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

R
the high-voltage battery is charged
sufficiently
R there are no malfunctions in the hybrid
system
i Yellow READY indicator :may still
appear in the multifunctio ndisplay, even if
all conditions for automatic engine switch-
off are met. Continue to maintain a speed
above 15 mph (20 km/h) until READY
indicator :turns green in the
multifunction display.
If all the conditions for automatic engine
switch-off have not been fulfilled, yellow
READY indicator :lights up. The internal
combustio nengine will not be switched off
automatically, if:
R the self-diagnosis functio nofthe engine
control unit is still active
R the temperature of the coolant or catalytic
converter is too low
R there is a malfunction in the hybrid system
R the climate control of the vehicle requires
it
R the high-voltage battery is being charged
(Y page 29)
R the vehicle has rolled back shortly
beforehand
R automatic emissions tests are running
Automatic engine start
The automatically switched-off internal
combustion engine starts automatically in
certain situations, if:
R you demand more power than the electric
motor can provide by depressing the
accelerator pedal
R the condition of charge of the high-voltage
battery has reached the lower limit
R the settings of the automatic climate
control require it, e.g. at high outside
temperatures above 86‡ (30 †) Overrun mode
The engine is switched off and disconnected
from the drive train. The electric motor
operates as a generator to produce the power
required for the auxiliary consumers and
charges the high-voltage battery.
Overrun mode is available in the speed range
below 90 mph (140 km/h).
Extended overrun mode
Overrun mode allows you to increase the
vehicle range.
When the vehicle is in overrun mode:
X
Pull the right-hand steering wheel paddle
shifter.
Recuperation is reduced so that only the
power supply for the auxiliary consumers
currently operating is covered. The high-
voltage battery is not being charged.
You can tell that recuperation is no longer
operating at full capacity by looking at the
power display for the electric motor
(Y page 28).
In this operating mode, the vehicle
decelerates less rapidly than a conventional
vehicle.
This function is deactivated again if:
R the engine starts up
R you depress the brake pedal
R you pull the left-hand steering wheel paddle
shifter Driving
23Driving and parking Z

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

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Electric motor performance display
The electric moto
rpower display in the
instrument cluster shows:
R how much of the maximum available
electric motor output is currently being
used
R how much electrical energy is being
delivered through recuperation Upper area
:shows the output obtained
from the electric motor, e.g. when driving
using the electric motor or with the boost
function. During electric drive, the engine
starts up when the display reaches the "MAX"
mark at the top. This allows you to control
how much the electric drive is used at low
speeds.
Lower area ;shows the recuperated output
which is stored in the high-voltage battery as
electrical energy. When the indicator reaches
the mark at the bottom, this means that the
recuperative braking power has been fully
utilized. The service brake is activated. Operating the on-board computer
i For information about operating the on-
board computer and COMAND, see the
