2010 TOYOTA HIGHLANDER engine

442 4-3. Do-it-yourself maintenance
■Recommended viscosity (2.7 L 4-cylinder (1AR-FE) engine)
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE
0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
■ Recommended viscosity (3.5 L V6 (2GR-FE) engine)
Without towing package
SAE 5W-20 is the best choice for
good fuel economy, and good
starting in cold weather.
With towing package SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not avail-able, SAE 10W-30 oil may be
used. However, it should be
replaced with SAE 5W-30 at
the next oil change.

How to read oil container labels
Some oil containers are labeled with ILSAC certification marks that
help you to select the proper oil.
Oil identification mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certifica-
tion Mark is added to some oil
containers to help you select the
oil you should use.
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
● Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per
1000 km)
● If your vehicle consume more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600
miles (1000 km), contact your Toyota dealer.
■ Changing the engine oil (U.S.A. only)
To reset the oil change system, follow the procedure below:
Vehicles without smart key system
Set the engine switch to the “LOCK” position with the trip meter A
reading shown. ( P. 188)
While pressing the trip meter reset button, set the engine switch to
the “ON” position.

444 4-3. Do-it-yourself maintenance
Vehicles with smart key systemSet the “ENGINE START STOP” switch OFF with the trip meter A
reading shown. ( P. 188)
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to the IGNITION ON mode.
Without multi-information display: Continue to press and hold the
button until the trip meter displays “000000”.
With multi-information display: Continue to press and hold the but-
ton until “COMPLETE” appears on the multi-information display.
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.
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, as 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.

Maintenance and care
Engine coolant
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”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.

446 4-3. Do-it-yourself maintenance
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler 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 coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.
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.

Maintenance and care
Radiator and condenser
Check the radiator and condenser, and clear any foreign objects.
If either of the above parts are extremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
Vehicles without smart key system: The electric cooling fans may keep rotat-
ing for about 3 minutes after the engine switch is turned to the “LOCK” posi-
tion.
With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position when
working near the electric cooling fan or radiator grille.
Vehicles with smart key system: The electric cooling fan may keep rotating
for about 3 minutes even after the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. Be sure the “ENGINE START STOP” switch
is OFF when working near the electric cooling fans or radiator grille.
