Charging cable for electrical outlets
Important safety notes
!Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be damaged.
The vehicle is supplied with a country-specific
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.
iIf you use the supplied 12 A charging cable
to charge a high-voltage battery:
Rthe charge time increases considerably
Relectrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station (
Ypage 186). Only
then can certified electrical energy consump-
tion levels be reached.
iThe charging process can vary depending on
the power supply. Therefore, always observe
the local information.
Information about charging from a wallbox can
be found at (
Ypage 185).
Information about charging at a charging station
can be found at (

Setting the maximum charge current
GWARNING
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, check
the 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 cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
Before starting the charging process at a power
socket, check the maximum permissible charge current for the relevant power socket or the
building.
You can set the maximum permissible charge
current:
Ron the controls of the charging cable
Rin the on-board computer menu
(Ypage 272).
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current in the on-board computer menu if:
Rit is not possible to set the charge current on
the charging cable
Rthe precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
How to set the maximum permissible charge
current on the charging cable, is described as
follows.
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 If, after the charging process, the charging cable
is:
Rleft connected to the power socket, the cur-
rently 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 cur-
rent.
iIf 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 comput
er's
menu.

Driving and parking
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.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShift the automatic transmission to position
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 function
test at regular intervals while the engine is
switched off. The sounds that can be heard while
this is occurring are normal.
Applying or releasing manually
XTo engage: push handle :.
When the electric parking brake is applied,

goes out.
The electric parking brake can only be released:
Rwhen the SmartKey is in position 1or 2in the

Applying automatically
The electric parking brake is automatically
applied when the transmission is in position P
and:
Rthe engine is switched off or
Rthe 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 :.
The electric parking brake is also engaged auto- matically if:
RDISTRONIC PLUS brings the vehicle to a
standstill or
Rthe HOLD function is keeping the vehicle sta-
tionary
RActive Parking Assist is keeping the vehicle
stationary
In addition, at least one of the following condi-
tions must be fulfilled:
Rthe engine is switched off
Rthe driver is not wearing a seat belt and the
driver's door is opened
Rthere is a system malfunction
Rthe power supply is insufficient
Rthe vehicle is stationary for a lengthy period
The red F(USA only) or !(Canada only)

Brakes
Important safety notes
GWARNING
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lower gear in good time. This allows you to
take advantage of the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a
drive wheel may not turn for some time, e.g.
on a slippery road surface. This could cause
damage to the drive train. This type of damage
is not covered by the Mercedes-Benz war-
ranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
