Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In the
interaction with the safety belts, the head
restraints and the airbags, the seat position
plays an important role in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the fol-
lowing section.
For additional information on transporting chil-
dren safely, refer to page55.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 o'clock and 3 o'clock positions, to mini-
mize the risk of injuries to your hands and arms
in the event of airbag deployment.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly
and does not rest feet or legs on the instrument
panel, otherwise leg injuries can occur if the
front airbags are triggered.
Make sure that occupants do not rest their head
on the side or head airbags, otherwise injuries
can occur if the airbags are triggered.<
Even if you adhere to all the instructions, inju-
ries resulting from contact with airbags cannot
be fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page96.
Head restraints
A correctly adjusted head restraint reduces the
risk of spinal injury in the event of an accident.
Adjust the head restraint so that its center
is approx. at ear level. Otherwise there is
increased danger of injury in the event of an
accident.<
Head restraints, refer to page48.
Safety belts
Before every drive, make sure that safety belts
are being worn at all of the occupied seats. Air-
bags complement the safety belt as an addi-
tional safety device, but they do not represent a
substitute.
Your vehicle is provided with five seats, which
are all equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt lies low around the
hips in the lap area and does not press on the
abdomen. The safety belt may not lie across the
neck, rub on sharp edges, be routed over solid
or breakable objects or be pinched. Wear the
safety belt without twisting, snugly across the
lap and shoulders, as close to the body as pos-
sible. Otherwise the belt can slip over the hips
in the lap area in a frontal impact and injure the
abdomen. Avoid wearing clothing that prevents
the belt from fitting properly and pull the belt in
the upper body area periodically to readjust the
tension, in order to avoid a reduction in the
restraint of the safety belt.
Sports Wagon: if the center safety belt in the
rear is used, the larger backrest half must be
locked, refer to page120, otherwise the middle
safety belt has no restraining action.<
Safety belts, refer to page50.

Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

Cruise control*
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi-
cle and cause an accident.<
