High-voltage switch-off device
!
The vehicle's high-voltage electrical system
must only be switched off when the vehicle is stationary by specially trained technicians.
The vehicle's high-voltage electrical system
may otherwise be damaged. Your vehicle is equipped with a high-voltage
switch-off device :which can be used to
switch off the vehicle's high-voltage electrical
system.

It is not permitted to retrofit a mobile phone
aerial.
trailer tow hitch !
It is not permitted to retrofit a trailer cou-
pling.
Warning Vehicles with an electric motor generate signif-
icantly less noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users until it is
very close to them, or it may not be heard at all.
This is particularly the case if other road users
have not yet seen your vehicle but are instead
relying on hearing. Drive with particular care,
allowing for the possibility that other road users may behave unpredictably.
The vehicle can be equipped with a sound gen-
erator. The sound generator is activated so that
other road users can hear your vehicle better.
The sound generator is activated at speeds
under 30 km/h and switches off automatically
at higher speeds. Declarations of conformity
Wireless vehicle components The following information applies to all compo-
nents of the vehicle and the information sys-
tems and communication devices integrated

radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant with
the basic requirements and all other relevant
conditions of Directive 1999/5/EC. You can
obtain further information from any Mercedes-
Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehicle
components has been checked and certified
according to the currently valid version of Reg-
ulation ECE-R 10. 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 a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
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 may restrict
the clearance around the pedals or block a

DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. After an accident, immediately
switch the ignition off and remove the key
from the ignition lock. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp
:and
PASSENGER AIR BAG ON indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. Depending on the person in the front-passenger
seat, the front-passenger front airbag must
either be disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper- ative to observe the notes on the "Automatic
front-passenger front airbag deactivation sys- tem" (Y page 42) and on "Children in the
vehicle" (Y page 49).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of
the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto- matic front-passenger front airbag deactiva-
tion system" (Y page 42) and on "Children in
the vehicle" (Y page 49).
R All other persons: the PASSENGER AIR BAG
ON indicator lamp must be lit. The front-
passenger front airbag is enabled. Depending on the build of the person on the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In this case, the front-passenger seat should notbe used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 42) as well as
on "Seat belts" (Y page 35) and "Airbags"
(Y page 39). There you can also find infor-
mation on the correct seat position. Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi-
cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed. Occupant safety
35Safety Z

The seat belt system consists of:
R seat belts
R belt tensioners for the front seat belts and the
outer seat belts in the rear
R belt force limiters for the front seat belts and
the outer seat belts in the rear
If the seat belt is pulled quickly or sharply from
the belt outlet, the inertia reel locks. The belt
strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across
your body. However, it does not pull the vehicle
occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an incorrect seat position or correct the routing of
a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help to
reduce the peak force exerted by the seat belt
on the vehicle occupant.
The belt force limiters on the front seats are
synchronised with the front airbags, which take
on a part of the deceleration force. This can
reduce the forces to which the vehicle occu-
pants are subjected during an accident.
! If the co-driver's seat is not occupied, do not
engage the seat belt tongue in the buckle on
the co-driver's seat. Otherwise, the belt ten-
sioner could be triggered in the event of an
accident and would have to be replaced.
Important safety notes G
WARNING
The seat belt cannot perform its intended pro- tective function if it is not fastened correctly. Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal.
Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak- ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrestis in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtall cannot wear the
seat belts correctly without a suitable, addi-
tional restraint system. The seat belt cannot
perform its intended protective function if it is not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
ries in the event of an accident, sudden brak-
ing or abrupt changes of direction. There is an increased risk of injury, possibly even fatal.
Secure persons less than 1.50 mtall in a suit-
able restraint system.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle: R always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro- priate to the age, weight and size of the child.
R always observe the instructions and safety
notes on the automatic front-passenger front
airbag deactivation system (Y page 42)
R always observe the instructions and safety
notes on "Children in the vehicle" in this Own- er's Manual (Y page 49) in addition to the
child restraint system manufacturer's instal-
lation instructions G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels 36
