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. A solution of 50% OAT (Organic
Additive Technology) coolant that meets the
requirements of FCA Material Standard MS.90032
and 50% water is recommended Úpage 312.
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 Úpage 304.
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 auto -
matically 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 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 Ú page 262.
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.
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 passenger second row door. Do not block or
place objects directly in front of the inlet grille or
heater outlets. The electrical system could
overload causing damage to the blower motor.

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Speedometer
Indicates vehicle speed.
3. Temperature Gauge
The temperature gauge shows engine
coolant temperature. Any reading within the
normal range indicates that the engine
cooling system is operating satisfactorily.
The pointer will likely indicate a higher
temperature when driving in hot weather,
up mountain grades, or when towing a
trailer. It should not be allowed to exceed
the upper limits of the normal operating
range. 4. Instrument Cluster DisplayThe instrument cluster display features a
driver interactive display Ú
page 81.
5. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the Keyless Push Button
Ignition is in the ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel door is located Ú page 137.
NOTE:The hard telltales will illuminate for a bulb check
when the ignition is first cycled.
INSTRUMENT CLUSTER DISPLAY
Your vehicle is 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
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.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized
dealer for service if your vehicle overheats
Úpage 272.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H”, turn the engine
off immediately and call an authorized dealer for
service.

234SAFETY
(Continued)
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer 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, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
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 breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit in
a parked vehicle with the engine running for
an extended period. If the vehicle is stopped in
an open area with the engine running for more
than a short period, adjust the ventilation
system to force fresh, outside air into the
vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
