perature indicator appears and a snowflake symbol
(display for low temper-
ature) flashes for a few seconds, then remains displayed together with the
outside temperature.
Driving time - Driving time since last clearing the memory.
Current fuel consumption - When the vehicle is stationary or moving slowly,
the fuel consumption is displayed in l/h (in models in some countries the fol-
lowing appears --,- km/l). With G-TEC vehicles the current consumption of the
fuel currently being used is displayed ( with regards to a stationary or slow
moving vehicle, the natural gas consumption is displayed in kg/h).
Average fuel consumption - Is calculated continuously since the last clearing
of the memory. After erasing the memory, no data will appear for the first 300
m driven. With G-TEC vehicles, the average consumption of fuel currently being
used is displayed.
Natural gas quality The details of the quality of natural gas are displayed as a
percentage of between 70% to 100%. The higher the value of natural gas, the
lower is the consumption.
Range - Drive distance in km which can be covered with the existing tank ca-
pacity and with the same driving style. If you drive more efficiently this value
can increase. With G-TEC vehicles the following details are displayed - Range
with natural gas / petrol.
Distance driven - Distance driven since the memory was last cleared.
Total distance travelled - Odometer
Average speed - Value constantly recalculated, for distance since last clearing
the memory. After erasing the memory, no data will appear for the first 300 m
driven.
Current Speed - Digital speedometer.
Coolant temperature - If the coolant temperature is in the range 70-120 °C,
the engine operating temperature has been reached. If the temperature is be-
low 70 ° C, high engine speeds and straining the engine should be avoided. If
the temperature is over 120 ° C, the warning light lights up the instrument
