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 electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, checkthe maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
! An excessive charge current can blow a
fuse or lead to overheating of the external
power supply. Check whether the external
power supply is compatible with the set
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 in the vehicle cor- responds to the maximum charge current
value.
The default standard value on the charging
cable is the minimum charge current setting.This corresponds to the minimum available
charge current from the power supply. The
value on the charging cable can be increased
and is described in the following section.
i The value of the maximum setting and the
adjustment values may vary depending on
the country. Charging the high-voltage battery (plug-in hybrid vehicles)
213Driving and parking Z

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.

Use the optional quick charging cable when
charging at a wallbox. The charging cable is
stored in a bag in the trunk.
Only use charging cables that have been tes- ted and approved by the manufacturer for
charging the high-voltage battery in an elec-
tric vehicle.

Electric parking brake
General notes G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction in the system, it may not be possible to apply
the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it roll- ing away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a qualified specialist workshop.
The electric parking brake performs a func-
tion test at regular intervals while the engine
is switched off. The sounds that can be heard
while this is occurring are normal. Applying/releasing manually X
To engage: push handle :.
When the electric parking brake is applied, the red F(USA only) or !(Canada
only) indicator lamp lights up in the instru-
ment cluster.
The electric parking brake can also be
applied when the SmartKey is removed.
X To release: pull handle:.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument clus-
ter goes out.
The electric parking brake can only be
released:
R when the SmartKey is in position 1or 2in
the ignition lock (Y page 189) or
R if the ignition was switched on using the
Start/Stop button.
Applying automatically The electric parking brake is automatically
applied when the transmission is in position
P
and:
R the engine is switched off or
R the driver is not wearing a seat belt and the
driver's door is opened.
To prevent the electric parking brake from
being automatically applied, pull handle :.222
ParkingDriving and parking

The electric parking brake is also engaged
automatically if:
R DISTRONIC PLUS brings the vehicle to a
standstill or
R the HOLD function is keeping the vehicle
stationary
R Active Parking Assist is holding the vehicle
at a standstill
In addition, at least one of the following con-
ditions must be fulfilled:
R there is a system malfunction.
R the power supply is insufficient.
R the vehicle is stationary for a lengthy
period.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster
lights up.
The electric parking brake is not automati-
cally engaged if the engine is switched off by the ECO start/stop function.
Releasing automatically The electric parking brake is released auto-
matically when all of the following conditions
are fulfilled:
R the engine is running.
R the transmission is in position Dor R.
R the seat belt has been fastened.
R you depress the accelerator pedal.
If the automatic transmission is in position R,
the trunk lid must be closed.
If your seat belt is not fastened, the following conditions must be fulfilled to automatically
release the electric parking brake:
R the driver's door is closed.
R you have shifted out of transmission posi-
tion Por you have previously driven faster
than 2 mph (3 km/h).
Ensure that you do not depress the acceler-
ator pedal unintentionally. Otherwise the
parking brake will be released and the vehicle
will start to move. Emergency braking The vehicle can also be braked during an
emergency by using the electric parking
brake.
X While driving, push handle :of the electric
parking brake (Y page 222).
The vehicle is braked as long as you keep
handle :of the electric parking brake
pressed. The longer electric parking brake
handle :is depressed, the greater the brak-
ing force.
During braking:
R a warning tone sounds
R the Release parking brake Release parking brake message
appears
R the red F(USA only) or !(Canada
only) indicator lamp in the instrument clus- ter flashes
When the vehicle has been braked to a stand- still, the electric parking brake is engaged. Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging and further damaged
in the event of this occurring again.
X Connect a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than
six weeks, the vehicle may suffer damage as a result of lack of use.
X Visit a qualified specialist workshop and
seek advice.
