The QR code is secured in the fuel filler flap and

Elect
ronic control units are fitted in your vehicle.
Some of these are necessary forth e safe opera‐

driving (driver assis tance sy stems). In addition,
yo ur vehicle pr ovides com fort and enter tainment
functions, which are also made possible byelec‐

Elect ronic control units contain da tamemories
which cantemp orarily or permanently store

general, this information documents thest ate

sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tyre pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐

R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)

Re
stra int sy stem Pr
otection bythere stra int sy stem The
restra int sy stem includes thefo llowing com‐
ponents:
R Seat belt sy stem
R Airbags
R Child restra int sy stem
R Child seat securing sy stem
The restra int sy stem can reduce therisk of vehi‐
cle occupants coming into contact with parts of
th eve hicle's interior in theeve nt of an accident.
The restra int sy stem can also reduce thefo rc es
to which vehicle occupants are subjected in the
eve nt of an accident.
Only a seat belt which is worncor rectly can pro‐
vide the intended le vel of pr otection. Depending
on the de tected accident situation, seat belt ten‐
sioners and/or airbags supplement a cor rectly
wo rnseat belt. Seat belt tensioners and/or air‐
bags are not depl oyed in everyaccident. Fo
rth ere stra int sy stem toprov ide its full pr otec‐
tion, each occupant must obser vethefo llowing:
R Fasten the seat belt cor rectl y.
R Be in an almost up right position with their
back against the seat backrest.
R Sit with their feet resting on thefloor, if pos‐
sible.
R Alw ays secure persons under 1.50 m tall in
an additional restra int sy stem suitable for
Mercedes-Benz vehicles.
Ho wever,no sy stem available today can com‐
ple tely eliminate injuries and fata lities in every
accident situation. In particular, the seat belt
and airbag generally do not pr otect against
objects penetrating theve hicle from the outside.
The risk of an injury resulting from airbag
deployment also cannot be ruled out entirel y. Limited pr
otection from there stra int sy stem &
WARNING Risk of inju ryor death from
modifications tothere stra int sy stem
The restra int sy stem can no longer function
cor rectly af ter alterations ha vebeen made.
The restra int sy stem may then not pr otect
th eve hicle occupants as intended byfailing
in an accident or triggering unexpec tedly, for

Never alter the parts of there stra int
sy stem. #
Neverta mp er with the wiring or any
electronic component parts or their
software. If it is necessary
toadjust theve hicle toaccom‐
modate a person with disabilities, con tact a

Mercedes-Benz recommends that you on lyuse
driving aids which ha vebeen appr oved specifi‐

Re
stra int sy stem functionality When
the ignition is switched on, a self-test is
per form ed, during which the6 restra int sys‐
te m wa rning lamp lights up. It goes out no later
th an a few seconds af terth eve hicle is star ted.
The components of there stra int sy stem are then
functional. Malfunctioning

red in there stra int sys‐
te m if:
R the6 restra int sy stem warning lamp does
not light up when the ignition is switched on
R the6 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journey &
WARNING Risk of inju ryor fata l injury
due toa malfunction in there stra int sys‐
tem
If th ere stra int sy stem is malfunctioning,
re stra int sy stem components may be trig‐ ge
red unintentionally or might not be trig‐
ge red at all in theev ent of an accident. This
may af fect the seat belt tensioner or airbag,
fo rex ample. #
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu
nction of there stra int sy stem in an acci‐
dent How
there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
R Frontal impact
R Rear impact
R Side impact
R Onlyfor cer tain countries: rollo ver
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of th
e components of there stra int sy stem must
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measu red
af te r a collision has occur red do not play a deci‐
sive role in the deployment of an airbag. Nordo
th ey prov ide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, forex am‐
ple, this may result in suf ficiently high le vels of
ve hicle deceleration. Occupant saf

af te r an accident. Take this into account, partic‐
ularly if a seat belt tensioner is trig gered or an
airbag deplo yed.
If th e seat belt tensioners are trig gered or an air‐
bag is deplo yed, you will hear a bang, and a
small amount of powder may also be released:
R The bang will not generally af fect your hear‐
