Cadillac escalade ext 2002 ユーザーズマニュアル

Press the COMP button once briefly to turn the compass
on or off.

When the ignition and the compass feature are on, 
the compass will show two character boxes for
approximately two seconds. After two seconds, 
the mirror will display the compass heading.

When cleaning the mirror, use a paper towel or similar
material dampened with window cleaner. Do not spray
window cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.

The compass may need calibration if:
D After 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.

D 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 in one of two ways:
D Drive the vehicle in circles at five mph (8 km/h) or

less until the display reads a direction, or

D drive the vehicle on your everyday routine and after

several turns the compass will become calibrated and
will display a direction.
