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. You should bear the following in mind: Operating conditions: Ravoid short trips as these increase fuel con-
sumption.
Rmake sure that the tyre pressures are
always correct.
Rdo not carry any unnecessary weight. Rkeep an eye on the vehicle's fuel consump-
tion.
Rremove roof racks once you no longer need
them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should therefore adhere to the service intervals. Ralways have service work 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 with the vehicle
stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.

Operating safety Important safety notes G WARNING All work on the vehicle and, in particular, work relevant to safety or on safety-related sys- tems must be carried out at a qualified spe- cialist workshop. G WARNING Some safety systems only function when the engine is running. You should therefore never switch off the engine when driving. Otherwise, the safety systems of your vehicle may not function correctly and as a result will no lon- ger protect you and other persons as inten- ded. In addition, there is a risk that you may lose control of your vehicle and thus cause an accident. G WARNING Work carried out incorrectly, or alterations made to the vehicle, e.g. re-routing of cables under coverings, could cause the safety sys- tems of your vehicle to stop working properly. The safety systems would thus no longer pro- tect you and other persons as intended. In addition, there is a risk that you may lose con- trol of your vehicle and thus cause an acci- dent. All work and alterations to the vehicle, e.g. installations or modifications, should there- fore be carried out at a qualified specialist workshop. G WARNING If work on electronic equipment and its soft- ware is carried out incorrectly, this equipment could stop working. The electronic systems are networked via interfaces. Tampering with these electronic systems could cause mal-

Data stored in the vehicle Fault data Components which are critical for vehicle operation are equipped with fault data mem- ories as standard. There are also data storage devices which record how vehicle compo- nents have reacted in certain driving situa- tions (e.g. airbag deployment or ESP® inter- vention). This data is used exclusively to: Rassist in the rectification of faults and
defects
Rhelp Mercedes-Benz optimise and develop
vehicle functions
The data cannot be used to trace the vehicle's movements. When your vehicle is serviced by Mercedes- Benz, this technical information can be read out from the fault memory. This is performed by authorised employees of the Mercedes- Benz service network using special diagnos- tic computers. After a fault has been rectified, the informa- tion is deleted from the memory. Other mem- ory data is constantly overwritten.
Other devices that store data Depending on the equipment level, your vehi- cle may feature communications and/or entertainment systems (e.g. navigation devi- ces, telephone systems). These allow you to save and edit data required for the operation of the respective device. Further information on operation (e.g. on deleting data) can be found in the separate operating instructions.

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 25).
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 100).
Rthe seat belt has been fastened properly
(Y page 47).
Rthe airbags can inflate unrestricted if
deployed (Y page 42).
Rthe steering wheel is adjusted properly
(Y page 100).

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. First, the seat belt helps to keep the vehicle occupant in the best position in relation to the airbag. Second, 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 SRS consists of: Rthe SRS warning lamp6
Rairbags Rthe airbag control unit with crash sensors Rbelt tensioners for the front seat belts andthe outer seat belts in the rear
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, 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.
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.

Triggering of belt tensioners, belt force limiters and airbags 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 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 the severity of the accident detec- ted, especially the vehicle deceleration or acceleration, and the apparent type of acci- dent: 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 heads 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 seat bolsters 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. 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.

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. Vehicles with automatic child seat recog- nition in the front-passenger seat: the 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 on the front- passenger seat and the 4 PASSENGER AIRBAG OFF indicator lamp in the centre con- sole does not light up: Ra child restraint system without a trans-
ponder for automatic child seat recognition is fitted, or
Ra child restraint system with a transponder for automatic child seat recognition is not properly fitted.
Driver's kneebag
Driver's kneebag : deploys under the steer- ing column. The driver's kneebag is always deployed along with the driver's front airbag. The driver's kneebag is designed to operate together with the front airbags in frontal impacts if certain thresholds are exceeded. The driver's kneebag operates best in con- junction with correctly positioned and fas- tened seat belts. The driver's kneebag increases protection of the driver 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. G WARNING Sensors to control the airbags are located in the doors. Therefore, do not make any modi- fications to the doors or door trim, e.g. retro-
fitting loudspeakers. Damage to the doors can affect operation of the sidebags.

Front sidebags : and sidebags in the 2nd row of seats ; inflate next to the outer seat cushion. When deployed, the sidebags offer additional protection for the thorax and, on the front seats, the pelvis of 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, or also if the vehicle overturns, and the system deter- mines 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 vehicle on which the impact occurs. The windowbags are integrated into the side of the roof frame and deploy in the area extending from the front door (A-pillar) to the rear side window (D-pillar).

PRE-SAFE® takes pre-emptive measures to protect occupants in certain hazardous sit- uations. PRE-SAFE® intervenes: Rif BAS activates, e.g. in emergency braking
situations
Rif 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
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.
Rvehicles with a multicontour seat: the air pressure in the side bolsters of the back- rest is increased.
Rif the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win- dows 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. On vehicles with mul- ticontour seats, the air pressure in the side bolsters is reduced again. 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.

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.
Fastening seat belts
X Adjust the seat and move the backrest to an almost vertical position (Y page 100). X Pull the seat belt smoothly through belt
sash guide :.
X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of your shoulder and the hip section across your hips.
X Engage belt tongue ; in buckle =.
Seat-belt adjustment: if necessary, the driver's and front-passenger seat belts automatically adjust to the upper body (Y page 48).
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.

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, there may be a warning tone. 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 the driver and the front passenger have fas- tened their seat belts. i For more information on the 7 seat
belt warning lamp, see "Indicator and warn- ing lamps in the instrument cluster, seat belt" (Y page 325).
Rear seat belt status indicator
Example: rear-compartment seat belt status indi- cator The rear-compartment seat belt status indi- cator indicates the rear seat on which the belt is fastened. The status indicator displays peo- ple in the direction of travel. In the example, the passengers on the outer seats in the rear have their seat belts fastened. The ü sym- bol in the multifunction display indicates a fastened seat belt. If a seat belt is not fas- tened or if a seat is not occupied, the ý symbol is displayed.
Occupant safety
49
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 290). 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 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.
X In order to ensure that the pyrotechnic seat
belt tensioners have not been triggered, always have the seat belts checked after an accident. If the belt tensioners have been triggered, they must be replaced.

Children in the vehicle
The seat belts on the following seats have belt tensioners and belt force limiters: Rdriver's and front-passenger seat Rthe outer seats in the second row Rthe seats in the third row 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. 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 for the front seats are synchronised with the front airbags, which take on a part of the deceleration force. This results in the force exerted on the occupant being distributed over a greater area. The belt tensioners can only be activated when: Rthe ignition is switched on. Rthe restraint systems are operational; see
"SRS warning lamp" (Y page 41).
The belt tensioners on the outside seats in the second row and on the seats in the third row are triggered independently 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. The 6 SRS warning lamp lights up.
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 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 that is recommended for Mercedes-Benz vehicles. The child restraint system must be appropri- ate to the age, weight and size of the child. You should preferably fit the child 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.

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.
