CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions.
When working on the engine compartment
Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Flat dipstick: Reinsert the dipstick fully.
Non-flat dipstick: Reinsert the
non-flat dipstick fully with its pro-
truding areas (  in the illustra-
tion) pointing towards the
engine.

AVENSIS_OM_OM20B88E_(EE)Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.
The approximate quantity of oil needed to raise the level between low and
full on the dipstick is indicated as follows:
Gasoline engine
1.5 L (1.6 qt., 1.3 Imp.qt.)
1AD-FTV engine
Vehicles with DPF catalytic converter:
1.6 L (1.7 qt., 1.4 Imp.qt.)
Vehicles without DPF catalytic converter:
1.7 L (1.8 qt., 1.5 Imp.qt.)
2AD-FTV and 2AD-FHV engines
1.6 L (1.7 qt., 1.4 Imp.qt.)

Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing 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,
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)
The oil change system should be reset. Perform the following procedures:
Vehicles with smart entry & start system
Switch the display to trip meter A (P. 232) when the engine is run-
ning.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to IGNITION ON mode (but do not start the engine
because otherwise the reset mode will be canceled). Continue to
press and hold the button until the multi-information display indi-
cates that the reset is complete.
Vehicles without smart entry & start system
Switch the display to trip meter A (P. 232) when the engine is run-
ning.
Turn the engine switch to the “LOCK” position.
While pressing the trip meter reset button, set the engine switch to
the “ON” position (but do not start the engine because otherwise
the reset mode will be canceled). Continue to press and hold the
button until the multi-information display indicates that the reset is
complete.
