CHECKING THE ENGINE OIL LEVEL
With the engine at operating temperature and turned
off, check the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level
spot. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go, or
the reading will not be correct.

Add oilO.K.Too full
4. Pull the dipstick out and look at the oil level on the end.
If it is between the full line () and the low line (), it is O.K.
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.

Oil identification marks
API Service SymbolILSAC Certification Mark
Either or both API registered marks are added to some oil
containers to help you select the oil you should use.
The API Service Symbol is located anywhere on the
outside of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SH.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W±30. ªEnergy±Conserving IIº,
shown in the lower portion, indicates that the oil has
fuel±saving capabilities. Oils marked ªEnergy±Conserving
IIº will have higher fuel±saving capabilities than oils
marked ªEnergy±Conservingº.
The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container.
CHECKING THE ENGINE
COOLANT LEVEL

Reservoir capUpper lineLower line
Park the vehicle at a level spot and look at the
see±through coolant reservoir when the engine is cool.
The coolant level is satisfactory if it is between the
upper and lower lines on the tank. If the level is low, add
ethylene±glycol type coolant.
The coolant level in the reservoir will vary with engine coolant
temperature. However, if the level is on or below the lower
line, add coolant to bring the level up to the upper line.
Use only ethylene±glycol type coolant. It will prevent
freezing and corrosion. Neither supplemental inhibitors nor
additives are needed nor recommended. (For information on
ethylene±glycol coolant, see also ªEngine coolant selectionº
described below.)
