The sockets can be used for accessories with
a maximum current draw of 180 W (15 A), e.g.
lamps or chargers for mobile phones.
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.
i You can also use the sockets when the
ignition is switched off. An emergency cut-
out ensures that the on-board voltage does
not drop too low. If the on-board voltage is
too low, the power to the sockets is
automatically cut. This ensures that there
is sufficient power to start the engine. Socket in the glove box

The battery may drain if the vehicle is left
stationary for long periods. In this case,
Mercedes-Benz recommends attaching the
trickle charger to the charge maintenance
socket.
The charge maintenance socket is designed
solely for connecting a trickle charger. A
trickle charger can be obtained from an
authorized Mercedes-Benz Center, for
example. X
Switch the ignition off.
X Open the trunk lid.
X Connect the cable provided in the trunk to
the trickle charger.
X Connect the trickle charger to charge
maintenance socket 0043. Consult the
manufacturer's operating instructions on
how to do so.
i A trickle charger connected to charge
maintenance socket 0043only maintains the
current charge level of the vehicle's
electrical system battery. If the vehicle's
electrical system battery is discharged, it
needs to be charged with a battery charger.

The service interval display does not take into
account any periods of time during which the
battery is disconnected.
Maintaining the time-dependent service

Points to remember Resetting the service interval display
A qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, will reset
the service interval display after the
necessary service work has been carried out.
You can also obtain further information on
maintenance work, for example.
!
If the service interval display has been
reset unintentionally, have the setting
corrected at a Mercedes-Benz Center.
Have service work carried out as described
in the Maintenance Booklet. This may
otherwise lead to increased wear and
damage to the major assemblies or the
vehicle.
Special service requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating conditions
or increased load on the vehicle,
maintenance work must be carried out more
frequently, for example:
R regular city driving with frequent
intermediate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long
periods 218
MaintenanceMaintenance and care
X
Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
! Maintain a minimum distance of
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, roof gaps, joints, etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures. Cleaning the wheels !
Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park the vehicle for an extended
period right after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
brake pads, thus drying them. The vehicle
can then be parked.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by
inadequate care cannot always be completely
repaired. In such cases, visit a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
X
Remove impurities immediately, where
possible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
If water no longer forms "beads" on the paint
surface, use the paint care products
recommended and approved by Mercedes- Care
