54GETTING TO KNOW YOUR VEHICLE
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the
windshield and automatically activates the wipers.
Rotate the end of the multifunction lever to one of
five detent positions to activate this feature.
The sensitivity of the system can be adjusted with
the multifunction lever. Wiper delay position 1 is
the least sensitive, and wiper delay position 5 is
the most sensitive. Position 3 should be used for
normal rain conditions. Positions 1 and 2 can be
used if the driver desires less wiper sensitivity.
Positions 4 and 5 can be used if the driver desires
more sensitivity. Place the wiper switch in the
O (off) position when not using the system.
NOTE:
The Rain Sensing feature will not operate when
the wiper switch is in the low or high-speed posi -
tion.
The Rain Sensing feature may not function prop -
erly when ice, or dried salt water is present on
the windshield.
Use of Rain-X or products containing wax or sili-
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off using the Uconnect system Ú page 191.The Rain Sensing system has protection features
for the wiper blades and arms, and will not operate
under the following conditions:
Low Ambient Temperature
— When the ignition
is first placed in the ON position, the Rain
Sensing system will not operate until the wiper
switch is moved, vehicle speed is greater than
0 mph (0 km/h), or the outside temperature is
greater than 32°F (0°C).
Transmission In NEUTRAL Position — When the
ignition is ON, and the transmission is in the
NEUTRAL position, the Rain Sensing system will
not operate until the wiper switch is moved,
vehicle speed is greater than 5 mph (8 km/h),
or the gear selector is moved out of the
NEUTRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with the Remote Start system, Rain
Sensing wipers are not operational when the
vehicle is in the Remote Start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the RUN position, Rain Sensing
wiper operation can resume, if it has been
selected, and no other inhibit conditions
(mentioned previously) exist.
CLIMATE CONTROLS
The Climate Control system allows you to regulate
the temperature, air flow, and direction of air
circulating throughout the vehicle. The controls are
located on the touchscreen (if equipped), on the
sides of the touchscreen, or on the instrument
panel below the radio.

340SERVICING AND MAINTENANCE
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.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1 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 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.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's
charging system.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.
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.
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 Úpage 320.
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 accesso -
ries contain lead and lead compounds. Wash
hands after handling.

SERVICING AND MAINTENANCE351
the EPA Heavy Duty Diesel Engine Emissions
Standards. These systems are seamlessly
integrated into your vehicle and managed by the
Cummins® Powertrain Control Module (PCM). The
PCM manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or
interaction on your part.
If the engine is allowed to idle or the truck is driven
on low engine speed drive cycles for more than two
hours, the system will automatically enter an
emissions operating mode that will increase the
engine idle speed to 1,050 RPM. While in this
mode, which is designed to help maintain the
Diesel Particulate Filter, the engine idle speed will
return to normal when the brake pedal is applied.
A small change in engine tone or a slight change in
engine performance while accelerating may also
be noticeable at speeds below 20 mph (32 km/h).
This operating mode may last for up to an hour of
idle time, or around 20 minutes of driving time.
Additionally, your vehicle has the ability to alert you
to additional maintenance required on your truck
or engine Ú page 81.
DIESEL EXHAUST FLUID (DEF)
DEF sometimes known simply by the name of its
active component, UREA—is a key component of
Selective Catalytic Reduction (SCR) systems, which
help diesel vehicles meet stringent emission
regulations. DEF is a liquid reducing agent that
reacts with engine exhaust in the presence of a
catalyst to convert smog-forming nitrogen oxides
(NOx) into harmless nitrogen and water vapor
Úpage 404.
You can receive assistance in locating DEF by
contacting 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 ensure quiet, easy operation and to protect against rust and wear. Prior to the
application 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
services, 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 Autumn 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.
WARNING!
A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact
with your exhaust system. Do not park or oper
-
ate your vehicle in areas where your exhaust sys -
tem can contact anything that can burn.

352SERVICING AND MAINTENANCE
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor
performance of blades may be present with chat -
tering, marks, water lines or wet spots. If any of
these conditions are present, clean the wiper
blades or replace as necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following points:
Wear or uneven edges
Foreign material
Hardening or cracking
Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace
the affected wiper arm or blade with a new unit. Do
not attempt to repair a wiper arm or blade that is
damaged.
Wiper Blade Removal/Installation

1. Lift the wiper arm to raise the wiper blade off of the glass, until the wiper arm is in the full
