warning stickers. The cables of the vehicle's
high-voltage electrical system are orange.
Vehicles with an electric motor generate sig-
nificantly less noise than vehicles with inter-
nal combustion engines. As a result, in certain situations your vehicle may not be heard by
other road users. This can happen, for exam-
ple, 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 pos-
sibility that other road users may behave
unpredictably. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted into the vehicle which receive and/or
transmit radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant
with the basic requirements and all other rel- evant conditions of Directive 1999/5/E C.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi-fied according to the currently valid version of
Regulation 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
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop
A qualified specialist workshop has the nec-
essary special skills, tools and qualifications
to correctly carry out any necessary work on
your vehicle. This particularly applies to work
relevant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conver-
sions Introduction
27 Z

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.
If components of the restraint system are
activated during an accident, the hybrid sys-
tem is automatically deactivated.
The hybrid system is not activated when the
vehicle is started if:
R a short circuit is detected in the hybrid sys-
tem.
R a hybrid system electrical connection is
disconnected.
This ensures that you do not come into con-
tact with high voltage.
Manual deactivation of the hybrid sys-
tem The hybrid system can be deactivated man-
ually using the high voltage switch-off device.
! To prevent damage to the hybrid system
please observe the following instructions:
R only deactivate the hybrid system man-
ually in the following situations.
R work on the hybrid system may only be
carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
R if the 6 restraint system warning lamp
in the instrument cluster lights up after an
accident.
R if the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated.
R if the vehicle is badly damaged and has to
be towed or transported.
X If possible, move the vehicle out of the
danger zone: shift the automatic transmis-
sion into position N.
X Release the electric parking brake.
X Roll the vehicle to a safe place and park it
safely. Get assistance from others if necessary.
The 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.
X Switch the ignition off.
X Shift the automatic transmission to park
position P.
Apply the electric parking brake
(Y page 213).
Secure the vehicle to prevent it from rolling
away (Y page 443).
X To use the high-voltage switch-off
device: open the bonnet. X
Press release clip :in the direction of the
arrow and pull it out.
X Pull high voltage switch-off device ;apart
until it engages in the stop position.
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. Hybrid vehicles
43Safety Z

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 vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery.
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 automatic
climate control or the seat heating.
Information on charging the high-voltage bat-
tery (Y page 420).
Engine compartment Before opening the bonnet:
X Apply the electric parking brake.
X Shift the automatic transmission to park
position P.
X Switch the ignition off.
X Remove the key from the ignition lock.
or, in vehicles with KEYLESS-GO start-func-
tion or KEYLESS ‑GO
X Remove the Start/Stop button from the
ignition lock.
X Observe the warning notes on the risk of
electric shock (Y page 42).
X Observe the warning notes about the bon-
net (Y page 395). RBS driving safety system (Recupera-
tive Brake System)
RBS supports you when braking with an elec-
tronically-controlled brake boost mode and enables the recovery of kinetic energy (recu-
peration).
For further information on the RBS system
(Y page 273). Panic alarm
X
To activate: press!button :for
approximately one second.
An alarm sounds and the exterior lighting
flashes.
X To deactivate: press!button :

or
X Insert the key into the ignition lock.
or, in vehicles with KEYLESS-GO start-func-
tion or KEYLESS ‑GO
X Press the Start/Stop button.
The key must be in the vehicle.
The panic alarm function is only available in
certain countries. Occupant safety
Introduction to the restraint system
The restraint system reduces 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. 44

Deactivating If you do not intend to use the vehicle for a
longer period of time, you can deactivate KEY- LESS-GO. The key will then use very little
power, thereby conserving battery power. For
the purposes of activation/deactivation, the
vehicle must not be nearby.
X To deactivate: press the&button on
the key twice in rapid succession.
The battery check lamp of the key lights up
twice briefly and KEYLESS-GO is deactiva-
ted.
X To activate: press any button on the key or
insert the key into the ignition lock.
KEYLESS-GO and all of its associated fea-
tures are available again. KEYLESS-GO start function
Bear in mind that the engine can be started by any of the vehicle occupants if there is a key
in the vehicle. Changing the settings of the locking
system
You can change the settings of the locking
system. This means that only the driver's door and the fuel filler flap are unlocked when the
vehicle is unlocked. This is useful if you fre-
quently travel alone.
X To change the setting: press and hold
down the %and& buttons simulta-
neously for about six seconds until the bat- tery indicator lamp flashes twice
