Protection of the environment General notes H Environmental note Daimler's declared policy is one of compre- hensive environmental protection. Our objectives are to use the natural resour- ces which form the basis of our existence on this planet sparingly and in a manner which takes the requirements of both nature and humanity into consideration. You too can help to protect the environment by operating your vehicle in an environmen- tally-responsible manner. Fuel consumption and the rate of engine, transmission, brake and tyre wear depend on the following factors: Roperating conditions of your vehicle Ryour personal driving style You can influence both factors. Therefore, please bear the following in mind: Operating conditions: Ravoid short trips, as these increase fuel
consumption.
Robserve the correct tyre pressure. Rdo not carry any unnecessary weight in the
vehicle.
Rremove the roof rack once you no longer
need it.
Ra regularly serviced vehicle will contribute
to environmental protection. You should therefore adhere to the service intervals.
Rall maintenance work should be carried out
at a qualified specialist workshop.
Personal driving style: Rdo not depress the accelerator pedal when
starting the engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. Rswitch off the engine in stationary traffic. Rmonitor the vehicle's fuel consumption.
Returning an end-of-life vehicle EU countries only: Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-respon- sible manner in accordance with the Euro- pean Union (EU) End of Life Vehicles Direc- tive. There is a network of return points and dis- assembly plants available. You can return your vehicle to these plants free of charge. This makes a valuable contribution to the recycling process and the conservation of resources. For further information on recycling old vehi- cles, recovery and the terms of the policy, visit the Mercedes-Benz homepage.
Genuine Mercedes-Benz parts
H Environmental note Daimler AG also supplies reconditioned assemblies and parts which are of the same quality as new parts. For these, the same war- ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars Rdoor sills Rseats Rdashboard Rinstrument cluster Rcentre console
26
Introduction
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: Rif they cause a change of the vehicle type from that for which the vehicle's general operating permit was granted
Rif other road users could be endangered Rif the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) (Y page 382) when ordering genu- ine Mercedes-Benz parts.
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 Mercedes-Benz Service Centre. The Owner's Manual and Service Booklet are important documents and should kept in the vehicle.
Operating safety Important safety notes G 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.
Introduction

G WARNING Modifications to electronic components, their software as well as wiring could effect their function and/or the operation of other net- worked components. This could in particular also be the case for systems relevant to safety. They might not function properly any more and/or jeopardise the operational safety of the vehicle. There is an increased risk of an accident and injury. Do not attempt to modify the wiring as well as electronic components or their software. Always have work on electrical and electronic components carried out at a qualified special- ist workshop.
! There is a risk of damage to the vehicle if:
Rthe vehicle makes contact with the
ground, e.g. on a high kerb or a loose road surface
Ryou drive too quickly over an obstacle,
e.g. a kerb or a pothole
Ra heavy object hits the underbody or
chassis component
In these or similar situations, the vehicle body, the underbody, chassis components, wheels or tyres could be damaged even if this is not visible. Components that have been damaged in this way can unexpect- edly fail or no longer be able to assimilate the loads occurring in the event of an acci- dent. If the underbody panelling is damaged, flammable material, such as leaves, grass or twigs, could collect between the under- body and underbody panelling. These materials could ignite if they remain in con- tact with hot components of the exhaust system for an extended period. Have the vehicle checked and repaired immediately at a qualified specialist work- shop. If you become aware when continu- ing the journey that driving safety has been effected, stop as soon as possible in accordance with the traffic conditions. In
such cases, consult a qualified specialist workshop.
Declarations of conformity Wireless vehicle components The following information applies to all com- ponents of the vehicle and the information systems and communication devices integra- ted into the vehicle which receive and/or transmit radio waves: The components of this vehicle that receive and/or transmit radio waves are compliant with the basic requirements and all other rel- evant conditions of Directive 1999/5/EC. You can obtain further information from any Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi- cle components has been checked and certi- fied according to the currently valid version of Regulation ECE-R 10.
Diagnostics connection The diagnostics connection is only intended for the connection of diagnostic equipment at a qualified specialist workshop. G WARNING If you connect equipment to a diagnostics connection in the vehicle, it can affect the operation of the vehicle systems. This may affect the operating safety of the vehicle. There is a risk of an accident. Do not connect any equipment to a diagnos- tics connection in the vehicle. G WARNING Objects in the driver's footwell may restrict the clearance around the pedals or block a depressed pedal. This jeopardises the oper- ating and road safety of the vehicle. There is a risk of an accident.
28
Introduction
Stow all objects securely in the vehicle so that they do not get into the driver's footwell. Always fit the floormats securely and as pre- scribed in order to ensure that there is always sufficient room for the pedals. Do not use loose floormats and do not place several floor- mats on top of one another.
! 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. You can do this at a Mercedes-Benz Service Centre, for example.
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
Implied warranty ! Follow the instructions in this manual
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 wide range 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 In general, this technical information docu- ments the state of a component, a module, a system or the surroundings. These include, for example: Roperating conditions of system compo-
nents, e.g. fluid levels
Rthe vehicle's status messages and those of its individual components, e.g. number of wheel revolutions/speed, deceleration in movement, lateral acceleration, accelera- tor pedal position
Rmalfunctions and defects in important sys-
tem components, e.g. lights, brakes
Rvehicle reactions and operating conditions
in special driving situations, e.g. airbag deployment, intervention of stability con- trol systems
Rambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature and can be used to: Rassist in recognising and rectifying faults
and defects
Ranalyse vehicle functions, e.g. after an acci-
dent
Roptimise 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 mem- ory and fault data memory. Services include, for example: Rrepair services Rservice processes Rwarranties Rquality assurance It is read by employees of the service network (including manufacturers) using special diag-

nostic testers. More detailed information is obtained from it, if required. After a fault has been rectified, the informa- tion is deleted from the fault memory or is continually overwritten. When operating the vehicle, situations are conceivable in which this technical data, in connection with other information (if neces- sary, under consultation with an authorised expert), could be traced to a person. Examples include: Raccident reports Rdamage to the vehicle Rwitness statements Further additional functions that have been contractually agreed upon with the customer allow certain vehicle data to be conveyed by the vehicle as well. The additional functions include, for example, vehicle location in case of an emergency.

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 28).

Occupant safety Important safety notes G 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 example. 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 45). 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 102)
Rthe seat belt has been fastened properly
(Y page 54)
Rthe airbags can inflate unrestricted if
deployed (Y page 46)
Rthe steering wheel is adjusted properly
Rthe restraint systems have not been modi-
(Y page 102)
fied
i An airbag increases the protection of vehicle occupants wearing a seat belt. However, airbags are only an additional restraint system that complements, but does not replace, the seat belt. All vehicle
occupants must wear their seat belt cor- rectly at all times, even if the vehicle is equipped with airbags. The airbags are not deployed in all types of accidents. For example, if the protective capacity of cor- rectly fastened seat belts is not increased by deploying the airbags, the airbags will not deploy. Airbag deployment only pro- vides increased protection if the seat belt is worn correctly because: Rthe seat belt helps to keep the vehicle occupant in the best position in relation to the airbag.
Rin a head-on collision, for example, the seat belt prevents the vehicle occupant from being propelled towards the point of impact. It can thus reduce the risk of injury.
In accidents in which an airbag is deployed, it provides increased protection only if the seat belt is worn correctly.
SRS (Supplemental Restraint System) Introduction SRS consists of: Rthe 6 SRS warning lamp Rairbags Rairbag control unit (with crash sensors) Rbelt tensioners Rbelt force limiters SRS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the forces to which occupants are subjected dur- ing an accident.
SRS warning lamp G WARNING If SRS is malfunctioning, child restraint sys- tem components may be triggered uninten- tionally or might not be triggered at all in the event of an accident with a high rate of vehicle
Occupant safety

deceleration. 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 6 SRS warning lamp goes out while the engine is running. 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

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. 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.
If there is an even higher rate of vehicle decel- eration or acceleration in a longitudinal direc- tion, the front airbags are also deployed.
46 Occupant safety
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 exceeded within a few milliseconds. The belt tensioner and airbag triggering thresholds are variable and are adapted to the 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. i Airbags are not deployed in all types of
accidents. Also, not all airbags are deployed together in an accident. The dif- ferent airbag systems work independently of each other. How the airbag system works is deter- mined by the severity of the collision detec- ted, especially the vehicle deceleration or acceleration, and the apparent type of acci- dent: Rhead-on collision Rside impact Roverturn
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, 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.
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.
Occupant safety

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.
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. G WARNING If you modify the airbag covers or affix objects, e.g. stickers to them, the airbags may no longer function as intended. There is an increased risk of injury. Never modify the airbag covers and do not affix any objects to them. 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 After the driver's airbag has been deployed, the airbag parts are hot. There is a risk of injury.
Vehicles with automatic child seat recog- nition in the front-passenger seat: the front-passenger front airbag is only activated if the system determines that the front- passenger seat is occupied. The PASSENGER AIRBAG OFF indicator lamp on the centre console does not light up (Y page 59). If a child restraint system is fitted to the front- passenger seat and the PASSENGER AIRBAG OFF indicator lamp on the centre console 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
! 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 kneebag i The driver's kneebag is only available in
certain countries.
The driver's kneebag increases protection of the driver against: Rknee injuries Rthigh injuries Rlower leg injuries
48 Occupant safety
Do not touch the airbag parts. Have deployed airbags replaced immediately at a qualified specialist workshop.
The airbag installation locations are identified by the AIRBAG symbol. i After an airbag has been deployed, have the vehicle towed to the nearest qualified specialist workshop, even if your vehicle can still be driven.
Front airbags The front airbags increase protection for the driver's and front-passenger's head and chest.
Driver's airbag : deploys in front of the steering wheel; front-passenger front air- bag ; deploys in front of and above the glove compartment. They are deployed: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction.

cle.
The release time of the front airbags is dependant upon the use of the seat belt. If the vehicle overturns, the front airbags are generally not deployed. The front airbags are deployed if the system detects high vehicle deceleration in a longitudinal direction.
Driver's kneebag : is always deployed along with the driver's airbag and inflates under- neath the steering column.
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- elling carried out at a qualified specialist workshop.
You should only use seat cover that have been approved for your vehicle by Mercedes-Benz. The seat covers must have a special tear seam for sidebags. Otherwise, the sidebags cannot deploy correctly and therefore cannot provide the intended protection in the event of an accident.

only use seat covers that have been approved for Mercedes-Benz vehicles. The seat covers must have a special tear seam for sidebags/pelvisbags. Otherwise, the side- bag/pelvisbag cannot deploy correctly and would fail to provide the intended protection in the event of an accident. Appropriate seat covers can be obtained, for example, from a Mercedes-Benz Service Centre.
Pelvisbag deployment enhances the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs.
Pelvisbags : deploy next to and below the outer seat cushions. They 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

PRE-SAFE® intervenes: Rwhen BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
Rif, on vehicles with DISTRONIC PLUS, the radar sensor system detects an imminent danger of collision in certain situations
Rin critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle understeers or oversteers severely
If you are driving faster than approximately 30 km/h, PRE-SAFE® may take the following measures in these situations: 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. Seat belt pretensioning is reduced and the locking mechanism is released. 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.
More information about seat belt adjustment, a convenience function integrated into PRE- SAFE®, can be found in the "Seat belt adjust- ment" section (Y page 54).
NECK-PRO head restraints/NECK- PRO luxury head restraints G WARNING 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 fulfil their intended protective function in the event of an accident. In addition, objects attached to the head restraints could endanger other vehicle occupants. This poses an increased risk of injury. Do not attach any objects to the head restraints and do not use head restraint cov- ers.
NECK-PRO head restraints/NECK-PRO luxury head restraints increase protection of the driver's and front-passenger's head and neck. In the event of a rear collision of a cer- tain severity, the NECK-PRO head restraints/ NECK-PRO luxury head restraints on the driv- er's and front-passenger seats are moved for- wards and upwards. This provides better head support. If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats (Y page 52). Otherwise, the additional pro- tection will not be available in the event of another rear-end collision. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted. Mercedes-Benz recommends that you have the NECK-PRO head restraints/NECK-PRO luxury head restraints checked at a qualified specialist workshop after a rear-end collision.

Seat belts Important safety notes 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.
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-
