minimum mark or below, have the 
brake system checked for brake pad 
thickness and leaks immediately. Noti-
fy an authorized Mercedes-Benz Center 
immediately. Do not add brake fluid as 
this will not solve the problem. For 
more information, see also “Practical

303 Operation
Maintenance
Calling up the service indicator
Switch on ignition.
The standard display of the control sys-
tem appears (
page 129).
Press button k or j on the mul-
tifunction steering wheel until FSS indi-
cator with the service symbol 9 or 
´ and the service deadline appears 
in the multifunction display.
Resetting the service indicator 
In the event that the service on your vehi-
cle is not carried out by an authorized 
Mercedes-Benz Center, you can reset the 
service indicator yourself.
Switch on ignition.
The standard display of the control sys-
tem appears (
page 129).
Press button k or j on the mul-
tifunction steering wheel until the FSS 
indicator with the service symbol 9 
or ´ and the service deadline ap-
pears in the multifunction display.
Press reset button to the left in the in-
strument cluster for about three sec-
onds.
This message appears in the multifunc-
tion display:Service interval...
To reset:
Press reset button
for 3 seconds
To confirm, press reset button until you 
hear a signal.
The service indicator now displays the 
reset interval.
iIf the battery is disconnected, the days 
of disconnection will not be included in 
the count shown by the service indica-
tor. To arrive at the true service dead-
line, you will need to subtract these 
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator 
with the engine oil level indicator :.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center 
correct it.
Only reset if the proper service has 
been performed. Resetting the system 
without performing proper service as 
called for by the FSS will cause the FSS 
to incorrectly determine the next ser-
vice interval which will result in engine 
damage not covered by the 
Mercedes-Benz Limited Warranty.

306 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment, 
make sure to protect electrical compo-
nents and connectors from the intrusion of 
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the en-
gine compartment after every engine 
cleaning. Before applying, all control link-
age bushings and joints should be lubricat-
ed. The poly-V-belt and all pulleys should 
be protected from any wax. 
Vehicle washing
Do not use hot water or wash your vehicle 
in direct sunlight. Only use a mild car wash 
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused 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 dry 
with a chamois. Do not allow cleaning 
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle 
through an automatic car wash to prevent 
damage to the mirrors.
In the winter, thoroughly remove all traces 
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Soft top
Clean soft top with soft top raised and 
locked. Lower the soft top into the storage 
compartment only if the soft top is com-
pletely dry. If the soft top is kept in the 
storage compartment for a lengthy period, 
raise it and air out with the windows open 
about every 4 months.
Light colored soft tops should be cleaned 
frequently to prevent spots and dirt from 
setting in, which could stain and discolor 
the soft top material permanently.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of 
water, and a SmartKey with 
KEYLESS-GO* is in close proximity, i.e. 
within approx. 3 ft (approx. 1 m), the 
vehicle could be inadvertently locked 
or unlocked. 
!Remove bird droppings immediately. 
The organic acid damages the material 
and causes the soft top to leak
Never use a power washer to clean the 
soft top, as you may damage the soft 
top material.
Do not use sharp-edged instruments 
for the removal of ice and snow.
