2016 MERCEDES-BENZ C CLASS automatic transmission

drive system automatically selects the most effi-
cient operating mode for every driving situation.
Drive the vehicle in the usual manner.
To save fuel in HYBRID mode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. When power output require-
ments are high, the combustion engine is auto-
matically switched on. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine
using the power stored in the high-voltage bat-
tery. In addition, the power is used for partially
electric driving, operation of the electric coolant
compressor and to support the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on plug-in hybrid oper-
ation ( Y
page 230).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System ( Y
page 45).
Important safety notes If the engine is switched off by the ECO start/
stop function and you open the driver's door: R
a message appears in the multifunction dis-
play and R
a warning tone sounds
Further information ( Y
page 272).
All of the vehicle's systems remain active, if: R
the vehicle is stationary R
the combustion engine is switched off and R
the READY indicator in the instrument cluster
lights up If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
may pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function ( Y
page 231).
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 is the case, for example, when
you are parking and your vehicle is not seen by
other road users.
This requires you to adopt a particularly antici-
patory driving style, as it is necessary to allow
for the possibility that other road users may
behave erratically.
Displays and operation
Electric motor performance display
The power display for the electric motor is loca-
ted on the right-hand side of the instrument
cluster. R
Area C to D (E-DRIVE):
This shows the electric output from the elec-
tric motor, e.g. during electric operation or in
boost mode.
When the motor is switched on, the display is
at limit C . With increasing pressure on the
accelerator pedal the display fills up from C
to D .
Driving with the electric motor: when the
display reaches limit D , the combustion
engine is switched on. If the display is
approaching limit D and you remove your
foot from the accelerator pedal, the display
empties again. The combustion engine is not
switched on. At low speeds, you can therebyPLUG ‑ IN HYBRID operation 225

In automatic drive program S ( Y
page 229) and
during manual gearshifting ( Y
page 229), only
HYBRID operating mode is available.
If you switch from automatic drive program S to
automatic drive program E , HYBRID operating
mode continues to be selected.
If manual drive program M is deactivated, the
automatic transmission shifts: R
into the automatic drive program that was last
selected R
into the driving mode that was last selected
Each time the engine is started, HYBRID mode
is automatically selected.
Operating the on-board computer You can display the current operating condition
of the hybrid drive system in the multifunction
display and on the display of the multimedia
system ( Y
page 227).
In the multimedia system display, you can also
call up a graphic display of the fuel consumption
and generated electricity ( Y
page 228). Menus and submenus

Haptic accelerator pedal
General notes The haptic accelerator pedal helps you to
reduce the fuel consumption and emissions of
your vehicle.
There are two different functions available for
this purpose: R
an additional point of resistance in E-MODE
operating mode ( Y
page 226)R
a double pulse in drive program E
( Y
page 229)
Additional point of resistance in the hap-
tic accelerator pedal
The maximum available electric performance is
indicated by a tangible point of resistance in the
haptic accelerator pedal.
The additional point of resistance is available in
E-MODE operating mode ( Y
page 226).
If you depress the haptic accelerator pedal
beyond the pressure point, the combustion
engine is switched on.
Double pulses in the haptic accelerator
pedal
A tangible double pulse in the haptic accelerator
pedal gives you a recommendation to release
the accelerator pedal. By this means, in
HYBRID , E-MODE or E-SAVE operating mode
the combustion engine can be switched off and disconnected from the power train (overrun
mode).
The double pulse is available in drive program E
( Y
page 229).
After the accelerator pedal has been released,
the coasting cha racteristi cs of the vehicle are
a
dapted to the traffic conditions.
To avoid getting too close to the vehicle in front,
you must apply the brakes manually when nec-
essary.
Driving tips General driving tips Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric driving, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position D and
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion ( Y
page 231).
Additional driving tips ( Y
page 179).
Stationary vehicle If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering gear allows
you to use the power steering without reduced
comfort.
Acceleration
Depending on the operating mode, pulling away
and driving under low load conditions are per-
formed: R
entirely by electric propulsion R
in combination with the internal combustion
engine
When accelerating at an increased or full load,
boost mode is utilized. The electric motor sup-
ports the internal combustion engine by provid-
ing additional torque when the accelerator is
depressed rapidly.230
