internal combustion engine with a powerful
electric motor.
Important safety notes
Danger of electric shock
GDANGER
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.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle'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:
RTransporting the vehicle (Ypage 381)
RTowing a vehicle with both axles on the
ground (Ypage 380)
Read the safety instructions on towing and tow-
starting (
Ypage 379).
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 color.
The ignition must be switched off when carrying
out general tasks, such as adding washer fluid to
the windshield washer system or checking the
coolant level.
Automatic switching 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:
Ran electrical short circuit is detected in the
hybrid drive system
Ran electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching 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:
Ronly deactivate the hybrid drive system
manually in the following situations.
Rwork on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
42Hybrid vehicles
Safety

Deactivate the hybrid system manually if:
Rthe6 restraint system warning lamp in the
instrument cluster lights up after an accident
Rthe vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
Rthe vehicle is badly damaged and has to be
towed or transported
XIf possible, move the vehicle out of the
danger zone: shift the automatic transmis-
sion into position N.
XRelease the electric parking brake.
XRoll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
iThe vehicle is locked automatically when
the ignition is switched on and the wheels are
turning. There is therefore a risk of being
locked out if the vehicle is being pushed or
tested on a dynamometer.
XSwitch the ignition off.
XShift the automatic transmission to park posi-
tion P(Ypage 170).
Depress the electric parking brake
(
Ypage 190).
Secure the vehicle against rolling away
(
Ypage 406).
XTo use the high-voltage switch-off device:
open the trunk lid.
XLift the trunk floor upwards (Ypage 329).
XRemove the right-hand paneling in the trunk.
XPress release clip :in the direction of the
arrow and pull it out.
XPull the high voltage switch-off device ;
apart until it engages in the stop position.
If the hybrid drive system has been deactivated
due to reasons mentioned above, have it checked at a qualified specialist workshop
before reactivation.
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.

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:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds with the
engine running
Rlights up again while the engine is running

GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.

GDANGER
If the restraint system is malfunctioning, indi- vidual restraint system components may be
triggered unintentionally or might not be trig-
gered at all in the event of an accident with a
high rate of vehicle deceleration. This could
affect Emergency Tensioning Devices or air
bags, for example. The vehicle's high-voltage
electrical system may also not be deactivated
as intended in the event of an accident. You
could suffer an electric shock if you touch the
damaged components of the vehicle's high-
voltage electrical system. This poses an

PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 53) and on "Chil-
dren in the vehicle" (Ypage 61). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 53). Be sure to
observe the notes on "Seat
belts“ (
Ypage 46) and "Air bags"
(Ypage 50). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat belts
and the outer seat belts in the rear
RBelt bags for the outer seat belts in the rear,
depending on the vehicle's equipment
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor- rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants during an accident.
!If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of
the front-passenger seat. This may otherwise
lead to the triggering of the Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.

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
in the rear (

GWARNING
The seat belts may not perform their intended protective function if:
Rthey are damaged, modified, extremely
dirty, bleach or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-

Occupant safety47
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,
