Calibration
North America is divided into 15 magnetic
zones and the compass will need to be cali-
brated if the vehicle is driven into a new one
(see the magnetic zones on the map in the
following section "Selecting a magnetic
zone"). To do so:
The rear-view mirror has an integrated display
that shows the compass direction in which
the vehicle is traveling.
5. Press the button repeatedly until the
number of the desired magnetic zone
(1-15) is displayed. See the magnetic
zones on the map in the following section
"Selecting a magnetic zone").
Operation

safely out of traffic and away from steel
structures and high-tension electrical
wires.

6. Wait until C is again displayed in the mir-
ror.
7. Drive slowly in a circle at a speed of no
more than 6 mph (10 km/h) until a direc-
tion is displayed. This indicates that cali-
bration is complete.
2. Start the vehicle.
NOTE
For best calibration results, switch off

Eight different directions are shown with the
abbreviations: N (north), NE (north east), E
(east), SE (southeast), S (south), SW (south-
west), W (west) and NW (northwest).
Calibration may not succeed or be
incorrect if the vehicle's electrical
equipment is not switched off.
