ENGINE BREAK-IN
RECOMMENDATIONS — GASOLINE
ENGINE
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided. The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem. Please check your oil level with
the engine oil indicator often during the
break in period. Add oil as required.
ENGINE BREAK-IN
RECOMMENDATIONS — 6.7L DIESEL
The Cummins turbocharged diesel engine
does not require a break-in period due to its
construction. Normal operation is allowed,
providing the following recommendations are
followed:
127
• Warm up the engine before placing it underload.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time.
For additional vehicle break-in requirements,
refer to “Trailer Towing” in “Starting And Oper-
ating” of the Owner’s Manual at
www.mopar.com/en-us/care/
owners-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents). Because of the construction of the Cummins
turbocharged diesel engine, engine run-in is
enhanced by loaded operating conditions
which allow the engine parts to achieve final
finish and fit during the first 6,000 miles
(10 000 km).
AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
WARNING!
parking brake, shift the transmission
into PARK, turn the engine OFF, and
remove the key fob. When the ignition is
in the LOCK/OFF (key removal) position,
(or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the trans-
mission is locked in PARK, securing the
vehicle against unwanted movement.
• When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never use the PARK position as a sub-
stitute for the parking brake. Always
apply the parking brake fully when exit-
ing the vehicle to guard against vehicle
movement and possible injury or dam-
age.
• Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
STARTING AND OPERATING
128
WARNING!
• Never leave children alone in a vehicle,or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
•
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave the ignition (in a
vehicle equipped with Keyless Enter-N-
Go) in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
• Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
CAUTION!
• Do not shift between PARK, REVERSE,NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position. NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition to warn you that
this safety feature is inoperable. The engine
can be started and stopped but the key fob
cannot be removed until you obtain service.
Brake/Transmission Shift
Interlock System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
Six–Speed Automatic
Transmission — If Equipped
Chassis Cab models (with automatic trans-
mission) may use either the AS66RC or
AS69RC transmission (which are equipped
with a Power Take-Off (PTO) access cover on
the side of the transmission case), or the
66RFE transmission (which has no PTO ac-
cess cover).
129
The transmission gear position display (lo-
cated in the instrument cluster) indicates the
transmission gear range. The gear selector is
mounted on the right side of the steering
column. You must press the brake pedal to
move the gear selector out of PARK (refer to
“Brake/Transmission Shift Interlock System”
in this section). To drive, move the gear
selector from PARK or NEUTRAL to the
DRIVE position. Pull the gear selector toward
you when shifting into REVERSE or PARK, or
when shifting out of PARK.
The electronically-controlled transmission
provides a precise shift schedule. The trans-
mission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal
condition, and precision shifts will develop
within a few hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting be-
tween these gears.The transmission gear selector has only
PARK, REVERSE, NEUTRAL, and DRIVE
shift positions. Manual downshifts can be
made using the Electronic Range Select
(ERS) shift control. Pushing the ERS (-/+)
switches (on the gear selector) while in the
DRIVE position will select the highest avail-
able transmission gear, and will display that
gear limit in the instrument cluster as 1, 2, 3,
etc. Refer to "Electronic Range Select (ERS)
Operation" in this section for further informa-
tion. Some models will display both the se-
lected gear limit, and the actual current gear,
while in ERS mode.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains
in fourth gear (for 66RFE transmission) or third
gear (for AS66RC/AS69RC transmission) re-
gardless of which forward gear is selected. If an
AS66RC/AS69RC equipped truck enters Limp
Home Mode at highway speeds, it will initially
engage fifth gear, until the vehicle slows to a speed where third gear can be engaged. PARK,
REVERSE, and NEUTRAL will continue to op-
erate. The Malfunction Indicator Light (MIL)
may be illuminated. Limp Home Mode allows
the vehicle to be driven to an authorized dealer
for service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all for-
ward gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip-
ment to assess the condition of your trans-
mission.
STARTING AND OPERATING
130
If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift con-
trol allows the driver to limit the highest
available gear when the transmission is in
DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the trans-
mission will not shift above fourth gear, but
will shift through the lower gears normally.
You can switch between DRIVE and ERS
mode at any vehicle speed. When the gear
selector is in the DRIVE position, the trans-
mission will operate automatically, shifting
between all available gears. Tapping the ERS
(-) switch will activate ERS mode, display the
current gear in the instrument cluster, and
set that gear as the top available gear. Once
in ERS mode, tapping (-) or (+) will change
the top available gear.To exit ERS mode, simply push and hold the
ERS (+) switch until the gear limit display
disappears from the instrument cluster.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
push and hold the ERS (-) switch. The trans-
mission will shift to the range from which the
vehicle can best be slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.
FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
• Four-wheel drive trucks are equipped with either a manually shifted transfer case or an
electronically shifted transfer case. Refer to
the operating instructions for electronic
transfer case, located in this section for
further information.
• For further information on the manually shifted transfer case, refer to “Four Wheel
Drive Operation” in “Starting And Operat-
ing” in your Owner’s Manual located at

will be established.To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains speed
up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain
may occur so it may be preferable to drive
without Speed Control.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the
RES (+) button and release. Resume can be
used at any speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the
CANCEL button, or normal brake pressure
while slowing the vehicle will deactivate the
Speed Control without erasing the set speed
from memory.
Pushing the ON/OFF button or turning the
ignition switch OFF erases the set speed from

for further information.WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView should only be used as a parking aid.
The ParkView camera is unable to view
every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle
must be driven slowly when using
ParkView to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/
her shoulder when using ParkView.
137
CAUTION!
• Then, during the first 500 miles(805 km) that a trailer is towed, do not
drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps
the engine and other parts of the vehicle
wear in at the heavier loads.
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance”
for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision.
Follow these guidelines to make your
trailer towing as safe as possible:
• Make certain that the load is secured in the trailer and will not shift during travel.
When trailering cargo that is not fully
secured, dynamic load shifts can occur
that may be difficult for the driver to
WARNING!
control. You could lose control of your
vehicle and have a collision.
• When hauling cargo or towing a trailer,
do not overload your vehicle or trailer.
Overloading can cause a loss of control,
poor performance or damage to brakes,
axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always
connect the chains to the hook retainers
of the vehicle hitch. Cross the chains
under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be
parked on a grade. When parking, apply
the parking brake on the tow vehicle. Put
the tow vehicle transmission in PARK.
For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL.
Always, block or "chock" the trailer
wheels.
• GCWR must not be exceeded.
WARNING!
• Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Trailer Brakes
•Do notinterconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause
inadequate braking and possible personal
injury.
• An electronically actuated trailer brake controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
