▷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 74ControlsDriving74
Online Edition for Part no. 01 40 2 956 272 - 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 74, 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 87.
Parking brake
The concept The parking brake is used to prevent the vehi‐
cle from rolling when it is parked.

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

Pull the reel and hold it. The vehicle brakes
hard while the reel is being pulled.
The indicator lamp lights up red, a sig‐
nal sounds and the brake lights light
up.
A Check Control message is displayed.
If the vehicle is slowed down down to a speed of approx. 2 mph/3 km/h the parking brake is
set.
Releasing
With the ignition switched on:
Steptronic transmission: Press the reel
while the brake is pressed or selector
lever position P is set.
The LED and indicator lamp go out.
The parking brake is released.
Automatic release in cars with
Steptronic transmission
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.◀
For automatic release, step on the accelerator
pedal.
The LED and indicator lamp go out.
The parking brake is automatically released
when you step on the accelerator:▷Drive readiness on.▷Drive mode engaged.▷Driver buckled in and doors closed.
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.

Displays of the hybrid
system
Displays in the instrument cluster
The concept The following functions of the hybrid system
are displayed:
▷High-voltage battery charge indicator, refer
to page 86.▷Electric driving: eDRIVE.▷Acceleration boost: eBOOST.▷Energy recovery: CHARGE.▷Auto Start/Stop function and active drive
readiness: READY.
The display depends on the system's operat‐
ing condition.
Note High voltage
Even if no bars are displayed in the bat‐
tery symbol, the high-voltage system is still under high voltage.◀
High-voltage battery charge indicator
When drive readiness is switched on in COM‐
FORT mode, displays the available charge of
the high-voltage battery with bars in a battery
symbol. If five bars are shown, the high-voltage
battery is fully charged.
During normal vehicle operation, the high-volt‐
age battery is charged up to approx. 80 %.
This ensures optimum energy recovery when
braking or driving downhill.
Electric driving: eDRIVE
When driving in COMFORT or ECO PRO
modes, the power output of the electric motor
is indicated by arrows on the instrument clus‐
ter.
Depending on the position of the accelerator
pedal, up to four arrows are displayed simulta‐
neously. The tachometer pointer stays on 0
rpm.
If all four arrows are already displayed, the
combustion engine is switched on, e.g., during
accelerations or on uphill gradients.
