Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a high
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or a hole in the road
Ra heavy object strikes the undercarriage or
parts of the chassis
In situations like this, the body, the undercar-
riage, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
Hybrid vehicles have a combustion engine and
an electric motor. The voltage supply for oper-
ating the vehicle electrically is provided by the
vehicle's high-voltage electrical system.
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
30Operating safety
Introduction

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.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle com-
ply with Part 15 of the FCC Rules. Operation is
subject to the two following two conditions: 1)
These devices may not cause harmful interfer-
ence, and 2) These devices must accept any
interference received, including interference
that may cause undesired operation. Changes
or modifications not expressly approved by the
party responsible for compliance could void the
user’s authority to operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the fol-
lowing two conditions: (1) These devices may
not cause interference, and (2) These devices
must accept any interference, including inter-
ference that may cause undesired operation of
the device."
Diagnostics connection
The diagnostics connection is only intended for
the connection of diagnostic equipment at a
qualified specialist workshop.
GWARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle.
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
!If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec-
tion.
Qualified specialist workshop
An authorized Mercedes-Benz Center is a quali-
fied specialist workshop. It has the necessary
specialist knowledge, tools and qualifications to
correctly carry out the work required on your
vehicle. This is especially the case for work rel-
evant to safety.
Observe the notes in the Maintenance Booklet.
Always have the following work carried out at an
authorized Mercedes-Benz Center:
Rwork relevant to safety
Rservice and maintenance work
Rrepair work
Ralterations, installation work and modifica-
tions
Rwork on electronic components
Rwork on the hybrid drive system

Hybrid vehicles
General notes
Hybrid technology combines a fuel efficient
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 356)
RTowing the vehicle with the rear axle raised
(Ypage 355)
RTowing a vehicle with both axles on the
ground (Ypage 356)
Read the safety instructions on towing and tow-
starting (
Ypage 354).
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 changing bulbs 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.
Deactivate the hybrid system manually if:
Rthe 6 restraint system warning lamp in the

danger zone:shift the transmission into posi-
tion N.
XRelease the electric parking brake.
XRoll 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 turn-
ing. 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 transmission to position P.
Depress the electric parking brake
(
Ypage 178).
Secure the vehicle against rolling away
(
Ypage 380).
XTo use the high-voltage switch-off device:
open the hood.
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.

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.
