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).

All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
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).

XMake sure that the entire base of the child restraint system rests on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system must lie as flat as pos-
sible against the backrest of the front-passenger seat. If nec-
essary, adjust the position of the front-passenger seat.
XWhen installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight using the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the
child restraint system. If necessary, adjust the head restraint
accordingly.
XMake sure that no objects are applying additional weight onto
the seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off, do
not install a child restraint system on the front-passenger seat.
It is recommended that you install the child restraint system on
a suitable rear seat.

PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE®
takes pre-emptive measures to protect the
vehicle occupants.
Important safety notes
!Make sure that there are no objects in the
footwell or behind the seats. There is a dan-
ger that the seats and/or objects could be
damaged when PRE-SAFE
®is activated.
Although your vehicle is equipped with PRE-
SAFE
®, the possibility of injury in the event of
an accident cannot be ruled out. Always
adapt your driving style to suit the prevailing
road and weather conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
Function
PRE-SAFE®intervenes:
Rin emergency braking situations, e.g. when
BAS is activated
Rin critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
Ron vehicles with the Driving Assistance
package: if BAS PLUS intervenes power-
fully or the radar sensor system detects an
imminent danger of collision in certain sit-
uations PRE-SAFE
®takes the following measures
depending on the hazardous situation detec-
ted:
Rthe front seat belts are pre-tensioned.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. The panorama roof with
power tilt/sliding panel is completely
closed.
Rvehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavorable position.
Rvehicles with a multicontour seat: the air
pressure in the side bolsters of the seat
backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats, the air pressure in the side
bolsters is reduced again. All settings made
by PRE-SAFE
®can then be reversed.
If the seat belt pre-tensioning is not reduced:
XMove the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PR

E-SAFE®convenience function. You
will find information on the convenience func-
tion under "Belt adjustment" (
Ypage 49).
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the elec-
trically adjustable steering wheel is raised

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.

Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
Rclean the seat covers as recommended;
see "Interior care".
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.
!Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam- aged.
iIt is not possible to remove the head
res traints fro
m the front seats. The rear-
compartment head restraints, however,
can be removed (
Ypage 112).
