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 page54.
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 airbag is triggered.
Make sure that occupants do not rest their head
on the side or head airbag, 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 page94.
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 middle safety belt in the
rear is used, the larger seatback half must be
locked, refer to page117, otherwise the middle
safety belt has no restraining action.<
Safety belts, refer to page49.

control sequence each time you press the but-
ton.
To switch off: press the button longer.
The highest position with three LEDs is
used for rapid cooling, e.g. when the vehi-
cle has gotten heated up. After a short time, the
system is automatically switched down one
position in order to prevent excessive cooling.<
Active seat*
The seat cushion is actively varied by alter-
nately raising and lowering the right and left half
of the seat cushion. This reduces muscular ten-
sion and fatigue to help prevent lower back
pain.

up.
If you switch off the active seat, it can take up
to 1 minute before the two halves of the seat
cushion have returned to their initial position.
Mirrors
Exterior mirrors
The mirror on the passenger's side is
more curved than the driver's mirror.
Objects reflected in the mirror are closer than
they appear. Do not estimate the distance of
following traffic based on what you see in the
mirrors, otherwise there is an increased acci-
dent risk.<

Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance
over the familiar cruise control and is a welcome
relief from the constant adjustment of speed
that can accompany driving in traffic on free-
ways or other high-speed thoroughfares.

objects for a longer time, e. g. on infre-
quently traveled roads without a shoulder or
guard rails, or if the radar sensor is covered
with dirt, refer to page71
>When the speed is reduced to below
20 mph/30 km/h due to a traffic situation
The system deactivates automatically
