The QR code is secured in the fuel filler flap and
on the opposite side on the B-pillar. In the event
of an accident, rescue services can use the QR
code to quickly find the appropriate rescue card for your vehicle. The current rescue card con-
tains, in a compact form, the most important
information about your vehicle, e.g. the routing
of the electric cables.
You can find more information under http://
portal.aftersales.i.daimler.com/public/
content/asportal/en/communication/
informationen_fuer/QRCode.html. Data stored in the vehicle
A wide range of electronic components in your
vehicle contain data memories. These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system components,
e.g. fluid levels
R the vehicle's status messages and those of its
individual components, e.g. number of wheelrevolutions/speed, deceleration in move-
ment, lateral acceleration, accelerator pedal
position
R malfunctions and defects in important system
components, e.g. lights, brakes
R vehicle reactions and operating conditions in
special driving situations, e.g. airbag deploy-
ment, intervention of stability control sys-
tems
R ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using special diagnostic testers. You can obtain more
information there, if required.
After a fault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec- 28

Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This may affect
the seat belt tensioner or airbag, for example. This poses an increased risk of injury or even
fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG indicator lamp PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 46) and on "Children in the
vehicle" (Y page 54).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva-
tion system" (Y page 46) and on "Children in
the vehicle" (Y page 54).
R All other persons: the PASSENGER AIR BAG
ON indicator lamp must be lit. The front-
passenger front airbag is enabled. Depending on the build of the person on the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In
this case, the front-passenger seat should not be used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 46) as well as
on "Seat belts" (Y page 41) and "Airbags"
(Y page 43). There you can also find infor-
mation on the correct seat position. 40

Basic illustration
X Adjust the seat (Y page 101).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt smoothly out of seat belt
guide =and engage belt tongue ;into belt
buckle :.
The seat belt on the driver's seat and the
front-passenger seat may be tightened auto-
matically; see "Belt adjustment"
(Y page 43).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
Releasing the 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 fulfil their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press release button in belt buckle, hold belt
tongue firmly and guide the seat belt back.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This func-
tion 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 seat belt tongue is engaged in the belt
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
hold on to the seat belt tightly while it is adjust-
ing.
You can switch the seat-belt adjustment on and
off in the on-board computer (Y page 212).
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle occu-
pants must fasten their seat belts. It may light up continuously or flash. A warning tone may also
sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's
and the co-driver's seat belts have been fas-
tened. Airbags
Introduction The airbag installation location is identified by
the label AIRBAG.
An airbag supplements a correctly fastened seat
belt. It is not a substitute for seat belts. The air- bag provides additional protection in the corre-
sponding accident situations.
Not all airbags are deployed in an accident. The
various airbag systems work independently of
one another (Y page 51).
However, no system available today can com-
pletely eliminate injuries and fatalities.
Due to the required speed of the airbag after
deployment, it is also not possible to entirely
rule out the risk of injuries caused by the airbag.

are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears in the instrument clus-
ter (Y page 226). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the front-passenger front airbag both before
and during the journey.
If a person sits in the passenger seat, they must
be:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag does not then
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front- passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
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 rear- ward-facing child restraint system on the front-
passenger seat. Further information can be
found under "Problems with the automatic front-
passenger front airbag deactivation system"
(Y page 50). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit up.
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the Occupant safety

shoulder belt strap is correctly routed from
the vehicle seat belt guide to the shoulder belt
guide on the child restraint system. The shoul- der belt strap must be routed forwards and
downwards from the belt guide. Always
observe the child restraint system manufac-
turer's installation instructions.
If the automatic front-passenger front airbag
deactivation system detects that: R the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front airbag is disabled.
R the front-passenger seat is occupied by a
child in a rearward-facing child restraint sys-
tem, the PASSENGER AIR BAG OFF indicator
lamp lights up after the system self-test and
remains lit. This indicates that the front-
passenger front airbag is disabled.
But in the case of a child in a rearward-facing
child restraint, the PASSENGER AIR BAG ON
indicator lamp can light up after the system
self-test and remain lit. This indicates that the
front-passenger front airbag is enabled. The
result of the classification is dependent on,
among other factors, the child restraint sys-
tem and the child's build. Make sure that the
conditions for a correct classification are met. If the PASSENGER AIR BAG ON indicator lamp remains on, do not install a child restraint
system on the front-passenger seat.
R the front-passenger seat is occupied by a
child in a forward-facing child restraint sys-
tem, either the PASSENGER AIR BAG ON or
PASSENGER AIR BAG OFF indicator lamp
lights up and remains lit after the system self- test depending on the result of the classifica-
tion. The result of the classification is depend- ent on, among other factors, the child
restraint system and the child's build.
Move the front-passenger seat as far back as
possible. Always observe the information in
"Child restraint systems on the front-
passenger seat" (Y page 56) and in "Suita-
ble positioning of the child restraint system"
(Y page 58).
R the front-passenger seat is occupied by a per-
son with a smaller build (e.g. a teenager or
small adult), either the PASSENGER AIR BAG
ON or PASSENGER AIR BAG OFF indicator
lamp lights up and remains lit after the system self-test depending on the result of the clas-
sification.
- If the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger
seat as far back as possible.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person with a smaller build
should not use the front-passenger seat.
R the front-passenger seat is occupied by an
adult or a person with a build corresponding
to that of an adult, the PASSENGER AIR BAG
ON indicator lamp lights up after the system
self-test and remains lit. This indicates that
the front-passenger front airbag is enabled.
If children are travelling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
(Y page 54).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the red
6 restraint system warning lamp in the
instrument cluster and the PASSENGER AIR
BAG OFF indicator lamp light up simultaneously.
The front-passenger front airbag is disabled in
this case and does not deploy during an acci-
dent. Have the system checked as soon as pos-
sible by qualified technicians. Consult a
Mercedes-Benz Service Centre. The front-
passenger seat should only be repaired at a
Mercedes-Benz Service Centre.
If the front-passenger seat, the seat cover or the seat cushion is damaged, have the necessary
repair work carried out at a Mercedes-Benz Ser-vice Centre.
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint system
which has been tested and approved by
Mercedes-Benz in combination with the auto-
matic front-passenger front airbag deactivation
system.
System self-test G
DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front airbag might be triggered
unintentionally or might not be triggered at all in the event of an accident with high deceler-
ation. This poses an increased risk of injury or even fatal injury. 48

X Have the automatic front-passenger front airbag deactivation sys-
tem checked immediately at a qualified specialist workshop. Roll bars
G
DANGER
If the roll bar has developed a fault, it may not function, e.g. in the event of an accident. The
roll bars may then not protect the vehicle
occupants as intended. This poses an
increased risk of injury or even fatal injury.
Have roll bars checked immediately at a quali-
fied specialist workshop. G
WARNING
If you place objects or clothing on the roll bar covers, these could impair roll bar extension.
The roll bars may then not protect the vehicle occupants as intended. In addition, objects
could endanger the vehicle occupants when
the roll bar is extending. This poses an
increased risk of injury or even fatal injury.
Ensure that the movement area of the roll barcovers is kept clear. Always stow all objects in
the vehicle correctly. 50
Occupant safetySafety

The roll bars are located in the rear area of the
vehicle under the two outer rear compartment
trim covers.
They extend if systems detect that the vehicle is in danger of overturning. The two outer rear
compartment trim covers are opened and the
roll bars are extended within fractions of a sec-
ond.
Once the roll bars are extended, you can no lon-
ger lower them. An open roof can no longer be
closed. In this case, visit the nearest qualified
specialist workshop. Deployment of belt tensioners and air-
bags
Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnical belt tensioners which have
been triggered are no longer operational and
therefore cannot protect as intended. There is an increased risk of injury, possibly even fatal.
Have pyrotechnic belt tensioners which have
been triggered replaced at a qualified special-
ist workshop immediately.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. Take this into account, par- ticularly if a seat belt tensioner was triggered or
an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If the belt tensioners are triggered or an airbag is
deployed, you will hear a bang, and a small
amount of powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. In general, the powder released is not haz-
ardous to health but may cause short-term
breathing difficulties to persons suffering from
asthma or other pulmonary conditions. Provided it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre-vent breathing difficulties.
Operation During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the seat
belt tensioners in the event of a head-on or rear
collision.
A seat belt tensioner can only be triggered if:
R the ignition is switched on
R the components of the restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(Y page 40)
R the belt tongue has engaged in the belt buckle
of the respective seat
If the restraint system control unit detects a high severity accident, in certain head-on collisions,
additional components of the restraint system
are deployed independently of each other:
R front airbags
Depending on the person in the front-passenger seat, the front-passenger front airbag is either
disabled or enabled. The front-passenger front
airbag can only be deployed in an accident if the PASSENGER AIR BAG ON indicator lamp is lit.
Observe the information on the PASSENGER AIR
BAG indicator lamps (Y page 40). Occupant safety
