ENGINE
196Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. The approximate quantity of oil
needed to fill between the low line and the full line on the
dipstick is indicated below for reference.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
Oil quantity. L (qt., Imp. qt.) 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstick once again after
adding the oil.
Engine oil selection
Use API SH, Energy±Conserving II multigrade engine oil or
ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W±30 is the best choice for your vehicle, for good
fuel economy, and good starting in cold weather.
If you use SAE 10W±30 engine oil in extremely low
temperatures, the engine may become difficult to start,
so SAE 5W±30 engine oil is recommended.

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.)
