GMC Envoy XUV Automobile User Manual


 
Temperature and Compass Display
O
(On/Off): Press this button to turn the compass and
temperature display on or off. The compass display,
can show a maximum of two characters. For example,
NE is displayed for north-east.
When the ignition and the compass/temperature
feature are on, character boxes will appear for about
two seconds. After two seconds, the mirror will
display the direction the vehicle is facing and the
outside temperature.
To set the temperature in Fahrenheit or Celsius,
do the following:
1. Press and hold the on/off button until either a
flashing F or C appears.
2. Press the button again to change the display to the
desired unit of measurement. After about four
seconds of inactivity, the new unit will be locked in
and the compass/temperature display will return.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass direction, 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. If the letter C
should ever appear in the compass window,
the compass may need calibration.
Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror
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 conditions, such as during a long-distance,
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for
compass variance, the compass could give false
readings.
