•The lap portion should be low on the hips and as snug
as possible.
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 miles (100 km), speeds
up to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits
of local traffic laws, contributes to a good break-in.
Avoid wide open throttle acceleration in low gear. The engine oil installed in the engine at the factory is a
high quality, energy conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and is not an indication of difficulty.
106 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
•Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
•If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
•The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.
108 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.Change Engine Oil
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Road conditions as well as your kind of driving affect the
interval at which your oil should be changed. Check the
following to determine if any apply to you:
•Day or night temperatures are below 32°F (0°C).
•Stop and go driving.
•Extensive engine idling.
•Driving in dusty conditions
•Short trips of less than 10 miles (16.2 km)
432 MAINTAINING YOUR VEHICLE
•More than 50% of your driving is at sustained high
speeds during hot weather, above 32°C (90°F)
•Trailer towing
•Heavy Loading
•Taxi, Police or delivery service (commercial service)
•Off-road or desert operation
•If equipped for and operating with E-85 (ethanol)
fuel.
NOTE: IfANY of these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedules section of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule Aof the Mainte-
nance Schedules section of this manual.
Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner, the crankcase inlet air cleaner and the
crankcase ventilation system. Make sure that these units
are clean at all times. This will tend to reduce to a
minimum the amount of abrasive material that may enter
the engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.

the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental ad-
ditives.
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 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 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. Mopar Engine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tensioner
Belt tension is controlled by means of an automatic
tensioner. No belt tension adjustments are required.
However, belt and belt tensioner condition should be
inspected at the specified intervals and replaced if re-
quired. See your authorized dealer for service.
At the mileage indicated in the maintenance schedule, all
belts and tensioner should be checked for condition.
Improper belt tension can cause belt slippage and failure.
Belts should be inspected for evidence of cuts, cracks,
glazing or frayed cords and replaced if there is indication
of damage which could result in belt failure. Low gen-
erator belt tension can cause battery failure.

Front Prop Shaft Lubrication — 2500/3500 (4X4)
Models
Lubricate the front driveshaft grease fitting at each oil
change listed in the appropriate Maintenance Schedule
for your vehicle (Schedule “A” and “B”). Use Mopar
type MS-6560 (lithium based grease), or equivalent.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, tailgate and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.

After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Mopar All
Weather Windshield Washer Solution, used with water as
directed on the container, aids cleaning action, reduces
the freezing point to avoid line clogging, and is not
harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to Exhaust Gas in the Safety Tips section of this
manual.

Clutch Linkage
If the clutch pedal linkage begins to squeak or grunt, the
clutch pedal pivot bushings should be lubricated. Refer
to Fluids, Lubricants and Genuine Parts for the correct
lubricant type.
Rear Axle And 4x4 Front Driving Axle Fluid Level
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type. For normal service, periodic fluid level
checks are not required. When the vehicle is serviced for
other reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is suspected
inspect the fluid level.
This inspection should be made with the vehicle in a level
position. The fluid level should be even with the bottom
of the fill hole for the Manufacturer’s C205F HD Front
Axles. The fluid level should be 5/8” (16 mm) below on
9 1/4” Manufacturer’s Rear Axles. For all 2500/3500 Model axles, the fluid level should be
1/4” ± 1/4” (6.4 mm ± 6.4 mm) below the fill hole on the
9.25” Front and 3/4”± 1/4” (19 mm ± 6.4 mm) on 10.5”
Rear axles. The 11.5” Rear Axle level should be 1/4” ±
1/4” (6.4 mm ± 6.4 mm) below the fill hole.
Drain and Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or to provide the correct viscosity grade, drain
and refill.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
