4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered.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 single rear wheel (SRW) models
and 145 ft. lbs. (197 N´m) for 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 (if equipped) and remove
wheel blocks. Do not install chrome or aluminum wheel
center caps on the spare wheel. This may result in cap
damage.
384 WHAT TO DO IN EMERGENCIES

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 Nut Torque
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 (If Equipped)
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (If Equipped).
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.

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.
The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.
424 MAINTAINING YOUR VEHICLE

Automatic Transmission (Gas Engine Only)
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.
Fluid Level Check ± 545RFE Transmission
Check the fluid level while the transmission is at normal
operating temperature 180É F (82É C). This occurs after at
least 15 mi (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
Procedure For Checking Fluid Level
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply parking brake.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).
446 MAINTAINING YOUR VEHICLE

Automatic Transmission Fluid and Filter Change
Follow the Maintenance Schedule for recommended
transmission fluid and filter change intervals.
NOTE:If the transmission is disassembled for any
reason, the fluid and filter should be changed.
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.
Automatic Transmission (Diesel Engine Only)
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 se-
rious damage to the transmission. Refer to Fluids,
Lubricants and Genuine Parts for correct fluid type.
Fluid Level Check ± AS68RC Transmission
Check the fluid level while the transmission is at normal
operating temperature 167É F (76É C). This occurs after at
least 15 mi (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
