Starting
With a valid Keyless Enter-N-Go key fob inside
the vehicle:
1. Shift the transmission into PARK (P).2. While pressing the brake pedal, push the
ENGINE START/STOP button once. If the
engine fails to start, the starter will disen-
gage automatically after 10 seconds.
3. To stop the cranking of the engine prior to the engine starting, push the button again.
NOTE:
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or dead battery. In this situation, a back up
method can be used to operate the ignition
switch. Put the nose side of the key fob (side
opposite of the emergency key) against the
ENGINE START/STOP button and push to op-
erate the ignition button.

AUTOMATIC “SMART” EXHAUST BRAKE
– (DIESEL ONLY)
• Automatic Exhaust Brake technology deliv- ers smoother, less aggressive exhaust brak-
ing characteristics during downhill de-
scents. Although it can apply full exhaust
braking force if needed, Automatic Exhaust
Brake may not apply obvious braking if the
vehicle speed is not increasing. Automatic
Exhaust Brake is intended to maintain ve-
hicle speed while Full Exhaust Brake is in-
tended to reduce vehicle speed.
• Automatic Exhaust Brake can be enabled by pushing the exhaust brake button again any
time after the normal Full Exhaust Brake has
been turned on. The “Exhaust Brake Indica-
tor” in the instrument cluster will change
from yellow to green when Automatic Ex-
haust Brake is enabled. Pushing the exhaust
brake button again will toggle the exhaust
brake mode to off.
Adding Diesel Exhaust Fluid (DEF)
The DEF gauge (located in the instrument clus-
ter) will display the level of DEF remaining in
the tank.
Completely fill the DEF tank through the diesel
exhaust fluid fill location at every maintenance
interval, or before if prompted by the instru-
ment cluster display.
The DEF tank on these vehicles is designed
with a large amount of full reserve. So, the level
sensor will indicate a full reading even before
the tank is completely full. To put it another
way, there’s additional storage capacity in the
tank above the Full mark that’s not represented
in the gauge. You may not see any movement in
the reading – even after driving up to
2,000 miles in some cases.
STARTING AND OPERATING

NOTE:
• Driving conditions (altitude, vehicle speed,load, etc.) will effect the amount of DEF that
is used in your vehicle.
• Another factor is that outside temperature can affect DEF consumption. In cold condi-
tions, 12° F (-11° C) and below, the DEF
gauge needle can stay on a fixed position
and may not move for extended periods of
time. This is a normal function of the sys-
tem.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank. Extra care should be taken when filling
with portable containers to avoid overfilling.
Note the level of the DEF gauge in your
instrument cluster. On pickup applications, you may safely add a maximum of 2 gallons
(7.5 liters) of DEF from portable containers
when your DEF gauge is reading ½ full. On
Chassis Cab applications, a maximum of
2 gallons (7.5 liters) may be added when the
DEF gauge is reading ¾ full.
• There is an electric heater inside the DEF tank that automatically works when neces-
sary. And if the DEF supply does freeze, the
truck will operate normally until it thaws.
• Ensure the DEF cap is reinstalled prior to filling vehicle with diesel fuel to avoid spill-
ing diesel fuel into the DEF Filler.
AUXILIARY SWITCHES
There can be up to five auxiliary switches lo-
cated in the lower switch bank of the instru-
ment panel, which can all be used to power
various electronic devices and PTO (Power Take
Off) – if equipped. Connections to the switches
are found under the hood in the connectors
attached to the auxiliary Power Distribution
Center. The system has the ability to configure the
functionality of the auxiliary switches via the
Instrument Cluster Display. All switches can
now be configured for ignition or battery power,
saving or not saving the state across a key cycle,
and momentary or latching switch operation.

switches, please refer to the Ram Body Builders
