IN CASE OF EMERGENCY297
SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in
Mexico may not answer or respond to SOS
system calls.
If the SOS Call system detects a malfunction,
any of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console light located between
the ASSIST and SOS buttons will continuously
be illuminated red.
The Device Screen will display the following
message: “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state
“Vehicle device requires service. Please
contact an authorized dealer.” Even if the SOS Call system is fully functional,
factors beyond FCA US LLC’s control may
prevent or stop the SOS Call system operation.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter
-
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
system or modify the antennas on your
vehicle. IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to
fail when you need it. You could be injured
if the air bag system is not there to help
protect you.
WARNING! (Continued)WARNING!
Ignoring the overhead console light could
mean you will not have SOS Call services. If
the overhead console light is illuminated,
have an authorized dealer service the SOS
Call system immediately.
The Occupant Restraint Control module
turns on the air bag Warning Light on the
instrument panel if a malfunction in any
part of the system is detected. If the Air Bag
Warning Light is illuminated, have an
authorized dealer service the Occupant
Restraint Control system immediately.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GAS ENGINE
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indi-
cator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Severe Operating Condi-
tions can cause the change oil message to illu -
minate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles
(805 km). An authorized dealer will reset the oil change
indicator message after completing the sched
-
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
Gas Engines:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or very low
engine RPM. This type of vehicle use is consid -
ered Severe Duty. Once A Month Or Before A Long Trip:Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look
for unusual wear or damage. Rotate at the
first sign of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only), and
fill as needed.
Check function of all interior and exterior
lights.

Oil Change Indicator System — Cummins
Diesel
Your vehicle is equipped with an engine oil
change indicator system. This system will alert
you when it is time to change your engine oil by
displaying the words “Oil Change Due” in your
instrument cluster display. The oil change
reminder will remind the owner to change the
engine oil every 15,000 miles (24,000 km) or
500 hours, whichever comes first, except for
the Chassis Cab models configured with
optional B20 capability that are using greater
than 5% levels of biodiesel, which are
12,500 miles (20,000 km) or 400 hours,
whichever comes first. Failure to change the
engine oil per the maintenance schedule can
result in internal engine damage.
An authorized dealer will reset the oil change
indicator message after completing the sched -
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information. Replace the engine oil and oil filter every 15,
000 miles (24,000 km) or 12 months, or
sooner if prompted by the oil change indicator
system. Under no circumstances should oil
change intervals exceed 15,000 miles (24,
000 km) or 12 months, whichever comes first.
NOTE:
Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km)
or 12 months or 500 Hours, whichever
comes first.
Replace the engine oil and oil filter every
12,500 miles (20,000 km) or 400 hours,
whichever comes first when running greater
than 5% levels of biodiesel (Chassis Cab
models configured with optional B20 capa
-
bility).
If Chassis Cab models configured with optional
B20 capability are operated with greater than
5% levels of biodiesel, the oil change interval
must not exceed 12,500 miles (20,000 km) or
400 hours, whichever comes first under any
circumstances. See the Fuel Requirements
section for more information regarding opera -
tion with biodiesel blend (B6-B20) fuel meeting
ASTM specification D-7467.
Perform Service Indicator — Cummins
Diesel
Your vehicle will require emissions mainte -
nance at a set interval. To help remind you
when this maintenance is due, the instrument
cluster will display “Perform Service”. When the
“Perform Service” message is displayed on the
instrument cluster it is necessary to have the
emissions maintenance performed. Emissions
maintenance may include replacing the Closed
Crankcase Ventilation (CCV) filter element. The
procedure for clearing and resetting the
“Perform Service” indicator message is located
in the appropriate Service Information.

Intervention Regeneration Strategy —
Message Process Flow
The Cummins diesel engine meets all Environ -
mental Protection Agency (EPA) Heavy Duty
Diesel Engine Emissions Standards, resulting in
one of the lowest emitting diesel engines ever
produced.
To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art
engine and exhaust system. The engine and
exhaust after-treatment system work together
to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seam -
lessly 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 automati -
cally enter an emissions operating mode that
will increase the engine idle speed to 900 RPM
(1,050 RPM for Chassis Cab). 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 kmh). 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.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (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.
Refer to “Fluids And Lubricants” in “Technical
Specification” for further information.
You can receive assistance in locating DEF in
the United States by calling 866-RAM-INFO
(866-726-4636). In Canada call
1–800–465–2001 (English) or
1–800–387–9983 (French)
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 operate your vehicle in areas where
your exhaust system can contact anything
that can burn.7

368SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission perfor-
mance and life. Use only the manufacturer’s
specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It
is important to maintain the transmission fluid
at the correct level using the recommended
fluid. No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
Special Additives
The manufacturer strongly recommends
against using any special additives in the trans -
mission. Automatic Transmission Fluid (ATF) is
an engineered product and its performance
may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the
transmission. The only exception to this policy is
the use of special dyes for diagnosing fluid
leaks in six-speed transmissions. Avoid using
transmission sealers as they may adversely
affect seals.
Fluid Level Check — Eight-Speed
Transmission
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required, therefore the transmission has no dipstick. An authorized dealer can check your
transmission fluid level using special service
tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immedi
-
ately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe transmis -
sion damage.
Fluid Level Check — Six-Speed Transmission
It is best to check the fluid level when the trans -
mission is at normal operating temperature
(158-176°F / 70-80°C). This normally occurs
after at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot
be held comfortably between the fingertips. You
can read the transmission sump temperature in
the instrument cluster screen (refer to “Instru -
ment Cluster Display” in “Getting To Know Your
Instrument Panel” for further information).
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder, and
(for six-speed transmissions) will require
more frequent fluid and filter changes. Refer
to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

SERVICING AND MAINTENANCE369
Use the following procedure to check the trans -
mission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and
operate the vehicle as required to reach
the normal operating temperature. If the
transmission is not functioning properly, or
the vehicle cannot be driven, see the NOTE
and CAUTION below about checking the
fluid level at colder temperatures.

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each posi -
tion), ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and rein -
sert it until seated. 7. Remove the dipstick again and note the
fluid level on both sides. The fluid level
reading is only valid if there is a solid
coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full
of fluid if the actual level is at or above the
hole. The fluid level should be between the
“HOT” (upper) reference holes on the
dipstick at normal operating temperature. If
the fluid level is low, add fluid through the
dipstick tube to bring it to the proper level.
Do not overfill. Use ONLY the specified fluid
(refer to "Fluids And Lubricants" in “Tech -
nical Specifications” for fluid specifica -
tions). After adding any quantity of oil
through the dipstick tube, wait a minimum
of two minutes for the oil to fully drain into
the transmission before rechecking the
fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two “COLD” (lower)
holes on the dipstick with the fluid at 60-70°F /
16-21°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
8. Reinsert the dipstick. Check for leaks.
Release the parking brake.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two COLD (lower) holes
on the dipstick with the fluid at 68-86°F /
20-30°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
CAUTION!
If the fluid temperature is below 50 °F (10
°C) it may not register on the dipstick. Do not
add fluid until the temperature is elevated
enough to produce an accurate reading. Run
the engine at idle, in PARK, to warm the fluid.

After a tire rotation is completed, as shown
below, the system can auto learn the loca -
tions of each sensor ID. Auto learning/local -
ization occurs when the vehicle ignition
status is changed from Off to On and speeds
of greater than 5 mph (8 km/h) are obtained and remain over 5 mph (8 km/h) for at about
a 15 minute period. You may need to drive
for 20 minutes to account slower speeds and

DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in addi -
tion to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to varia -
tions in driving habits, service practices,
and differences in road characteristics
and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
CAUTION!
4500/5500 Dual Rear Tires may only have
one approved direction of rotation. This is
to accommodate the asymmetrical design
(tread pattern) of the On/Off road tire.
When replacing a flat, the spare tire may
have to be remounted on the rim or
installed at a different location to maintain
the correct placement of the tire on the
wheel relative to the tire/wheel position on
the vehicle. For example, if the spare is
used to replace an outer rear tire it will have
to be remounted on the rim so that the
wheel is dished inward. That way the tread
design of asymmetrical tires will maintain
proper position.
CAUTION! (Continued)
