Maintenance and care
■
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:
1.2 qt. (1.1 L, 1.0 lmp. qt.)
■ Recommended viscosity
5W-20 or 0W-20
SAE 5W-20 or 0W-20 motor oil
may be used. However, SAE 0W-
20 is the best choice for fuel
economy and good starting in
cold weather.

■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacing. ( →P. 336)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
