■Adding the 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.
Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Return the filler cap and turn the ca
p clockwise until you hear a
click.
It takes about 1.6 qt. (1.5 L, 1.3 lmp.qt.) to raise the oil level from low to full on the
dipstick.
■ Recommended viscosity
Temperature range anticipated before next oil change.
SAE 5W-30 is the best choice for
goo
d fuel economy, and good starting
in cold weather.
If SAE 5W-30 is not available, SAE
1
0W-30 may be used. However, it

■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 fre -
quent acceleration and deceleration.
●A new engine consumes more oil, since its pistons, piston rings and cylinder
walls have not become conditioned.
●Oil consumption: Max. 1. 1 qt./600 miles (1.0 L per 1000 km, 0.9 lmp.qt/600
miles).
●If you consume more than 1.1 quarts (1.0 L, 0.91 lmp.qt.) every 300 miles
(500km), see your dealer.
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammati on or skin cancer, so care should be taken to avoid
prolonged and repeated contact with it. 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 dis -
pose of used oil and filters in household trash, in sewers or onto the ground. Call
