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 fille r cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.

■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 ne ed to be
refilled in between oil maintenance intervals.
● When the engine is new, for example directly after purchasing t he 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

The coolant level is satisfactory if it is between the “FULL” a nd “LOW”
lines on the reservoir wh en 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-bora te coolant with
long-life hybrid organic acid technology.
For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture o f 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 deal er.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir ca ps, 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

3666-3. 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 vehic le inspected by your Toyota dea ler.
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 cor rect 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 p arts or paint.
Radiator and condenser
WARNING
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and c ause seri-
ous injuries, such as burns.

WARNING
■ When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damag e
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 t he brake pads
wear out or when the fluid level in the accumulator is high.
However, if the reservoir needs frequent refilling, there may b e a serious
problem. Have the vehicle inspected at your Toyota dealer as soon as pos-
sible.
