the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
The components of the vehicle's high-voltage
electrical system are marked with yellow warn-
ing stickers. The cables of the vehicle's high-
voltage electrical system are orange in color.
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This can happen, for example, when
you are parking and your vehicle is not seen by
other road users. This requires you to adopt a
particularly anticipatory driving style, as it is
necessary to allow for the possibility that other
road users may behave erratically.

High-voltage battery
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
GWARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
!Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery.
Hybrid vehicles: if the vehicle is idle for
lengthy periods, run it for a few minutes once every six weeks to charge up the high-voltage
battery. During the charging process, switch
off all electrical consumers, e.g. the auto-
matic climate control or the seat heating.
PLUG-IN HYBRID vehicles: make sure that
the high-voltage battery is connected to a
charging station during long periods when the
vehicle is standing idle.

GWARNIN G
If th eseat belt is incorrectl yfastened, it can -
no tprotect as intended. Furthermore ,an
incorrectl yfastene dseat belt can caus eaddi-
tional injury, for example, in an accident, dur-
ing braking or when abruptl ychanging direc-
tion .This poses an increased ris kof injury or
eve nfatal injury.
Mak esur ethat all vehicl eoccupant sare

Adjus tth eseat properly before beginning
your journey. Always ensur ethat th ebackrest
is in an almost vertical position and that th e
shoulder section of your seat belt is routed
across th ecenter of your shoulder .
GWARNING
Objects next to th efron tseat that bloc kth e
belt buckle or th emoving belt anchorage on
th efron tseat impair th efunction of th eEmer-
gency Tensioning Devices. The Emergency
Tensioning Devices may no tfunction as inten -
ded and th eseat belt may no longer provide
th eintended protection .This poses an
increased ris kof injury or eve nfatal injury.
Before starting th ejourney, mak esur ethat
there are no objects aroun dth ebelt buckle or
between th efron tseat and door .
GWARNING
Person sunder 5ft (1.50 m) in height canno t
faste nth eseat belt correctl ywithout an addi-
tional suitable restrain tsystem. If th eseat
belt is incorrectl yfastened, it canno tprotect

tene dseat belt can caus eadditional injury, for
example, in an accident, during braking or an
abrup tchang eof direction .This poses an
increased ris kof injury or eve nfatal injury.
Fo rthis reason ,always secure person sunder
5 ft (1.50 m) in height in suitable restrain t
systems .
If achild younger than twelve years old and
under 5ft (1.5 0m) in height is traveling in the
vehicle:
Ralways 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
Ralways observe the instructions and safety
notes on the belt bags for the outer seat belts

Safety
Z

Seat belts may sustain non-visible damage inan accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Ten-
sioning Devices could accidentally trigger or
fail to deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-
shop.
Only use seat belts that have been approved for
your vehicle by Mercedes-Benz.
Proper use of the seat belts
Pay attention to the safety notes about the seat
belt (Ypage 47).
All vehicle occupants must fasten the seat belt
correctly before setting off. Make sure that all
occupants are wearing their seat belts correctly
for the entire journey.
When fastening the seat belt, make sure that:
RThe seat belt tongue is inserted into the belt
buckle that belongs to the seat.
RThe seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
RThe seat belt is not twisted.
Only then can the forces produced in the
event of an accident be evenly distributed
across the belt.
RThe shoulder section of the belt must always
be routed across the center of the shoulder.
The shoulder section of the belt should not
come into contact with your neck and must
not be routed under the arm. Where possible,
adjust the seat belt to the appropriate height.
RThe lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always pass across your hip
joints and never across your stomach or
abdomen. Pregnant women must take partic-
ular care. If necessary, the lap belt can be
pushed down across the hip joints and pulled
tight using the shoulder section.
RThe seat belt is not routed over sharp, pointed
or fragile objects.
If these item s a
re on or in your clothing, e.g.
eyeglasses, pens, keys, etc., stow these items
in a more suitable location.
ROnly one person should use each seat belt at
any one time.
On no account should babies or children
travel sitting on the lap of another vehicle
occupant. During an accident, they could be
crushed between the occupant and seat belt.
RObjects are not secured with a seat belt if the
seat belt is being used by one of the vehicle’s
occupants.
Also make sure that there are no objects, e.g.
cushions, between the occupant and the seat.
Seat belts are solely intended for the protection
and restraint of the vehicle occupants. To
secure objects, luggage or loads, always
observe the "Loading guidelines" (
Ypage 325).
Rear beltbags
iObserve the "Important safety notes" sec-
tion (Ypage 50).
Depending on the vehicle's equipment, the
outer rear seat belts are equipped with a belt
bag. This can be seen from the BELTBAG iden-
tification on the rear seat belt.
GWARNING
In an accident, the belt bag may damage a
non-approved child restraint system. As a
result, the child restraint system may not be
able to provide the intended level of protec-
tion. This poses an increased risk of injury or
even fatal injury.
For this reason, a child restraint system with
an integrated seat belt should always be
installed using LATCH-type (ISOFIX). In a vehi- cle with optional belt bags for the rear seats,
you should only ever use a booster seat with
integrated backrest that has been tested and
approved by Mercedes-Benz in conjunction
with a belt bag. Never use a seat belt equipped
with a belt bag to secure a forward or rear-
ward-facing child restraint system or a boos-
ter seat that has not been approved. For infor-
mation on approved child restraint systems,

(
Ypage 61).
When triggered, belt bags :open, increasing
the protected area of the occupants' ribcages.
The belt bags are triggered depending on the
type and severity of the accident.
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Ypage 47) and the notes on correct use of seat
belts (Ypage 48).

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" (
Ypage 62).
Rear seat belt buckle extenders
The seat belt extender is an integral part of the
PRE-SAFE®convenience function. It is used on
the outer rear seats.
Always ensure that it is possible to move the belt
buckle freely. Always stow objects in the vehicle
correctly.
To assist you in finding the seat belt buckle and
fastening the seat belt:
