2004 DODGE RAM 1500 GAS towing

Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING
You should not try to start your vehicle by pushing or
towing. Vehicles equipped with an automatic transmis-
sion cannot be started this way and pushing or towing a
vehicle equipped with a manual transmission may over-
heat and damage the catalytic converter. Also, there is a
greater risk of an accident when a vehicle is being pushed
or towed. 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, so follow this
procedure carefully.
312 WHAT TO DO IN EMERGENCIES

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.
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).

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. 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 emis-
sions 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.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
324 MAINTAINING YOUR VEHICLE

Change Engine Oil
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Road conditions as well as your kind of driving affect the
interval at which your oil should be changed. Check the
following to determine if any apply to you:
²Day or night temperatures are below 32ÉF (0ÉC).
²Stop and go driving.
²Extensive engine idling.
²Driving in dusty conditions
²Short trips of less than 10 miles (16.2 km)
²More than 50% of your driving is at sustained high
speeds during hot weather, above 32ÉC (90ÉF)
²Trailer towing
²Heavy Loading
²Taxi, Police or delivery service (commercial service)
²Off-road or desert operation
²If equipped for and operating with E-85 (ethanol)
fuel.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule ªBº of the
9Maintenance 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.
330 MAINTAINING YOUR VEHICLE

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer's specifications, should be ob-
tained immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Emission-Related Components
Positive Crankcase (PCV) Valve
Proper operation of the crankcase ventilation system
requires that the PCV valve be free of sticking or plug-
ging from deposits. Deposits can accumulate in the PCV
valve and passages with increasing mileage. Have the
PCV valve, hoses, and passages checked for proper
operation at the intervals specified. If the valve is

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.
