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

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 25

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 26

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.

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 27

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

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 fault 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 30

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 vehicle convenience 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. a smartphone, USB flash

drive or MP3 player). If this data is stored in the vehicle, you can delete it at any time. This data is sent to third parties only at your request, par‐ ticularly 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 31

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 the responsibility of the provider in question and subject to that provider's data protection conditions and terms of use. The manufacturer has no influence on the content exchanged.

For this reason, please ask the service provider for information about the type, extent and pur‐ pose of the collection and use of personal data when services are provided by third parties.

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 32

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. Tampering 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.

Reduced restraint system protection

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 modify the vehicle to accom‐ modate a person with disabilities, contact an authorized Mercedes-Benz Center for details.

USA only: for details, contact our Customer Assistance Center on 1-800-FOR-MERCedes (1‑800‑367‑6372).

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 Tensioning 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 36

Occupant safety

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

Component Detected deploy‐

ment situation

Front Emergency Ten‐ sioning Devices

Frontal impact, rear impact, side impact, rollover

Rear Emergency Ten‐ sioning Devices

Driver's airbag, front

Frontal impact, rear impact, rollover

Frontal impact

passenger airbag

Knee airbag Frontal impact

Side airbag Side impact

Window curtain air‐ bag

Side impact, rollover, frontal impact

The front passenger 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 airbag is correct (/ page 44).

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. Ta ke 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.

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.

Page 37

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 89).

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‐

Occupant safety

tions for loading the vehicle when securing objects, luggage or loads (/ page 102).

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 54).

If children are traveling in the vehicle, be sure to observe the instructions and safety notes on "Children in the vehicle" (/ page 49).

Reduced seat belt protection

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.

Page 38

Occupant safety

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 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.

Modified Emergency Tensioning 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 which 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‐

Page 39

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.

Releasing the rear passenger compartment center seat belt

If the left-hand rear seat backrest is folded down and back up again, it may not be possible to pull out the rear passenger compartment center seat belt. The seat belt must be released.

Pull the seat belt out approximately 1 in (25 mm) at the seat belt outlet on the seat backrest and then release it again. The seat belt is retracted and released.

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.

Occupant safety

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.

Page 42

Occupant safety

the journey, that the status of the front passenger airbag is correct (/ page 44).

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 89).

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 43

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 49).

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 provided by 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 39).

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 44

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 airbag shutoff

The automatic front passenger airbag shutoff is able to detect whether the front passenger seat is occupied by a person or a child restraint sys‐ tem. The front passenger airbag is enabled 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 48).

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.

Page 45

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 34).

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 airbag may otherwise be disabled by mistake, for example in the following 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.

Occupant safety

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 airbag shutoff self-test. The PASSENGER AIR BAG indicator lamps display the status of the front passenger airbag.

Always observe the notes on the function of the PASSENGER AIR BAG indicator lamps (/ page 44).

Page 46

Occupant safety

Function of the PASSENGER AIR BAG indica‐ tor lamps

Self-test of automatic front passenger 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 airbag is dis‐ played 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 airbag is able to deploy in the event of an accident.

PASSENGER AIR BAG OFF lights up continu‐ ously: the front passenger airbag is disabled. 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 airbag. The PASSENGER AIR BAG OFF indicator 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 airbag 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 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 47

Occupant safety

NEVER use a rearward-facing child restraint system on a seat protected by an ENABLED FRONT AIRBAG in front of it, DEAT H 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 59).

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 59).

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 airbag is enabled.

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

Page 48

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 59).

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 49

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‐

Occupant safety

celed automatically when the vehicle pulls away.

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

System limits

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

Page 50

Occupant safety

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 49).

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 on the rear seats are generally safer than chil‐ dren secured on 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.

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.

Page 51

Occupant safety

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 55).

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.

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.

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.

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 left and right seat backrests are not engaged and locked in place, this will be shown on the multifunction display of the instrument cluster.

If the center seat backrest is not engaged and locked in place, the red lock verification indica‐ tor will be visible.

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‐

Occupant safety

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.

WARNING Risk of becoming trapped if the seats are adjusted by children

Children could become trapped if they adjust the seats, particularly when unattended.

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

Never leave children unattended in the vehicle.

The seats can be adjusted when the ignition is switched off.

WARNING Risk of becoming trapped when adjusting the seats

When you adjust a seat, you or other vehicle occupants could become trapped, e.g. on the seat guide rail.

When adjusting a seat, make sure that no one has any body parts in the sweep of the seat.

Observe the safety notes on "Airbags" and "Chil‐ dren in the vehicle".

WARNING Risk of accident due to the driver's seat not being engaged

If the driver's seat is not engaged, it could move unexpectedly while the vehicle is in motion.

This could cause you to lose control of the vehicle.

Always make sure that the driver's seat is engaged before starting the vehicle.

WARNING Risk of injury from adjusting the vehicle settings while the vehicle is in motion

You could lose control of the vehicle in the following situations:

if you adjust the driver's seat, the head restraint, the steering wheel or the mirror while the vehicle is in motion

if you fasten your seat belt while the vehi‐ cle is in motion

Before starting the engine: adjust the driver's seat, the head restraint, the steering wheel or the mirror and fasten your seat belt.

Children in particular could accidentally press the electrical seat adjustment buttons and become trapped.

While moving the seats, make sure that hands or other body parts do not get under the lever assembly of the seat adjustment system.

WARNING Risk of injury due to head restraints which are not installed or are adjusted incorrectly

If head restraints are not installed or are adjusted incorrectly, the head restraints can‐ not provide protection as intended.

There is an increased risk of injury in the head and neck area, e.g. in the event of an accident or when braking.

Always drive with the head restraints installed.

Before driving off, make sure for every vehicle occupant that the center of the head restraint supports the back of the head at about eye level.

Do not interchange the head restraints of the front and rear seats. Otherwise, you will not be able to adjust the height and angle of the head restraints correctly.

Adjust the head restraint fore-and-aft position so that it is as close as possible to the back of your head.

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.

NOTE Damage to the seats when moving
