Seat belts
Rear seat belts fastened display* Fig. 10
Instrument panel: left rear seat occu-
pied and corr esponding seat belt f
astened dis-
play. Depending on the model version, when the
ignition is s
wit

ched on, the seat belt status
display ››› Fig. 10
on the instrument panel in-
forms the driver whether the passengers in
the rear seats have fastened their seat belts.
It indicates that the corresponding seat
is empty.
Indicates that the seat is occupied and
the occupant is wearing the seat belt.
The seat belt status flashes for a maximum of
30 seconds when a seat belt in the rear seats
is unfastened while the vehicle is in motion. An
audible warning will also be heard if the vehi-
cle is travelling at over 25 km/h (15 mph).
If a seat belt is fastened or unfastened while
driving in some of the rear seats, the seat belt
]
i status is displayed for approximately 30 sec-
onds. The indication can be hidden by press-
ing the E

 button on the dash panel.
The protective function of seat
belts Fig. 11
Drivers with properly worn seat belts
will not be thr o

wn forward in the event of sud-
den braking. Properly worn seat belts hold the occupants
in the pr
oper position. They al

so help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of
the belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas-
sive safety features (such as the airbag sys- tem) are designed to absorb the kinetic ener-
gy rel

eased in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driving
around the corner".
Ensure that your passengers wear their seat
belts as well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury and
improving the chances of survival when in-
volved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, overturns or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
