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.

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.

the Operator’s Manual.
Driving
Driving tips
R Think ahead and keep sufficient distance.
R Avoid frequent and rapid acceleration as
well as abrupt braking.
R In semi-electric operation, when driving off
and when accelerating, the electric drive
supports the combustion engine.
R The electric drive functions as a generator
when coasting the vehicle with the
automatic transmission in drive position D
and during braking.
i For more information on the ECO Start/
Stop function, see ( Y page 17). For
additional general driving instructions,
refer to the Operator’s Manual.
Driving with activated DISTRONIC
PLUS
When the DISTRONIC PLUS recognizes that
the preceding vehicle stops, it will brake your
vehicle to a complete stop. The combustion
engine is turned off automatically only after
both vehicles have come to a complete stop.
The green READY indicator lamp in the
instrument cluster continues to be
illuminated.
i For more information on the ECO Start/
Stop function, see ( Y page 17). For
additional information on the DISTRONIC
PLUS, refer to the Operator’s Manual.
Parking
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!
When the green READY indicator lamp in the
instrument cluster is on while the combustion
engine is off, the combustion engine has been
turned off automatically. All vehicle systems
continue to be active. When you open the
driver’s door, unbuckle the seat belt, or take
your foot off of the brake pedal, the
combustion engine starts automatically. The
vehicle could start to drive off. An accident
causing serious or even fatal personal injury
to you and/or others could be the result.
Therefore, always do the following before
leaving the vehicle:
R Engage the electronic parking brake.
R Shift the automatic transmission into park
position P.
R Switch off the ignition. The green or yellow
READY indicator lamp goes out.

combustion engine was turned off
automatically. Air recirculation switches on
automatically. The indicator lamp in rocker
switch g is not lit when the air
recirculation mode is switched on
automatically.
Air conditioning switched on
automatically
If the operating temperature of the high-
voltage battery is too high, it will be cooled by
the climate control system. The air
conditioning switches on automatically.
In such circumstances it is not possible to
switch off the air conditioning via COMAND
for several minutes.
i For more information on the climate
control system, refer to the Operator’s

GWarning!
The electrolyte, i.e. the battery fluid, is toxic
and caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected
area with water and seek medical help
immediately.
For information on the location of the 12-volt
battery and the high-voltage battery, see
(Y page 13).
! Deep discharge caused by prolonged
periods of the vehicle not being used, can
damage the high-voltage battery.
During such periods, operate the vehicle
every 4 weeks for several minutes in order
to charge the high-voltage battery.
During the charging process, switch off
electrical consumers that are currently not
needed, e.g. climate control system or seat
heating.
If necessary, get a jump start.
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.
If you do not intend to operate your vehicle
for an extended period of time, contact an
