WARNING
●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, consult a doctor.
■When working near the electric cooling fan or radiator grille
Be sure the engine switch is OFF. With the engine switch in ON, the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. ( P.357)
■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.

WARNING
■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

Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.442)
■Coolant selection
Only use “Toyota Super Long Life Cool- ant” 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.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-ized water. (Minimum temperature: -
35°C [-31°F])
For more details about coolant, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap. ( P.443)
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.

from around the front wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide traction.
4 Restart the engine.
5 Shift the shift lever to D or R
(Multidrive) or 1 or R (manual

WARNING
●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 fan and belts. Failure 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:
