Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km) or 350 hours ofengine 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. This type of vehicle use is consid -
ered Severe Duty.
WARNING!
• You can be badly injured working on or around a motor vehicle. Do only service work for which you have the
knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
• 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.

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 main-
tain 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.
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.
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 solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling will cause oil aeration or loss
of oil pressure. This could damage your engine.
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.

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.
Pressure Washing
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 contain 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 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 corro -
sion.
• 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.
CAUTION!
Cleaning the engine compartment with a high pressure
washer is not recommended. Precautions have been
taken to safeguard all parts and connections however,
the pressures generated by these machines is such that
complete protection against water ingress cannot be
guaranteed.

Engine Oil — Gas Engine
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance. Refer
to the “Maintenance Plan” for further information.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.
Gasoline Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only recom -
mends engine oils that are API Certified and meet the
requirements of FCA Material Standard MS-6395.
WARNING!
You can be badly injured working on or around a motor
vehicle. Only do service work for which you have the
knowledge and the proper equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended engine
oil viscosity for your engine. For information on engine oil
filler cap location, refer to the “Engine Compartment” illus -
tration in this section. Lubricants which do not have both the engine oil certifica
-
tion mark and the correct SAE viscosity grade number
should not be used.
