CAUTION!Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on. If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicates UNDERSTANDING YOUR INSTRUMENT PANEL 177
4
Page 178 of 532

that the anti-lock portion of the brake system is not
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed.
20. Electronic Throttle Control (ETC)
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may 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.
21. 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.
22. Front Fog Light Indicator — If Equipped
This light shows when the front fog lights are ON.178 UNDERSTANDING YOUR INSTRUMENT PANEL

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 gas stations. (See page
136 for more information.)
Ram fuel tank volumes are as follows:
• 52 gallons - Standard Rear Tank
• 22 gallons - Optional Mid Ship Tank 30. 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.
31. 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.180 UNDERSTANDING YOUR INSTRUMENT PANEL
Page 181 of 532

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. UNDERSTANDING YOUR INSTRUMENT PANEL 181

RND/SET Button (Radio Mode) To SET The
Push-Button Memory
When you are receiving a station that you wish to
commit to push-button memory, press the SET button.
The symbol SET 1 will now show in the display window.
Select the button (1-6) you wish to lock onto this station
and press and release that button. If a button is not selected within 5 seconds after pressing the SET button,
the station will continue to play but will not be stored
into push-button memory.
You may add a second station to each push-button by
repeating the above procedure with this exception: Press
the SET button twice and SET 2 will show in the display
window. Each button can be set for SET 1 and SET 2 in
both AM and FM. This allows a total of 12 AM, 12 FM,
and 12 Satellite (if equipped) stations to be stored into
push-button memory. The stations stored in SET 2
memory can be selected by pressing the push-button
twice.
Every time a preset button is used, a corresponding
button number will display.
Preset Button s1-6( Radio Mode)
These buttons tune the Radio to the stations that you
commit to push-button memory {12 AM, 12 FM, and 12
Satellite (if equipped) stations}.186 UNDERSTANDING YOUR INSTRUMENT PANEL
