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. 1.0 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. 287)
Vehicles without a smart entry & start system:
Turn the engine switch to the “LOCK” position.
Vehicles with a smart entry & start system:
Turn the “ENGINE START STOP” switch off.
Vehicles without a smart entry & start system:
While pressing the display change button (P. 287), 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. 287), turn the
“ENGINE START STOP” switch to the IGNITION ON mode (do not
start the engine because otherwise the reset mode will be can-
celed). Continue to press and hold the button until the trip meter
displays “000000”.

If luggage is placed on a passenger seat, the passenger detection sensor
may cause the warning light to flash even if a passenger is not sitting in
the seat.
If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
Electric power steering warning light (warning buzzer)
Except hybrid vehicle: When the battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
Hybrid vehicle: When the 12-volt battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
If the malfunction indicator lamp comes on while driving
For some models, the malfunction indicator lamp will come on if the fuel tank
becomes completely empty. If the fuel tank is empty, refuel the vehicle
immediately. The malfunction indicator lamp will go off after several trips.

Toyota dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
If the engine oil change reminder light flashes (diesel engine with a
DPF system)
Repeated short trips and/or low-speed driving may cause the oil to degrade
sooner than usual, regardless of the actual distance driven. If this happens,
the engine oil change reminder light will flash.
Engine oil change reminder light comes on (diesel engine only)
Vehicles without a DPF system:
Replace the engine oil and oil filter when the engine oil change reminder

CAUTION
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
When driving to clean the DPF catalytic converter
