ENGINE NOTICE D Be careful not to spill engine oil on the vehicle components. D Avoid overfilling, or the engine could be damaged. D Check the oil level on the dipstick once again after adding the oil. If the oil level is below or only slightly above the low line, add engine oil of the same type as already in the engine. Remove the oil filler cap and add engine oil a little at a time, checking the dipstick. We recommend that you use a funnel when adding oil. The approximate quantity of oil needed to raise the level between low line and full line on the dipstick is indicated as follows: 1.5 L (1.6 qt., 1.3 Imp. qt.) For the engine oil capacity, see "Specifications" on page 518. When the level reaches within the correct range, return the filler cap and turn the cap clockwise until you hear a click. 512
