Operation Instructions - Auxiliary Mode
The auxiliary (AUX) jack is an audio input jack which
allows the user to plug in a portable device such as an
MP3 player or iPod® and utilize the vehicle’s audio
system to amplify the source and play through the
vehicle speakers.
Pressing the AUX button will change the mode to auxil-
iary device if the AUX jack is connected.
NOTE:The AUX device must be turned on and the
device’s volume set to the proper level. If the AUX audio
is not loud enough, turn the device’s volume up. If the
AUX audio sounds distorted, turn the device’s volume
down.
TIME Button (Auxiliary Mode)
Press this button to change the display to time of day. The

NOTE:If you experience difficulty in playing a particular
disc, it may be damaged (i.e., scratched, reflective coating
removed, a hair, moisture or dew on the disc) oversized, or
have protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in your
vehicle can cause erratic or noisy performance from your
radio. This condition may be lessened or eliminated by
relocating the mobile phone antenna. This condition is not
harmful to the radio. If your radio performance does not
satisfactorily “clear” by the repositioning of the antenna, it is
recommended that the radio volume be turned down or off
during mobile phone operation when not using Uconnect®
(if equipped).
CLIMATE CONTROLS
The air conditioning and heating system is designed to
make you comfortable in all types of weather.
Manual Heating And Air Conditioning
The Manual Temperature Controls consist of a series of
outer rotary dials and inner push knobs.

Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime 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 the
fresh air and high blower settings. 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 re-
moved 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 win-
dow fogging becomes a problem, increase blower speed.
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.
406 UNDERSTANDING YOUR INSTRUMENT PANEL

Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
Floor, Mix, or Defrost mode. The air is directed at the area
of the windows through which you view the outside
mirrors.
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 — If Equipped
The A/C Filter prevents most dust and pollen from enter-
ing the cabin. The filter acts on air coming from outside the
vehicle and recirculated air within the passenger compart-
ment. Refer to “Maintenance Procedures” in “Maintaining
Your Vehicle” for A/C Air Filter service information or see
your authorized dealer for service. Refer to “Maintenance
Schedules” for filter service intervals.

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick® shift
control (refer to “AutoStick®” in this section) to select a
lower gear. Under these conditions, using a lower gear
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
430 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control is only used
when the transfer case is in the 4L (Low) range. In the
transfer case 2H and 4H (High) positions, the AutoStick®
shift control is available (refer to AutoStick®in this
section).
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transfer case is in the 4L (Low) position, and the shift
lever is in the DRIVE position. For example, if you shift the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically, shift-
ing between all available gears. Tapping the shift lever to
the left (-) will downshift the transmission, activate ERS
mode, display the current gear in the instrument cluster,
and maintain that gear as the top available gear. Once in
ERS mode, tapping the shift lever to the left (-) or right (+)
will change the top available gear.
To exit ERS mode, simply press and hold the shift lever to
the right (+) until “D” is once again displayed in the shift
lever position indicator in the instrument cluster.

STARTING AND OPERATING 431

•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
