In order to prevent any salt build-up, apply the
R

Servicing the brakes
!
The brake fluid level may be too low, if:
if the red brake warning lamp lights up in
R
the instrument cluster and
you hear a warning tone while the engine is
R
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.
!
A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe-
cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.

The ESP system operates automatically.
The engine and the ignition must therefore be
switched off (the SmartKey must be in posi-
tion 0 or 1 in the ignition lock or the Start/
Stop button must be in position 0 or 1) if the
electric parking brake is tested on a brake
dynamometer.
Braking triggered automatically by ESP
cause severe damage to the brake system.
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.

For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
brake disks that have been approved by
R
Mercedes-Benz
brake pads/linings that have been approved
R
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
disks, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake disks. 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.

The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
will depend on:
Speed

Braking force

Environmental conditions, such as tempera-

The wear of individual components of the brake
system, such as the brake pads/linings or brake
