2007 RAM CHASSIS CAB battery

• AVG. MPG – Shows the average fuel economy since
the last reset. When the fuel economy is reset, the
display will show dashes for two seconds. Then the
history information will be erased, and the averaging
will continue from the last fuel average reading before
the reset. (Example: If your Electronic Vehicle Informa-
tion Center (EVIC) displays 18 AVG. MPG and the
RESET button is pressed, the previous averaging his-
tory will be erased and the display will return to the 18
AVG. MPG, not to 0 AVG. MPG). The display may take
several miles for the value to change dependent upon
driving habits.
• MI TO EMPTY (Distance To Empty) – Shows the
estimated distance that can be traveled with the fuel
remaining in the tank. This estimated distance is
determined by a weighted average of fuel economy,
according to the current fuel tank level. Distance MI
TO EMPTY cannot be reset through the RESET button. 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 a text display of  LOW 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  LOW FUEL  text and a new DTE value will
display.
System Status (EVIC Displays)
When the appropriate conditions exist, the Electronic
Vehicle Information Center (EVIC) displays the following
messages:
• TURN SIGNALS ON (with a continuous warning
chime)
• RKE BATTERY LOW (with a single chime) UNDERSTANDING THE FEATURES OF YOUR VEHICLE 143

There is an additional Power Outlet inside the center
console of vehicles equipped with 40/20/40, or Bucket
front seats. There is also a Power Outlet located on the
rear of the center console for Quad Cab or Mega Cab
vehicles (only) equipped with bucket seats.
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE: If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only. CAUTION!Electrical Outlet Use With Engine Off
• Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
• Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
• After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

removable coin holder (if equipped), and two dividers to
configure the storage area into compartments. For ex-
ample, compartments can be configured to hold a lap-top
computer, a cellular telephone, CD’s and miscellaneous
items. The top of the cover provides a generous firm
surface to serve as a desktop for your “mobile office.”
WARNING!• This armrest is not a seat. Anyone seated on the
armrest could be seriously injured during vehicle
operation, or an accident. Only use the center
seating position when the armrest is fully upright.
• In an accident, the latch may open if the total
weight of the items stored exceeds about 10 lbs
(4.5 kg). These items could be thrown about
endangering occupants of the vehicle. Items
stored should not exceed a total of 10 lbs (4.5 kg). CAUTION!• Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will

Located in the center of the front 40/20/40 seat cushion
there is a storage compartment.
Standard cab models also have storage behind the seat.
The Quad Cab models provide additional storage under
the rear seat. Lift the seat to access the storage compart-

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages 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 Gages” indicator will illuminate
and a single chime will sound.
NOTE:
• The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This cy-
cling 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, this time will not exceed
150 seconds. The needle should then stabilize at the
approximate operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.172 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

sists of a DVD player and LCD (liquid crystal display)
screen, a battery-powered remote control, and two head-
sets. The system is located in the headliner behind the
front row seat. Refer to your VES™ User’s Manual for
detailed operating instructions.
SATELLITE RADIO — IF EQUIPPED

ing technology to provide clear digital sound, coast to
coast. The subscription service provider is Sirius™ Satel-
lite Radio. This service offers over 100 channels of music,
sports, news, entertainment, and programming for chil-
dren, directly from its satellites and broadcasting studios.222 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury. WARNING!Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is250 STARTING AND OPERATING
