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.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any of these conditions
are present, clean the wiper blades or replace as neces-
sary.
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 ra-
diator antifreeze). When refilling the washer fluid reser-
voir, 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
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.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.

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 dam-
age. 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
