Automatic deactivation of the hybrid
system
The hybrid system is deactivated
automatically if:
R SRS (Supplemental Restrain tSystem)
activates the restraint system in an
accident
R a short circui tis detected in the hybrid
system.
R one of the hybrid system’s electrical
connections is disconnected.
This ensures that you do not come into
contact with high voltage. High-voltage battery
G
WARNING
The high-voltage battery in the hybrid system
is located on the front bulkhead in the engine
compartment on the right-hand side when
viewed in the direction of travel. If, e. g. in the
event of a vehicle fire, the internal pressure of
the high-voltage battery exceeds a certain
value, flammable gas escapes through a line
in the area of the right front wheel. This
prevents the high-voltage battery from
exploding.
Leave the danger area. If necessary, set up
the warning triangle at asuitable distance.
Observe legal requirements. Driving safety systems
ABS (Anti-lock Braking System)
Braking If ABS intervenes when braking, the yellow
÷ ESP®
indicator lamp flashes in the
instrument cluster (Y page 35). You only
feel the brake pedal pulsating in certain
situations, e.g .onslippery roads.
i Further information about ABS; (see
vehicle Operator's Manual). RBS (Recuperative Brake System)
RBS supports you when braking with an
electronically-controlled brake boost mode
and enables the recovery of kinetic energy. G
WARNING
Always have work on the RBS system, e.g.
replacemen tofbrake pads, carried out at a
qualified specialist workshop.
Certain points must be taken into account
when carrying out work on the RBS system,
e.g. for system restart.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop. G
WARNING
If RBS malfunctions, braking resistance may
be reduced and brake pedal travel may be
longer than usual. The brake system is still
fully functional .Ifnecessary, depress the
brake pedal further. Adjust your driving style
and vehicle speed accordingly.
i The first time the brake pedal is
depressed after switching on the engine,
braking resistance may be reduced and
brake pedal travel may be greater than
usual. When you release the brake pedal,
pedal travel then returns to normal.
Remember the following points about RBS
(Y page 20).
The yellow éRBS warning lamp and/or
the red $brake warning lamp light up in
the instrument cluster if RBS is
malfunctioning. Follow the instructions in the
multifunction display (Y page 31).

WARNING
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, for example when
parking or when your vehicle has not been
seen by other road users.
This requires you to adopt aparticularly
anticipatory driving style, as it is necessary to
allow for the possibility that other road users
may behave erratically. Driving

X Start the vehicle.
READY indicator :lights up in the
multifunction display .The vehicle is ready
to drive.
X Depress the brake pedal and select a gear.
i The first time the brake pedal is
depressed, braking resistance is reduced
and brake pedal travel is greater than usual.
Noiseless start
When you start the vehicle, electric operation
mode can be used. The engine starts up when
the power required by the driver exceeds the
power currently available from the electric
motor.
Noiseless start is dependent on the outside
temperature and the operating temperature
of the hybrid system.
If the hybrid system has been started using
noiseless start, green READY indicator :
lights up in the multifunction display.
Pulling away If you are depressing the brake pedal when
shifting the transmission from
Pto Dor Rand
still see the Apply Brake to Shift from 'P' display message in the multifunction

away, see the vehicle Operator's Manual. ECO start/stop function Important safety notes
G
WARNING
When the vehicle is stationary and the green
READY indicator in the instrument cluster is
lit, this means that the engine has been
switched off automatically. All of the vehicle's
systems remain active.
If you remove your foot from the brake pedal
while in transmission position DorR, the
vehicle may pull away automatically.
There is a risk of an accident.
Exit the vehicle only if:
R both the green and yellow READY
indicators in the instrument cluster are off
R you have secured the vehicle to preven tit
from rolling away.
General notes
The ECO start/stop function automatically
switches off the engine at higher speeds
(Y page 23) and whe nthe vehicle comes to
a stop.
The ECO start/stop function is only available
in drive program E.
The system is operational when READY
indicator :turns green in the multifunction
display.
All vehicle systems remain active, e.g. the
automatic climate control.
Automatic engine switch-off
The engine is switched off automatically,
including when:
R the driver releases the accelerator pedal
and does not exceed a speed of 90 km/h
(140 km/h) (Y page 23) or
R the engine has reached its operating
temperature
R the driver’s seat belt is fastened and the
driver’s door is closed
R the driver only slightly depresses the
accelerator pedal
R the hood is closed and engaged properly 22
DrivingDriving and parking

R
During partial electric driving, pulling away
and acceleration, the electric motor
supports the internal combustio nengine.
R During overru nintransmission position D
and braking, the electric motor will operate
as a generator.
i For further information about the ECO
start/stop function (Y page 22) and driving
tips, see the vehicle Operator's Manual. Stationary vehicle
In this operating mode, the internal
combustion engine is primarily switched off.
Electric drive from the refrigerant compressor
ensures that the automatic climate control
system continues to operate. The
electromechanically assisted steering gear
allows you to use the power steering without
reduced comfort. Acceleration/boostf
unction
Depending on the drive progra mand
accelerator pedal position, the vehicle drives
in pure electric mode or in combination with
the engine .The boost function is used when
accelerating or driving at increased or full
load. The electric motor assists the engine by
providing extra torque whenever the
accelerator pedal is depressed quickly. Overrun mode or braking
When decelerating your hybrid vehicle, three
operating conditions are possible:
R energy recovery (Y page 23) takes place
even when the vehicle is decelerating
purely in overrun mode. The electric motor
operates as a generator and stores the
recovered energy in the high-voltage
battery.
R when the brakes are applied lightly, the
vehicle is slowed down further by the
electric motor. This increases the energy recovery taking place. The electric motor
operates as a generator and stores the
recovered energy in the high-voltage
battery.
R during heavy braking, the service brake is
also used to slow down the vehicle. The two
systems work together. Urban driving
The advantages of the hybrid vehicle come
especially clearly into play when driving in the
city. Energy is recovered during the vehicle's
frequent braking.
The vehicle operates exclusively with the
electric motor at speeds of up to
approximately 20 mph (35 km/h), for
example:
R while approaching a traffic light
R in stop-start traffic
i The vehicle operates exclusively with the
electric motor only if all conditions for
automatic engine switch-off are met
(Y page 22). Driving on inter-urban roads
When driving on inter-urban roads, the
vehicle switches between boost phase,
constant phase and energy recovery phase.
Ag reat deal of recovered energy may be
available, depending on the route profile. This
has a positive effect on fuel consumptio nand
emissions. Highway driving
Whe ndriving on a highway, the decrease in
wasted power through recuperatio nhas a
particularly positive effect on fuel
consumption and emissions. 26
