If necessary, have the generator
(alternator) and the battery checked.
When the voltage is above this value again, the
ABS is operational again and the message in
the multifunction display should disappear.
Have cruise control checked by an
authorized Mercedes-Benz Light Truck
Center.
Continue driving with added caution.
Visit an authorized Mercedes-Benz Light
Truck Center as soon as possible.
Failure to follow these instructions increases
