Adding engine oil

If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.

Make sure to check the oil type and prepare the items needed
before adding oil.

Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.

■

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

WARNING

■

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.

NOTICE

■

To prevent serious engine damage
Check the oil level on a regular basis.

■

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.

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.

■

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.

Engine coolant

346

6-3. 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.

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 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.

Radiator and condenser

WARNING

■

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.

6-3. Do-it-yourself maintenance

Add brake fluid slowly while checking the fluid level.
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 cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.

Fluid type

FMVSS No.116 DOT 3 or SAE J1703;
FMVSS No.116 DOT 4 or SAE J1704 brake fluid

Item

Clean funnel

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, 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)

●

The engine may not start. Follow the procedure below to initialize the sys-
tem.

Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.

●

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 disconnecting the battery. Take extra care when connecting the bat-
tery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.

■

Emergency measures regarding electrolyte

●

If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.

●

If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.

●

If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.

●

If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.

■

When there is insufficient battery fluid

Washer fluid

WARNING

■

When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid
contains 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 antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
