JEEP WRANGLER 2009 Owners Manual

NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
25. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON position, before engine start. If the bulb does
not come on when turning the key from OFF to ON, have
the condition checked promptly.
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.

WARNING!
If a warning light remains on the system may not be
working and you will not have the benefit of ESP or
BAS. Under certain driving conditions, where ESP or
BAS would be beneficial, you - if you have not
adjusted your driving speeds and stopping in or to
account for the lack of the feature, may be in acci-
dent.
30. 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 ON and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.

Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.
After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the PARK position (if equipped).If the compass appears erratic or inaccurate and the
variance has been properly set, you may wish to manu-
ally recalibrate the compass. To manually calibrate the
compass:
1. First enter the variance mode. Press and hold the left
button (located on the instrument cluster) for approxi-
mately 10 seconds to enter the variance mode, and
release the button when the VAR (Compass Variance)
symbol appears.
2. The current variance value will also be displayed.
Once in the variance mode, it is necessary to release the
button, and then press and hold it again (approximately
10 seconds) until CAL is displayed (solid, not blinking).

NOTE:The U.S./Metric display will change from En-
glish to Metric or Metric to English before the VAR
symbol appears, however, it will revert back to its
original setting after programming the compass func-
tions.Outside Temperature
If the outside temperature is more than 131°F (55°C), the
display will show 131°F (55°C). When the outside tem-
perature is less than 40°F (40°C), the display will
show 40°F (40°C).
