● Used 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.
● 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 any authorized Toyota reta iler or Toyota authorized repairer,
or any reliable repairer, 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

The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
■Engine coolant reservoir
If the level is on or below the “L” line, add coolant up to the “F” line.
( P. 678)
■Intercooler coolant reservoir (if equipped)
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F”
line. ( P. 678)
■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])

Maintenance and care
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, intercooler
coolant reservoir cap (if equipped), drain cock and water pump. If you cannot
find a leak, have any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer test the cap and check for leaks in the cooling system.
Check the radiator, condenser and Intercooler coolant radiator/inter-
cooler and clear away any foreign objects. If any of the above parts is
extremely dirty or you are not sure of their condition, have your vehi-
cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
■ When the engine is hot
Do not remove the radiator cap (if equipped), the engine coolant reservoir
cap or intercooler coolant reservoir cap (if equipped).
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 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.
■ Notice on coolant quality
Do not use improper coolant. If improper coolant is used, the engine cooling
system may be damaged.

■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 smart entry &
start system)
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P (automat ic transmission) or depress the brake
pedal with the shift lever in N (manual transmission).
Open and close any of the doors.
Restart the engine.
● 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 system will not start even after multiple attempts, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ If a symbol of a battery is shown on the multi-information display (if
equipped)
There is a malfunction in the vehicle’s charging system.
Immediately stop the vehicle in a safe place and contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer. Continu-
ing to drive the vehicle may be dangerous.

sion.
Washer fluid
WARNING
■ When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid
contains alcohol and may catch fi re if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces as well as
damaging the pump leading to problems of the washer fluid not spraying.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures list ed on the label of the washer fluid bot-

Maintenance and care
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. Even if
you decide to drain it yourself, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 637)
Vehicles with multi-information display
When “WATER ACCUMULATION IN FUEL FILTER SEE
OWNER’S MANUAL”/“Water accumulation in fuel filter See owner’s
manual” is shown on the multi-information display and a buzzer
sounds*1.
Vehicles without smart entry & start system: Turn the engine switch
to the “LOCK” position.
Vehicles with smart entry & start system: Turn the engine switch off.
For EURO VI models*3:
Remove the fuel filter from the
bracket as shown in the illustra-

Maintenance and care
AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. AdBlue™ is consumed in the process of driving. Therefore,
observe the following precautions.
● Vehicles without water-cooled intercooler:
1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed every 1500 km
(932 miles). Normally, after a full refill, the vehicle can be driven for
approximately 15000 km (9321 miles) before all AdBlue™ is
depleted. However, AdBlue™ may become completely depleted
sooner depending on driving conditions.
● Vehicles with water-cooled intercooler:
1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed every 600 km
(373 miles). Normally, after a full refill, the vehicle can be driven for
approximately 8000 km (4971 miles) before all AdBlue™ is
depleted. However, AdBlue™ may become completely depleted
sooner depending on driving conditions.
● When the possible driving range based on the remaining amount of
AdBlue™ reaches approximately 2400 km (1492 miles), the low
AdBlue™ level warning light turns on and a warning message is
displayed.
● When AdBlue™ is depleted, the engine cannot be restarted.
● If AdBlue™ is accidentally spilled while refilling, vehicle parts, paint,
etc. may be damaged.
When AdBlue™ needs to be refilled, have it refilled at any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
It may be a criminal offence to use a vehicle that does not consume
any reagent if it is required for the reduction of emissions.
■AdBlue™ warning light and warning message
When the AdBlue™ level is low,
the low AdBlue™ level warning
light turns on and a warning
message appears on the multi-
information display. ( P. 586)
When refilling AdBlue™ by
yourself in an emergency, be
sure to follow the correct refill-
ing procedures. ( P. 587)

● Use AdBlue™ (compliant with ISO 22241-1).
AdBlue™ is a trademark of the German Association of the Automotive
Industry (VDA).
● Before driving for a long period of time in an area where AdBlue™ cannot
be refilled, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
