5. Remove the wheel nuts and pull the wheel off. On
single rear-wheel (SRW) trucks, install the spare wheel
and wheel nuts with the cone shaped end of the wheel
nuts toward the wheel. On 3500 dual rear-wheel models
(DRW) the wheel nuts are a two-piece assembly with a
flat face. Lightly tighten the wheel nuts. To avoid the risk
of forcing the vehicle off the jack, do not fully tighten the
wheel nuts until the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the wheel
nuts using a crisscross pattern. The correct wheel nut
tightness is 130 ft lbs (177 N·m) torque (1500 Series), 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 tight-
ness, have them checked with a torque wrench by your
authorized 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 the wheel center cap and remove the 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 bottle
jack will not lower by turning the dial (thumbwheel) 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.

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 “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the EVIC telltale display area.
Refer to “Electronic Vehicle Information Center (EVIC) in
“Understanding Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly and press

the SELECT button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
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.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.
520 MAINTAINING YOUR VEHICLE

4. 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 isnot readyand you should
notproceed 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
isreadyand you can proceed to the I/M station.
If your OBD II system isnot 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 IIsystem 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 PARTS
Use of genuine MOPARparts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPARparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.

522 MAINTAINING YOUR VEHICLE

Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
NOTE:For 2500/3500 trucks with a 5.7L engine oper-
ating under a gross combined weight rating of 14,000 lbs
(6 350 kg) or greater, SAE 5W-30 engine oil is recom-
mended for all operating temperatures.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high-
quality filters should be used to assure most efficient
service. MOPARengine oil filters are a high-quality oil
filter and are recommended.7
