The electric parking brake is also engaged
automatically if:
R DISTRONIC PLUS brings the vehicle to a
standstill or
R the HOLD function is keeping the vehicle
stationary
R Active Parking Assist is holding the vehicle
at a standstill
In addition, at least one of the following con-
ditions must be fulfilled:
R there is a system malfunction.
R the power supply is insufficient.
R the vehicle is stationary for a lengthy
period.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster
lights up.
The electric parking brake is not automati-
cally engaged if the engine is switched off by the ECO start/stop function.
Releasing automatically The electric parking brake is released auto-
matically when all of the following conditions
are fulfilled:
R the engine is running.
R the transmission is in position Dor R.
R the seat belt has been fastened.
R you depress the accelerator pedal.
If the automatic transmission is in position R,
the trunk lid must be closed.
If your seat belt is not fastened, the following conditions must be fulfilled to automatically
release the electric parking brake:
R the driver's door is closed.
R you have shifted out of transmission posi-
tion Por you have previously driven faster
than 2 mph (3 km/h).
Ensure that you do not depress the acceler-
ator pedal unintentionally. Otherwise the
parking brake will be released and the vehicle
will start to move. Emergency braking The vehicle can also be braked during an
emergency by using the electric parking
brake.
X While driving, push handle :of the electric
parking brake (Y page 222).
The vehicle is braked as long as you keep
handle :of the electric parking brake
pressed. The longer electric parking brake
handle :is depressed, the greater the brak-
ing force.
During braking:
R a warning tone sounds
R the Release parking brake Release parking brake message
appears
R the red F(USA only) or !(Canada
only) indicator lamp in the instrument clus- ter flashes
When the vehicle has been braked to a stand- still, the electric parking brake is engaged. Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging and further damaged
in the event of this occurring again.
X Connect a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than
six weeks, the vehicle may suffer damage as a result of lack of use.
X Visit a qualified specialist workshop and
seek advice.

you switch on the turn signals. In this
event, the warnings are suppressed for a
certain period of time.
R a driving safety system intervenes, e.g.
ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a high-
way.
R the system recognizes solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend. PLUG-IN HYBRID operation
Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRIDmode, the hybrid
system automatically selects the most effi-
cient operating mode for every driving situa-
tion. Drive the vehicle in the usual manner.
To save fuel, in HYBRIDmode, the hybrid
system switches off the combustion engine
as often as possible during the journey when power output requirements are low. When
power output requirements are low, the elec-
tric 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 stationary. Consequently,
there is usually no engine idling as with com-
bustion engine vehicles.
For pulling away and accelerating, the electric motor supports the internal combustion
engine using the power stored in the high-
voltage battery. This energy is also used for
driving in partially electric mode, to operate
the electric refrigerant compressor and sup-
port the 12 V on-board electrical system. In
this way the hybrid drive helps to reduce your
vehicle's fuel consumption.
Observe the driving tips on PLUG-IN HYBRID
operation (Y page 287).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is
initiated. The electric motor is operated as a
generator 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 48). Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
R a message appears in the multifunction dis-
play and
R a warning tone sounds
Further information (Y page 340).
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 clus-
ter 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 288).276
PLUG-IN HYBRID operationDriving and pa
rking

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.
Depending on the vehicle's equipment and
country-specific regulations, the vehicle can
be equipped with Acoustic Vehicle Indication.
Acoustic Vehicle Indication generates a cer-
tain sound at a speed between 0 and 20 mph
(30 km/h). This helps other road users, par-
ticularly pedestrians and cyclists, to hear your vehicle better. The sound can also be heard
inside the vehicle.
The volume depends on the engine speed.
The faster you accelerate, the louder the
sound is. At a speed of over 20 mph
(30 km/h) the sound is switched off. Above
this speed, the natural sounds from the vehi-
cle are sufficient that it can be heard in good time by other road users. PLUG-IN HYBRID operation
