NOTE:
•Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES ONLY
— IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
restart the engine. Vehicles equipped with eTorque contain a heavy duty
motor generator and an additional hybrid electric battery
to store energy from vehicle deceleration for use on engine
startup after a stop as well as providing launch torque
assist.
Automatic Mode
The Stop/Start feature is enabled after every normal cus-
tomer engine start. It will remain in STOP/START NOT
READY until you drive forward with a vehicle speed
greater than 2 mph (3 km/h). At that time, the system will
go into STOP/START READY and if all other conditions
are met, can go into an STOP/START AUTO STOP ACTIVE
“Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster within the Stop/Start section. Refer
to “Instrument Cluster Display” in “Getting To know
Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in DRIVE and the brake pedal depressed.

STARTING AND OPERATING 337

The engine will shut down, the tachometer will move to
the zero position and the stop/start telltale will illuminate
indicating you are in an Autostop. While in an Autostop,
the Climate Controls system may automatically adjust
airflow to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled. In
following situations, the engine will not Autostop:
•Driver ’s seat belt is not buckled.
• Driver ’s door is not closed.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable
cabin temperature has not been achieved.
• HVAC is set to full defrost mode at a high blower speed.
• Engine has not reached normal operating temperature.
• Engine temperature too high.
• The battery is charging.
• The transmission is not in DRIVE. •
Hood is open.
• Vehicle is in 4LO transfer case mode.
• Accelerator pedal input.
• Excessive 12 volt loads.
It may be possible to operate the vehicle several consecu-
tive times in extreme conditions and not meet all criteria to
enable an Autostop state.
To Start The Engine While In Autostop Mode
While in DRIVE, the engine will start when the brake pedal
is released or the throttle pedal is depressed and the
transmission will automatically reengage upon engine
restart.
Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode
The engine will start automatically when:
• The transmission selector is moved from DRIVE to
REVERSE, NEUTRAL, or PARK.
• To maintain cabin temperature near the HVAC settings.
• HVAC is set to full defrost mode.
• 12 volt demand requires engine restart.
338 STARTING AND OPERATING

•Low brake vacuum (e.g. after several brake pedal appli-
cations).
• STOP/START OFF switch is pushed.
• 4WD system is put into 4LO mode.
• The emissions system override is present.
• A STOP/START system error present.
Conditions That Force An Automatic Shift To Park While
In Autostop Mode
The engine will not start automatically and the transmis-
sion will be placed in PARK if:
• The driver door is open and brake pedal released.
• The driver door is open and the driver seat belt is
unbuckled.
• The engine hood has been opened.
• A STOP/START system error present.
The engine may then be restarted by moving the transmis-
sion shift selector out of PARK (e.g. to DRIVE) or, in some
cases, only by a KEY START. The instrument cluster will
display a SHIFT OUT OF PARK message, or a STOP/
START KEY START REQUIRED message, to indicate which
action is required. Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
To Manually Turn Off The Stop Start System
1. Push the STOP/START Off switch (located near the gear
selector). The light on the switch will illuminate.
2. The STOP/START OFF message will appear in the instrument cluster display. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel”
for further information.

3. At the next vehicle stop (after turning off the STOP/START system) the engine will not be stopped.
4. If the STOP/START system is manually turned off, the engine can be started and stopped by cycling the
ignition switch or pressing the STOP/START switch
again.
5. The STOP/START system will reset itself back to an ON condition every time the key is turned off and back on.
To Manually Turn On The Stop Start System
1. Push the STOP/START Off switch (located near the gearselector module).
2. The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
The system will need to be checked by your authorized
dealer.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 20 mph (32 km/h).
The Speed Control buttons are located on the right side of
the steering wheel.
Speed Control Buttons
1 — SET (+)/Accel 4 — SET (-)/Decel
2 — On/Off 5 — CANC/Cancel
3 — RES/Resume
340 STARTING AND OPERATING

To Decrease Speed
While ACC is set, the set speed can be decreased by
pushing the SET(-)button.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (-)button once will result in a 1 mph
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 mph.
• If the button is continually pushed, the set speed will
continue to decrease in 5 mph increments until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.
Metric Speed (km/h)
• Pushing the SET (-)button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is reflected
in the instrument cluster display. NOTE:
•
When you override and push the SET (+)button or SET
(-) buttons, the new set speed will be the current speed
of the vehicle.
• When you use the SET (-)button to decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two seconds
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage the
ACC to the existing set speed.
• The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill.
This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
350 STARTING AND OPERATING

REFUELING THE VEHICLE
The fuel filler is located behind the fuel filler door, on the
left side of the vehicle.
There is no fuel filler cap. Two flapper doors inside the pipe
seal the system.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
1. Put the vehicle in park and switch the ignition off.
2. Push the center-rear edge of the fuel filler door (3 o’clock position) and release to open.

WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable friction
associated with the telescoping motion to dampen any
unwanted trailer swaying motions while traveling.If equipped, the electronic Trailer Sway Control (TSC)
recognizes a swaying trailer and automatically applies
individual wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are the most popular on the market today and they
are commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying leverage
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 provides
for a more level ride, offering more consistent steering and
brake control, thereby enhancing towing safety. The addi-
tion 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

Recommended Distribution Hitch Adjustment
Towing With 1500 Air Suspension
1. Set air suspension to normal ride height. No action isrequired if already in normal ride height.
NOTE: The vehicle must remain in the engine run position
with all doors closed while attaching a trailer for proper
leveling of the air suspension system.
2. Position the truck to be ready to connect to the trailer (do not connect the trailer).
3. Under the instrument cluster or touch screen radio settings, enable tire jack mode. Tire jack mode will be
canceled and procedure must be restarted if the vehicle
is driven at speeds above 5mph (8 kmh).
4. Measure the height of the top of the front wheel opening on the fender to ground, this is height H1. 5. Attach the trailer to the vehicle without the weight
distribution bars connected.
6. Measure the height of the top of the front wheel opening on the fender to ground, this is height H2.
7. Install and adjust the tension in the weight distributing bars per the manufacturers’ recommendations so that
the height of the front fender is approximately (H2-H1)/
3+H1 (about 1/3 the difference between H2 and H1
above normal ride height [H1]).

Trailer Towing Weights (Maximum Trailer Weight
Ratings)
NOTE:For trailer towing information (maximum trailer
weight ratings) refer to the following website addresses:
• ramtrucks.com/en/towing_guide/
• ramtruck.ca (Canada)
• rambodybuilder.com
Trailer And Tongue Weight
Consider the following items when computing the weight
on the rear axle of the vehicle:
•The tongue weight of the trailer.
• The weight of any other type of cargo or equipment put
in or on your vehicle.
• The weight of the driver and all passengers.
NOTE: Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo for
your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
CAUTION!
• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
(Continued)
Weight Distribution
414 STARTING AND OPERATING

CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Perform the maintenance listed in the “Scheduled Servic-
ing”. Refer to “Scheduled Servicing” in “Servicing And
Maintenance” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
• Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
(Continued)
WARNING! (Continued)
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, 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 the
transfer case is not in NEUTRAL. Always, block or
chock the trailer wheels.
• GCWR must not be exceeded.
