▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available
when the low beams are turned off.▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
The low beams reel to parking lights after ap‐
prox. 15 minutes of no use.
When the ignition is switched off automatically
by opening or closing the driver's door, un‐
buckling the driver's safety belt or by the auto‐
matic switching of the low beams to parking
lights, the radio-ready state remains active.
Drive readiness
When drive readiness is activated, the vehicle
is operational. Activated drive readiness is the
equivalent of a running engine in conventional
vehicles. Deactivated engine readiness is
equivalent to switching the ignition off.
Drive readiness in detail
The concept
The following are the different drive readiness
variants:
▷Electric drive readiness, Silent Start, refer
to page 76
The vehicle is powered by the electric mo‐
tor.▷Starting the combustion engine, refer to
page 76
The vehicle is powered by the combustion
engine.Hints
Do not leave the vehicle unattended
Do not leave the vehicle unattended with
drive readiness active; otherwise, it may pose a
risk.◀
Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that due to
the lack of engine noise pedestrians and other traffic might pay less attention to the vehicle
due to missing engine noises. Please take spe‐
cial care when parking or leaving a parking
space.◀
Activating drive readiness1.Close the driver's door.2.Depress the brake pedal.3.Press the Start/Stop button.
Drive readiness is activated:
▷Electric drive readiness, Silent Start or▷Starting the combustion engine.
Electric drive readiness, Silent Start The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 78, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀

▷High-voltage battery is heavily discharged
or vehicle electrical system is heavily bur‐
dened.▷High stress of the automatic climate con‐
trol in the heating or cooling phase.▷The engine compartment lid is unlocked.▷The vehicle is being optimized for the cur‐
rent driving style, for instance during the
break-in period or after a service appoint‐
ment.▷The hybrid system is malfunctioning.
Safety mode
An automatically stopped combustion engine
does not start independently when:
▷The driver's door is open and neither the
brake nor accelerator pedal are depressed.▷Unlocked hood.
The indicator lights come on. The combustion
engine can only be started via the Start/Stop
button.
Switching off the vehicle during an automatic engine stop
During an automatic engine stop, the vehicle
can be switched off permanently, e.g., when
leaving it.
1.Press the Start/Stop button.▷The ignition is switched off.▷The radio-ready state is activated.▷The Auto Start/Stop function is deacti‐
vated.▷Transmission position P is engaged
automatically.2.Set the parking brake.
Malfunction
The Auto Start/Stop function no longer
switches of the combustion engine automati‐
cally in the event of a malfunction. A message is displayed. It is possible to continue driving.
Have the system checked.
Electric driving: eDRIVE
Requirements Electric driving is possible:▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is set.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
Possible up to speed of approx. 35 mph, ap‐
prox. 60 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can be driven using electric
power constantly for up to 2-2.5 miles/3-4 km.
CoastingThe combustion engine is automatically stop‐
ped and disengaged from the drive train. This
driving condition is referred to as coasting.
Requirements Coasting is possible:
▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is set.▷The drive system is at operating tempera‐
ture.▷The driver's door is closed.▷In COMFORT mode: when rolling at
speeds exceeding 35 mph, approx.
60 km/h or when braking at speeds above
50 mph, approx. 80 km/h.▷In ECO PRO: mode, when coasting, with‐
out operating the brake, at speeds below
100 mph, approx. 160 km/h.Seite 78ControlsDriving78
Online Edition for Part no. 01 40 2 956 056 - X/14
After the coasting, the combustion or electric
motor restarts depending on the operating
state.
Driving with combustion
engine: DRIVE
The combustion engine provides the primary
performance to move the vehicle. If necessary,
the high-voltage battery is charged at the
same time.
Automatic start while driving The combustion engine is automatically
started under the following conditions while
driving:▷Transmission position M/S is set.▷The speed for electric driving is exceeded
while accelerating.▷The high-voltage battery has an insuffi‐
cient charge.▷High-voltage battery is completely
charged, e.g., when driving downhill.▷During intense accelerations or on inclines.▷System-related requirement for hybrid
components.▷Adapting to the course of the road when
destination guidance is activated.
Automatic parking while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 78, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
performance to move the vehicle.
The electric motor provides assistance as
needed with additional propulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST
Accelerating quickly, such as when passing,
requires the maximum available power from
the electric motor. To do this, apply extra force
to the accelerator pedal.
Energy recovery: CHARGEThe hybrid system makes it possible to con‐
vert kinetic energy into electrical power when
braking and coasting. This recovered energy
charges the high-voltage battery. If necessary,
this stored electrical energy is output to the
electric motor.
The following conditions must be met to re‐
cover kinetic energy:▷The vehicle is moving.▷Transmission position D, M/S is set.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument
cluster, refer to page 92.
Parking brake
The concept The parking brake is used to prevent the vehi‐
cle from rolling when it is parked.

The parking brake is automatically released
when you step on the accelerator:▷Drive readiness on.▷Drive mode engaged.▷Driver buckled in and doors closed.
Inadvertent operation of the accelerator
pedal
Make sure that the accelerator pedal is not op‐
erated unintentionally; otherwise, the vehicle is
set in motion and there is a risk of an acci‐
dent.◀
Automatic Hold
The concept This system assists the driver by automatically
setting and releasing the brake, such as when
moving in stop-and-go traffic.
The vehicle is automatically held in place when
it is stationary.
On inclines, the system prevents the vehicle
from rolling backward when driving off.
