No lane-correcting brake application occurs if: R
you clearly and actively steer, brake or accel-
erate. R
you cut the corner on a sharp bend. R
you have switched on the turn signal. R
a driving safety system intervenes, e.g. ESP ®
,
PRE-SAFE ®
Brake or Active Blind Spot Assist.R
you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration. R
ESP ®
is switched off.R
the transmission is not in position D .R
a loss of tire pressure or a defective tire has
been detected and displayed. R
an obstacle in the lane in which you are driving
has been detected.
Active Lane Keeping Assist may not detect other
road users or traffic situations. An inappropriate
brake application may be interrupted at any time
if you: R
steer slightly in the opposite direction R
switch on the turn signal R
clearly brake or accelerate
A lane-correcting brake application is interrup-
ted automatically if: R
a driving safety system intervenes, e.g. ESP ®

Press button D .
Indicator lamp C lights up. The Lane Keep‐
ing Assist On message appears in the mul-
tifunction display. If all conditions have been
satisfied, a warning or steering intervention
may be made.
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected, the lines in the assistance graphics display
( Y
page 268) are shown in green. Active Lane
Keeping Assist is ready for use. X
To switch off: press button D .
Indicator lamp C goes out. The Active Lane
Keeping Assist is deactivated. The Lane
Keeping Assist Off message appears in
the multifunction display.
Selecting Standard or Adaptive setting X
In the DriveAssist menu on the on-board
computer, select the Active Lane Keep‐
ing Assist function ( Y
page 271).X
Select Standard or Adaptive .
When Standard is selected, no warning vibra-
tion occurs if: R
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, such as
ABS, BAS or ESP ®
.
When Adaptive
is selected, no warning vibra-
tion occurs if: R
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 neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
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 highway. 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 bendDriving systems 239

PLUG ‑ IN HYBRID operation
Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRID mode, the hybrid
drive system automatically selects the most effi-
cient operating mode for every driving situation.
Drive the vehicle in the usual manner.
To save fuel in HYBRID mode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. The combustion engine is
automatically activated when power output
requirements are high. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine
using the power stored in the high-voltage bat-
tery. In addition, the power is used for partially
electric driving, operation of the electric coolant
compressor and to support the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on PLUG-IN HYBRID
operation ( Y
page 251).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator 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 44). 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 297).
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 cluster
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 252).
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 certain
sound at a speed between 0 and 19 mph
(30 km/h). This helps other road users, partic-
ularly 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 19 mph (30 km/h) the sound is
switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.240

HYBRID operating mode is available.
If you switch from automatic drive program S to
automatic drive program E or E+ , HYBRID oper-
ating mode continues to be selected.
If manual drive program M is deactivated, the
automatic transmission shifts: R
into the automatic drive program that was last
selected R

Each time the engine is started, HYBRID mode
is automatically selected.
Power meter The power meter supports you in electric mode
and displays the output obtained.
If you select the E-MODE operating mode, the
instrument cluster will display the power meter
instead of the tachometer.
