■Engine oil consumption

A certain amount of engine oil will be consumed while driving. In the following

situations, oil consumption may increase, and engine oil may need to be

refilled in between oil maintenance intervals.

●When the engine is new, for example directly after purchasing the vehicle or

after replacing the engine

●If low quality oil or oil of an inappropriate viscosity is used

●When driving at high engine speeds or with a heavy load, or when driving

while accelerating or decelerating frequently

●When leaving the engine idling for a long time, or when driving frequently

through heavy traffic

CAUTION

■Used engine oil

●Used engine oil contains potentially harmful contaminants which may

cause skin disorders such as inflammation and skin cancer, so care

should be taken to avoid prolonged and repeated contact. To remove used

engine oil from your skin, wash thoroughly with soap and water.

●Dispose of used oil and filters only in a safe and acceptable manner. Do

not dispose of used oil and filters in household trash, in sewers or onto the

ground.

Call your Toyota dealer, service station or auto parts store for information

concerning recycling or disposal.

●Do not leave used engine oil within the reach of children.

Engine coolant

7-3. Do-it-yourself maintenance

The coolant level is satisfactory if it is between the “F” and “L” lines on

the reservoir when the engine is cold.

Reservoir cap

1

“F” line

2

“L” line

3

If the level is on or below the “L”

line, add coolant up to the “F” line.

(P. 536)

■Coolant selection

Only use “Toyota Super Long Life Coolant” 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.

For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool-

ant and 50% deionized water. (Minimum temperature: -31F

[-35C])

For Canada: “Toyota Super Long Life Coolant” is a mixture of 55% cool-

ant and 45% deionized water. (Minimum temperature: -44F

[-42C])

For more details about engine coolant, contact your Toyota dealer.

■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 your Toyota dealer test the cap and check for

leaks in the cooling system.

7-3. Do-it-yourself maintenance

CAUTION

■When the engine is hot

Do not remove the engine coolant reservoir cap or the radiator cap.

(P. 538)

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 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 prevent it from damaging parts or paint.

7-3. Do-it-yourself maintenance

Check the radiator and condenser and clear away any foreign objects.

If either of the above parts is extremely dirty or you are not sure of

their condition, have your vehicle inspected by your Toyota dealer.

CAUTION

■When the engine is hot

Do not touch the radiator or condenser as they may be hot and cause seri-

ous 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.

■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, see 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.

However, if the reservoir needs frequent refilling, there may be a serious

problem. Have the vehicle inspected at your Toyota dealer as soon as pos-

sible.

■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.

■After recharging/reconnecting the battery (vehicles with a smart key sys-

tem)

●Unlocking the doors using the smart key system may not be possible imme-

diately after reconnecting the battery. If this happens, use the wireless

remote control or the mechanical key to lock/unlock the doors.

●Start the engine with the engine switch in ACCESSORY mode. The engine

may not start with the engine switch turned off. However, the engine will

operate normally 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 disconnected. Make sure to turn off the engine

before disconnect the battery. 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 your Toyota

dealer.
