Fastening and adjusting seat belts
Observe the safety notes on seat belts
(Y page
48) and the notes on the correct use
of the seat belt (Y page 49). Basic diagram
X Adjust the seat (Y page
87).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt out smoothly from the belt
outlet and engage belt tongue ; into belt
buckle :.
The shoulder section of the belt must
always be routed across the center of the
shoulder. If necessary, adjust the belt out-
let.
X If necessary, pull upwards on the seat belt
in front of your chest so that the belt sits
tightly across your body.
The shoulder section of the belt must always
be routed across the center of the shoulder. If
necessary, adjust the belt outlet. X To raise: slide the belt outlet upwards.
The belt outlet engages in a number of dif-
ferent positions.
X To lower: slide the belt outlet downwards
while pressing belt outlet release =.
X Let go of belt outlet release = in the
desired position and make sure that the belt
outlet engages.
All seat belts in the vehicle, with the exception
of the driver's seat belt, are equipped with a
child seat lock, to which a child restraint sys-
tem can be secured safely. You can find fur-
ther information under "Child seat lock"
(Y page

61). Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the
belt back.
Belt warning for drivers and co-drivers The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts cor-
rectly. It may light up continuously or flash. In
addition, there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 7 seat belt
warning lamp lights up for six seconds each
time the engine is started. If the front doors
are closed and the driver's or front-passenger
seat belt has not been fastened, the 7 seat
belt warning lamp lights up again after the six
seconds. As soon as the driver's and front-
passenger seat belts are fastened or a front
door is opened again, the 7 seat belt warn-
ing lamp goes out.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the driver's
seat belt is fastened.
If the vehicle's speed exceeds

15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warn-
ing tone sounds. A warning tone also sounds
with increasing intensity for 60 seconds or
until the driver or front passenger have fas-
tened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again. 50
