You could otherwise scratc hord amage the
surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for af ew minutes after cleaning.
Brakin gh eats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked.

G WARNING
Brakin ge fficienc 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
conditions until full braking power is restored.
! If DISTRONIC PLUS or the HOLD function is
activated, the vehicle brakes automatically in
certain situations.
To prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following 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-cleanin gt hat
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 into the vehicle.
! Designo retractable hardtop: make sure
that the vehicle is not subsequently treated
with hot wax.
! Lock the car if you wash it in an automatic
car wash. Otherwise, the vehicle might be
damaged.
! Never clean your vehicle in aT ouchless

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 windshiel da nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.

G WARNING
The water jet from ac ircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amage dint his way may fail unexpect-
edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged tires or chassis component sr eplaced imme-
diately.
! Alway sm aintain ad istance of at least
11.8 in (30 cm) between the vehicle and the

Damaged seals or electrical component sc an
lead to leaks or failures.
! Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
! Do not affix: R
stickers R
films R
magnetic plates or simila ri tems
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate

If tire pressure of 200 kPa (2.0 ba r/ 29 psi )h as
bee na chieved after am aximu mp eriod of ten
minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of the
faulty tire. X
Stow the tire sealant bottle and the tire infla-
tion compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for as hort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly impair the vehicle's braking and driving char-
acteristics. There is ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.

Fuses
Important safety notes
G WARNING
If you manipulate or bridge af aulty fuse or if
you replace it with af use with ah igher amper-
age, the electric cables could be overloaded.
This could result in af ire. There is ar isk of an
accident and injury.
Alway sr eplace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and value .T he fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is located in the vehicle
tool kit in the stowage compartment under the
trunk floor ( Y
page 241).
If an ewly inserted fuse also blows, have the
cause traced and rectified at aq ualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, component sors ystems could be
damaged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If af use blows, all the compo-
nent sont he circuit and their functions stop
operating. Fuses 253

You shoul dr egularl yc heck the pressure of the
emergency spare wheel ,p ar ticularly prior to
long trips, and correct the pressure as neces-
sary ( Y
page 258). The value on the wheel is
valid.
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe

Vehicles with tire pressure monitor: after
mounting an emergency spare wheel ,t he sys-
tem may stil ld is play the tire pressure of the
removed wheel for af ew minutes. The value dis-
played for the mounted emergency spare wheel
is not the same as the current tire pressure of
the emergency spare wheel.
