General notes
Hybrid technology combines a fuel-efficient
internal combustion engine with a powerful
electric motor. Important safety notes
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be sure
to observe the following sections:
R Transporting the vehicle (Y page 401)
R Towing the vehicle with both axles on the
ground (Y page 401)
Read the safety instructions on towing and tow- starting (Y page 399). All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in colour.
The ignition must be switched off when carrying out general work, such as replacing bulbs or
checking the coolant level.
Automatic switch-off of the hybrid drive system If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
R an electrical short circuit is detected in the
hybrid drive system
R an electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact with high voltage.
Manual switch-off of the hybrid drive
system The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
! To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions:
R only deactivate the hybrid drive system
manually in the following situations.
R work on the hybrid drive system may only
be carried out at a qualified specialist work- shop, even when it has been deactivated
manually. Hybrid vehicles

due to reasons mentioned above, have it
checked at a qualified specialist workshop
before reactivation.
High-voltage battery G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceeda critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
WARNING
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 the 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. If the vehicle is idle
for lengthy periods leave the high-voltage bat- tery connected to a charging station.

Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 46)
R adjust their seat and head restraint properly
(Y page 108).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 107).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 48).
An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit- uation are deployed. However, seat belts and
airbags generally do not protect against objects penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (Y page 55).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 58). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering Occupant safety

unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system to
accommodate a person with disabilities, con-
tact a Mercedes-Benz Service Centre. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running
All vehicles, except hybrid vehicles: G
WARNING
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. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.

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 ON indicator lamp
:and
PASSENGER AIR BAG OFF 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. 44
Occupant safetySafety

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 51) and on "Children in the
vehicle" (Y page 58).
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 51) and on "Children in
the vehicle" (Y page 58).
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 51) as well as
on "Seat belts" (Y page 45) and "Airbags"
(Y page 48). 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. 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
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.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted by
the seat belt on the vehicle occupant is reduced.
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 Occupant safety
45Safety
Z

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 51)
R always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 58) in addition to the child restraint
system manufacturer's installation and oper-
ating 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 Seat belts may sustain non-visible damage in
an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts can tear or fail, for example in the event of an accident. Modified
seat belt tensioners may be deployed unin-
tentionally or fail to be deployed when
required. There is an increased risk of injury,
possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have
the seat belts checked immediately at a quali- fied specialist workshop.
Mercedes-Benz recommends that you only use
seat belts which have been approved specifi-
cally for your vehicle by Mercedes-Benz. Other- wise, your vehicle's general operating permit
could be invalidated.
Correct seat belt use Pay attention to the safety notes about the seat
belt (Y page 45).
All vehicle occupants must fasten their seat
belts correctly before you start driving. You
must also make sure that all vehicle occupants
have fastened their seat belts correctly during
the journey.
When fastening your seat belt, always make
sure that:
R the seat belt tongue is inserted into the belt
buckle that belongs to the seat.
R the seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can the forces which occur be dis-
tributed over the area of the belt.
R the shoulder section of the belt is routed
across the centre of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be routed
under your arm. Where possible, adjust the
seat belt to the appropriate height.
R The lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always be routed across
your hip joints and not across your abdomen. 46
Occupant safetySafety

Pregnant women must take particular care
with this. If necessary, push the lap belt down
to your hip joint and pull it tight using the
shoulder section of the belt.
R The seat belt is not routed over sharp, pointed
or fragile objects.
If such objects are located on or in your cloth-
ing, e.g. pens, keys, spectacles, etc. stow
these in a suitable location.
R Only one person should use each seat belt at
any one time.
Babies and children must never travel sitting
on the lap of another vehicle occupant. In the event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R Do not secure any objects with a seat belt if
the seat belt is being used by one of the vehi-
cle's occupants.
Also ensure that no objects are placed
between a person and the seat. e.g. a cush-
ion.
Seat belts are solely intended to secure and
restrain persons. To secure objects, luggage or
loads, always observe the "Loading guidelines"
(Y page 351).
Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y page 45) and the information on the correct
use of the seat belt (Y page 46).Basic illustration X
