For maximum safety when adjusting the
seating position, please observe the
following:
Never try to adjust your seat while
driving the vehicle. The seat could
respond with an unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
Never ride with the backrest reclined to
an extreme angle (especially important
for the passenger to remember). If you
do so, there is a risk that you will slide
under the safety belt in an accident,
thus reducing the protection provided
by the safety belt.<
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line.
For long-distance driving, you may wish
to increase the backrest tilt-angle
slightly to reduce muscular tension.
You should be able to grasp the steer-
ing wheel at its highest point with your
arms slightly bent.
1 Backward/Forward adjustment
2 Cushion height
3 Backrest angle
Adjust the head restraint manually.
Move the seat backward only if
the backrest is first locked into
place. Whenever the backrest has been
flipped forward, moved back and sub-
sequently folded back into place, it
cannot lock, which can damage the
back of the backrest and the rear trim
panel.
Do not move a seat whose backrest has
been tilted too far back, otherwise, the
back of the backrest and the rear trim
panel could be damaged.<

Head restraints Seat backrest Belt guideAdjustments Upward: by pulling.
Downward: unlock by first pressing the
button located on the right under the
leather (arrow 1).
Head restraints reduce the risk
of spinal injury in the event of an
accident.
Adjust the head restraint so that its
center is approximately level with your
ears.<520de016
To unlockPull on the outermost edge of the strap
and tip the backrest forward.
The straps are located on the outer
sides of the backrests. On the passen-
ger seat straps are also located on the
inner side of the backrest.
Lock both backrests while driving,
otherwise there is a danger of an
unexpected movement causing an
accident.
Do not use the strap as a holder, e. g.
for newspapers or other items. This
could cause the backrests to unlock.<520de098
The strap for the belt guide can be
opened: release the push button.
Should it be necessary, this can relieve
the load or the access to the equipment
in the rear well.
For further information regarding load-
ing, refer to page 81.
Before each trip, insert the safety
belt into the strap for the belt
guide, otherwise, it will not hold
securely and become ineffective due
to a loosely worn safety belt.<520de099

Adjusting the steering wheel
Mirrors
Press button: set the steering wheel
vertical to the seating position.
Do not adjust the steering wheel
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected movement.<520de118
Exterior mirrors1 Switch for 4-way adjustment
2 Selection switch for changing
between mirrors, switch either all the
way to the left or the right 520de018
You can also adjust the mirrors manu-
ally by pressing against the outer edges
of their lenses.
When estimating the distance be-
tween yourself and other traffic,
bear in mind that the objects reflected
in the mirror are closer than they ap-
pear. This means that estimating of the
distance to following traffic should not
be regarded as precise.
