Information overview
Read and observe
on page 40 first.
Overview of driving data (depending on the vehicle equipment).
Range
The detail provides information about the distance in km, that can be travelled
with the current tank and with the same driving style.
40Using the system
If you drive more efficiently this value can increase.
Average fuel consumption
The indication is calculated continuously since the last deletion of the memory.
After erasing the memory, no data will appear for the first 100 m driven.
Current fuel consumption
You can use this information to adapt your driving style to the desired fuel
consumption.
When the vehicle is stationary or slowly moving the fuel consumption is dis-
played in l/h (on models for some countries the following appears --,- km/l).
Oil temperature
If the engine oil temperature is in the range of 80-110 °C, the engine operating
temperature has been reached.
If the oil temperature is lower than 80 °C or above 110 °C, avoid high engine
revs, full throttle and high engine loads.
If the oil temperature is lower than 50 °C or if there is a fault in the system for
checking the oil temperature are displayed instead of the oil temperature.
Warning against excessive speeds
Set the speed limit, for example, for the maximum permissible speed in town
» page 41 .
Current driving speed
The display is identical to the display on the speedometer.
Average speed
The indication is calculated continuously since the last deletion of the memory.
After erasing the memory, no data will appear for the first 300 m driven.
Distance travelled
The distance travelled since the memory was last erased is displayed.
The maximum distance indicated is 9,999 km. The indicator is automatically
set back to zero if this period is exceeded.
Driving time
The time travelled since the memory was last erased is displayed.
The maximum distance indicated is 99 hours and 59 minutes. The indicator is
automatically set back to zero if this period is exceeded.Coolant temperature
If the engine oil temperature is in the range 80-110 °C, the engine operating
temperature is reached.
If the temperature lies below 80 °C or above 110 °C, avoid high engine revs, full
throttle and high engine loads.
