WARNING!(Continued)
•Failure to properly inspect and maintain your vehicle
could result in a component malfunction and effect
vehicle handling and performance. This could cause
an accident.
Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.

Checking Oil Level — Gas Engine
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 will cause oil aeration or
loss of oil pressure. This could damage your engine.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or towel and wipe
the wiper blades clean. This will help blade performance.To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the con-
tainer, aids cleaning action, reduces the freezing point to
avoid line clogging, and is not harmful to paint or trim.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.

WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with
large amounts of water. Refer to “Jump Starting
Procedure” in “In Case Of Emergency” for further
information.
• Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Do not use a booster
battery or any other booster source with an output
greater than 12 Volts. Do not allow cable clamps to
touch each other.
• Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Wash hands after
handling.
CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
(Continued)
CAUTION! (Continued)
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
• If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a
“fast charger” to provide starting voltage.

concern for fleet customers. 2500 – 3500 Models Only
NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km), twelve months or
