273 Towing
Technical
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km/h). The electronic key must be in steering lock
position 2.
To be certain to avoid a possibility of damage to the
transmission, however, we recommend the drive shaft
be disconnected at the rear axle drive flange for any
towing beyond a short tow to a nearby garage.
Do not tow with sling-type equipment. Towing with
sling-type equipment over bumpy roads will damage
radiator and supports.
Use wheel lift, dolly, or flat bed equipment, with
electronic key in steering lock turned to position 0.Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in steering lock to
position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in steering lock
position 0 or 1). Otherwise, the ESP will immediately be
engaged an d will app ly t he r ear wheel b rakes . Swi tch o f f
the tow-away alarm (see page 44) as well as the ESP (see
page 220).
Wa r n i n g !
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.

Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.In the winter, thoroughly remove all traces of road salt
as soon as possible.
When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.

cluster displayPractical hints Car care Index Engine oils
Engine oils are specifically tested for their suitability in
our engines. Therefore, use only engine oils
recommended by Mercedes-Benz. Information on
recommended brands is available at your authorized
Mercedes-Benz Center.
Please follow Service Booklet recommendations for
scheduled oil changes. Failure to do so could result in
engine damage not covered by the Mercedes-Benz
Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil. They may be
harmful to the engine operation.
Damage or malfunctions resulting from blending oil
additives are not covered by the Mercedes-Benz Limited
Warranty.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil
is used in the air conditioner system.
Never use R-12 (CFC) or mineral-based lubricating oil,
otherwise damage to the system will occur.
Brake fluid
During vehicle operation, the boiling point of the brake
fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard
operating conditions, this moisture content can lead to
the formation of bubbles in the system thus reducing
the system’s efficiency.
The brake fluid must therefore be replaced every two
years, preferably in the spring.
It is recommended to use only brake fluid approved by
Mercedes-Benz. Your authorized Mercedes-Benz Center
will provide you with additional information.
