•The vehicle will only be capable of a maximum speed
of 5 MPH upon the first of the following conditions to
occur:
•If the vehicle is shutoff and restarted.
•If the vehicle is idled for an extended period of time,
approximately one hour or greater.
•If the system detects that the level of fuel in the tank
has increased.
•5 MPH Max Speed Service DEF System See Dealer—
This message will continuously display, and will be
accompanied by a periodic chime. Although the ve-
hicle can be started and placed in gear, the vehicle will
only operate at a maximum speed of 5 MPH. Your
vehicle will require towing, see your authorized dealer
for service.
NOTE:When this message is displayed, the engine can
still be started. However, the vehicle will only operate at
a maximum speed of 5 MPH.RAM Active Air System
Your vehicle is equipped with an advanced Ram Active
Air system that provides enhanced performance, espe-
cially when towing under demanding hot or high alti-
tude conditions. If the EVIC displays the message “Ac-
tive Airbox Service Required See Dealer”, vehicle
performance may be reduced until service is performed
by an authorized RAM dealer.
Fuel Filter Life Reset
The cluster will display the “Service Fuel Filter” message
when the fuel filter maintenance life is less than 5%. To
check the remaining fuel filter life, go to the “Fuel Filter
Life” screen in the “Vehicle Info” menu. When this
message appears, dealers should replace both frame
mounted and engine mounted fuel filters.
NOTE:Use the steering wheel EVIC controls for the
following procedure(s)

7. Press and release theUparrow button to exit the EVIC
screen once the Fuel Filter Life is 100%
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
Oil Life Reset
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10
seconds after a single chime has sounded, to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent
upon your personal driving style.
NOTE:Use the steering wheel EVIC controls for the
following procedure(s)Vehicles Equipped With Passive Entry
1. Without pressing the brake pedal, press the ENGINE
START/STOP button and cycle the ignition to the
ON/RUN position (do not start the engine.)

The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The shift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of PARK (refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
Pull the shift lever toward you when shifting into RE-
VERSE or PARK, or when shifting out of PARK.
The electronically-controlled transmission provides a
precise shift schedule. The transmission 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 between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer toElectronic Range Select (ERS)
Operationin this section for further information). Press-
ing the ERS (-/+) switches (on the shift lever) while in the
DRIVE position will select the highest available transmis-
sion gear, and will display that gear in the instrument
cluster as 1, 2, 3, etc.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.

Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads to distribute trailer tongue weight to the
tow vehicle’s front axle and the trailer axle(s). When used
in accordance with the manufacturer’s directions, it pro-
vides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
WARNING!
•An improperly adjusted Weight Distributing Hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
•Weight Distributing Systems may not be compat-
ible with Surge Brake Couplers. Consult with your
hitch and trailer manufacturer or a reputable Rec-
reational Vehicle dealer for additional information.
Fifth-Wheel Hitch
The fifth-wheel hitch is a special high platform with a
coupling that mounts over the rear axle of the tow vehicle
in the truck bed. It connects a vehicle and fifth-wheel
trailer with a coupling king pin.

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 dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
•Safety chains must always be used between 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

•GCWR must not be exceeded.
•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

sliding the manual brake control lever will display the
GAIN setting for 10 seconds and the “Trailer Brake Status
Indicator Light” will not be displayed.
If a fault is detected in the trailer wiring or the Integrated
Trailer Brake Module (ITBM), the “Trailer Brake Status
Indicator Light” will flash.
GAIN Adjustment Buttons (+/-)
Pressing these buttons will adjust the brake control
power output to the trailer brakes in 0.5 increments. The
GAIN setting can be increased to a maximum of 10 or
decreased to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control
for the specific towing condition and should be changed
as towing conditions change. Changes to towing condi-
tions include trailer load, vehicle load, road conditions
and weather.Adjusting GAIN
NOTE:This should only be performed in a traffic free
environment at speeds of approximately 20–25 mph
(30–40 km/h).
1. Make sure the trailer brakes are in good working
condition, functioning normally and properly ad-
justed. See your trailer dealer if necessary.
2.
Hook up the trailer and make the electrical connections
according to the trailer manufacturer’s instructions.
3. When a trailer with electric/EOH brakes is plugged
in, the trailer connected message should appear in the
EVIC (if the connection is not recognized by the ITBM,
braking functions will not be available), the GAIN
setting will illuminate and the correct type of trailer
must be selected from the EVIC options.
4. Press the UP or DOWN button on the steering wheel
until “TRAILER TOW” appears on the screen.

5. Press the RIGHT arrow on the steering wheel to enter
“TRAILER TOW”.
6. Press the UP or DOWN buttons until Trailer Brake
Type appears on the screen.
NOTE: 1500 Models Only— Light Electric and Heavy
Electric will only be available due to the tow capacities of
the vehicle.
7. Press the RIGHT arrow and then press the UP or
DOWN buttons until the proper Trailer Brake Type
appears on the screen.8.In a traffic-free environment, tow the trailer on a dry,
level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing
tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier
trailer, trailer wheel lockup may not be attainable even
with the maximum GAIN setting of 10.
