The speedometer shows the speed in both kilometers per hour (km/h) and miles per hour (mph).
The vehicle's odometer works together with the Driver Information Center (DIC). Trip A and Trip B can be set on the odometer. See “Trip Information” under DIC Operation and Displays.
The vehicle does not have to be running to check the odometer mileage. Simply open the driver's door and the mileage briefly displays.
If the vehicle ever needs a new odometer installed, the new one will be set to the correct total mileage of the old odometer.
