• restraint system, consisting of the seat belts and anchorages, belt tensioners, belt force limiters, airbags

• wiring

• networked electronic systems

Airbags or belt tensioners could then fail, e.g. in the event of an accident in which the deceleration force would normally be high enough to trigger the systems, or they could be triggered unintentionally. Never carry out any modifications on the restraint systems. Never tamper with electronic components and their software.

Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required.

Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

In particular, all work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. The operating safety of the vehicle can be affected if this work is carried out incorrectly. There is a risk of accident and injury.

If SRS is malfunctioning, individual systems may be activated unintentionally or not be triggered in the event of an accident with heavy braking.

• does not light up when you switch on the ignition

• does not go out after the engine has been running for a few seconds

• lights up again once the engine is running

In this case, have the SRS checked immediately at a qualified specialist workshop.

If the seat belt tensioners have been triggered, they provide no additional protection in the event of another accident. Therefore, have belt tensioners which have been triggered replaced at a qualified specialist workshop.

Comply with safety regulations when disposing of belt tensioners. Any Mercedes-Benz Service Centre can provide details of these regulations.

Airbags provide additional protection; they are not, however, a substitute for the seat belts.

• Vehicle occupants — in particular pregnant woman — must wear their seat belt correctly at all times and lean back against their backrest, which should be positioned as close to the vertical as possible. The head restraint must support the back of the seat occupant's head at about eye level.

• Always secure children less than 1.50 m tall or under 12 years of age in suitable child restraint systems.

• All 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 middle of the driver's front airbag cover as possible.

• Move the front-passenger seat as far back as possible, in particular, if a child is secured in a child restraint system on the seat.

• Vehicle occupants in particular, children must not lean their head on the area of the window in which a sidebag or head/thorax airbag* is deployed.

• Rearward-facing child restraint systems must not be fitted to the front-passenger seat unless the front-passenger front airbag has been disabled. On the front-passenger seat, the front-passenger front airbag is only deactivated if a child restraint system with automatic child seat recognition is fitted to the front-passenger seat*. The  PASSENGER AIRBAG OFF warning lamp must be lit constantly.

  If either the rearward-facing child restraint system or the front-passenger seat* of your vehicle does not have automatic child seat recognition, 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.

• Make sure there are no heavy or sharp-edged objects in pockets of clothing.

• Do not lean forwards, e.g. over the cover of the driver's front airbag, particularly when the vehicle is in motion.

• Do not put your feet on the dashboard.

• Only hold the steering wheel by the rim. This allows the airbag to inflate fully. You could be injured if the airbag is deployed and you are holding the inside of the steering wheel.

• Do not lean on the doors from inside the vehicle.

• Make sure that there are no people, animals or objects between the vehicle occupants and the area of deployment of the airbag.

• Do not place any objects between the seat backrest and the door.

• Do not hang any hard objects, for example coat hangers, on the grab handles or coat hooks.

• Do not attach accessories, e.g. cup holders, to the doors.

It is not possible to rule out the risk of injuries caused by an airbag due to the high speed at which the airbag is required to deploy.

• Padded steering wheel boss

• Front-passenger front airbag cover

• Outer side of front seats

• Side panel next to the rear seat backrest

When an airbag deploys, a small amount of powder is released. The powdery dust may cause short term breathing difficulties to persons suffering from asthma or pulmonary problems.

In order to prevent possible 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 interior. The powder does not constitute a health hazard and does not indicate that there is a fire in the vehicle.

The airbag parts are hot after the airbag has been triggered. Do not touch them, otherwise you may burn yourself.

Occupants are not protected by the airbags in the event of another accident. Have the airbags checked at a qualified specialist workshop.

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 be equipped with a special tear seam for head/thorax airbags. Otherwise, a head/thorax airbag may not deploy correctly and could fail to provide the intended protection in the event of an accident. These seat covers can be obtained from a Mercedes-Benz Service Centre.

Do not secure any objects (e.g. coat hangers) on the head restraint rods. Otherwise, the active head restraints may not function correctly and could fail to provide the intended protection in the event of an accident.

Do not leave children unsupervised in the vehicle, even if they are secured in a child restraint system. They could be injured on parts of the vehicle. They could be seriously or even fatally injured by prolonged exposure to extreme heat or cold.

Do not expose the child restraint system to direct sunlight. The metallic parts of the child restraint system could heat up and the child could be burned by them.

If the children open a door, they could injure others. They could get out and injure themselves or be injured by a passing vehicle.

• an accident

• a braking manoeuvre

• a sudden change of direction

Do not carry heavy or hard objects inside the vehicle unless they are secured. You will find further information under "Loading guidelines" in the index.

• Children less than 1.50 m tall and under twelve years of age must always be secured in special child restraint systems on a suitable seat. This is necessary because the seat belts are not designed for children.

• Do not secure children under twelve years of age on the front-passenger seat. Exception: the vehicle is fitted with automatic child seat recognition on the front-passenger seat* and the child is secured in a child restraint system with automatic child seat recognition.

• If you fit a child restraint system to the front-passenger seat, you must move the front-passenger seat as far back as possible.

• Never allow children to travel sitting on the lap of another occupant. Due to the forces occurring in the event of an accident, heavy braking or sudden change in direction, it would not be possible to restrain the child. The child would be thrown against parts of the vehicle interior and be seriously or even fatally injured.

If the child restraint system is not fitted correctly to a suitable vehicle seat, it cannot perform its protective function. The child cannot be restrained in the event of an accident, heavy braking or sudden changes of direction. This may lead to serious or even fatal injuries. For this reason, when fitting a child restraint system observe the manufacturer's installation instructions and correct use of the child restraint system.

Child restraint systems should preferably be fitted to the rear seats. The child is generally better protected there.

The entire base of the child restraint system must always be resting on the seat cushion. Never place objects, e.g. a cushion, under the child restraint system.

Only use child restraint systems with their original covers. Only replace damaged covers with genuine Mercedes-Benz covers.

For safety reasons, you should only use child restraint systems which have been approved for use in Mercedes-Benz vehicles.

Vehicles with through-loading feature* in the rear seat backrest: do not fit a rearward-facing child restraint system on the centre rear seat.

• The child secured in a child restraint system on the front-passenger seat could be injured seriously or even fatally if the front-passenger front airbag is deployed in an accident, especially if it is near the front-passenger front airbag when it is triggered.

• You must not secure a child in a rearward-facing child restraint system on the front-passenger seat. Only secure a rearward-facing child restraint system on a suitable rear seat.

• You must move the front-passenger seat to the rearmost position if you wish to secure a child in a forward-facing child restraint system on the front-passenger seat.

• on vehicles without automatic child seat recognition in the front-passenger seat*

• on vehicles with automatic child seat recognition on the front-passenger seat* if there is no child restraint system with automatic child seat recognition fitted to the front-passenger seat.

• if the PASSENGER AIRBAG OFF warning lamp on the centre console is not lit on vehicles with automatic child seat recognition on the front-passenger seat*.

To draw attention to this danger, there is an appropriate warning sticker on the dashboard as well as 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.

If the PASSENGER AIRBAG OFF warning lamp does not light up when the child restraint system is fitted, the front-passenger front airbag has not been disabled. If the front-passenger front airbag is inflated, the child could be seriously or even fatally injured.

• Do not use a rearward-facing child restraint system on the front-passenger seat.

• Fit a rearward-facing child restraint system on a suitable rear seat.

or

• Only use a forward-facing child seat on the front-passenger seat and move the front-passenger seat to its rearmost position.

• Have the automatic child seat recognition checked at a qualified specialist workshop.

To ensure that the automatic child seat recognition on the front-passenger seat functions correctly, never place objects, e.g. a cushion, under the child restraint system. The entire base of the child restraint system must always be resting on the seat cushion. An incorrectly fitted child restraint system cannot perform its intended protective function in the event of an accident, and could even lead to injuries.

• laptops, if switched on

• mobile phones

• cards with transponders, e.g. ski passes or access passes

as signals from electronic equipment can cause interference in the automatic child seat recognition sensor system. This can cause the system to malfunction. It could cause the  PASSENGER AIRBAG OFF warning lamp to light up even when no child seat with automatic child seat recognition has been fitted. The front-passenger front airbag would not be triggered in an accident. It may also be that the  PASSENGER AIRBAG OFF warning lamp does not light up briefly when you turn the key to position 2 in the ignition lock.

A child restraint system secured by the ISOFIX child seat securing system does not provide sufficient protection for children weighing more than 22 kg. For this reason, do not secure children weighing more than 22 kg in a child restraint system secured by the ISOFIX child seat securing system. If the child weighs more than 22 kg, secure the child restraint system using a lap-shoulder belt.

If a child restraint system is not fitted properly to a suitable seat in the vehicle, it cannot provide its protective function. It would not be possible to restrain the child in the event of an accident, sudden braking or a sudden change in direction. The child could be seriously or even fatally injured. For this reason, observe the manufacturer’s installation instructions and correct use when fitting the child restraint system.

On the rear seats, only use child restraint systems with an ISOFIX child seat securing system which have been recommended for use in 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, make sure that it is engaged in the securing rings on both sides.

Please note that child restraint systems cannot provide a protective function if they or their retaining systems are damaged or have been subjected to a load in an accident. The child secured in this system could be injured seriously or even fatally in the event of an accident, sudden braking or a sudden change in direction.

You must therefore have child restraint systems that are damaged or have been subjected to a heavy load in an accident checked immediately along with their anchorages at a qualified specialist workshop.

Make sure that the rear seat backrest is fully locked. The red lock verification indicators on the left and right should no longer be visible. If they are, the rear seat backrests are not locked. If this is the case, occupants could be injured in the event of an accident, e.g. by objects being thrown forwards from the luggage compartment.

• Do not modify the integrated child seat.

• When the child seat is occupied, adjust the head restraint to a position in which the back of the child's head is supported by the centre of the head restraint at about eye level.

• Replace an integrated child seat that has been damaged or subjected to a heavy load as the result of an accident.

• Be aware that children under two years of age require a different child restraint system. Information about other child restraint systems is available from any Mercedes-Benz Service Centre.

• The rear seat backrest in the vehicle must be securely locked in position.

• The shoulder belt section of the seat belt must be routed across the middle of the child's shoulder never across the child's neck and pulled tight against the child's chest. The lap section of the seat belt must be routed across the child's pelvis not across the abdomen and pulled tight against the child's body; retighten the belt strap if necessary.

• Only ever secure one child at a time in the child restraint system.

• The belt must be routed through the hook.

• The belt strap must not be trapped or twisted or rub against sharp edges.

If the padded table has not been fitted to and used correctly on the integrated child seat, the child cannot be restrained in the event of an accident or sudden braking and could be seriously or even fatally injured. For this reason, observe the following description when fitting the padded table.

The padded table is only suitable for use together with the folded-out integrated child seat.

On the rear seats, only use the padded table which is recommended for Mercedes-Benz vehicles.

An incorrectly fitted padded table could come loose and seriously or even fatally injure the child or other vehicle occupants. Fit the padded table and make sure that it is correctly secured.

If the padded table has been damaged or subjected to a load in an accident, the child could be seriously or even fatally injured in the event of an accident, braking or a sudden change in direction.

You must therefore have padded tables that are damaged or have been subjected to a heavy load in an accident checked immediately along with their mountings at a qualified specialist workshop and replaced if necessary.

To reduce the risk of serious or even fatal injury to the child in the event of an accident, braking or sudden change in direction:

• Observe the following description when fitting the padded table.

• Do not modify the padded table.

• When the child seat is occupied, adjust the head restraint to a position in which the back of the child's head is supported by the centre of the head restraint at about eye level.

• Replace a damaged padded table or one that has been subjected to a load in an accident.

• Be aware that children under two years of age or children weighing less than 12.5 kg require a different child restraint system. Information about other child restraint systems is available from any Mercedes-Benz Service Centre.

Do not modify the padded table, integrated child seat and seat belts. The padded table must not be used without a cover. The cover must not be removed from the padded table or replaced with a cover from another manufacturer. Otherwise, the official approval is invalidated and its protective function could be restricted.

Do not subject the padded table to unnecessary heat nor expose it to direct sunlight. Parts of the padded table could heat up and the child could be burnt by the hot parts.

Make sure that:

• the belt is routed as described below

• the belt is not twisted

• the padded table is close to the child's body

• the belt is routed through the hook

• the belt strap is not trapped or twisted, or rubbing against sharp edges

It would not otherwise be possible to restrain the child in the event of an accident, sudden braking or abrupt change in direction and this could result in serious or even fatal injury to the child.

The padded table must be secured in the vehicle correctly or stowed securely in the luggage compartment. It could otherwise become loose in the event of an accident, sudden braking or abrupt change in direction and could injure vehicle occupants or cause damage to the vehicle.

Activate the child-proof locks on the rear doors and deactivate the rear-compartment window controls when children are travelling in the vehicle. The children could otherwise open doors or windows while the vehicle is in motion, injuring themselves and others.
