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

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

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
