Driver’s and co-driver’s seatsWarning
G
Only adjust the seats when the vehicle is
stationary and the handbrake is applied. You
could otherwise lose control of the vehicle
as a result of the seat moving and cause an
accident.Warning
G
Make sure that nobody can become trapped
as the seat is adjusted. Never place your
hands under the seat or near to moving
parts.
Your seat must be adjusted in such a way
that you can wear the seat belt correctly
(\2page 27).
Observe the following points:
\4Position the backrest as vertically as
possible and sit upright.
\4Avoid seat positions that do not allow
the seat belt to be routed correctly. The
shoulder section of the seat belt must
be routed across the middle of your
shoulder and must fit closely across
your chest. The lap section of the belt
must be routed as low as possible
across your pelvic area, i.e. across your
hip joints. Never drive with the backrest
tilted too far back.
\4Your arms should be slightly bent when
you are holding the steering wheel.
\4The distance from the pedals should be
such that you can depress them fully.
\4Adjust the head restraint in such a way
that the upper edge of the head restraint
is level with your head.
\4Make sure that you hear the seat en-
gage. Otherwise, the seat is not correct-
ly locked in place.
Injuries may be caused if these notes are
not observed.Warning
G
Avoid seat positions in which you cannot
wear your seat belt correctly. They are a
safety hazard and must therefore be
avoided.

tated by 180° to be opposite of the direc-
tion of travel.The seats engage in the direction of travel
or opposite the direction of travel as well
as at 50° pointing towards the exit.
!
When rotating the seats, make sure the-
re is sufficient space. If necessary, move
the seat fore or aft to avoid colliding with
adjacent add-on parts.
Fold the handbrake lever down as far as it
will go. You could otherwise damage the
handbrake or the handbrake lever.
i
Move the co-driver’s seat forward as far
as it will go before rotating it (\2page 69).

sufficient clearance for turning and ad-
justing the driver’s seat (\2page 76).

stationary and the handbrake is applied. You
could otherwise lose control of the vehicle
as a result of the seat moving and cause an
accident.Warning
G
The driver’s and co-driver’s seat must be ad-
justed and properly engaged in the direction
of travel for driving. Otherwise you will not
be able to operate the vehicle safely.The restraint systems in your vehicle will
only function as intended when the driver’s
and co-driver’s seat are engaged in the di-
rection of travel.

Only adjust the steering wheel when the ve-
hicle is stationary. Only drive with the steer-
ing wheel locked in position.
An incorrectly secured steering wheel could
make it more difficult to steer the vehicle
safely, since the height and fore-and-aft ad-
justment could move out of position when
the steering wheel is turned. You could lose
control of the vehicle as a result, cause an
accident and injure yourself and others.Warning

Never leave children unsupervised in the ve-
hicle. They could become trapped if they try
to adjust the steering column.
