Introduction
G WARNING Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal. The operating and road safety of the vehicle is jeopardised. There is a risk of an accident. Make sure that all objects in the vehicle are stowed correctly, and that they cannot enter the driver's footwell. Fit the floormats securely and as specified in order to ensure sufficient clearance for the pedals. Do not use loose floormats.
! If the engine is switched off and equip-
ment on the diagnostics connection is used, the starter battery may discharge. Connecting equipment to the diagnostics connection can lead to emissions monitoring information being reset, for example. This may lead to the vehicle failing to meet the requirements of the next emissions test dur- ing the main inspection.
Qualified specialist workshop A qualified specialist workshop has the nec- essary special skills, tools and qualifications to correctly carry out any necessary work on your vehicle. This particularly applies to work relevant to safety. Observe the notes in the Service Booklet. Always have the following work carried out at a qualified specialist workshop: Rwork relevant to safety Rservice and maintenance work Rrepair work Rmodifications, installations and conver-
sions
Rwork on electronic components Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre.
Vehicle registration Mercedes-Benz may ask its Service Centres to carry out technical inspections on certain vehicles. The quality or safety of the vehicle is improved as a result of the inspection. Mercedes-Benz can only inform you about vehicle checks if it has your registration data. It is possible that your vehicle has not yet been registered in your name in the following cases: Rif your vehicle was not purchased at an
authorised specialist dealer.
Rif your vehicle has not yet been examined
at a Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a Mercedes-Benz Service Centre. Inform Mercedes-Benz as soon as possible about any change in address or vehicle own- ership.
Correct use If you remove any warning stickers, you or others could fail to recognise certain dangers. Leave warning stickers in position. Observe the following information when driv- ing your vehicle: Rthe safety notes in this manual Rthe technical data in this manual Rtraffic rules and regulations Rlaws and safety standards pertaining to
motor vehicles

about the proper operation of your vehicle as well as about possible vehicle damage. Damage to your vehicle that arises from culpable contraventions against these instructions are not covered either by Mercedes-Benz implied warranty or by the New or Used-Vehicle Warranty.
Data stored in the vehicle
A number of electronic components in your vehicle contain data memories. These data memories temporarily or perma- nently store technical information about: Rthe vehicle's operating state Revents Rfaults This technical information generally docu- ments the condition of a component, a mod- ule, a system or an environment. These are, for example: Roperating conditions of system compo-
nents. This includes, e.g. fluid levels.
Rstatus messages from the vehicle and from
individual vehicle components. This includes, e.g. number of wheel revolu- tions/speed, deceleration, lateral acceler- ation.
Rmalfunctions and faults in important sys- tem components. This includes, e.g. lights, brakes.
Rreactions of the vehicle in special driving situations. This includes, e.g. deployment of an airbag, intervention of stability control systems.
Renvironmental conditions. This includes,
e.g. the outside temperature.
This data is exclusively technical in nature and is used to: Rassist in the detection and rectification of
faults and defects
Roptimise vehicle functions The data cannot be used to trace the vehicle's movements over distances travelled. When your vehicle is serviced, this technical information can be read out from the event and fault memory. Services include: Rrepairs Rservice processes

Useful information
i This Owner's Manual describes all mod- els, series and optional equipment for your vehicle that were available at the time of going to press. National variations are pos- sible. Note that your vehicle may not be equipped with all of the functions descri- bed. This is also the case for systems and functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24).
Occupant safety Important safety notes G WARNING If service work is not carried out correctly, the operating safety of your vehicle may be affec- ted. This could cause you to lose control of your vehicle and cause an accident. More- over, the safety systems may no longer be able to protect you or others as they are designed to do. Always have service work carried out at a qualified specialist workshop. G WARNING Modifications to or work performed incor- rectly on the following parts can result in the restraint systems not functioning as intended: Rthe restraint system, consisting of seat
belts and their anchorage points, belt ten- sioners, belt force limiters and airbags
Rthe wiring Rnetworked electronic systems Airbags and belt tensioners could fail to deploy or be triggered in an accident despite the deceleration force being sufficient to trig- ger the systems, or could be triggered unin- tentionally. For this reason, never make any modifications to the restraint systems. Therefore, you must not tamper with elec- tronic components or their software.
The seat belts, together with SRS (Supple- mental Restraint System), are complemen- tary, co-ordinated restraint systems (Y page 41). They reduce the risk of injury in specific, pre-defined types of accident sit- uations and thereby increase occupant safety. However, seat belts and airbags gen- erally do not protect against objects pene- trating the vehicle from the outside. To ensure that the restraint systems can deliver their full potential protection, make sure that: Rthe seat and head restraint are adjusted
properly (Y page 92)
Rthe seat belt has been fastened properly
(Y page 46)
Rthe airbags can inflate unrestricted if
deployed (Y page 42)
Rthe steering wheel is adjusted properly
(Y page 98)

Rthe restraint systems have not been modi-
An airbag increases the protection of vehicle occupants wearing a seat belt. However, air- bags are only an additional restraint system which complements, but does not replace, the seat belt. All vehicle occupants must wear their seat belt 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 prevents the vehicle occupant from being propelled towards the point of impact.
SRS (Supplemental Restraint System) Introduction Supplemental Restraint System (SRS) with: RThe 6 SRS warning lamp RAirbags RAirbag control unit (with crash sensors) RBelt tensioners for the front seat belts and
the outer seat belts in the rear
RSeat belt force limiters for the front seat belts and the outer seat belts in the rear SRS reduces the risk of occupants coming into contact with parts of the vehicle's interior in the event of an accident. It can also reduce the forces to which occupants are subjected during an accident.
SRS warning lamp G WARNING If SRS is malfunctioning, individual systems may be triggered unintentionally or might not be triggered in the event of an accident with a high rate of vehicle deceleration. A malfunction has occurred if: Rthe 6 SRS warning lamp does not light
up when the ignition is switched on.
Rthe engine is running and the 6 SRS warning lamp does not go out after a few seconds.
Rthe engine is running and the 6 SRS
warning lamp lights up again.
In this case, have SRS checked immediately at a qualified specialist workshop.
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. SRS functions are checked regularly when the ignition is switched on or the engine is run- ning. Therefore, malfunctions can be detec- ted in good time.
Occupant safety

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: Rduration Rdirection Rmagnitude Based on the evaluation of this data, the air- bag control unit pre-emptively 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 detected rate of deceleration or acceleration of the vehicle. This process is pre-emptive in nature. The triggering process must take place in good time at the start of the collision. The rate of vehicle deceleration or accelera- tion and the direction of the force are essen- tially determined by: Rthe distribution of forces during the colli-
sion
Rthe collision angle Rthe deformation characteristics of the vehi-
cle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured after a collision has occurred do not play a decisive role in the deployment of an airbag,
42 Occupant safety
nor do they provide an indication of airbag deployment. The vehicle may be deformed significantly, e.g. the bonnet or the wing, without an airbag being deployed. This is the case if only parts which are relatively easily deformed are affec- ted and the rate of deceleration is not high. Conversely, airbags may be deployed even though the vehicle suffers only minor defor- mation. This is the case if, for example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs as a result. i The front belt tensioners can only be trig- gered if the seat belt tongues on the front seats are correctly engaged in the seat belt buckles.
i Not all airbags are deployed in an acci- dent. The different airbag systems work independently of each other. How the airbag system works is deter- mined by predicting the severity of the acci- dent, especially vehicle deceleration or acceleration, and the type of accident: Rhead-on collision Rside impact Roverturn
Airbags Important safety notes G WARNING Airbags provide additional protection; they are not, however, a substitute for seat belts. Observe the following notes to reduce the risk of serious or even fatal injury caused by airbag deployment: Rall vehicle occupants – in particular, preg-
nant women – must wear their seat belt correctly at all times and lean back against the backrest, which should be positioned as close to the vertical as possible. The
head restraint must support the back of the head at about eye level.
Ralways secure children less than
1.50 m tall or under 12 years of age in suit- able child restraint systems.
Rall vehicle occupants must select a seat
position that is as far away from the airbag as possible. The driver's seat position must allow the vehicle to be driven safely. The driver's chest should be as far away from the centre of the driver's airbag cover as possible.
Rmove the front-passenger seat as far back as possible. This is especially important if you have secured a child in a child restraint system on the front-passenger seat.
Rvehicle occupants – in particular, children – must not lean their head into the area of the window in which the sidebag/window- bag is deployed.
Rrearward-facing child restraint systems
must not be fitted to the front-passenger seat unless the front-passenger airbag has been disabled. On the front-passenger seat, the front-passenger airbag is disabled if a child restraint system with a trans- ponder for automatic child seat recognition is fitted to the front-passenger seat in a vehicle equipped with automatic child seat recognition. The 4 PASSENGER AIRBAG OFF indicator lamp must be continuously lit. If the front-passenger seat of your vehicle does not have automatic child seat recog- nition, or your rearward-facing child restraint system does not have a trans- ponder for automatic child seat recogni- tion, children must be secured in a child restraint system on a suitable seat in the rear. If you secure a forward-facing child restraint system to the front-passenger seat, you must move the front-passenger seat as far back as possible.
Rmake sure there are no heavy or sharp- edged objects in the pockets of clothing.
Rdo not lean forwards, e.g. over the cover of the driver's/front-passenger front airbag, particularly when the vehicle is in motion.
Rdo not put your feet on the dashboard. Ronly hold the steering wheel on the outside. This allows the airbag to be fully deployed. You could be injured if the airbag is deployed and you are holding the inside of the steering wheel.
Rdo not lean on the doors from inside the
vehicle.
Rmake sure that there are no people, ani-
mals or objects between the vehicle occu- pants and the area where the airbags are deployed.
Rdo not place any objects between the seat
backrest and the door.
Rdo not hang any hard objects, e.g. coat
hangers, on the grab handles or coat hooks. Rdo not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury being caused by an airbag, due to the high speed at which the airbag must be deployed. G WARNING Airbag functionality can only be assured if the following parts are not covered and no badges or stickers are attached to them: Rpadded steering wheel boss Rkneebag cover below the steering column Rfront-passenger airbag cover Router side of front seat bolsters Rside trim next to the rear seat backrest Rroof frame cover between the front A-pillar
and the C-pillar in the rear compartment G WARNING When an airbag deploys, a small amount of powder is released. The powder may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions.
Occupant safety
43
In order to prevent potential breathing diffi- culties, 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 enter the vehicle interior. The powder does not constitute a health hazard and does not indicate that there is a fire in the vehicle. G WARNING The airbag parts are hot after the airbag has been deployed. Do not touch them as you could burn yourself. Have the airbags replaced at a qualified spe- cialist workshop. Otherwise, occupants are not protected by the airbags in the event of another accident.
Airbag deployment slows down and restricts the movement of the vehicle occupant. 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. The 6 SRS warning lamp lights up. The airbag installation locations are identified by the AIRBAG symbol.
Front airbags ! Do not place heavy objects on the front-
passenger seat. The system may then detect that the seat is occupied and if there is an accident, the restraint systems on the front-passenger side could be deployed. Have restraint systems that have been trig- gered replaced.
44 Occupant safety
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: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction
Rif the system determines that airbag
deployment can offer additional protection to that provided by the seat belt

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 airbag ; is only activated if the system determines that the front-passenger seat is occupied. The 4 PASSENGER AIR- BAG OFF indicator lamp on the centre con- sole does not light up (Y page 52).
If a child restraint system is fitted to the front- passenger seat and the PASSENGER AIRBAG OFF 4 indicator lamp on the centre con- sole is not on: Ra child restraint system without a trans-
ponder for automatic child seat recognition has been fitted or
Ra child restraint system with a transponder
has been fitted incorrectly
Driver's kneebag
Driver's kneebag : deploys under the steer- ing column. The driver's kneebag is triggered together with the front airbag. The driver's kneebag is designed to operate together with the front airbag in frontal impacts if certain thresholds are exceeded. The driver's knee- bag operates best in conjunction with cor- rectly positioned and fastened seat belts. Driver's kneebag : increases the driver's protection against: Rknee injuries Rthigh injuries Rlower leg injuries
Sidebags G WARNING If you wish to use seat covers, Mercedes-Benz recommends that, for safety reasons, you only use seat covers that have been approved for Mercedes-Benz vehicles. The seat covers must have a special tear seam for sidebags. Otherwise, the sidebags cannot
deploy correctly and would fail to provide the intended protection in the event of an acci- dent. Appropriate seat covers can be obtained, for example, from a Mercedes-Benz Service Centre.
Windowbags
Occupant safety
45
Front sidebags : and rear sidebags ; deploy next to the outer seat cushions. When deployed, the sidebags offer additional protection of the thorax for occupants on the front seats as well as also of the pelvis for the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the: Rhead Rneck Rarms The sidebags are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or accelera- tion, e.g. in a side impact
Rindependently of the use of the seat belt Rindependently of the front airbags Rindependently of the belt tensioners If the vehicle overturns, the sidebags are gen- erally not deployed. Sidebags are deployed if the system detects high vehicle deceleration or acceleration in a lateral direction and determines that sidebag deployment can offer additional protection to that provided by the seat belt.
Windowbags : enhance the level of protec- tion for the head (but not chest or arms), of the vehicle occupants on the side of the vehi- cle on which the impact occurs. Windowbags : are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. Windowbags are deployed: Rat the start of an accident with a high rate of lateral vehicle deceleration or accelera- tion, e.g. in a side impact
Ron the side on which an impact occurs Ron the driver's and the front passenger's
side if the vehicle overturns and the system determines that deployment can offer addi- tional protection to that provided by the seat belt
Rindependently of the use of the seat belt Rregardless of whether the front-passenger

PRE-SAFE® (anticipatory occupant protection) G WARNING When adjusting the seat, make sure that nobody can become trapped.
! Make sure that there are no objects in the footwell or behind the seats when moving the seat back. There is a risk that the seats and/or the objects could be damaged.
46 Occupant safety
PRE-SAFE® takes pre-emptive measures to protect occupants in certain hazardous sit- uations. PRE-SAFE® intervenes: Rwhen BAS activates, e.g. in emergency
braking situations
Rwhen adaptive Brake Assist intervenes powerfully on vehicles with DISTRONIC PLUS
Rin critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle understeers or oversteers severely
PRE-SAFE® takes the following measures depending on the hazardous situation detec- ted: Rthe front seat belts are pre-tensioned. Rvehicles with the memory function: the
front-passenger seat is adjusted if it is in an unfavourable position.
Rif the vehicle skids, the panorama sliding sunroof and the side windows are closed so that only a small gap remains.
If the hazardous situation passes without resulting in an accident, PRE-SAFE® slackens the belt pretensioning. All settings made by PRE-SAFE® can then be reversed. If the seat belts are not released: X Move the backrest or seat back slightly, but
only when the vehicle is stationary. The belt pretensioning is reduced and the locking mechanism is released.
More information about seat belt adjustment, a convenience function integrated into PRE- SAFE (Y page 47).
Seat belts Important safety notes G WARNING A seat belt which is not worn correctly, or which has not been engaged in the seat belt buckle correctly, cannot provide the intended level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju- ries in the event of an accident. Therefore, make sure that all occupants — in particular, pregnant women — wear their seat belts correctly at all times. RThe seat belt must fit snugly on your body and must not be twisted.Therefore, avoid wearing bulky clothing, e.g. a winter coat. The shoulder section of the belt must be routed across the centre of your shoulder — on no account across your neck or under your arm — and pulled tight against your upper body. The lap belt must always pass across your lap as low down as possible, i.e. over your hip joints — not across your abdo- men. If necessary, push the seat belt slightly downwards and adjust it by pulling it in the direction the seat belt retracts.
RDo not route the seat belt strap over sharp
or fragile objects. Please make sure that such objects are not on or in your clothing, e.g. spectacles, pens or keys etc. The seat belt strap could become damaged and tear during an accident and you or other vehicle occupants could be injured.
ROnly one person should use each seat belt at any one time. Children must never travel sitting on the lap of another occupant. The child will not be secured in the event of an accident, heavy braking or sudden change of direction. This may result in the child or other occupants being seriously or fatally injured.
RPersons under 1.50 m tall cannot wear the seat belts correctly. For this reason secure persons less than 1.50 m tall in specially designed, suitable restraint systems.
RChildren under 1.50 m tall and younger
than twelve years of age cannot wear the seat belts correctly. For this reason secure them in special suitable child restraint sys- tems installed on a suitable seat. Additional information can be found in the Operating Instructions in the chapter "Safety", "Chil- dren in the Vehicle". Observe the installa-
tion instructions of the child restraint sys- tem manufacturer.
RDo not secure an object with a seat belt if the seat belt is also being used by one of the vehicle's occupants. G WARNING The seat belt does not offer the intended level of protection unless the backrest is almost vertical. Under certain circumstances, this could cause severe or even fatal injuries in the event of an accident. Before starting a journey, make sure that the seat is properly adjusted and that the back- rest is almost vertical. G WARNING A dirty or damaged seat belt or one that has been modified or subjected to a load in an accident no longer offers the intended level of protection. Under certain circumstances, this could cause severe or even fatal injuries in the event of an accident. For this reason, check regularly that the seat belts are not damaged or dirty. Always have damaged seat belts or seat belts that have been subjected to a load in an acci- dent replaced at a qualified specialist work- shop. For safety reasons, Mercedes-Benz recom- mends that you only use seat belts which have been approved by Mercedes-Benz for your vehicle.
Seat belts are the most effective means of restraining the movement of vehicle occu- pants in the event of an accident. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior.

X If necessary, adjust the seat belt to the
appropriate height (Y page 48).
X If necessary, pull upwards on the shoulder section of the seat belt to tighten the belt across your body.
Information on releasing the seat belt with release button ?(Y page 48).
Seat belt adjustment The seat-belt adjustment function adjusts the driver's and front-passenger seat belt to the upper body of the occupants.
48 Occupant safety
The belt strap is tightened slightly when: Ryou engage the belt tongue in the belt
buckle and you then turn the key to position 2 in the ignition lock.
Rthe key is in position 2 in 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 seat-belt adjustment on and off in the on-board com- puter (Y page 225). The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. More information about PRE-SAFE® can be found in the "PRE-SAFE® (preventative occupant protection)" section (Y page 45).
Belt height adjustment
You can adjust the belt height for the front seats. Adjust the belt to a height that allows the upper part of the seat belt to be routed across the centre of your shoulder. X To raise: slide the belt sash guide upwards. The belt sash guide engages in various posi- tions.
X To lower: press and hold belt sash guide
release :.
X Slide the belt sash guide downwards. X Let go of belt sash guide release : and make sure that the belt sash guide has engaged.
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. Visit a qualified specialist workshop.

Belt warning for the driver and front passenger The 7 seat belt warning lamp in the instru- ment cluster is a reminder for all occupants to fasten their seat belts. It may light up con- tinuously or flash. In addition, a warning tone may sound. The 7 seat belt warning lamp goes out and the warning tone ceases when the driver and the front passenger have fastened their seat belt. For certain countries only: regardless of whether the driver and the front passenger have fastened their seat belts, the 7 seat belt warning lamp lights up for six seconds after the engine is started. It then goes out if

in the event of another accident. Therefore, have belt tensioners which have been trig- gered replaced at a qualified specialist work- shop. Comply with safety regulations when dispos- ing of belt tensioners. Any Mercedes-Benz Service Centre can provide details of these regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in the buckle on the front-passenger seat. Otherwise, the belt tensioner could be trig- gered in the event of an accident.
Example: rear seat belt status indicator The rear-compartment seat belt status indi- cator indicates the rear seat on which the belt is fastened. In the example, the occupant on the right rear seat, when viewed in the direc- tion of travel, is secured. The ü symbol in the display indicates a fastened seat belt. If a seat belt is not fastened or if a seat is not occupied, the ý symbol is displayed. The rear-compartment seat belt status indi- cator appears in the multifunction display for around 30 seconds if: Ryou drive off and reach a speed of approx-
imately 10 km/h.
Rthe rear passengers fasten or unfasten
their seat belts while the vehicle is in motion.
Rsomeone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status indicator immediately (Y page 229). i The status indicator for the rear-compart- ment seat belts is only available for certain countries.
Belt tensioners, belt force limiters G WARNING If the seat belt tensioners have been trig- gered, they provide no additional protection
The front seat belts and the outer seat belts in the rear are equipped with belt tensioners and belt force limiters. 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: Rthe ignition is switched on. Rthe restraint systems are operational; see
"6 SRS warning lamp" (Y page 41).
Rthe belt tongue is engaged in the buckle on
each of the front seat belts.
The belt tensioners on the outside seats in the rear compartment are triggered independ- ently of the lock status of the seat belts. The belt tensioners are triggered depending on the type and severity of an accident: Rif, in the event of a head-on or rear-end col-
lision the vehicle decelerates or acceler- ates rapidly in a longitudinal direction dur- ing the initial stages of the impact
Rif, in the event of a side impact, on the side
opposite the impact the vehicle deceler-
50

ates or accelerates rapidly in a lateral direc- tion
Rin certain situations where the vehicle over- turns and the system determines that it can provide 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. The 6 SRS warning lamp lights up. If the seat belt is also fitted with a belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced. The belt force limiters on the front seats are synchronised with the front airbags, which take on a part of the deceleration force. This results in the load being distributed over a greater area.
Children in the vehicle Child restraint systems Important safety notes G WARNING To reduce the risk of serious or even fatal injury to the child in the event of a sudden change in direction, braking or an accident: Rchildren less than 1.50 m tall and under
twelve years of age must always be secured in special child restraint systems on a suit- able vehicle seat. This is necessary because the seat belts are not designed for children.
RDo not drive with a child secured in a rear- ward-facing child restraint system on the front-passenger seat. Exception: if the vehi- cle is equipped with automatic child seat recognition on the front-passenger seat and the child is secured in a child restraint system with transponders for automatic child seat recognition
Rif you secure a forward-facing child
restraint system to the front-passenger seat, you must move the front-passenger seat as far back as possible.
Rchildren must never travel sitting on the lap
of another occupant. Due to the forces which occur in the event of a sudden change of direction, heavy braking or an accident, it would not be possible to restrain the child. The child could be thrown against parts of the vehicle interior and be seriously or even fatally injured. G WARNING The child restraint system cannot perform its protective function if it is not correctly fitted to a suitable vehicle seat. The child cannot be restrained in the event of an accident, heavy braking or sudden changes of direction. The child could be seriously or even fatally injured. For this reason, when fitting a child restraint system, observe the manufacturer's installa- tion instructions and the correct use of the child restraint system. Child restraint systems should be fitted to the rear seats. Children are generally better pro- tected there. The entire base of the child restraint system must always rest on the seat cushion. There- fore, never place objects, e.g. a cushion, under the child restraint system. Only use child restraint systems with the orig- inal cover designed for them. Only replace damaged covers with genuine Mercedes-Benz covers. We recommend the use of child restraint sys- tems which have been approved for Mercedes-Benz vehicles. G WARNING Do not leave children unsupervised in the vehicle, even if they are secured in a child restraint system. They could injure them- selves on parts of the vehicle. They could also be seriously or even fatally injured by pro- longed exposure to extreme heat or cold.

Do not expose the child restraint system to direct sunlight. Parts of the child restraint sys- tem could heat up and the child could burn herself/himself on them. If a child opens a door, the child or other per- sons could be injured as a result. They could get out and injure themselves or be injured by a passing vehicle. Observe the general notes on the HOLD func- tion, which can be found under the same key- word. G WARNING Unsecured or incorrectly positioned loads increase the risk of injury for children and all other occupants in the event of: Ran accident Rsudden braking Ra sudden change of direction Do not transport heavy or hard objects in the vehicle interior unless they are secured. You will find further information under "Loading guidelines" in the index.
If a child is travelling in your vehicle, secure the child using a child restraint system which is appropriate to the size, age and weight of the child. You should preferably fit the restraint system to a suitable rear seat. Make sure that the child is secured for the trip. Mercedes-Benz recommends that you use the listed child restraint systems (Y page 58). You can obtain further infor- mation about the correct child restraint sys- tem from any Mercedes-Benz Service Centre. i It is advisable to use Mercedes-Benz care products to clean child restraint systems. You can obtain information about this at any Mercedes-Benz Service Centre.
Child restraint system on the front- passenger seat G WARNING If the front-passenger airbag is not disabled: Ra child secured in a child restraint system on the front-passenger seat could be seri- ously and even fatally injured by the front- passenger airbag deploying. This is espe- cially a risk if the child is in the immediate vicinity of the front-passenger airbag when it deploys.
Rnever secure a child on the front-passenger seat in a rearward-facing child restraint sys- tem. Only secure a rearward-facing child restraint system on a suitable rear seat. Ralways move the front-passenger seat to the rearmost position if you secure a child in a forward-facing child restraint system on the front-passenger seat.
The front-passenger airbag is not disabled: Ron vehicles without automatic child seat recognition on the front-passenger seat Rin vehicles with automatic child seat rec- ognition in the front-passenger seat, if no special child restraint system with trans- ponders for automatic child seat recogni- tion in the front-passenger seat has been fitted
Ron vehicles with automatic child seat rec- ognition on the front-passenger seat, if the PASSENGER AIRBAG OFF indicator lamp 4 is not lit.
To make you aware of this danger, a corre- sponding warning sticker has been affixed on the dashboard and on both sides of the sun visor on the front-passenger side. Information about recommended child restraint systems is available at any Mercedes-Benz Service Centre.

Automatic child seat recognition on the front-passenger seat G WARNING If the 4 PASSENGER AIRBAG OFF indica- tor lamp does not light up when the child restraint system is fitted, the front-passenger airbag has not been disabled. If the front- passenger airbag deploys, the child could be seriously or even fatally injured. Proceed as follows: Rdo not use a rearward-facing child restraint
system on the front-passenger seat.
Rfit a rearward-facing child restraint system
on a suitable rear seat.
or
Ronly use a forward-facing child restraint system on the front-passenger seat and move the front-passenger seat to the rear- most position.
Rhave the automatic child seat recognition checked at a qualified specialist workshop. To ensure that the automatic child seat rec- ognition on the front-passenger seat func- tions/communicates correctly, never place objects, e.g. a cushion, under the child restraint system. The entire base of the child restraint system must always rest on the seat cushion. An incorrectly fitted child restraint system cannot perform its intended protec- tive function in the event of an accident, and could lead to injuries. G WARNING Do not place electronic devices on the front- passenger seat, e.g.: Rlaptops, when switched on Rmobile phones Rcards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause interference in the automatic child seat rec- ognition sensor system. This can lead to a system malfunction. This may cause the 4 PASSENGER AIRBAG OFF indicator lamp to light up without there being a child seat with transponders for automatic child seat recognition fitted. The front-passenger airbag will not then deploy during an accident. It is also possible that the 6 SRS warning lamp lights up and/or the 4 PASSENGER AIRBAG OFF indicator lamp does not light up briefly when you turn the key in the ignition lock to position 2.
