2008 DODGE RAM 2500 GAS Owners Manual

27. 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.
28. 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.
29. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.30. Low Fuel Warning Light
When the fuel level drops to 1/16 tank, the fuel
symbol will light and a single chime will sound.
NOTE:If your vehicle is equipped with an overhead
console module (CMTC), it is possible for DTE to display
ªLO FUELº before the low fuel warning light turns on in
the instrument cluster. This could occur because the low
fuel warning is set to a specified fuel tank volume and
DTE is an estimated distance calculation based on vehicle
fuel economy and remaining fuel tank volume.
Vehicle fuel tank volumes are as follows:
²26 gal (98 L) - 1500 short box models
²34 gal (128 L) - 1500/2500/3500 short box models
²35 gal (132 L) - 1500/2500/3500 long box models

31. CRUISE Light
This indicator lights when the electronic speed control
system is turned on.
32. Coolant Temperature Light ± Base Cluster Only
This light indicates engine coolant temperature is
to high. If the light comes on, stop the vehicle, shift
into NEUTRAL, and increase the engine idle
speed for two to three minutes. If the light does not turn
off, shut your engine OFF and allow it to cool. See an
authorized dealer for service immediately. Refer to
ªCooling Systemº under ªMaintaining Your Vehicleº in
section 7.
CAUTION!
Do not leave your vehicle unattended with the en-
gine running as you would not be able to react to the
temperature indicator if the engine overheats.NOTE:Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
33. Battery Voltage Indicator Light ± Base Cluster
Only
When the engine is running, this light indicates
the electrical system voltage is out of normal
range. This indicator may also illuminate prior to the
voltage gauge moving out of normal range. In either case,
see you local authorized dealer for system service.
34. Oil Pressure Indicator light ± Base Cluster Only
This light indicates continuous high or low oil
pressure, and under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained.

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 ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.

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.
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.
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 six-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.

Electronic Volume Control
The electronic volume control turns continuously (360
degrees) in either direction without stopping. Turning the
volume control to the right increases the volume and to
the left decreases it.
When the audio system is turned on, the sound will be
set at the same volume level as last played.
For your convenience, the volume can be turned down,
but not up, when the audio system is off and the ignition
is ON.
