When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter coat.
R the seat belt is not twisted.
Only then can the forces which occur be
distributed over the area of the belt.
R the 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.
R the 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 usingthe shoulder section of the belt.
R the seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses,
store these in a suitable place.
R only one person is using a seat belt at atime.
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 seatbelt.
R objects 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 notes in the "Stowage options/compart-
ments" section for securing objects, luggage
or loads ( Ypage 258).Fastening seat belts
Observe the safety notes on the seat belt (Y page 42) and the notes on correct use of
seat belts ( Ypage 43).

section of the seat belt to tighten the belt
across your body.
In order to attach the child restraint system
securely in the vehicle, the seat belt on the
front-passenger seat is equipped with a spe-
cial seat belt retractor. Further information on
the "Special seat belt retractor"( Y page 58).

Seat belt adjustment
AMG vehicles: the "seat-belt adjustment"
function is not available.
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:
R the belt tongue is engaged in the buckle and
R the 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( Y page 207).
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants to
fasten their seat belts. It may light up contin- uously or flash. A warning tone may also
sound.
Regardless of whether the driver's and front
passenger seat belts have already been fas-
tened, the 7seat belt warning lamp lights
up for six seconds every time the engine is
started. If the doors are closed and the driver
or front passenger has not fastened his seat
belt, the 7seat belt warning lamp lights
up again after these six second s.As soon as
the driver and the front passenger both have their seat belts fastened or a door is opened
again, the 7seat belt warning lamp goes
out.
If the driver's seat belt is not fastened when
the engine is started, a warning tone will addi-
tionally sound. This warning tone switches off
after approximately six second s or once the
driver's seat belt is fastened.
Once a vehicle speed of 15 mph (25 km/h) is exceeded and the driver's or front-passenger seat belt is not fastened, a warning tone will
sound again. The warning tone will sound with increasing intensity for 60 seconds or until
the driver or front passenger have fastened
their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the belt warning
will be automatically activated once again.
iFurther information on the 7seat belt
warning lamp can be found under “Indica-
tor and warning lamps in the instrument
cluster, seat belt” ( Ypage 244).

remains lit, even
though the front-
passenger seat is occu-
pied by an adult or a

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 ®

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:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R on 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:
R the seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavorable position.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced: X Move 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 PRE-SAFE ®

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. Neverleave 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" ( Y page 46) and "Children in the vehicle"
( Y page 57).
GWARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control of
the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
GWARNING
If you adjust the seat height carelessly, you orother vehicle occupants could be trapped andthereby 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 head restraints are not installed and adjus-
ted correctly, they cannot provide protection
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
