Checking Oil Level; Adding Washer Fluid; Maintenance-Free Battery - Jeep Cherokee 2018 Owner's Manual

Checking Oil Level

To assure 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 three 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.
NOTE:
Always maintain the oil level within the cross-
hatch markings on the dipstick.
Adding 1 quart (1.0 liters) 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.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.

Adding Washer Fluid

The windshield and rear window washers share
the same fluid reservoir. The fluid reservoir is
located in the front of the engine compartment.
Be sure to check the fluid level in the reservoir at
regular intervals. Fill the reservoir with wind-
shield washer solvent (not radiator antifreeze)
and operate the system for a few seconds to
flush out the residual water.
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.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised when
filling or working around the washer solution.

Maintenance-Free Battery

Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to "Jump
Starting Procedure" in "In Case Of Emer-
gency" for further information.
• Battery gas is flammable and explosive.
Keep flame or sparks away from the bat-
tery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
• Battery posts, terminals, and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
