Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW” lines
on the reservoir when the engine is cold.
a Reservoir cap
b “FULL” line
c “LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
(➞ P. 412)
⬛Coolant selection
Only use “Toyota Super Long Life Coolan t” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid org anic 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 engine coolant, contact your Toyota Genuine dealer.
⬛If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock and
water pump.
If you cannot find a leak, have your Toyo ta dealer test the cap and check for
leaks in the cooling system.
WARNING
⬛When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing seri ous injuries, such as burns.
⬛When replacing the coolant
To avoid coolant spilling on the altern ator, do not remove the upper radiator
hose from engine side (remove from the radiator side). Coolant spilled on the
alternator will cause corrosion of the coil and a fire.

either of the above parts is extremel y dirty or you are not sure of their
condition, have your vehicle inspected by your Toyota dealer.
WARNING
⬛When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.
Brake fluid
⬛Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines

⬛Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can ca use a dangerous loss of braking efficiency.
Use only newly opened brake fluid.
WARNING
⬛When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage 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.
NOTICE
⬛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
out or when the fluid level in the accumulator is high.
If the reservoir needs frequent ref illing, there may be a serious problem.
Battery
Check the battery as follows.
⬛Caution symbols✽

the ground cable.
⚫Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
WARNING
