2007 DODGE RAM 2500 DIESEL instrument panel

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.

When the ignition switch is in the “OFF” position, or
when the radio frequency is being displayed, time keep-
ing 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
5 seconds.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration 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.
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.
188 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
