Calling up functions in the "My
Mercedes Electric - Vehicle Homepage"
The "My Mercedes Electric - Vehicle Home-
page" allows you access to information about your vehicle and its functions using remote
query and remote configuration. For example,
climate control can be activated using remote
configuration which means that it need not be set in the vehicle. Power for the climate con-
trol is primarily supplied via the charging
cable connected to the mains supply. In this
way, the range of the vehicle in most cases is not reduced. If climate control is activated,
the battery charge level and thus the range
may be reduced. The "Vehicle Homepage"
provides you with information all about how
to use your vehicle.
If the vehicle is entered in your personal area of the "Vehicle Homepage", you can also
access the following functions:
R request the current condition of charge of
the high-voltage battery
R program the departure time (Y page 195)
R order and activate the "Pre-entry climate
control at departure time" function
If the vehicle is charging, the predicted charg-
ing time and the predicted range will also be
shown.
This data is estimated and may be influenced
by the following factors:
R outside temperature
R switched on consumers, e.g. climate con-
trol and seat heating
R personal driving style
R road and traffic conditions
R route characteristics
Therefore, allow for a sufficient reserve.
i Information on additional functions and
operating instructions can be found on the "Vehicle Homepage". Connecting the vehicle to the Internet Via a radio module
This function is not available in all countries
and requires an activated mbrace access.
You can use the "Vehicle Homepage" if the
vehicle has a connection to the Internet via a mobile phone. The radio module uses a
mobile phone connection and transmits the
necessary data by radio. The vehicle auto-
matically recognizes whether a connection tothe Internet via the radio module is possible
or not. No presets are necessary.
To enable the transfer of data via the mobile
communications module, you do not need a
SIM card.
i Restrictions in reception are possible if
the vehicle is in an underground car park,
for example. Restrictions may also occur in areas with poor mobile network coverage. Parking

Important safety notes G
WARNING
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. G
WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicleis stationary.
Observe the legal requirements for the coun- try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save energy Observe the following tips to save energy:
R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not nee-
ded.
R Avoid frequent acceleration or braking. Energy consumption also increases when
driving in low or high outside temperatures, in
stop-start traffic, on short journeys and in
hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs. ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption.
The ECO display consists of three bars:
R Acceleration
Acceleration
R Constant Constant
R Coasting
Coasting
The percent value is the average value of the three bars. The three bars and the mean value
begin at the value of 50%. A higher percent-
age indicates a more economical driving
style. Driving tips
157Driving and pa rking Z

The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
R load
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories:
R Acceleration
Acceleration (evaluation of all accelera-
tion processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant
Constant (assessment of driving behavior
at all times)
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting
Coasting (assessment of all deceleration
processes)
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
To achieve a higher value in the categories
Acceleration Acceleration andConstant
Constant, drive the vehi-
cle in drive program E+orE.
On long journeys at a constant speed, e.g. on
the highway, only the bar for Constant
Constantwill
change.
The ECO display summarizes the driving char- acteristics from the start of the journey to its completion. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer changes. For more dynamic changes, carry out a man-
ual reset.
For further information on the ECO display,
see (Y page 187). Braking
Important safety notes G
WARNING
If you increase the recuperation level on slip- pery road surfaces, the drive wheels may lose
their traction. There is an increased danger of skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec- tive:
R when the condition of charge of the high-
voltage battery increases
R if the high-voltage battery is not yet at a
normal operating temperature
R when driving close to the maximum speed
R when the vehicle is almost stationary
R in transmission position N
R during 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.
Downhill gradients On long, steep gradients, you must reduce the
load on the brakes by selecting maximum
recuperation. This helps you to avoid over-
heating the brakes and wearing them out
excessively.
Recuperation allows the vehicle to be decel-
erated without placing a load on the braking
system. 158
