SERVICING AND MAINTENANCE
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key com-
ponent of selective catalytic reduction (SCR) systems,
which help diesel vehicles meet stringent emission
regulations. DEF is a liquid reducing agent that reacts
with engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx) into harm-
less nitrogen and water vapor.
Refer to "Fluids And Lubricants" in "Technical Specifica-
tion" for further information.
You can receive assistance in locating DEF in the United
States by calling 866-RAM-INFO (866-726-4636). In
Canada call 1–800–465–2001 (English) or 1–800–
387–9983 (French)
You can receive assistance in locating DEF by contact-
ing an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as Mopar® Spray White Lube to ensure quiet,
easy operation and to protect against rust and wear.
Prior to the application of any lubricant, the parts con-
cerned 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 components to ensure 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 Autumn 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 depending on
geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering,
marks, water lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or replace as
necessary.
The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the
following points:
•
Wear or uneven edges
•
Foreign material
•
Hardening or cracking
•
Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass
may be damaged.
1. Lift the wiper arm to raise the wiper blade off of the
glass, until the wiper arm is in the full up position.
