flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, for further war-
ranty information.
•
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.
CAUTION!
Do not use chemical flushes in your air condition-
ing system as the chemicals can damage your air
conditioning components. Such damage is not cov-
ered by the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance
with a low global-warming potential. The manufacturer
recommends that air conditioning service be performed
by an authorized dealer using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
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 assure 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 latch-
ing components to ensure proper function. When per-
forming
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 Fall and Spring. Apply a small

amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.
Wiper Blades
Clean the rubber edges of the wiper blades, the wind-
shield, and rear window periodically with a sponge or
soft cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt, waxes, or road film, and
help reduce streaking and smearing.
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 or rear window.
Avoid using the wiper blades to remove frost or ice from
the windshield or rear window. Make sure that they are
not frozen to the glass before turning them on to avoid
damaging the blade. Keep the wiper blade 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 condi-
tions are present, clean the wiper blades or replace as
necessary.
Blade Lifting
If it is necessary to lift the blade from the windshield (In
the event of snow or blade replacement) Proceed as
directed:
1. Rotate the end of the multifunction lever to the OFF
position.
2. Turn the ignition to the MAR-ON position then to
STOP.
3. After turning the ignition to the STOP, within two
minutes move the right stalk upward, into the un-
stable (“anti-panic”) position, for at least half of a

second. The windshield wiper then executes part of a
stroke; at each command, approximately 1/3 of a
normal wiper stroke is triggered.
NOTE:
The previous operation can be repeated up to
three times. In order to move the blades to the most
suitable position.
4. Lift the blade from the windshield and proceed with
the required operation.
5. Carefully lower the blade, bringing it back in contact
with the windshield.
6. Bring the blade to the initial rest position, turning the
ignition to MAR-ON.
NOTE:
Do not operate the screen wiper with the blades
lifted from the windshield.
Front Wiper Blade Removal/Installation
1. Lift the front wiper arm upward to raise the wiper
blade off of the windshield.
2. Push the release button on the arm of the wiper
blade.
3. Push the wiper blade up and remove it.
4. Install the wiper blade and firmly push the wiper
blade until it snaps into place.

If there is not a jet of fluid, first check that there is fluid
in
the
washer
reservoir.
Refer
to
“Adding
Washer
Solvent” in this chapter for further information.
Then check that the nozzle holes are not clogged; use a
suitable tool such as a needle to unblock them if
necessary.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine ex-
haust 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 exhaust system and adjacent body areas for
broken, damaged, 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.
WARNING!
•
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you unconscious
and can eventually poison you. To avoid breath-
ing CO, refer to “Safety Tips” in “Safety” for
further information.
•
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.
CAUTION!
•
The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions con-
trol device and may seriously reduce engine per-
formance and cause serious damage to the engine.
•
Damage to the catalytic converter can result if
your
vehicle
is
not
kept
in
proper
operating
