2008 DODGE RAM 4500 CHASSIS CAB light

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.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound.
14. Security Light
The light will flash rapidly for approximately 16 seconds
when the vehicle theft alarm is arming. The light willflash at a slower rate after the alarm is set. The security
light will also come on for about two seconds when the
ignition is first turned ON.
15. Transmission Range Indicator (Automatic
Transmissions Only)
When the gear selector lever is moved, this indicator
shows the automatic transmission gear range selected.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed
during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.

seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
1. Turn the ignition switch to the ON position(Do not
start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
17. Front Fog Light Indicator Ð If Equipped
This light shows when the front fog lights are ON.
18. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.

If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
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.19. 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.
20. 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
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.21. 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.
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 Ð Diesel Only
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure.(See page 417 for more infor-
mation.)
24. 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 thislight comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
25. Wait To Start Indicator Ð Diesel Only
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
intake manifold temperature is below 66 degrees F.
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. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
28. Low Fuel Warning Light
Glows when the pointer is between ªEº and 1/8
indication mark (approximately 15% of tank vol-
ume) on the fuel gauge. When the fuel gauge
pointer is on ªEº (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
137 for more information.)Ram fuel tank volumes are as follows:
²52 gallons - Standard Rear Tank
²22 gallons - Optional Mid Ship Tank
29. 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 ªONº or
ªACCº position.
When the ignition switch is in the ªOFFº position, or
when the radio frequency is being displayed, time keep-
ing is accurately maintained.

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.
