perature and turned off, check the  
oil level on the dipstick.
■Checking the engine oil 
1 Park the vehicle on level  
ground. After warming up the  
engine and turning off the hybrid  
system, wait more than 5 min- 
utes for the oil to drain back into  
the bottom of the engine. 
2 Holding a rag under the end,  
pull the dipstick out. 
3 Wipe the dipstick clean. 
4 Reinsert the dipstick fully. 
5 Holding a rag under the end,  
pull the dipstick out and check  
the oil level. 
Low 
Normal
Excessive
The shape of the dipstick may differ  
depending on the type of vehicle or  engine.
6 Wipe the dipstick and reinsert it  
fully.
■Checking the oil type and pre-
paring the item needed 
Make sure to check the oil type and  
prepare the items needed before  
adding oil.

■Adding engine oil 
If the oil level is below or near the  
low level mark, add engine oil of the  
same type as that already in the  
engine. 
1 Remove the oil filler cap by turn- 
ing it counterclockwise. 
2 Add engine oil slowly, checking  
the dipstick. 
3 Install the oil filler cap by turning  
it clockwise.

Maintenance and care
■Engine oil consumption 
A certain amount of engine oil will be  
consumed while driving. In the following  situations, oil consumption may increase, and engine oil may need to be  
refilled in between oil maintenance inter- vals.
●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 inappropri-ate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing  
(vehicles with towing packages), 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 
The engine oil maintenance data should  be reset. Perform the following proce- 
dures: 
1 Press   /   (7-inch display) or  
 /   (4.2-inch display) of the  
meter control switch to select  . 
2 Press   /   (7-inch display) or  
 /   (4.2-inch display) to select  
“Vehicle Settings” and then press  
and hold  . 
3 Press   /   to select “Oil Mainte- 
nance” and then press  . 
4 Press   /   to select “Yes” and  
then press  . 
A message will be displayed on the  multi-information display when the reset  
procedure has been completed.
■Engine coolant reservoir 
The coolant level is satisfactory if it  
is between the “F” and “L” lines on  
WARNING 
■Used engine oil
●Used engine oil contains poten- 
tially harmful contaminants which  may cause skin disorders such as inflammation and skin cancer, so  
care should be taken to avoid pro- longed 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 fil- 
ters in household trash, in sewers  or onto the ground.Call any authorized Toyota retailer  
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 dam- age 
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.

and turn off the hybrid system, wait 
more than 5 minutes, and check the 
oil level on the dipstick.

Gasoline Engine   
“Toyota Genuine Motor Oil” is used  
in your Toyota vehicle. Toyota rec- 
ommends the use of approved  
“Toyota Genuine Motor Oil”.  
Another motor oil of matching qual- 
ity can also be used. 
Oil grade: 
0W-8: JASO GLV-1 
0W-16: 
API grade SN “Resource-Conserv- 
ing”, SN PLUS “Resource-Conserv- 
ing” or SP “Resource-Conserving”;  
or ILSAC GF-6B multigrade engine

0W-20 and 5W-30:

ILSAC GF-6A multigrade engine oil 
Recommended viscosity (SAE):

Temperature range anticipated  
before next oil change 
SAE 0W-8 is filled into your Toyota  
vehicle at manufacturing, and the  
best choice for good fuel economy  
and good starting in cold weather. If  
SAE 0W-8 oil is not available, SAE  
0W-16 or 0W-20 oil may be used.  
However, it should be replaced with  
SAE 0W-8 at the next oil change. 
Oil viscosity (0W-8 is explained  
here as an example): 
• The 0W in 0W-8 indicates the  
characteristic of the oil which  
allows cold startability. Oils with a  
lower value before the W allow  
for easier starting of the engine  
in cold weather. 
• The 8 in 0W-8 indicates the vis- 
cosity characteristic of the oil  
when the oil is at high tempera- 
ture. An oil with a higher viscos- 
ity (one with a higher value) may  
be better suited if the vehicle is
