CHECKING OIL LEVEL

To ensure proper engine lubrication, the engine oil must be maintained at the correct level.

Check the oil level at regular intervals, such as

Overfilling or underfilling the crankcase will cause oil aeration or loss of oil pressure. This could damage your engine.

After the engine has warmed up, operate the defroster for a few minutes to reduce the possibility of smearing or freezing the fluid on the cold windshield. Windshield washer solution used with water as directed on the container,

engine oil level is about five minutes after a fully warmed up engine is shut off.

Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings.

There are four possible dipstick types:

Crosshatched zone.

Crosshatched zone marked SAFE.

Crosshatched zone marked with MIN at the low end of the range and MAX at the high end of the range.

Crosshatched zone marked with dimples at the MIN and the MAX ends of the range.

Always maintain the oil level within the cross- hatch markings on the dipstick.

Adding 1 quart (1 liter) of oil when the reading is at the low end of the dipstick range will raise the oil level to the high end of the range marking.

ADDING WASHER FLUID

The fluid reservoir is located under the hood and should be checked for fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not radiator antifreeze). When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe the wiper blades clean. This will help blade performance.

To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.
