Enviromental protection
Have the high-voltage battery disposed of in
an environment-friendly manner by an
authorized Mercedes-Benz Center.GWarning!
The HYBRID system is energized by high
voltage. The components of the HYBRID
system are indicated by yellow warning
labels. High-voltage cables are orange-
colored.
You could be seriously or even fatally injured
when you
R tamper with components or high-voltage
cables of the HYBRID system
R touch components or high-voltage cables
of the HYBRID system after the vehicle has
been involved in an accident
R touch damaged components of the HYBRID
system
Do not remove the high-voltage battery of the
HYBRID system. Have the high-voltage
battery disposed of in an environment-
friendly manner by an authorized Mercedes-
Benz Center.
i For more information on the high-voltage
battery, see ( Y page 26).
Operating safety
GWarning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired, may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured.GWarning!
Have all work on the vehicle, especially safety-
related work, work on safety-relevant
systems, work on the HYBRID system as well
as maintenance work, carried out by an
authorized Mercedes-Benz Center.
i For more information on operating safety,
refer to the Operator’s Manual.
Vehicle modifications
GWarning!
Improper work on the HYBRID system or
modifications of the vehicle can cause vehicle
systems to cease functioning properly. You
could lose control over the vehicle and cause
an accident.
Therefore, have work on the HYBRID system
and modifications of the vehicle such as
installation or modification of vehicle
equipment carried out by an authorized
Mercedes-Benz Center
i For more information on operating safety,
refer to the Operator’s Manual.
Trailer hitch
! Retrofitting the vehicle with a trailer hitch
is not permissible. Damage caused by
retrofitting the vehicle with a trailer hitch is
not covered by the Mercedes-Benz Limited
Warranty.

Safety notes
Warning labels
GWarning!
Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Danger of electric shock
The components of the HYBRID system are
indicated by yellow warning labels to make
you aware of high voltage. High-voltage
cables are orange-colored.
GWarning!
The HYBRID system is energized by high
voltage.
You could be seriously or even fatally injured
when you
Rtamper with components or high-voltage
cables of the HYBRID system
Rtouch components or high-voltage cables
of the HYBRID system after the vehicle has
been involved in an accident
Rtouch damaged components of the HYBRID
system
Do not remove covers of components of the
HYBRID system that carry the yellow warning
label. Do not tamper with any components or
with the orange high-voltage cables of the
HYBRID system.
Engine compartment
Before opening the hood do the following:
XEngage the electronic parking brake.XShift the automatic transmission into park
position P.
XSwitch off the ignition.
The green or yellow READY indicator lamp
(Y page 16) in the instrument cluster
goes out.
XRemove the SmartKey from the starter
switch or remove the SmartKey with
KEYLESS-GO from the vehicle.
XObserve the safety notes on the danger of
electric shock in this manual.
XObserve the safety notes regarding the
hood in the Operator’s Manual.

Automatic HYBRID system switch-off
The HYBRID system switches off
automatically if
R the Supplemental Restraint System (SRS)
activates the restraint systems in an
accident
R a short circuit in the HYBRID system is
detected
R a plug connection of the HYBRID system is
disconnected
These measures help to prevent you from
coming into contact with high voltage.
High-voltage battery
GWarning!
The high-voltage battery of the HYBRID
system is located in the engine compartment
on the passenger side of the front wall. When
the pressure inside the high-voltage battery
exceeds a certain value, for example in case
of a vehicle fire, inflammable gas will escape
via a duct. The inflammable gas escapes to an
area close to the passenger-side front wheel.
This prevents the high-voltage battery from
exploding.
Stay away from this area of the vehicle.
Driving safety systems
ABS (Antilock Brake System)
Braking
When the ABS engages during braking, the
ABS/ESC warning lamp ÷ in the
instrument cluster ( Y page 14) flashes. The
brake pedal will pulsate only in certain
situations, for example on a slippery road.
i For more information on the ABS, refer to
the Operator's Manual.
RBS (Recuperative Brake System)
The RBS supports you while braking by
electronic controlled brake boost and allows
for regeneration of braking energy. RBS must
be activated when the vehicle is parked each
time before driving off.XMake sure the automatic transmission is in
park position P.XSwitch on the ignition.XApply the brake pedal fully and release it.
The RBS is activated.
While you activate the RBS, less brake pedal
pressure than usual is required and the brake
pedal travel is longer. When you release the
brake pedal, the brake pedal travel is as usual
again.
For more information on the RBS, see
( Y page 12).
GWarning!
If the RBS malfunctions, the yellow RBS
warning lamp é and/or the red brake
warning lamp $ (USA only) or J
(Canada only) in the instrument cluster comes
on. Read and observe the messages in the
multifunction display that may appear. Find
the subentry “Malfunction” of the entry “RBS
(Recuperative Brake System)” in the index of
this manual and follow the steps described in
that section.
GWarning!
If the RBS malfunctions, less brake pedal
pressure than usual may be required and the
brake pedal travel may be longer. The brake
system still functions with full effectiveness.
If required, you have to depress the brake
pedal further. Adapt your speed and driving
accordingly.
GWarning!
Have work on the RBS, e.g. brake pad
replacement, carried out by qualified
technicians only.
