Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured with
ISOFIX or i-Size and the vehicle. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether belt,
this should always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.
If the rear seat backrest is not engaged and
locked, the red lock verification indicator will be
visible (Y page 292).
Top Tether anchorages The Top Tether anchorage points are located on
the rear side of the backrests on both outer rear seats.
Vehicles with adjustable head restraints:
X Move head restraint :upwards.
X Route Top Tether belt ?under head
restraint :between the two head restraint
bars.
Vehicles without adjustable head restraints:
X Top Tether belt with one belt strap: route
Top Tether belt ?centrally over head
restraint :.
or X Top Tether belt with two belt straps: route
one Top Tether belt ?to the left and one to
the right past the side of head restraint :.
All vehicles:
X Fit the ISOFIX or i-size child restraint system
with Top Tether. Always comply with the child
restraint system manufacturer's installation
instructions when doing so.
X Hook Top Tether hook =of Top Tether
belt ?into Top Tether anchorage ;.
Ensure that:
R Top Tether hook =is hooked into Top
Tether anchorage ;as shown
R Top Tether belt ?is not twisted
R Top Tether belt ?is routed between the
rear seat backrest and the luggage com-
partment cover if the luggage compart-
ment cover is fitted
X Tension Top Tether belt ?. Always comply
with the child restraint system manufactur-
er's installation instructions when doing so.

WARNING
If the driver's seat is not correctly engaged, it could unexpectedly move while driving. This
could cause you to lose control of the vehicle. There is a risk of an accident.
Always ensure that the driver's seat is
engaged before starting the vehicle. G
WARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If liquid
is spilled on the seats, dry them as soon aspossible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The seats should only be occupied by passen-
gers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.

The convex exterior mirrors provide a larger field of vision.
After the engine has been started, the exterior
mirrors are automatically heated at low outside
temperatures. Heating takes a maximum of ten
minutes.
i The exterior mirrors can also be heated

WARNING
Electrolyte may escape if the glass in an auto- matic anti-dazzle mirror breaks. The electro-
lyte is harmful and causes irritation. It must
not come into contact with your skin, eyes,
respiratory organs or clothing or be swal-
lowed. There is a risk of injury. Mirrors

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. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly 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 tail-
gate. Never drive with the tailgate open. G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle.
Observe the following notes on loading and
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 store objects.
R position heavy loads as far forwards as pos-
sible and as low down in the luggage com-
partment 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 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

Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction. 288
