6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft.
lbs. (183 N·m) torque for 2500/3500 single rear wheel
(SRW) models and 145 ft. lbs. (197 N·m) for 3500 dual rear
wheel models. If in doubt about the correct tightness,
have them checked with a torque wrench by your dealer
or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided.
7. Install wheel center cap and remove wheel blocks. Do
not install chrome or aluminum wheel center caps on the
spare wheel. This may result in cap damage.8. Lower the jack to its fully closed position. If the jack
will not lower by turning the dial (thumb wheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.Hub Caps/Wheel Covers
The hub caps must be removed before raising the vehicle
off the ground.
For 2500/3500 single rear wheel (SRW) models, use the
blade on the end of the lug wrench to pry the hub cap off.
Insert the blade end into the pryoff notch and carefully
pop off the hub cap with a back and forth motion.
394 WHAT TO DO IN EMERGENCIES

These dual rear wheels should be tightened as follows:1. Tighten the wheel nuts in the numbered sequence to a
snug fit.
2. Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a
second time to verify that specific torque has been
achieved. Retighten to specifications at 100 miles (160
km) and after 500 miles (800 km).
It is recommended that wheel stud nuts be kept torqued
to specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation to allow the wheel nuts to become properly
set. All nuts should first be firmly seated against the

wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are
shown in the following chart.

To Stow The Flat Or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.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.

Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.
By simply driving your vehicle at highway speeds for as
little as 45 minutes you can remedy the condition in the
particulate filter system and allow your Cummins engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an ex-
tended period of time after the initial warning notifica-
tion, the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.
CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it’s capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horse-
power and torque output.
436 MAINTAINING YOUR VEHICLE

Selection Of Lubricant
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type. It is important that the transmis-
sion fluid be maintained at the prescribed level using the
recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants and Genuine Parts for correct
fluid type.
Automatic Transmission Fluid and Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center. It is important that the
transmission be adjusted periodically, the fluid main-
tained at the correct level, and that it be drained and
refilled as specified.
It is important that proper lubricant is used in the
transmission. Refer to 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(s) should be changed and the bands
adjusted (if equipped) as specified in the Maintenance
Schedule (Section 8). Vehicles with a 5.9L Diesel Engine,
having severe usage should follow Maintenance Sched-
ule “B” of the Maintenance Schedule (Section 8).
