Safety belts
Seats with safety belt
The vehicle has four seats, each of which is
equipped with a safety belt.
Notes
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
One person per safety belt
Never
allow more than one person to wear
a single safety belt. Never allow infants or small
children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies low
around the hips in the lap area and does not
press on the abdomen. Otherwise, the belt can
slip over the hips in the lap area in a frontal im‐
pact and injure the abdomen.
The safety belt must not lie across the neck, rub
on sharp edges, be routed over solid or breaka‐
ble objects, or be pinched.◀
Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀ Buckling the belt
Make sure you hear the latch plate engage in the
belt buckle.
Unbuckling the belt
1.
Hold the belt firmly.
2. Press the red button in the belt buckle.
3. Guide the belt back into its reel.
Safety belt reminder for the driver's and
front passenger seat The indicator lamp flashes or lights up
and a signal sounds. Make sure that the
safety belts are positioned correctly.
The safety belt reminder is active at speeds
above approx. 5 mph/8 km/h. It can also be ac‐
tivated if objects are placed on the front pas‐
senger seat.
Damage to safety belts
In the case of strain caused by accidents or
damage:
Have the safety belts, including the safety belt
tensioners, replaced and have the belt anchors
checked.
Checking and replacing safety belts
Have the work performed only by your
service center; otherwise, it cannot be ensured
that this safety feature will function properly.◀ Seite 56

▷
Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.
▷ Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.
▷ Do not hang pieces of clothing, such as jack‐
ets, over the backrests.
▷ Make sure that occupants keep their heads
away from the side airbag; otherwise, inju‐
ries can occur if the airbags are deployed.
▷ Do not remove the airbag restraint system.
▷ Do not remove the steering wheel.
▷ Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.
▷ Never modify either the individual compo‐
nents
or the wiring in the airbag system. This
also applies to steering wheel covers, the
dashboard, and the seats.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term

and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors. Functional readiness of the airbag
system
When

the ignition is switch on, the warn‐
ing lamp in the instrument cluster lights
up briefly and thereby indicates the op‐
erational readiness of the entire airbag system
and the belt tensioner.
Airbag system malfunctioning
▷ In radio ready state, the warning lamp does
not come on.
▷ The warning lamp lights up continuously.
When there is a malfunction, have the air‐
bag system checked immediately
When there is a malfunction, have the airbag
system checked immediately; otherwise, there
is

a risk that the system does not function as ex‐
pected in the event of an accident despite cor‐
responding severity of the accident.◀
Automatic deactivation of the front
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body.
The front, knee, and side airbag on the front
passenger side are activated or deactivated ac‐
cordingly.
Leave feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀

tor lamp for the front passenger airbags lights
up.
In this case, change the sitting position so that
the front passenger airbags are activated and
the indicator lamp goes out.
If it is not possible to activate the airbags, have
the person sit in the rear.
To make sure that the occupied seat cushion
can be evaluated correctly
▷
Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐
less they are specifically recommended by
the manufacturer of your vehicle.
▷ Do not place any objects on the front pas‐
senger seat.
▷ Do not place objects under the seat that
could press against the seat from below.
Indicator lamp for the front passenger
airbags The indicator lamp for the front passenger air‐
bags indicates the operating state of the front
passenger airbags.
The lamp indicates whether the airbags are ac‐
tivated or deactivated.
▷The indicator lamp lights up
when a child who is properly
seated in a child restraint fix‐
ing system intended for that
purpose is detected on the
seat
or the seat is empty. The
airbags on the front passen‐
ger side are not activated.
▷ The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The airbags on the front passenger side are ac‐
tivated.
The system generally detects children seated in
a child seat, especially in the child seats that
were required by NHTSA when the vehicle was
manufactured.

After installing a child seat, make
sure that the indicator lamp for the front pas‐
senger airbags lights up. This indicates that the
child seat has been detected and the front pas‐
senger airbags are not activated.
Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on the
position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Control
Display.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.
1. Move the respective seat forward all the
way.
2. Move the respective seat forward again. It
moves forward briefly.
3. Readjust the seat to the desired position.
The calibration procedure is completed when
the
message on the Control Display disappears.
If the message continues to be displayed, repeat
the calibration.
If the message does not disappear after a repeat
calibration, have the system checked as soon as
possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury or
damage to objects.◀ Seite 90
