Oil Life Reset
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change
Required” message will display in the instru-
ment cluster display after a single chime has
sounded, to indicate the next scheduled oil
change interval. The engine oil change indi-
cator system is duty cycle based, which

Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bagsystem could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper right side of the in-
strument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running
boards.
WARNING!
• It is dangerous to try to repair any part ofthe air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact your authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.

3. While the "Wait to Start" telltale is on, theinstrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information.
4.
After the engine “Wait To Start” telltale goes
off, the engine will automatically crank.
CAUTION!
Do not crank engine for more than 15 seconds
at a time or starter motor damage may result.
Turn the ignition switch to the OFF position
and wait at least two minutes for the starter to
cool before repeating start procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able Geometry Turbocharger at low coolant
temperatures to improve engine warm-up.
• The engine may not automatically crank after the engine "Wait To Start" telltale goes
off if a door or the hood is ajar.
• If the engine stalls, or if the ignition switch is left ON for more than two minutes after
the “Wait To Start Light” goes out, reset the
grid heaters by turning the ignition switch
to the OFF position for at least five seconds
and then back ON. Repeat steps 1 through
7 of “Keyless Enter-N-Go Starting Proce-
dure – Engine Manifold Air Temperature
Below 66° F (19° C).”Extreme Cold Weather
The Cummins diesel engine is equipped with
several features designed to assist cold
weather starting and operation:
• The engine block heater is a resistance
heater installed in the water jacket of the
engine just above and behind the oil filter.
It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire exten-
sion cord.
NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from
your authorized Mopar dealer.
• A 12 Volt heater built into the fuel filter housings aid in preventing fuel gelling. It is
controlled by a built-in thermostat.
• A heated intake air system both improves engine starting and reduces the amount of
white smoke generated by a warming
engine.
STARTING AND OPERATING
124

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.

SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator 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 fre-
quent 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 Op-
erating Conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can bereset by referring to the steps described under
“Warning And Indicator Lights” or “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
Manual at
www.mopar.com/en-us/care/
owner-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for further information.
Gasoline Engines:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
twelve 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 predomi-
nately at idle or very low engine RPM’s. This
type of vehicle use is considered 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
• Check the fluid levels of the coolant reser- voir, brake master cylinder, power steering
and automatic transmission, and fill as
needed
• Check function of all interior and exterior lights
