Owner's Manual

This Owner's Manual describes all models and
all standard and optional equipment available for
your vehicle at the time of this Owner's Manual
going to press. Country-specific differences are
possible. Note that your vehicle may not be fit‐
ted with all features described. This is also the
case for systems and functions relevant to
safety. Therefore, the equipment on your vehicle
may differ from that in the descriptions and illus‐
trations.
The original purchase agreement for your vehicle
contains a list of all of the systems in your vehi‐
cle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are
important documents and should be kept in the
vehicle.
