PROCESSES FOR ADJUSTING THE COMPASS
VARIANCE

M1524012000053

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, your compass could give
false readings.

1. Press the "COMP" button for more than 3 seconds. The

current zone number will appear in the display.

2. Find your current location and variance zone number on the

map given on the left.

3. Press the "COMP" button until the new zone number

appears in the display.
After you stop pressing the button in, the display will show a
compass direction within a few seconds.
NOTE: Do not install the ski rack, antenna, etc. Which are
attached to the vehicle by means of a magnet. They affect
the operation of the compass.
NOTE: If the compass deviates from the correct indication
soon after repeated adjustment, have the compass checked
at an authorized Mitsubishi dealer.
NOTE: The compass may not indicate the correct compass
point in the places shown below:

• Tunnels

• Areas along he railroad

• Underpass

• Transforming station

• Area with many office buildings

• Area over the subway

• Up or down a steep hill

The compass returns to the correct compass point when the
vehicle moves to an area where the geomagnetism in stabi-
lized.

LED light to the right of the main display switch will be lit
when the mirror is on. If it's not, depress the "TEMP" side of
the main display switch for 15 seconds.

1. Cover the forward-facing light sensor on the back of the

mirror with a black cloth.

2. While in a well-lit area, make sure light strikes the sensor on

the front of the mirror, simulating glare from vehicles behind
you. The mirror will dim within 2 minutes if the testing for the
first time. If the mirror does not dim, replace the inside rear
