JEEP WRANGLER 2009 JK / 3.G Owners Manual

gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
noFUSE
If the vehicle diagnostic system determines that the
Ignition Off Draw (IOD) fuse is improperly installed, or
damaged, a “noFUSE” message will display in the odom-
eter display area. For more information on fuses and fuse
locations refer to “Fuses” in Section 7.
CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately12 seconds 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/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to 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 OFF/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.
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.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 or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.

26.Electronic Stability Program (ESP) Indicator Light /
Traction Control System (TCS) Indicator Light
If the Electronic Stability Program (ESP) /
Traction Control System (TCS) Indicator Light
begins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. This indicator light starts to flash as soon as the
tires lose traction and the Electronic Stability Program
(ESP) becomes active. The ESP/TCS Indicator Light also
flashes when TCS is active. Be sure to adapt your speed
and driving to the prevailing road conditions. If the
ESP/TCS Indicator Light is on solid, the ESP system has
been turned off by the driver or a temporary condition
exists that will not allow full ESP function.
27. O/D (Overdrive) Off Indicator Light This light will illuminate when the O/D OFF
button has been selected and overdrive has been
turned off. The O/D OFF button is located on the center
console. 28. Sway Bar Indicator Light — If Equipped
This indicator will illuminate when the front
sway bar is disconnected.
29. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Warning Light The Electronic Stability Program (ESP) / Brake
Assist System (BAS) warning light in the in-
strument cluster comes on when the ignition
switch is turned to the ON position. The light
should go out with the engine running. If the ESP/BAS
warning light comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at an authorized dealer as
soon as possible. Refer to “Electronic Brake Control
System” in Section 5 for more information.

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.

Compass Temperature Display
This display provides the outside temperature and one of
eight compass readings to indicate the direction the
vehicle is facing.
WARNING!
Even if the display still reads a few degrees above
32°F ( 0°C), the road surface may be icy, particularly
in woods or on bridges. Drive carefully under such
conditions to prevent an accident and possible per-
sonal injury or property damage.
Compass Calibration
The compass on your vehicle will automatically calibrate
when new, and will continuously adjust itself over thelife of the vehicle. If the CAL indicator is on (or flashing),
drive slowly (under 10 MPH [16 kmh]) in an open area
until the CAL indicator is off.
NOTE:
•A good calibration requires a level surface and an
environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.
•Magnetic and battery powered devices, (such as cell
phones, iPod’s, radar detectors, PDA’s and laptops)
should be kept away from the top of the instrument
panel. This is where the compass module is located
and such devices may interfere and cause false com-
pass readings.

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).
216 UNDERSTANDING YOUR INSTRUMENT PANEL

3. Manual compass calibration has been initiated. Drive
the vehicle slowly in one or more circles under 5 mph
(8 km/h) in an area free from large metal objects until the
CAL symbol is extinguished.
When the CAL symbol is no longer displayed, the
compass is calibrated and should display correct head-
ings. Verify proper calibration by checking North (N),
South (S), East (E), and West (W). If the compass does not
appear accurate, repeat the calibration procedure in an-
other area.
Compass Variance (VAR)
Compass Variance is the difference between Magnetic
North and Geographic North. To ensure compass accu-
racy, the compass variance should be properly set accord-
ing to the variance map for the zone where the vehicle
will be driven. When properly set, the compass will
automatically account for this difference.
Setting the Compass Variance
Refer to the variance map for the correct compass vari-
ance zone. To check the variance zone, the ignition must
be ON. Press and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode and release the button when the VAR
symbol appears. The current variance value will also be
displayed. To change the zone, press the left button once
to increment the zone. The default is Zone 8. After Zone
15, the values will wrap around to Zone 1. When the
correct zone is displayed (per the Compass Variance
Zone Map) for the zone that the vehicle is located in, wait
for about five seconds; then the trip computer will store
the variance value in memory and the compass will
resume normal operation.

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).
