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 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.

It is possible for your oil level to be slightly higher than a previous check. This would be due to diesel fuel that may temporarily be in the crankcase due to operation of the diesel partic- ulate filter regeneration strategy (if equipped). This fuel will evaporate out under normal oper- ation.

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.

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, aids cleaning action, reduces the freezing point to avoid line clogging, and is not harmful to paint or trim.

MAINTENANCE-FREE BATTERY

Your vehicle is equipped with a

maintenance-free battery. You will never have to add water, and periodic maintenance is not required.

PRESSURE WASHING

Cleaning the engine compartment with a high pressure washer is not recommended.
