• The compass does not display the correct

heading and the compass zone variance

is set correctly.

In order to calibrate, CAL must be displayed in the

mirror compass windows. If CAL is not displayed,

push the on/off button for approximately

12 seconds or until CAL is displayed.

The compass can be calibrated by driving the

vehicle in circles at 5 mph (8 km/h) or less until the

display reads a direction.

Compass Variance

The mirror is set in zone eight upon leaving the

factory. It will be necessary to adjust the compass

to compensate for compass variance if the

vehicle is outside of zone eight. Under certain

circumstances, as during a long distance

cross-country trip, it will be necessary to adjust for

compass variance. Compass variance is the

difference between earth’s magnetic north and true

geographic north. If not adjusted to account for

compass variance, the compass could give

false readings.

To adjust for compass variance, do the following:

1. Find your current location and variance

zone number on the following zone map.

2. Press and hold the on/off button untilaZand

a zone number appears in the display. The

compass is now in zone mode.

3. Keep pressing the on/off button until the

desired zone number appears in the display.

Release the button. After approximately

four seconds of inactivity, the new zone

number will be locked in and the compass/

temperature display will return.
