Dodge 3500 Diesel (2008 year). Manual

experience reduced performance, an elevated/rough idle
or engine stall and your vehicle may require towing. The
light will come on when the ignition is first turned on
and remain on for 15 seconds as a bulb check. If the light
does not come on during starting, have the system
checked by an authorized dealer.

22. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.

23. Water In Fuel Indicator

Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure.

24. Tire Pressure Monitoring Telltale Light — If
Equipped

Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle

placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)

196

UNDERSTANDING YOUR INSTRUMENT PANEL

As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.

197

CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

TPMS “Light Load” Reset Switch – If Equipped

The TPMS ”Light Load” reset switch allows you to
choose between Light Load vehicle conditions and Max
Load vehicle conditions tire pressures and related TPMS
warning levels. The switch is located in the instrument

panel, below the climate control panel. For additional
information refer to “Tire Pressure Monitoring System
(TPMS) — If Equipped” in section 5 of this manual.

25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)

This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high

torque converter slip condition, such as 4-wheel drive
operation (e.g., snow plowing, off-road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.

26. Wait To Start Indicator

The Wait To Start indicator will illuminate when
the ignition is turned to the run position and the
intake manifold temperature is below 66°F (19°C).

198

UNDERSTANDING YOUR INSTRUMENT PANEL

Follow engine starting procedure for proper engine start-
ing and operating. Wait until the Wait To Start indicator
turns OFF, then start the vehicle.

NOTE:

The Wait To Start Indicator may not illuminate if

the engine coolant temperature is warm enough.

27. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.

28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.

29. 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 fuel stations.

Fuel tank volumes are as follows:

• 34 gal (128 L) - 2500/3500 short box models
• 35 gal (132 L) - 2500/3500 long box models

30. 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.

When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.

On the RAQ radio the time button alternates the location
of the time and frequency on the display. On the REF only
one of the two, time or frequency, is displayed at a time.

Clock Setting Procedure

1. Press and hold the time button until the hours blink.

2. Adjust the hours by turning the right side Tune/
Audio control.

3. After the hours are adjusted, press the right side
Tune/Audio control to set the minutes.

4. Adjust the minutes using the right side Tune/Audio
control.

5. To exit, press any button/knob or wait approximately
five seconds.

RADIO GENERAL INFORMATION

Radio Broadcast Signals

The radio will provide excellent reception under most
operating conditions. Like any system, however, automo-
tive radios have performance limitations, due to mobile
operation and natural phenomena, which might lead you
to believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.

200

UNDERSTANDING YOUR INSTRUMENT PANEL

Two Types of Signals

There are two basic types of radio signals: AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary; and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.

Electrical Disturbances

Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.

AM Reception

AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.

FM Reception

Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.

NOTE:

The radio, steering wheel radio controls (if

equipped), and 6-disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned OFF. Opening a vehicle front
door will cancel this feature.
