Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes. This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tyres, wheels and
accessories that have been specifically
approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or
independently approved by a testing centre.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes-
Benz parts (Y page 622). Owner's Manual
Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe- cific differences are possible. Note that your
vehicle may not be fitted with all features
described. This is also the case for systems
and functions relevant to safety. Therefore,
the equipment on your vehicle may differ from
that in the descriptions and illustrations.
The original purchase contract documenta-
tion for your vehicle contains a list of all of the
systems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a

WARNING
If you do not have the prescribed service/
maintenance work or necessary repairs car-
ried out, this could result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. 32

WARNING
Modifications to the restraint systems could
result in them not functioning properly any
more. The restraint systems could then no
longer protect vehicle occupants as they are
designed to do and could fail in the event of an accident or activate unexpectedly, for exam-
ple. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to modify the wiring as well as
electronic components or their software.
The airbag system can be adapted for a per-
son with disabilities. For further information,
consult a Mercedes-Benz Service Centre.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 51). They reduce the risk of injury in
specific, pre-defined types of accident situa-
tions and thereby increase occupant safety.
However, seat belts and airbags generally do
not protect against objects penetrating the
vehicle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 112)
R the seat belt has been fastened properly
(Y page 59)
R the airbags can inflate without restriction if
deployed (Y page 52)
R the steering wheel is adjusted properly
(Y page 118)
R the restraint systems have not been modi-
fied
An airbag increases the protection of vehicle
occupants wearing a seat belt. However, air-
bags are only an additional restraint system
that complements, but does not replace, the
seat belt. All vehicle occupants must wear 50
Occupant safetySafety

their seat belts correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents. For example, if the protective capacity of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
The seat belt helps, firstly, to keep the vehicle occupant in the best position in relation to the
airbag. Secondly, in a head-on collision, for
example, the seat belt restricts movement of
the vehicle occupant towards the point of
impact. SRS (Supplemental Restraint System)
Introduction SRS consists of:
R the 6 SRS warning lamp
R airbags
R the airbag control unit with crash sensors
R belt tensioners
R belt force limiters
SRS reduces the risk of vehicle occupants
coming into contact with parts of the vehi-
cle's interior in the event of an accident. It can
also reduce the forces to which vehicle occu- pants are subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with a high rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the engine is running. Therefore, malfunctions
can be detected in good time.
The
6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational read-
iness when the 6SRS warning lamp goes
out while the engine is running.
A malfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 6SRS
warning lamp lights up again
Triggering of belt tensioners and air-
bags During the first stage of a collision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit triggers the belt tensioners in the first stage.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc- tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air- bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. In the first deployment stage,
the front airbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deployment threshold is reached within a few
milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the Occupant safety
51Safety Z

specialist workshop, even if your vehicle
can still be driven.
Front airbags !
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 restraint
systems on the front-passenger side may
be triggered and have to be replaced. Driver's airbag
:deploys in front of the
steering wheel; front-passenger front air-
bag ;deploys in front of and above the glove
compartment.
The front airbags increase protection for the
driver's and front-passenger's head and
chest.
They are deployed:
R at the start of an accident with a high rate of
vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deployment can offer additional protection to that provided by the seat belt
R independently of other airbags in the vehi-
cle
The time within which the front airbag is
deployed is dependent on whether or not a
seat belt is worn.
If the vehicle overturns, the front airbags are
generally not deployed.
Vehicles with automatic child seat recog- nition in the front-passenger seat: front-
passenger front airbag ;is only enabled if the system determines that the front-
passenger seat is occupied.
Exception:if a
child restraint system with transponder is
installed correctly. The PASSENGER AIRBAG
ON indicator lamp lights up for 60 seconds
when the ignition is switched on. The
PASSENGER AIRBAG OFF indicator lamp on
the centre console does not light up
(Y page 63).
If a child restraint system is fitted to the front-
passenger seat and the PASSENGER AIRBAG
OFF indicator lamp is not on:
R a child restraint system without a trans-
ponder for automatic child seat recognition
has been fitted or
R a child restraint system with a transponder
has been fitted incorrectly
Sidebags G
WARNING
Unsuitable seat covers may obstruct or even
prevent deployment of the airbags integrated into the seats. The airbags may then fail to
protect the vehicle occupants as intended.
Operation of the automatic child seat recog-
nition may also be impaired. There is an
increased risk of injury, possibly even fatal.
Use only seat covers which have been specif-
ically approved for the respective seat by
Mercedes-Benz. G
WARNING
Sensors to control the airbags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ling, as well as damaged doors, can lead to the function of the sensors being impaired. The
airbags might therefore not function properly any more. Consequently, the airbags cannot
protect vehicle occupants as they are
designed to do. This poses an increased risk
of injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan- 54

Fastening seat belts X
Adjust the seat and move the backrest to
an almost vertical position (Y page 112).
X Pull the seat belt smoothly through seat
belt guide :.
X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of
your shoulder and the lap section across
your pelvis.
X Engage belt tongue ;in buckle =.
Seat belt adjustment: if necessary, the driv- er's and front-passenger seat belts auto-
matically adjust to the upper body
(Y page 59).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
Information about releasing the seat belt with
release button ?(Ypage 59).
Seat belt adjustment The seat-belt adjustment 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 you engage the belt tongue in the belt
buckle and you then turn the key to position
2 in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the belt adjustment
on and off using the on-board computer
(Y page 243).
The seat belt adjustment is a convenience
function integrated in PRE-SAFE ®
(preventa-
tive occupant protection). More information
on PRE-SAFE ®
(Y page 56).
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. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.

Belt warning for the driver and front
passenger The
ü seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants to
fasten their seat belts. It may light up contin- uously or flash. In addition, a warning tone
may sound.
The ü seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belt.
Only for certain countries: the üseat belt
warning lamp lights up for six seconds after
every engine start. This happens regardless of whether the driver's and front-passenger seatbelts have already been fastened. It then goes
out if the driver and the front passenger have fastened their seat belts.
i For more information on the
üseat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 274).
Belt tensioners, belt force limiters G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
! If the co-driver's seat is not occupied, do
not engage the seat belt tongue in the
buckle on the co-driver's seat. Otherwise,
the belt tensioner could be triggered in the
event of an accident and would have to be
replaced. i
Vehicles with PRE-SAFE ®
: an electric
motor is used by PRE-SAFE ®
to trigger the
tightening of the seat belt in hazardous sit-
uations. This procedure is reversible.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
The belt tensioners can only be activated
when:
R the ignition is switched on
R the restraint systems are operational; see "
SRS warning lamp" (Y page 51)
R the belt tongue is engaged in the buckle on
each of the three-point seat belts
The belt tensioners are triggered depending
on the accident type and severity:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite to the
impact
R in certain situations where the vehicle over-
turns and the system determines that it canprovide additional protection
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that thereis a fire in the vehicle. The powder may causeshort-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to 60
