Mirror Operation

(On/Off): Press and hold the button, located on the

lower left side of the mirror face, for about three seconds

to turn the automatic dimming feature on or off. The

indicator light will illuminate when this feature is active.

The automatic dimming feature is active each time the

vehicle is started.

Compass Operation

Press the on/off button once to turn the compass on

or off.

When the ignition and the compass feature are on, the

compass will show two character boxes for about

two seconds. After two seconds, the mirror will display

the compass heading.

Compass Calibration

If after two seconds, the display does not show a

compass heading (for example, N for North), there may

be a strong magnetic ﬁeld interfering with the compass.

Such interference may be caused by a magnetic antenna

mount, magnetic note pad holder or a similar magnetic

item. If the letter C should ever appear in the compass

window, the compass may need calibration.

The mirror can be calibrated by driving the vehicle in

circles at 5 mph (8 km/h) or less until the display reads

a direction.

The compass can be placed in calibration mode manually

by pressing and holding the on/off button untilaCis

shown in the compass display.

Compass Variance

The zone is set to zone eight upon leaving the factory. It

will be necessary to adjust the compass to compensate

for compass variance if you live outside 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,

your compass could give false readings.
