Automatic Dimming Mirror Operation

Press and hold the TEMP button for approximately

eight seconds to turn the automatic dimming feature on

or off. The indicator light to the left of the TEMP

button will turn on or off to indicate when the feature is

on. Once the mirror is turned off, it will remain off

until it is turned back on, or until the vehicle is restarted.

Compass Operation

Press the COMP button once brieﬂy to turn the compass

on or off.

When the ignition is started and the compass feature is

on, the compass will show two character boxes for

approximately two seconds. After two seconds,

the mirror will display the compass heading.

Compass Calibration

The compass may need calibration if one of the

following occurs:

• If CAL is displayed while driving in the vehicle.

• After approximately ﬁve seconds, the display does

not show a compass heading, N for North, for

example, 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.

• 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

in the COMP button for approximately eight 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 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.

To adjust for compass variance:

1. Find your current location and variance zone

number on the following zone map.

2-54
