cause damage to the vehicle:
Assure that all cargo inside the storage bins
is properly secured.
Do not exceed cargo weight rating of 300 lbs
(136 kg) for 2500 and 3500 series vehicles
per bin.

CAUTION!
Leaving the lid open for extended periods of
time could cause the vehicle battery to
discharge. If the lid is required to stay open
for extended periods of time, it is
recommended that the bin lights be turned
off manually using the on/off switch.

eye irritation, rinse the area with cool water.
For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If
these particles settle on your clothing, follow
the garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
NOTE:
Air bag covers may not be obvious in the inte -
rior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event,
the Occupant Restraint Controller (ORC) will
determine whether to have the Enhanced
Accident Response System perform the
following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on
as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform
any of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circula -
tion Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or
damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system
by following the procedure described below. If
you have any doubt, contact an authorized
dealer.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as well.

246STARTING AND OPERATING
AUXILIARY SWITCHES — IF EQUIPPED
There can be up to six auxiliary switches located
in the lower switch bank of the instrument panel
which can be used to power various electronic
devices and PTO (Power Take Off) – If Equipped.
If Power Take Off is equipped, it will take the
place of the sixth Auxiliary switch. Connections
to the switches are found under the hood in the
connectors attached to the auxiliary Power
Distribution Center.
You have the ability to configure the
functionality of the auxiliary switches via the
instrument cluster display. All switches can now
be configured for setting the switch type
operation to latching or momentary, power
source of either battery or ignition, and ability to
hold last state across key cycles.
NOTE:
Holding last state conditions are met when
switch type is set to latching and power source
is set to ignition.
For further information on using the auxiliary
switches, please refer to the Ram Body Builders
Guide by accessing www.rambodybuilder.com
and choosing the appropriate links.
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise
Cancellation system that cannot be turned off.
This system is designed to address exhaust and
engine noise. The system relies on four
microphones embedded in the headliner, which
monitor exhaust and engine noise, and assists
an onboard frequency generator, which creates
counteracting sound waves in the audio
system’s speakers. This helps keep the vehicle
quiet at idle and during drive. The system is
deactivated when the windows are rolled down.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with
either a manually shifted transfer case or an
electronically shifted transfer case. Refer to the
operating instructions for your transfer case,
located in this section for further information.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (EIGHT SPEED TRANSMISSION) —

F EQUIPPED
This is an electronic shift transfer case and is
operated by the 4WD Control Switch (Transfer
Case Switch), which is located on the
instrument panel.

Four-Position Transfer Case

This electronically shifted transfer case
provides four mode positions:
Two-Wheel Drive High Range (2WD)
Four-Wheel Drive High Range (4WD HIGH)
Four-Wheel Drive Low Range (4WD LOW)
N (Neutral)

382IN CASE OF EMERGENCY
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
bumpers or associated brackets. State and
local laws regarding vehicles under tow must be
observed.
If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode. If the key fob is unavailable or the vehicle's
battery is discharged, refer to ”Manual Park
Release” in this section for instructions on
shifting the transmission out of PARK for
towing.TWO-WHEEL DRIVE MODELS
The manufacturer recommends towing your
vehicle with all four wheels
OFF the ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
