Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.

workshops: (Y page 23). Loading guidelines
G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a load:
R never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the luggage compartment is the preferred
place to carry objects.
R position heavy loads as far forwards as pos-
sible and as low down in the load compart-
ment as possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R always place the load behind unoccupied
seats if possible.
R use the lashing eyelets and the luggage nets
to transport loads and luggage. R
only use lashing eyelets and fastening com-
ponents that are suitable for the weight and
size of the load.
R hook in the safety net when loading.
R the maximum load capacity of the stowage
well under the luggage compartment floor is
25 kg.
R secure the load with sufficiently strong and
wear-resistant lashing material. pad sharp
edges for protection.
! Do not position the load on one part of the
folding luggage compartment floor only. The
maximum load capacity of the folding luggage compartment floor is 100 kg. Spread the
weight evenly to avoid damaging the luggage
compartment floor. Place a solid board under the load if necessary. Please note that the
load on the luggage compartment floor will be increased when the load is lashed down. Stowage areas
