Calibrating the compass

The earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. A "
C " will be displayed if cali-
bration becomes necessary.
To calibrate the compass:
1. Stop the car in a large, open area, away
from traffic.
2. Using a pen or similar object, hold the but-
ton (1) depressed for at least 6 seconds.
"
C " will be displayed.
