Stowage areas
Loading guidelines
GWARNING
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, particularly in the event of
sudden braking or a sudden change in
direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before
the journey.
GWARNING
Combustion engines emit poisonous
exhaust gases such as carbon monoxide. If
the tailgate is open when the engine is
running, particularly if the vehicle is
moving, exhaust fumes could enter the
passenger compartment. There is a risk of
poisoning.
Turn off the engine before opening the
tailgate. Never drive with the tailgate
open.
Your vehicle has not been approved by the
manufacturer for towing a trailer. A trailer
could seriously impair driving safety.
Mounting a basic rack, a cycle rack or a ski/
snowboard rack on the rear of the vehicle will change the axle load distribution as speci-
fied by the vehicle manufacturer. Read the
operating instructions for the individual
accessories.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load:
Rnever exceed the maximum permissible
gross vehicle weight or the permissible
axle loads for the vehicle (including occu-
pants). The values are specified on the
vehicle identification plate on the B-pil-
lar of the driver's door
Rthe load must not protrude above the upper
edge of the head restraints
Rensure that no items of luggage can enter
the vehicle interior above or between the
front seats
Rensure that loaded objects are stowed
safely and are secured
Rload heavy objects at the bottom and light
objects at the top
Stowage space
Important safety notes
GWARNING
If you stow objects in the vehicle interior
in an unsuitable way, they could slip or be
thrown around and thus hit vehicle occu-
pants. Additionally, the cup holders, open
stowage spaces and mobile phone brackets
cannot restrain the objects placed in them
in the event of an accident. There is a risk
of injury, especially in the event of brak-
ing or sudden changes in direction.
RAlways stow objects so they cannot be
thrown around in these or similar situa-
tions.
RAlways ensure that objects do not pro-
trude from the stowage compartments or
stowage nets.

Information about Service
Resetting the service display
!Have service work carried out as descri-
bed in the Maintenance Booklet. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a smart center, will reset the service interval dis-
play after the service work has been carried
out. You can also obtain further information
on maintenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
Rregular city driving with frequent inter-
mediate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long
periods
In these or similar operating conditions,
have, for example, the air filter, engine oil
and oil filter changed more frequently. The
tires must be checked more frequently if the
vehicle is operated under increased loads.
You can obtain further information at a
qualified specialist workshop, e.g. a smart
center.
Driving abroad
An extensive smart service network is also
available in other countries. For further
information inquire at any smart center.
