INSPECTION

CHECK ENGINE OIL QUALITY

Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.

Oil grade:
API grade SH, Energy–Conserving II or SJ, Energy–
Conserving or ILSAC multigrade engine oil.
SAE 5W–30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.

CHECK ENGINE OIL LEVEL

After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the ”L” and ”F” of the dipstick.
If low, check for leakage and add oil up to the ”F” mark.
NOTICE:

Do not fill with engine oil above the ”F” mark.

Install the oil dipstick facing the direction shown in
the illustration.

REPLACEMENT

CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Exercise caution in order to minimize the length and
frequency of contact of your skin to used oil. Wear
protective clothing and gloves. Wash your skin thor-
oughly with soap and water, or use water–less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filter must be disposed of only at designated
disposal sites.

DRAIN ENGINE OIL

(a)

Remove the oil filler cap.

(b)

Remove the oil drain plug, and drain the oil into a contain-
er.
