COMPASS CALIBRATION 

1. Start the vehicle. 

2. Locate the electronic compass/temperature display on the overhead console, press and hold the MODE 

button until CAL appears in the display, then release the MODE button. 

3. Drive the vehicle slowly (less than 5 km/h [3 mph]) in complete circles until CAL disappears from the 

display.  

VEHICLE DEMAGNETIZING 

1. Demagnetize the front third of the vehicle roof. 

1. Turn on the demagnetizer at least 1 m (3 ft) away from the vehicle.  

2. Holding the demagnetizer no more than 2.5 cm (1 in) from the vehicle roof and starting on the 

passenger side, demagnetize the front third of the vehicle roof closest to the windshield using a 
constant circular motion. Keep the circle radius within 30 cm (12 in) while sweeping across the 

NOTE:

For optimum calibration, drive to an open, level location away from large 
metallic objects or structures. Switch off all non-essential electrical 
accessories (rear window defrost, heater A/C, map lamps, wipers, etc.) and 
make sure all doors are closed.

NOTE:

To exit CAL mode before carrying out a compass adjustment, turn the 
ignition switch to the OFF position.

NOTE:

If the CAL indicator does not turn off after the vehicle has been driven in a 
circle no more than five times, demagnetize the vehicle and repeat the 
procedure.

CAUTION: During demagnetizing, the demagnetizer coil will be pulled toward the 

vehicle. Place a cloth over the vehicle roof to protect the vehicle surface if 
contact occurs. Make sure the cloth covers the front third and the entire 
width of the roof.

NOTE:

The demagnetizing process requires the use of a demagnetizing coil commonly 
used by television repair technicians to demagnetize television tubes.

NOTE:

To demagnetize, use a constant circular motion over the vehicle roof. Do not 
turn off the demagnetizer while sweeping the vehicle roof to prevent re-
magnetizing ferrous materials contained in the vehicle.

NOTE:

During the demagnetizing process, make sure the phenolic surface of the tool 
(the side opposite the handle) is closest to the vehicle surface.
