Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Ben zC enter, will reset the
ASSYS TP LUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work ,f or example.
Specia ls ervice requirementsThe specified maintenance interval takes only
the normal operation of the vehicle into
account .U nder arduous operating condition so r
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example: R
regular cit yd rivin gw ith 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 engin eiso ften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eo il and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at aq ualified specialist workshop, e.g.

Automatic car wash
G WARNING
Braking efficienc yisr educed after washing
the vehicle. There is ar isk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
condition su ntil full braking power is restored.
! When DISTRONIC PLUS or the HOL Df unc-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOL Df unction in
the followin gors imilar situations: R
when towin gt he vehicle R
in the car wash
! It is preferable to use car washes with
adjustable high-pressure pre-cleaning that
corresponds to the specification for the Cab-
riolet program. In car washes that use high
water pressures, there is ar isk that as mall
amount of water may leak int ot he vehicle.238
Care
Maintenance and care

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protec tt he engine
cooling system against freezin gd own to
approximately -35 ‡( -37 †).R
not exceed 55% (antifreez ep rotection down
to -49 ‡[ -45 †]). Otherwise, heat will not be
dissipated as effectively
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Servic eP roducts
310.1.
i When the vehicle is first delivered, it is filled
with ac oolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i The coolant is checked with every mainte-
nanc ei nterval at aq ualified specialist work-
shop.

it comes into contact with hot engine compo-
nent sort he exhaust system. There is ar isk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps. ! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give af alse reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
( Y
page 290).
At temperatures above freezing: X
Fill the washer fluid reservoir with am ixture of
water and windshield washer fluid, e.g. MB
SummerFit. X
Add 1p art MB SummerFit to 100 parts water.
At temperatures below freezing: X
Fill the washer fluid reservoir with am ixture of
water and washer fluid, e.g. MB WinterFit.
For the correc tm ixing ratio refer to the infor-
mation on the antifreeze reservoir.
i Add windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round.
