Computer
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.5 7/+36, on
bridges or shaded road surfaces, for
instance.<
Average fuel consumption
If you press the onboard computer but-
ton BC in the turn signal lever for longer
while the average fuel consumption is
being displayed, a new consumption
value is calculated from that point in
time.
If you wish, you can have the aver-
age fuel consumption displayed in
a different unit of measure.<
Range
The display shows a range estimate
based on the available fuel. The amount
of fuel remaining in the tank is mea-
sured, the estimated range is calcu-
lated taking into account the operating
conditions over the last 20 miles/30 km.
It is important that you refuel when
the cruising range falls below
approx. 35 miles/50 kilometers. Other-
wise, the engine cannot be guaranteed
to operate properly and damage may
result.<
Average speed
Any time spent when the vehicle is sta-
tionary and the engine is shut off is
ignored for the calculation.
To reset the average speed: press the
onboard computer button BC in the
turn signal lever for approx. 2 seconds.
