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. Where possible,
adjust the seat belt to the appropriate
height.
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 using the 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 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.
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 "Loading guidelines" for securing objects,
luggage or loads (Y page 292). Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y
page 44) and the notes on correct use of
seat belts (Y page 45).
If the center rear seat belt is being used, also

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:
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. Occupant safety

Belt warning for the driver and front
passenger The
0076 seat belt warning lamp in the instru-
ment cluster is a reminder that all occupants
must fasten 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
warning lamp lights up for six seconds each
time the engine is started. If, after
six seconds, the driver or front-passenger
seat belt has not been fastened and the doors are closed, the 0076seat belt warning lamp
lights up again. 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. This warning tone stops after six seconds or when 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
warning tone sounds. The warning tone
sounds 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 seat belt
warning is activated again.
i For more information on the
0076seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (Y page 280). Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (Y page 57).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely. 48

BAG OFF indicator
lamp lights up and
remains lit, even
though the front-
passenger seat is occu-
pied by an adult or a
person of a stature cor-
responding to that of an
adult. The classification of the person on the front-passenger seat is
incorrect.
X Make sure the conditions for a correct classification of the per-
son 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
seat is:
R unoccupied
R occupied by the
weight of a child up
to 12 months old in a
child restraint sys-
tem 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 pos- sible against the backrest of the front-passenger seat. If nec-
essary, 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
accordingly.
X Make sure that no objects are applying additional weight onto
the seat.
X If 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 restraint system on a
suitable rear seat.
X Have OCS checked as soon as possible at an authorized
Mercedes-Benz Center. 56

®
PLUS (anticipatory occu-
pant protection system PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance 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 hazard-
ous situations, 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 interven-
tion of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene if the
vehicle is backing up. PRE-SAFE
®
PLUS does not perform braking
actions while the vehicle is in motion or when Parking Guidance is active.
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 meas-
ures 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 vehi-
cle is stationary.
- the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is
canceled:
R if the accelerator pedal is depressed when
a gear is engaged
R if the risk of a collision passes or is no lon-
ger detected
R if DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting 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 activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered Occupant safety
