Observe the following rules when driving on salt-
treated roads:
R In order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
The brake fluid level may be too low, if:
R if the red brake warning lamp lights up in
the instrument cluster and
R you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately. Consult a qualified specialist workshop to
arrange this.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.
Information on BAS (Brake Assist) (Y page 59).
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
R brake disks that have been approved by
Mercedes-Benz
R brake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake pads/
linings on an axle at the same time. Always
install new brake pads/linings when replacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and threaded connection is matched. The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
AMG high-performance and ceramic
brakes The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
will depend on:
R Speed
R Braking force
R Environmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake system, such as the brake pads/linings or brake
discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An aggressive driving style will lead to high wear.
You can obtain more information on this from a qualified specialist workshop.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. Especially for high performance driving,
it is important to maintain and have the brake
system checked regularly. Driving tips

X
Remove coolant and brake fluid with a moist
cloth and clear water.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull, the paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on the hood while the hood is hot.
X Use a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish care !
Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following can give the paint a glossy
appearance and thus reduce the matt effect:
R Rubbing hard with unsuitable agents
R Washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Only use automatic car washes which cor-
respond to the latest technological stand-
ards. Never use wash programs which finish
by treating the vehicle with hot wax.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
a clear matte finish.
i Use only insect remover and car shampoo
from the range of approved Mercedes-Benz
care products. Cleaning the decorative film !
The following may have an effect on the ser-
vice life and color of decorative film:
R sunlight
R temperature, e.g. hot-air fan
R weather conditions
R stone impacts and dirt
R chemical cleaning agents
R greasy substances
! Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it a shiny finish.
! Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.
Observe the notes in the matte finish paintwork
care and treatment chapter (Y page 244).
These notes also apply for matte decorative
films.
To clean, use plenty of water and a mild cleaning agent without additional or abrasive products,
e.g. a car shampoo approved for Mercedes-
Benz.
X Dry vehicles covered with film using a soft,
absorbent cloth after every wash.
Water marks could otherwise form.
Scratches, corrosive deposits, areas affected by corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove dirt immediately, where possible,
while avoiding rubbing too hard.
The decorative film may be irreparably dam-
aged.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
The Paint Cleaner cleaning product, which has
been approved and recommended for
Mercedes-Benz, should be used when dirt has
penetrated the decorative film surface or the
decorative film has become dull.
The manufacturer can provide you with infor-
mation on special care and cleaning products.
Surfaces covered with a decorative film may,
once a decorative film has been removed, show visual differences from the surfaces that were
not protected by a decorative film. 244
CareMaintenance and care

!
Secure the tow rope or tow bar to the towing
eye only. Otherwise, the vehicle could
become damaged.
! When Active Brake Assist, Active Distance
Assist DISTRONIC or the HOLD function is
activated, the vehicle brakes automatically in
certain situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing the vehicle
R in the car wash
! Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! Shift the automatic transmission to position
005C and do not open the driver's or front-
passenger door when towing the vehicle
away. Otherwise, the automatic transmission may shift to position 005Dwhich can cause
damage to both vehicles.
! Do not tow with sling-type equipment. This
could damage the vehicle.
! You may tow the vehicle for a maximum dis-
tance of 30 miles (50 kilometers). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 kilometers), the entire vehicle must be
raised and transported.
! Observe the transmission fluid temperature
(AMG menu) in the on-board computer when
towing. The transmission oil temperature
must not exceed 250 ‡ (120 †). If this
occurs, you must stop towing immediately.
! Tow-starting the vehicle is not permitted.
The transmission may otherwise be damaged.
Also observe the following notes:
R If the engine does not start, try jump-starting
it (Y page 256). Tow-starting the vehicle is not
permitted.
R If it is not possible to jump-start the vehicle,
have it transported to the nearest qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Service Center. If the vehicle can no longer be driven because of
an accident or breakdown, you have the follow- ing options:
R Transporting the vehicle.
As a rule, you should have the vehicle trans-
ported.
R Towing the vehicle with a tow rope or tow bar.
Only tow the vehicle in exceptional cases. The
engine must be running if you tow the vehicle with a tow rope or tow bar.
If the vehicle has suffered transmission damage, have it transported on a transporter or trailer.
Observe the display messages in the instrument
cluster.
The battery must be connected and charged.
Otherwise, you:
R will not be able to switch on the ignition with
the Start/Stop button
R cannot start the engine
R cannot release the electric parking brake.
R cannot shift the automatic transmission to
position 005C
Disarm the automatic locking feature before the vehicle is towed (Y page 73). You could other-
wise be locked out when pushing or towing the
vehicle. Permitted towing methods
Mercedes-Benz recommends transporting your
vehicle in the case of a breakdown, rather than
towing it away.
When towing away, use a towing rope or a tow-
ing bar with both axles on the ground. Do not use any tow bar systems. Installing/removing the towing eye
Installing the towing eye The bracket for the screw-in towing eye is
behind the radiator trim.
X Remove the towing eye from the vehicle tool
