Aut oma tic engine startThe automatically switched-off internal combus -
tio n engin e start s automatically in certai n situa-
tions , if:R
th e power demand from th e driver via th e
accelerato r pedal is greate r than th e electric
motor alon e can provideR

Over ru n mod eIn overrun mode, th e combustio n engin e is
switched off and is disconnected from th e driv e
train. The electric motor: R
generates low thrust , whic h correspond s to
th e overrun mod e of an active combustio n
engin eR
function s as a generator and produce s th e
necessary energ y for th e auxiliary consumer s
and charge s th e high-voltage battery
Ove rrun mod e is possible in th e followin g spee d
range: R
in driv e program E below 81 mph (13 0 km/h)R
in driv e program E+ below 11 2 mph
(18 0 km/h)
In driv e program E+ , after th e accelerato r pedal
has been released th e coasting characteristic s
of th e vehicl e are adapted to th e traffic condi-
tions . Further information about th e haptic
accelerato r p edal ( Y

Route-based operating strategy Fo r th e route-based operating strategy, th e sys-
te m factors in information about th e expecte d
rout e when rout e guidance is active.
The information on th e rout e is provide d by th e
multimedia system and includes th e following:R
road categories R
spee d limitation sR
dat a on downhill gradients The use of electric energ y is automatically opti-
mally distributed from th e beginnin g to th e en d
of th e journey, usin g information about th e
route. The distribution is pre-emptive and takes
int o consideration : R
th e sections of th e journey aheadR
th e energ y consumption on th e whole rout e
The condition of charge of th e high-voltage bat -
tery is thus systematically controlled. In addi-
tion, th e control function takes int o accoun t
that: R
th e fuel saving s throug h th e use of electrical
energ y can vary, depending on th e rout e (e.g.
urban , interurban or highway) R
th e use of electrical energ y is held available in
particular for electric operation (e.g. urban
routes)
The vehicl e thus automatically select s th e opti-
mum driving mod e for th e respectiv e sectio n of
th e route.
The route-based operating strategy is available
under th e followin g conditions: R
driv e program E+ is selected R
HYBRID driving mod e is selectedR
active rout e g uidance is activated R
suitable map dat a is available
When th e route-based operating strategy is
bein g used, th e area in fron t of th e vehicl e is
shown as green in th e multifunction display.

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
page 277). X
Observe the information regarding indicator and warning lamps in

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 28).
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:
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.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do so.
Contact a qualified specialist workshop.
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 33).
Displays and operation
Instrument cluster lighting The light sensor in the instrument cluster auto-
matically controls the brightness of the multi-
function display. In daylight, the displays in the
instrument cluster are illuminated. A dimming
function is not possible in daylight.
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 is located between the
instrument cluster and the multimedia system
display ( Y
page 35). X
Turn the brightness control knob clockwise or
counter-clockwise.
If you turn the light switch ( Y
page 130) to the
` , X or X position, the brightness
will depend upon the brightness of the ambi-
ent light.
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.
PLUG-IN HYBRID vehicles: if you select the oper-
ating mode E-MODE , the display in the instru-
ment cluster changes from tachometer to power
meter ( Y
page 242).256

Head-up display
General notes The head-up display projects information from
the navigation system and the driver assistance
system above the dashboard into the driver's
field of vision. The head-up display allows the
driver to see all of the information without hav-
ing to take their eyes off the road.
A requirement for the display of the contents is
that the following functions are available in the
vehicle and are switched on: R
Cruise control R
DISTRONIC PLUS R
Traffic Sign Assist R
Navigation
Important safety notes The head-up display is only an aid and is not a
substitute for attentive driving.
Speed limits and overtaking restrictions are not
always correctly displayed. Traffic signs always
have priority over the Traffic Sign Assist display.
The visibility of the head-up display is influenced
by the following conditions: R
the driver's seat position R
the positioning of the display image R
the general ambient light R
sunglasses with polarization filters R
wet roads R
blocking of sunlight by objects on the display
cover
In the event of extreme sunlight, sections of the
display may fade. This can be reversed by
switching the head-up display off and on again.
i Vehicles with the head-up display are equip-
ped with a special windshield. Should repairs
be necessary, have the windshield replaced at
a qualified specialist workshop. Displays and operation Switching the head-up display on/off X
