GWarning!
No racks or loads may be secured to the roof
of the vehicle, as
R the panorama roof* may be damaged, thus
injuring persons
R this can have a substantial adverse
effect on the driving dynamics of the
vehicle, thus causing accidents
R the rack and/or the load could detach and

people could be injured by the load and/
or rack that has fallen off
GWarning!
Make sure the tailgate is closed when the
engine is running and while driving.
Among other dangers, deadly carbon
monoxide (CO) gases may enter vehicle

GWarning!
The manufacturer has not approved your
vehicle for towing a trailer. A trailer can
permanently impair driving safety.
The gross vehicle weight which is the
weight of the vehicle including fuel, tools,
installed accessories, passengers, and
luggage/cargo must never exceed the load
limit and the Gross Vehicle Weight Rating
(GVWR) for your vehicle as specified on the
placard located on the driver’s door
B‑pillar ( Y page 198). In addition, the
load must be distributed in such a way so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the
certification label which can be found on
the driver’s door B‑pillar.
For more information, see “Loading the
vehicle” ( Y page 120).
The handling characteristics of a fully
loaded vehicle depend greatly on the load
distribution. It is therefore recommended
to load the vehicle with the heaviest items
being placed towards the front of the
vehicle.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
R Always place items being carried
against seat backrests, and fasten them
as securely as possible.
R The heaviest portion of the cargo should
always be kept as low as possible against
seat backrests.
R Do not stack loads higher than the top
edge of the head restraints.
R Make sure no luggage/cargo items can get
above or next to the driver’s and/or
passenger seat into the passenger
compartment.
R Make sure luggage/cargo is properly
secured.
R Always use, if so equipped, cargo net*
when transporting cargo.
