level, or OFF. The High heat level operates for 30 minutes
(approximate), the Low heat level operates for 30 min-
utes (approximate). The seat heat will also turn OFF
when the ignition is turned OFF. Both of the indicators
ON identifies High heat level. The lower indicator On
only, identifies Low heat level. Flashing indicator lights
on the switch indicate that the Heated Seat System needs
servicing.WARNING!
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat.

storage area into separate compartments. Lift the lower
handle on the front of the armrest, and raise the armrest
for access to the lower storage bin. On Quad Cab and
Mega Cab models the rear of the floor console offers a
power outlet, a tip out bin and a rear air duct (Mega Cab
Only).
WARNING!
•This armrest is not a seat. Anyone seated on the
armrest could be seriously injured during vehicle
operation, or an accident. Only use the center
seating position when the armrest is fully upright.
•In an accident, the latch may open if the total
weight of the items stored exceeds about 10 lbs
(4.5 kg). These items could be thrown about
endangering occupants of the vehicle. Items
stored should not exceed a total of 10 lbs (4.5 kg).
CAUTION!
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.

CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for 6 to 8 seconds
when the ignition is first turned on. If the light stays on,
flickers or comes on while driving, have the airbag
system checked by an authorized dealer.
6. High Beam Indicator This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
During the bulb check, if the driver’s seat belt is unbuckled, a chime will sound. After the bulb check or
when driving, if the driver seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to
Enhanced Driver Seat Belt Re-
minder System (BeltAlert™) in the Occupant Restraints
section for more information. (See page 31 for more
information.)
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.
9. Oil Pressure Gauge The pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained. (See page 383 for more
information.)

30. Low Fuel Warning Light Glows when the pointer is between “E” and 1/8
indication mark (approximately 15% of tank vol-
ume) on the fuel gauge. When the fuel gauge
pointer is on “E” (equivalent to Distance To Empty [DTE]
= 0 on the overhead console if so equipped) there is
reserve fuel capacity, which corresponds to approxi-
mately 8% of tank volume. This reserve capacity was put
in place to prevent the likelihood of customers running
out of fuel when operating at maximum load conditions
in areas where there aren’t many gas stations. (See page
139 for more information.)
Ram fuel tank volumes are as follows:
•34 gallons - 2500/3500 short box models
•35 gallons - 2500/3500 long box models 31. Door Ajar
The Door Ajar light will illuminate when any
door is opened. When the ignition is ON the
Door Ajar light will stay illuminated until the
open door is closed. When the ignition is OFF
the Door Ajar light will stay illuminated until the open
door is closed or the battery saver feature automatically
turns the light off.
32. CRUISE Light
This indicator lights when the electronic speed control
system is turned on.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the frequency and/or
time in hours and minutes (depending on your radio
model) whenever the ignition switch is in the “ON” or
“ACC” position.

Starting Fluids
WARNING!
STARTING FLUIDS or flammable liquids are
NEVER TO BE USED in the Cummins Diesel (see
Warning label). Never pour diesel fuel, flammable
liquid, starting fluids (ether) into the air cleaner
canister, air intake piping, or turbocharger inlet in an
attempt to start the vehicle. This could result in a
flash fire and explosion causing serious personal
injury and engine damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
NORMAL OPERATION (DIESEL ENGINE)
Observe the following when the engine is operating.
•All message center lights are off.
•Check Engine Lamp is off.
•Engine Oil Pressure is above 10 psi (69 kPa) at idle.

Transfer Case Position Indicator Lights —
Electronically Shifted Transfer Case Only
Transfer case position indicator lights are located in the
instrument cluster and indicate the current and desired
transfer case selection. When you select a different trans-
fer case position, the indicator lights will do the follow-
ing:
If All Shift Conditions are Met
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer 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 (5)
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section of the owner’s manual.
The “SERVICE 4WD” warning light monitors the electric
shift 4WD system. If this light remains on after engine
start up or illuminates during driving, it means that the
4WD system is not functioning properly and that service
is required.

actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights & Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may includ ea4and7pin
wiring harness. Use a factory approved trailer harness
and connector.
