2009 RAM CHASSIS CAB fuel

Airbag Warning Light
The airbag warning light should come on, and remain on,
for six to eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not lit during
starting, see your authorized dealer. If the light stays on,
flickers or comes on while driving, have the system
checked by an authorized dealer. If there is a problem
with the airbag warning light, the seat belt light will
flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.
Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.

Step Button
Use this button to choose or cycle through the four trip
conditions.
Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset.
Average fuel economy is a running average of the
amount of fuel used and the distance the vehicle has
traveled.
When the fuel economy is reset, the display will momen-
tarily blank. Then the history will be erased and the
AVERAGING WILL CONTINUE FROM WHERE IT
WAS BEFORE THE RESET. The reset value is based on a
minimal amount of fuel used and the distance traveled
from the previous drive cycle. The displaymay take
several miles/kilometers for this value to change, depen-
dent upon driving habits.

Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to an alternating text display of “LO” and “FUEL.” This
display will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the “LO FUEL” text and a new DTE value will be
displayed, based on the current values in the DTE
calculation and the current fuel tank level. NOTE:
It is possible for DTE to display “LO FUEL”
before the low fuel warning light turns on in the instru-
ment cluster. This could occur because low fuel warning
is set to a specified fuel tank volume and DTE is an
estimated distance calculation based on fuel economy
and remaining fuel tank volume.
Ram fuel tank volumes are as follows:
•52 gal (196 L) - Standard rear tank
•22 gal (83 L) - Optional midship tank
Trip Odometer (ODO)
NOTE: The maximum value is approximately
6,000 miles (9,657 km). Then the trip odometer must be
reset in order to update the trip odometer miles/
kilometers.

INSTRUMENT CLUSTER DESCRIPTION
1. Check GaugesThis light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:
•If the gauge pointer moves to either extreme of the
gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
•The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the engine
control module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
3. Turn Signal Indicators Lights in instrument cluster flash when outside turn
signals are operating.

18. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (MIL) 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 five seconds, and remain on
until the vehicle is started. If the bulb does not come on
during starting, have the condition 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 authorized 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 drivability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
19. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
168 UNDERSTANDING YOUR INSTRUMENT PANEL

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 IndicatorThe 4WD indicator will be illuminated when-
ever 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. Transmission Temperature Indicator (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.
24. 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.
25. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
