pants are always wearing the seat belt cor-
rectly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
Rthe seat belt tongue is only inserted to thebelt buckle belonging to that seat.
Rthe seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
Rthe seat belt is not twisted.
Only then can the forces which occur be
distributed over the area of the belt.
Rthe shoulder section of the belt is always
routed across the center of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be
routed under your arm. Where possible,
adjust the seat belt to the appropriate
height.
Rthe lap belt passes tightly and as low down
as possible across your lap.
The lap belt must always be routed across
your hip joints and not across your abdo-
men. This applies particularly to pregnant
women. If necessary, push the lap belt
down to your hip joint and pull it tight using
the shoulder section of the belt.
Rthe seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses,
store these in a suitable place.
Ronly one person is using a seat belt at a
time.
Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat
belt.
Robjects are never secured with a seat belt if the seat belt is also being used by one of the
vehicle's occupants.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects,
luggage or loads (
Ypage 340).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(
Ypage 46) and the notes on correct use of
seat belts (
Ypage 47).

vehicle. Further information can be found
under "Special seat belt retractor"
(
Ypage 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.

Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
Rthe belt tongue is engaged in the buckle
and
Rthe ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(
Ypage 286).

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The seats can still be adjusted when there is
no SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 50) and "Children in the Vehicle"
(
Ypage 61).
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.

Rdo not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools. The seats should only be occupied by
passengers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
