2015 Ram 3500 lights

This electronically shifted transfer case provides four
mode positions:
•Two-wheel drive high range (2WD)
• Four-wheel drive lock range (4WD LOCK)
• Four-wheel drive low range (4WD LOW)
• Neutral (NEUTRAL)
This electronically shifted transfer case is designed to be
driven in the two-wheel drive position (2WD) for normal
street and highway conditions on dry, hard surfaced roads.
When additional traction is required, the transfer case 4WD
LOCK and 4WD LOW positions can be used to maximize
torque to the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to the desired position.
Refer to “Shifting Procedure” in this section for specific
shifting instructions. The 4WD LOCK and 4WD LOW
positions are designed for loose, slippery road surfaces only. Driving in the 4WD LOCK and 4WD LOW positions
on dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.
NOTE:
The transfer case NEUTRAL position is selected
by pushing the button located on the lower left hand
corner of the 4WD Control Switch. The transfer case
NEUTRAL position is to be used for recreational towing
only. Refer to “Recreational Towing” in “Starting And
Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate
the current and desired transfer case selection. When you
select a different transfer case position, the indicator
lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
492 STARTING AND OPERATING

•The ignition switch must be in the ON position for a
shift to take place and for the position indicator lights
to be operable. If the ignition switch is not in the ON
position, the shift will not take place and no position
indicator lights will be on or flashing.

the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.
This electronically shifted transfer case provides five
mode positions:
•Two-wheel drive high range (2WD)
• Four-wheel drive automatic range (4WD AUTO)

Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD,
4LOW, and 4WD AUTO) are located in the instrument
cluster and indicate the current and desired transfer case
selection. When you select a different transfer case posi-
tion, the indicator lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain ON. 2. The newly selected position indicator light will con-
tinue to flash.
3. The transfer case will notshift.
NOTE: Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.

NOTE:The transfer case NEUTRAL position is selected
by pushing the recessed button (with a ballpoint pen or
similar object) located in the center of the 4WD Control
Switch. The transfer case NEUTRAL position is to be

button once from the NRH while the vehicle speed is
below 33 mph (53 km/h). Once the vehicle speed goes
below 15 mph (24 km/h) the vehicle height will begin
to lower. If the vehicle speed remains between 15 mph
(24 km/h) and 25 mph (40 km/h) for greater than 60
seconds, or the vehicle speed exceeds 25 mph
(40 km/h) the Entry/Exit change will be cancelled. To
return to Normal Height Mode, push the “Up” button
once while in Entry/Exit or drive the vehicle over
15 mph (24 km/h). Entry/Exit mode may not be
available due to vehicle payload, an EVIC/DID mes-
sage will be displayed when this occurs. Refer to
“Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your
key fob for easier entry/loading. Refer to “A Word About
Your Keys” in “Things To Know Before Starting Your
Vehicle” for further information. •
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance re-
quired for certain areas and vehicle damage may
occur.
The system requires that the ignition be in ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors,
must be closed. If a door is opened at any time while the
vehicle is lowering the change will not be completed
until the open door(s) is closed.
This system uses a lifting and lowering pattern which
keeps the headlights from incorrectly shining into on-
coming traffic. When raising the vehicle, the rear of the
vehicle will move up first and then the front. When
lowering the vehicle, the front will move down first and
then the rear.

CAUTION!
The door sill height is 25 inches. Water may intrude
into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultane-
ous use of the brake and throttle (two footed driving).
When climbing rocks, logs, or other stepped objects,
using light brake pressure with light throttle will keep the
vehicle from jerking or lurching. This technique is also
used when you need to stop and restart a vehicle on a
steep incline.
The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard packed dirt, gravel, rocks, grass, sand,mud, snow and ice. Every surface has a different effect on
your vehicle’s steering, handling and traction. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheel
and maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases there are no
road signs, posted speed limits or signal lights. Therefore
you will need to use your own good judgment on what is
safe and what isn’t. When on a trail you should always be
looking ahead for surface obstacles and changes in
terrain. The key is to plan your future driving route while
remembering what you are currently driving over.
CAUTION!
Never park your vehicle over dry grass or other
combustible materials. The heat from your vehicle
exhaust system could cause a fire.
528 STARTING AND OPERATING

NOTE:
•An aftermarket controller may be available for use
with trailers with air or electric-over-hydraulic trailer
brake systems. To determine the type of brakes on
your trailer and the availability of controllers, check
with your trailer manufacturer or dealer.
• Removal of the ITBM will cause errors and it may
cause damage to the electrical system and electronic
modules of the vehicle. See your authorized dealer if
an aftermarket module is to be installed.Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
