Maintenance and care
WA R N I N G
●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,
consult 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.476)
■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.

■Engine coolant reservoir
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.
( P.560)
■Intercooler coolant reservoir
The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the engine is
cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.560)
■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.
NOTICE
■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.

4767-3. Do-it-yourself maintenance
Check the radiator, condenser and
intercooler 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 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.
Terminals
Hold-down clamp
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the charger is off when connecting and disconnecting the
charger cables to the battery.
■After recharging/reconnecting the
battery (vehicles with a smart entry & start system)
●Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the
battery. If this happens, use the wire- less remote control or the mechanical
key to lock/unlock the doors.
●Start the engine with the engine
switch in ACC. The engine may not

■When the engine is hot
Do not remove the engine coolant
reservoir cap and the intercooler cool- ant reservoir cap.
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.

denser and intercooler

operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air condi-
tioning system is tu rned 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 r epeatedly. (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 may result in serious
injury such as burns.
●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.
