CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
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.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.

FUSES
WARNING!
•When replacing a blown fuse, always use an ap-
propriate replacement fuse with the same amp
rating as the original fuse. Never replace a fuse
with another fuse of higher amp rating. Never
replace a blown fuse with metal wires or any other
material. Failure to use proper fuses may result in
serious personal injury, fire and/or property dam-
age.
• Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.
(Continued)
WARNING! (Continued)
•If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, gearbox system) or steering system
blows, contact an authorized dealer.

•2500 – 3500 Models
• Under no circumstances should oil change intervals
exceed 8,000 miles (13,000 km) or twelve months on
2500 – 3500 trucks, whichever comes first.
• Severe Duty All Models
• Change Engine Oil at 4000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environ-
ment. This type of vehicle use is considered Severe
Duty Once A Month Or Before A Long Trip:
•
Check engine oil level
• Check windshield washer fluid level
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering (2500/3500 Models
Only) and automatic transmission (six-speed only) as
needed
• Check function of all interior and exterior lights
