2017 Ram 2500 light

CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop, with the engine running. Firmly apply the parking brake.
2. Shift the transmission to NEUTRAL.
NOTE: If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. With manual shift transfer case, shift the transfer case lever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models
have a small, recessed “N” button (at the center of the
transfer case switches) that must be pushed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary trans-
fer case control knob. The NEUTRAL (N) indicator light will blink while the shift is in progress. The light
will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual transmissions) for five seconds and ensure that there is
no vehicle movement.
9. Repeat steps 7 and 8 with automatic transmission in DRIVE or manual transmission in first gear.
10. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn OFF the engine. For vehicles with
Keyless Enter-N-Go, push and hold the ENGINE
START/STOP button until the engine shuts off.
11. Shift the transmission into PARK or place manual transmission in gear (NOT in Neutral). On 8-speed
transmissions the shifter will automatically select
PARK when the engine is turned off.

STARTING AND OPERATING 575

12. Turn the ignition to the OFF mode, then cycle theignition to the RUN mode and back to the OFF mode.
Remove the key fob from the ignition.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.
NOTE: With electronic shift transfer case:
• Steps 2 through 4 are requirements that must be met
before pushing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing
the NEUTRAL (N) button or are no longer met during
the shift, the NEUTRAL (N) indicator light will flash
continuously until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met. •
If the vehicle is equipped with air suspension, the engine
should be started and left running for a minimum of 60
seconds (with all the doors closed) at least once every 24
hours. This process allows the air suspension to adjust
the vehicle’s ride height to compensate for temperature
effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it con- nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into NEUTRAL. Depress the clutch pedal on a manual transmission.
• With manual shift transfer case, shift the transfer case
lever to the desired position.
• With electronic shift transfer case with rotary selector
switch, push and hold the transfer case NEUTRAL (N)
button until the NEUTRAL (N) indicator light turns
off. After the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button. After the NEUTRAL
576 STARTING AND OPERATING

(N) button has been released, the transfer case will
shift to the position indicated by the selector switch.
• With electronic shift transfer case with push-button
selector switch, push and hold the switch for the
desired transfer case position, until the NEUTRAL (N)
indicator light turns off and the desired position
indicator light turns on.
NOTE: When shifting out of transfer case NEUTRAL (N),
turning the engine OFF is not required, but may be helpful
to avoid gear clash. With the 8-speed automatic transmis-
sion, the engine must remain running, since turning the
engine OFF will shift the transmission to PARK (and the
transmission must be in NEUTRAL for the transfer case to
shift out of NEUTRAL).
5. Turn the engine OFF. Shift automatic transmission into PARK. On 8-speed transmissions the shifter will auto-
matically select PARK when the engine is turned off.
6. Release the brake pedal (and clutch pedal on a manual transmission).
7. Disconnect vehicle from the tow vehicle.
8. Start the engine. 9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal
(and clutch pedal on manual transmissions), and check
that the vehicle operates normally.
NOTE: With electronic shift transfer case:
• Steps 3 and 4 are requirements that must be met before
pushing the button to shift out of NEUTRAL (N), and
must continue to be met until the shift has been com-
pleted. If any of these requirements are not met before
pushing the button or are no longer met during the shift,
the NEUTRAL (N) indicator light will flash continu-
ously until all requirements are met or until the button is
released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met.

STARTING AND OPERATING 577

Connect the jack tube extension and wheel wrench.
CAUTION!
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE: If the bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the jack
drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the ve- hicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle unstable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the wheel nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and
wheel nuts with the cone shaped end of the wheel nuts
toward the wheel. On 3500 dual rear-wheel models
(DRW) trucks, if the outer tire is being replaced then leave the inner wheel on the vehicle. If the inner wheel
is being replaced remove the outer wheel and replace
the inner wheel. The wheel nuts are a two-piece assem-
bly with a flat face. Lightly tighten the wheel nuts. To
avoid the risk of forcing the vehicle off the jack, do not
fully tighten the wheel nuts until the vehicle has been
lowered.

housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump-
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack, follow
the manufacturer ’s operating instructions and precautions.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
Volts or damage to the battery, starter motor, alternator
or electrical system may occur.
Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE: The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to gain access
to the positive battery post. Do not jump off fuses. Only
jump directly off positive post which has a positive (+)
symbol on or around the post.
618 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
(Continued)
CAUTION! (Continued)
•If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of

WARNING!(Continued)
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Privacy Practices — If
Equipped With Uconnect 8.4 Radio” and “Uconnect Cy-
berSecurity” in “All About Uconnect Access” in your
Owner ’s Manual Radio Supplement and “Cybersecurity”
in “Understanding Your Instrument Panel”.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a loose gascap indicator will dis-
play in the instrument cluster telltale display
area. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and push the SELECT
button to turn off the message. If the problem continues,
the message will appear the next time the vehicle is started. A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, or recently had a dead battery or a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test.

MAINTAINING YOUR VEHICLE 637

Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system isready, you must do the follow-
ing:
1. Cycle the ignition to the ON mode, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition to the ON mode, you will see the “Malfunction Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then return
to being fully illuminated until you cycle the ignition
OFF or start the engine. This means that your vehicle’s
OBD II system is not readyand you should notproceed
to the I/M station. •
The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off posi-
tion or start the engine. This means that your vehicle’s
OBD II system is readyand you can proceed to the I/M
station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.
