WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Additional Maintenance — B6 To
B20 Biodiesel (1500 Diesel)
NOTE:
• Under no circumstances should oil change
intervals exceed 8,000 miles (12,875 km)
or six months, whichever comes first when
using biodiesel blends greater than 5%
(B5).
• The owner is required to monitor mileage for B6-B20 biodiesel, the automatic oil
change indicator system does not reflect
the use of biofuels.
• Fuel filter change interval is maintained at every second oil change. This is especially
important with biodiesel usage.
SCHEDULED MAINTENANCE — 6.7L
CUMMINS DIESEL ENGINE
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.

To determine the maximum loading condi-
tions of your vehicle, locate the statement
“The combined weight of occupants and
cargo should never exceed XXX kg or XXX lbs”
on the Tire and Loading Information placard.
The combined weight of occupants, cargo/
luggage and trailer tongue weight (if appli-
cable) should never exceed the weight refer-
enced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX kg
or XXX lbs.(4) The resulting figure equals the
available amount of cargo and luggage
load capacity. For example, if “XXX”
amount equals 1400 lbs. and there
will be five 150 lb passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5x150) = 650 lbs.)
(5)Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely ex-
ceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg
and there will be five 68 kg passengers in
your vehicle, the amount of available cargo
and luggage load capacity is 295 kg (635-
340 (5x68) = 295 kg) as shown in step 4.
NOTE:
• If your vehicle will be towing a trailer, load from your trailer will be transferred to your
vehicle. The following table shows ex-
amples on how to calculate total load,
cargo/luggage, and towing capacities of
your vehicle with varying seating configura-
tions and number and size of occupants.
This table is for illustration purposes only
and may not be accurate for the seating and
load carry capacity of your vehicle.

Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of your tire (sidewall damage is not repair-
able).
• The puncture is no greater thana¼ofan inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat
tire of identical size and service description
(Load Index and Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi
(96 kPa). Once a Run Flat tire reaches the
run flat mode it has limited driving capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer while
a tire is in the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30 sec-
onds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.

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.

ASSIST Call (4C NAV) —
The rearview mirror
contains an ASSIST button, allowing you to
speak to a call center agent for support:
• Roadside Assistance Call — If you get a
flat tire, or need a tow, you’ll be con-
nected to someone who can help any-
time. Additional fees may apply. Addi-
tional information in this section.
