2009 DODGE RAM 3500 DIESEL battery

5. Approximately 15 seconds later, one of two things will
happen:a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.
REPLACEMENT PARTSUse of genuine MOPAR
parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.DEALER SERVICEYour authorized dealer has the qualified service person-
nel, special tools and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for

Engine Air Cleaner FilterRefer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.Engine Air Cleaner Filter SelectionThe quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should beused to assure most efficient service. MOPAR
engine air
cleaner filters are a high quality filter and are
recommended.
Maintenance-Free BatteryThe top of the maintenance-free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.
WARNING!
•
Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.

WARNING! (Continued)
•
Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
•
Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
CAUTION!
•
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and (-) negative and are identified on the
battery case.
•
If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage.
Air Conditioner MaintenanceFor best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should

compartment near the battery. This center contains car-
tridge fuses and mini fuses. A description of each fuse
and component may be stamped on the inside cover,
otherwise the cavity number of each fuse is stamped on
the inside cover that corresponds to the following chart.

VEHICLE STORAGEIf 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:•
Disconnect the Ignition-Off Draw (IOD) fuse located in
the Integrated Power Module, located in the engine
compartment. The IOD cavity includes a snap-in re-
tainer that allows the fuse to be disconnected without
removing it from the fuse block.
•
The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•
As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
•
Any 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.
•
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
instrument cluster in the odometer window will dis-
play NO FUSE.”

At Each Stop for Fuel•
Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•
Check the windshield washer solvent and add if
required.
Once a Month
•
Check tire pressure and look for unusual wear or
damage.
•
Inspect the battery, clean and tighten the terminals as
required.
•
Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
•
Check all lights and other electrical items for correct
operation.
At Each Oil Change
•
Change the engine oil filter.
•
Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.Required Maintenance IntervalsRefer to the Maintenance Schedules on the following
