2013 JEEP WRANGLER UNLIMITED engine

Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.
CAUTION!Prolonged driving with the MIL on could cause damage
to the engine control system. It also could affect fuel
economy and drivability. If the MIL is flashing, severe
catalytic converter damage and power loss will soon
occur. Immediate service is required. WARNING!A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
26. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the312 UNDERSTANDING YOUR INSTRUMENT PANEL

engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
The “ESC Off Indicator Light” and the “ESC Activation/
Malfunction Indicator Light” come on momentarily each
time the ignition switch is turned to ON/RUN.
Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously. The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver that
caused the ESC activation.
WARNING!The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent acci-
dents, including those resulting from excessive speed
in turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of an ESC-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

27. Sway Bar Indicator Light — If Equipped
This indicator will illuminate when the front
sway bar is disconnected.
28. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
29. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash depending on the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the shift
lever is placed in the PARK position. The light should
turn off. If the light remains on with the engine running,
your vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
If the light continues to flash when the engine 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 first turned to ON/RUN
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.314 UNDERSTANDING YOUR INSTRUMENT PANEL

Control Buttons
The Compass/Temperature control buttons are located
on the left spoke of the steering wheel.
Press and release the STEP button on the steering wheel
to access the options in the Compass display. 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.
The following displays can be reset or changed:
• Compass/Temperature
• AVG ECO (changes to present fuel economy)
• ET (will reset display)
• DTE (distance to empty)
These messages can be cycled through by pressing the
STEP button on the steering wheel. To reset the AVG ECO
or ET, press and hold the STEP button for approximately
three seconds.Mini-Trip Control Buttons316 UNDERSTANDING YOUR INSTRUMENT PANEL

Compass/Temperature Display
NOTE: If the vehicle is equipped with a Chrysler
Uconnect™ gps (Navigation Radio), the NAV system will
provide the compass direction, and the variance and
calibration menus will be unavailable. The compass will
perform accurately, based on GPS signals instead of the
Earth’s magnetic field.
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
differences and provide the most accurate compass head-
ing. To Set The Variance
Start the engine and leave the transmission gear selector
lever in the PARK position. Press and hold the RESET
button on the steering wheel (for approximately ten sec-
onds) until the current variance zone number is displayed. Compass Variance Map

To change the zone, press and release the STEP button to
increase the variance one step. Repeat as necessary until
the desired variance is achieved.
NOTE: The factory default zone is 8. During program-
ming, the zone value will wrap around from zone 15 to
zone 1.
Manual Compass Calibration
If the compass appears erratic, inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-
ing the compass, make sure the proper zone is selected.
1. Start the engine and leave the transmission in the
PARK position. 2. Press and hold the RESET button (for approximately
10 seconds) until the current variance zone number is
displayed.
3. Release the RESET button, then press and hold again
for approximately 10 seconds, until the direction is
displayed, with the CAL indicator on continuously in
the display.
4. To complete the compass calibration, drive the vehicle
in one or more complete 360–degree circles, under
5 mph (8 km/h) in an area free from power lines and
large metallic objects, until the CAL indicator turns
off. The compass will now function normally.318 UNDERSTANDING YOUR INSTRUMENT PANEL

• Check Gascap (refer to “Adding Fuel” in “Starting
And Operating” for more details)
• Oil Change Required (with a single chime)
• ECO (Fuel Saver Indicator) — if equipped
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style. Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
MENU button. To reset the oil change indicator system
(after performing the scheduled maintenance), perform
the following procedure:
1. Turn the ignition switch to the ON position. Do not
start the engine .
2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

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.
