considerable force prior to parking. The heat
generated serves to dry the brakes.
Salt-covered roadsGWarning!
A layer of salt on the brake discs and the brake
linings may cause a delay in the braking
effect, resulting in a significantly increased
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you are
driving on salt-covered roads, so that any
layer of salt that may have built up on the
brake discs and the brake linings is
removed without putting other road users
at risk
R maintain a greater distance to the vehicle
ahead and drive with particular care
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake disc
Brake service
! The brake fluid level in the reservoir may
be too low or the electro-hydraulic brake
system may be malfunctioning if the brake
warning lamp in the instrument cluster
comes on and an acoustic warning sounds
although the parking brake is released.
Observe additional messages in the
multifunction display that may appear.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and use brake fluid
recommended by Mercedes-Benz.GWarning!
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that safe
braking is substantially impaired. This could
result in an accident.
! Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with the front axle raised.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
If your brake system is only subjected to
moderate loads, you should occasionally test
the effectiveness of the brakes by applying
above-normal braking pressure at higher
speeds. This will also enhance the grip of the
brake pads.
GWarning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Refer to the description of the Brake Assist
System (BAS) ( Y page 56).
High-performance brake system

R during winter operation
You should check your vehicle from time to
time for stone chipping or other damage. Any
damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody followed
by a thorough inspection. Damaged areas
need to be re-undercoated.
Your vehicle has been treated at the factory
with a wax-base rustproofing in the body
cavities which will last for the lifetime of the
vehicle. Post-production treatment is neither
necessary nor recommended by Mercedes-
Benz because of the possibility of
incompatibility between materials used in the
production process and others applied later.
We have selected vehicle-care products and
compiled recommendations which are
specially matched to our vehicles and which
always reflect the latest technology. You can
obtain Mercedes-Benz approved vehicle-care
products at an authorized Mercedes-Benz
Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the vehicle-care products recommendedhere. In such cases it is best to seek aid at an
authorized Mercedes-Benz Center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references to
Mercedes-Benz approved vehicle-care
products.
Power washer
! Follow the instructions provided by the
power washer manufacturer on
maintaining a distance between the vehicle
and the nozzle of the power washer.
Never use a round nozzle to power-wash
tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across
the surface. Do not aim directly at electrical
parts, electrical connectors, seals, or other
rubber parts.
i Vehicles with KEYLESS-GO:
If a door handle is hit by a strong jet of
water, and a SmartKey is within
approximately 3 ft (1 m) of the vehicle, it
could be inadvertently locked or unlocked.
Tar stains
Quickly remove tar stains before they dry and
become more difficult to remove. A tar
remover is recommended.
Paintwork, painted body components
! Affixing stickers, magnets, adhesive tape
or similar materials to painted body
components may damage the paintwork.
Mercedes-Benz approved Paint Care should
be applied when water drops on the paint
surface do not “bead up”. This should
normally be done every 3 to 5 months,
depending on the climate and washing
detergent used.
