2004 DODGE RAM 2500 DIESEL warning

CAUTION!
Use the Jump Start Procedure only when the charge
indicator (if equipped) in both batteries is dark in
the center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If charge indicator (if equipped) has a green
dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
1. Attach one jumper cable to the positive terminal of
booster battery and the other end of the same cable to the
positive terminal of the discharged battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.

2. Connect one end of the other jumper cable to negative
(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.
WARNING!
²Do not connect the cable to the negative post of
the discharge battery. The resulting electrical
spark could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump start.
3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do not
lean over the battery when making connection. The
negative connection must provide good electrical con-
ductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start,
cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine ground.
b. Disconnect the negative cable at the negative post
on booster battery.
c. Disconnect the cable from the positive post of both
batteries.
312 WHAT TO DO IN EMERGENCIES

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,
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
not freeing the vehicle, may lead to transmission over-
heating and failure. Allow the engine to idle with the
WHAT TO DO IN EMERGENCIES 313

transmission selector in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a stuck
vehicle.
EMERGENCY TOW HOOKS Ð IF EQUIPPED
Your vehicle may be equipped with emergency tow
hooks.
WARNING!
Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury or
death.
WARNING!
Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.

CAUTION!
To maintain your vehicle safely follow these guide-
lines:
²Watch your vehicle's mileage and check yourMainte-
nance Schedulesregularly for required servicing. Ex-
cessive wear or damage to certain vehicle components
can result if required services are not performed.
²If you have your vehicle undercoated, inspect for
undercoating material on the propeller shafts. Such
material could cause the shafts to become unbalanced
and result in drivetrain vibrations. Remove any under-
coating with solvent.
²If you have your vehicle undercoated, make sure no
undercoating material is sprayed on the exhaust sys-
tem or components of the seat belt system.
NOTE:It is not possible for the manufacturer and

intake piping or turbocharger inlet in an attempt to
start the vehicle.

²Do 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.
²If an engine has been operating and the coolant is hot,
allow the engine to cool before you slowly loosen the
filler cap and relieve the pressure from the cooling
system.
²To avoid burns, remember that the engine components
will stay hot after the engine is shut off.
²Do not use gasoline or other flammable materials to
clean parts. Always use approved cleaning solvents.
²Relieve all pressure in the fuel, oil and cooling systems
before any lines, fittings or related items are removed
or disconnected. Be alert for possible pressure when
disconnecting any device from a system that utilizespressure. Do not check for pressure leaks with your
hand. High pressure oil or fuel can cause personal
injury.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
