WA R N I N G
■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 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 and rags, in the engine compartment.
●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 work-
ing on the battery. It contains poi- sonous and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and dam-
age 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, con- sult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in ON, the electric cooling fans may automati-
cally start to run if the air conditioning
is on and/or the coolant temperature is high. (P.298)
■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 fil-
ter
Driving with the air cleaner filter removed may cause excessive
engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

vals.
●When the engine is new, for example
directly after purchasing the vehicle or after replacing the engine
●If low quality oil or oil of an inappropri-ate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating fre-
quently
●When leaving the engine idling for a
long time, or when driving frequently through heavy traffic
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
engine is cold.
■Engine coolant reservoir

“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
( P.362)
■Coolant selection
Only use “TOYOTA Genuine 50/50
Pre-mixed Super Long Life Coolant BLUE” or a similar high quality ethylene
glycol based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.

■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as
inflammation and skin cancer, so
care should be taken to avoid pro- longed and repeated contact. To
remove used engine oil from your
skin, wash thoro ughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner.
Do not dispose of used oil and fil-
ters in household trash, in sewers or onto the ground. Call any author-
ized Toyota dealer or repairer, or
another duly qualified and equipped professional, service station or auto
parts store for information concern-
ing recycling or disposal.
●Do not leave used engine oil within
the reach of children.
NOTICE
■To prevent serious engine dam-
age
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on
the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dipstick
every time you refill the vehicle.
●Be sure the engine oil filler cap is
properly tightened.

For more details about engine coolant,
contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■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 system.
Check the radiator and condenser
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that there
are no loose connections, cracks,
or loose clamps.
Hold-down clamp
Terminals
■Checking battery fluid
Check that the level is between the
“UPPER LEVEL” and “LOWER
LEVEL” lines.

■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
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 correct mix-
ture 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.

Cooling fans
If a large amount of coolant leaks,
immediately contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

5 Add engine coolant if necessary.
Water can be used in an emergency if
engine coolant is unavailable.
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fans
operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air condi-
tioning system is turned on immediately
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 repea tedly. (The fans
may not operate in freezing tempera-
tures.)
7 If the fans are not operating:
Stop the engine immediately
and contact any authorized
Toyota retailer or Toyota author-
ized repairer, or any reliable
repairer.
If the fans are operating: Have
the vehicle inspected at the
nearest any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

■When inspecting under the hood
of your vehicle
Observe the following precautions. Failure to do so ma y result in serious
injury such as burns.

3647-2. Steps to take in an emergency
1Stop the engine. Set the parking
brake and shift the shift lever to
P (automatic transmission) or N
(manual transmission).
2 Remove the mud, snow or sand
from around the rear wheels.
3 Place wood, stones or some
other material under the rear
wheels to help provide traction.
4 Restart the engine.
5 Shift the shift lever to D or R
(automatic transmission) or 1 or
R (manual transmission) and
release the parking brake. Then,
while exercising caution,
depress the accelerator pedal.
■When it is difficult to free the vehi- cle
Press the switch to turn off TRC.

●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.
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler)
away from the fans and belts. Fail-
ure to do so may cause the hands or clothing to be caught, resulting in
serious injury.
●Do not loosen the coolant reservoir
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 sufficiently. 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 additive.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
