nEngine 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.
lWhen the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
l If low quality oil or oil of an inappropriate viscosity is used
l When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
l When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
WARNING
n Used engine oil
lUsed 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.
l 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 Scion dealer, service station or auto parts store for information
concerning recycling or disposal.
l Do not leave used engine oil within the reach of children.
NOTICE
nTo prevent serious engine damage
Check the oil level on a regular basis.
n When replacing the engine oil
lBe careful not to spill engine oil on the vehicle components.
l Avoid overfilling, or the engine could be damaged.

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. ( P. 288)
nCoolant 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 Scion dealer.
n 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 Scion dealer test the cap and check for
leaks in the cooling system.

WARNING
nWhen 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
nWhen 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.
n If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

nBrake 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.
WARNING
nWhen 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
nIf 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 Scion dealer as soon as possi-
ble.
