Protecting the environment
+
ENVIRONMENTAL NOTE Environmental
damage due to operating conditions and
personal driving style
The pollutant emission of the vehicle is
directly related to the way you operate the
vehicle.
Operate your vehicle in an environmentally
responsible manner to help protect the envi‐
ronment. Please observe the following rec‐
ommendations on operating conditions and
personal driving style.
Operating conditions:
#
Make sure that the tire pressure is cor‐
rect.
#
Do not carry any unnecessary weight
(e.g. roof luggage racks once you no
longer need them).
#
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 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.
Mercedes-Benz Genuine Parts

ENVIRONMENTAL NOTE Environmental
damage caused by not using recycled
reconditioned components
Daimler AG offers recycled reconditioned
components and parts with the same quality
as new parts. The same entitlement from the
Limited Warranty is valid as for new parts.
#
Use recycled reconditioned compo‐
nents and parts from Daimler AG.

You could jeopardize the operating safety of your
vehicle if you use parts, tires and wheels as well
as accessories relevant to safety which have not
been approved by Mercedes-Benz. Safety-rele‐
vant systems, e.g. the brake system, may mal‐
function. Only use Mercedes-Benz Genuine Parts
or parts of equal quality. Only use tires, wheels
and accessories that have been specifically
approved for your vehicle model.
Mercedes-Benz Genuine Parts are subject to
strict quality control. Each part has been spe‐
cially developed, manufactured or selected for
Mercedes-Benz vehicles and fine-tuned for them.
Therefore, only Mercedes-Benz Genuine Parts
should be used.
More than 300,000 different Mercedes-Benz
Genuine Parts are available for Mercedes-Benz
models.
All authorized Mercedes-Benz Centers maintain
a supply of Mercedes-Benz Genuine Parts for
necessary service and repair work. In addition,
strategically located parts delivery centers pro‐
vide for quick and reliable parts service.
Always specify the vehicle identification number
(VIN) (/ page 458) when ordering MercedesBenz Genuine Parts.

NOTE Damage to the vehicle
In the following situations, in particular, there
is a risk of damage to the vehicle:
R
The vehicle becomes grounded, e.g. on a
high curb or an unpaved road
R
The vehicle is driven too fast over an
obstacle, e.g. a curb, speed bump or pot‐
hole
R
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.
or
#
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.

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:
R
Operating status of system components (e.g.
fill levels, battery status, tire pressure)
R
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)
R
Malfunctions or faults in important system
components (e.g. lights, brakes)
R
Information on events leading to vehicle
damage
R
System reactions in special driving situations
(e.g. airbag deployment, intervention of sta‐
bility control systems)
R
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
28
General notes
Page 31
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,
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:
R
Multimedia data such as music, films or pho‐
tos for playback in an integrated multimedia
system
R
Address book data for use in connection with
an integrated hands-free system or an inte‐
grated navigation system
R
Entered navigation destinations
R
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:
R
Settings for the seat and steering wheel posi‐
tions
R
Suspension and climate control settings
R
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:
R
General vehicle data
R
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
General notes
29
Page 32
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).
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
30
General notes
Page 33
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:
R
How various systems in your vehicle were
operating
R
Whether or not the driver and front
passenger seat belts were buckled/fastened
R
How far (if at all) the driver was depressing
the accelerator and/or brake pedal and
R
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
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.
To read data recorded by an EDR, special equip‐
ment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer, other parties that have the special
equipment, such as law enforcement, can read
the information by accessing the vehicle 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.

Restraint system
Protection provided by the restraint system
The restraint system includes the following com‐
ponents:
R
Seat belt system
R
Airbags
R
Child restraint system
R
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:
R
Fasten seat belts correctly.
R
Sit in an almost upright seat position with
their back against the seat backrest.
R
Sit with their feet resting on the floor, if pos‐
sible.
R
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).

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:
R
The 6 restraint system warning lamp
does not light up when the ignition is
switched on
R
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:
R
Frontal impact
R
Rear impact
R
Side impact
R
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.
34
Occupant safety
Page 37
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
passenger airbag
Frontal impact
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 45).
&
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:
R
The bang will not generally affect your hear‐
ing.
R
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 https://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.
Occupant safety
35
Page 38
&
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 seat
(/ 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:
R
The seat belt must not be twisted and must
fit tightly and snugly across the body.
R
The seat belt must be routed across the cen‐
ter of the shoulder and as low down across
the hips as possible.
R
The shoulder section of the seat belt should
not touch your neck nor be routed under
your arm or behind your back.
R
Avoid wearing bulky clothing, e.g. a winter
coat.
R
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.
R
Never route the seat belt across sharp, poin‐
ted, abrasive or fragile objects.
R
Only one person should use each seat belt at
any one time. Never allow babies and chil‐
dren to travel sitting on the lap of another
vehicle occupant.
R
Never secure objects with a seat belt if the
seat belt is also being used by one of the
vehicle's occupants. Always observe the
instructions for loading the vehicle when
securing objects, luggage or loads
(/ page 99).
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:
R
Front passenger seat
R
Rear seats
Activate or deactivate the special seatbelt
retractor (/ 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).

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 Risk of injury or death due to
damaged or modified seat belts
Seat belts cannot provide protection in the
following situations:
R
The seat belt is damaged, has been modi‐
fied, is extremely dirty, bleached or dyed
R
The seat belt buckle is damaged or
extremely dirty
R
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

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:
R
Always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi‐
cle.
R
The child restraint system must be appropri‐
ate to the age, weight and size of the child.
R
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:
R
A baby car seat
R
A rearward-facing child seat
R
A forward-facing child seat
R
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:
R
U.S. Federal Motor Vehicle Safety Standards
213 and 225
R
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:
R
The LATCH-type (ISOFIX) mounting brackets
R
The vehicle's seat belt system
Occupant safety
49
Page 52
R
The To p 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 54).
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 fitted
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.
#
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.

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 seatbelt retractor
ensures that the seat belts of the front
passenger seat and rear seats do not slacken
once the child restraint system is secured.

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

present
Regularly check that the permissible gross mass
of the child and child restraint system is still
complied with.
When installing a child restraint system, observe
the following:
O
Always observe the correct use of the seats
and consider their suitability for attaching a
child restraint system.
O
