The Compass can be turned ON and

when the ignition is cycled. To turn the
display feature ON/OFF:

button to
turn the display feature OFF.

There is a difference between magnetic
north and true north. The compass in the
mirror can compensate for this difference
when it knows the Magnetic Zone in
which it is operating. This is set either by
the dealer or by the user. The operating
Zone Numbers for North America are
shown in the figure on the following sec-
tion.
