The steerable additional axle is malfunctioning and only steers pas‐
sively. Stability Control Assist may also have been deactivated as a
result. If Stability Control Assist is deactivated, the yellow

event window displays
ESP not available
.
In extreme driving conditions, e.g. when braking hard on a slippery
or uneven carriageway, the steerable additional axle may deactivate
itself. It will then only steer passively. On vehicles with a height-
adjustable trailing axle, it is no longer possible to lower the addi‐
tional axle while the vehicle is moving.
WARNING! If Stability Control Assist is deactivated due to a faulty
steerable additional axle, the vehicle's stability is decreased.
There is a risk of an accident.
#
Drive on carefully and stop at the next available opportunity.
Adjust your driving style to the changed handling and steering
characteristics.
#
Stop the vehicle and switch off the engine.
#
Start the engine after approximately ten seconds.
The event window goes out. The steerable additional axle is
reactivated.
#
If the event window does not disappear: have the steerable addi‐
tional axle checked at a qualified specialist workshop.
