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.

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

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 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 94)
Rthe seat belt has been fastened properly
(Y page 46)
Rthe airbags can inflate without restriction if
deployed (Y page 42)
Rthe steering wheel is adjusted properly
(Y page 100)

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 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 restricts movement of the vehicle occupant 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 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, 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 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
Rthe engine is running and the 6 SRS
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: 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.
42 Occupant safety
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. 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 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.
Occupant safety
43
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. Do not touch the airbag parts. Have deployed airbags replaced immediately at a qualified specialist workshop.
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 and does not indicate that there is a fire in the vehicle. The powder may cause short-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 enter the vehicle interior. The 6 SRS warn- ing lamp lights up. 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.
44 Occupant safety
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.
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

Driver's kneebag
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.
Rdepending on whether the seat belt is being

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 PASSENGER AIRBAG OFF indicator lamp on the centre console does not light up (Y page 53).
Driver's kneebag : deploys underneath the steering column. The driver's kneebag is trig- gered together with the front airbag. The driv- er's kneebag is designed to operate together with the front airbags in frontal impacts if cer- tain thresholds are exceeded. The driver's kneebag operates best in conjunction with correctly positioned and fastened seat belts. Driver's kneebag : increases the driver's protection against: Rknee injuries Rthigh injuries Rlower leg injuries
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.
Occupant safety

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.

Windowbags
Front sidebags : and rear sidebags ; deploy next to the outer seat cushions.
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.

PRE-SAFE® (anticipatory occupant protection) ! 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.
PRE-SAFE® takes pre-emptive measures to protect occupants in certain hazardous sit- uations. Although your vehicle is equipped with a PRE-SAFE® system, the possibility of injury in the event of an accident cannot be ruled out. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. 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. Seat belt pretensioning is reduced and the locking mechanism is released.
The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. More information about seat-belt adjustment can be found under "Seat-belt adjustment" (Y page 48).
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 if the backrest is not in the upright position. When braking or in the event of an accident, you could slide underneath the
Occupant safety
47
seat belt and sustain abdomen or neck inju- ries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always make sure that the seat is in the upright position. G WARNING Seat belts cannot perform their intended pro- tective function if: Rthey are damaged, modified, bleached or
coloured, or are very dirty
Rthe seat belt buckle is damaged or very
dirty
Rmodifications have been made to the seat
belt tensioners or belt anchorages
In the event of an accident, seat belts can sustain damage that is not visible to the naked eye, e. g. due to glass splinters. Modified or damaged seat belts could tear or fail in the event of an accident, for example. Modified belt tensioners could deploy unexpectedly or fail. There is an increased risk of serious or even fatal injuries. Never make modifications to seat belts, belt tensioners, belt anchorages or seat belt retractors. Make sure that the seat belts are undamaged, are not worn and are clean.
Mercedes-Benz recommends that you only use seat belts which have been approved specifically for your vehicle by Mercedes- Benz. 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.

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 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.
i Vehicles with PRE-SAFE®: belt tensioners that are triggered by an electric motor can be deployed as often as desired and do not need to be replaced.
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- 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 and does not indicate that there is a fire in the vehicle. The powder may cause short-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 enter the vehicle interior. The 6 SRS warn- ing 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 transport children who are secured in rearward-facing child restraint systems on the front-passenger seat. Exception: if the vehicle 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. When doing so, ensure that the shoulder belt strap from the belt outlet on the vehicle is routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjustment so that the belt strap is routed towards the front along the bottom. 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 If the child restraint system is incorrectly fit- ted on the seat position suitable for this pur- pose, it cannot perform its intended protec- tive function. In the event of an accident, sharp braking or a sudden change in direction, the child may not be held securely. There is an increased risk of serious or even fatal inju- ries. Observe the manufacturer's installation instructions and the correct use for the child restraint system. Make sure that the entire surface of the child restraint system is resting on the seat surface. Never place objects under or behind the child restraint system,

e.g. cushions. Only use child restraint sys- tems with the original cover designed for them. Only replace damaged covers with gen- uine covers. G WARNING If the child restraint system is fitted incor- rectly or is not secured, it can come loose in the event of an accident, heavy braking or a sudden change in direction. The child restraint system could be thrown about, strik- ing vehicle occupants. There is an increased risk of injury, possibly even fatal. Always fit child restraint systems properly, even if they are not being used. Make sure that you observe the child restraint system manufacturer's installation instructions. G WARNING Child restraint systems or their securing sys- tems that have been damaged or subjected to a load in an accident cannot perform their intended protective function. In the event of an accident, sharp braking or a sudden change in direction, the child may not be held securely. There is an increased risk of serious or even fatal injuries. Immediately replace child restraint systems that have been damaged or subjected to a load in an accident. Have the child restraint securing systems checked in a qualified spe- cialist workshop before fitting a child restraint system again. G WARNING If children are left unsupervised in the vehicle, they could: Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic. Roperate the vehicle's equipment.

Additionally, children could set the vehicle in motion if, for example, they: Rrelease the parking brake. Rshift the automatic transmission out of
parking position P.
Rshift the manual transmission into neutral. Rstart the engine. There is a risk of an accident and injury. When leaving the vehicle, always take the key with you and lock the vehicle. Never leave children or animals unattended in the vehicle. Always keep the key out of reach of children. G WARNING If persons (particularly children) are exposed to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never leave persons (particularly children) unatten- ded in the vehicle. G WARNING If the child restraint system is placed in direct sunlight, the parts could become very hot. Children could be suffer burns by touching these parts, in particular on the metallic parts of the child restraint system. There is a risk of injury. If you and your child leave the vehicle, always make sure that the child restraint system is not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has been exposed to direct sunlight, leave it to cool down before securing the child in it. Never leave children unattended in the vehi- cle.
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. In order to correctly secure the child in the child restraint system, always comply with the child restraint system manufactur- er's installation instructions. You should pref- erably 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 59). 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 front airbag is not dis- abled: Ra child secured in a child restraint system on the front-passenger seat could be seri- ously or 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 front 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.

ISOFIX is a standardised securing system for specially designed child restraint systems on the rear seats. Securing rings : for two ISO- FIX child restraint systems are fitted on the left and right of the rear seats.
Top Tether Important safety notes G WARNING Always engage the rear seat backrests in an upright position before installing the Top Tether belt. Push and pull the rear seat backr- ests to check whether they are engaged cor- rectly. The rear seat backrest may fold down if it is not engaged correctly. The child restraint system is then no longer supported correctly or held in position and can no longer perform its intended function. This can cause serious or even fatal injuries.
When fitting a child restraint system, be sure to observe the manufacturer's installation instructions and the instructions for correct use of the child restraint system. 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 securing a child restraint system, always observe the manu- facturer's installation instructions and the correct use of the child restraint system. For safety reasons, on the rear seats use only child restraint systems with an ISOFIX child seat securing system which have been tested and approved for Mercedes-Benz vehicles. An incorrectly fitted child restraint system could come loose and seriously or even fatally injure the child or other vehicle occupants. When fitting the child restraint system, always make sure that it is engaged correctly in the ISOFIX securing rings on both sides.
! When fitting the ISOFIX child restraint
system, make sure that the seat belt for the centre seat does not get trapped. Other- wise, the seat belt could be damaged.
