Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is calculated
on the basis of the way the car has been driven
over the last 18 miles/30 km and the amount of
fuel currently in the tank.
It is important that you refuel as soon as
possible once your cruising range falls
below 30 miles/50 km; otherwise, engine func-
tions are not ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
switched off are not included in the calculations
of average speed.
To reset average speed: press the button in the
turn indicator lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
To reset average fuel consumption: press the
button in the turn indicator lever for approx.

Activating DTC
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
