In automatic drive programS(Ypage 250) and
in manual drive program M(Ypage 250), only
HYBRID operating mode is available.
If you switch from automatic drive program Sto
automatic drive program Eor E+ ,HYBRID oper-
ating mode continues to be selected.
If manual drive program Mis deactivated, the
automatic transmission shifts:
Rinto the automatic drive program that was last
selected
Rinto the driving mode that was last selected
Each time the engine is started, HYBRIDmode
is automatically selected.
Power meter
The power meter supports you in electric mode
and displays the output obtained.
If you select the E-MODEoperating mode, the
instrument cluster will display the power meter
instead of the tachometer.
iThe tachometer appears again if:
Ryou select HYBRID,E-SAVE orCHARGE
Rthe current state of charge of the high-volt-
age battery is too low to drive the vehicle in
the E-MODE electrical operating mode
The power meter is divided into the following
areas:
RLimit:(OFF):
If the needle reaches limit :, the electric
motor and the combustion engine are
switched off.
RArea ;to? (CHARGE):
This shows the recuperated energy which is
stored in the high-voltage battery as electrical energy.
The more recuperated energy the high-volt-
age battery has, the further needle ?travels
in direction =. When the needle reaches limit
=, the maximum amount of recuperative
braking power has been reached.
In addition to the recuperative braking power,
the mechanical brakes are activated in the
area between ;and =.
ROutput range of electric motor: ?toA:
The electric output of the electric motor is
displayed here. When the power meter needle
reaches position ?, the electric motor is
operational. With increasing pressure on the
accelerator pedal, the needle moves towards
A.
The output limit of the electric motor Acan
be felt via the additional pressure point in the
haptic accelerator pedal.
If you do not press the haptic accelerator
pedal beyond the pressure point, you can
control electric operation, at low speeds, to
only drive in electric mode.
ROutput range of combustion engine: AtoB:
The output of the combustion engine and the
electric motor is displayed here. When the
power meter needle reaches position Aand
you press the haptic ac

celerator pedal
beyond the pressure point, then the combus-
tion engine is switched on.

In addition to automatic drive programs Eand S,
you can switch to manual drive program Musing

In manual drive program M, you can briefly
change gear yourself by using the steering

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:
Ran additional point of resistance in E-MODE
operating mode (Ypage 243)
Ra double impulse in E+operating mode
(Ypage 250)
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 (
Ypage 243).
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. The combustion engine
can switch off and be disconnected from the
drive train (overrun mode).
The double pulse is available in drive program E+
(
Ypage 250). After the accelerator pedal has been released,
the coasting characteristics of the vehicle are
adapted to the traffic conditions.
To
avo
id 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 Dand
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion (
Ypage 252).
Additional driving tips (
Ypage 192).
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:
Rentirely by electric propulsion
Rin 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.
Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 240). The electric motor operates as
PLUG‑IN HYBRID operation251
Driving an d parking
Z

a generator and stores the recovered energy
in the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place (
Ypage 240). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery
Rwhen the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together
Urban driving
Energy is recuperated during frequent deceler-
ation and stopping in city traffic.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 81 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (
Ypage 252).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Rconstant energy consumption
Renergy recuperation
Relectric operation mode
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in particular
by reduced power losses.
The internal combustion engine will be switched
off automatically, if:
Rthe driver removes his or her foot from the
accelerator pedal in drive program Eand a
speed of 81 mph (130 km/h) is not exceeded
Rthe driver removes his or her foot from the
accelerator pedal in drive program E+and a
speed of 112 mph (180 km/h) is not excee-
ded
Further information on the automatic engine
switch-off (
Ypage 252).
ECO start/stop function
General notes
The ECO start/stop function switches the inter- nal combustion engine off automatically when
the vehicle stops moving and at high speeds
(
Ypage 253).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs Eand E+. Electric-only operation
is only possible in drive programs Eand E+.
Additional information for drive programs Eand
E+ (
Ypage 250).
Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his or her foot from the
accelerator pedal in drive program Eand a

(
Ypage 253)
Rthe driver removes his or her foot from the
accelerator pedal in drive program E+and a
speed of 112 mph (180 km/h) is not excee-

Rthe engine has reached its operating temper- ature
Rthe driver’s seat belt is fastened and the
driver’s door is closed
Rthe driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
Rthe self-diagnosis function of the engine con-
trol unit is still active
Rthere is a malfunction in the hybrid drive sys-
tem
