PLUG-IN HYBRID operation
Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRID mode, the hybrid
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. The engine is switched on,
even while the vehicle is in motion, when a
higher power output is required. The engine is
usually switched off when the vehicle is station-
ary. Consequently, 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 electric
driving, operation of the electric refrigerant
compressor and to supply 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 252).
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 44).
Important safety notes If the engine is switched off by the ECO start/
stop function, you open the driver's door and
unfasten your seat belt: R
a message appears in the multifunction dis-
play and R
a warning tone sounds
Further information ( Y
page 299).
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 253).
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.
Depending on the vehicle's equipment and
country-specific regulations, the vehicle can be
equipped with Acoustic Vehicle Indication.242

Problems with PLUG-IN HYBRID operation
Internal combustion engine Problem
Possible causes/consequences and P Solutions
You cannot start the
internal combustion
engine. The multifunc-
tion display shows no
display messages. The
READY indicator in the
multifunction display is
off. For example, self-diagnosis is not yet complete or the hybrid drive
system is malfunctioning. X
Switch off the ignition and turn it back on. X
Try to start the internal combustion engine again.
If the internal combustion engine still does not start: X
Consult a qualified specialist workshop.
You wish to pull away,
but the ECO start/stop
function does not start
the internal combustion
engine. The READY indi-
cator in the multifunc-
tion display is off. The ECO start/stop function has failed. The warning and indicator
lamps in the instrument cluster light up. X
Shift the transmission to P .X
Switch off the ignition and turn it back on. X
Start the engine.
The hybrid drive system is faulty. X
Consult a qualified specialist workshop.
Recuperative Brake System Problem
Possible causes/consequences and P Solutions
Braking resistance is
reduced and brake pedal
travel is longer than
usual.
G Risk of accident
The Recuperative Brake System is malfunctioning. X
Observe the additional display messages in the multifunction dis-
play ( Y

Useful information
i This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific 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.
i Read the information on qualified specialist
workshops ( Y
page 29).
Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.
PLUG-IN HYBRID vehicles only:
G WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Pull over as soon as it is safe to do so and
consult a qualified specialist workshop.
All vehicles, except PLUG-IN HYBRID vehi-
cles:
The on-board computer only shows messages or
warnings from certain systems in the multifunc-
tion display. You should therefore make sure
your vehicle is operating safely at all times. For an overview, see the instrument panel illus-
tration ( Y
page 34).
Displays and operation
Instrument cluster lighting The lighting in the instrument cluster, in the dis-
plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
( Y
page 34). X
Turn the brightness control knob clockwise or
counter-clockwise.
If you turn the light switch to X , ` or
X , the brightness is dependent upon the
brightness of the ambient light.
i The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display.
In daylight, the displays in the instrument
cluster are not illuminated.
Speedometer with segments The speedometer is divided into segments only
on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available. R
DISTRONIC PLUS activated ( Y
page 193):
One or two segments in the set speed range
light up. R
DISTRONIC PLUS detects a vehicle in front
that is driving at a slower speed than the
stored speed:
The segments between the speed of the vehi-
cle in front and the stored speed light up.
Tachometer
! Do not drive in the overrevving range, as this
could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.Displays and operation 263
