rearview mirror so you can see clearly behind your

and side to side. The day/night control, located at

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.
