CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle, leading to a serious accident.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Hold a rag under the end and pull the dipstick out.

Maintenance and care
Remove the oil filler cap, turning it counterclockwise.
Add engine oil slowly.
Checking the dipstick.
Reinstall the filler cap, turning it clockwise.
The approximate quantity of oil needed to raise the level between low and
full on the dipstick is indicated as follows:
1.6 qt. (1.5 L,
1.3 lmp. qt.)
■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing 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, when towing,
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 or 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.

LOW
If the level is on or below the
LOW line, add coolant up to the
FULL line.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil

Maintenance and care
■
If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with
long-life hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 F [-42 C])
For more details about engine coolant, contact your Toyota dealer.
CAUTION
■ 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 serious injuries, such as burns.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor stra ight 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 damage to parts or paint.

552 4-3. Do-it-yourself maintenance
Radiator and condenserCheck the radiator and condenser and clear any foreign objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the MAX and MIN lines
on the reservoir.
■ Adding fluid
Make sure to check the fluid type and prepare the necessary items.
CAUTION
■ When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
serious injuries, such as burns.
Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Rag or paper towel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
