Priming If The Engine Has Run
Out Of Fuel
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure
fuel spray can cause serious injury or
death.
1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to
19L).
2. Turn ignition switch to the start position to engage starter for one second, return ig-
nition switch to run position. This will
activate in tank fuel pump for approxi-
mately 15 seconds. Repeat this process
twice.
3. Start the engine using the “Normal Start- ing” procedure. Refer to “Starting Proce-
dures” in “Starting and Operating” for
further information.
CAUTION!
Do not engage the starter motor for more
than 15 seconds at a time. Allow two
minutes between the cranking intervals.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system. NOTE:
• A maximum blend of 5% biodiesel, meet-
ing ASTM specification D-975 may be used
with your Cummins diesel engine. (Chassis
Cab models not configured with B20 capa-
bility.)
• A maximum blend of 20% biodiesel, meet- ing ASTM specification D-7467 may be
used with your Cummins diesel engine.
(Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20% can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or approved for use with your Cummins diesel
engine.
• In addition, commercially available fuel ad- ditives are not necessary for the proper
operation of your Cummins diesel engine.

Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear edge
of the driver's side door.
At least once a month:
• Check and adjust tire pressure with a goodquality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the valve stem.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall.
Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking tire
pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to your
authorized tire dealer or original equipment
vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation
pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
265

It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your autho-
rized tire dealer or original equipment dealer
with any questions you may have on tire
specifications or capability. Failure to use
equivalent replacement tires may adversely
affect the safety, handling, and ride of your
vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
WARNING!
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi-
fied by the M+S, M&S, M/S or MS designa-
tion on the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.SERVICING AND MAINTENANCE

WARNING!
• ALWAYS obey traffic laws and pay atten-tion to the road. Some features are lim-
ited while the vehicle is in motion. Some
services, including SOS, will NOT work
without a subscription and an operable
network connection.
• Ignoring the rearview mirror light could
mean you may not have SOS Call service
if needed. If the rearview mirror light is
illuminated, have an authorized dealer
service the SOS Call system immedi-
ately.
• The Occupant Restraint Controller
(ORC) turns on the Air Bag Warning
Light on the instrument panel if a mal-
function is detected in any part of the
airbag system. If the Air Bag Warning
Light is illuminated, the air bag system
may not be working properly and the
SOS Call system may not send a signal to
a SOS Call operator if an air bag is
deployed. If the Air Bag Warning Light is
illuminated, have an authorized dealer
service your vehicle immediately.
WARNING!
• If anyone in the vehicle could be indanger (e.g., fire or smoke is visible,
dangerous road conditions or location),
do not wait for voice contact from a SOS
Call operator. All occupants should exit
the vehicle immediately and move to a
safe location.
• 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 sig-
nal to initiate an emergency call. To
avoid interference that can cause the
SOS Call system to fail, never add after-
market 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 (INCLUD-
ING DURING OR AFTER AN ACCI-
DENT), the Uconnect features, apps,
and SiriusXM Guardian services, among
others, will not operate. NOTE:
Your vehicle may be transmitting data as
authorized by the subscriber.
