starting Ram 2500 2017 Owner's Manual

NOTE:Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/ STOP button must be held for two seconds or three short
pushes in a row with the vehicle speed above 5 mph
(8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position until the
gear selector is in PARK and the button is pushed twice
to the OFF position. If the gear selector is not in PARK
and the ENGINE START/STOP button is pushed once,
the instrument cluster will display a “Vehicle Not In
Park” message and the engine will remain running.
Never leave a vehicle out of the PARK position, or it
could roll. NOTE:
If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.Idle Shutdown — 6.4L Engine Only
This feature can be enabled so that the truck will automati-
cally shutdown when the truck has been idling for a set
period of time when the engine is at operating tempera-
ture. Idle time can be set in 5 minute increments between 5
and 60 minutes. See your local authorized dealer to enable
this feature.
NOTE: The idle shut down timer is disabled while the PTO
is active.5
STARTING AND OPERATING 383

ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN. To
change the ignition switch positions without starting the
vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Push the ENGINE START/STOP button once to changethe ignition to the ACC position.
3. Push the ENGINE START/STOP button a second time to change the ignition to the RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.
Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 10 seconds at a time. Wait 10 to 15
seconds before trying again.
WARNING!
•Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.

384 STARTING AND OPERATING

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to
“Jump-Starting” in “What To Do In Emergencies” for
further information.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking
with the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the ignition button/key
once the engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held
to the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
1500 Models
The engine block heater cord is routed under the hood on
the passenger side of the vehicle near the right head lamp
assembly. It is located between the front grill and the
radiator, but underneath the black upper seal.
2500/3500 Models
The engine block heater cord is routed through the grille by
the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on the
c-clip.
5
STARTING AND OPERATING 385

The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
AUTOMATIC TRANSMISSION
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.
• 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.
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 re-
verse. 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
running. Before exiting a vehicle, always apply the
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 transmission is
locked in PARK, securing the vehicle against un-
wanted 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.
(Continued)
386 STARTING AND OPERATING

WARNING!(Continued)
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• 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 leav-
ing the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be 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 trans-
mission 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 (in 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the LOCK/OFF (key removal)
position. 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 Transmission 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 turned to
the ON/RUN mode (engine running, for vehicles with
eight-speed transmission) and the brake pedal must be
pressed.
In 8-speed vehicles, the brake pedal must also be pressed to
shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds.
5
STARTING AND OPERATING 387

Eight-Speed Automatic Transmission —
If Equipped
The transmission is controlled using a rotary electronic
gear selector located on the instrument panel. The trans-
mission gear range (PRND) is displayed both above the
gear selector and in the instrument cluster. To select a gear
range, simply rotate the gear selector. You must press the
brake pedal to shift the transmission out of PARK, or to
shift from NEUTRAL into DRIVE or REVERSE, when the
vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). To shift past multiple gear ranges at once (such as
Park to Drive), simply rotate the gear selector to the
appropriate detent. Select the DRIVE range for normal
driving.
The electronically-controlled transmission provides a pre-
cise 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 gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE positions. Manual downshifts can
be made using the Electronic Range Select (ERS) shift
control (refer to
Electronic Range Select (ERS) Operation
in this section for further information). Pressing the
GEAR-/GEAR+ switches (on the steering wheel) while in
the DRIVE position will select the highest available trans-
mission gear, and will display that gear limit in the
instrument cluster as 1, 2, 3, etc. Some models will display
both the selected gear limit, and the actual current gear,
while in ERS mode.
388 STARTING AND OPERATING

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold. PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the key fob.

390 STARTING AND OPERATING

CAUTION!
•DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.
• Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
The following indicators should be used to ensure that you
have properly engaged the transmission into PARK:
• With brake pedal released, look at the transmission gear
position display and verify that it indicates the PARK
position (P), and is not blinking.
• With brake pedal released, verify that the gear selector
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop. NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must leave the
vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies” for
further information.

STARTING AND OPERATING 391

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), select TOW/HAUL mode or use
the Electronic Range Select (ERS) shift control (refer to
Electronic Range Select (ERS) Operationin this section for
further information) to select a lower gear range. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE: In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
