The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(
Ypage 198).
If the drive system is switched on and you turn
the light switch to TorL, the manual
settings take precedence over the daytime
running lamps.
Low-beam headlamps
Even if the light sensor does not detect that it
is dark, the parking lamps and low-beam

Notes on breaking-in a new vehicle
The sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Before driving away, you must ensure
that, for your own safety and to avoid dam-
age, the charging cable has been removed
from the vehicle socket. Otherwise, you
cannot shift the transmission out of posi-
tion P.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
Rwhen the condition of charge of the high-
voltage battery increases
Rif the high-voltage battery is not yet at a
normal operating temperature
Rwhen driving close to the maximum speed
Rwhen the vehicle is almost stationary
130Driving
Driving and parking

The various different levels are to be used
under the following conditions:
D+Driving without much braking
and without the presence of
obstacles or sharp bends
The vehicle retains the maxi-
mum possible amount of kinetic
energy.
DNormal driving
D-Sporty driving or driving on a
downhill gradient
The brake pedal does not need
to be used as often because the
extent of the deceleration is
greater than inD.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal.
DAUTO
(radar-
based)
The intensity of recuperation is
automatically adjusted to the
current traffic situation.
Default setting
In levels Dand D-, deceleration can be con-
trolled in an infinitely variable manner using
the accelerator pedal.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
Rwhen the condition of charge of the high-
voltage battery increases
Rif the high-voltage battery is not yet at a
normal operating temperature
Rwhen driving close to the maximum design
speed
Rwhen the vehicle is almost stationary
Rin transmission position N
Rduring and after ESP stability control
If you do not make an additional effort to
apply the brake yourself, the braking effect may not be sufficient. If necessary, counter-
act the reduced regenerative braking effect
by applying the brake yourself.
Radar-based recuperation
The vehicle uses the sensors of COLLISION
PREVENTION ASSIST PLUS during radar-
based recuperation (D
AUTO). The sensors
detect the distance to the vehicle ahead and
its speed. The intensity of recuperation is
then automatically adjusted to the current
traffic situation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely var-
iable from overrun mode (no recuperation) to
maximum recuperation.
Maintain sufficient distance to the vehicle in
front. Mercedes-Benz recommends that you
activate COLLISION PREVENTION ASSIST
PLUS as a visual and acoustic aid.
Examples of radar-based recuperation:
RApproaching a slower vehicle, a decelerat-
ing vehicle or when following a vehicle
downhill. Your vehicle decelerates slightly
and increases recuperation.
RDriving when no vehicle is detected in front
or when a vehicle is detected in the far dis- tance or an accelerating vehicle is detec-
ted. Your vehicle switches to overrun mode
at higher speeds.
RDriving on a steep downhill slope. Acceler-
ation downhill is reduced and recuperation
is increased. This is comparable with shift-
ing down when driving downhill.
XTo activate radar-based recuperation:
pull steering wheel paddle shifter :or;
towards you and hold for about one second.
XTo deactivate radar-based recupera-
tion: briefly pull steering wheel paddle
shifter :or; towards you.
Transmission139
Driving and parking
Z

If you change between radar-based and man-
ual recuperation, the following levels are acti-
vated depending on the selection via the
steering wheel paddle shifters:
:Steering
wheel paddle
shifter -selects D-(maximum
recuperation)
; Steering
wheel paddle
shifter +selects D+(overrun)
In particular, the function of the radar sensors
can be impaired in the case of:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper-
ation checked at a qualified specialist work-
shop immediately. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
If the radar sensors are not available, the sys-
tem switches automatically to level Dwith
moderate recuperation. Have the radar sen-
sors checked at a qualified specialist work-
shop immediately.
Automatic adjustment of recuperation
on downhill gradients
The vehicle can detect steep downhill gradi-
ents. To reduce acceleration downhill and to
charge the high-voltage battery, recuperation
is increased steplessly. This is comparable to
the engine brake in a combustion engine
when you downshift a gear on a downhill gra-
dient. Automatic adjustment of recuperation on
downhill gradients is available in level
D
AUTO
or on vehicles without steering wheel paddle
shifters in levelD.
Intelligent recuperation
The vehicle uses the map and camera data of
Traffic Sign Assist in addition to the sensors
of COLLISION PREVENTION ASSIST PLUS
during radar-based recuperation (D
AUTO). The
rate of recuperation is then automatically
adjusted to the current traffic situation, tak-
ing the current and future maximum speed
into account.
High-voltage battery
Important safety notes
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
140High-voltage battery
Driving and parking

The electric parking brake secures the vehicle
automatically if the HOLD function is activa-
ted and:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto- matically switched off by the ECO start/
stop function.
Ra system malfunction occurs.
Rthe power supply is not sufficient.
The Brake Immediately
message may also
appear in the multifunction display.
XImmediately depress the brake firmly until
the warning message in the multifunction
display goes out.
The HOLD function is deactivated. The horn
sounds at regular intervals if you have
switched off the engine, released the seat
belt and opened the driver's door with the
HOLD function activated. The sounding of the
horn alerts you to the fact that the HOLD
function is still activated. If you attempt to
lock the vehicle, the tone becomes louder.
The vehicle cannot be locked until you have
deactivated the HOLD function.
iAfter switching off the engine, it can only
be started again once you have deactivated
the HOLD function.
PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. When maneuvering, parking or pulling out of a parking space, make sure that
there are no persons, animals or objects in
the area in which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rshift the transmission to position D,Ror N
Rrelease the electric parking brake
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.
