lock if you brake hard, for example.
The steerability and braking characteristics may be severely affec-ted. The braking distance in an emergency braking situation can
increase.

Leave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
X Check the coolant level and add coolant, observing the warning
notes (Y page 537).
X If you need to add coolant more often than usual, have the
engine coolant system checked.
X Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
X At coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop.

Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R The vehicle's operating state
R Incidents
R Malfunctions
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. air bag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature and can be used to:
R assist in recognizing and rectifying mal-
functions and defects
R analyze vehicle functions, e.g. after an acci-
dent
R optimize vehicle function
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor- mation can be read from the event data mem-
ory and malfunction data memory.
Services include, for example:
R repair services
R service processes R
warranties
R quality assurance
It is read by employees of the service network (including manufacturers) using special diag-
nostic devices. More detailed information is
obtained from it, if required.
After a malfunction has been rectified, the
information is deleted from the malfunction
memory or is continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorized
expert), could be traced to a person.
Examples include:
R accident reports
R damages to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Qualified specialist workshop

should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
paintwork
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent dam-
age to the vehicle, deactivate DISTRONIC
PLUS and the HOLD function in the follow-
ing or other similar situations:
R when towing the 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
Cabriolet program. In car washes that use
high water pressures, there is a risk that a
small amount of water may leak into the
vehicle.
! Vehicles with HANDS-FREE ACCESS: if a
SmartKey with KEYLESS-GO is within the
detection range of the KEYLESS-GO
antenna, the following situations could lead
to the unintentional opening of the trunk
lid:
R using a car wash
R using a power washer Make sure that the SmartKey is at least
6.5 ft (2 m) away from the vehicle.
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can damage the paintwork or plastic parts.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that:
R the side windows and the roof are com-
pletely closed
R the climate control blower is switched off
R the windshield wiper switch is at position
0
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind- shield.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in all coun-
tries concerned.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet. 540
