Ignition JEEP WRANGLER 2012 JK / 3.G Service Manual

30. Electronic Throttle Control (ETC) LightThis 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.

Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. DTE cannot be reset.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE display value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to a text display of LOW FUEL”. This display will
continue until the vehicle runs out of fuel. Adding a
significant amount of fuel to the vehicle will turn off the
LOW FUEL text and a new DTE value will display.
Elapsed Time
Shows the total elapsed time of travel since the last reset.
Elapsed time will increment when the ignition switch is
in the RUN or START position.
Elapsed time is displayed as follows:
hours:minutes:seconds
Elapsed time can be reset by pressing and holding the
SELECT button (as prompted in the EVIC display). Upon
reset all digits will change to zeros and time will start
incrementing again if the ignition switch is in RUN or
START.
