towing DODGE RAM 2500 DIESEL 2004 3.G Owner's Guide

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.
314 WHAT TO DO IN EMERGENCIES

TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer's instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
the main structural members of the vehicleÐnot to
bumpers or associated brackets. State and local laws
applying to vehicles under tow must be observed.
4-Wheel- Drive Vehicles
CAUTION!
To avoid damage to the transfer case while towing,
always use one of the following methods.
The manufacturer recommends towing with all wheels
off the ground. Acceptable methods are to tow vehicle on
a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
2±Wheel- Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in Neutral and the ignition key in the OFF
position along with the front wheels raised and the rear
wheels on the ground. Speed must not exceed 30 mph (50
km/h) and distance must not exceed 15 miles (25 km).
If the vehicle is to be towed more than 15 miles (25 km)
the vehicle must be towed with the rear wheels raised
and the front wheels on the ground. It may also be towed
on a flatbed or with the front wheels raised and the rear
wheels on a dolly.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CARB emission control vehicles are equipped with a
sophisticated onboard diagnostic system called OBDII.
This system monitors the performance of the emissions,
engine, and automatic transmission control systems.
When these systems are operating properly, your vehicle
will provide excellent performance and fuel economy, as
well as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

²Driving in dusty conditions.
²Frequent trailer towing.
²Taxi, police, or delivery service (commercial service).
²Off-road or desert operation.
²Extensive operation at high engine speeds (greater
than 2900 rpm) and loads (greater than 70% throttle).
IfANYof these apply to you, then change your engine oil
at every interval shown in schedule9B9of the9Mainte-
nance Schedules9section of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule9A9of the9Mainte-
nance Schedules9section of this manual.
NOTE:Most vehicles are operated under the conditions
listed for Schedule9B.9
Engine Oil Selection
1. Engine Oil Quality
Use only oils conforming to API
Service CI-4. A sulfated ash limit
is specified for lubrication oil used
in Cummins engines. Oils with a
high ash content may produce de-
posits on valves that can progress
to guttering and valve burning. A
maximum sulfated ash content of
1.85 mass % is recommended for
all oil used in the engine.
2. Engine Oil Viscosity (SAE Grade)
The proper SAE viscosity of engine oil for the expected
ambient temperature range should be selected, as indi-
cated in the following chart:
MAINTAINING YOUR VEHICLE 327
7

It is important that proper lubricant is used in the
transmission. Refer to Recommended Fluids, Lubricants
and Genuine Parts for the correct lubricant type. A band
adjustment and filter change should be made at the time
of the oil change.
The fluid and filter should be changed and the bands
adjusted as specified in the Maintenance Schedule (Sec-
tion 8). Vehicles having severe usage should follow
Maintenance Schedule ªBº of the Maintenance Schedule
(Section 8).
Severe usage consists of:
²Off-the-highway operation;
²Trailer towing;
²Snow plow operation;
²Prolonged operation with heavy loading, especially in
hot weather.NOTE:If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
ªpurgeº excess grease and the bearing housing will look
slightly wet. This is normal.
²Periodic inspection for excess play is recommended.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typein this section (Section 8) must be done at the times
or mileages specified to assure the continued proper
functioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions such as dusty
areas and very short trip driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULES Ð 24±VALVE
