Park the vehicle on level ground. After turning off the engine, wait
a few minutes for the oil to drain back into the bottom of the
engine.
Hold a rag under the end and pull
the dipstick out.

■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 may be used. However, it
should be replaced with SAE 5W-
30 at the next oil change.
■How to read oil container labels
Some oil containers are labeled with ILSAC certification marks that
help you to select the proper oil.
Temperature range anticipated before
next oil change.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
●The 5W portion of the oil viscosity rating 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 30 in 5W-30 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.
