The shelf below the rear window should not be
used to carry objects. This will avoid such objects
from being thrown about and injuring vehicle
occupants during an accident or sudden maneuver.
The trunk is the preferred place to carry objects.Wa r n i n g !
To help avoid personal injury during a collision or
sudden maneuver, exercise care when stowing
things. Put luggage or cargo in the trunk if
possible. Do not pile luggage or cargo higher than
the seat backs. Do not place anything on the shelf

273 Battery
Te ch n ica l

and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in steering lock position 0. The battery
and its filler caps must always be securely installed
when the vehicle is in operation. During removal and
installation always protect the disconnected battery
positive (+) terminal with the cover attached to the
battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.Notes:
After reconnecting the battery also set the clock (see
page 106) resynchronize the front seats (see page 49),
front seat head restraints (see page 49), the express
feature of the power windows (see page 147), and the
electronic stability program (ESP) (see page 221).
If the soft top is in a half open position, it also has to be
synchronized. To do so, raise and lock soft top manually
(see page 291).
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.

Cleaning and care of the vehicle
In operation, your vehicle is subjected to varying
external inf luences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above adverse
influences.More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-
base ru stproof ing in th e body cavities w hich will la st for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Center.
Wa r n i n g !
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.Never use fluids or solvents that are not designed
for cleaning your vehicle.
