INSTRUMENTS AND CONTROLS

Calibrating the compass

North America is divided into 15 magnetic zones
and the compass will need to be calibrated if the
vehicle is driven from one zone to another.
To calibrate the compass:
1. Stop the vehicle in a large open area, safely
out of traffic and away from steel structures
and high-tension electrical wires.
2. Start the vehicle.
NOTE
•
For best calibration results, switch off all
electrical equipment in the vehicle (climate
system, windshield wipers, audio system,
etc.) and make sure that all doors are
closed.
•
Calibration may not succeed or be incor-
rect if the vehicle's electrical equipment is
not switched off.
3. Using a pen, paperclip or similar object, press
and hold the button on the underside of mir-
ror for approx. 3 seconds until the number of
the current magnetic zone is displayed.
