Automatic Gearbox
196
Use of the engine brake
When the engine brake is operated in third or higher gear, the ECU will shift down to
second gear as soon as the engine speed permits to do so.
This is in order to allow the engine brake to deliver maximum braking force.
The selector display shows the second gear selected by the ECU.
Using the PTO
If the vehicle is fitted with a PTO, this can be switched on in both neutral and first
gear (depending on the version).
PTO operation is, however, not permitted in Drive when the vehicle is being held
stationary by the service brake or parking brake. In this case, shift to neutral in order
to prevent overheating. Depending on the version, the electronic unit will shift the
gearbox to neutral if a command is given to do so.
Faults
If the transmission fault warning symbol in the master display lights up, there is a
fault in the gearbox (shifting gears), or the temperature of the gearbox oil is too
high.
The accompanying fault code can be read in the selector display function.
Read the following recommendations first or consult an authorized dealer if
necessary.
