Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Y
page 46) and the notes on correct use of seat
belts (Y page 47). Basic illustration
X Adjust the seat (Y page 97).
The seat backrest must be in an almost
upright position.
X Pull the seat belt smoothly from the belt outlet
and engage belt tongue 0044into belt
buckle 0043.
The seat belt on the driver’s seat and the
front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(Y page 48).
X If necessary, pull up on the shoulder section
of the seat belt to tighten the belt across your
body.
The shoulder section of the seat belt must
always be routed across the center of the shoul- der. Adjust the belt outlet if necessary.

The belt outlet will engage in various posi-
tions.
X To lower: hold belt outlet release 0087and slide
the belt outlet down.
X Let go of belt outlet release 0087in the desired
position and make sure that the belt outlet
engages.
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" (Y page 60).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. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Seat belt adjustment The belt adjustment is a convenience function
integrated into PRE-SAFE
®
. With this function,
the driver's and front-passenger seat belts are
adjusted to the upper body of the vehicle occu-
pant.
The seat belt strap will slightly tighten if:
R the belt tongue is inserted into the buckle and
R the ignition is switched on
The seat belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not
grab hold of the seat belt.
The belt adjustment can be switched on and off using the on-board computer (Y page 240).
Belt warning for the driver and front
passenger The
0076 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu-
pants must wear their seat belts. 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 0076seat belt warn-
ing 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 0076seat 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 0076seat belt warning lamp goes out.
If the driver's seat belt is not fastened after the engine is started, an additional warning tone will
sound. The warning tone switches off after six 48

0050Solutions The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son of a stature corre-
sponding to that of an
adult. The classification of the person on the front-passenger seat is incor-
rect.
X Make sure the conditions for a correct classification of the person
on the front-passenger seat are met (Y page 52).
X If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
X Have OCS checked as soon as possible at an authorized Mercedes-
Benz Center. The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seatis:
R unoccupied
R occupied by the
weight of a child up to
twelve months old in achild restraint system OCS is malfunctioning.
X Make sure there is nothing between the seat cushion and the child
seat.
X Make 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 possible
against the backrest of the front-passenger seat. If necessary,
adjust the position of the front-passenger seat.
X When 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.
X Check 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 accord-
ingly.
X Make sure that no objects are applying additional weight onto the
seat.
X If the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install a child restraint system on the front-passenger seat. It is recom-
mended that you install the child restraint system on a suitable rear
seat.
X Have OCS checked as soon as possible at an authorized Mercedes-
Benz Center. Deployment of Emergency Tensioning

®
PLUS (anticipatory occu-
pant protection system PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance PLUS package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene if the vehi-
cle is backing up.
When driving, or when parking or exiting a park-
ing space using Active Parking Assist, PRE-
SAFE ®
PLUS will not apply the brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision. PRE-SAFE
®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned.
R if the radar sensor system detects that a rear-
end collision is imminent:
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta- tionary.
- the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is can-
celed:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if Active Distance Assist DISTRONIC indicates
an intention to intervene
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R the hazard warning lamps are switched on
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised when
the driver's door is opened
R the engine is switched off and the fuel supply
is cut off
R vehicles with Mercedes me connect: auto-
matic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install Children in the vehicle
