STARTING THE ENGINE — GASOLINE
ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belt.
The starter should not be operated for more
than 10-second intervals. Waiting a few sec-
onds between such intervals will protect the
starter from overheating.
WARNING!
• When leaving the vehicle, always makesure the keyless ignition node is in the
"OFF" mode, remove the key fob from
the vehicle and lock the vehicle.
• 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 gear selector.
WARNING!
• Do not leave the key fob in or near thevehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
Normal Starting
Normal starting of either a warm or cold
engine is obtained without pumping or press-
ing the accelerator pedal. Cycle the ignition
to the RUN position and release when the
engine starts. If the engine fails to start
within 10 seconds, cycle the ignition to the
OFF position, wait five seconds, then repeat
the “Normal Starting” procedure.

move your foot from the brake pedal and
push the button again. NOTE:
• Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
• Under cold weather conditions, the engine may not immediately crank if the "Wait To
Start" telltale is illuminated. This is normal
operation. For vehicles equipped with Key-
less Enter-N-Go, the vehicle will automati-
cally crank when the "Wait To Start" time
has elapsed. See the section "Starting Pro-
cedure Engine Manifold Air Temperature
0°F to 66°F (18° C to 19°C)" in the Diesel
Supplement for more information.

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

• 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.

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.
