Adhere to the service intervals. A regularly serviced vehicle will contrib‐ ute to environmental protection.

Always have maintenance work carried out at a qualified specialist workshop.

Personal driving style:

Do not depress the accelerator pedal when starting the engine.

Do not warm up the engine while the vehicle is stationary.

Drive carefully and maintain a suitable distance from the vehicle in front.

Avoid frequent, sudden acceleration and braking.

Change gear in good time and use each gear only up to Ô of its maximum engine speed.

Switch off the engine in stationary traf‐ fic, e.g. by using the ECO start/stop function.

Drive fuel-efficiently. Observe the ECO display for a fuel-efficient driving style.

ENVIRONMENTAL NOTE Environmental

pollution caused by irresponsible dis‐ posal of the high-voltage battery

A high-voltage battery contains materials which are harmful to the environment.

Dispose of defective high-voltage bat‐ teries at a qualified specialist work‐ shop.

Environmental issues and recommendations:

It is recommended that you re-use or recycle materials instead of just disposing of them.

The relevant environmental guidelines and regu‐ lations serve to protect the environment and must be strictly observed.

Possible danger due to substances hazard‐ ous to health

In compliance with Proposition 65 ("Prop65"), the following detachable label has been added to each vehicle sold in California:

Operating safety

WARNING Risk of accident due to mal‐ functions or system failures

If you do not have the prescribed service/ maintenance work or any required repairs carried out, this could result in malfunctions or system failures.

Always have the prescribed service/ maintenance work as well any required repairs carried out at a qualified spe‐ cialist workshop.

WARNING Risk of accident and injury as a result of incorrect modifications to electronic component parts

Modification to electronic components, their software or wiring could impair their function and/or the function of other networked com‐ ponent parts. In particular, systems relevant to safety could also be affected.

As a result, they may no longer function as intended and/or endanger the operating safety of the vehicle.

Never tamper with the wiring and elec‐ tronic component parts or their soft‐ ware.

You should have all work on electrical and electronic components carried out at a qualified specialist workshop.

Observe the "On-board electronics" section in "Technical data".

Page 28

General notes

WARNING Risk of fire due to flammable materials on hot parts of the exhaust system

Flammable material such as leaves, grass or twigs may ignite if they come into contact with hot parts of the exhaust system.

When driving on unpaved roads or offroad, regularly check the vehicle under‐ side.

Remove trapped plants or other flam‐ mable material.

If there is damage, consult a qualified specialist workshop immediately.

NOTE Damage to the vehicle

In the following situations, in particular, there is a risk of damage to the vehicle:

The vehicle becomes grounded, e.g. on a high curb or an unpaved road

The vehicle is driven too fast over an obstacle, e.g. a curb, speed bump or pot‐ hole

A heavy object strikes the underbody or chassis components

In situations such as this, the body, the underbody, chassis components, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, may not absorb the loads that arise as intended.

If the underbody paneling is damaged, flam‐ mable materials such as leaves, grass or twigs can collect between the underbody and the underbody paneling. These materials may ignite if they come into contact with hot parts on the exhaust system.

Have the vehicle checked and repaired immediately at a qualified specialist workshop.

If driving safety is impaired while con‐ tinuing your journey, pull over and stop the vehicle immediately in accordance with the traffic conditions, and contact a qualified specialist workshop.

Vehicles with a 48 V on-board electrical sys‐ tem (EQ Boost technology)

DANGER Risk of fatal injury by touching damaged high-voltage components

Vehicles with a 48 V on-board electrical sys‐ tem contain individual high-voltage compo‐ nents. These high-voltage components are under high voltage.

If you modify component parts of these highvoltage components or touch damaged com‐ ponent parts, you may be electrocuted.

High voltage components may be damaged in an accident, although the damage may not be visible.

Never perform modifications to compo‐ nent parts of high-voltage components.

Page 29

General notes

Never touch damaged component parts of high-voltage components.

Never touch component parts of highvoltage components after an accident.

Vehicles with a 48 V on-board electrical system contain high voltage components. These compo‐ nents are marked with a high voltage label:

All work on high voltage components must be carried out at a qualified specialist workshop.

Declaration of conformity for wireless vehi‐ cle components

ply with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) These devices may not cause harmful interference, and

2) These devices must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment."

Canada: "The wireless devices of this vehicle comply with Industry Canada license-exempt RSS standard(s). Operation is subject to the fol‐ lowing two conditions: (1) These devices may not cause interference, and (2) These devices must accept any interference, including interfer‐ ence that may cause undesired operation of the device."

USA: "Wireless charging system for mobile devi‐ ces (model: WMI2 Wireless Mobile Interface): this device complies with Part 18 of the FCC Rules."

The name and address of the responsible party is:

peiker acustic GmbH Max-Planck-Str. 28-32 61381 Friedrichsdorf Germany

Diagnostics connection

The diagnostics connection is only intended for the connection of diagnostic devices at a quali‐ fied specialist workshop.

WARNING Risk of accident due to con‐ necting devices to the diagnostics con‐ nection

If you connect equipment to a diagnostics connection in the vehicle, it may affect the operation of vehicle systems.

As a result, the operating safety of the vehi‐ cle could be affected.

Only connect equipment to a diagnos‐ tics connection in the vehicle which is

Page 30

General notes

approved for your vehicle by MercedesBenz.

WARNING Risk of accident due to objects in the driver's footwell

Objects in the driver's footwell may impede pedal travel or block a depressed pedal.

This jeopardizes the operating and road safety of the vehicle.

Stow all objects in the vehicle securely so that they cannot get into the driver's footwell.

Always install the floor mats securely and as prescribed in order to ensure that there is always sufficient room for the pedals.

Do not use loose floor mats and do not place floor mats on top of one another.

NOTE Battery discharging from using

devices connected to the diagnostics connection

Using devices at the diagnostics connection drains the battery.

Check the charge level of the battery.

If the charge level is low, charge the battery, e.g. by driving a considerable distance.

Connecting equipment to the diagnostics con‐ nection can lead to emissions monitoring infor‐ mation being reset, for example. This may lead to the vehicle failing to meet the requirements of the next emissions inspection during the main inspection.

Qualified specialist workshop

An authorized Mercedes-Benz Center is a quali‐ fied specialist workshop. It has the necessary special skills, tools and qualifications to cor‐ rectly carry out the work required on your vehi‐

cle. This particularly applies to safety-relevant works.

For the following, always have your vehicle checked at an authorized Mercedes-Benz Cen‐ ter:

safety-relevant works

service and maintenance work

repair work

modifications as well as installations and conversions

work on electronic components

Mercedes‑Benz recommends a Mercedes‑Benz service center.

Data storage

Electronic control units

Electronic control units are installed in your vehi‐ cle. Some of these are necessary for the safe operation of your vehicle, while some assist you when driving (driver assistance systems). In addition, your vehicle provides comfort and

entertainment functions, which are also made possible by electronic control units.

Electronic control units contain data memories which can temporarily or permanently store technical information about the vehicle's operat‐ ing state, component loads, maintenance requirements and technical events or malfunc‐ tions.

In general, this information documents the state of a component part, a module, a system or the surroundings such as:

operating status of system components (e.g. fill levels, battery status, tire pressure)

status messages concerning the vehicle or its individual components (e.g. number of wheel revolutions/speed, longitudinal accel‐ eration, lateral acceleration, display of fas‐ tened seat belts)

malfunctions or faults in important system components (e.g. lights, brakes)

information on events leading to vehicle damage

system reactions in special driving situations (e.g. airbag deployment, intervention of sta‐ bility control systems)

ambient conditions (e.g. temperature, rain sensor)

In addition to providing the actual control unit function, this data assists the manufacturer in detecting and rectifying malfunctions and opti‐ mizing vehicle functions. The majority of this data is temporary and is only processed in the vehicle itself. Only a small portion of the data is stored in the event or malfunction memory.

When your vehicle is serviced, technical data from the vehicle can be read out by service net‐ work employees (e.g. workshops, manufactur‐ ers) or third parties (e.g. breakdown services). Services include repair services, maintenance processes, warranty claims and quality assur‐ ance measures, for example. The read out is per‐ formed via the legally prescribed port for the diagnostics connection in the vehicle. The respective service network locations or third parties collect, process and use the data. They document technical statuses of the vehicle,

Page 33

General notes

assist in finding malfunctions and improving quality and are transmitted to the manufacturer, if necessary. Furthermore, the manufacturer is subject to product liability. For this, the manu‐ facturer requires technical data from vehicles.

Fault memories in the vehicle can be reset by a service outlet as part of repair or maintenance work.

Depending on the selected equipment, you can import data into the vehicle's comfort and info‐ tainment functions yourself.

This includes, for example:

multimedia data such as music, films or pho‐ tos for playback in an integrated multimedia system

address book data for use in connection with an integrated hands-free system or an inte‐ grated navigation system

entered navigation destinations

data about the use of Internet services

This data can be saved locally in the vehicle or it is located on a device which you have connected to the vehicle (e.g. smartphone, USB flash drive

or MP3 player). If this data is stored in the vehi‐ cle, you can delete it at any time. This data is sent to third parties only at your request, partic‐ ularly when you use online services in accord‐ ance with the settings that you have selected.

You can store or change convenience settings/ individualization in the vehicle at any time.

Depending on the equipment, this includes, for example:

settings for the seat and steering wheel posi‐ tions

suspension and climate control settings

customizations such as interior lighting

If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end device to the vehicle. You can control this by means of the control elements integrated in the vehicle. Images and audio from the smartphone can be output via the multimedia system. Cer‐ tain information is simultaneously transferred to your smartphone.

Depending on the type of integration, this can include:

general vehicle data

position data

This allows you to use selected apps on your smartphone, such as navigation or music play‐ back. There is no further interaction between the smartphone and the vehicle; in particular, vehi‐ cle data is not directly accessible. Which type of further data processing occurs is determined by the provider of the specific app used. Which set‐ tings you can make, if any, depends on the spe‐ cific app and the operating system of your smartphone.

Online services

Wireless network connection

If your vehicle has a wireless network connec‐ tion, it enables data to be exchanged between your vehicle and additional systems. The wire‐ less network connection is enabled via the vehi‐ cle's transmission and reception unit or via con‐ nected mobile end devices (e.g. smartphones).

Page 34

General notes

Online functions can be used via the wireless network connection. This includes online serv‐ ices and applications/apps provided by the man‐ ufacturer or other providers.

Manufacturer's services

Regarding online services of the manufacturer, the individual functions are described by the manufacturer in a suitable place (e.g. Operator's Manual, website of the manufacturer) along with the relevant data protection information. Per‐ sonal data may be used for the provision of online services. Data is exchanged via a secure connection, e.g. the manufacturer's designated IT systems. Personal data is collected, pro‐ cessed and used via the provision of services exclusively on the basis of legal permissions or with prior consent.

The services and functions (sometimes subject to a fee) can usually be activated or deactivated. In some cases, this also applies to the entire vehicle's data connection. This excludes, in par‐ ticular, legally prescribed functions and services.

Third party services

If it is possible to use online services from other providers, these services are subject to the data protection and terms of use of the responsible provider. The manufacturer has no influence on the content exchanged.

Please inquire, therefore, about the type, scope and purpose of the collection and use of per‐ sonal data as part of third party services from their respective provider.

MBUX multimedia system/Mercedes me connect

If the vehicle is equipped with the MBUX multi‐ media system or Mercedes me connect, addi‐ tional data about the vehicle's operation, the use of the vehicle in certain situations, and the loca‐ tion of the vehicle may be compiled by the MBUX multimedia system or Mercedes me con‐ nect.

For additional information, please refer to the "MBUX multimedia system" section and/or the Mercedes me connect Terms and Conditions.

Event data recorders

USA only:

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like sit‐ uations, such as an airbag deployment or hitting a road obstacle, data that will assist in under‐ standing how a vehicle's systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.

The EDR in this vehicle is designed to record such data as:

How various systems in your vehicle were operating

Whether or not the driver and front passenger seat belts were buckled/fastened

How far (if at all) the driver was depressing the accelerator and/or brake pedal and

How fast the vehicle was traveling

This data can help provide a better understand‐ ing of the circumstances in which accidents and injuries occur. NOTE: EDR data is recorded by

Page 35

General notes

your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g. name, gender, age and accident location) is recorded. However, other parties, such as law enforcement, could combine EDR data with the type of personally identifying data routinely acquired during a crash investigation.

Access to the vehicle and/or the EDR is needed to read data that is recorded by the EDR, and special equipment is required. In addition to the vehicle manufacturer, other parties that have the special equipment, such as law enforcement, can read the information by accessing the vehi‐ cle or the EDR.

EDR data may be used in civil and criminal mat‐ ters as a tool in accident reconstruction, acci‐ dent claims and vehicle safety. Since the Crash Data Retrieval (CDR) tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC ("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel.

MBUSA will not share EDR data with others with‐ out the consent of the vehicle owner or, if the vehicle is leased, without the consent of the les‐ see. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law.

Warning: the EDR is a component of the Restraint System Module. Ta mpering with, alter‐ ing, modifying or removing the EDR component may result in a malfunction of the Restraint Sys‐ tem Module and other systems.

State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of December 2016, 17 states have enacted laws relating to EDRs.

Occupant safety

Restraint system

Protection by the restraint system

The restraint system includes the following com‐ ponents:

Seat belt system

Airbags

Child restraint system

Child seat securing systems

The restraint system can help prevent the vehi‐ cle occupants from coming into contact with parts of the vehicle interior in the event of an accident. In the event of an accident, the restraint system can also reduce the forces to which the vehicle occupants are subjected.

A seat belt can only provide the best level of pro‐ tection if it is worn correctly. Depending on the detected accident situation, Emergency Tension‐ ing Devices and/or airbags supplement the pro‐ tection offered by a correctly worn seat belt. Emergency Tensioning Devices and/or airbags are not deployed in every accident.

In order for the restraint system to provide the intended level of protection, each vehicle occu‐ pant must observe the following information:

Fasten seat belts correctly.

Sit in an almost upright seat position with their back against the seat backrest.

Sit with their feet resting on the floor, if pos‐ sible.

Always secure persons under 5 ft (1.50 m) tall in an additional restraint system suitable for Mercedes-Benz vehicles.

However, no system available today can com‐ pletely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and airbag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the airbag deploying.

Limited protection from the restraint system

WARNING Risk of injury or death from modifications to the restraint system

The restraint system can no longer function correctly after alterations have been made.

The restraint system may then not protect the vehicle occupants as intended by failing in an accident or triggering unexpectedly, for example

Never alter the parts of the restraint system.

Never tamper with the wiring or any electronic component parts or their software.

If it is necessary to adjust the vehicle to accom‐ modate a person with disabilities, contact an authorized Mercedes-Benz Center for details.

USA only: contact our Customer Assistance Cen‐ ter at 1-800-FOR-MERCedes (1‑800‑367‑6372) for details.

Page 38

Occupant safety

Restraint system functionality

When the ignition is switched on, a self-test is performed, during which the 6 restraint sys‐ tem warning lamp lights up. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are then functional.

Malfunctioning restraint system

A malfunction has occurred in the restraint sys‐ tem if:

The 6 restraint system warning lamp does not light up when the ignition is switched on

The 6 restraint system warning lamp lights up continuously or repeatedly during a journey

WARNING Risk of injury due to malfunc‐ tions in the restraint system

If the restraint system is malfunctioning, restraint system components may be trig‐

gered unintentionally or may not deploy as intended during an accident. This may affect the Emergency Te nsioning Devices or air‐ bags, for example.

Have the restraint system checked and repaired immediately at a qualified spe‐ cialist workshop.

Function of the restraint system in an acci‐ dent

How the restraint system works is determined by the severity of the impact detected and the type of accident anticipated:

Frontal impact

Rear impact

Side impact

Rollover

The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is preemptive in nature. The triggering/deployment of

the components of the restraint system must take place in good time at the start of the colli‐ sion.

Factors which can only be seen and measured after a collision has occurred do not play a deci‐ sive role in the deployment of an airbag. Nor do they provide an indication of airbag deployment.

The vehicle may be deformed significantly with‐ out an airbag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of vehicle deceleration is not high. Conversely, an airbag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, for exam‐ ple, this may result in sufficiently high levels of vehicle deceleration.

Page 39

Occupant safety

The components of the restraint system can be activated or deployed independently of each other:

Component Detected deploy‐

ment situation

Emergency Tension‐ ing Devices

Frontal impact, rear impact, side impact, rollover

Driver's airbag, front

Frontal impact passenger front air‐ bag

Knee airbag Frontal impact

Side airbag Side impact

Window curtain air‐ bag

PRE-SAFE®Impulse

Side impact, rollover,

frontal impact

Side impact Side

The front passenger front airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is off. If the front

passenger seat is occupied, make sure, both before and during the journey, that the status of the front passenger front airbag is correct (/ page 47).

WARNING Risk of burns from hot air bag components

The air bag parts are hot after an air bag has been deployed.

Do not touch the air bag parts.

Have a deployed air bag replaced at a qualified specialist workshop as soon as possible.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, partic‐ ularly if an Emergency Tensioning Device is trig‐ gered or an airbag deployed.

If the Emergency Tensioning Devices are trig‐ gered or an airbag is deployed, you will hear a bang, and a small amount of powder may also be released:

The bang will not generally affect your hear‐ ing.

In general, the powder released is not haz‐ ardous to health but may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions.

Provided it is safe to do so, leave the vehicle immediately or open the window in order to prevent breathing difficulties.

Airbags and pyrotechnic Emergency Tensioning Devices contain perchlorate material, which may require special handling or environmental pro‐ tection measures. National guidelines regarding waste disposal must be observed. In California, see http://www.dtsc.ca.gov/HazardousWaste/ Perchlorate/index.cfm.

Occupant safety

Seat belts

Protection provided by the seat belt

Always fasten your seat belt correctly before starting a journey. A seat belt can only provide the best level of protection if it is worn correctly.

WARNING Risk of injury or death due to incorrectly fastened seat belt

If the seat belt is not worn correctly, it can‐ not perform its intended protective function.

In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly.

Always ensure that all vehicle occu‐ pants have their seat belts fastened correctly and are sitting properly.

Always observe the instructions about the cor‐ rect driver's seat position and adjusting the seats (/ page 95).

In order for the correctly worn seat belt to pro‐ vide the intended level of protection, each vehi‐ cle occupant must observe the following infor‐ mation:

The seat belt must not be twisted and must fit tightly and snugly across the body.

The seat belt must be routed across the cen‐ ter of the shoulder and as low down across the hips as possible.

The shoulder section of the seat belt should not touch your neck nor be routed under your arm or behind your back.

Avoid wearing bulky clothing, e.g. a winter coat.

Push the lap belt down as far as possible across your hips and pull tight with the shoul‐ der section of the belt. Never route the lap belt across your abdomen.

Pregnant women must also take particular care with this.

Never route the seat belt across sharp, poin‐ ted, abrasive or fragile objects.

Only one person may use each seat belt at any one time. Infants and children must never travel sitting on the lap of a vehicle occupant.

Never secure objects with a seat belt if the seat belt is being used by one of the vehi‐ cle's occupants. Always observe the instruc‐ tions for loading the vehicle when securing objects, luggage or loads (/ page 11 4).

Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.

The seat belts on the following seats are equip‐ ped with a special seatbelt retractor:

Co-driver seat

Rear seats

Activate or deactivate the special seatbelt retractor of the seat belt (/ page 58).

If children are traveling in the vehicle, be sure to observe the instructions and safety notes on "Children in the vehicle" (/ page 52).

Page 41

Occupant safety

Limitations of the protection provided by the seat belt

WARNING Risk of injury or death due to incorrect seat position

The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position.

When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdominal or neck injuries, for exam‐ ple.

Adjust the seat properly before begin‐ ning your journey.

Always ensure that the seat backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the center of your shoul‐ der.

WARNING Risk of injury or death when additional restraint systems are not used for persons with a smaller build

Persons under 5 ft (1.50 m) tall cannot wear the seat belt correctly without a suitable additional restraint system.

If the seat belt is not worn correctly, it can‐ not perform its intended protective function. In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly.

Always secure persons under 5 ft (1.50 m) tall in a suitable restraint sys‐ tem.

WARNING Danger of injury or death due to blocked seat belt anchorages

The restraint effect of the seat belt is impaired if objects between the front seat and the door are blocking the movable seat belt anchorage on the front seat.

The seat belt may not then provide the proper protection.

Before starting a journey, make sure that there are no objects between the front seat and the door.

WARNING Risk of injury or death due to damaged or modified seat belts

Seat belts cannot provide protection in the following situations:

The seat belt is damaged, has been modi‐ fied, is extremely dirty, bleached or dyed

The seat belt buckle is damaged or extremely dirty

Modifications have been made to the Emergency Tensioning Device, seat belt anchorage or seat belt retractor

Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters.

Modified or damaged seat belts could tear or fail in the event of an accident, for example.

Page 42

Occupant safety

Modified Emergency Te nsioning Devices may be deployed unintentionally or not function as intended.

Never modify the seat belts, Emergency Tensioning Devices, seat belt ancho‐ rages or seat belt retractors.

Make sure that the seat belts are not damaged, are not worn and are clean.

Always have the seat belts checked immediately after an accident at a qualified specialist workshop.

Only use seat belts that have been approved for your vehicle by Mercedes-Benz.

WARNING Risk of injury or death from deployed pyrotechnic Emergency Ten‐ sioning Devices

Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer opera‐ tional and are unable to perform their inten‐ ded protective function.

Therefore, have deployed pyrotechnic Emergency Tensioning Devices immedi‐

ately replaced at a qualified specialist workshop.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident.

NOTE Damage caused by trapping the

seat belt

If an unused seat belt is not fully retracted, it may become trapped in the door or in the seat mechanism.

Always ensure that an unused seat belt is fully retracted.

Fastening and adjusting the seat belts

If the seat belt is pulled quickly or sharply, the seat belt retractor locks. The seat belt strap can‐ not be pulled out any further.

Always engage seat belt tongue 2 of the seat belt into seat belt buckle 1 of the cor‐ responding seat.

Press and hold the seat belt outlet release and slide seat belt outlet 3 into the desired position.

Let go of the seat belt outlet release and ensure that seat belt outlet 3 locks into position.

Page 45

Occupant safety

the front passenger front airbag is correct (/ page 47).

NOTE Important points to remember if

the front passenger seat is unoccupied

In an accident, the components of the restraint system may deploy unnecessarily on the front passenger side if:

There are heavy objects on the front passenger seat.

The seat belt tongue is engaged in the seat belt buckle of the front passenger seat and the front passenger seat is unoccupied.

Stow objects in a suitable place.

Only one person should use each seat belt at any one time.

Depending on the detected accident situation, the window curtain airbag on the front passenger side may deploy. The airbag is deployed regardless of whether the front passenger seat is occupied.

Protection by the airbags

Depending on the accident situation, an airbag may supplement the protection offered by a cor‐ rectly fastened seat belt.

WARNING Risk of injury or death due to incorrect seat position

If you deviate from the correct seat position, the airbag cannot perform its intended pro‐ tective function and deployment may even cause further injuries.

In order to avoid risks, each vehicle occupant must always make sure of the following:

Fasten seat belts correctly. Pregnant women must take particular care to ensure that the lap belt never lies across the abdomen.

Adopt the correct seat position and keep as far away as possible from the airbags.

Observe the following information.

Always make sure that there are no objects between the airbag and vehicle occupant.

To avoid the risks resulting from the deployment of an airbag, each vehicle occupant must observe the following information in particular:

Before starting your journey, adjust your seat correctly; the driver's seat and front passenger seat should be moved as far back as possible.

When doing so, always observe the informa‐ tion on the correct driver's seat position (/ page 95).

Only hold the steering wheel by the steering wheel rim. This allows the airbag to be fully deployed.

Always lean against the seat backrest when the vehicle is in motion. Do not lean forwards or against the door or side window. You may otherwise be in the deployment area of the airbags.

Always keep your feet on the floor. Do not put your feet on the cockpit, for example.

Page 46

Occupant safety

Your feet may otherwise be in the deploy‐ ment area of the airbag.

If children are traveling in the vehicle, observe the additional notes (/ page 52).

Always stow and secure objects correctly.

Objects in the vehicle interior may prevent an airbag from functioning correctly. Each vehicle occupant must always make sure of the follow‐ ing in particular:

There are no people, animals or objects between the vehicle occupants and an air‐ bag.

There are no objects between the seat, door and door pillar (B-pillar).

There are no hard objects, e.g. coat hangers, hanging on the grab handles or coat hooks.

There are no accessory parts, such as mobile navigation devices, mobile phones or cup holders, attached to the vehicle within the deployment area of an airbag, e.g. on the cockpit, on the door, on the side window or on the side wall trim.

In addition, no connecting cables, tensioning straps or retaining straps must be routed or attached to the vehicle within the deploy‐ ment area of an airbag. Always comply with the accessory manufacturer's installation instructions and, in particular, the notes on suitable places for installation.

There are no heavy, sharp-edged or fragile objects in the pockets of your clothing. Store such objects in a suitable place.

Limited protection from airbags

WARNING Risk of injury due to modifi‐ cations to the airbag cover

If you modify the cover of an airbag or affix objects such as stickers to it, the airbag may no longer function correctly.

Never modify the cover of an airbag and do not affix objects to it.

The installation location of an airbag is identified by the AIRBAG symbol (/ page 42).

WARNING Risk of injury or death due to the use of unsuitable seat covers

Unsuitable seat covers can obstruct or pre‐ vent the deployment of air bags integrated into the seats.

Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, operation of the automatic front passenger air bag shutoff may be restricted.

You should only use seat covers that have been approved for the correspond‐ ing seats by Mercedes-Benz.

WARNING Risk of injury due to malfunc‐ tions of the sensors in the door paneling

Sensors to control the airbags are located in the doors. Modifications or work not per‐ formed correctly to the doors or door panel‐ ing, as well as damaged doors, can lead to the function of the sensors being impaired. The airbags might therefore not function properly any more.

Page 47

Occupant safety

Consequently, the airbags cannot protect vehicle occupants as they are designed to do.

Never modify the doors or parts of the doors.

Always have work on the doors or door paneling carried out at a qualified spe‐ cialist workshop.

WARNING Risk of injury due to deployed airbag

A deployed airbag no longer has a protective function and cannot protect as intended in the event of an accident.

Have the vehicle towed to a qualified specialist workshop in order to have the deployed airbag replaced.

Have deployed airbags replaced immediately.

Status of the front passenger front airbag

Function of the automatic front passenger front airbag shutoff

The automatic front passenger front airbag shut‐ off is able to detect whether the front passenger seat is occupied by a person or a child restraint system. The front passenger front airbag is ena‐ bled or disabled accordingly.

When installing a child restraint system on the front passenger seat, always make sure of the following:

Ensure that the child restraint system is posi‐ tioned correctly (/ page 51 ).

Always observe the child restraint system manufacturer's installation instructions.

Never place objects, e.g. cushions, under or behind the child restraint system.

Fully retract the seat cushion length adjust‐ ment.

The entire base of the child restraint system must always rest on the seat cushion of the front passenger seat.

The backrest of the forward-facing child restraint system must lie as flat as possible against the backrest of the front passenger seat.

The child restraint system must not touch the roof or be put under strain by the head restraints. Adjust the seat backrest inclina‐ tion and the head restraint setting accord‐ ingly.

WARNING Risk of injury or death due to objects between the sitting surface and the child restraint system

Objects between the sitting surface and the child restraint system could affect the func‐ tion of the automatic front passenger airbag shutoff.

This could result in the front passenger air‐ bag not functioning as intended during an accident.

Do not place any objects between the sitting surface and the child restraint system.

The entire base of the child restraint system must always rest on the sitting surface of the front passenger seat.

The backrest of the forward-facing child restraint system must, as far as possi‐ ble, be resting on the seat backrest of the front passenger seat.

Always comply with the child restraint system manufacturer's installation instructions.

A person on the front passenger seat must observe the following information:

Fasten seat belts correctly (/ page 38).

Sit in an almost upright seat position with their back against the seat backrest.

Sit with their feet resting on the floor, if pos‐ sible.

The front passenger front airbag may otherwise be disabled by mistake, for example in the fol‐ lowing situations:

The front passenger transfers their weight by supporting themselves on a vehicle armrest.

The front passenger sits in such a way that their weight is raised from the sitting sur‐ face.

WARNING Risk of injury or death due to deactivated front passenger airbag

If the PASSENGER AIR BAG OFF indicator lamp is lit, the front passenger airbag is disa‐ bled. It will not be deployed in the event of an accident and cannot perform its intended protective function.

A person in the front passenger seat could then, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit.

If the front passenger seat is occupied, always ensure that:

The classification of the person in the front passenger seat is correct and the front passenger airbag is enabled or disa‐ bled in accordance with the person in the front passenger seat.

The front passenger seat has been moved as far back as possible.

The person is seated correctly.

Ensure, both before and during the jour‐ ney, that the status of the front passenger airbag is correct.

If the front passenger seat is occupied, the clas‐ sification of the person or child restraint system on the front passenger seat takes place after the front passenger front airbag shutoff self-test. The PASSENGER AIR BAG indicator lamps dis‐ play the status of the front passenger front air‐ bag.

Always observe the notes on the function of the PASSENGER AIR BAG indicator lamps (/ page 47).

Page 49

Occupant safety

Function of the PASSENGER AIR BAG indica‐ tor lamps

Self-test of automatic front passenger front airbag shutoff

When the ignition is switched on, a self-test is performed during which the two PASSENGER AIR BAG ON and OFF indicator lamps light up simultaneously.

The status of the front passenger front airbag is displayed after the self-test:

PASSENGER AIR BAG ON lights up for 60 seconds, subsequently both indicator lamps are off (PASSENGER AIR BAG ON and OFF): the front passenger front airbag is able to deploy in the event of an accident.

PASSENGER AIR BAG OFF lights up continu‐ ously: the front passenger front airbag is dis‐ abled. It will then not be deployed in the event of an accident.

If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front passenger front airbag. The PASSENGER AIR BAG OFF indi‐ cator lamp may be lit continuously or be off.

If the PASSENGER AIR BAG OFF indicator lamp and the 6 restraint system warning lamp light up simultaneously, the front passenger seat may not be used. Also in this case, do not install a child restraint system on the front passenger seat. Have automatic front passenger front air‐ bag shutoff checked and repaired immediately at a qualified specialist workshop.

Status display

If the front passenger seat is occupied, ensure, both before and during the journey, that the sta‐ tus of the front passenger front airbag is correct for the current situation.

After installing a rearward-facing child restraint system on the front passenger seat: PASSENGER AIR BAG OFF must be lit con‐

tinuously.

WARNING Risk of injury or death from using a rearward-facing child restraint system when the front passenger front airbag is enabled

If you secure a child in a rearward-facing child restraint system on the front passenger seat and the PASSENGER AIR BAG OFF indi‐ cator lamp is off, the front passenger airbag can deploy in the event of an accident.

The child could be struck by the airbag. Always ensure that the front passenger air‐

bag is deactivated. The PASSENGER AIR BAG OFF indicator lamp must be lit.

Page 50

Occupant safety

NEVER use a rearward-facing child restraint system on a seat protected by an ENABLED FRONT AIRBAG in front of it, DEATH or SERI‐ OUS INJURY to the CHILD can occur.

When installing a child restraint system on the front passenger seat, observe the vehicle-spe‐ cific information (/ page 64).

Depending on the child restraint system and the stature of the child, the PASSENGER AIR BAG OFF indicator lamp may be off. In this case, do not install the rearward-facing child restraint system on the front passenger seat.

Instead, install the rearward-facing child restraint system on a suitable rear seat.

After installing a forward-facing child restraint system on the front passenger seat: depending on the child restraint system

and the stature of the child, PASSENGER AIR BAG OFF may be lit continuously or be off. Always observe the following information.

WARNING Risk of injury or death due to incorrect positioning of the forwardfacing child restraint system

If you secure a child in a forward-facing child restraint system on the front passenger seat and you position the front passenger seat too close to the cockpit, in the event of an acci‐ dent, the child could:

Come into contact with the vehicle inte‐ rior if the PASSENGER AIR BAG OFF indi‐ cator lamp is lit, for example.

Be struck by the air bag if the PASSENGER AIR BAG OFF indicator lamp is off.

Always move the front passenger seat as far back as possible and fully retract the seat cushion length adjustment. Always make sure that the shoulder belt strap is correctly routed from the seat belt outlet on the vehicle to the shoul‐ der belt guide on the child restraint sys‐ tem. The shoulder belt strap must be routed forwards and downwards from the vehicle belt outlet. If necessary,

adjust the seat belt outlet and the front passenger seat accordingly.

Always observe the child restraint sys‐ tem manufacturer's installation instruc‐ tions.

When installing a child restraint system on the front passenger seat, observe the vehicle-spe‐ cific information (/ page 64).

If a person is sitting on the front passenger seat: PASSENGER AIR BAG OFF may be lit con‐

tinuously or be off, depending on the person's stature.

A person on the front passenger seat must always observe the following information:

If the front passenger seat is occupied by an adult or a person with a stature correspond‐ ing to that of an adult, the PASSENGER AIR BAG OFF indicator lamp must be off. This indicates that the front passenger front air‐ bag is enabled.

If the PASSENGER AIR BAG OFF indicator lamp is lit continuously, an adult or person

Page 51

Occupant safety

with a build corresponding to that of an adult should not use the front passenger seat.

Instead, they should use a rear seat.

If the front passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), the PASSENGER AIR BAG OFF indicator lamp either lights up continuously or remains off, depending on the result of the classification.

If the PASSENGER AIR BAG OFF indicator lamp is off: move the front passenger seat as far back as possible, or the per‐ son of smaller stature should use a rear seat.

If the PASSENGER AIR BAG OFF indicator lamp is lit continuously: the person of smaller stature should not use the front passenger seat.

WARNING Risk of injury or death when the PASSENGER AIR BAG OFF indicator lamp is lit

If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front passenger air bag is deactivated. It will not be deployed in the event of an acci‐ dent. In this case, the front passenger air bag cannot perform its intended protective func‐ tion, e.g. when a person is seated in the front passenger seat.

That person could, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit.

If the front passenger seat is occupied, always ensure that:

The classification of the person in the front passenger seat is correct and the front passenger air bag is enabled or deactivated in accordance with the per‐ son in the front passenger seat.

The person is seated properly with a cor‐ rectly fastened seat belt.

The front passenger seat has been moved as far back as possible.

Be sure to also observe the following further related subjects:

Child restraint system on the front passenger seat (/ page 64).

PRE-SAFE®system

PRE-SAFE®(anticipatory occupant protec‐ tion)

PRE-SAFE®is able to detect certain critical driv‐ ing situations and implement pre-emptive meas‐ ures to protect the vehicle occupants.

PRE-SAFE®can implement the following meas‐ ures independently of each other:

Tightening the seat belts on the driver's seat and front passenger seat.

Closing the side windows.

Page 52

Occupant safety

Vehicles with sliding sunroof: Closing the sliding sunroof.

Vehicles with memory function: Moving the front passenger seat to a more favorable seat position.

Vehicles with multicontour seat: Increas‐ ing the air pressure in the seat side bolsters of the seat backrest.

PRE-SAFE®Sound: provided that the multi‐ media system is switched on, generates a brief noise signal to stimulate the innate pro‐ tective mechanism of a person's hearing.

NOTE Damage caused by objects in the

footwell or behind the seat

The automatic adjustment of the seat posi‐ tion may result in damage to the seat and/or the object.

Stow objects in a suitable place.

Reversing the PRE-SAFE®system measures

If an accident did not occur, the pre-emptive measures that were taken are reversed.

You will need to perform certain settings your‐ self.

If the seat belt pre-tensioning is not reduced, move the seat backrest back slightly. The locking mechanism releases.

Function of PRE-SAFE®PLUS (anticipatory occupant protection plus)

PRE-SAFE®PLUS can detect certain impacts, particularly an imminent rear impact, and take pre-emptive measures to protect the vehicle occupants. These measures cannot necessarily prevent an imminent impact.

PRE-SAFE®PLUS can implement the following measures independently of each other:

Tightening the seat belts on the driver's seat and front passenger seat.

Increasing brake pressure when the vehicle is stationary. This brake application is can‐

celed automatically when the vehicle pulls away.

If an accident did not occur, the pre-emptive measures that were taken are reversed.

System limitations

The system will not initiate any action in the fol‐ lowing situations:

when backing up or

when the vehicle is towing a trailer and there is a risk of a rear impact

The system will not initiate any braking applica‐ tion in the following situations:

whilst driving or

when entering or exiting a parking space while using Active Parking Assist

Information on PRE-SAFE®Impulse Side

If an imminent side impact is detected, PRESAFE®Impulse Side can pre-emptively move the

Page 53

Occupant safety

front seat vehicle occupant's upper body towards the center of the vehicle. It does this by rapidly inflating an air cushion in the outer seat side bolster of the seat backrest on the side on which the impact is anticipated. This increases the distance between the door and the vehicle occupant.

If PRE-SAFE®Impulse Side has been deployed or is faulty, the PRE-SAFE Impulse Side Inoperative

Safely transporting children in the vehicle

Always observe when children are traveling in the vehicle

Also strictly observe the safety notes for the specific situation. In this way you can recog‐ nize potential risks and avoid dangers if chil‐ dren are traveling in the vehicle (/ page 52).

Be diligent

Bear in mind that neglecting to secure a child in the child restraint system may have serious con‐ sequences. Always be diligent in securing a child carefully before every journey.

To improve protection for children younger than 12 years old or under 5 ft (1.50 m) in height, Mercedes-Benz recommends you observe the following information:

Always secure the child in a child restraint system suitable for this Mercedes-Benz vehi‐ cle.

The child restraint system must be appropri‐ ate to the age, weight and size of the child.

The vehicle seat must be suitable for instal‐ ling a child restraint system.

Accident statistics show that children secured in the rear seats are generally safer than children secured in the front seats. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.

Generic term "child restraint system"

The generic term child restraint system is used in this Operator's Manual. A child restraint sys‐ tem is, for example:

a baby car seat

a rearward-facing child seat

a forward-facing child seat

a child booster seat with a backrest and seat belt guide

Mercedes-Benz recommends using a child booster seat with a backrest.

The child restraint system must be appropriate to the age, weight and size of the child.

Observing laws and legal requirements

Always observe the legal requirements when using a child restraint system in the vehicle.

Page 54

Occupant safety

Observing standards for child restraint sys‐ tems

All child restraint systems must meet the follow‐ ing standards:

U.S. Federal Motor Vehicle Safety Standards 213 and 225

Canadian Motor Vehicle Safety Standards 213 and 210.2

Confirmation that the child restraint system complies with the standards can be found on an instruction label on the child restraint system. This confirmation can also be found in the instal‐ lation instructions that are included with the child restraint system.

Detecting risks, avoiding danger

Securing systems for child restraint systems in the vehicle

Only use the following securing systems for child restraint systems:

the LATCH-type (ISOFIX) mounting brackets

the vehicle's seat belt system

the Top Tether anchorages

Installing a LATCH-type (ISOFIX) child restraint system is preferred.

Simply attaching to the securing rings on the vehicle can reduce the risk of installing the child restraint system incorrectly.

When securing a child with the integrated seat belt of the LATCH-type (ISOFIX) child restraint system, always comply with the permissible gross weight for the child and child restraint sys‐ tem (/ page 58).

A booster seat may be necessary to achieve proper seat belt positioning for children over 40 lbs (18 kg) in weight or until they reach a height where a three-point seat belt can be installed properly without a booster seat.

Mercedes-Benz recommends a suitable child booster seat with a backrest and seat belt guide.

Advantage of a rearward-facing child restraint system

It is preferable to transport a baby or a small child in a suitable rearward-facing child restraint system. In this case, the child sits in the oppo‐

site direction to the direction of travel and faces backwards.

Babies and small children have comparatively weak neck muscles in relation to the size and weight of their head. The risk of injury to the cer‐ vical spine during an accident can be reduced in a rearward-facing child restraint system.

Always secure a child restraint system cor‐ rectly

WARNING Risk of injury or death caused by incorrect installation of the child restraint system

If the child restraint system is incorrectly installed on a suitable seating position, it cannot perform its intended protective func‐ tion.

The child cannot be restrained in the event of an accident, heavy braking or a sudden change of direction.

Always comply with the manufacturer's installation instructions for the child restraint system and its correct use.

Page 55

Make sure that the entire base of the child restraint system always rests on the sitting surface of the seat.

Never place objects under or behind the child restraint system, e.g. cush‐ ions.

Always use child restraint systems with the original cover designed for them.

Always replace damaged covers with genuine covers.

WARNING Risk of injury or death from unsecured child restraint systems in the vehicle

If the child restraint system is not correctly installed or secured, it could release in the event of an accident, sudden braking or a sudden change in direction.

The child restraint system could be flung around and hit vehicle occupants.

Always install child restraint systems correctly, even when not in use.

Always comply with the child restraint system manufacturer's installation instructions.

Always observe the child restraint system manufacturer's installation and operating instructions as well as the vehicle-specific information:

Install the LATCH-type (ISOFIX) child restraint system on the rear seat (/ page 58).

Secure the child restraint system with the seat belt on the rear seat (/ page 63).

Secure the child restraint system with the seat belt on the front passenger seat (/ page 65). Observe the specific instructions for the rearward-facing and forward-facing child restraint systems (/ page 64).

If the front passenger seat is occupied, ensure, both before and during the jour‐ ney, that the status of the front passenger front airbag is correct for the current situation (/ page 47).

Occupant safety

Observe the warning labels in the vehicle interior and on the child restraint system.

Also secure Top Tether if present.

Do not modify the child restraint system

WARNING Risk of injury due to modifi‐ cations to the child restraint system

The child restraint system may no longer function as it is supposed to if you make modifications or attach objects to it, e.g. toys or unsuitable accessories. This poses an increased risk of injury!

Never modify the child restraint system. Only attach accessories which the manufacturer of the child restraint system has authorized especially for this child restraint system.

Page 56

Occupant safety

Only use child restraint systems which are in proper working condition

WARNING Risk of injury or death caused by the use of damaged child restraint systems

Child restraint systems or their retaining sys‐ tems that have been subjected to a load in an accident may then not be able to perform their intended protective function.

The child cannot be restrained in the event of an accident, heavy braking or a sudden change of direction.

Always replace child restraint systems immediately that have been damaged or involved in an accident.

Have the securing systems for the child restraint systems checked at a qualified specialist workshop before installing a child restraint system again.

Avoiding direct sunlight

WARNING Risk of burns when the child seat is exposed to direct sunlight

If the child restraint system is exposed to direct sunlight or heat, parts could heat up.

Children could suffer burns from these parts, particularly on metallic parts of the child restraint system.

Always make sure that the child restraint system is not exposed to direct sunlight.

Protect it with a blanket, for example.

If the child restraint system has been exposed to direct sunlight, allow it to cool before securing a child into it.

Never leave children unattended in the vehicle.

Observe when stopping or parking

WARNING Risk of accident and injury due to children left unattended in the vehicle

If children are left unattended in the vehicle, they could:

Open doors, thereby endangering other persons or road users.

Get out and be struck by oncoming traf‐ fic.

Operate vehicle equipment and become trapped, for example.

In addition, the children could also set the vehicle in motion, for example by:

Releasing the parking brake.

Changing the transmission position.

Starting the vehicle.

Never leave children unattended in the vehicle.

Page 57

When leaving the vehicle, always take the key with you and lock the vehicle.

Keep the vehicle key out of reach of children.

WARNING Risk of fatal injury due to exposure to extreme heat or cold in the vehicle

Activating/deactivating the seat belt's child special seat belt retractor

WARNING Risk of injury or death if a seat belt is unfastened while the vehicle is in motion

If the seat belt is released while the vehicle is in motion, the child restraint system is no longer correctly secured. The child seat safety feature is deactivated and the seat belt is drawn in a bit by the inertia reel.

It is therefore not possible to engage the seat belt again.

Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions.

Activate the child seat safety feature again and correctly secure the child restraint system.

When enabled, the special seat belt retractor ensures that the seat belts of the front passenger seat and rear seats do not slacken once the child restraint system is secured.

The seat belts on the following seats are equip‐ ped with a special seat belt retractor:

Front passenger seat

Rear seats

To install a child restraint system: when installing a child restraint system, always observe the manufacturer's installation and operating instructions as well as the informa‐ tion in this Operator's Manual.

Pull the seat belt smoothly from the seat belt outlet.

Engage the seat belt tongue in the seat belt buckle.

To activate the special seat belt retrac‐ tor: pull the seat belt out fully and let the

inertia reel retract it again. When the special seat belt retractor is activa‐ ted, you should hear a ratcheting sound.

Push the child restraint system down until the seat belt sits tightly.

To deactivate the special seat belt retrac‐ tor: press the release button of the seat belt

buckle.

Hold the seat belt tongue and guide back to the seat belt outlet.

Installing the LATCH-type (ISOFIX) child restraint system on the rear seat

WARNING Risk of injury if the rear bench seat/rear seat and seat backrest are not engaged

If the rear bench seat/rear seat and seat backrest are not engaged they could fold for‐ wards, e.g. when braking suddenly or in the event of an accident.

If this is the case, the vehicle occupant would be forced into the seat belt by the rear bench seat/rear seat or by the seat backrest. The seat belt cannot protect as intended and could result in additional injury.

Page 61

Occupant safety

Objects or loads in the trunk/cargo com‐ partment cannot be restrained by the seat backrest.

Make sure that the seat backrest and the rear bench seat/rear seat are engaged before every trip.

If the seat backrest is not engaged and locked in place, this will be shown on the multifunction display on the instrument cluster (fold rear seat back electrically) or the red lock verification indi‐ cator will be visible (fold rear seat back man‐ ually).

WARNING Risk of injury or death if the permissible gross mass of the child and child restraint system is exceeded

For LATCH-type (ISOFIX) child restraint sys‐ tems in which the child is secured using the integrated seat belt in the child restraint sys‐ tem, the permissible gross mass of the child and child restraint system is 73 lb (33 kg).

If the child and the child restraint system together weigh more than 73 lb (33 kg), the LATCH-type (ISOFIX) child restraint system with integrated seat belt does not offer suffi‐ cient protection. An excessive load may be placed on the LATCH-type (ISOFIX) child seat attachments and the child may not be restrained in the event of an accident, for example.

If the child and the child restraint sys‐ tem together weigh more than 73 lb (33 kg), use only a LATCH-type (ISOFIX) child restraint system that secures the child with the vehicle seat belt.

Also secure the child restraint system with the Top Tether belt, if available.

Always comply with the information about the mass of the child restraint system:

in the manufacturer's installation and operat‐ ing instructions for the child restraint system used

on a label on the child restraint system, if present

Regularly check that the permissible gross mass of the child and child restraint system is still complied with.

When you are installing a child restraint system, observe the following:

Always observe the correct use of the seats

and consider their suitability for attaching a child restraint system.

Always comply with the manufacturer's

installation and operating instructions for the child restraint system used.

Make sure that the child's feet do not touch

the front seat. If necessary, move the front seat forward slightly.

When installing a LATCH-type (ISOFIX)

child restraint system, observe the following:

When you are using a Group 0/0+ baby

car seat and a Group 1 rearward-facing child restraint system on a rear seat:

adjust the front seat so that the seat does not touch the child restraint system.

Page 62

Occupant safety

When you are using a Group 1 forward-

facing child restraint system: remove the head restraint from the respective seat, if possible. In addition, the seat backrest of the child restraint system must, as far as possible, lie flat against the backrest of the vehicle seat.

After the child restraint system has been removed, replace the head restraints again immediately and adjust them correctly.

When you are using a child restraint sys‐

tem on a seat on the third row of seats:

place the backrest of the second row of seats in the foremost position.

For certain child restraint systems in weight

group 2 or 3, restrictions in the maximum size setting may apply (e.g. due to possible contact with the roof).

The child restraint system must not be ten‐

sioned between the roof and the seat cush‐ ion and/or be installed facing the wrong direction. Where possible, adjust the seat cushion inclination accordingly.

The child restraint system must not be put

under strain by the head restraints. Adjust the head restraints accordingly.

Before every trip, make sure that the LATCHtype (ISOFIX) child restraint system is engaged in both mounting brackets in the vehicle.

NOTE Be careful not to damage the seat

belt for the center seat when installing the child restraint system
