worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
! There is a risk of damage to the vehicle if: R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb or a hole in the road R
a heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the under-
carriage, chassis parts, 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, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch
fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediate ly,
paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop. Declarations of conformity
Vehicle components which receive
and/or transmit radio waves USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-

approved by the party responsible for com-
pliance could void the user’s authority to

Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
G WARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle.
G WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter28
Introduction

The shoulder section of the seat belt must
always be routed across the center of the
shoulder. Adjust the belt outlet if necessary. X
To raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions. X
To lower: hold belt outlet release C and
slide belt outlet downwards. X
Let go of belt outlet release C in the
desired position and make sure that the
belt outlet engages.
All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
( Y
page 61).
Releasing seat belts
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. Basic illustration X

Deployment of Emergency Tensioning
Device s an d air bags
Important safet y notes
G WARNING
The air bag parts are hot after an air bag has
bee n deployed . There is a ris k of injury.
Do no t touch th e air bag parts . Hav e a
deployed air bag replaced at a qualified spe -
cialis t workshop as soo n as possible.
G WARNING
A deployed air bag no longer offers any pro -
tection and canno t provid e th e intended pro -
tection in an accident. There is an increase d
ris k of injury.
Hav e th e vehicle towed to a qualified special-
ist workshop in order to hav e a deployed air
bag replaced.
It is important fo r your safet y and that of your
passenger to hav e deployed air bags replaced
and to hav e any malfunctionin g air bags
repaired. Thi s will hel p to mak e sur e th e air
bags continue to perform their protective
function fo r th e vehicle occupant s in th e
event of a crash .
G WARNING
Pyrotechnic Emergency Tensioning Devices
that hav e bee n deployed are no longer opera-
tional and are unable to perform their inten-
ded protective function . Thi s poses an
increase d ris k of injury or eve n fatal injury.
Therefore, hav e pyrotechni c Emergency Ten -
sioning Devices whic h hav e bee n triggere d
immediately replaced at a qualified specialis t
workshop .
An electric moto r is used by PRE-SAF E ®
to
trigger th e tightenin g of th e seat belt in haz -
ardous situations. Thi s procedur e is reversi-
ble.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed , you will hear a
bang, and a small amount of powder may also be released. The u restrain t system warn -
in g lamp lights up.
Only in rar e cases will th e ban g affec t your
hearing. The powder that is release d gener-
ally doe s no t constitute a health hazard , but it
may caus e short-term breathin g difficulties in
people wit h asthm a or other respirator y prob-
lems. To avoid this, you may wish to get out of
th e vehicle or ope n th e windows as soo n as it
is saf e to do so.
Ai r bags and pyrotechni c Emergency Tension-
in g Devices (ETDs) contain perchlorat e mate-

Safety

Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driv-
er's seat belt, are equipped with a special seat
belt retractor. When activated, the special
seat belt retractor ensures that the seat belt
cannot slacken once the child seat is secured.
Installing a child restraint system: X
Make sure you observe the child restraint
system manufacturer's installation instruc-
tions. X
Pull the seat belt smoothly from the belt
outlet. X
Engage seat belt tongue in belt buckle.
Activating the special seat belt retractor: X
Pull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat
belt retractor is enabled. X
Push the child restraint system down so
that the seat belt is tight and does not
loosen.
Removing the child restraint system and
deactivating the special seat belt retractor: X
Make sure you observe the child restraint
system manufacturer's installation instruc-
tions. X
Press the release button of the seat belt
buckle and guide the seat belt tongue back
towards the belt sash guide.
The special seat belt retractor is deactiva-
te d .
Child restraint system
The use of seat belts and child restraint sys-
tems is required by law in: R
all 50 states R
the U.S. territories R
the District of Columbia R
all Canadian provinces
If you install a rearward-facing child restraint
system on the center rear seat, the rear arm
rest must be folded back as far as possible.
You can obtain further information about the
correct child restraint system from any
authorized Mercedes-Benz Center.
G WARNING
If the child restraint system is installed incor-
rectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained
in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cush-
ion. Never place objects, e.g. cushions, under
or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
G WARNING
If the child restraint system is installed incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik-
ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" ( Y
