humidity are present. Recirculation can be used in
all modes except for Defrost. Recirculation may be
unavailable if conditions exist that could create fogging on the inside of the windshield. The A/C
can be deselected manually without disturbing the
mode control selection. Continuous use of the
Recirculation mode may make the inside air stuffy
and window fogging may occur. Extended use of
this mode is not recommended.
On systems with Manual Climate Controls, the
Recirculation mode is not allowed in Defrost mode
to improve window cleaning operation.
Recirculation is disabled automatically if this mode
is selected. Attempting to use Recirculation while
in this mode causes the LED in the control button
to blink and then turn off.
Front Defrost Setting
Turn the mode control knob to the Front
Defrost mode setting. Air comes from the

OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. 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 Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 461.
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 obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
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.

PREMIUM INSTRUMENT CLUSTER
D
ESCRIPTIONS — DIESEL

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Instrument Cluster Display
When the appropriate conditions exist, this
display shows the instrument cluster
display messages Ú page 114.
The display always shows one of the main
menu items after ignition on.
3. Speedometer
Indicates vehicle speed.
4. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level of
Diesel Exhaust Fluid in the DEF tank. DEF is
required to maintain normal vehicle opera -
tion and emissions compliance. If some -
thing is wrong with the gauge, a DEF
Warning Message or Malfunction Indicator
Light (MIL) will be displayed Ú page 125.
NOTE:
• The DEF tank on these vehicles is
designed with a large amount of full
reserve. So the level sensor will indicate
a full reading even before the tank is completely full. To put it another way,
there’s additional storage capacity in the
tank above the Full mark that’s not repre
-
sented in the gauge. You may not see any
movement in the reading – even after
driving up to 2,000 miles (3,219 km) in
some cases.
• The gauge may take up to five seconds to update after adding a gallon or more of
DEF to the DEF tank. If you have a fault
related to the DEF system, the gauge may
not update to the new level. See an
authorized dealer for service.
• The DEF gauge may also not immediately update after a refill if the temperature of
the DEF fluid is below 12°F (-11°C). The
DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update
after a period of run time. Under very cold
conditions, it is possible that the gauge
may not reflect the new fill level for
several drives.
• Outside temperature can affect DEF consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not
move for extended periods of time. This is
a normal function of the system.
5. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition switch is in the
ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel filler door is located.
INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an instrument
cluster display, which offers useful information to
the driver. With the ignition in the OFF mode,
opening/closing of a door will activate the display
for viewing, and display the total miles, or
kilometers, in the odometer. Your instrument
cluster display is designed to display important
information about your vehicle’s systems and
features. Using a driver interactive display located
on the instrument panel, your instrument cluster
display can show you how systems are working and
give you warnings when they are not. The steering
wheel mounted controls allow you to scroll through
the main menus and submenus. You can access
the specific information you want and make
selections and adjustments.

What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte -
rior).
Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, USB ports.
Check HVAC settings (blower, temperature).
Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when applicable.
These indications are indicative and precautionary
and as such must not be considered as exhaustive
and/or alternative to the information contained in
the Owner’s Manual, which you are advised to read
carefully in all cases. Always refer to the
information in this chapter in the event of a failure
indication. All active telltales will display first if
applicable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are optional
and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and will
turn on for four to eight seconds as a bulb
check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light will
illuminate with a single chime when a fault with the
air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during
startup, stays on, or turns on while driving, have
the system inspected at an authorized dealer as
soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the
parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full
mark on the master cylinder reservoir, it indicates
a possible brake hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition has
been corrected. If the problem is related to the
brake booster, the ABS pump will run when
applying the brake, and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual
brake system is indicated by the Brake Warning
Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a
specified level.
The light will remain on until the cause is corrected.
