NOTICE
To prevent serious engine damage
Check the oil level on 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.
Engine oil
1AD-FTV engines using diesel fuel that contains 500 ppm or less of sul-
phur (P. 120)
Do not use ACEA C2 as it will degrade the oil when used.
1AD-FTV (with DPF catalytic converter)
* and 2AD-FHV engines
(P. 120)
Using engine oil other than ACEA C2 may damage the catalytic con-
verter.
1WW-FHV engine (P. 120)
Using engine oil other than “Toyota Genuine Motor Oil 5W-30 Premium
Fuel Economy for 1WW/2WW engines” may damage the catalytic con-
verter.
If “Toyota Genuine Motor Oil 5W-30 Premium Fuel Economy for 1WW/
2WW engines” or any of the approved engine oils listed are not available
at the time, up to 1 L of ACEA C3 can be used to refill.
*: To distinguish the 1AD-FTV engine, ask any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

Maintenance and care
Fuel filter (diesel engine only)
The water in the fuel filter needs to be drained in either of the follow-
ing situations:
• The “DRAIN WATER FROM FUEL FILTER” warning message is
shown on the multi-information display and a buzzer sounds.
(P. 525)
• 1WW-FHV engine only: Every 20000 km (12000 miles) or 12
months.
1AD-FTV and 2AD-FHV engines
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.
Vehicles without smart entry & start system:
Turn the engine switch to the “LOCK” position.
Vehicles with smart entry & start system:
Turn the “ENGINE START STOP” switch off.
Place a small tray under the drain plug to catch the water and
any fuel that comes out.
Turn the drain plug counterclock-
wise 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.
1WW-FHV engine
Have the fuel filter drained by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

Maintenance and care
Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced. Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 621)
