Fuel/Water Separator Filter

Within 10 minutes of vehicle shutdown, turn the
filter drain valve (located on the bottom of the filter
housing) counterclockwise to drain fuel/water;
allow the accumulated water to drain. Leave the
drain valve open until all water and contaminants
have been removed. When clear fuel is visible,
close the drain valve by turning it clockwise.
Upon proper draining of the water from fuel filter
assembly, the Water In Fuel Indicator Light will
remain illuminated for approximately 10 seconds.
If the water was drained while the engine was
running, the Water In Fuel Indicator Light may
remain on for approximately three minutes.
NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi -
ronment. Contact an authorized dealer, service
station, or government agency for advice on recy -
cling programs and for where used fluids and
filters can be properly disposed of in your area.
If more than two ounces or 60 ml of fuel have been
drained, follow the directions for Priming If The
Engine Has Run Out Of Fuel Ú page 370.

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 concerned
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
accumulations 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.
CAUTION!
The cabin air filter is identified with an arrow to
indicate airflow direction through the filter.
Failure to properly install the filter will result in
the need to replace it more often.

and carpeting.
Seat Belt Maintenance
If the belts need cleaning, use a mild soap solution
or lukewarm water. Do not remove the belts from
the vehicle to wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or
if the buckles do not work properly.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable, and
if used in closed areas they may cause
respiratory harm.
CAUTION!
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This will
weaken the fabric. Sun damage can also
weaken the fabric
WARNING!
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision,
or if you have questions regarding seat belt or
retractor conditions, take your vehicle to an
authorized FCA dealer or authorized FCA
Certified Collision Care Program facility for
inspection.
