key DODGE RAM 2500 DIESEL 2008 3.G Workshop Manual

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 mi (25
km).
CAUTION!
Towing faster than 30 mph (50 km/h) or for more than
15 mi (25 km) can cause severe damage to the
transmission.If the vehicle is to be towed faster than 30 mph (50 km/h)
or more than 15 mi (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.
WHAT TO DO IN EMERGENCIES 403

Draining Fuel/Water Separator Filter (6.7L Diesel
Engine)
CAUTION!
Do not drain the fuel/water separator filter when the
engine is running.
CAUTION!
Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility that debris could be
introduced into the fuel filter during this action. It is
best to install the filter dry and allow the in-tank lift
pump to prime the fuel system.
NOTE:The fuel filter and water separator assembly is
located on the driver's side of the engine. The best access
to the water drain valve is through the driver's side
wheel well.
NOTE:If water is detected in the water separator while
the engine is running or while the key is in the on
position, the WATER IN FUEL LIGHT will illuminate
and an audible chime will be heard five times. At this
point you should stop the engine and drain the water
from the separator.
422 MAINTAINING YOUR VEHICLE

If the WATER IN FUEL LIGHT comes on and a single
chime is heard while you are driving, or with the key in
the ON position, there may be a problem with your water
separator wiring or sensor. See your authorized dealer
for service.
Upon proper draining of the water from the fuel filter, the
WATER IN FUEL LIGHT will remain illuminated for
approximately 10 seconds. If the water was drained
while the engine was running, the water in fuel light may
remain on for approximately three minutes.
NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact your local authorized dealer, service station, or
government agency for advice on recycling programs
and for where used fluids and filters can be properly
disposed of in your area.Drain a small amount from the fuel/water separator
filter monthly or when the WATER IN FUEL LIGHT is
on. Turn the drain valve located on the bottom of the
filter counterclockwise and allow any accumulated water
to drain into an approved container. Leave the drain
valve open until all water and contaminants have been
removed. Close the drain valve by turning it clockwise
when clean fuel is visible.
NOTE:The Fuel / Water separator drain valve is
located on the bottom of the fuel filter housing.
If more than a couple ounces of fuel has been drained,
follow the directions below for ªPriming if the engine has
run out of fuel.º

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.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank, approxi-
mately 5 to 10 gallons (19L to 38L).
2. Crank the engine for one to two seconds. If the engine
does not start, then release the key or starter button back
to the RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.3. Start the engine using the normal starting procedure.
4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
CAUTION!
Diesel fuel will damage black top paving surfaces.
Drain the filter into an appropriate container.
424 MAINTAINING YOUR VEHICLE

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle's battery:
²Disconnect the Ignition-Off Draw fuse (IOD) fuse
located in the Integrated Power Module, located in the
engine compartment. The IOD cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
²The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
²As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
²Any time you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutesin the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated; the gauges in the instrument cluster will do
a full sweep when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:When the vehicle is shipped from the factory,
the IOD fuse is in the up, or extracted position. If the
radio, interior lamps, keyless entry, or other features do
not work with the key OFF, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the instru-
ment cluster in the odometer window will display9NO
