Starting the combustion engineEnclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times in quick succession. Otherwise, the fuel
is not burned or is inadequately burned, posing
a risk of overheating and damage to the cata‐
lytic converter.◀
The combustion engine is started with Acti‐
vate drive, refer to page 71, readiness under
the following conditions:▷The drive system is not at operating tem‐
perature.▷The temperature of the hybrid system is
too high.▷The high-voltage battery has an insuffi‐
cient charge.
Driving away
1.Activate drive readiness.2.Select transmission position D, M/S or R.3.Release the parking brake.4.Drive away.Deactivating drive readiness
After stopping the vehicle:1.Select transmission position P.2.Press the Start/Stop button.3.Set the parking brake.
After parking the vehicle, you may hear noises
due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
Before driving into a car wash In order for the vehicle to be able to roll into a
car wash, pay attention to the information re‐
garding Washing in automatic car washes, re‐
fer to page 227.
Automatic Engine Start/Stop
Function
The concept The automatic engine start-stop function
helps save fuel. The system switches off the
combustion engine when conditions for elec‐
tric driving, refer to page 73, have been met.
The ignition or drive readiness remains
switched on.
The tachometer registers 0 rpm. If necessary,
the combustion engine starts automatically.
The combustion engine is also stopped during
the trip when coasting or braking. This driving
condition, in which the vehicle is traveling with‐
out power and energy recovery is not active, is
referred to as coasting, refer to page 73.
Note The combustion engine is not switched off au‐tomatically in the following situations:
▷The combustion engine is not at operating
temperature.▷High voltage battery is heavily discharged
or vehicle electrical system is heavily bur‐
dened.Seite 72ControlsDriving72
Online Edition for Part no. 01 40 2 909 774 - VI/13
▷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
breaking-in period or after a service ap‐
pointment.▷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 lamps 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 engaged.▷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 engaged.▷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 73DrivingControls73
Online Edition for Part no. 01 40 2 909 774 - VI/13
After the coasting, the combustion or electric
motor restarts depending on the operating
state.
Driving with the combustion
engine: DRIVE
The combustion engine provides the primary
drive power 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 engaged.▷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 73, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
drive power 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 engaged.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument
cluster, refer to page 98.
Parking brake
The concept The parking brake is used to prevent the vehi‐
cle from rolling when it is parked.

Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, for example, by turning the steering
wheel in the direction of the curb. ◀

For automatic release, operate the accelerator
pedal.
The LED and indicator lamp go out.
Subject to the following requirements, the
parking brake is automatically released by op‐
eration of the accelerator pedal:▷Drive readiness on.▷Drive position 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.◀
Manual release The parking brake can be released manually in
the event of a power failure or electrical fault.
Before releasing, secure the vehicle
against rolling
Before releasing the parking brake manually,
and whenever you park the vehicle with the
parking brake released, ensure that position P
of the automatic transmission is engaged.
Secure the vehicle in a manner appropriate to
the inclination of the road, e.g., with a wheel
chock; otherwise, there is the danger of the ve‐
hicle rolling.◀

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 away.
For your safety
Under the following conditions, Automatic
Hold is automatically deactivated and the park‐
ing brake is set:
▷The engine is switched off.▷A door is opened and driver's safety belt is
unbuckled while the vehicle is stationary.▷The moving vehicle is brought to a stand‐
still using the parking brake.
The indicator lamp switches from
green to red and the letters AUTO H go out.
