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.

NOTICE
⬛When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture 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 pr event it from damaging parts or paint.
Radiator and condenser
Check the radiator and condenser and clear away any foreign objects. If
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
on the tank.
⬛Adding fluid
Make sure to check the fluid type and prepare the necessary item.

⬛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 meanings of each caution symbol on the top of the battery are as fol-
lows:

⬛Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following 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 dis-
connecting the charger cables to the battery.
WARNING
⬛Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and expl osive. To reduce the risk of death or
serious injury, take the following precautions while working on or near the bat-
tery:
⚫Do not cause sparks by touching the battery terminals with tools.
⚫Do not smoke or light a match near the battery.

Never recharge the battery while the engi ne is running. Also, be sure all acces-
sories are turned off.
⬛When adding distilled water
Avoid overfilling. Water spilled during battery recharging may cause corrosion.
Washer fluid
⬛Inspection procedure
Check the liquid surface with your
eyes from the side of the washer
tank.
⬛Refill procedure
Remove the cap from the washer
tank and dilute the fluid by referring
to the freezing temperature shown

WARNING
⬛When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid con-
tains alcohol and may catch fire if spilled on the engine, etc.
NOTICE
⬛Do not use any fluid other than washer fluid
Do not use soapy water or engine an tifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as
damaging the pump leading to proble ms of the washer fluid not spraying.
⬛Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures list ed on the label of the washer fluid bot-
tle.

Tire rotation
Rotate the tires in the order shown.
To equalize tire wear and help exte nd tire life, Toyota recommends that
tire rotation is carried out appr oximately every 5000 km (3000 miles).

Tire pressure warning system✽
Your vehicle is equipped with a tire pressure warning system that uses tire
pressure warning valves and transmitters to detect low tire inflation pres-
sure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (➞P. 382)
Installing tire pressure warning valves and transmitters
(vehicles with a tire pressure warning system)
When replacing tires or wheels, tire pressure warning valves and transmit-
ters must also be installed.
When new tire pressure warning valv es and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Toyota
dealer. ( ➞P. 329)
