2007 DODGE RAM 2500 DIESEL charging

Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the switch) is rotated to the
upward detent position, or if equipped, when the UN-
LOCK button is pressed on the key fob. When a door is open and the interior lights are on, rotating the dimmer
control all the way down to the OFF detent will cause all
the interior lights to go out. This is also known as the
 Party
mode because it allows the doors to stay open for
extended periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are ON you can
supplement the brightness of the odometer, trip odom-
eter, radio and overhead console by rotating the control
up until you hear a click. This feature is termed the
“Parade” mode and is useful when headlights are re-
quired during the day.
Club Cab/Quad Cab models may have an optional
switched dome lamp that may be operated by pressing
the lens.

NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.
GARAGE DOOR OPENER — IF EQUIPPED
The HomeLink Universal Transceiver replaces up to
three remote controls (hand held transmitters) that operate
devices such as garage door openers, motorized gates, or
home lighting. It triggers these devices at the push of a
button. The Universal Transceiver operates off your vehi-
cle’s battery and charging system; no batteries are needed.

JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-
ing with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
Your vehicle is equipped with two 12–volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle’s engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting
out the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
With Portable Starting Unit
There are many types of these units available. Follow the
manufacturer’s instructions for necessary precautions
and operation.
CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12 Volts D.C. or damage to
battery, starter motor, alternator, or electrical system
may occur.
FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE
(automatic transmissions) and between 1st and RE-
VERSE (manual transmissions), while applying slight
pressure to the accelerator.
In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine is most effective. Racing the
engine or spinning the wheels, due to the frustration of
370 WHAT TO DO IN EMERGENCIES

WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.
NOTE: A maximum blend of 5% biodiesel may be used
with your Cummins Diesel equipped Dodge Ram Truck NOTE:
As sufficient testing as not been completed,
ethanol blends are not recommended or approved for use
with your Cummins Diesel equipped Dodge Ram Truck.
NOTE: In addition, commercially available fuel addi-
tives are not necessary for the proper operation of your
Cummins Diesel equipped Dodge Ram Truck.
Maintenance Free Batteries
The top of the maintenance free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE: Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
