Maintenance and care
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 fre-
quent 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 accurately.
Oil consumption: Max. 1.0 L/1000 km (1.1 qt./600 miles, 0.9 Imp. qt./600
miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every 1000
km (600 miles), contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
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. 122, 126)
Vehicles without a smart entry & start system:
Turn the engine switch off.
Vehicles with a smart entry & start system:
Turn the engine switch off.
Vehicles without a smart entry & start system:
While pressing the display change button (P. 122, 126), 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 dis-
plays “000000”.
Vehicles with a smart entry & start system:
While pressing the display change button (P. 122, 126), turn the engine
switch to the IGNITION ON mode (do not start the engine because other-
wise the reset mode will be canceled). Continue to press and hold the but-
ton until the trip meter displays “000000”.

CAUTION
Used engine oil
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 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.
When replacing the engine oil
Be careful not to spill engine oil on the vehicle components.
Avoid overfilling, or 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.
Engine oil (diesel engine only)
Using an engine oil other than ACEA C2 may damage the catalytic con-
verter.

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: -35C [-31F])
For more details about engine 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
Except hybrid model: Visually check the radiator, hoses, engine coolant res-
ervoir caps, drain cock and water pump.
Hybrid model: Visually check the radiator, hoses, engine/power control unit
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.

CAUTION
When the engine is hot (except hybrid model)
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.
When the hybrid system is hot (hybrid model)
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

Maintenance and care
Check the radiator, condenser and intercooler and clear away any for-
eign objects.
If any of the above parts are 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.
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.
Radiator, condenser and intercooler
CAUTION
When the engine is hot (except hybrid model)
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.
When the hybrid system is hot (hybrid model)
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

Maintenance and care
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following before recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt 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 12-volt battery. If this happens, use
the wireless 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 12-volt battery is
reconnected, the vehicle will return the engine switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the engine before disconnect the 12-volt battery. Take extra care when con-
necting the 12-volt 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 dealer or repairer, or another duly qualified and equipped professional.

CAUTION
Chemicals in the 12-volt 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
12-volt battery:
Do not cause sparks by touching the 12-volt battery terminals with tools.
Do not smoke or light a match near the 12-volt battery.
Avoid contact with eyes, skin and clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the 12-volt battery.
Keep children away from the 12-volt battery.
Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-
volt battery in a garage or closed room where there is insufficient ventila-
tion.
How to recharge the 12-volt battery
Only perform a slow charge (5 A or less). The 12-volt battery may explode if
charged at a quicker rate.
Emergency measures regarding electrolyte
If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.
If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
