warning tone while the engine is running,
the brake fluid level may be too low.
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. This work should be carried
out at a qualified specialist workshop.
! Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. If you are
planning to have the vehicle tested on such
a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further
information first. Otherwise, you could
damage the drive train or the brake system.
! Vehicles with 4MATIC: as the ESP ®
system operates automatically, the engine
and the ignition must be switched off
(SmartKey in position
0 or 1 in the ignition
lock or Start/Stop button in position 0 or
1) while the parking brake is being tested
on a brake dynamometer.
Braking maneuvers triggered automatically
by ESP
® may seriously damage the brake
system.

system operates automatically, the engine
and the ignition system must be switched
off (SmartKey in position
0 or 1 in the
ignition lock or Start/Stop button in
position
0 or 1) when:
R
testing the parking brake on a brake
dynamometer.
R
you intend to have the vehicle towed with
one of the axles raised.
Braking maneuvers triggered automatically
by ESP
® may seriously damage the brake
system.
All checks and maintenance work on the
brake system must be carried out at a
qualified specialist workshop. Consult a
qualified specialist workshop to arrange this.
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
functionality of your brakes at regular
intervals. To do so, press firmly on the brake
pedal when driving at a high speed. This
improves the grip of the brake pads.
You can find a description of Brake Assist
(BAS) on (
Y page 64) or of BAS PLUS on
( Y page 65).
AMG high-performance and ceramic
brakes
The high-performance brake system is
installed only on the CLS 63 AMG.
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
temperature 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
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your authorized
Mercedes-Benz Center.
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
correspondingly high brake wear. Observe
the brake system warning lamp in the
instrument cluster and note any brake status
messages in the multifunction display. For
