The connection of the positive ignition terminal is tested next.

The reversing light function is tested next.
✔ A gear switch symbol appears in the display.
6 Now switch to reverse gear.
✔ If the switching signal was detected, a smiling face appears.
Finally, the speedometer signal is tested.
✔ A speedometer symbol appears.
7 Drive a short distance at a speed of no more than 19 mph.
✔ If the speedometer signal was detected, a smiling face appears and the
display switches to calibration status.
Note: If a sad face appears after the speedometer signal is tested,
check the signal connection and measuring point in the vehicle. If
in doubt, please contact your authorized workshop. In some cases
it is possible that the speedometer signal is incompatible. If this is
so, a wheel sensor will need to be installed.
8 Now drive a distance of approx. 4 to 10 miles.
✔ The calibration process is completed when the indicator bar is complete-
ly filled in.
Note: Navigation is not possible during the calibration process.
The route that you have to drive along depends on various factors
such as the quality of GPS reception and the route itself. The spec-
ified distance in miles is only an average value. It can also be short-
er or considerably longer if conditions are poor.
