JEEP WRANGLER 2010 Owners Manual

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.

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 the
life 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.

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.
