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 aeration or loss of oil pressure. This could damage your engine.

every fuel stop. The best time to check the

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 (1.0 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 instrument cluster display will indicate when the washer fluid level is low. When the sensor detects a low fluid level, the windshield will light on the vehicle graphic outline and the “WASHER FLUID LOW” message will be displayed.

The fluid reservoir for the windshield washers and the rear window washer is shared. The fluid reservoir is located in the engine compartment; be sure to check the 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 clean the wiper blades, 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.
