charge current. If necessary, lower the set
charge current or use another power
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
power 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 standard value is the minimum
charge current setting. This corresponds to
the minimum available charge current from
the power supply.
iThe value of the maximum setting and the
relevant adjustment values may vary
depending on the country.
Before charging the high-voltage battery,
have the maximum permissible charge cur-
rent for the relevant power socket checked by
an electrician.
XTo adjust the setting: press button?
repeatedly until the desired setting is selec-
ted in display =.
RTwo LEDs are flashing: minimum setting
RAll LEDs are flashing: maximum setting
Information about the charging time
(
Ypage 338)
If, after the charging process, the charging
cable is:
Rleft connected to the power socket, the
currently selected values will be used for
the next charging process.
Rremoved 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.
If the charge current values that have been
set on the charging cable and the on-board computer are different, the high-voltage bat-
tery is charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:
Rthe settings of the maximum charge cur-
rent on the controls of the charging cable
Rthe settings of the maximum charge cur-
rent in the menu of the on-board computer

Driving and parking

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.:
Rload
RTire pressure
Rcold start
Rchoice of route
Relectrical 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:
RAcceleration(evaluation of all accelera-
tion processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(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
RCoasting(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
and 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
will
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 (
Ypage 187).
Braking
Important safety notes
GWARNING
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:
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
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.
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.
158Driving tips
Driving and parking

Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18. Rim diameter is part of the tire size and
can be found on the tire sidewall
(
Ypage 317).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to
the higher values:
Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds
iThe tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
a sudden loss of pressure.
For more information, contact a qualified spe-
cialist workshop.
Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or the valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. You can also check the tire
pressure using the on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
The tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight for at least three
hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡ (10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into acco unt when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current operating conditions. If you check the tire
pressure when the tires are warm, the result-
ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire
pressure to the value specified for cold tires.
The tire pressure would otherwise be too low.
