WARNING
●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 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.261)
■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.

Reservoir cap
FULL line
LOW line
If the level is on or below the (LOW)
line, add coolant up to the (FULL)
line. ( P.339)
■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 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.
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.
Checking the radiator, con-

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
■Checking battery fluid
Check that the level is between the
“Upper line” and “Lower line” lines.
“Upper line”
“Lower line”
Add distilled water before the fluid level
drops below the “Lower line”.
■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 power switch on the
charger is off when connecting and disconnecting the charger cables to the battery.
■After recharging/reconnecting the
battery (vehicles with 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
start with the engine switch turned off. However, the engine will operate nor-mally from the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
