Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer to Compass calibration
adjustment.

Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is up
to four degrees between adjacent zones and will become noticeable as
the vehicle crosses multiple zones. A correct zone setting will eliminate
this error. Refer to Compass zone adjustment.

Compass zone adjustment

1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.

2. Press and release the
SELECT/RESET stem to scroll
through the information menu until
the message center displays HOLD
RESET FOR SETUP MENU.

3. Press and hold the
SELECT/RESET stem until the
message center displays HOLD RESET FOR SYSTEM CHECK. Do not
hold the stem down at this point as you do not want to enter the system
check. Instead, quickly release the stem and repeatedly press it again to
scroll through the setup menu until the message center displays
COMPASS ZONE XX.

4. Press and hold the SELECT/RESET stem for approximately two
seconds to enter the compass zone adjustment mode.

5. Press and release the SELECT/RESET stem until the desired zone
number appears.

6. Release the SELECT/RESET stem and allow the setup timer to expire
to exit the procedure.

Compass calibration adjustment

NOTE: For optimum calibration, drive to an open, level location away
from large metallic objects or structures. Switch off all non-essential
electrical accessories (heated rear window, heater, A/C, map lamps,
wiper, etc.) and make sure all the doors are closed.

1. Start the vehicle.
