55tem, make sure that it is engaged in the
securing rings on both sides.
To ensure that the child restraint system
can perform its protective function as
intended, the backrest of the outer seat in
the 2nd row must be in the upright position. G
Risk of injury
Please note that child restraint systems
cannot provide a protective function if they
or their retaining systems are damaged or
subjected to a load in an accident. This
could result in serious or even fatal injuries
to the secured child in the event of an acci-
dent, heavy braking or a sudden change in
direction.
For this reason, have child restraint sys-
tems and their anchorages which have
been damaged or subjected to a load in an
accident checked immediately at a quali-
fied specialist workshop.
X Position the backrest vertically
(Y page 81). The anchor fittings on the outer seats in the

stered lining.

TopTether
TopTether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear seat. It helps reduce
the risk of injury even further.

Risk of injury
Do not secure the TopTether hook* to the
loop underneath the TopTether anchorage
if you are securing a child restraint system
in the 3rd row of seats*. The child restraint
system is then not secure. An incorrectly
fitted child restraint system cannot perform
its intended protective function in the event
of an accident, and could even lead to inju-
ries. Safety

Seat belts
94 Seat belts
Wearing seat belts
Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with the vehicle interior. G
Risk of injury
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its inten-
ded protective function. Under certain cir-
cumstances this could cause severe or
even fatal injuries.
Make sure that all occupants – in particular,
pregnant women – wear their seat belt cor-
rectly at all times.
R The seat belt must pass closely over your
body and must not be twisted. You
should therefore avoid wearing bulky
clothing (e.g. a winter coat). The shoulder
belt section must be routed across the
middle of your shoulder – on no account
across your neck or under your arm – and
pulled tight against your upper body. The
lap belt must always pass across your lap
as low down as possible, i.e. over your hip joints – not across your abdomen. If
necessary, push down the belt strap
slightly and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
or fragile objects, especially if these are
located on or in your clothing, e.g. spec-
tacles, pencils, keys, etc. The seat belt
strap could be damaged and tear in an
accident and you or other vehicle occu-
pants could be injured.
R Only one person should use each seat
belt at any one time. Children must never
travel sitting on the lap of other occu-
pants. It would not be possible to restrain
the child in the event of a sudden change
in direction, braking or an accident. This
could result in severe or even fatal inju-
ries to the child and other occupants.
R Persons less than 1.50 m tall cannot
wear the seat belts correctly. For this
reason, secure persons less than 1.50 m
tall in specially designed, suitable
restraint systems.
R Children less than 1.50 m tall or under
12 years of age cannot wear the seat
belts properly. Therefore, always secure
these children in suitable child restraint systems on suitable vehicle seats. You
can find more information under "Chil-
dren in the vehicle" in the "Safety" sec-
tion of the Owner's Manual. Follow the
manufacturer's installation instructions
when fitting the child restraint system.
R Do not secure any objects with a seat belt
if the seat belt is also being used by one
of the vehicle's occupants. G
Risk of injury
The seat belt does not offer the intended
level of protection unless the backrest is
almost vertical. Under certain circumstan-
ces this could cause severe or even fatal
injuries.
Before starting a journey, make sure that
the seat is properly adjusted and that the
backrest is almost vertical. G
Risk of injury
A dirty or damaged seat belt or a seat belt
that has been subjected to a load in an
accident or modified no longer offers the
intended level of protection. Under certain
circumstances this could cause severe or
even fatal injuries. Controls

key* with you when leaving the vehicle, even if you are only leaving it for a short
time.

Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. The children could:
R be seriously or even fatally injured on
parts of the vehicle
R be seriously or even fatally injured by
prolonged exposure to extremely high or
extremely low temperatures

Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. i
If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance.
