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.
Safety and security9221_ZA; 1; 21, en-USd2ureepe,Version: 2.11.8.12009-05-13T13:56:31+02:00 - Seite 9Z

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.
10Safety and security221_ZA; 1; 21, en-USd2ureepe,Version: 2.11.8.12009-05-13T13:56:31+02:00 - Seite 10

When working on the RBS, certain
precautions must be taken, e.g. when putting
the brake system back into service.
Contact an authorized Mercedes-Benz
Center. Service conducted by qualified
technicians is required particularly for safety-
relevant work and work on safety-relevant
systems such as the RBS.
i For more information on the braking
system and for driving instructions, refer to
the Operator’s Manual.
BAS (Brake Assist System)
If you apply the brakes very quickly, the RBS
provides full brake boost as fast as possible.
In doing so, less brake pedal pressure than
usual is required and the brake pedal travel is
longer.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
i For more information on the BAS, refer to
the Operator’s Manual.
Driving systems
Cruise control/DISTRONIC PLUS*
When the cruise control or the DISTRONIC
PLUS brake the vehicle, the brake pedal is not
depressed.
For information on driving with the
DISTRONIC PLUS, see ( Y page 18).
i For more information on the cruise
control and the DISTRONIC PLUS, refer to
the Operator’s Manual.

Notes
Your vehicle is equipped with a 12-volt
battery and a high-voltage battery. The high-
voltage battery stores the power required for
the electric drive. The electric drive also
starts the combustion engine.
Have any work on the batteries performed at
an authorized Mercedes-Benz Center.
i Read and observe the safety notes
( Y page 9) and the notes on the 12-volt
battery in the Operator’s Manual.26Practical hints221_ZA; 1; 21, en-USd2ureepe,Version: 2.11.8.12009-05-13T13:56:31+02:00 - Seite 26
