symbol in the rear display. The rear temperature
and air source are controlled from the front
Uconnect system.
Rear second row occupants can only adjust the
rear ATC control when the Rear Temperature
Lock button is turned off.
The rear ATC is located in the headliner, near
the center of the vehicle.
Press the Rear Temperature Lock button on
the Uconnect touchscreen. This turns off the
Rear Temperature Lock icon in the rear
temperature knob.
Rotate the Rear Blower, Rear Temperature
and the Rear Mode Control knobs to suit your
comfort needs.
ATC is selected by adjusting the rear blower
knob counterclockwise to AUTO.
Once the desired temperature is displayed, the
ATC System will automatically achieve and
maintain that comfort level. 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.
CLIMATE CONTROL FUNCTIONS
A/C (Air Conditioning)
The A/C (Air Conditioning) button allows the
operator to manually activate or deactivate the
air conditioning system. When the air
conditioning system is turned on, cool
dehumidified 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 A/C 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.

20_WD_OM_EN_USC_t.book Page 68

70GETTING TO KNOW YOUR VEHICLE
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 (A/C) 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
Interior fogging on the windshield can be quickly
removed by turning the mode selector to
Defrost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide
sufficient heating. If side window fogging
becomes objectionable, increase blower speed
to improve airflow and clearing of the side
windows. Vehicle windows tend to fog on the
inside in mild but rainy or humid weather.
NOTE:
Recirculate without A/C should not be used
for long periods, as fogging may occur.
Automatic Temperature Controls (ATC) will
automatically adjust the climate control
settings to reduce or eliminate window
fogging on the front windshield. When this
occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions,
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.
A/C Air Filter
The climate control system filters outside air
containing dust, pollen and some odors. Strong
odors cannot be totally filtered out. Refer to
“Dealer Service” in “Servicing And
Maintenance” for filter replacement
instructions.
Operating Tips Chart
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 interior
surface of the window.
Keep all objects a safe distance from the
window.
CAUTION!
Interior air enters the Rear Automatic
Temperature Control System through an
intake grille, located in the right side trim
panel behind the third row seats. The heater
outlets are located in the right side trim
panel, just behind the sliding door. Do not
block or place objects directly in front of the
inlet grille or heater outlets. The electrical
system cold overload causing damage to the
blower motor.

112GETTING TO KNOW YOUR INSTRUMENT PANEL
If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come
on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as
a bulb check. If the light does not come on
during starting, have the system checked by an
authorized dealer.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too
high, this indicator will illuminate and
a single chime will sound. If the temperature
reaches the upper limit, a continuous chime will
sound for four minutes or until the engine is
able to cool, whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning
(A/C) system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the
vehicle. If the temperature reading does not
return to normal, turn the engine off
immediately and call for service. Refer to “If Your Engine Overheats” in “In Case
Of Emergency” for further information.
Hood Open Warning Light
This warning light will illuminate when
the hood is left open and not fully
closed.
NOTE:
If the vehicle is moving, there will also be a
single chime.
Liftgate Open Warning Light
This warning light will illuminate when
the liftgate is open.
NOTE:
If the vehicle is moving, there will also be a
single chime.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on. Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to
indicate the engine oil temperature is
high. If the light turns on while driving,
stop the vehicle and shut off the

20_WD_OM_EN_USC_t.book Page 112

252STARTING AND OPERATING
Automatic Transmission
Select the DRIVE (D) range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions, will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
engine idle speed. Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
SNOW PLOW
Snow plows, winches, and other aftermarket
equipment should
not be added to the front end
of your vehicle. The airbag crash sensors may
be affected by the change in the front end
structure. The airbags could deploy
unexpectedly or could fail to deploy during a
collision.
WARNING!
Do not add a snow plow, winches, or any
other aftermarket equipment to the front of
your vehicle. This could adversely affect the
functioning of the airbag system and you
could be injured.

324SERVICING AND MAINTENANCE
The radiator normally remains completely full,
so there is no need to remove the radiator/
coolant pressure cap unless checking for
engine coolant (antifreeze) freeze point or
replacing coolant. Advise your service attendant
of this. As long as the engine operating
temperature is satisfactory, the coolant bottle
need only be checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of FCA
Material Standard MS.90032 should be added
to the coolant bottle. Do not overfill.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold,
the level of the coolant (antifreeze) in the bottle
should be between the “MAX” and “MIN” lines
marked on the bottle.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional coolant (antifreeze) is needed
to maintain the proper level, it should be added
to the coolant bottle. Do not overfill. See an authorized dealer for service.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compart
-
ment. This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the ther -
mostat opens, allowing hot engine coolant (anti -
freeze) to enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle
must also be protected against freezing.
If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen -
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo -
nents.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
