2018 Ram 4500 Chassis Cab wiper fluid

The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.
If the washer knob is depressed while in the delay range,
the wiper will operate for several seconds after the washer
knob is released. It will then resume the intermittent
interval previously selected. If the washer knob is pushed
while in the off position, the wiper will turn on and cycle
approximately three times after the wash knob is released.
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!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the wind-
shield during freezing weather, warm the windshield
with the defroster before and during windshield
washer use.
Mist Feature
When a single wipe to clear off road mist or spray from a
passing vehicle is needed, push the washer knob, located
on the end of the multifunction lever, inward to the first
detent and release. The wipers will cycle one time and
automatically shut off.
NOTE:The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on the
windshield. The wash function must be used in order to
spray the windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and auto-
matically activates the wipers for the driver. The feature is
especially useful for road splash or overspray from the

Checking Oil Level — Gas Engine
To assure proper lubrication of your vehicle’s engine, 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. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
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 anti-
freeze). 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 con-
tainer, 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, nor is periodic mainte-
nance required.

SERVICING AND MAINTENANCE 365

•Noise (objectionable squeal, squeak, or rumble is heard
or felt while drive belt is in operation)
Some conditions can be caused by a faulty component such
as a belt pulley. Belt pulleys should be carefully inspected
for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle serviced
at an authorized dealer.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such as
Mopar Spray White Lube to assure quiet, easy operation
and to protect against rust and wear. Prior to the applica-
tion of any lubricant, the parts concerned should be wiped
clean to remove dust and grit; after lubricating excess oil
and grease should be removed. Particular attention should
also be given to hood latching components to ensure
proper function. When performing other underhood ser-
vices, the hood latch, release mechanism and safety catch
should be cleaned and lubricated. The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods may
cause deterioration of the wiper blades. Always use washer
fluid when using the wipers to remove salt or dirt from a
dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary.
