i believe you have to find an empty parking lot or culdesac and drive in a tight circle. it should auto calibrate.

Mykll 08-01-2011 07:25 PM

Darn I was hoping something more fun like a figure 8, a la iPad.

pat@fieldsauto.com 08-01-2011 07:26 PM

slow tight left circle a few times should do the trick

El Gringo 08-01-2011 07:32 PM

You're kidding right?

No horn honking?

subzero2931 08-01-2011 07:34 PM

doors off, top off, left foot out, circle one city block 4 times and honk the horn 2 times at every corner.

pat@fieldsauto.com 08-01-2011 08:39 PM

Don't forget to wear a wig from the 80's, that's the most important part of it:)

O u some how have to enter calibration mode?

Phil T 08-02-2011 10:40 PM

No calibration mode. Just drive in the circle. I had to make three loops but it finally took. The people in the church parking lot thought I was nuts. :)

Divotmeister 08-02-2011 10:50 PM

I did 10 circles and nothing happened. After 8 days it corrected itself

oilwell1415 08-03-2011 07:40 AM

Calibrate a compass? Seriously? Why does it make you do that? North is up there, east and west are over there and over there, and south is down there. Does it correct for magnetic variation or something?

boarderpatrol 09-25-2011 11:25 PM

hahahaha you guys are hillarious, I tried it and some elderly woman called the cops on me cause she thought I was trying to do burnouts..... I had quite a blast trying to explain to the cops that my 38 000$ 2012 Jeep's compass had to be calibrated..... good thing one of the cops also had a 2012 and understood exactly what I was going through :P haha

El Gringo 09-26-2011 12:00 AM

I'm pretty sure you are all wrong.

It's a compass. You don't drive in circles to calibrate it. Just hit the little button and watch your mpg's or time or something else if you think your compass is wrong. If it is really bugging you, go buy a new regular, maintenance-free, one.

Absolutely. It is covered in the Owners Manual.

There is all kinds of stuff it there. Why someone with a Jeep wouldn't read it is beyond me.

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) 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 compass
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 vehicle
is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibration,
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 manually
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 approximately
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).
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 headings.
Verify proper calibration by checking North (N),
South (S), East (E), andWest (W). If the compass does not
appear accurate, repeat the calibration procedure in another
area.
Compass Variance (VAR)
Compass Variance is the difference between Magnetic
North and Geographic North. To ensure compass accuracy,
the compass variance should be properly set according
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 variance
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 English
to Metric or Metric to English before the VAR
symbol appears, however, it will revert back to its

original setting after programming the compass functions.

They do read! They would just rather read wrangler forum!!

My Owners manual has a "How to Claibrate" It didn;t involve driving in crop circles. Its a simple reset. As I understand things the Jeep is set in where it is made (deviation area/zone 8). I live in the NE in deviation area/zone 12.

The area/zone is formed by the diviation from magnetic North. You have to set diviation to correct a compass....be it a boat, plane or Jeep.

I didn't have a Jeep when I posted that, why would I read the manual?

Probably for the same reason that I didn't look at the date of your post. :facepalm:

Guess I didn't know you are a new owner. I didn't look in the manual but do remember the details for compass calibration from previous vehicles I have owned over 10 years ago. They were Ford products but the same reset to adjust for zone.

With a 41.2ft turning circle on the JKU one could hardly describe any circle you drive in a Jeep as "tight":p - I think the JK is about 6ft tighter....just find a big parking lot!

boarderpatrol 09-26-2011 04:10 PM

wellll driving in circles worked for me, I drove in tight circles slowly 3 times exactly and the "CAL" on my dash stopped flashing

Batson35 05-25-2012 07:42 AM

Alright I can't even get my 2010 into VAR mode I have followed the instructions to the letter and I am stuck on N.

Any suggestions it is driving me nuts!!!

daggo66 05-25-2012 07:52 AM

Did you press and hold the button for 10 seconds?

Batson35 05-25-2012 07:55 AM

I sure did I followed the instructions exactly!

mt shawn 37 05-25-2012 07:57 AM

Mine did the same thing I just left it and it eventally calibrated itself and started working fine from just drivingaround

daggo66 05-25-2012 07:58 AM

Do you have anything near the top of the dash in the center that could be interfering with the compass module? Cell phone? GPS?

mt shawn 37 05-25-2012 08:02 AM

The only thing I have near it it my gps for my nav system in the dash it didn't interfear with it. It just took a couple weeks for it to self calibrate while driving for it to start working.

Batson35 05-25-2012 08:06 AM

Nothing....just iphone in my pocket....damn thing is I can't even get into CAL...I press and hold button and NOTHING happens just switches to celsius, I've tried engine running...engine off...key in you name it.
