■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, when towing
(except for South Africa), or when driving while accelerating or decelerating
frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
■ After changing the engine oil (diesel engine only)
The engine oil maintenance data should be reset. Perform the following pro-
cedures:
Switch the display to the trip meter “A” when the engine is running.
( P. 93)
Turn the engine switch to the “LOCK” position (vehicles without a smart
entry & start system) or off (vehicles with a smart entry & start system).
Vehicles without a smart entry & start system:
While pressing the display change button ( P. 93), turn the engine
switch to the “ON” position (do not start the engine because reset mode
will be canceled). Continue to press and hold the button until the trip
meter displays “000000”.
Vehicles with a smart entry & start system:
While pressing the display change button ( P. 93), turn the engine
switch to the IGNITION ON mode (do not start the engine because other-

Call any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, 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.

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. 493)
■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.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35 C [-31F])
For more details about coolant, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■ 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 any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional test the cap and check for
leaks in the cooling system.

Check the radiator, condenser and intercooler and clear away any for-
eign objects.
If any of the above parts is extremely dirty or you are not sure of their
condition, have your vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
WARNING
■ When the engine is hot
Do not remove the radiator cap (gasoline engine), or the engine coolant res-
ervoir cap (diesel engine).
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 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 it from damaging parts or paint.
Radiator, condenser and intercooler
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.

■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 entry &
start system)
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less 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 disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
WARNING
■ Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
● Do not cause sparks by touching the battery terminals with tools.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the battery.
● Keep children away from the battery.

You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Even if you decide to drain it yourself, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
The water in the fuel filter needs to be drained if the fuel filter warning
light comes on. (P. 442)
Turn the engine switch to the “LOCK” position (vehicles without a
smart entry & start system) or off (vehicles with a smart entry &
start system).
Place a small tray under the drain plug to catch the water and any
fuel that comes out.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Operate the priming pump until
fuel begins to run out.
After draining, tighten the drain plug by hand.
