automatic transmission Ram 3500 2017 Diesel Supplement

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
The starter should not be operated for more than 15-second
intervals. Waiting a few minutes between such intervals
will protect the starter from overheating.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock 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 gear
selector.

STARTING AND OPERATING 121

Keyless Enter-N-Go — If Equipped
This feature allows the driver to operate
the ignition switch with the push of a
button, as long as the Remote Start/
Keyless Enter-N-Go key fob is in the
passenger compartment.
Normal Starting
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing theENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will disengage
automatically after 25 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, remove your foot from the brake
pedal and push the button again. NOTE:
•
Normal starting of either a cold or a warm engine is
obtained without pumping or pressing the accelerator
pedal.
• Under cold weather conditions, the engine may not
immediately crank if the Wait To Starttelltale is
illuminated. This is normal operation. For vehicles
equipped with Keyless Enter-N-Go, the vehicle will
automatically crank when the Wait To Starttime has
elapsed. See the section Starting Procedure Engine

Button
1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition will return to the OFF position.
122 STARTING AND OPERATING

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 display 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.
4. If the gear selector is in NEUTRAL, push and release the ENGINE START/STOP button with the vehicle speed
below 5 mph (8 km/h) before the engine will shut off.
The ignition will remain in the ACC position. NOTE:
If the ignition 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.
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

minutes for the starter to cool before repeating start
procedure.
5. When the engine starts, release the key fob.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
Starting Procedure — Engine Manifold Air
Temperature 0°F To 66°F (–18°C to 19°C)
NOTE: The temperature displayed in the instrument clus-
ter does not necessarily reflect the engine manifold air
temperature. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation. When engine temperatures fall below 66°F (19°C)
the “Wait To Start Light” will remain on indicating the
intake manifold heater system is active.
126 STARTING AND OPERATING

NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
• The fuel grade should be clearly marked on the pump at
the fuel station.
• The engine requires the use of “Ultra Low Sulfur Diesel
Fuel”. Use of incorrect fuel could result in engine and
exhaust system damage. Refer to “Fuel Requirements”
in “Starting And Operating” for further information.
• If climatized or diesel Number 1 ULSD fuel is not
available, and you are operating below (20°F/-6°C), in
sustained arctic conditions, Mopar Premium Diesel Fuel
Treatment (or equivalent) is recommended to avoid
gelling (see Fuel Operating Range Chart).
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Cover Usage
A winter front or cold weather cover is to be used in
ambient temperatures below 32°F (0°C), especially during
extended idle conditions. This cover is equipped with four
flaps for managing total grille opening in varying ambient
temperatures. If a winter front or cold weather cover is to
be used the flaps should be left in the full open position to
allow air flow to the charge air cooler and automatic
transmission oil cooler. When ambient temperatures drop
below 0°F (-17°C) the four flaps need to be closed. A
suitable cold weather cover is available from your MOPAR
dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPAR dealer.
132 STARTING AND OPERATING

Engine Warm-Up
Avoid full throttle operation when the engine is cold. When
starting a cold engine, bring the engine up to operating
speed slowly to allow the oil pressure to stabilize as the
engine warms up.
NOTE:High-speed, no-load running of a cold engine can
result in excessive white smoke and poor engine perfor-
mance. No-load engine speeds should be kept under 1,200
RPM during the warm-up period, especially in cold ambi-
ent temperature conditions.
Your vehicle is equipped with a turbo speed limiter, this
feature limits the engine speed to 1,200 RPM when engine
coolant temperatures are below 70°F (21°C). This feature is
designed to protect the turbocharger from damage and will
only operate in PARK or NEUTRAL.
If temperatures are below 32°F (0°C), operate the engine at
moderate speeds for five minutes before full loads are
applied.
NOTE: If ambient temperatures are low and the coolant
temperature is below 180°F (82°C), the engine idle speed
will slowly increase to 1,000 RPM after two minutes of idle,
if the following conditions are met:
• Foot is off brake pedal and throttle pedal. •
Automatic transmission is in PARK.
• Vehicle speed is 0 mph (0 km/h).
• Applying the throttle will cancel fast idle.
• Operating the exhaust brake at idle will greatly improve
warm up rate and will help keep the engine close to
operating temperature during extended idle.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber tem-
peratures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, engine valves, and injector
nozzles. Also, the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the engine.
If the engine is allowed to idle or the truck is driven on low
engine speed drive cycles for more than 2 hours, the
system will automatically enter an emissions operating
mode that will increase the engine idle speed to 900 RPM
(1050 RPM for Chassis Cab). While in this mode, which is
designed to help maintain the diesel particulate filter, the
engine idle speed will return to normal when the brake
pedal is applied. A small change in engine tone or a slight
change in engine performance while accelerating may also5
STARTING AND OPERATING 133

be noticeable at speeds below 20 mph (32 kmh). This
operating mode may last for up to an hour of idle time, or
around 20 minutes of driving time.
Your truck may have been ordered with an optional
voltage monitoring idle up feature. If a load is placed on
the electrical system while the truck is in park, this feature
will attempt to maintain normal system voltage by auto-
matically increasing engine idle speed. You may notice
several consecutive increases in idle speed, up to a maxi-
mum of 1450 RPM, as the system will attempt to utilize the
smallest increase in idle speed necessary to maintain
normal system voltage. The idle speed will return to
normal when either the electrical load is removed, or when
the brake pedal is applied.
NOTE:For instrument cluster display messages related to
the vehicle’s exhaust system, refer to “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.
Idle-Up Feature — Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional cab
heat, however, excessive idling may still cause the exhaust
aftertreatment system to not properly regenerate. Extended
periods of idle time should be avoided. The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehicle’s
interior.
1. With the transmission in PARK, the parking brake
applied, and the engine running, push the speed control
switch to the ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the ACCEL/RESUME switch and
the idle speed will increase to approximately 1500 RPM.
To decrease the RPM, push and hold the DECEL switch
and the idle speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF switch, or press the brake
pedal.
Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially important
for turbocharged, charge air-cooled engines.
134 STARTING AND OPERATING

Programmable Maximum Vehicle Speed (Chassis
Cab Only)
This feature allows the owner to set a maximum vehicle
speed for the vehicle. The 3500 Series maximum vehicle
speed can be set between 40 mph (64 km/h) and 87 mph
(140 km/h). The 4500/5500 Series maximum vehicle speed
can be set between 40 mph (64 km/h) and 85 mph
(136 km/h). See your local authorized dealer to enable this
feature.
NOTE:DO NOT set the maximum vehicle speed to a value
greater than what the vehicle tires are rated for.
Operating Precautions
Avoid Overheating The Engine
The temperature of the engine coolant (antifreeze) (a
mixture of 50% ethylene-glycol and 50% water) must not
exceed the normal range of the temperature gauge 240°F
(116°C) with a 21 psi (145 kPa) coolant pressure cap.
Usually the engine coolant (antifreeze) temperature indi-
cated during operation will be to the left of center in the
normal range of the gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low engine coolant (antifreeze)
temperature below the normal range on the gauge 140°F
(60°C) can be harmful to the engine. Low engine coolant
(antifreeze) temperature can cause incomplete combustion
which allows carbon and varnish to form on piston rings
and injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the lubricating oil and causing rapid
wear to the engine.
Cooling System Tips — Automatic Transmission
To reduce potential for engine and transmission overheat-
ing in high ambient temperature conditions, take the
following actions:
• City Driving —
When stopped, shift the transmission into NEUTRAL and
increase engine idle speed.
• Highway Driving —
Reduce your speed.
• Up Steep Hills —
Select a lower transmission gear.
• Air Conditioning —
Turn it off temporarily.
136 STARTING AND OPERATING

pressure from the accelerator pedal. Exhaust braking is
most effective when the engine RPM is higher. The auto-
matic transmission will downshift more aggressively in
TOW/HAUL mode when the exhaust brake is enabled to
increase brake performance.
CAUTION!
Use of aftermarket exhaust brakes is not recommended
and could lead to engine damage
WARNING!
Do not use the exhaust brake feature when driving in
icy or slippery conditions as the increased engine
braking can cause the rear wheels to slide and the
vehicle to swing around with the possible loss of
vehicle control, which may cause an accident possibly
resulting in personal injury or death.
NOTE: For optimum braking power it is recommended to
use the exhaust brake while in TOW/HAUL mode. The exhaust brake feature can also be used to reduce the
engine warm up time. To use the exhaust brake as a
warm-up device, the vehicle must be stopped or moving
less than 5 mph (8 km/h), the
Exhaust Brake Indicator
must be on, and the coolant temperature must be below
180°F (82°C) and ambient temperature below 60°F (16°C).
Automatic Smart Exhaust Brake (Auto)
Automatic Exhaust Brake technology delivers smoother,
less aggressive exhaust braking characteristics during
downhill descents. Although it can apply full exhaust
braking force if needed, Automatic Exhaust Brake may not
apply obvious braking if the vehicle speed is not increas-
ing. Automatic Exhaust Brake is intended to maintain
vehicle speed, while Full Exhaust Brake is intended to
reduce vehicle speed.
Automatic Exhaust Brake can be enabled by pushing the
exhaust brake button again anytime after the normal Full
Exhaust Brake has been turned on. The “Exhaust Brake
Indicator” in the instrument cluster display will change
from Yellow to Green when Automatic Exhaust Brake is
enabled. Pushing the exhaust brake button again will
toggle the exhaust brake mode to off.

AUTOMATIC TRANSMISSION — IF EQUIPPED
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.
(Continued)
WARNING! (Continued)
•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.
• 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.
