Important safety notes G
WARNING
Operating mobile communications equip-
ment while driving distracts you from paying
attention to traffic conditions. This could also Features

Z

cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
You must observe the legal requirements for the country in which you are currently driving whenoperating mobile communications equipment in
the vehicle.
If it is permitted by law to operate communica-
tions equipment while the vehicle is in motion,
you may do so only if the traffic situation per-
mits. You may otherwise be distracted from the traffic conditions, cause an accident and injure
yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus-
sion surrounding the possible health risk posed
by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in the
vehicle
R that mutual interference between the vehicle
electronics and mobile phones is minimised
An exterior aerial has the following advantages:
R it conducts the electromagnetic fields gener-
ated by a wireless device to the exterior
R the field strength in the vehicle interior is
lower than in a vehicle that does not have an exterior aerial
Information on retrofitting two-way radios and
mobile phones (RF transmitters) (Y page 358).
General notes Depending on the vehicle equipment, there are
various mobile phone brackets that may be fit-
ted in your vehicle; in some cases, these are
country-specific.
More information on suitable mobile phones,
mobile phone brackets and on connecting Blue-
tooth ®
-capable mobile phones with the multi-
media system can be obtained:
R at a qualified specialist workshop
R on the internet at http://www.mercedes-
benz.com/connect The functions and services available when you
use the phone depend on your mobile phone
model and service provider.

Active bonnet (pedestrian protection) Operating principle
! An active bonnet that had been triggered
must be repaired at a qualified specialist
workshop. The active bonnet function will
then be available again. The additional pedes- trian protection provided by the active bonnet
will then be restored.
The active bonnet is available only in certain
countries.
The active bonnet can reduce the risk of injury to pedestrians in certain accident situations. Rais-
ing the active bonnet increases the clearance to hard components, such as the engine.
If the active bonnet has been triggered, it is
raised at the rear in the area around the hinges by approximately 80 mm. The active bonnet is
triggered by pyrotechnics.
For the drive to the workshop, reset the trig-
gered active bonnet yourself. If the active bon-
net has been triggered, pedestrian protection
may be limited.

products. Cleaning vehicle parts
Cleaning the convertible top !
Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as they
are corrosive and, therefore, can make the
soft-top fabric leak. Do not use high-pressure
cleaning equipment to clean the vehicle. Do
not use sharp-edged equipment to remove ice and snow.
X Light soiling: you can clean the soft top while
it is dry or rinse it with clean water.
X Normal to heavy soiling: clean the soft top
with a brush and clean water. Clean stains
and other dirt with a brush and soft-top clean-
ing agents recommended and approved by
Mercedes-Benz. Always brush from front to
back in the direction of the fabric.
Frequent cleaning reduces the soft top's resist- ance to dirt.
To restore this resistance to dirt, clean the soft
top using soft-top cleaning agents that have
been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as ageing,
can cause the soft-top seams to leak. In such a
case, have the soft-top seams sealed at a quali- fied specialist workshop, e.g. at your Mercedes-
Benz Service Centre. Cover the soft top appropriately if you plan to
leave the vehicle outside for a long period of
time.

ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
! Mercedes‑
AMG C 63 and Mercedes‑ AMG C
63 S with black exhaust pipes: Black chrome trims must not be polished with a chrome
polish as this will cause them to lose their
black shine. To ensure optimum care, the
trims should be rubbed down with a lightly
oiled cloth after each time the car is washed. Commercially available engine and mainte-
nance oils are suitable for use as oil.
In the event of heavier soiling, you may apply a fine lacquer polish with a microfibre cloth.
Remove any excess polish paste after polish-
ing.
Impurities combined with the effects of road grit
and corrosive environmental factors may cause
flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by cleaning it regularly, especially in winter and
after washing the vehicle.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
