! Only use the charging cable to charge the
high-voltage battery. Do not use the charg-
ing cable for other purposes. It may other-
wise be damaged.
The vehicle is supplied with a charging cable
for connection to a mains socket. Only use
the charging cable supplied with the vehicle
or a charging cable approved for the vehicle.
i The charging process can vary depending
on the mains power supply. Therefore,
always observe the local information.
i For short charge times (charging with 16
A), connect the fast-charging cable to the
wallbox or charging station. You can also
use the optionally available charging cable
with the CE plug.
Information about charging from a wallbox
can be found at (Y page 216).
Information about charging at a charging sta-
tion can be found at (Y page 217).
Stowing the charging cable

Setting the maximum charge current G
WARNING
If the charge current draw via a mains socket is too high during the charging process, the
external mains supply may overheat. There is a risk of fire.
Before charging, check the maximum permis-
sible charge current available at the location.
If necessary, contact a qualified specialist
company for assistance.
Adjust your vehicle's settings, if necessary.
! If the charge current is too high, the fuse
could be tripped or the external mains sup-
ply could overheat. Check if the external
mains supply is equipped to handle the pro- grammed charge current. If necessary,
reduce the programmed charge current or
use a different mains socket.
You can set a limit for the values of the charge
current used in charging the high-voltage bat- tery. This acts as a means of preventing the
mains supply from overloading. You can set
this limit by using the controls on the charging
cable or in the on-board computer's menu.
Only set the maximum charge current in the
on-board computer menu if there are no
charge current settings on the charging
cable.
The default value in the vehicle corresponds
to the maximum charge value.
The default value on the charging cable is the
minimum setting. This corresponds to the minimum available charge current from the
mains supply. The value on the charging cable
can be increased and is described below.
i The value of the maximum setting and the
adjustment value may vary depending on
the country.
Before charging the high-voltage battery,
check the maximum permissible charge cur-
rent for the relevant power socket.
X To adjust the setting: press button?
repeatedly until the desired setting is selec- ted in display =.
R Two LEDs are flashing: minimum setting
R All LEDs are flashing: maximum setting
If, after the charging process, the charging
cable is:
R left connected to the power socket, the
currently selected values will be used for
the next charging process.
R removed from the power socket, the values
will be reset to the minimum setting for the next charging process. You may then need
to reset the values of the maximum charge current.
i If the vehicle requires more time than
usual when charging, check the maximum
charge current settings using the controls
on the charging cable or in the on-board
computer's menu.

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.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the
recommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the 222

Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists
you in achieving the most economical driving
style for the selected settings and prevailing
conditions. Consumption can be significantly
influenced by your driving style. :

Range ?is shown under Bonus fr. start Bonus fr. start
and represents the additional range achieved since the beginning of the journey as a resultof an adapted driving style.
If the fuel level has dropped into the reserve
range, theReserve fuel Reserve fuel display message is
shown instead of range ?in the multifunc-
tion display. In addition, the 8warning
lamp in the instrument cluster lights up
(Y page 384). The ECO display consists of three sections,
with an inner and outer area. The sections
correspond to the following three categories: :
Acceleration

acceleration processes):
R the outer area fills up and the
inner area lights up green: mod-
erate acceleration, especially at
higher speeds
R the outer area empties and the
inner area is grey: sporty accel-
eration ;
Coasting
(evaluation of all decel-
eration processes):
R the outer area fills up and the
inner area lights up green: antic-
ipatory driving, keeping your dis- tance and early release of the
accelerator. The vehicle can
coast without use of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the
inner area lights up green: con-
stant speed and avoidance of
unnecessary acceleration and
deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driv-
ing style and light up green as a result of a
particularly economical driving style.
Depending on the driving situation, up to two
areas may light up simultaneously.
At the beginning of the journey, the three
outer areas are empty and fill up as a result of economical driving. A higher level indicates a more economical driving style. If the three

time, the driver has adopted the most eco-
nomical driving style for the selected settings
and prevailing conditions. The ECO display
border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved
range displayed under Bonus fr. start
Bonus fr. start
does not indicate a fixed consumption reduc-
tion.
In addition to driving style, the actual con-
sumption is affected by other factors, such
as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"acceleration" and "smooth driving":
R observe the gearshift recommendation
R drive the vehicle in drive program E
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "con-
stant" will change.
The ECO display summarises the driving style
from the start of the journey to its completion. Therefore, there are more marked changes in
the outer areas at the start of a journey. Dur- ing a prolonged driving time, these changes
are smaller. For more marked changes, per-
form a manual reset (Y page 319).

Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle and
when towing a trailer.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for
a short while. This allows the airflow to cool
the brakes more quickly. 224

Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time, and for staying in
lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
