Adapting fuel consumption display - RA54001070424X(54-424)

If the fuel consumption displayed by the trip computer deviates from the actual consumption, it can be adapted in 2.5% stages by adjusting the microswitches on the trip computer control unit.

Fig 1: Identifying Trip Computer Control Unit

Example: - Effective

consumption: 12.5 l/100 km

- Trip computer

consumption display: 11.7 l/100 km

Error in %= -6.4%

Consumption correction on microswitches+7.5%.

If the fuel consumption displayed on the trip computer deviates from the actual consumption, it can be adapted in 2.5% stages.

Setting consumption correction 

1. Turn key in steering lock to position 2 (terminal 15, engine off).
2. Hold down clock synchronization button "A" for at least 2 seconds.

3. Pull out clock adjustment knob, turn counterclockwise and release.
   • The stored value is visible in the outside temperature display (factory setting 0%).

4. Change consumption correction value
   • Pull out clock adjustment knob and turn counter-clockwise.

The adjustment range extends from +25% to -25%.

Calculating adjustment range

Example:

Effective consumption 12.5 l

Trip computer consumption display 11.7 l

Error in %=6.4%

Set next highest correction +7.5.
