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 warn-ing tone sounds. A warning tone also soundswith increasing intensity for 60 seconds oruntil the driver or front passenger have fas-tened their seat belts.
If the driver or front passenger unfasten theirseat belts during the journey, the seat beltwarning is activated again.
Air bags
Introduction
The installation point of an airbag can be rec-ognized by the AIRBAG marking.
An airbag complements the correctly fastenedseat belt. It is no substitute for the seat belt.When deployed, an airbag can increase theprotection provided for the respective vehicleoccupant.
Not all airbags are deployed in an accident.The various airbags work independently ofeach other (Ypage 50).
However, no system available today can com-pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injurycaused by an airbag due to the high speed atwhich the airbag must be deployed.
Important safety notes
GWARNING
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:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the
greatest possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
All vehicle occupants must observe the follow-ing notes to avoid risks posed by the airbagwhen it deploys.
RAdjust the seats properly before beginningyour journey. Always make sure that theseat is in an almost upright position. Thecenter of the head restraint must supportthe head at about eye level.
RMove the driver's and front-passenger seatsas far back as possible. The driver's seatposition must allow the vehicle to be drivensafely.
ROnly hold the steering wheel on the outside.This allows the airbag to be fully deployed.
RAlways lean against the backrest while driv-ing. Do not lean forward or lean against thedoor or side window. You may otherwise bein the deployment area of the airbags.
RAlways keep your feet in the footwell infront of the seat. Do not put your feet on thedashboard, for example. Your feet may oth-erwise be in the deployment area of the air-bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraintsystems. Up to this height, the seat beltcannot be worn correctly.
If a child is traveling in your vehicle, alsoobserve the following notes:
RAlways secure children under twelve yearsof age and less than 5 ft (1.50 m) tall in suit-able child restraint systems.
RSecure a child to the front-passenger seatonly when the front-passenger front airbagis deactivated, and then only in a rearward-facing child restraint system. The front-passenger front airbag is deactivated whenthe PASSENGER AIR BAG OFF indicatorlamp is lit continuously (Ypage 39).
RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 46) and on "Childrenin the vehicle" (Ypage 53) in addition tothe child restraint system manufacturer'sinstallation and operating instructions.
Objects in the vehicle interior may restrictthe airbag from functioning correctly.Toavoid risks resulting from the speed of the air-bag as it deploys, vehicle occupants mustensure the following points.
Occupant safety43
Safety

Before commencing your journey, ensure that:
Rthere are no people, animals or objectsbetween the vehicle occupants and an air-bag
Rthere are no objects between the seat, doorand B-pillar
Rno accessories, such as cup holders, areattached to the vehicle within the deploy-ment area of an airbag, e.g. to doors or sidewindows
Rno heavy, sharp-edged or fragile objects arein the pockets of your clothing. Store suchobjects in a suitable place
GWARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
GWARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or
door paneling carried out at a qualified spe-
cialist workshop.
Front air bags
!Do not place heavy objects on the front-passenger seat. This could cause the sys-tem to identify the seat as being occupied.In the event of an accident, the restraintsystems on the front-passenger side may betriggered and have to be replaced.
Driver's air bagCdeploys in front of thesteering wheel. Front-passenger front airbagDdeploys in front of and above the glovebox.
When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the driver's and front-passengerseats.
The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Ypage 39).
The front-passenger front air bag will onlydeploy if:
Rthe system, based on the OCS weight sen-sor readings, detects that the front-passenger seat is occupied (Ypage 46).The PASSENGER AIR BAG OFF indicatorlamp is not lit (Ypage 46)
Rthe restraint system control unit predicts ahigh accident severity
Knee bags
Driver's knee bagCdeploys under the steer-ing column and front-passenger knee bagDunder the glove box. The driver's and front-passenger knee bags are triggered togetherwith the front air bags.
44Occupant safety
Safety

The driver's and front-passenger knee bagsoffer additional thigh, knee and lower leg pro-tection.
Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they
are designed to do. In addition, the opera-
tion of the occupant classification system
(OCS) could be adversely affected. This
poses an increased risk of injury or even
fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Side impact air bagsCdeploy next to theouter bolster of the seat backrest.
When deployed, the side impact air bag offersadditional thorax protection. However, it doesnot protect the:
Rhead
Rneck
Rarms
If the restraint system control unit detects aside impact, the side impact air bag isdeployed on the side on which the impactoccurs.
The side impact air bag on the front passengerside deploys under the following conditions:
Rthe OCS system detects that the frontpassenger seat is occupied or
Rthe seat belt buckle tongue is engaged inthe belt buckle of the front passenger seat
If the belt tongue is engaged in the beltbuckle, the side impact air bag on the frontpassenger side deploys if an appropriate acci-dent situation occurs. In this case, deploymentis independent of whether the front passengerseat is occupied or not.
Head air bags
Head bagsCdeploy in the area of the sidewindows at the front.
When deployed, the head bag enhances thelevel of protection for the head. However, itdoes not protect the:
Rchest
Rarms
If the restraint system control unit detects aside impact, the head bag is deployed on theside on which the impact occurs.
If the system determines that they can offeradditional protection to that provided by theseat belt, a head bag may be deployed in otheraccident situations (Ypage 50).
The head bag on the front-passenger sidedeploys under the following conditions:
Rthe OCS system detects that the front-passenger seat is occupied or
Rthe seat belt buckle tongue is engaged inthe belt buckle of the front-passenger seat
If the belt tongue is engaged in the beltbuckle, the head bag on the front-passengerside deploys if an appropriate accident situa-tion occurs. In this case, deployment is inde-pendent of whether the front-passenger seat isoccupied or not.

minor deformation. This is the case if, forexample, very rigid vehicle parts such as longi-tudinal body members are hit, and sufficientdeceleration occurs as a result.
If the restraint system control unit detects aside impact or if the vehicle rolls over, theapplicable components of the restraint systemare deployed independently of each otherdepending on the apparent type of accident.
RSide impact air bag on the side of impact,independently of the Emergency TensioningDevice and the use of the seat belt on thedriver's seat
The side impact air bag on the frontpassenger side deploys under the followingconditions:
-the OCS system detects that the frontpassenger seat is occupied or
-the seat belt buckle tongue is engaged inthe belt buckle of the front passengerseat
RHead bag on the side of impact, independ-ently of the use of the seat belt and inde-pendently of whether the front-passengerseat is occupied
REmergency Tensioning Devices, if the sys-tem determines that deployment can offeradditional protection in this situation
RHead bags on the driver's and front-passenger side in certain situations whenthe vehicle rolls over, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt
iNot all air bags are deployed in an acci-dent. The different air bag systems workindependently of each other.
How the air bag system works is determinedby the severity of the accident detected,especially the vehicle deceleration or accel-eration and the apparent type of accident:
RHead-on collision
RSide impact
RRollover
NECK-PRO head restraints
Important safety notes
GWARNING
The function of the head restraint may be
impaired if you:
Rattach objects such as coat hangers to
the head restraints, for example
Ruse head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the
event of an accident. In addition, objects
attached to the head restraints could endan-
ger other vehicle occupants. There is an
increased risk of injury.
Do not attach any objects to the head
restraints and do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraints reduce the likeli-hood of head and chest injuries. The NECK-PRO head restraints on the driver's and front-passenger seats are moved forwards andupwards in the event of a rear-end collision ofa certain severity. This provides better headsupport.
If the NECK-PRO head restraints have beentriggered in an accident, you must reset theNECK-PRO head restraints on the driver’s andfront-passenger seat (Ypage 53). Other-wise, the additional protection will not beavailable in the event of another rear-end colli-sion. You can recognize when NECK-PRO headrestraints have been triggered by the fact thatthey have moved forwards and can no longerbe adjusted.
Mercedes-Benz recommends that you havethe NECK-PRO head restraints checked forfunctionality at a qualified specialist workshopafter a rear-end collision.

Safety

"Digital Vehicle Key" function is activated via
Mercedes me connect. Never leave children
unsupervised in the vehicle.
The seats can still be adjusted when there isno 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.
When adjusting a seat, make sure that no
one has any body parts in the sweep of the
seat.
GWARNING
If the driver's seat is not engaged, it could
move forwards as far as the next catch dur-
ing movement such as braking or abrupt
changes of direction. As a result, you would
be pushed against your seat belt by the
unsecured driver's seat.
This could cause you to lose control of the
vehicle. The seat belt cannot protect as
intended and could result in additional
injury.
There is a risk of an accident and injury.
Before every journey, make sure that the
driver's seat is fully engaged.
Observe the safety notes on "Air bags"(Ypage 43) and "Children in the vehicle"(Ypage 53).
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
or other vehicle occupants could be trapped
and thereby injured. Children in particular
could accidentally press the electrical seat
adjustment 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
system.
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
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,
steering wheel and mirror and fasten your
seat belt before starting the engine.
