2013 JEEP WRANGLER engine

NOTE:The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.
ECO (Fuel Saver Mode) — If Equipped
The ECO message will display below the outside tem-
perature in the EVIC display (if the audio system is on
the ECO indicator will override the audio information
display line if the Display Fuel Saver personal setting is
ON — see Personal Settings section). This message will
appear whenever you are driving in a fuel efficient
manner.
This feature allows you to monitor when you are driving
in a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to set the compass manually. When the vehicle is
new, the compass may appear erratic and the EVIC will
display “CAL” until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
metallic objects) until the “CAL” message displayed in
the EVIC turns off. The compass will now function
normally.
NOTE:
A good calibration requires a level surface and an
environment free from large metallic objects such as build-
ings, bridges, underground cables, railroad tracks, etc.

Manual Compass Calibration
If the compass appears erratic and the “CAL” indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Start the engine. Leave the shift lever in PARK in orderto enter the EVIC Programming Menus.
2.
Press the MENU button until Personal Settings
(Customer-Programmable Features) displays in the EVIC.
3. Press the DOWN button until “Calibrate Compass” displays in the EVIC.
4.
Press and release the SELECT button to start the calibra-
tion. The “CAL” indicator will display in the EVIC.
5. Complete one or more 360–degree turns (in an area free from large metal or metallic objects) until the
“CAL” indicator turns off. The compass will now
function normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly set,
the compass will automatically compensate for the differ-
ences and provide the most accurate compass heading.
NOTE: Magnetic materials should be kept away from
the top of the instrument panel; this is where the compass
sensor is located.

2. Press the MENU button until Personal Settings (Customer-Programmable Features) displays in the
EVIC.
3. Press the DOWN button until “Compass Variance” message and the last variance zone number displays
in the EVIC.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pressing the Recirculation button. However,
under certain conditions, while in Automatic mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pressed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation mode at this time. If you would like the
system to go into Recirculation mode, you must first
move the Mode knob to Panel, Bi-Level and then press
the Recirculation button. This feature reduces the
possibility of window fogging.Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system in air-conditioned vehicles
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 Chrysler Material Standard MS-12106
and 50% water is recommended. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection.
