press the shift lever button
after shifting the shit position to P.
2Remove the mud, snow or
sand from around the front
wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide trac-
tion.
4 Restart the engine.
5 Shift the shift lever to D or R
and release the parking
brake. Then, while exercising
caution, depress the acceler-
ator pedal.
■When it is difficult to free the
vehicle
Press the switch to turn off
TRAC.
WARNING
●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 scarf or a muffler)
away from the fan and belts.
Failure to do so m ay cause the
hands or clothing to be caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir cap 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.
If the vehicle becomes
stuck
Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:
