STARTING PROCEDURES
Before starting your vehicle, adjust your seat, both inside
and outside mirrors, and fasten your seat belts.
The starter is allowed to crank for up to 30-second
intervals. Waiting a few minutes between such intervals
will protect the starter from overheating.
WARNING!
•Before exiting a vehicle, always apply the parking
brake, shift the automatic transmission into PARK
or the manual transmission into REVERSE. Always
make sure the keyless ignition node is in the “OFF”
mode, remove the Key Fob from the vehicle and
lock the vehicle.

WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in
a vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the Key Fob in or near the vehicle (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 con-
trols, or move the vehicle.
NOTE: Engine start up in very low ambient temperature
could result in evident white smoke. This condition will
disappear as the engine warms up.

STARTING AND OPERATING 97

The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for system messages and
warnings.
NOTE:
•Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal
operation.
• The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation and may be audible from the rear of
the vehicle.ADDING FUEL — 1500 DIESEL MODELS

Front Axle – 1500 Four-Wheel Drive
Models We recommend you use MOPAR GL-5 Synthetic Axle Lubricant SAE
75W-85.
Rear Axle We recommend you use MOPAR Synthetic Gear Lubricant SAE 75W-140
(MS-8985). Limited-Slip Rear Axles require the addition of 5 oz. (148 ml)
MOPAR Limited Slip Additive (MS-10111).

will chirp twice (if programmed). In cold ambient tem-
perature conditions, the diesel vehicle may delay crank
up to 30 seconds for the fuel and grid heater. Once the
vehicle has started, the engine will run for 15 minutes or
75 seconds in extreme cold and high elevation.
NOTE:
•The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window and power sunroof op-
eration (if equipped) are disabled when the vehicle is
in the Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the RKE transmitter. However,
the ignition switch must be cycled to the ON position
before you can repeat the start sequence for a third
cycle.To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the REMOTE START button one time or
allow the engine to run for the entire fifteen minute cycle.
NOTE: To avoid unintentional shut downs, the system
will disable the one time push of the REMOTE START
button for two seconds after receiving a valid Remote
Start request.
To Exit Remote Start Mode And Drive The Vehicle
To exit Remote Start Mode and drive the vehicle before
the end of the 15-minute cycle, push and release the
unlock button on the RKE transmitter to unlock the door
and disarm the Vehicle Security Alarm System (if
equipped). Then, prior to the end of the 15-minute cycle,
cycle the ignition to the ON/RUN position.

Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate (engine
power reduction) is activated to protect the turbocharger
during engine start up in cold ambient temperatures.
•Engine Power Reduced During Warmup — This
message will display during start up when the ambi-
ent temperature is between 10° F (-12° C) and -10° F
(-23° C).
• Engine Power Reduced Up To 30 Sec (Seconds)
During Warmup — This message will display during
start up when the ambient temperature is between
-10° F (-23° C) and -25 F (-32° C).
• Engine Power Reduced Up To 2 Min (Minutes)
During Warmup — This message will display during

Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel emissions
standards, resulting in one of the lowest emitting diesel
engines ever produced. To achieve these emissions stan-
dards, your vehicle is equipped with a state-of-the-art
engine and exhaust system. These systems are seamlessly
integrated into your vehicle and managed by the Pow-
ertrain Control Module (PCM). The PCM manages en-
gine combustion to allow the exhaust system’s catalyst to
trap and burn Particulate Matter (PM) pollutants, with no
input or interaction on your part.
