Climate Control Functions
A/C (Air Conditioning) 
The Air Conditioning (A/C) button allows the
operator  to  manually  activate  or  deactivate
the  air  conditioning  system.  When  the  air
conditioning system is turned on, cool dehu-
midified air will flow through the outlets into
the cabin. For improved fuel economy, press
the A/C button to turn off the air conditioning
and  manually  adjust  the  blower  and  airflow
mode settings. Also, make sure to select only
Panel, Bi-Level, or Floor modes.
NOTE:
For Manual Climate Controls, if the system
is  in  Mix,  Floor  or  Defrost  Mode,  the  A/C
can be turned off, but the A/C system shall
remain  active  to  prevent  fogging  of  the
windows.
If fog or mist appears on the windshield or
side  glass,  select  Defrost  mode,  and
increase blower speed if needed.
If  your  air  conditioning  performance
seems  lower  than  expected,  check  the
front of the A/C condenser (located in front
of the radiator), for an accumulation of dirt or insects. Clean with a gentle water spray
from the front of the radiator and through
the condenser.
MAX A/C
MAX  A/C  sets  the  control  for  maximum
cooling performance.
Press and release to toggle between MAX A/C
and the prior settings. The button illuminates
when MAX A/C is on.
In MAX A/C, the blower level and mode position
can  be  adjusted  to  desired  user  settings.
Pressing other settings will cause the MAX A/C
operation to switch to the selected setting and
MAX A/C to exit.
Recirculation
In  cold  weather,  use  of  Recirculation  mode
may  lead  to  excessive  window  fogging.  The
Recirculation  feature  may  be  unavailable
(button  on  the  touchscreen  greyed  out)  if
conditions exist that could create fogging on
the inside of the windshield.
Automatic Temperature Control (ATC) — 
If Equipped  
Automatic Operation
1. Push the AUTO button on the faceplate, or  the  AUTO  button  on  the  touchscreen
on  the  Automatic  Temperature  Control
(ATC) Panel.
2. Next,  adjust  the  temperature  that  you would  like  the  system  to  maintain  by
adjusting  the  driver  and  passenger
temperature  control  buttons.  Once  the
desired  temperature  is  displayed,  the
system  will  achieve  and  automatically
maintain that comfort level.
3. When  the  system  is  set  up  for  your comfort  level,  it  is  not  necessary  to
change  the settings. You will  experience
the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
It  is  not  necessary  to  move  the  tempera-
ture  settings  for  cold or hot vehicles.  The
system automatically adjusts the tempera-
ture,  mode,  and  blower  speed  to  provide
comfort as quickly as possible.

The temperature can be displayed in U.S.
or  Metric  units  by  selecting  the  U.S./
Metric  customer-programmable  feature.
Refer  to  the  “Uconnect  Settings”  in
“Multimedia”  in  the  Owner’s  Manual  for
further information.
To provide you with maximum comfort in the
Automatic  mode  during  cold  start-ups,  the
blower  fan  will  remain  on  low  until  the
engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This  system  offers  a  full  complement  of
manual override features. The AUTO symbol
in  the  front  ATC  display  will  be  turned  off
when the system is being used in the manual
mode.
Operating Tips 
Summer Operation
The  engine  cooling  system  must  be
protected  with  a  high-quality  antifreeze
coolant  to  provide  proper  corrosion  protec -
tion  and  to  protect  against  engine  over -
heating.  OAT  coolant  (conforming  to
MS.90032) is recommended.
Winter Operation
To  ensure  the  best  possible  heater  and
defroster performance, make sure the engine
cooling  system  is  functioning  properly  and
the  proper  amount,  type,  and  concentration
of coolant is used. Use of the Air Recircula -
tion  mode  during  Winter  months  is  not
recommended, because it may cause window
fogging.
Vacation/Storage  
Before you store your vehicle,  or keep  it  out
of  service  (i.e.,  vacation)  for  two  weeks  or
more, run the air conditioning system at idle
for  about  five  minutes,  in  fresh  air  with  the
blower  setting  on  high.  This  will  ensure
adequate system lubrication to minimize the
possibility  of  compressor  damage  when  the
system is started again.
Window Fogging 
Vehicle windows tend to fog on the inside in
mild,  rainy,  and/or  humid  weather.  To  clear
the windows, select Defrost or Mix mode and
increase the front  blower  speed.  Do  not  use
the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make  sure the  air  intake, located  directly in
front  of  the  windshield,  is  free  of  obstruc -
tions, such as leaves. Leaves collected in the
air  intake  may  reduce  airflow,  and  if  they
enter the plenum, they could plug the water
drains. In Winter  months, make sure the air
intake is clear of ice, slush, and snow.
 CAUTION!
Failure to  follow  these cautions  can  cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners  on  the  interior  surface  of  the
window.  Use  a  soft  cloth  and  a  mild
washing  solution,  wiping  parallel  to  the
heating elements. Labels  can be peeled
off after soaking with warm water.
Do not use scrapers, sharp  instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

Gear Shift Indicator (GSI) — If Equipped
The  Gear  Shift  Indicator  (GSI)  system  is
enabled  on  vehicles  when  automatic  trans-
mission  is  in  manual  shift  mode.  The  GSI
provides  the  driver  with  a  visual  indication
when the recommended gear shift point has
been  reached.  This  indication  notifies  the
driver that changing gears will allow a reduc -
tion in fuel consumption. When the up shift
indicator is shown on the instrument cluster
display,  the  GSI  is  advising  the  driver  to
engage  a  higher  gear.  When  the  down  shift
indicator is shown on the display, the GSI is
advising the driver to engage a lower gear.
The GSI remains illuminated until the driver
changes  gear,  or  the  driving  conditions
return to a situation where changing gears is
not required to improve fuel consumption.

Diesel Particulate Filter (DPF) Messages 
This engine meets all required diesel engine
emissions standards. To achieve these emis -
sions  standards,  your  vehicle  is  equipped
with  a  state-of-the-art  engine  and  exhaust
system.  These  systems  are  seamlessly  inte -
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages  engine  combustion  to  allow  the
exhaust  system’s  catalyst  to  trap  and  burn
Particulate  Matter  (PM)  pollutants,  with  no
input or interaction on your part.
 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.
 CAUTION!
Always drive  at  a  speed appropriate  to the
traffic  conditions,  the  weather  and  traffic
regulations.  The  engine  may  be  switched
off even if the warning light is on: repeated
interruptions  of  the  regeneration  process
could  cause  an  early  deterioration  of
engine  oil.  For  this  reason  it  is  always
advisable  to  wait  for  the  symbol  to  go  off
before turning off the engine, following the
instructions  above.  Do  not  complete  the
DPF regeneration process when the vehicle
is stopped.
