Seat position9 Warning
Only drive with the seat correctly
adjusted.
9 Danger
Do not sit nearer than 25 cm from
the steering wheel, to permit safe
airbag deployment.
9 Warning
Never adjust seats while driving as
they could move uncontrollably.
● Sit with buttocks as far back against the backrest as possible.
Adjust the distance between the
seat and the pedals so that legs
are slightly angled when fully
pressing the pedals. Slide the
front passenger seat as far back
as possible.
● Set seat height high enough to have a clear field of vision on all
sides and of all display
instruments. There should be at
least one hand of clearance
between head and the roof
frame. Your thighs should rest
lightly on the seat without
pressing into it.
● Sit with shoulders as far back against the backrest as possible.
Set the backrest rake so that it is possible to easily reach the
steering wheel with arms slightly
bent. Maintain contact between
shoulders and the backrest when
turning the steering wheel. Do
not angle the backrest too far
back. We recommend a
maximum rake of approx. 25°.
● Adjust seat and steering wheel in
a way that the wrist rests on top
of the steering wheel while the
arm is fully extended and
shoulders on the backrest.
● Adjust the steering wheel 3 82.
● Adjust the head restraint 3 35.
● Adjust the height of the seat belt 3 46.
● Adjust the thigh support so that there is a space approx. two
fingers wide between the edge of the seat and the hollow of the
knee.
● Adjust the lumbar support so that
it supports the natural shape of the spine.

Seats, restraints45Removing the adapterUnlock the adapter by turning the
ignition key anticlockwise in the lock.
The adapter is unlocked when the red mark is visible.
Push the adapter rearward and
remove.Seat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle holding the occupants in
the sitting position. Therefore the risk
of injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 55.
Periodically check all parts of the belt
system for damage, pollution and
proper functionality.
Have damaged components
replaced. After an accident, have the
belts and triggered belt pretensioners replaced by a workshop.
Note
Make sure that the belts are not
damaged by shoes or sharp-edged
objects or trapped. Prevent dirt from
getting into the belt retractors.
Seat belt reminder X 3 95.
Belt force limiters
Stress on the body is reduced by the
gradual release of the belt during a
collision.
Belt pretensioners
In the event of a head-on or rear-end collision of a certain severity, the front
seat belts are tightened.
Page 48 of 251

46Seats, restraints9Warning
Incorrect handling (e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
Deployment of the belt pretensioners
is indicated by continuous illumination
of control indicator v 3 95.
Triggered belt pretensioners must be replaced by a workshop. Belt
pretensioners can only be triggered
once.
Note
Do not affix or install accessories or
other objects that may interfere with
the operation of the belt
pretensioners. Do not make any
modifications to belt pretensioner components as this will invalidate
the vehicle type approval.
Three-point seat belt
Fasten
Withdraw the belt from the retractor,
guide it untwisted across the body
and insert the latch plate into the
buckle. Tighten the lap belt regularly
whilst driving by pulling the shoulder
belt.
Loose or bulky clothing prevents the

objects such as handbags or mobile
phones between the belt and your body.

your clothing.
