Checking Oil Level; Adding Washer Fluid; Maintenance-Free Battery - Dodge RAM 1500 2020 Owner's Manual

HECKING IL EVEL
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.
NOTE:
Always maintain the oil level within the crosshatch
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.
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
NOTE:
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 particulate filter regeneration strategy (if equipped).
This fuel will evaporate out under normal operation.

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.
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.
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.

AINTENANCE REE ATTERY
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" in "In
Case Of Emergency" for further information.
 Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. 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 accessories
contain lead and lead compounds. Wash hands after
handling.
CAUTION!
 It is essential when replacing the cables on the
battery that the positive cable is attached to the posi-
tive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
