Interior lightingLights and windshield wipers

prevent you from observing the traffic condi-
tions. Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Hold the windshield wiper arm firmly when you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have the wiper blades changed at a qualified
specialist workshop.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles

For information on problems relating to
the charging process, see (Y page 218).
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)

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.

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
