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.

SettingApply parking brake and further secure
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.◀
Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., can‐
not release the parking brake.◀
Pull the reel.
The LED lights up.
The indicator lamp lights up red. The
parking brake is set.
While driving
Use as emergency brake while driving:
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.

If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these reel settings.
Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to reel on the
one-sided roadside parking lights, refer to
page 103.
Low beams Position of switch
with the ignition
switched on: the low beams light up.

▷High beams off/headlight flasher, arrow 2.
The High-beam Assistant can be switched off
when manually adjusting the light. To reacti‐
vate the High-beam Assistant, press the but‐
ton on the turn signal lever.
System limits Personal responsibility
The High-beam Assistant cannot serve
as a substitute for the driver's personal judg‐
ment of when to use the high beams. There‐
fore, manually reel off the high beams in situa‐
tions where required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.

Press button. The green indicator
lamp lights up.
If the automatic headlight control, refer to

When the high beams or headlight flasher are
activated, the front fog lights are not switched
on.

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin to
roll back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
