GETTING TO KNOW YOUR VEHICLE67
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized
dealer to service your cabin air filter, and to
have it replaced when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control
system may automatically adjust airflow to
maintain cabin comfort. Customer settings will
be maintained upon return to an engine running
condition.
Windshield Wiper De-Icer — If Equipped
The windshield wiper de-icer is a heating
element located at the base of the windshield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The wiper de-icer activates automatically
during a cold weather manual start with full
defrost, and when the ambient temperature
is below 33°F (0.6°C) .
Activation By Rear Defrost
The wiper de-icer activates automatically
when the Rear Defrost is operating and the
ambient temperature is below 33°F (0.6°C) .
Activation By Remote Start Operation
When the Remote Start is activated and the
outside ambient temperature is less than
33°F (0.6°C) the windshield wiper de-icer is
activated. Upon exiting Remote Start, the
climate control functions will resume their
previous operation except, if the de-icer is
active, the de-icer timer and operation will
continue.

DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component 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 harmless nitrogen and water vapor.
Refer to Engine Fluids And Lubricants
Úpage 475 for further information.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air
conditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
Refrigerant Recovery And Recycling —
R–1234yf
R–1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. It is recommended
that air conditioning service be performed by an
authorized dealer using recovery and recycling
equipment.
NOTE:
Use only FCA approved A/C system PAG
compressor oil, and refrigerants.
Cabin Filter Replacement (A/C Air Filter)
For the proper maintenance intervals
Úpage 395.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by FCA for your air condi -
tioning system. Some unapproved
refrigerants are 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 warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.
WARNING!
Do not remove the cabin air filter while the
vehicle is running, or while the ignition is in
the ACC or ON/RUN mode. With the cabin air
filter removed and the blower operating, the
blower can contact hands and may propel dirt
and debris into your eyes, resulting in
personal injury.

When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal. This
is not a reason to replace the belt. However,
cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib
must be replaced. Also have the belt replaced if
it has excessive wear, frayed cords or severe
glazing.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.

WARNING!
Do not attempt to inspect an accessory
drive belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could
be injured by the moving fan blades.
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 compe -
tent mechanic.
